我步入丛林，因为我希望生活有意义，我希望活得深刻，吸取生命中所有精华，把非生命的一切都击溃，以免当我生命终结，发现自己从没有活过。
I went to the woods because I wanted to live deliberately,I wanted to live deep and suck out all the marrow of life, To put to rout all that was not life, and not when I had come to die, Discover that I had not lived.
幸福是一种内在的工作。
一如灵魂和理性相互依存。
现在如果天下的人都相信鬼神能赏贤罚暴，那么天下怎么还会混乱！
Well, the first rule is that you can’t really know anything if you just remember isolated facts and try and bang ’em back. If the facts don’t hang together on a latticework of theory, you don’t have them in a usable form.
