Optimism is an alienated form of faith, pessimism an alienated form of despair.

We try to evade the question of existence with property, prestige, power, possession, production, fun, and, ultimately, by trying to forget that we- that I- exist. No matter how much he thinks of God or goes to church, or how much he believes in religious ideas , if he, the whole man, is deaf to the question of existence, if he does not have an answer to it, he is marking time, and he lives and dies like one of the million things he produces. He thinks of God, instead of experiencing God.

Reason is man's faculty for grasping the world by thought, in contradiction to intelligence, which is man's ability to manipulate the world with the help of thought. Reason is man's instrument for arriving at the truth, intelligence is man's instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

Man today is fascinated by the possibility of buying, more, better, and especially, new things. He is consumption hungry... To buy the latest gadget, the latest model of anything that is on the market, is the dream of everybody, in comparison to which the real pleasure in use is quite secondary. Modern man, if the dared to be articulate about his concept of heaven, would describe a vision which would look like the biggest department store in the world.

Modern man is assailed on every side and almost without interruption by noise - of the radio, of television, of headlines, of advertising and of the cinema - of which the greatest part, far from enlightening the mind, blunts and stultifies it.

I feel worried, deeply worried, only about one thing - the possibility that we fall... that we cannot avoid an atomic war.

I would say, compared with the 19th century, compared with most previous history, this is as good or better a society than any which man has ever made. But that doesn't mean it is such a good one.
