A brain is a society of very small simple modules that cannot be said to be thinking that are not smart in themselves. But when you have a network of them together out of that arises a kind of smartness.
We are infected by our own misunderstanding of how our own minds work.
The whole system of society tells you what to do.
When you are offended at any man's fault turn to yourself and study your own failings. Then you will forget your anger.
