I'm afraid for all those who'll have the bread snatched from their mouths by these machines. What business has science and capitalism got, bringing all these new inventions into the works, before society has produced a generation educated up to using them!

In the decisive moment I won the victory over myself. I chose to live. And believe me, it takes courage to choose life under those circumstances.

Happiness is above all things the calm, glad certainty of innocence.

Happiness is worth a daring deed; we are both free if we but will it, and then the game is won.

In your power, all the same. Subject to your will and your demands. No longer free! No! That's a thought I'll never endure! Never.

Almost everyone who has gone to the bad early in life has had a deceitful mother.

But a scientific man must live in a little bit of style.
