幸福源自内心的平静。

A man's character is his fate.

我们不是在创造物体，而是在创造场所。

As to the gods, I have no means of knowing either that they exist or that they do not exist. For many are the obstacles that impede knowledge, both the obscurity of the question and the shortness of human life.

我们这个时代最大的挑战不是技术上的，而是伦理上的。
