Happiness serves hardly any other purpose than to make unhappiness possible.

There is probably not one person, however great his virtue, who cannot be led by the complexities of life's circumstances to a familiarity with the vices he condemns the most vehemently--without his completely recognizing this vice which, disguised as certain events, touches him and wounds him: strange words, an inexplicable attitude, on a given night, of the person whom he otherwise has so many reasons to love.

The facts of life do not penetrate to the sphere in which our beliefs are cherished; they did not engender those beliefs, and they are powerless to destroy them.

According to a charming law of nature which is evident even in the most sophisticated societies, we live in complete ignorance of whatever we love.

The bonds between ourselves and another person exists only in our minds. Memory as it grows fainter loosens them, and notwithstanding the illusion by which we want to be duped and which, out of love, friendship, politeness, deference, duty, we dupe other people, we exist alone. Man is the creature who cannot escape from himself, who knows other people only in himself, and when he asserts the contrary, he is lying.

A certain similarity exists, although the type evolves, between all the women we love, a similarity that is due to the fixity of our own temperament, which it is that chooses them, eliminating all those who would not be at once our opposite and our complement, fitted that is to say to gratify our senses and to wring our heart.

Always try to keep a patch of sky above your life.
