“Our memory has no guarantees at all, and yet we bow more often than is objectively justified to the compulsion to believe what it says.”

“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.”

“It is that we are never so defenseless against suffering as when we love, never so helplessly unhappy as when we have lost our loved object or its love.”

“We need not deplore the renunciation of historical truth when we put forward rational grounds for the precepts of civilization. The truths contained in religious doctrines are after all so distorted and systematically disguised that the mass of humanity cannot recognize them as truth. The case is similar to what happens when we tell a child that new-born babies are brought by the stork. Here, too, we are telling the truth in symbolic clothing, for we know what the large bird signifies . But the child does not know it. He hears only the distorted part of what we say, and feels that he has been deceived; and we know how often his distrust of the grown-ups and his refractoriness actually take their start from this impression. We have become convinced that it is better to avoid such symbolic disguisings of the truth in what we tell children and not to withhold from them a knowledge of the true state of affairs commensurate with their intellectual level.”

“scientific knowledge has taught [humans] much since the days of the Deluge, and it will increase their power still further. And, as for the great necessities of Fate, against which there is no help, they will learn to endure them with resignation. Of what use to them is the mirage of wide acres in the moon, whose harvest no one has ever yet seen? As honest smallholders on this earth they will know how to cultivate their plot in such a way that it supports them. By withdrawing their expectations from the other world and concentrating all their liberated energies into their life on earth, they will probably succeed in achieving a state of things in which life will become tolerable for everyone and civilization no longer oppressive to anyone. Then, with one of our fellow-unbelievers, they will be able to say without regret: 'We leave Heaven to the angels and the sparrows.”

“We believe that it is possible for scientific work to gain some knowledge about the reality of the world, by means of which we can increase out power and in accordance with which we can arrange our life. If this belief is an illusion, then we are in the same position as you. But science has given us evidence by its numerous and important successes that it is no illusion.”

“Immorality, no less than morality, has at all times found support in religion.”
