——《在上海南京路同盟会机关的演说》（1912年4月16日）

My mind is my weapon. My brother has his sword, King Robert has his warhammer, and I have my mind... And a mind needs books as a sword needs a whetstone, if it is to keep its edge.

All my life through, the new sights of Nature made me rejoice like a child.

The most important thing in science is not to solve problems, but to ask the right questions.

你的太阳无法照耀是因为我。

人生就像一场逆行的旅程，我也是其中的一个过客。

重要的是不要停止提问。好奇心有其存在的理由。

文学的力量在于它使我们感到不那么孤独。
