Here’s a lecture by Steve Smith from Yale University which kicks off with some additional juicy details re. Jean-Jacques’s life (Did you know he abandoned five of his kids to an orphanage? What a bastard!) and mentions a few specific points of influence beyond just hippies (also agrarian communist experimenters!) You can follow the links that appear after this clip ends to see the subsequent parts of the lecture, which presents the work we talked about on our episode.
Personally, I have a short attention span, and liked the fact that I could just move manually move the progress bar forward and read the caption to get through this video at twice its actual speed. Smith gets pretty into it eventually, however, and has some interesting things to say even if he just does read his lectures straight out of his notes (which always leads me to think, “why am I not just reading this myself?”).
