Rest, nature, books, music...such is my idea of happiness.

There is no result in nature without a cause; understand the cause and you will have no need of the experiment.

I do not see why man should not be just as cruel as nature.

The natural thing to do is to work-to recognize that prosperity and happiness can be obtained only through honest effort. Human ills flow largely from attempting to escape from this natural course. I have no suggestion which goes beyond accepting in its fullest this principle of nature.

Nature does not complete things. She is chaotic. Man must finish, and he does so by making a garden and building a wall.

Nature knows no indecencies; man invents them.
