科学不是形式逻辑——它需要思想的自由发挥，与其他任何创造性艺术一样。

A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.

不要把行动与进步混为一谈。

译文：不怕自身会产生恶念，只怕发觉自身的恶念太迟。

心灵不是一个物体，而是一个过程——一个不断变化的体验与适应的流动。

The most successful leaders are those who see leadership as a responsibility, not a privilege.
