“Experience teaches that for most people there is a limit beyond which their constitution cannot comply with the demands of civilization. All who wish to reach a higher standard than their constitution will allow, fall victims to neurosis. It would have been better for them if they could have remained less "perfect".”

“Religion is an attempt to get control over the sensory world, in which we are placed, by means of the wish-world, which we have developed inside us as a result of biological and psychological necessities. But it cannot achieve its end. Its doctrines carry with them the stamp of the times in which they originated, the ignorant childhood days of the human race. Its consolations deserve no trust. Experience teaches us that the world is not a nursery. The ethical commands, to which religion seeks to lend its weight, require some other foundations instead, for human society cannot do without them, and it is dangerous to link up obedience to them with religious belief. If one attempts to assign to religion its place in man’s evolution, it seems not so much to be a lasting acquisition, as a parallel to the neurosis which the civilized individual must pass through on his way from childhood to maturity.”

“Our possibilities of happiness are already restricted by our constitution. Unhappiness is much less difficult to experience. We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful to us than any other.”

“Dream's evanescence, the way in which, on awakening, our thoughts thrust it aside as something bizarre, and our reminiscences mutilating or rejecting it—all these and many other problems have for many hundred years demanded answers which up till now could never have been satisfactory.”

“What is common in all these dreams is obvious. They completely satisfy wishes excited during the day which remain unrealized. They are simply and undisguisedly realizations of wishes.”

“It would be an undoubted advantage if we were to leave God out altogether and honestly admit the purely human origin of all the regulations and precepts of civilization. Along with their pretended sanctity, these commandments and laws would lose their rigidity and unchangeableness as well. People could understand that they are made, not so much to rule them as, on the contrary, to serve their interests; and they would adopt a more friendly attitude to them, and instead of aiming at their abolition, would aim only at their improvement.”

“We tell ourselves how lovely it would be, would it not, if there were a God who created the universe and benign Providence, a moral world order, and life beyond the grave, yet it is very evident, is it not, that all of this is the way we should inevitably wish it to be. And it would be even more remarkable if our poor, ignorant bondsman ancestors had managed to solve all these difficult cosmic questions.”
