In a morbid condition of the brain, dreams often have a singular actuality, vividness, and extraordinary semblance of reality.

I am a sick man...I am a spiteful man. I am an unattractive man. I think my liver is diseased. Then again, I don't know a thing about my illness; I'm not even sure what hurts.

I don’t understand anything...and I no longer want to understand anything. I want to stick to the fact...If I wanted to understand something, I would immediately have to betray the fact, but I’ve made up my mind to stick to the fact.

Man is stupid, phenomenally stupid.

I have been tortured with longing to believe ... and the yearning grows stronger the more cogent the intellectual difficulties stand in the way.

A man who lies to himself, and believes his own lies becomes unable to recognize truth, either in himself or in anyone else, and he ends up losing respect for himself and for others. When he has no respect for anyone, he can no longer love, and, in order to divert himself, having no love in him, he yields to his impulses, indulges in the lowest forms of pleasure, and behaves in the end like an animal. And it all comes from lying - lying to others and to yourself.

It's a burden to us even to be human beings-men with our own real body and blood; we are ashamed of it, we think it a disgrace and try to contrive to be some sort of impossible generalized man.
