The method of psychology must be as exact as that of the physical sciences.

一个人学得越多，就越能看到还有多少东西需要学习。

No one will protect what they don't care about, and no one will care about what they have never experienced.

"Technique is important, but it should never overshadow the soul of the work."

真正的创新发生在必要性和创造力的交汇处。

在科学中，重要的不是获得新的事实，而是发现思考它们的新方法。
