Nature is not a temple, but a workshop, and man's the workman in it.

Go forward while you can, but if your strength fails you, sit down near the road and gaze without anger or envy at those who pass by. They don't have far to go, either.

I believe love produces a certain flowering of the whole personality which nothing else can achieve.

I share no man's opinions; I have my own.

Most people can't understand how others can blow their noses differently than they do.

In my case there was no first love. I began with the second.

No matter how often you knock at nature's door, she won't answer in words you can understand--for Nature is dumb. She'll vibrate and moan like a violin, but you mustn't expect a song.
