"The world begins at a kitchen table. No matter what, we must eat to live."

Freedom of men under government is to have a standing rule to live by, common to everyone, and not to be subject to the inconstant, uncertain, arbitrary will of another man.

The world is full of obvious things which nobody by any chance ever observes.

你不应该只是因为事物不同就做事情不同。他们需要更好。

科学不仅是理性的学科，也是浪漫和激情的学科。

坚持做自己喜欢的事，总有一天会被看见。
