Graham has another alt. history of philosophy post up that is perhaps even more interesting than those posted before. I have wondered since reading these thinkers years ago how our history would be different had more pre-Socratic writings survived.
I can’t even imagine what the Middle Ages would have looked like had there been a Heraclitean school or a Parmenidean school or any of the other monumental figures from that time. Medieval mysticism would certainly be more interesting! How would Christianity be different if Empedocles had been hot stuff back then? My imagination is running wild right now.
