The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is, indeed, the self-consciousness and self-esteem of man who has either not yet won through to himself, or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world...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.
Night after night on starry wingsNight lovers soared so highMiles apart, across the oceansTheir love forgot to sighIn heavenly flight’s timelessnessThat highest height treasuredInto the deepest of all bluesTheir depth of love measured.From the poem 'The Ballad of Night Lovers
I want to do what little I can to make my country truly free, to broaden the intellectual horizon of our people, to destroy the prejudices born of ignorance and fear, to do away with the blind worship of the ignoble past, with the idea that all the great and good are dead, that the living are totally depraved, that all pleasures are sins, that sighs and groans are alone pleasing to God, that thought is dangerous, that intellectual courage is a crime, that cowardice is a virtue, that a certain belief is necessary to secure salvation, that to carry a cross in this world will give us a palm in the next, and that we must allow some priest to be the pilot of our souls.
