我们对明天的唯一限制是我们今天的疑虑。

We begin with the hypothesis that any subject can be taught effectively in some intellectually honest form to any child at any stage of development.

I do not like proper novels. In proper novels people say things like, ‘I am veined with iron, with silver and with streaks of common mud. I cannot contract into the firm fist which those clench who do not depend on stimulus.’ What does this mean? I do not know. Nor does Father. Nor do the people who write these books.

对我而言，独立就是幸福。我的祖国是世界，我信奉的宗教是行善，我的头脑是我自己的教堂。

你不能让恐惧支配你的生活。
