我们男人要是娶到了应得的女人，日子可就难过了。

I used to think the world was broken down by tribes. Then I thought it was broken down by rich and poor. Then I thought it was broken down by stupid and smart. But I know now that it is broken down by people who are alive and people who are dead.

The natural and moral world is the two-fold object of man's rational care.

I love to think of nature as an unlimited broadcasting station, through which God speaks to us every hour, if we will only tune in.

Show me the incentive and I will show you the outcome.
