Going back to finishing Rulers, Religion, and Riches: Why the West Got Rich and the Middle East Did Not. My general attitude so far is that I’m skeptical, but the author presents a plausible thesis. Additionally, the book is worth reading because of its engagement with the whole literature in this area. It’s got a good bibliography you can follow-up.

We had Shadi Hamid on the Brown Pundits podcast. Really appreciate Shadi’s interest in engaging with a diverse array of people. A real intellectual for our time, and unfortunately all too rare in many places these days (I think Shadi should go on the Extremely Offline podcast, even though he is extremely online).

There’s a Fake Outrage Machine on the Right, Also. Basically, they’re trying to get a professor fired for saying in some forum several years ago that cops should be killed. This is egregious, but one of the features of academia, as it is today, is that egregiousness is defended.

Some people are making the analogy to the professor who is under fire at Sarah Lawrence, who wrote an op-ed suggesting there needs to be more intellectual diversity in academia. That’s a pretty weird comparison, but I guess it tells you something. If you are conservative your very existence is scary. If you are on the Left, suggesting people should be killed is scary. But look, there are literal Communists in the academy. No one is demanding they be fired, and unless you add all sorts of caveats being a Communist often means you believe in violent revolution against a class of people. Being liberal in the broad sense is illustrated only when it’s hard, not when it’s easy.

A conservative assault on academia may need to occur, but it shouldn’t be around small things like a professor here and there. Go for the money. That’s the heart. Crazy professors are like stray strands of hair.

The Stanford professor who rejected one of Elizabeth Holmes’ early ideas explains what it was like to watch the rise and fall of Theranos. If you listened to The Dropout, you get the feeling that Dr. Phyllis Gardner was the hero we didn’t deserve. It must have been difficult to watch what has happened over the past 15 years for her. She knew it was fake all along.

Immune Gene Diversity in Archaic and Present-day Humans. Starting to think that the low diversity and population sizes of northern humans were a long-term problem, and one reason they were absorbed by southern modern humans. Not totally sure though.

Jomon genome sheds light on East Asian population history.

Shared polygenetic variation between ASD and ADHD exerts opposite association patterns with educational attainment.

The Scandals of Meritocracy. Virtue vs. competence. Would you rather have a boss who is evil but competent, or good but incompetent? The reality is you have to balance the two. Richard Nixon was probably smarter that Dwight Eisenhower in raw g, but Eisenhower was probably a better person.

Indian population is growing much faster in the north – and the south is paying the price. Much of South India is below replacement. Kerala’s fertility is similar to Japan’s. The Gangetic core of North India is well above replacement. The state of Bihar has 100 million people and a total fertility rate of 3.41. That’s similar to Pakistan’s.

Classic Mechanism of Epigenetic Inheritance Is Rare, Not the Rule. Some geneticists are in “but we all knew that” mode. But the reality is that going by the popular press the public doesn’t know that. The unfortunate reality is that scientific revolutions don’t come around that often.

Again, recommend Nature’s Metropolis: Chicago and the Great West. Great book.

Creating Christian Marriage in Early Islamic Arabia:

…perhaps the earliest, of a churchman saying definitively that marriage isn’t marriage without a specific Christian ritual comes from an unexpected corner of the late antique world: the Persian Gulf island of Dayrin (modern Tarut in Saudi Arabia) under the rule of the early Muslim caliphate. On this island in 676, Patriarch George I—chief bishop of the Church of the East, one of the two main churches of the Syriac Christian tradition—issued a canon that only unions that received a priestly blessing would be recognized as legitimate, lawful marriage….

…Patriarch George’s writings suggest that East Arabian Christians habitually drank at Jewish taverns and participated in “pagan” funerals—pagan, that is, in their “un-Christian” ostentatiousness. Significantly, interreligious mixing extended into family relations too. George complains of Christian women marrying “pagans,” here meaning Muslims….

I’m not a total revisionist. But not the date. 676. Contrary to traditional Islamic historiography I think it is highly plausible, even probably, that these men would not have been “Muslims” as we’d conceive of them. Rather, Islam, as we’d understand it really, makes sense only from 750 AD and later, with the emergence of the Sunni ulema, the turn against philosophy in mainstream Islam, and the focus on religious legalism. No Bukhari, no Islam.

This brings me to another issue that emerged in a discussion with a reader about Brown Pundits. Some Hindus say that their religion is founded in the Vedas. Similarly, though traditional most Muslims (Shia and Sunni) ground their faith in customs and traditions which accrued organically in the centuries after the death of Muhammad, they will assert that the fundamental basis of their religion goes back to Muhammad and that Islam qua Islam exploded out of the deserts of Arabia under the Rashidun.

From the perspective of the nonbeliever, I think both narratives miss important cultural genealogical features of the development of “Hinduism” and “Islam.” Hindus believe that their religion is the tradition of the Aryans. I hold that the Aryan, Indo-European, traditions that are present within Hinduism are calcified fossils, artifacts which symbolic meaning, but that the core of Dharmic traditions, whether Hindu or Buddhist or Jain, are not fundamentally from the Indo-Europeans. Some intellectual historians suggest that the Sramanic traditions, the counter-Hindu movements, are a revolt of the indigenous non-Aryan components. But I think the same is arguably true of Puranic Hinduism. All of these religions are qualitatively different from the sacrificial ritualism of the pastoralist Aryans.

Similarly, with Islam it is no secret that I am sympathetic with the argument that the emergence of the mawālī, non-Arabs, within Islam after 750 A.D. fundamentally transformed from the religion. Whereas proto-Islam under the Umayyads crystallized was the cult of the ruling caste, an Arab peculiarity, under the Abbasids, who saw the waxing of Iranian culture within the Caliphate, Islam became the religion of the state, and eventually the dominant element of the society. Though I would argue that the influence of Iran and Turan on Islam is probably quantitatively less than that of non-Aryan India on Hinduism, the transformation is great enough that I think one can make a similar case that Islam, a post-Christian Arab ruling sect, was “hijacked” by Iranian and Turanian modalities under the Abbasids.

Again, to be clear, I am not interested in “explaining” to Muslims or Hindus that “actually….” their religion isn’t what they think it is. I’m trying to get a better sense of cultural development and relatedness from the perspective of non-believers.

Biotic interactions affect fitness across latitudes, but only drive local adaptation in the tropics. This surprised me at first blush.

A week ago I had a conversation with Thomas Chatterton Williams for the BrownCast. One thing that we both agreed on: we hate Twitter, but we can’t leave it. Also, lots of people on Twitter are very stupid. I used to think commenters on this blog were stupid, but the reality is that you are geniuses among the dull compared to the Twitter mobs.

Why Elites Dislike Standardized Testing. The reality is that the gains to test-prep are not that great. ETS works really hard on this. But if you read Twitter or many mainstream commentators they act as if test-prep is driving the inequalities. It’s not. The world is full of bullshit.

Thanks to everyone who has gotten a membership. Still working out a few kinks and trying to enable yearly billing and Papyal (I’m messing up something on the Paypal API). Since someone asked, here is my Patreon for the Brown Pundits podcast.

Speaking of that, I’ll be posting a conversation with an Indian middle-class Dalit soon (already posted for patrons), as well as interviews pending for Thomas Chatterton Williams and Shadi Hamid.

The Insight will have Alicia Martin on this week, and then Lara Cassidy on Irish genetic history, as well as something on historical linguistics by Asya Pereltsvaig. Yeah, we’re preloaded for the next month! Then the current plan is to talk about deep ancient structure in our complex species.

I’ve been thinking about Twitter, comments, papers, books, and blog posts recently. And the audacious argument in Christopher Beckwith’s Warriors of the Cloisters: The Central Asian Origins of Science in the Medieval World. Beckwith renames what we know as the scholastic method as the “recursive argument method.” His contention is that this method developed in the viharas, colleges, of Central Asian Iranian Buddhism before the rise of Islam. With the conversion of these Buddhist peoples to Islam, their intellectual traditions were assimilated into the Islamic one. While the vihara became madrassas, which spread from the Islamic east to the west, the disputation techniques were never fully integrated into Islamic civilization, even though Central Asian Iranians such as Avicenna continued the tradition. Eventually, the tradition did take root in the Latin West, being transmitted by Islamic civilization.

Here is the Wikipedia definition of scholasticism:

Scholasticism is not so much a philosophy or a theology as a method of learning, as it places a strong emphasis on dialectical reasoning to extend knowledge by inference and to resolve contradictions. Scholastic thought is also known for rigorous conceptual analysis and the careful drawing of distinctions. In the classroom and in writing, it often takes the form of explicit disputation; a topic drawn from the tradition is broached in the form of a question, opponents’ responses are given, a counterproposal is argued and opponents’ arguments rebutted. Because of its emphasis on rigorous dialectical method, scholasticism was eventually applied to many other fields of study.

Scholasticism is basically enforced nerdiness. Beckwith argues that modernist humans have abandoned this tradition, and he argues that postmodernism is really just a form of late-stage modernism. While in scholasticism the method and substance of the argument are critical, in postmodernism the individual who is making the argument is arguably even more important.

If a wealthy white male and a poor black woman entered into the argument as to whether “income inequality was bad for society,” we (post)moderns would place a great deal of weight upon who the disputants were, no matter the substance of their arguments.

The recursive argument technique is thorough, exhaustive and requires space. One can see scholasticism playing out in the form of a book-length argument, or in an extended paper. But it is almost impossible to imagine that its well-structured method could be format could be fitted to the comments of an article or blog post, let alone Twitter.

Twitter, in particular, is extremely well suited for a who/whom style of argument. Aside from threading it lacks the ability to structure arguments in a complex manner, and, its 280 character limit enforces a level of brevity at the single tweet scale. Deep substantive disagreements are almost never hashed out on Twitter because the platform does not have the capacity, goodwill or no. Rather, short rhetorical bursts and quips are optimized to lift the spirits of conferences in fellowship, ostracize heretics, and demonize the opposition. The laconic sophist is the ideal user of the platform.

Will be reading This View of Life: Completing the Darwinian Revolution soon. Hope to have the author on the podcast at some point.

Very heartened to see the author of This View of Life: Completing the Darwinian Revolution, David Sloan Wilson, rejecting attempts to smear and taint Bret Weinstein with guilt by association. Wilson expressed an old-fashioned liberal sense of fair play and decency which seemed totally out of place in a place like Twitter.

Some of the idiots on Twitter once asked me “I wonder how it makes you feel that Ann Coulter retweeted you” in relation to a tweet that “blew up” (I don’t remember what it was). Now Illan Omar is having her words retweeted by the froggish sect for obvious reasons. How does it make her feel? I assume whatever her feelings are they are sincere and deeply felt, and whatever agreements frogs might have with her is neither here nor there to her. At least she cares about the substance of her beliefs, whether you think they are good or bad, not vague posturing associations.

The cult of feeling and naked emotive reflex reigns supreme today. Reason, for ill or goodwill, is at least bracing in its clarity.

The game is on. Let the disputes begin!

Peter Turchin’s Ages of Discord is now a free rental if you have Amazon Prime (otherwise you will be prompted for a Kindle Unlimited subscription). If you are interested in the kind of stuff I talk about, I highly recommend all of Peter Turchin’s work. For readers of this weblog Historical Dynamics: Why States Rise and Fall and War and Peace and War: The Life Cycles of Imperial Nations would be of most interest.

Speaking of Peter, check out his recent blog post, An Anarchist View of Human Social Evolution, which is basically a critique of the two of scholars and an essay, Are we city dwellers or hunter-gatherers? The interesting sociological aspect is that one of the scholars is a pretty unpleasant disputant with critics on social media…and that seems to redound to his fame and influence. Unfortunate incentives.

An Honest Living: What is it like to go from a tenured professorship to an hourly wage driving buses? This piece tries to make sense of an unusual transition. The author is, to be frank, kind of a dick. But there are lots of people with unpleasant and intolerable personalities in academia.

President’s Day sale and DNAGEEKS. Put in the code “PREZ” and you are good to go.

Speaking of presidents, you probably know about The Age of Jackson. A more recent book, The Age of Lincoln is worth reading. And, if you want to get more contemporary views for and against Jacksonianism, The Rise of American Democracy: Jefferson to Lincoln and What Hath God Wrought: The Transformation of America, 1815-1848.

The post below, The End Of America As The World As We Know It, is gated. But the first two posts should be free. And since the gating is leaky if you want to deal with the hassle you should be able to figure out how to get access (I’m going to make them free after 30 days as well).

The biography of Maximinus Thrax is on sale as Kindle. A lot of the Roman history stuff that is discounted is kind of like a Wikipedia entry, but this biography comes from a serious scholar and has some reviews that are positive from legitimate people. Thrax is a bit of a turning point character, ushering in the period when the Roman Empire was under serious threat from without and within.

Jussie Smollett. I wish there were betting markets for this sort of stuff. Also, those guys were shredded.

More than 26 million people have taken an at-home ancestry test. A bit of an update on the piece David Mittelman and I worked on last year, Consumer genomics will change your life, whether you get tested or not.

What ancient DNA tells us about caste. David Reich was in India for a bit talking about his work. It seems that they’re ready to uncoil their work soon enough. I’ve been told that he said a draft of the paper was written, so it’s probably going through internal revisions with collaborators.

This Mediterranean diet study was hugely impactful. The science has fallen apart.

The Making of a DNA Detective CeCe Moore, an amateur genealogist turned professional, helps police crack decades-old cases.

If you are on Twitter, Thomas Chatterton Williams is worth following.

A journalist is tweeting out old, and likely false, information, and another journalist is pointing out how you shouldn’t trust this result. Unfortunately, the original tweet-out is getting more RTs and likes than the refutation of the source and the credibility of the result.

I don’t normally read a book such as The Souls of Yellow Folk. First, it’s too much like a memoir, and I don’t care about other peoples’ memories. Second, I am on the same wavelength about most of these sorts of issues as Wes Yang, and I didn’t think I’d encounter anything novel or that pushed me to new views. But Yang is a good writer. Reading on the strong recommendation of a friend.

This week on the BrownCast I’ll be posting a conversation about Native Americans and nationalism with a lawyer.

Noah Smith says replace listening to podcasts with audiobooks. The problem I see with this is when it comes to books I have to give singular attention…so if I wanted to pay attention I’d just read the book. Podcasts are things that are less dense and contingent and I can sample in and out.

New York Did Us All a Favor by Standing Up to Amazon: Yes, Amazon’s departure will modestly hurt the city’s economy. But it’s also a victory against bad economic policy.

The Valentine’s Day episode of The Insight was fun. This was a conversation we could have had for three hours.

Speaking of academics who are irascible, Bob Trivers is burning up Twitter. Worth a follow.

Probably the easiest way to keep up the podcast since we don’t have a regular schedule is to subscribe at one of the links above. You can also support the podcast as a patron (the primary benefit now is that you get the podcasts considerably earlier than everyone else…this podcast has been up for nearly a week on the patron page).
