The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them: that's the essence of inhumanity.

The stranger is close to us, insofar as we feel between him and ourselves common features of a national, social, occupational, or generally human, nature. He is far from us, insofar as these common features extend beyond him or us, and connect us only because they connect a great many people.

Only two things in this world so that our souls are deeply shocked First, our brilliant stars overhead, First,our hearts loft y moral laws.

不要走别人走过的路，去走没人走过的路并留下足迹。

人性中的道德感是一种义务，而我们则必须赋予灵魂以美感。
