Morrison I. Swift, Human Submission
This Cleveland workingman, killing his children and himself, is one of the elemental, stupendous facts of this modern world and of this universe. It cannot be glossed over or minimized away by all the treatises on God, and Love, and Being, helplessly existing in their haughty monumental vacuity. This is one of the simple irreducible elements of this world’s life after millions of years of divine opportunity and twenty centuries of Christ. It is in the moral world like atoms or sub-atoms in the physical, primary, indestructible. And what it blazons to man is the … imposture of all philosophy which does not see in such events the consummate factor of conscious experience. These facts invincibly prove religion a nullity. Man will not give religion two thousand centuries or twenty centuries more to try itself and waste human time; its time is up, its probation is ended. Its own record ends it. Mankind has not sons and eternities to spare for trying out discredited systems…
Karl Marx, A Contribution to the Critique of Hegel’s Philosophy of Right
Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.
The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.
Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of religion disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Religion is only the illusory Sun which revolves around man as long as he does not revolve around himself.
It is, therefore, the task of history, once the other-world of truth has vanished, to establish the truth of this world. It is the immediate task of philosophy, which is in the service of history, to unmask self-estrangement in its unholy forms once the holy form of human self-estrangement has been unmasked. Thus, the criticism of Heaven turns into the criticism of Earth, the criticism of religion into the criticism of law, and the criticism of theology into the criticism of politics.
