The world belongs to who doesn't feel. The primary condition to be a practical man is the absence of sensitivity.

When all by myself, I can think of all kinds of clever remarks, quick comebacks to what no one said, and flashes of witty sociability with nobody. But all of this vanishes when I face someone in the flesh: I lose my intelligence, I can no longer speak, and after half an hour I just feel tired. Talking to people makes me feel like sleeping. Only my ghostly and imaginary friends, only the conversations I have in my dreams, are genuinely real and substantial.

My boredom with everything has numbed me.

Again I see you, But me I don't see!, The magical mirror in which I saw myself has been broken, And only a piece of me I see in each fatal fragment - Only a piece of you and me!

There's no greater tragedy than an equal intensity, in the same soul or the same man, of the intellectual sentiment and the moral sentiment. For a man to be utterly and absolutely moral, he has to be a bit stupid. For a man to be absolutely intellectual, he has to be a bit immoral.

The abstract intelligence produces a fatigue that's the worst of all fatigues. It doesn't weigh on us like bodily fatigue, nor disconcert like the fatigue of emotional experience. It's the weight of our consciousness of the world, a shortness of breath in our soul.

Life is whatever we conceive it to be.
