“It is impossible to escape the impression that people commonly use false standards of measurement — that they seek power, success and wealth for themselves and admire them in others, and that they underestimate what is of true value in life.”

Sigmund Freud book Civilization and Its Discontents

Man kann sich des Eindrucks nicht erwehren, daß die Menschen gemeinhin mit falschen Maßstäben messen, Macht, Erfolg und Reichtum für sich anstreben und bei anderen bewundern, die wahren Werte des Lebens aber unterschätzen.

“Illusions commend themselves to us because they save us pain and allow us to enjoy pleasure instead. We must therefore accept it without complaint when they sometimes collide with a bit of reality against which they are dashed to pieces.”

“The unconscious is the larger circle which includes within itself the smaller circle of the conscious; everything conscious has its preliminary step in the unconscious, whereas the unconscious may stop with this step and still claim full value as a psychic activity. Properly speaking, the unconscious is the real psychic; its inner nature is just as unknown to us as the reality of the external world, and it is just as imperfectly reported to us through the data of consciousness as is the external world through the indications of our sensory organs.”
