The most profound joy has more of gravity than of gaiety in it.

A good marriage would be between a blind wife and a deaf husband.

Who does not see that I have taken a road along which I shall go, without stopping and without effort, as long as there is ink and paper in the world? I cannot keep a record of my life by my actions; fortune places them too low. I keep it by my thoughts.

I, who am king of the matter I treat, and who owe an accounting for it to no one, do not for all that believe myself in all I write. I often hazard sallies of my mind which I mistrust.

If I am to serve as an instrument of deceit, at least let it be with a clear conscience. I do not want to be considered either so affectionate or so loyal a servant as to be found fit to betray anyone.

He who lives not to others, lives little to himself.

The soul which has no fixed purpose in life is lost; to be everywhere, is to be nowhere.
