Conquering any difficulty always gives one a secret joy, for it means pushing back a boundary-line and adding to one's liberty.

Mutual respect implies discretion and reserve even in love itself; it means preserving as much liberty as possible to those whose life we share. We must distrust our instinct of intervention, for the desire to make one's own will prevail is often disguised under the mask of solicitude.

Doing easily what others find difficult is talent; doing what is impossible for talent is genius.

A man only understands what is akin to something already existing in himself.

Man is a willful and covetous animal, who makes use of his intellect to satisfy his inclinations, but who cares nothing for truth, who rebels against personal discipline, who hates disinterested thought and the idea of self-education. Wisdom offends him, because it rouses in him disturbance and confusion, and because he will not see himself as he is.

A journal takes the place of a confidant, that is, of friend or wife; it becomes a substitute for production, a substitute for country and public. It is a grief-cheating device, a mode of escape and withdrawal; but, factotum as it is, though it takes the place of everything, properly speaking it represents nothing at all.

Analysis kills spontaneity. The grain once ground into flour springs and germinates no more.
