未经审视的生活不值得过”——苏格拉底审视的生活将哲学从学术期刊和课堂中拉出来，并把它重新搬上街头。长期以来，哲学家在直接与外部世界接触时，而不是孤立地与外部世界接触时，都做了最好的思考。苏格拉底在雅典集市上巡回演出，向当局挑麻烦。卢梭在印刷页上使他在大自然中的漫步永垂不朽。尼采曾经说过，只有在行走时构思的想法才有价值。

The first step towards philosophy is incredulity. —— Diderot(狄德罗，1713-1784，法国哲学家）

It’s been very devastating, this craving for meaning, though it’s something with which we are in constant negotiation. Everyone wants something like meaning. To leave things open and radically inappropriable and admitting we haven’t really understood is much less satisfying, more frustrating, and more necessary, I think.

I think we have moral obligations to help just as we have moral obligations as not to harm.
