“We may insist as often as we like that man's intellect is powerless in comparison to his instinctual life, and we may be right in this. Nevertheless, there is something peculiar about this weakness. The voice of the intellect is a soft one, but it will not rest until it has gained a hearing. Finally, after a countless succession of rebuffs, it succeeds.”

“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.”

“The freeing of an individual, as he grows up, from the authority of his parents is one of the most necessary though one of the most painful results brought about by the course of his development. It is quite essential that that liberation should occur and it may be presumed that it has been to some extent achieved by everyone who has reached a normal state. Indeed, the whole progress of society rests upon the opposition between successive generations. On the other hand, there is a class of neurotics whose condition is recognizably determined by their having failed in this task.”

“And it is only after seeing man as his unconscious, revealed by his dreams, presents him to us that we shall understand him fully. For as Freud said to Putnam: "We are what we are because we have been what we have been.”

“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.”

“He that has eyes to see and ears to hear may convince himself that no mortal can keep a secret. If his lips are silent, he chatters with his fingertips; betrayal oozes out of him at every pore.”

“We are so constituted that we can gain intense pleasure only from the contrast, and only very little from the condition itself.”
