All books are divided into two classes, the books of the hour, and the books of all time.
所有的书都可以分为两类，一类是一时之书，一类是永久之书。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
The only thing that permits human beings to collaborate with one another in a truly open-ended way is their willingness to have their beliefs modified by new facts. Only openness to evidence and argument will secure a common world for us.
唯一允许人类以一种真正开放的方式彼此合作的是他们愿意让自己的信念被新的事实所改变。只有对证据和论点持开放态度，我们才能建立一个共同的世界。
It is a good thing to learn caution from the misfortunes of others.
从别人的不幸中学会谨慎是一件好事。
