I recently discovered David Morgan Mar’s fun blog 100 Proofs that the Earth is a Globe. He’s adding things over time, so he’s only up to 42 proofs so far.
I browsed the site looking for a proof that I know from Copernicus. It figures in debates about underdetermination, and it’s a stock example I give to students to illustrate the Duhem-Quine problem.

I have a book called Values and the Future on my shelf which I take down and read short passages from occasionally. In one article, Theodore J. Gordon offers “Forecasts of certain technological developments and their potential social consequences” from his vantage point in 1969. The prospect of wide-band communication systems suggests these possible consequences for education:
Ready and cheap availability of excellent curricula… might make education a respected and common pastime.
Canned lectures by eminent professors may make TV teaching superior to that in resident institutions.
University degrees will be extended to viewers who complete their courses solely on TV. Residency requirements may disappear.
Reading an interview with Mark Johnston, I learned a fact that I can’t believe I didn’t know before: As a student, Immanuel Kant made money as a pool shark. Johnston gives this extended quote from one of Kant’s university friends:

Kant’s only recreation was playing billiards… [He] had nearly perfected [his] game, and rarely returned home without some winnings. As a consequence, persons refused to play with [him], and [he] abandoned this source of income, and chose instead L’Hombre, which he played well.
This is a post I wrote back in November but for some reason didn’t post. I had learned from a then-recent episode of Citation Needed about Juan Pujol, a Spaniard who served as a double agent in WW II.
The beginning of Pujol’s career as a spy vexes the usual connotation of “double agent.” He wanted to help the Allied cause, but the British repeatedly declined his offer. So he reached out to the Nazis and offered to help them, with no intention of doing so. Instead of going to the UK and reporting back to the Nazis, he went to Portugal and lied to the Nazis about what was going on in the UK. He made up a network of contacts and things that he had learned from them. He bodged together these reports based on reference books and magazines.
British intelligence became aware of these reports going to Berlin and tried to track down this mysterious agent. Pujol was finally able to convince them of his usefulness, and they brought him to London. There he worked to create a whole fictional network of spies who systematically misled Nazi intelligence about things in the lead up to D-Day.
Clearly Pujol was a double agent in the latter part of the story, but what kind of agent was he in the first part? It would be wrong to say flat-footedly that he was a Nazi agent, because he was deliberately sending them rubbish. But he wasn’t coordinating with the British, either. Because he wasn’t a British agent, he lacked the second agency required for being a double agent.
I’ve recently been reading about the ontological turn in anthropology. The movement so-called is little more than a decade old but has nevertheless generated an extensive literature.
