The Study of Cause and Effect

It is hard to have one's watch stolen, but one reflects that the thief of the watch became a thief from causes of heredity and environment which are as interesting as they are scientifically comprehensible; and one buys another watch, if not with joy, at any rate with a philosophy that makes bitterness impossible. One loses, in the study of cause and effect, that absurd air which so many people have of being always shocked and pained by the curiousness of life. Such people live amid human nature as if human nature were a foreign country full of awful foreign customs. But, having reached maturity, one ought surely to be ashamed of being a stranger in a strange land!
