充分发挥人的天性禀赋，发挥得越多越好：运用天性去穷究物理，极尽智力，通达自然，思惟神妙，造就豁达的胸怀和高洁的品德；尽量压抑人的情感欲望，遏制到越少越好：管束自己去谨慎说话，持重办事，约束自身，心地高洁，还要节衣缩食并减少情欲和嗜好。

The only limit to our realization of tomorrow will be our doubts of today.

Without patience, you cannot learn anything.

The only thing we have to fear is fear itself.

臣下都不说真话，君王隐蔽的过错就多。
