Abstract
Why does so much famous philosophy come out of classical Greece? Actually, the answer derives from two accidents of geography—1) the smoothness of the Mediterranean Sea, which facilitated ancient trade, and 2) the multitude of mountains and islands in Greece, which made the classical city-states small. From these two geographical accidents flow most of the special features of classical Greek thought. This thesis is also defended in chapter 7 of The Questions of Moral Philosophy and in chapters 1 and 2 of If A, Then B: How the World Discovered Logic.
