"Science fiction is the realism of our time."

詩人的話語是他們靈魂的回聲。

The only thing necessary for the triumph of evil is for good men to do nothing.

As to the gods, I do not know whether they exist or not, nor what they are like in form; for there are many things that hinder sure knowledge, the obscurity of the matter and the shortness of human life.

自信來自于準備充分并精通自己的領域。

The world is a book, and those who do not travel read only one page.

我們在實現同情、利他和愛的人類潛能方面還有很長的路要走。
