The Existential Risk of Math Errors - Gwern.net
How big is this upper bound? Mathematicians have often made errors in proofs. But it’s rarer for ideas to be accepted for a long time and then rejected. But we can divide errors into 2 basic cases corresponding to type I and type II errors:

1. Mistakes where the theorem is still true, but the proof was incorrect (type I)
2. Mistakes where the theorem was false, and the proof was also necessarily incorrect (type II)

Before someone comes up with a final answer, a mathematician may have many levels of intuition in formulating & working on the problem, but we’ll consider the final end-product where the mathematician feels satisfied that he has solved it. Case 1 is perhaps the most common case, with innumerable examples; this is sometimes due to mistakes in the proof that anyone would accept is a mistake, but many of these cases are due to changing standards of proof. For example, when David Hilbert discovered errors in Euclid’s proofs which no one noticed before, the theorems were still true, and the gaps more due to Hilbert being a modern mathematician thinking in terms of formal systems (which of course Euclid did not think in). (David Hilbert himself turns out to be a useful example of the other kind of error: his famous list of 23 problems was accompanied by definite opinions on the outcome of each problem and sometimes timings, several of which were wrong or questionable5.) Similarly, early calculus used ‘infinitesimals’ which were sometimes treated as being 0 and sometimes treated as an indefinitely small non-zero number; this was incoherent and strictly speaking, practically all of the calculus results were wrong because they relied on an incoherent concept - but of course the results were some of the greatest mathematical work ever conducted6 and when later mathematicians put calculus on a more rigorous footing, they immediately re-derived those results (sometimes with important qualifications), and doubtless as modern math evolves other fields have sometimes needed to go back and clean up the foundations and will in the future.7

...

Isaac Newton, incidentally, gave two proofs of the same solution to a problem in probability, one via enumeration and the other more abstract; the enumeration was correct, but the other proof totally wrong and this was not noticed for a long time, leading Stigler to remark:

...

TYPE I > TYPE II?
“Lefschetz was a purely intuitive mathematician. It was said of him that he had never given a completely correct proof, but had never made a wrong guess either.”
- Gian-Carlo Rota13

Case 2 is disturbing, since it is a case in which we wind up with false beliefs and also false beliefs about our beliefs (we no longer know that we don’t know). Case 2 could lead to extinction.

...

Except, errors do not seem to be evenly & randomly distributed between case 1 and case 2. There seem to be far more case 1s than case 2s, as already mentioned in the early calculus example: far more than 50% of the early calculus results were correct when checked more rigorously. Richard Hamming attributes to Ralph Boas a comment that while editing Mathematical Reviews that “of the new results in the papers reviewed most are true but the corresponding proofs are perhaps half the time plain wrong”.

...

Gian-Carlo Rota gives us an example with Hilbert:

...

Olga labored for three years; it turned out that all mistakes could be corrected without any major changes in the statement of the theorems. There was one exception, a paper Hilbert wrote in his old age, which could not be fixed; it was a purported proof of the continuum hypothesis, you will find it in a volume of the Mathematische Annalen of the early thirties.

...

Leslie Lamport advocates for machine-checked proofs and a more rigorous style of proofs similar to natural deduction, noting a mathematician acquaintance guesses at a broad error rate of 1/329 and that he routinely found mistakes in his own proofs and, worse, believed false conjectures30.

]

We can probably add software to that list: early software engineering work found that, dismayingly, bug rates seem to be simply a function of lines of code, and one would expect diseconomies of scale. So one would expect that in going from the ~4,000 lines of code of the Microsoft DOS operating system kernel to the ~50,000,000 lines of code in Windows Server 2003 (with full systems of applications and libraries being even larger: the comprehensive Debian repository in 2007 contained ~323,551,126 lines of code) that the number of active bugs at any time would be… fairly large. Mathematical software is hopefully better, but practitioners still run into issues (eg Durán et al 2014, Fonseca et al 2017) and I don’t know of any research pinning down how buggy key mathematical systems like Mathematica are or how much published mathematics may be erroneous due to bugs. This general problem led to predictions of doom and spurred much research into automated proof-checking, static analysis, and functional languages31.

I don't know any interesting bugs in symbolic algebra packages but I know a true, enlightening and entertaining story about something that looked like a bug but wasn't.

Define sinc𝑥=(sin𝑥)/𝑥.

Someone found the following result in an algebra package: ∫∞0𝑑𝑥sinc𝑥=𝜋/2
They then found the following results:

...

So of course when they got:

∫∞0𝑑𝑥sinc𝑥sinc(𝑥/3)sinc(𝑥/5)⋯sinc(𝑥/15)=(467807924713440738696537864469/935615849440640907310521750000)𝜋

hmm:
Which means that nobody knows Fourier analysis nowdays. Very sad and discouraging story... – fedja Jan 29 '10 at 18:47

Because the most popular systems are all commercial, they tend to guard their bug database rather closely -- making them public would seriously cut their sales. For example, for the open source project Sage (which is quite young), you can get a list of all the known bugs from this page. 1582 known issues on Feb.16th 2010 (which includes feature requests, problems with documentation, etc).

That is an order of magnitude less than the commercial systems. And it's not because it is better, it is because it is younger and smaller. It might be better, but until SAGE does a lot of analysis (about 40% of CAS bugs are there) and a fancy user interface (another 40%), it is too hard to compare.

I once ran a graduate course whose core topic was studying the fundamental disconnect between the algebraic nature of CAS and the analytic nature of the what it is mostly used for. There are issues of logic -- CASes work more or less in an intensional logic, while most of analysis is stated in a purely extensional fashion. There is no well-defined 'denotational semantics' for expressions-as-functions, which strongly contributes to the deeper bugs in CASes.]

...

Should such widely-believed conjectures as P≠NP or the Riemann hypothesis turn out be false, then because they are assumed by so many existing proofs, a far larger math holocaust would ensue38 - and our previous estimates of error rates will turn out to have been substantial underestimates. But it may be a cloud with a silver lining, if it doesn’t come at a time of danger.

https://softwareengineering.stackexchange.com/questions/375342/what-are-the-barriers-that-prevent-widespread-adoption-of-formal-methods
Update: measured effort
In the October 2018 issue of Communications of the ACM there is an interesting article about Formally verified software in the real world with some estimates of the effort.

Interestingly (based on OS development for military equipment), it seems that producing formally proved software requires 3.3 times more effort than with traditional engineering techniques. So it's really costly.

On the other hand, it requires 2.3 times less effort to get high security software this way than with traditionally engineered software if you add the effort to make such software certified at a high security level (EAL 7). So if you have high reliability or security requirements there is definitively a business case for going formal.

WHY DON'T PEOPLE USE FORMAL METHODS?: https://www.hillelwayne.com/post/why-dont-people-use-formal-methods/
You can see examples of how all of these look at Let’s Prove Leftpad. HOL4 and Isabelle are good examples of “independent theorem” specs, SPARK and Dafny have “embedded assertion” specs, and Coq and Agda have “dependent type” specs.6

If you squint a bit it looks like these three forms of code spec map to the three main domains of automated correctness checking: tests, contracts, and types. This is not a coincidence. Correctness is a spectrum, and formal verification is one extreme of that spectrum. As we reduce the rigour (and effort) of our verification we get simpler and narrower checks, whether that means limiting the explored state space, using weaker types, or pushing verification to the runtime. Any means of total specification then becomes a means of partial specification, and vice versa: many consider Cleanroom a formal verification technique, which primarily works by pushing code review far beyond what’s humanly possible.

...

The question, then: “is 90/95/99% correct significantly cheaper than 100% correct?” The answer is very yes. We all are comfortable saying that a codebase we’ve well-tested and well-typed is mostly correct modulo a few fixes in prod, and we’re even writing more than four lines of code a day.

The Law of Leaky Abstractions – Joel on Software
[TCP/IP example]

All non-trivial abstractions, to some degree, are leaky.

...

- Something as simple as iterating over a large two-dimensional array can have radically different performance if you do it horizontally rather than vertically, depending on the “grain of the wood” — one direction may result in vastly more page faults than the other direction, and page faults are slow. Even assembly programmers are supposed to be allowed to pretend that they have a big flat address space, but virtual memory means it’s really just an abstraction, which leaks when there’s a page fault and certain memory fetches take way more nanoseconds than other memory fetches.

- The SQL language is meant to abstract away the procedural steps that are needed to query a database, instead allowing you to define merely what you want and let the database figure out the procedural steps to query it. But in some cases, certain SQL queries are thousands of times slower than other logically equivalent queries. A famous example of this is that some SQL servers are dramatically faster if you specify “where a=b and b=c and a=c” than if you only specify “where a=b and b=c” even though the result set is the same. You’re not supposed to have to care about the procedure, only the specification. But sometimes the abstraction leaks and causes horrible performance and you have to break out the query plan analyzer and study what it did wrong, and figure out how to make your query run faster.

...

- C++ string classes are supposed to let you pretend that strings are first-class data. They try to abstract away the fact that strings are hard and let you act as if they were as easy as integers. Almost all C++ string classes overload the + operator so you can write s + “bar” to concatenate. But you know what? No matter how hard they try, there is no C++ string class on Earth that will let you type “foo” + “bar”, because string literals in C++ are always char*’s, never strings. The abstraction has sprung a leak that the language doesn’t let you plug. (Amusingly, the history of the evolution of C++ over time can be described as a history of trying to plug the leaks in the string abstraction. Why they couldn’t just add a native string class to the language itself eludes me at the moment.)

- And you can’t drive as fast when it’s raining, even though your car has windshield wipers and headlights and a roof and a heater, all of which protect you from caring about the fact that it’s raining (they abstract away the weather), but lo, you have to worry about hydroplaning (or aquaplaning in England) and sometimes the rain is so strong you can’t see very far ahead so you go slower in the rain, because the weather can never be completely abstracted away, because of the law of leaky abstractions.

One reason the law of leaky abstractions is problematic is that it means that abstractions do not really simplify our lives as much as they were meant to. When I’m training someone to be a C++ programmer, it would be nice if I never had to teach them about char*’s and pointer arithmetic. It would be nice if I could go straight to STL strings. But one day they’ll write the code “foo” + “bar”, and truly bizarre things will happen, and then I’ll have to stop and teach them all about char*’s anyway.

...

The law of leaky abstractions means that whenever somebody comes up with a wizzy new code-generation tool that is supposed to make us all ever-so-efficient, you hear a lot of people saying “learn how to do it manually first, then use the wizzy tool to save time.” Code generation tools which pretend to abstract out something, like all abstractions, leak, and the only way to deal with the leaks competently is to learn about how the abstractions work and what they are abstracting. So the abstractions save us time working, but they don’t save us time learning.

CPC Elite Perception of the US since the Early 1990s: Wang Huning and Zheng Bijian as Test Cases
What makes this paper distinct from previous research is that it juxtaposes two of the most influential yet under-studied America watchers within the top echelon of the CPC, Wang Huning and Zheng Bijian. To be sure, the two have indelibly shaped CPC attitudes, yet surprisingly enough, although Zheng has been written about extensively in the English language, Wang has hitherto largely remained outside academics’ purview. This paper also aims, in passing, to explore linkages between Wang and Zheng ideas and those of other well-known America watchers like Liu Mingfu and Yan Xuetong. It is hoped that this comparison will offer clues as to the extent to which the current advisory shaping CPC thinking on the US differs from the previous generation, and as to whether CPC thinking is un-American or anti-American in essence. The conclusions will tie the study together by speculating based on Wang and Zheng’s views about the degree to which New Confucianism, as opposed to Neo-Liberalism, might shape Chinese society in the future.

I want someone to translate Wang Huning’s book “America Against America”
For the record, in Chinese that's《美国反对美国》。Wang traveled across USA in the '80s, visiting big cities and small towns. Book lambasted democracy, contrasting the 'ideal' of American rhetoric with the 'reality' of American life. Wang is now one of Xi's closest advisors.

C++ Core Guidelines
This document is a set of guidelines for using C++ well. The aim of this document is to help people to use modern C++ effectively. By “modern C++” we mean effective use of the ISO C++ standard (currently C++17, but almost all of our recommendations also apply to C++14 and C++11). In other words, what would you like your code to look like in 5 years’ time, given that you can start now? In 10 years’ time?

https://isocpp.github.io/CppCoreGuidelines/
“Within C++ is a smaller, simpler, safer language struggling to get out.” – Bjarne Stroustrup

...

The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management, and concurrency. Such rules affect application architecture and library design. Following the rules will lead to code that is statically type safe, has no resource leaks, and catches many more programming logic errors than is common in code today. And it will run fast - you can afford to do things right.

We are less concerned with low-level issues, such as naming conventions and indentation style. However, no topic that can help a programmer is out of bounds.

Our initial set of rules emphasize safety (of various forms) and simplicity. They may very well be too strict. We expect to have to introduce more exceptions to better accommodate real-world needs. We also need more rules.

...

The rules are designed to be supported by an analysis tool. Violations of rules will be flagged with references (or links) to the relevant rule. We do not expect you to memorize all the rules before trying to write code.

This will be a long wall of text, and kinda random! My main points are:
1. C++ compile times are important,
2. Non-optimized build performance is important,
3. Cognitive load is important. I don’t expand much on this here, but if a programming language or a library makes me feel stupid, then I’m less likely to use it or like it. C++ does that a lot :)

Interview with Donald Knuth | Interview with Donald Knuth | InformIT
Andrew Binstock and Donald Knuth converse on the success of open source, the problem with multicore architecture, the disappointing lack of interest in literate programming, the menace of reusable code, and that urban legend about winning a programming contest with a single compilation.

Reusable vs. re-editable code: https://hal.archives-ouvertes.fr/hal-01966146/document
- Konrad Hinsen

https://www.johndcook.com/blog/2008/05/03/reusable-code-vs-re-editable-code/
I think whether code should be editable or in “an untouchable black box” depends on the number of developers involved, as well as their talent and motivation. Knuth is a highly motivated genius working in isolation. Most software is developed by large teams of programmers with varying degrees of motivation and talent. I think the further you move away from Knuth along these three axes the more important black boxes become.

its-not-software - steveyegge2
You don't work in the software industry.

...

So what's the software industry, and how do we differ from it?

Well, the software industry is what you learn about in school, and it's what you probably did at your previous company. The software industry produces software that runs on customers' machines — that is, software intended to run on a machine over which you have no control.

So it includes pretty much everything that Microsoft does: Windows and every application you download for it, including your browser.

It also includes everything that runs in the browser, including Flash applications, Java applets, and plug-ins like Adobe's Acrobat Reader. Their deployment model is a little different from the "classic" deployment models, but it's still software that you package up and release to some unknown client box.

...

Servware

Our industry is so different from the software industry, and it's so important to draw a clear distinction, that it needs a new name. I'll call it Servware for now, lacking anything better. Hardware, firmware, software, servware. It fits well enough.

Servware is stuff that lives on your own servers. I call it "stuff" advisedly, since it's more than just software; it includes configuration, monitoring systems, data, documentation, and everything else you've got there, all acting in concert to produce some observable user experience on the other side of a network connection.

The Architect as Totalitarian: Le Corbusier’s baleful influence | City Journal
Le Corbusier was to architecture what Pol Pot was to social reform. In one sense, he had less excuse for his activities than Pol Pot: for unlike the Cambodian, he possessed great talent, even genius. Unfortunately, he turned his gifts to destructive ends, and it is no coincidence that he willingly served both Stalin and Vichy.

Lateralization of brain function - Wikipedia
Language
Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right handed individuals.[3] While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers.[4]

Broca's area and Wernicke's area, two areas associated with the production of speech, are located in the left cerebral hemisphere for about 95% of right-handers, but about 70% of left-handers.[5]:69

Auditory and visual processing
The processing of visual and auditory stimuli, spatial manipulation, facial perception, and artistic ability are represented bilaterally.[4] Numerical estimation, comparison and online calculation depend on bilateral parietal regions[6][7] while exact calculation and fact retrieval are associated with left parietal regions, perhaps due to their ties to linguistic processing.[6][7]

...

Depression is linked with a hyperactive right hemisphere, with evidence of selective involvement in "processing negative emotions, pessimistic thoughts and unconstructive thinking styles", as well as vigilance, arousal and self-reflection, and a relatively hypoactive left hemisphere, "specifically involved in processing pleasurable experiences" and "relatively more involved in decision-making processes".

Chaos and Order; the right and left hemispheres: https://orthosphere.wordpress.com/2018/05/23/chaos-and-order-the-right-and-left-hemispheres/
In The Master and His Emissary, Iain McGilchrist writes that a creature like a bird needs two types of consciousness simultaneously. It needs to be able to focus on something specific, such as pecking at food, while it also needs to keep an eye out for predators which requires a more general awareness of environment.

These are quite different activities. The Left Hemisphere (LH) is adapted for a narrow focus. The Right Hemisphere (RH) for the broad. The brains of human beings have the same division of function.

The LH governs the right side of the body, the RH, the left side. With birds, the left eye (RH) looks for predators, the right eye (LH) focuses on food and specifics. Since danger can take many forms and is unpredictable, the RH has to be very open-minded.

The LH is for narrow focus, the explicit, the familiar, the literal, tools, mechanism/machines and the man-made. The broad focus of the RH is necessarily more vague and intuitive and handles the anomalous, novel, metaphorical, the living and organic. The LH is high resolution but narrow, the RH low resolution but broad.

The LH exhibits unrealistic optimism and self-belief. The RH has a tendency towards depression and is much more realistic about a person’s own abilities. LH has trouble following narratives because it has a poor sense of “wholes.” In art it favors flatness, abstract and conceptual art, black and white rather than color, simple geometric shapes and multiple perspectives all shoved together, e.g., cubism. Particularly RH paintings emphasize vistas with great depth of field and thus space and time,[1] emotion, figurative painting and scenes related to the life world. In music, LH likes simple, repetitive rhythms. The RH favors melody, harmony and complex rhythms.

...

Schizophrenia is a disease of extreme LH emphasis. Since empathy is RH and the ability to notice emotional nuance facially, vocally and bodily expressed, schizophrenics tend to be paranoid and are often convinced that the real people they know have been replaced by robotic imposters. This is at least partly because they lose the ability to intuit what other people are thinking and feeling – hence they seem robotic and suspicious.

Oswald Spengler’s The Decline of the West as well as McGilchrist characterize the West as awash in phenomena associated with an extreme LH emphasis. Spengler argues that Western civilization was originally much more RH (to use McGilchrist’s categories) and that all its most significant artistic (in the broadest sense) achievements were triumphs of RH accentuation.

The RH is where novel experiences and the anomalous are processed and where mathematical, and other, problems are solved. The RH is involved with the natural, the unfamiliar, the unique, emotions, the embodied, music, humor, understanding intonation and emotional nuance of speech, the metaphorical, nuance, and social relations. It has very little speech, but the RH is necessary for processing all the nonlinguistic aspects of speaking, including body language. Understanding what someone means by vocal inflection and facial expressions is an intuitive RH process rather than explicit.

...

RH is very much the center of lived experience; of the life world with all its depth and richness. The RH is “the master” from the title of McGilchrist’s book. The LH ought to be no more than the emissary; the valued servant of the RH. However, in the last few centuries, the LH, which has tyrannical tendencies, has tried to become the master. The LH is where the ego is predominantly located. In split brain patients where the LH and the RH are surgically divided (this is done sometimes in the case of epileptic patients) one hand will sometimes fight with the other. In one man’s case, one hand would reach out to hug his wife while the other pushed her away. One hand reached for one shirt, the other another shirt. Or a patient will be driving a car and one hand will try to turn the steering wheel in the opposite direction. In these cases, the “naughty” hand is usually the left hand (RH), while the patient tends to identify herself with the right hand governed by the LH. The two hemispheres have quite different personalities.

The connection between LH and ego can also be seen in the fact that the LH is competitive, contentious, and agonistic. It wants to win. It is the part of you that hates to lose arguments.

Using the metaphor of Chaos and Order, the RH deals with Chaos – the unknown, the unfamiliar, the implicit, the emotional, the dark, danger, mystery. The LH is connected with Order – the known, the familiar, the rule-driven, the explicit, and light of day. Learning something means to take something unfamiliar and making it familiar. Since the RH deals with the novel, it is the problem-solving part. Once understood, the results are dealt with by the LH. When learning a new piece on the piano, the RH is involved. Once mastered, the result becomes a LH affair. The muscle memory developed by repetition is processed by the LH. If errors are made, the activity returns to the RH to figure out what went wrong; the activity is repeated until the correct muscle memory is developed in which case it becomes part of the familiar LH.

Science is an attempt to find Order. It would not be necessary if people lived in an entirely orderly, explicit, known world. The lived context of science implies Chaos. Theories are reductive and simplifying and help to pick out salient features of a phenomenon. They are always partial truths, though some are more partial than others. The alternative to a certain level of reductionism or partialness would be to simply reproduce the world which of course would be both impossible and unproductive. The test for whether a theory is sufficiently non-partial is whether it is fit for purpose and whether it contributes to human flourishing.

...

Analytic philosophers pride themselves on trying to do away with vagueness. To do so, they tend to jettison context which cannot be brought into fine focus. However, in order to understand things and discern their meaning, it is necessary to have the big picture, the overview, as well as the details. There is no point in having details if the subject does not know what they are details of. Such philosophers also tend to leave themselves out of the picture even when what they are thinking about has reflexive implications. John Locke, for instance, tried to banish the RH from reality. All phenomena having to do with subjective experience he deemed unreal and once remarked about metaphors, a RH phenomenon, that they are “perfect cheats.” Analytic philosophers tend to check the logic of the words on the page and not to think about what those words might say about them. The trick is for them to recognize that they and their theories, which exist in minds, are part of reality too.

The RH test for whether someone actually believes something can be found by examining his actions. If he finds that he must regard his own actions as free, and, in order to get along with other people, must also attribute free will to them and treat them as free agents, then he effectively believes in free will – no matter his LH theoretical commitments.

...

We do not know the origin of life. We do not know how or even if consciousness can emerge from matter. We do not know the nature of 96% of the matter of the universe. Clearly all these things exist. They can provide the subject matter of theories but they continue to exist as theorizing ceases or theories change. Not knowing how something is possible is irrelevant to its actual existence. An inability to explain something is ultimately neither here nor there.

If thought begins and ends with the LH, then thinking has no content – content being provided by experience (RH), and skepticism and nihilism ensue. The LH spins its wheels self-referentially, never referring back to experience. Theory assumes such primacy that it will simply outlaw experiences and data inconsistent with it; a profoundly wrong-headed approach.

Gödel’s Theorem proves that not everything true can be proven to be true. This means there is an ineradicable role for faith, hope and intuition in every moderately complex human intellectual endeavor. There is no one set of consistent axioms from which all other truths can be derived.

Theory of Self-Reproducing Automata - John von Neumann
Fourth Lecture: THE ROLE OF HIGH AND OF EXTREMELY HIGH COMPLICATION

Comparisons between computing machines and the nervous systems. Estimates of size for computing machines, present and near future.

Estimates for size for the human central nervous system. Excursus about the “mixed” character of living organisms. Analog and digital elements. Observations about the “mixed” character of all componentry, artificial as well as natural. Interpretation of the position to be taken with respect to these.

Evaluation of the discrepancy in size between artificial and natural automata. Interpretation of this discrepancy in terms of physical factors. Nature of the materials used.

The probability of the presence of other intellectual factors. The role of complication and the theoretical penetration that it requires.

Questions of reliability and errors reconsidered. Probability of individual errors and length of procedure. Typical lengths of procedure for computing machines and for living organisms--that is, for artificial and for natural automata. Upper limits on acceptable probability of error in individual operations. Compensation by checking and self-correcting features.

Differences of principle in the way in which errors are dealt with in artificial and in natural automata. The “single error” principle in artificial automata. Crudeness of our approach in this case, due to the lack of adequate theory. More sophisticated treatment of this problem in natural automata: The role of the autonomy of parts. Connections between this autonomy and evolution.

Christian ethics - Wikipedia
Christian ethics is a branch of Christian theology that defines virtuous behavior and wrong behavior from a Christian perspective. Systematic theological study of Christian ethics is called moral theology, possibly with the name of the respective theological tradition, e.g. Catholic moral theology.

Christian virtues are often divided into four cardinal virtues and three theological virtues. Christian ethics includes questions regarding how the rich should act toward the poor, how women are to be treated, and the morality of war. Christian ethicists, like other ethicists, approach ethics from different frameworks and perspectives. The approach of virtue ethics has also become popular in recent decades, largely due to the work of Alasdair MacIntyre and Stanley Hauerwas.[2]

...

The seven Christian virtues are from two sets of virtues. The four cardinal virtues are Prudence, Justice, Restraint (or Temperance), and Courage (or Fortitude). The cardinal virtues are so called because they are regarded as the basic virtues required for a virtuous life. The three theological virtues, are Faith, Hope, and Love (or Charity).

- Prudence: also described as wisdom, the ability to judge between actions with regard to appropriate actions at a given time
- Justice: also considered as fairness, the most extensive and most important virtue[20]
- Temperance: also known as restraint, the practice of self-control, abstention, and moderation tempering the appetition
- Courage: also termed fortitude, forebearance, strength, endurance, and the ability to confront fear, uncertainty, and intimidation
- Faith: belief in God, and in the truth of His revelation as well as obedience to Him (cf. Rom 1:5:16:26)[21][22]
- Hope: expectation of and desire of receiving; refraining from despair and capability of not giving up. The belief that God will be eternally present in every human's life and never giving up on His love.
- Charity: a supernatural virtue that helps us love God and our neighbors, the same way as we love ourselves.

Seven deadly sins: https://en.wikipedia.org/wiki/Seven_deadly_sins
The seven deadly sins, also known as the capital vices or cardinal sins, is a grouping and classification of vices of Christian origin.[1] Behaviours or habits are classified under this category if they directly give birth to other immoralities.[2] According to the standard list, they are pride, greed, lust, envy, gluttony, wrath, and sloth,[2] which are also contrary to the seven virtues. These sins are often thought to be abuses or excessive versions of one's natural faculties or passions (for example, gluttony abuses one's desire to eat).

originally:
1 Gula (gluttony)
2 Luxuria/Fornicatio (lust, fornication)
3 Avaritia (avarice/greed)
4 Superbia (pride, hubris)
5 Tristitia (sorrow/despair/despondency)
6 Ira (wrath)
7 Vanagloria (vainglory)
8 Acedia (sloth)

Golden Rule: https://en.wikipedia.org/wiki/Golden_Rule
The Golden Rule (which can be considered a law of reciprocity in some religions) is the principle of treating others as one would wish to be treated. It is a maxim that is found in many religions and cultures.[1][2] The maxim may appear as _either a positive or negative injunction_ governing conduct:

- One should treat others as one would like others to treat oneself (positive or directive form).[1]
- One should not treat others in ways that one would not like to be treated (negative or prohibitive form).[1]
- What you wish upon others, you wish upon yourself (empathic or responsive form).[1]
The Golden Rule _differs from the maxim of reciprocity captured in do ut des—"I give so that you will give in return"—and is rather a unilateral moral commitment to the well-being of the other without the expectation of anything in return_.[3]

The concept occurs in some form in nearly every religion[4][5] and ethical tradition[6] and is often considered _the central tenet of Christian ethics_[7] [8]. It can also be explained from the perspectives of psychology, philosophy, sociology, human evolution, and economics. Psychologically, it involves a person empathizing with others. Philosophically, it involves a person perceiving their neighbor also as "I" or "self".[9] Sociologically, "love your neighbor as yourself" is applicable between individuals, between groups, and also between individuals and groups. In evolution, "reciprocal altruism" is seen as a distinctive advance in the capacity of human groups to survive and reproduce, as their exceptional brains demanded exceptionally long childhoods and ongoing provision and protection even beyond that of the immediate family.[10] In economics, Richard Swift, referring to ideas from David Graeber, suggests that "without some kind of reciprocity society would no longer be able to exist."[11]

...

hmm, Meta-Golden Rule already stated:
Seneca the Younger (c. 4 BC–65 AD), a practitioner of Stoicism (c. 300 BC–200 AD) expressed the Golden Rule in his essay regarding the treatment of slaves: "Treat your inferior as you would wish your superior to treat you."[23]

...

The "Golden Rule" was given by Jesus of Nazareth, who used it to summarize the Torah: "Do to others what you want them to do to you." and "This is the meaning of the law of Moses and the teaching of the prophets"[33] (Matthew 7:12 NCV, see also Luke 6:31). The common English phrasing is "Do unto others as you would have them do unto you". A similar form of the phrase appeared in a Catholic catechism around 1567 (certainly in the reprint of 1583).[34] The Golden Rule is _stated positively numerous times in the Hebrew Pentateuch_ as well as the Prophets and Writings. Leviticus 19:18 ("Forget about the wrong things people do to you, and do not try to get even. Love your neighbor as you love yourself."; see also Great Commandment) and Leviticus 19:34 ("But treat them just as you treat your own citizens. Love foreigners as you love yourselves, because you were foreigners one time in Egypt. I am the Lord your God.").

The Old Testament Deuterocanonical books of Tobit and Sirach, accepted as part of the Scriptural canon by Catholic Church, Eastern Orthodoxy, and the Non-Chalcedonian Churches, express a _negative form_ of the golden rule:

"Do to no one what you yourself dislike."

— Tobit 4:15
"Recognize that your neighbor feels as you do, and keep in mind your own dislikes."

— Sirach 31:15
Two passages in the New Testament quote Jesus of Nazareth espousing the _positive form_ of the Golden rule:

Matthew 7:12
Do to others what you want them to do to you. This is the meaning of the law of Moses and the teaching of the prophets.

Luke 6:31
Do to others what you would want them to do to you.

...

The passage in the book of Luke then continues with Jesus answering the question, "Who is my neighbor?", by telling the parable of the Good Samaritan, indicating that "your neighbor" is anyone in need.[35] This extends to all, including those who are generally considered hostile.

Jesus' teaching goes beyond the negative formulation of not doing what one would not like done to themselves, to the positive formulation of actively doing good to another that, if the situations were reversed, one would desire that the other would do for them. This formulation, as indicated in the parable of the Good Samaritan, emphasizes the needs for positive action that brings benefit to another, not simply restraining oneself from negative activities that hurt another. Taken as a rule of judgment, both formulations of the golden rule, the negative and positive, are equally applicable.[36]

The Golden Rule: Not So Golden Anymore: https://philosophynow.org/issues/74/The_Golden_Rule_Not_So_Golden_Anymore
Pluralism is the most serious problem facing liberal democracies today. We can no longer ignore the fact that cultures around the world are not simply different from one another, but profoundly so; and the most urgent area in which this realization faces us is in the realm of morality. Western democratic systems depend on there being at least a minimal consensus concerning national values, especially in regard to such things as justice, equality and human rights. But global communication, economics and the migration of populations have placed new strains on Western democracies. Suddenly we find we must adjust to peoples whose suppositions about the ultimate values and goals of life are very different from ours. A clear lesson from events such as 9/11 is that disregarding these differences is not an option. Collisions between worldviews and value systems can be cataclysmic. Somehow we must learn to manage this new situation.

For a long time, liberal democratic optimism in the West has been shored up by suppositions about other cultures and their differences from us. The cornerpiece of this optimism has been the assumption that whatever differences exist they cannot be too great. A core of ‘basic humanity’ surely must tie all of the world’s moral systems together – and if only we could locate this core we might be able to forge agreements and alliances among groups that otherwise appear profoundly opposed. We could perhaps then shelve our cultural or ideological differences and get on with the more pleasant and productive business of celebrating our core agreement. One cannot fail to see how this hope is repeated in order buoy optimism about the Middle East peace process, for example.

...

It becomes obvious immediately that no matter how widespread we want the Golden Rule to be, there are some ethical systems that we have to admit do not have it. In fact, there are a few traditions that actually disdain the Rule. In philosophy, the Nietzschean tradition holds that the virtues implicit in the Golden Rule are antithetical to the true virtues of self-assertion and the will-to-power. Among religions, there are a good many that prefer to emphasize the importance of self, cult, clan or tribe rather than of general others; and a good many other religions for whom large populations are simply excluded from goodwill, being labeled as outsiders, heretics or … [more]

Eternity in six hours: intergalactic spreading of intelligent life and sharpening the Fermi paradox
We do this by demonstrating that traveling between galaxies – indeed even launching a colonisation project for the entire reachable universe – is a relatively simple task for a star-spanning civilization, requiring modest amounts of energy and resources. We start by demonstrating that humanity itself could likely accomplish such a colonisation project in the foreseeable future, should we want to, and then demonstrate that there are millions of galaxies that could have reached us by now, using similar methods. This results in a considerable sharpening of the Fermi paradox.

The Coming Technological Singularity
Within thirty years, we will have the technological
means to create superhuman intelligence. Shortly after,
the human era will be ended.

Is such progress avoidable? If not to be avoided, can
events be guided so that we may survive? These questions
are investigated. Some possible answers (and some further
dangers) are presented.

_What is The Singularity?_

The acceleration of technological progress has been the central
feature of this century. I argue in this paper that we are on the edge
of change comparable to the rise of human life on Earth. The precise
cause of this change is the imminent creation by technology of
entities with greater than human intelligence. There are several means
by which science may achieve this breakthrough (and this is another
reason for having confidence that the event will occur):
o The development of computers that are "awake" and
superhumanly intelligent. (To date, most controversy in the
area of AI relates to whether we can create human equivalence
in a machine. But if the answer is "yes, we can", then there
is little doubt that beings more intelligent can be constructed
shortly thereafter.
o Large computer networks (and their associated users) may "wake
up" as a superhumanly intelligent entity.
o Computer/human interfaces may become so intimate that users
may reasonably be considered superhumanly intelligent.
o Biological science may find ways to improve upon the natural
human intellect.

The first three possibilities depend in large part on
improvements in computer hardware. Progress in computer hardware has
followed an amazingly steady curve in the last few decades [16]. Based
largely on this trend, I believe that the creation of greater than
human intelligence will occur during the next thirty years. (Charles
Platt [19] has pointed out the AI enthusiasts have been making claims
like this for the last thirty years. Just so I'm not guilty of a
relative-time ambiguity, let me more specific: I'll be surprised if
this event occurs before 2005 or after 2030.)

What are the consequences of this event? When greater-than-human
intelligence drives progress, that progress will be much more rapid.
In fact, there seems no reason why progress itself would not involve
the creation of still more intelligent entities -- on a still-shorter
time scale. The best analogy that I see is with the evolutionary past:
Animals can adapt to problems and make inventions, but often no faster
than natural selection can do its work -- the world acts as its own
simulator in the case of natural selection. We humans have the ability
to internalize the world and conduct "what if's" in our heads; we can
solve many problems thousands of times faster than natural selection.
Now, by creating the means to execute those simulations at much higher
speeds, we are entering a regime as radically different from our human
past as we humans are from the lower animals.

The idea of empire in the "Aeneid" on JSTOR
http://latindiscussion.com/forum/latin/to-rule-mankind-and-make-the-world-obey.11016/
Let's see...Aeneid, Book VI, ll. 851-853:

tu regere imperio populos, Romane, memento
(hae tibi erunt artes), pacique imponere morem,
parcere subiectis et debellare superbos.'

Which Dryden translated as:
To rule mankind, and make the world obey,
Disposing peace and war by thy own majestic way;
To tame the proud, the fetter'd slave to free:
These are imperial arts, and worthy thee."

If you wanted a literal translation,
"You, Roman, remember to rule people by command
(these were arts to you), and impose the custom to peace,
to spare the subjected and to vanquish the proud."

I don't want to derail your thread but pacique imponere morem -- "to impose the custom to peace"
Does it mean "be the toughest kid on the block," as in Pax Romana?

...

That 17th century one is a loose translation indeed. Myself I'd put it as

"Remember to rule over (all) the (world's) races by means of your sovereignty, oh Roman, (for indeed) you (alone) shall have the means (to do so), and to inculcate the habit of peace, and to have mercy on the enslaved and to destroy the arrogant."

http://classics.mit.edu/Virgil/aeneid.6.vi.html
And thou, great hero, greatest of thy name,
Ordain'd in war to save the sinking state,
And, by delays, to put a stop to fate!
Let others better mold the running mass
Of metals, and inform the breathing brass,
And soften into flesh a marble face;
Plead better at the bar; describe the skies,
And when the stars descend, and when they rise.
But, Rome, 't is thine alone, with awful sway,
To rule mankind, and make the world obey,
Disposing peace and war by thy own majestic way;
To tame the proud, the fetter'd slave to free:
These are imperial arts, and worthy thee."

Accurate data on Chinese Christians is hard to access. According to the most recent internal surveys there are approximately 31 million Christians in China today (2.3% of the total population).[5] On the other hand, some international Christian organizations estimate there are tens of millions more, which choose not to publicly identify as such.[6] The practice of religion continues to be tightly controlled by government authorities.[7] Chinese over the age of 18 are only permitted to join officially sanctioned Christian groups registered with the government-approved Protestant Three-Self Church and China Christian Council and the Chinese Patriotic Catholic Church.[8]

https://www.reuters.com/article/us-pope-china-exclusive/exclusive-china-vatican-deal-on-bishops-ready-for-signing-source-idUSKBN1FL67U
Catholics in China are split between those in “underground” communities that recognize the pope and those belonging to a state-controlled Catholic Patriotic Association where bishops are appointed by the government in collaboration with local Church communities.

http://www.bbc.com/news/world-asia-china-42914029
The underground churches recognise only the Vatican's authority, whereas the Chinese state churches refuse to accept the authority of the Pope.

There are currently about 100 Catholic bishops in China, with some approved by Beijing, some approved by the Vatican and, informally, many now approved by both.

...

Under the agreement, the Vatican would be given a say in the appointment of future bishops in China, a Vatican source told news agency Reuters.

For Beijing, an agreement with the Vatican could allow them more control over the country's underground churches.

Globally, it would also enhance China's prestige - to have the world's rising superpower engaging with one of the world's major religions.

Symbolically, it would the first sign of rapprochement between China and the Catholic church in more than half a century.

The Vatican is the only European state that maintains formal diplomatic relations with Taiwan. It is currently unclear if an agreement between China and the Vatican would affect this in any way.

What will this mean for the country's Catholics?

There are currently around 10 million Roman Catholics in China.

The chancellor of the Pontifical Academy of Social Sciences praised the 'extraordinary' Communist state

“Right now, those who are best implementing the social doctrine of the Church are the Chinese,” a senior Vatican official has said.

Bishop Marcelo Sánchez Sorondo, chancellor of the Pontifical Academy of Social Sciences, praised the Communist state as “extraordinary”, saying: “You do not have shantytowns, you do not have drugs, young people do not take drugs”. Instead, there is a “positive national conscience”.

The bishop told the Spanish-language edition of Vatican Insider that in China “the economy does not dominate politics, as happens in the United States, something Americans themselves would say.”

Bishop Sánchez Sorondo said that China was implementing Pope Francis’s encyclical Laudato Si’ better than many other countries and praised it for defending Paris Climate Accord. “In that, it is assuming a moral leadership that others have abandoned”, he added.

...

As part of the diplomacy efforts, Bishop Sánchez Sorondo visited the country. “What I found was an extraordinary China,” he said. “What people don’t realise is that the central value in China is work, work, work. There’s no other way, fundamentally it is like St Paul said: he who doesn’t work, doesn’t eat.”

China, A Fourth Rome?: http://thermidormag.com/china-a-fourth-rome/
As a Chinaman born in the United States, I find myself able to speak to both places and neither. By accidents of fortune, however – or of providence, rather – I have identified more with China even as I have lived my whole life in the West. English is my third language, after Cantonese and Mandarin, even if I use it to express my intellectually most complex thoughts; and though my best of the three in writing, trained by the use of Latin, it is the vehicle of a Chinese soul. So it is in English that for the past year I have memed an idea as unconventional as it is ambitious, unto the Europæans a stumbling-block, and unto the Chinese foolishness: #China4thRome.

This idea I do not attempt to defend rigorously, between various powers’ conflicting claims to carrying on the Roman heritage; neither do I intend to claim that Moscow, which has seen itself as a Third Rome after the original Rome and then Constantinople, is fallen. Instead, I think back to the division of the Roman empire, first under Diocletian’s Tetrarchy and then at the death of Theodosius I, the last ruler of the undivided Roman empire. In the second partition, at the death of Theodosius, Arcadius became emperor of the East, with his capital in Constantinople, and Honorius emperor of the West, with his capital in Milan and then Ravenna. That the Roman empire did not stay uniformly strong under a plurality of emperors is not the point. What is significant about the administrative division of the Roman empire among several emperors is that the idea of Rome can be one even while its administration is diverse.

By divine providence, the Christian religion – and through it, Rome – has spread even through the bourgeois imperialism of the 19th and 20th centuries. Across the world, the civil calendar of common use is that of Rome, reckoned from 1 January; few places has Roman law left wholly untouched. Nevertheless, never have we observed in the world of Roman culture an ethnogenetic pattern like that of the Chinese empire as described by the prologue of Luo Guanzhong’s Romance of the Three Kingdoms 三國演義: ‘The empire, long divided, must unite; long united, must divide. Thus it has ever been.’1 According to classical Chinese cosmology, the phrase rendered the empire is more literally all under heaven 天下, the Chinese œcumene being its ‘all under heaven’ much as a Persian proverb speaks of the old Persian capital of Isfahan: ‘Esfahān nesf-e jahān ast,’ Isfahan is half the world. As sociologist Fei Xiaotong describes it in his 1988 Tanner Lecture ‘Plurality and Unity in the Configuration of the Chinese People’,

...

And this Chinese œcumene has united and divided for centuries, even as those who live in it have recognized a fundamental unity. But Rome, unlike the Chinese empire, has lived on in multiple successor polities, sometimes several at once, without ever coming back together as one empire administered as one. Perhaps something of its character has instead uniquely suited it to being the spirit of a kind of broader world empire. As Dante says in De Monarchia, ‘As the human race, then, has an end, and this end is a means necessary to the universal end of nature, it follows that nature must have the means in view.’ He continues,

If these things are true, there is no doubt but that nature set apart in the world a place and a people for universal sovereignty; otherwise she would be deficient in herself, which is impossible. What was this place, and who this people, moreover, is sufficiently obvious in what has been said above, and in what shall be added further on. They were Rome and her citizens or people. On this subject our Poet [Vergil] has touched very subtly in his sixth book [of the Æneid], where he brings forward Anchises prophesying in these words to Aeneas, father of the Romans: ‘Verily, that others shall beat out the breathing bronze more finely, I grant you; they shall carve the living feature in the marble, plead causes with more eloquence, and trace the movements of the heavens with a rod, and name the rising stars: thine, O Roman, be the care to rule the peoples with authority; be thy arts these, to teach men the way of peace, to show mercy to the subject, and to overcome the proud.’ And the disposition of place he touches upon lightly in the fourth book, when he introduces Jupiter speaking of Aeneas to Mercury in this fashion: ‘Not such a one did his most beautiful mother promise to us, nor for this twice rescue him from Grecian arms; rather was he to be the man to govern Italy teeming with empire and tumultuous with war.’ Proof enough has been given that the Romans were by nature ordained for sovereignty. Therefore the Roman … [more]

'P' Versus 'Q': Differences and Commonalities between the Two Areas of Quantitative Finance by Attilio Meucci :: SSRN
There exist two separate branches of finance that require advanced quantitative techniques: the "Q" area of derivatives pricing, whose task is to "extrapolate the present"; and the "P" area of quantitative risk and portfolio management, whose task is to "model the future."

We briefly trace the history of these two branches of quantitative finance, highlighting their different goals and challenges. Then we provide an overview of their areas of intersection: the notion of risk premium; the stochastic processes used, often under different names and assumptions in the Q and in the P world; the numerical methods utilized to simulate those processes; hedging; and statistical arbitrage.

King Kong and Cold Fusion: Counterfactual analysis and the History of Technology
How “contingent” is technological history? Relying on models from evolutionary epistemology, I argue for an analogy with Darwinian Biology and thus a much greater degree of contingency than is normally supposed. There are three levels of contingency in technological development. The crucial driving force behind technology is what I call S-knowledge, that is, an understanding of the exploitable regularities of nature (which includes “science” as a subset). The development of techniques depend on the existence of epistemic bases in S. The “inevitability” of technology thus depends crucially on whether we condition it on the existence of the appropriate S-knowledge. Secondly, even if this knowledge emerges, there is nothing automatic about it being transformed into a technique that is, a set of instructions that transforms knowledge into production. Third, even if the techniques are proposed, there is selection which reflects the preferences and biases of an economy and injects another level of indeterminacy and contingency into the technological history of nations.

What Does a “Normal” Human Genome Look Like? | Science
So, what have our first glimpses of variation in the genomes of generally healthy people taught us? First, balancing selection, the evolutionary process that favors genetic diversification rather than the fixation of a single “best” variant, appears to play a minor role outside the immune system. Local adaptation, which accounts for variation in traits such as pigmentation, dietary specialization, and susceptibility to particular pathogens is also a second-tier player. What is on the top tier? Increasingly, the answer appears to be mutations that are “deleterious” by biochemical or standard evolutionary criteria. These mutations, as has long been appreciated, overwhelmingly make up the most abundant form of nonneutral variation in all genomes. A model for human genetic individuality is emerging in which there actually is a “wild-type” human genome—one in which most genes exist in an evolutionarily optimized form. There just are no “wild-type” humans: We each fall short of this Platonic ideal in our own distinctive ways.

Friedrich von Hayek, “The Use of Knowledge in Society” (1945)
“The price system is just one of those formations which man has learned to use ... Through it not only a division of labor but also a coördinated utilization of resources based on an equally divided knowledge has become possible.”

“there is beyond question a body of very important but unorganized knowledge which cannot possibly be called scientific in the sense of knowledge of general rules: the knowledge of the particular circumstances of time and place. It is with respect to this that practically every individual has some advantage over all others because he possesses unique information of which beneficial use might be made”

1 Genetics and Crime
The broader construct of antisocial behavior – which includes criminal offending, as well as aggression – also shows substantial genetic influence. In a meta-analysis combining effect sizes in 51 twin and adoption studies, Rhee and Waldman (2002) reported a heritability estimate of 41 per cent, with the remaining 59 per cent of variance being due to environmental factors. Interestingly, when comparing results for various definitions of antisocial behavior, only criminal offending appeared to be influenced by both additive genetic effects and non-additive genetic effects – possibly due to genetic dominance and epistatic interactions between genes – based on a pattern of results whereby, on average, identical (monozygotic) twin correlations are more than twice the value of fraternal (dizygotic) twin correlations, and also that biological parent–offspring correlations are less than fraternal twin correlations. Such non-additive genetic effects could arise if one or more high risk alleles act in a recessive fashion, or if certain alleles at one locus affect gene expression at other loci (epistasis).

One intriguing aspect of the literature on genetics and crime is that the strong and consistent genetic influence seen for property offending does not hold true for violent criminal convictions. None of the major adoption studies in Scandinavia or the United States found any elevated risk for violent convictions as a function of either biological or adoptive parent criminal offending, although one early twin study did find greater identical (monozygotic) than fraternal (dizygotic) concordance for violent convictions (see Cloninger and Gottesman, 1987). This pattern of twin, but not parent-offspring, similarity for violent criminal behavior suggests the possibility of non-additive genetic effects due to dominance or epistasis, which would result in increased resemblance for siblings (and twins), but not for parents and offspring. Thus, there may be genetic risk for violent crimes such as murder and rape, which may stem from rare recessive genes, or specific combinations of alleles that do not appear in studies of vertical transmission across generations.

A Swedish national twin study of criminal behavior and its violent, white-collar and property subtypes: https://www.cambridge.org/core/journals/psychological-medicine/article/a-swedish-national-twin-study-of-criminal-behavior-and-its-violent-white-collar-and-property-subtypes/0D9A88185ED0FD5525A5EBD5D2EBA117
For all criminal convictions, heritability was estimated at around 45% in both sexes, with the shared environment accounting for 18% of the variance in liability in females and 27% in males. The correlation of these risk factors across sexes was estimated at +0.63. In men, the magnitudes of genetic and environmental influence were similar in the three criminal conviction subtypes. However, for violent and white-collar convictions, nearly half and one-third of the genetic effects were respectively unique to that criminal subtype. About half of the familial environmental effects were unique to property convictions.

Heritability, Assortative Mating and Gender Differences in Violent Crime: Results from a Total Population Sample Using Twin, Adoption, and Sibling Models: https://link.springer.com/article/10.1007/s10519-011-9483-0
Using 36k twins, violent crime was moderately heritable (~ 55%) w/ 13% shared environment influence. Using 1.5 mil siblings, heritability was higher for males, & family environment higher for females. Moderate assortative mating for violent crime (r = .4).

In the crude model, an increase of 1 SD in neighbourhood deprivation was associated with a 57% increase in the odds of being convicted of a violent crime (95% CI 52%–63%). The effect was greatly attenuated when adjustment was made for a number of observed confounders (OR 1.09, 95% CI 1.06–1.11). When we additionally adjusted for unobserved familial confounders, the effect was no longer present (OR 0.96, 95% CI 0.84–1.10). Similar results were observed for substance misuse. The results were not due to poor variability either between neighbourhoods or within families.

What did surprise him was that when he looked at families which had started poor and got richer, the younger children—those born into relative affluence—were just as likely to misbehave when they were teenagers as their elder siblings had been. Family income was not, per se, the determining factor.

Three indicators of IPV were measured and genetic factors accounted for 24% of the variance in hitting one's partner, 54% of the variance in injuring one's partner, and 51% of the variance in forcing sexual activity on one's partner. The shared environment explained none of the variance across all three indicators and the nonshared environment explained the remainder of the variance.

Why are children in the same family so different from one another? - PubMed - NCBI
- Plomin et al

The article has three goals: (1) To describe quantitative genetic methods and research that lead to the conclusion that nonshared environment is responsible for most environmental variation relevant to psychological development, (2) to discuss specific nonshared environmental influences that have been studied to date, and (3) to consider relationships between nonshared environmental influences and behavioral differences between children in the same family. The reason for presenting this article in BBS is to draw attention to the far-reaching implications of finding that psychologically relevant environmental influences make children in a family different from, not similar to, one another.

Definite optimism as human capital | Dan Wang
I’ve come to the view that creativity and innovative capacity aren’t a fixed stock, coiled and waiting to be released by policy. Now, I know that a country will not do well if it has poor infrastructure, interest rate management, tax and regulation levels, and a whole host of other issues. But getting them right isn’t sufficient to promote innovation; past a certain margin, when they’re all at rational levels, we ought to focus on promoting creativity and drive as a means to propel growth.

...

When I say “positive” vision, I don’t mean that people must see the future as a cheerful one. Instead, I’m saying that people ought to have a vision at all: A clear sense of how the technological future will be different from today. To have a positive vision, people must first expand their imaginations. And I submit that an interest in science fiction, the material world, and proximity to industry all help to refine that optimism. I mean to promote imagination by direct injection.

...

If a state has lost most of its jobs for electrical engineers, or nuclear engineers, or mechanical engineers, then fewer young people in that state will study those practices, and technological development in related fields slow down a little further. When I bring up these thoughts on resisting industrial decline to economists, I’m unsatisfied with their responses. They tend to respond by tautology (“By definition, outsourcing improves on the status quo”) or arithmetic (see: gains from comparative advantage, Ricardo). These kinds of logical exercises are not enough. I would like for more economists to consider a human capital perspective for preserving manufacturing expertise (to some degree).

I wonder if the so-called developed countries should be careful of their own premature deindustrialization. The US industrial base has faltered, but there is still so much left to build. Until we’ve perfected asteroid mining and super-skyscrapers and fusion rockets and Jupiter colonies and matter compilers, we can’t be satisfied with innovation confined mostly to the digital world.

Those who don’t mind the decline of manufacturing employment like to say that people have moved on to higher-value work. But I’m not sure that this is usually the case. Even if there’s an endlessly capacious service sector to absorb job losses in manufacturing, it’s often the case that these new jobs feature lower productivity growth and involve greater rent-seeking. Not everyone is becoming hedge fund managers and machine learning engineers. According to BLS, the bulk of service jobs are in 1. government (22 million), 2. professional services (19m), 3. healthcare (18m), 4. retail (15m), and 5. leisure and hospitality (15m). In addition to being often low-paying but still competitive, a great deal of service sector jobs tend to stress capacity for emotional labor over capacity for manual labor. And it’s the latter that tends to be more present in fields involving technological upgrading.

...

Here’s a bit more skepticism of service jobs. In an excellent essay on declining productivity growth, Adair Turner makes the point that many service jobs are essentially zero-sum. I’d like to emphasize and elaborate on that idea here.

...

Call me a romantic, but I’d like everyone to think more about industrial lubricants, gas turbines, thorium reactors, wire production, ball bearings, underwater cables, and all the things that power our material world. I abide by a strict rule never to post or tweet about current political stuff; instead I try to draw more attention to the world of materials. And I’d like to remind people that there are many things more edifying than following White House scandals.

...

First, we can all try to engage more actively with the material world, not merely the digital or natural world. Go ahead and pick an industrial phenomenon and learn more about it. Learn more about the history of aviation, and what it took to break the sound barrier; gaze at the container ships as they sail into port, and keep in mind that they carry 90 percent of the goods you see around you; read about what we mold plastics to do; meditate on the importance of steel in civilization; figure out what’s driving the decline in the cost of solar energy production, or how we draw electricity from nuclear fission, or what it takes to extract petroleum or natural gas from the ground.

...

Here’s one more point that I’d like to add on Girard at college: I wonder if to some extent current dynamics are the result of the liberal arts approach of “college teaches you how to think, not what to think.” I’ve never seen much data to support this wonderful claim that college is good at teaching critical thinking skills. Instead, students spend most of their energies focused on raising or lowering the status of the works they study or the people around them, giving rise to the Girardian terror that has gripped so many campuses.

College as an incubator of Girardian terror: http://danwang.co/college-girardian-terror/
It’s hard to construct a more perfect incubator for mimetic contagion than the American college campus. Most 18-year-olds are not super differentiated from each other. By construction, whatever distinctions any does have are usually earned through brutal, zero-sum competitions. These tournament-type distinctions include: SAT scores at or near perfection; being a top player on a sports team; gaining master status from chess matches; playing first instrument in state orchestra; earning high rankings in Math Olympiad; and so on, culminating in gaining admission to a particular college.

Once people enter college, they get socialized into group environments that usually continue to operate in zero-sum competitive dynamics. These include orchestras and sport teams; fraternities and sororities; and many types of clubs. The biggest source of mimetic pressures are the classes. Everyone starts out by taking the same intro classes; those seeking distinction throw themselves into the hardest classes, or seek tutelage from star professors, and try to earn the highest grades.

Mimesis Machines and Millennials: http://quillette.com/2017/11/02/mimesis-machines-millennials/
In 1956, a young Liverpudlian named John Winston Lennon heard the mournful notes of Elvis Presley’s Heartbreak Hotel, and was transformed. He would later recall, “nothing really affected me until I heard Elvis. If there hadn’t been an Elvis, there wouldn’t have been the Beatles.” It is an ancient human story. An inspiring model, an inspired imitator, and a changed world.

Mimesis is the phenomenon of human mimicry. Humans see, and they strive to become what they see. The prolific Franco-Californian philosopher René Girard described the human hunger for imitation as mimetic desire. According to Girard, mimetic desire is a mighty psychosocial force that drives human behavior. When attempted imitation fails, (i.e. I want, but fail, to imitate my colleague’s promotion to VP of Business Development), mimetic rivalry arises. According to mimetic theory, periodic scapegoating—the ritualistic expelling of a member of the community—evolved as a way for archaic societies to diffuse rivalries and maintain the general peace.

As civilization matured, social institutions evolved to prevent conflict. To Girard, sacrificial religious ceremonies first arose as imitations of earlier scapegoating rituals. From the mimetic worldview healthy social institutions perform two primary functions,

They satisfy mimetic desire and reduce mimetic rivalry by allowing imitation to take place.
They thereby reduce the need to diffuse mimetic rivalry through scapegoating.
Tranquil societies possess and value institutions that are mimesis tolerant. These institutions, such as religion and family, are Mimesis Machines. They enable millions to see, imitate, and become new versions of themselves. Mimesis Machines, satiate the primal desire for imitation, and produce happy, contented people. Through Mimesis Machines, Elvis fans can become Beatles.

Volatile societies, on the other hand, possess and value mimesis resistant institutions that frustrate attempts at mimicry, and mass produce frustrated, resentful people. These institutions, such as capitalism and beauty hierarchies, are Mimesis Shredders. They stratify humanity, and block the ‘nots’ from imitating the ‘haves’.

WLGR: The Julian marriage laws (nos. 120-123, etc.)
In 18 B.C., the Emperor Augustus turned his attention to social problems at Rome. Extravagance and adultery were widespread. Among the upper classes, marriage was increasingly infrequent and, many couples who did marry failed to produce offspring. Augustus, who hoped thereby to elevate both the morals and the numbers of the upper classes in Rome, and to increase the population of native Italians in Italy, enacted laws to encourage marriage and having children (lex Julia de maritandis ordinibus), including provisions establishing adultery as a crime.

Jus trium liberorum: https://en.wikipedia.org/wiki/Jus_trium_liberorum
The ius trium liberorum, meaning “the right of three children” in Latin,[1] was a privilege rewarded to Roman citizens who had borne at least three children or freedmen who had borne at least four children.[2] It was a direct result of the Lex Iulia and the Lex Papia Poppaea, bodies of legislation introduced by Augustus in 18 BC and 9 AD, respectively.[3] These bodies of legislation were conceived to grow the dwindling population of the Roman upper classes. The intent of the jus trium liberorum has caused scholars to interpret it as eugenic legislation.[4] Men who had received the jus trium liberorum were excused from munera. Women with jus trium liberorum were no longer submitted to tutela mulierum and could receive inheritances otherwise bequest to their children.[5] The public reaction to the jus trium liberorum was largely to find loopholes, however. The prospect of having a large family was still not appealing.[6] A person who caught a citizen in violation in this law was entitled to a portion of the inheritance involved, creating a lucrative business for professional spies.[7] The spies became so pervasive that the reward was reduced to a quarter of its previous size.[8] As time went on the ius trium liberorum was granted to those by consuls as rewards for general good deeds, holding important professions or as personal favors, not just prolific propagation.[9] Eventually the ius trium liberorum was repealed in 534 AD by Justinian.[10]

Roman Monogamy: http://laurabetzig.org/pdf/RomanMonogamy.pdf
- Laura Betzig

Mating in Rome was polygynous; marriage was monogamous. In the years 18BC and AD 9 the first Roman emperor, Augustus, backed the lex Julia and the lex Papia Poppaea, his “moral” legislation. It rewarded members of the senatorial aristocracy who married and had children; and it punished celibacy and childlessness, which were common. To many historians, that suggests Romans were reluctant to reproduce. To me, it suggests they kept the number of their legitimate children small to keep the number of their illegitimate children large. Marriage in Rome shares these features with marriage in other empires with highly polygynous mating: inheritances were raised by inbreeding; relatedness to heirs was raised by marrying virgins, praising and enforcing chastity in married women, and discouraging widow remarriage; heirs were limited— and inheritances concentrated—by monogamous marriage, patriliny, and primogeniture; and back-up heirs were got by divorce and remarriage, concubinage, and adoption. The “moral” legislation interfered with each of these. Among other things, it diverted inheritances by making widows remarry; it lowered relatedness to heirs by making adultery subject to public, rather than private, sanctions; and it dispersed estates by making younger sons and daughters take legitimate spouses and make legitimate heirs. Augustus' “moral” legislation, like canon law in Europe later on, was not, as it first appears, an act of reproductive altruism. It was, in fact, a form of reproductive competition.

The purpose of writing Ab Urbe Condita was twofold: the first was to memorialize history and the second was to challenge his generation to rise to that same level. He was preoccupied with morality, using history as a moral essay. He connects a nation’s success with its high level of morality, and conversely a nation’s failure with its moral decline. Livy believed that there had been a moral decline in Rome, and he lacked the confidence that Augustus could reverse it. Though he shared Augustus’ ideals, he was not a “spokesman for the regime”. He believed that Augustus was necessary, but only as a short term measure.

Living with Ignorance in a World of Experts
Another kind of track record that we might care about is not about the expert’s performance, qua expert, but about her record of epistemic integrity. This will be important for helping provide reasonably well supported answers to (Q3) and (Q4) in particular. Anderson (2011) offers some related ideas in her discussion of “criteria for judging honesty” and “criteria for judging epistemic responsibility.” Things we might be interested include the following:
• evidence of previous expert-related dishonesty (e.g. plagiarism, faking data)
• evidence of a record of misleading statements (e.g. cherry-picking data, quotations out of context)
• evidence of a record of misrepresenting views of expert opponents
• evidence of evasion of peer-review or refusal to allow other experts to assess work
• evidence of refusal to disclose data, methodology, or detailed results
• evidence of refusal to disclose results contrary to the expert’s own views
• evidence of “dialogic irrationality”: repeating claims after they have been publicly refuted, without responding to the refutations
• evidence of a record of “over-claiming” of expertise: claiming expertise beyond the expert’s domain of expertise
• evidence of a record of “lending” one’s expertise to support other individuals or institutions that themselves lack epistemic integrity in some of the above ways
• evidence of being an “opinion for hire”—offering expert testimony for pay, perhaps particularly if that testimony conflicts with other things the expert has said

The Costly Coordination Mechanism of Common Knowledge: https://www.lesserwrong.com/posts/9QxnfMYccz9QRgZ5z/the-costly-coordination-mechanism-of-common-knowledge
- Dictatorships all through history have attempted to suppress freedom of the press and freedom of speech. Why is this? Are they just very sensitive? On the other side, the leaders of the Enlightenment fought for freedom of speech, and would not budge an inch against this principle.
- When two people are on a date and want to sleep with each other, the conversation will often move towards but never explicitly discuss having sex. The two may discuss going back to the place of one of theirs, with a different explicit reason discussed (e.g. "to have a drink"), even if both want to have sex.
- Throughout history, communities have had religious rituals that look very similar. Everyone in the village has to join in. There are repetitive songs, repetitive lectures on the same holy books, chanting together. Why, of all the possible community events (e.g. dinner, parties, etc) is this the most common type?
What these three things have in common, is common knowledge - or at least, the attempt to create it.

...

Common knowledge is often much easier to build in small groups - in the example about getting off the bus, the two need only to look at each other, share a nod, and common knowledge is achieved. Building common knowledge between hundreds or thousands of people is significantly harder, and the fact that religion has such a significant ability to do so is why it has historically had so much connection to politics.

Fermat's Library | Cassini, Rømer and the velocity of light annotated/explained version.
Abstract: The discovery of the finite nature of the velocity of light is usually attributed to Rømer. However, a text at the Paris Observatory confirms the minority opinion according to which Cassini was first to propose the ‘successive motion’ of light, while giving a rather correct order of magnitude for the duration of its propagation from the Sun to the Earth. We examine this question, and discuss why, in spite of the criticisms of Halley, Cassini abandoned this hypothesis while leaving Rømer free to publish it.

Neue Rheinsiche Zeitung No. 194 January 1849
- Friedrich Engels

The Magyar cause is not in such a bad way as mercenary black-and-yellow [colours of the Austrian flag] enthusiasm would have us believe. The Magyars are not yet defeated. But if they fall, they will fall gloriously, as the last heroes of the 1848 revolution, and only for a short time. Then for a time the Slav counter-revolution will sweep down on the Austrian monarchy with all its barbarity, and the camarilla will see what sort of allies it has. But at the first victorious uprising of the French proletariat, which Louis Napoleon is striving with all his might to conjure up, the Austrian Germans and Magyars will be set free and wreak a bloody revenge on the Slav barbarians. The general war which will then break out will smash this Slav Sonderbund and wipe out all these petty hidebound nations, down to their very names.

The next world war will result in the disappearance from the face of the earth not only of reactionary classes and dynasties, but also of entire reactionary peoples. And that, too, is a step forward.

The Difficulty of Ruling over a Diverse Nation (1578): https://publicdomainreview.org/collections/the-difficulty-of-ruling-over-a-diverse-nation-1578/
16th-century Dutch engraving depicting a fantastical animal with the heads of various other animals sprouting from its body: an allegory for the difficulty of ruling over a diverse nation. In the background, watching on, can be seen a small mob or leaders, both secular and religious. This work by Antwerp-based artist Pieter van der Borcht the Elder, with its image of a confused and troubled body politic, is perhaps just as relevant now as it was then.

this Halloween, "straw men" come to life
http://users.ox.ac.uk/~corp1468/Research_&_Writing_files/Does%20Feminist%20Philosophy_KCL%20talk.pdf
Bauer’s answer to this puzzle is that feminist philosophy must involve a radical reimagining
of philosophy itself – philosophy, to be feminist, must become more
concerned with lived reality, and less concerned with the metaphilosophical goal, as
Bernard Williams put it, of ‘getting it right’ (1989, 3). Thus Bauer endorses the view
that ‘feminist philosophy’ is a sort of contradiction in terms, a contradiction that
must be resolved through a radical revision of philosophy itself.

Voila. This @LizzieWurtzel quote is the logical endpoint of identity epistemology/ethics discourse. Not sarcasm:
https://longreads.com/2017/06/23/exile-in-guyville/
WURTZEL: I see sexism everywhere, and I think it has to do with that. I’ve begun to blame sexism for everything. I’ve become so overwhelmed by it that, even though I love Bob Dylan, I don’t want to listen to Bob Dylan, because I don’t want to listen to men anymore. I don’t care what men have to say about anything. I only want to pay attention to what women do. I only want to read women. I’ll tell you how intense my feelings about this are: You know The Handmaid’s Tale, the show, which is feminist in its nature? Because men are behind it, I don’t want to watch it. That is the extent to which I am so truly horrified by what is going on.

GALILEO'S STUDIES OF PROJECTILE MOTION
During the Renaissance, the focus, especially in the arts, was on representing as accurately as possible the real world whether on a 2 dimensional surface or a solid such as marble or granite. This required two things. The first was new methods for drawing or painting, e.g., perspective. The second, relevant to this topic, was careful observation.

With the spread of cannon in warfare, the study of projectile motion had taken on greater importance, and now, with more careful observation and more accurate representation, came the realization that projectiles did not move the way Aristotle and his followers had said they did: the path of a projectile did not consist of two consecutive straight line components but was instead a smooth curve. [1]

Now someone needed to come up with a method to determine if there was a special curve a projectile followed. But measuring the path of a projectile was not easy.

Using an inclined plane, Galileo had performed experiments on uniformly accelerated motion, and he now used the same apparatus to study projectile motion. He placed an inclined plane on a table and provided it with a curved piece at the bottom which deflected an inked bronze ball into a horizontal direction. The ball thus accelerated rolled over the table-top with uniform motion and then fell off the edge of the table Where it hit the floor, it left a small mark. The mark allowed the horizontal and vertical distances traveled by the ball to be measured. [2]

By varying the ball's horizontal velocity and vertical drop, Galileo was able to determine that the path of a projectile is parabolic.

https://www.scientificamerican.com/author/stillman-drake/

Galileo's Discovery of the Parabolic Trajectory: http://www.jstor.org/stable/24949756

Galileo's Experimental Confirmation of Horizontal Inertia: Unpublished Manuscripts (Galileo
Gleanings XXII): https://sci-hub.tw/https://www.jstor.org/stable/229718
- Drake Stillman

MORE THAN A DECADE HAS ELAPSED since Thomas Settle published a classic paper in which Galileo's well-known statements about his experiments on inclined planes were completely vindicated.' Settle's paper replied to an earlier attempt by Alexandre Koyre to show that Galileo could not have obtained the results he claimed in his Two New Sciences by actual observations using the equipment there described. The practical ineffectiveness of Settle's painstaking repetition of the experiments in altering the opinion of historians of science is only too evident. Koyre's paper was reprinted years later in book form without so much as a note by the editors concerning Settle's refutation of its thesis.2 And the general literature continues to belittle the role of experiment in Galileo's physics.

More recently James MacLachlan has repeated and confirmed a different experiment reported by Galileo-one which has always seemed highly exaggerated and which was also rejected by Koyre with withering sarcasm.3 In this case, however, it was accuracy of observation rather than precision of experimental data that was in question. Until now, nothing has been produced to demonstrate Galileo's skill in the design and the accurate execution of physical experiment in the modern sense.

Pant of a page of Galileo's unpublished manuscript notes, written late in 7608, corroborating his inertial assumption and leading directly to his discovery of the parabolic trajectory. (Folio 1 16v Vol. 72, MSS Galileiani; courtesy of the Biblioteca Nazionale di Firenze.)

...

(The same skeptical historians, however, believe that to show that Galileo could have used the medieval mean-speed theorem suffices to prove that he did use it, though it is found nowhere in his published or unpublished writings.)

...

Now, it happens that among Galileo's manuscript notes on motion there are many pages that were not published by Favaro, since they contained only calculations or diagrams without attendant propositions or explanations. Some pages that were published had first undergone considerable editing, making it difficult if not impossible to discern their full significance from their printed form. This unpublished material includes at least one group of notes which cannot satisfactorily be accounted for except as representing a series of experiments designed to test a fundamental assumption, which led to a new, important discovery. In these documents precise empirical data are given numerically, comparisons are made with calculated values derived from theory, a source of discrepancy from still another expected result is noted, a new experiment is designed to eliminate this, and further empirical data are recorded. The last-named data, although proving to be beyond Galileo's powers of mathematical analysis at the time, when subjected to modern analysis turn out to be remarkably precise. If this does not represent the experimental process in its fully modern sense, it is hard to imagine what standards historians require to be met.

The discovery of these notes confirms the opinion of earlier historians. They read only Galileo's published works, but did so without a preconceived notion of continuity in the history of ideas. The opinion of our more sophisticated colleagues has its sole support in philosophical interpretations that fit with preconceived views of orderly long-term scientific development. To find manuscript evidence that Galileo was at home in the physics laboratory hardly surprises me. I should find it much more astonishing if, by reasoning alone, working only from fourteenth-century theories and conclusions, he had continued along lines so different from those followed by profound philosophers in earlier centuries. It is to be hoped that, warned by these examples, historians will begin to restore the old cautionary clauses in analogous instances in which scholarly opinions are revised without new evidence, simply to fit historical theories.

In what follows, the newly discovered documents are presented in the context of a hypothetical reconstruction of Galileo's thought.

...

As early as 1590, if we are correct in ascribing Galileo's juvenile De motu to that date, it was his belief that an ideal body resting on an ideal horizontal plane could be set in motion by a force smaller than any previously assigned force, however small. By "horizontal plane" he meant a surface concentric with the earth but which for reasonable distances would be indistinguishable from a level plane. Galileo noted at the time that experiment did not confirm this belief that the body could be set in motion by a vanishingly small force, and he attributed the failure to friction, pressure, the imperfection of material surfaces and spheres, and the departure of level planes from concentricity with the earth.5

It followed from this belief that under ideal conditions the motion so induced would also be perpetual and uniform. Galileo did not mention these consequences until much later, and it is impossible to say just when he perceived them. They are, however, so evident that it is safe to assume that he saw them almost from the start. They constitute a trivial case of the proposition he seems to have been teaching before 1607-that a mover is required to start motion, but that absence of resistance is then sufficient to account for its continuation.6

In mid-1604, following some investigations of motions along circular arcs and motions of pendulums, Galileo hit upon the law that in free fall the times elapsed from rest are as the smaller distance is to the mean proportional between two distances fallen.7 This gave him the times-squared law as well as the rule of odd numbers for successive distances and speeds in free fall. During the next few years he worked out a large number of theorems relating to motion along inclined planes, later published in the Two New Sciences. He also arrived at the rule that the speed terminating free fall from rest was double the speed of the fall itself. These theorems survive in manuscript notes of the period 1604-1609. (Work during these years can be identified with virtual certainty by the watermarks in the paper used, as I have explained elsewhere.8)

In the autumn of 1608, after a summer at Florence, Galileo seems to have interested himself in the question whether the actual slowing of a body moving horizontally followed any particular rule. On folio 117i of the manuscripts just mentioned, the numbers 196, 155, 121, 100 are noted along the horizontal line near the middle of the page (see Fig. 1). I believe that this was the first entry on this leaf, for reasons that will appear later, and that Galileo placed his grooved plane in the level position and recorded distances traversed in equal times along it. Using a metronome, and rolling a light wooden ball about 4 3/4 inches in diameter along a plane with a groove 1 3/4 inches wide, I obtained similar relations over a distance of 6 feet. The figures obtained vary greatly for balls of different materials and weights and for greatly different initial speeds.9 But it suffices for my present purposes that Galileo could have obtained the figures noted by observing the actual deceleration of a ball along a level plane. It should be noted that the watermark on this leaf is like that on folio 116, to which we shall come presently, and it will be seen later that the two sheets are closely connected in time in other ways as well.

The relatively rapid deceleration is obviously related to the contact of ball and groove. Were the ball to roll right off the end of the plane, all resistance to horizontal motion would be virtually removed. If, then, there were any way to have a given ball leave the plane at different speeds of which the ratios were known, Galileo's old idea that horizontal motion would continue uniformly in the absence of resistance could be put to test. His law of free fall made this possible. The ratios of speeds could be controlled by allowing the ball to fall vertically through known heights, at the ends of which it would be deflected horizontally. Falls through given heights … [more]

No, Politics Is Not About Power – Arc Digital
What does it mean to say that politics is a contest of domination? For Robinson, “there are conflicting interests in society, and they are deep.” One side has value V, the other value not-V, so “there is no available compromise. There is only a test to see which one of us can have our values enacted in the world.” Conservative values, he says, “are that people should struggle for subsistence in a miserably unequal, sexist, and racist economy.” But to centrist liberals, “compromise is a goal rather than a tactic.” So, according to Robinson, these liberals end up allowing conservatives to inflict the immiseration they so desire upon the world.

This is a wild caricature, of course. But even in terms of his basic logic Robinson is doing some projecting here. For it is “dominance” as a tactic, not as a goal, that Heer critiques, and no tactical justification is given in response.

Freddie deBoer has wondered: “Why is it forbidden to say ‘I support your goals, but I find your tactics, your strategy, and your messaging counterproductive’?” Nothing against Freddie (and compare his views to mine), but the answer is common sense: If the people in question cared more about their goals than about their tactics, then they wouldn’t have such ridiculous tactics in the first place. They would be actually winning rather than talking, on podcasts and in online journals, about winning.

‘Tactics’ Are Not the Problem with Antifa: http://www.nationalreview.com/article/451092/antifa-violence-tactics-anger-politics-attacks-liberals-too
But isn’t this a familiar pattern by now? For the most part, in American political discourse, we — whether we’re conservatives or liberals ourselves — condemn those to our left on strategic grounds and those to our right on moral grounds. Thus we are constantly trying to explain to those on our left that we share their values, that we have their best interests at heart when we express our strategic considerations; and to those on our right that we don’t share their values, that their strategic considerations have no bearing on our interests. With our right hands, we push (punch?); with our left hands, pull toward.

Kenneth Minogue’s “Christophobia” and the West – Old School Contemporary
from the New Criterion

The failure of Communism was consecrated in the fall of the Soviet Union. The remarkable thing is that, as in most cases when prophecy fails, the faith never faltered. Indeed, an alternative version had long been maturing, though cast into the shadows for a time by enthusiasm for the quick fix of revolution. It had, however, been maturing for at least a century and already had a notable repertoire of institutions available. We may call it Olympianism, because it is the project of an intellectual elite that believes that it enjoys superior enlightenment and that its business is to spread this benefit to those living on the lower slopes of human achievement. And just as Communism had been a political project passing itself off as the ultimate in scientific understanding, so Olympianism burrowed like a parasite into the most powerful institution of the emerging knowledge economy—the universities.

We may define Olympianism as a vision of human betterment to be achieved on a global scale by forging the peoples of the world into a single community based on the universal enjoyment of appropriate human rights. Olympianism is the cast of mind dedicated to this end, which is believed to correspond to the triumph of reason and community over superstition and hatred. It is a politico-moral package in which the modern distinction between morals and politics disappears into the aspiration for a shared mode of life in which the communal transcends individual life. To be a moral agent is in these terms to affirm a faith in a multicultural humanity whose social and economic conditions will be free from the causes of current misery. Olympianism is thus a complex long-term vision, and contemporary Western Olympians partake of different fragments of it.

To be an Olympian is to be entangled in a complex dialectic involving elitism and egalitarianism. The foundational elitism of the Olympian lies in self-ascribed rationality, generally picked up on an academic campus. Egalitarianism involves a formal adherence to democracy as a rejection of all forms of traditional authority, but with no commitment to taking any serious notice of what the people actually think. Olympians instruct mortals, they do not obey them. Ideally, Olympianism spreads by rational persuasion, as prejudice gives way to enlightenment. Equally ideally, democracy is the only tolerable mode of social coordination, but until the majority of people have become enlightened, it must be constrained within a framework of rights, to which Olympian legislation is constantly adding. Without these constraints, progress would be in danger from reactionary populism appealing to prejudice. The overriding passion of the Olympian is thus to educate the ignorant and everything is treated in educational terms. Laws for example are enacted not only to shape the conduct of the people, but also to send messages to them. A belief in the power of role models, public relations campaigns, and above all fierce restrictions on raising sensitive questions devant le peuple are all part of pedagogic Olympianism.

...

One of the central problems of Olympianism has always been with the nation state and its derivative, nationalism. A world of nation states is one of constant potential antipathy. It makes something of a mockery of the term “world community.” Hence it is a basic tenet of Olympianism that the day of the nation state has gone. It is an anachronism. And on this point, events have played into the hands of this project. The homogeneity of these nation states is a condition of democracy, but it also facilitates the wars in which they have engaged. If, however, homogeneity were to be lost as states became multicultural, then they would turn into empires, and their freedom of action would be seriously constrained. Empires can only be ruled, to the extent that they are ruled, from the top. They are ideal soil for oligarchy. Olympianism is very enthusiastic about this new development, which generates multiculturalism. Those who rule a rainbow society will have little trouble with an unruly national will, because no such thing remains possible. The Olympian lawyer and administrator will adjudicate the interests of a heterogeneous population according to some higher set of principles. Indeed, quite a lot of this work can be contracted out to independent agencies of the state, agencies whose judgments lead on to judicial tribunals in cases of conflict. This is part of a process in which the autonomy of civil institutions (of firms to employ whom they want, of schools to teach curricula they choose, and so on) is steadily eroded by centralized standards. Multiculturalism in the name of abstract moral standards has the effect of restricting freedom across the board.
