"Books are the maps that guide us through life."

创新不仅仅是关于新想法，而是让它们发挥作用。

"Psychology must focus on the utility of mental operations."

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

自然是一个活生生的整体，而非死寂的集合体。
