I think that the most important thing is to be honest with yourself and with your audience.

我们必须始终质疑我们的假设，并愿意根据新的证据修订我们的理论。

一件事不一定是真的或假的；它可能既是真的又是假的。

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

People are not lazy. They simply have impotent goals – that is, goals that do not inspire them.

【原文】樊迟问知，子曰：“务民之义，敬鬼神而远之，可谓知矣。”问仁，曰：“仁者先难而后获，可谓仁矣。”【译文】樊迟问怎样才是“智”，孔子说：“专心致力于（提倡）老百姓应该遵从的道德，尊敬鬼神但要远离它，就可以说是智了。”樊迟又问怎样才是仁，孔子说：“仁人对难做的事，做在人前面，有收获的结果，他得在人后，这可以说是仁了。”
