我们都生活在一种受控的混乱状态中。

Certainty of evidence does not lead to certainty of belief.

I have to remind myself that some birds aren't meant to be caged. Their feathers are just too bright. And when they fly away, the part of you that knows it was a sin to lock them up DOES rejoice. Still, the place you live in is that much more drab and empty that they're gone. I guess I just miss my friend.

The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter.

抽象不仅仅是隐藏细节；它是关于创建问题域的清晰简洁的模型。
