The Thucydidean Slip On Mark Carney's speech in Davos, Thucydides, and the repressed tension between justice and necessity

Something has been bugging me about the much-praised Mark Carney's speech in Davos. And given that I've been reading legal/political speeches with my students, I decided to try to figure out what exactly bothered me about Carney's speech. open.substack.com/pub/rtall/p/...

Yesterday, I had the pleasure to speak with David Wakeling, Global Head of the AI Group at A&O Shearman, in front of an audience of HLS faculty and students.

We talked about how associates use AI, the future of Big Law and law schools...

On the lax standards at Harvard, 1866:

"Harvard Law School at the time had ... no examinations: its only requirement... was periodic attendance at lectures... [Oliver Wendell] Holmes stopped doing even that... Harvard still awarded him a degree" [G. Eward White 2009]

New working paper (with Kenneth Khoo) on the controversial Delaware corporate law reform (SB 21). We examine the market reaction to SB 21 through a series of event studies and we find that the market thinks the new rules are bad for investors.

I haven’t visited Henry in a whileβ€”five or six months. Sorry, Henry. But he’s doing wellβ€”just a bit grumpy these days. β€œMen talk of freedom! How many are free to think? free from fear, from perturbation, from prejudice?”

Yes! It's the light warning about the next tunnel. But congratulations on this well-deserved end of one tunnel!

I don't know anything anymore about films, but I can't forget the epiphany of watching this when it came out, in a small theater in Rome, in Via delle Quattro Fontane. Lynch was pure, absolute cinema. www.youtube.com/watch?v=MTYz...

In one of my previous lives I was in love with cinema. I went to festivals and wrote reviews and critical essays for independent webzines. And it was mostly David Lynch's fault.

I like the debate on whether today's economists should read old economists, but a more interesting one is whether generals should travel to the battlefield with a small library of classics

If I had to found a new religion, it would be entirely based on Moby Dick. Its scripture would be the novel itself and its theologians would write endless commentaries on the moral, spiritual, and existential implications of random quotes of the Moby Dick bot

Many people don’t like the idea of a literary canon. I do like it, but if the editor of the NYT Book Review doesn’t read the canon, (sadly) there is no canon.

Then, if the topic permits, you should start with a β€œfunny story.” Or, if the topic is too serious for this, with something sad, new, or terrible. Because, when one has already eaten too much, you refresh their appetite by giving them something bitterish or something sweet.

Fourth, sometimes readers are fatigued even before starting to read, like when you are trying to contribute to an already huge literature. In this case, you β€œshould promise to speak more briefly than you were prepared to speak.”

And how do you show that the issues are important? If they concern all humanity, that particular audience, the interests of the republic, some illustrious people (yes, this applies to academic papers), or the immortal gods (this, unfortunately, doesn’t apply).

Third, there’s only one way to win the reader’s attention: show that the things you are going to say are important, novel, and incredible (magna, nova, incredibilia). Well, they don’t need to be truly β€œincredible” in our line of business, but they shouldn’t be obvious.

Uncertain cases (anceps genus causae): These are cases on which reasonable people disagree. The introduction should immediately tackle the disputed question.

Complicated cases (obscurum genere causae): If the issues are difficult to grasp, you should make the reader receptive by presenting an outline of the case (summam causae) briefly and in plain language (aperte et breviter).

Modest cases (humile genus causae): When the reader is likely to treat the topic dismissively, you must first explain why the issue is important and make the reader pay attention.
