The Thinkers are the oldest SL's in-world philosophy group, very loosely discussing all sorts of stuff — from religion to magic, from science to SL — in a model not unlike the Plato's Academy. Originally founded by Jinny Fonzarelli, the group has grown to about 238 members (Jan 2006) by inviting attendees to their regular events, meets for about an hour several times a week, traditionally in Euro-friendly hours (around 2-4 PM PST).
