The method of psychology must be objective, even when studying subjective phenomena.

Civilization will not last, freedom will not survive, peace will not be kept, unless a very large majority of the people unite to defend them.

Books are the mirrors of the soul.

The habit of committing far more time to learning and thinking than to doing is no accident.

我们需要做的是始终面向未来；当你周围的世界发生变化，当变化对你不利时——曾经的顺风变成了逆风——你必须迎难而上，想办法应对，因为抱怨不是一种策略。
