I know at last what distinguishes man from animals; financial worries.

I find war detestable but those who praise it without participating in it even more so.

To understand everything is to hate nothing.

Each man must learn his own ideal and try to accomplish it: that is a surer way of progress than to take the ideas of another.

Most men are essentially dead by thirty.

Love of my country does not demand that I shall hate and slay those noble and faithful souls who also love theirs.

There is only one heroism in the world: to see the world as it is, and to love it.
