...Je n’ai pas cessé de l’être si c’est d’être jeune que d’aimer toujours !... L’humanité n’est pas un vain mot. Notre vie est faite d’amour, et ne plus aimer c’est ne plus vivre." (I have never ceased to be young, if being young is always loving... Humanity is not a vain word. Our life is made of love, and to love no longer is to live no longer.)

You see what stupid folk my publishers are; but they are all alike.

All your trouble comes from lack of exercise. A man of your strength and constitution ought always to have kept physically active. So don't jibe at the very wise advice that sentences you to one hour's walk a day. You imagine the work of the mind takes place only in the brain; but you're much mistaken. It takes place in the legs as well.

It is love, not faith, that moves mountains.

We must love stupid people better than ourselves; are they not the really unfortunate ones of this world? Do not people without taste and without ideal grow constantly weary, rejoicing in nothing, and being quite useless here below?

Lying, like license, has its degrees.

I needn't tell you that success and failure prove nothing - the whole thing is a lottery. It's pleasant to succeed; but for a philosophic mind it oughtn't to be very upsetting to fail.
