Who shows up at the lectures?
Anyone and everyone. Most of our members have at least had one philosophy class in college and many have had quite a few or do reading on their own. The audience has a diverse set of experiences. Some of our members have post graduate degrees so the audience is quite varied. The point is that anyone with an interest in philosophy is welcome. Many times professors or people with expertise in the topic discussed are in the audience which makes for lively and interesting discussion.
