I just wish this social institution [religion] wasn't based on what appears to me to be a monumental hoax built on an accumulation of customs and myths directed toward proving something that isn't true.
Customs do not concern themselves with right or wrong or reason. But they have to be obeyed; one reasons all around them until he is tired, but he must not transgress them, it is sternly forbidden.
Customs tell a man who he is, where he belongs, what he must do. Better illogical customs than none; men cannot live together without them. From an anthropologist's view, 'justice' is a search for workable customs.
[H]e is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
