We live not alone but chained to a creature of a different kingdom: our body.

And so it is with our own past. It is a labour in vain to attempt to recapture it: all the efforts of our intellect must prove futile. The past is hidden somewhere outside the realm, beyond the reach of intellect, in some material object (in the sensation which that material object will give us) of which we have no inkling. And it depends on chance whether or not we come upon this object before we ourselves must die.

You can't learn the truth about a man's intentions by asking him.

We do not receive wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can make for us, which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world. The lives that you admire, the attitudes that seem noble to you, have not been shaped by a paterfamilias or a schoolmaster, they have sprung from very different beginnings, having been influenced by evil or commonplace that prevailed round them. They represent a struggle and a victory.

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

Our desires cut across one another, and in this confused existence it is rare for happiness to coincide with the desire that clamoured for it.

Pleasures are like photographs: in the presence of the person we love, we take only negatives, which we develop later, at home, when we have at our disposal once more our inner dark room, the door of which it is strictly forbidden to open while others are present.
