17 - Caspar Oesterheld on evidential cooperation in large worlds (ECL)

In this episode, I chat with Caspar Oesterheld about a relatively simple application of weird decision theory: evidential cooperation in large worlds, or ECL for short. The tl;dr is you think there's at least some small probability of a very large multiverse, so you try to follow something closer to the average of all the values of civilizations in that multiverse that think like you, and therefore 'make it more likely' (in an evidential way) that those other civilizations do things that you like.

16 - Alessandro on learning Latin and Greek

In this episode, I chat with Alessandro (@polisisti [https://x.com/polisisti/] on X/Twitter) about our respective experiences learning Latin (and in his case ancient Greek). The Ranieri-Roberts approach to learning ancient Greek: https://www.youtube.com/watch?v=2vwb1wVzPec [https://www.youtube.com/watch?v=2vwb1wVzPec] We need to talk about Latinitas: https://foundinantiquity.com/2024/04/15/we-need-to-talk-about-latinitas/ [https://foundinantiquity.com/2024/04/15/we-need-to-talk-about-latinitas/] Legentibus: https://legentibus.com/ [https://legentibus.com/] Intermediate-level Greek texts: There is a good series called "Reading Greek" published by the Joint Association of Classics Teachers. An example volume is "The Intellectual Revolution: Selections from Euripides, Thucydides and Plato". Intermediate-level Latin texts: The reader Alessandro used in his second-year course was the "Oxford Latin Reader", edited by Maurice Balme and James Morwood. However, Alessandro prefers "Wheelock's Latin Reader: Selections from Latin Literature", edited by Richard A. LaFleur. Carmina Burana is a collection of poems that is fairly easy and very fun to read. An anthology of medieval Latin texts that Alessandro greatly enjoys is "Reading Medieval Latin" by Keith Sidwell. Many of these selections are of intermediate difficulty (a few are very hard). The prose works of Seneca bridge the gap between intermediate and advanced. Dictionaries and grammars: Alessandro's favourite Latin dictionary: The "Oxford Latin Dictionary" For medieval Latin: "Dictionary of Medieval Latin from British Sources" * the DMLBS is freely searchable at https://logeion.uchicago.edu [https://logeion.uchicago.edu] For advanced Latin grammar: "A New Latin Syntax" by E.C. Woodcock Alessandro's favourite Greek dictionary: The "Cambridge Greek Lexicon" "The Greek Particles" by John Dewar Denniston is the book that's very helpful for reading Plato.

14 - The 2024 Eclipse

In this episode, I give you updates from my trip with friends to see the 2024 total solar eclipse. Questions answered include: - Why are we bothering to go see it? - How many of us will fail to make it to the eclipse? - Does it actually get darker during a total solar eclipse, or is that just an optical illusion? - What moral dilemma will we face, and what will we do? - Whose lav mic will mysteriously fail to work during their interview?
