sigmund Freud

“Dreams are not to be likened to the unregulated sounds that rise from a musical instrument struck by the blow of some external force instead of a player's hand; they are not meaningless, they are not absurd; ...they can be inserted into the chain of intelligible waking mental acts; they are constructed by a highly complicated activity of the mind.”

“Everything seemed to connect up, the whole worked well together, and one had the impression that the thing was really a machine and would soon go by itself... all that was perfectly clear, and still is.”

“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.”

“Man's judgments of value follow directly his wishes for happiness--they are an attempt to support his illusions with arguments.”

“Not to know the past is to be in bondage to it, while to remember, to know, is to be set free.”

“The inclination to aggression... constitutes the greatest impediment to civilization.”
