Three-quarters of the sicknesses of intelligent people come from their intelligence. They need at least a doctor who can understand this sickness.

There is not a woman in the world the possession of whom is as precious as that of the truths which she reveals to us by causing us to suffer.

Like many intellectuals, he was incapable of saying a simple thing in a simple way.

A person does not...stand motionless and clear before our eyes with his merits, his defects, his plans, his intentions with regard to ourself exposed on his surface...but is a shadow which we can never succeed in penetrating...a shadow behind which we can alternately imagine, with equal justification, that there burns the flame of hatred and of love.

Our intonations contain our philosophy of life, what each of us is constantly telling himself about things.

Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.

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.
