To know oneself, one should assert oneself.

Against eternal injustice, man must assert justice, and to protest against the universe of grief, he must create happiness.

To abandon oneself to principles is really to die - and to die for an impossible love which is the contrary of love.

At 30 a man should know himself like the palm of his hand, know the exact number of his defects and qualities, know how far he can go, foretell his failures - be what he is. And, above all, accept these things.

Why should it be essential to love rarely in order to love much?

I should like to be able to love my country and still love justice.
