——〈民权主义第五讲〉，1924年4月20日

To every action there is always opposed an equal reaction； or， the mutual actions of two bodies upon each other are always equal， and directed to contrary parts.

Friendship is a single soul dwelling in two bodies.

我相信去掌握其他人已经发现的最佳知识的纪律。

The secret to great baking lies in the details—timing, temperature, and technique.

你必须完整才能快乐。

人变得真正低劣时，除了高兴别人的不幸外，已无其他乐趣可言。

不冒险就无法创造未来。
