People are warmly invited to join a core conversation, which is an online meeting about an interesting text in the fields of history, philosophy, literature, or science. The first excellent contribution is by Roosevelt Montás (Columbia University) about Frederick Douglass’ What to a Slave is the Fourth of July? A core conversation starts out with an introductory video, and follows a few days later with an interactive online seminar. See Send me an email ( if you want to join the upcoming conversations!
