清白是自己的辩护。

要理解心理学，就要在自然环境中观察行为。

The man who believes that the secrets of the world are forever hidden lives in mystery and fear. Superstition will drag him down. The rain will erode the deeds of his life. But that man who sets himself the task of singling out the thread of order from the tapestry will by the decision alone have taken charge of the world and it is only by such taking charge that he will effect a way to dictate the terms of his own fate.

如果你愿意，可以错误地思考，但在任何情况下都要为自己思考。

The study of mind is the study of adaptive behavior.

制度主义者……往往自以为非常聪明；他常常如此迷恋于自己设想的政府理想计划的所谓完美，以至于不能容忍对其有丝毫的偏离。

创新不仅仅是技术问题；它关乎改变思维方式并拥抱新的思考方式。
