有了图书馆，你就是自由的，不受暂时政治气候的限制。它是最民主的机构，因为没有人——绝对没有人——能告诉你该读什么、什么时候读以及如何读。
With a library you are free, not confined by temporary political climates. It is the most democratic of institutions because no one - but no one at all - can tell you what to read and when and how.
悲伤不是线性的过程。它像波浪一样袭来，有时那些波浪会把你击倒。
Judge a man by his questions rather than by his answers.
In mathematics, the art of proposing a question must be held of higher value than solving it.
你所需要的越少，你就越自由。
