Religion is a prehistoric science...
Sigmund Freud, Austrian physician and pioneer psychoanalyst (1856-1939).
"It would be very nice if there were a God who created the world and was a benevolent providence, and if there were a moral order in the universe and an after-life; but it is a very striking fact that all this is exactly as we are bound to wish it to be."
"In the long run, nothing can withstand reason and experience, and the contradiction religion offers to both is palpable."
"The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life."
Freud certainly regarded belief in God as an illusion that mature men and women should lay aside. The idea of God was not a lie but a device of the unconscious which needed to be decoded by psychology. A personal god was nothing more than an exalted father-figure: desire for such a deity sprang from infantile yearnings for a powerful, protective father, for justice and fairness and for life to go on forever. God is simply a projection of these desires, feared and worshipped by human beings out of an abiding sense of helplessness. Religion belonged to the infancy of the human race; it had been a necessary stage in the transition from childhood to maturity. It had promoted ethical values which were essential to society. Now that humanity had come of age, however, it should be left behind. [A History of God]
Albert Einstein, German born American threoretical physicist (1879-1955).
"It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it." [From a letter Einstein wrote in English, dated 24 March 1954. It is included in Albert Einstein: The Human Side, edited by Helen Dukas and Banesh Hoffman, published by Princeton University Press.
If this being is omnipotent, then every occurrence, including every human action, every human thought, and every human feeling and aspiration is also His work; how is it possible to think of holding men responsible for their deeds and thoughts before such an almighty Being? In giving out punishment and rewards He would to a certain extent be passing judgment on Himself. How can this be combined with the goodness and righteousness ascribed to Him? [Albert Einstein, Out of My Later Years (New York: Philosophical Library, 1950), p. 27.]
During the youthful period of mankind's spiritual evolution, human fantasy created gods in man's own image who, by the operations of their will were supposed to determine, or at any rate influence, the phenomenal world... The idea of God in the religions taught at present is a sublimation of that old conception of the gods. Its anthropomorphic character is shown, for instance, by the fact that men appeal to the Divine Being in prayers and plead for the fulfillment of their wishes... In their struggle for the ethical good, teachers of religion must have the stature to give up the doctrine of a personal God, that is, give up that source of fear and hope which in the past placed such vase power in the hands of priests.
