Nature never deceives us; it is we who deceive ourselves.
All through life a man has need of a counsellor and guide.
The French, for example, are a contemptible nation.
We are born, so to speak, twice over; born into existence, and born into life; born a human being, and born a man.
Provided a man is not mad, he can be cured of every folly but vanity.
Our greatest misfortunes come to us from ourselves.
