“No other technique for the conduct of life attaches the individual so firmly to reality as laying emphasis on work; for his work at least gives him a secure place in a portion of reality, in the human community. The possibility it offers of displacing a large amount of libidinal components, whether narcissistic, aggressive or even erotic, on to professional work and on to the human relations connected with it lends it a value by no means second to what it enjoys as something indispensible to the preservation and justification of existence in society. Professional activity is a source of special satisfaction if it is a freely chosen one — if, that is to say, by means of sublimation, it makes possible the use of existing inclinations, of persisting or constitutionally reinforced instinctual impulses. And yet, as a path to happiness, work is not highly prized by men. They do not strive after it as they do after other possibilities of satisfaction. The great majority of people only work under the stress of necessity, and this natural human aversion to work raises most difficult social problems.”

Indeed, it also takes the liberty of representing some random element by its wished-for opposite, so that at first one cannot tell which of the possible poles is meant positively or negatively in the dream-thoughts.”

“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.”
