“The basis of irreligious criticism is: Man makes religion, religion does not make man. In other words, religion is the self-consciousness and self-feeling of man who has either not yet found himself or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man, the state, society. This state, this society, produce religion, a reversed world-consciousness, because they are a reversed world. Religion is the general theory of that world, its encyclopaedic compendium, its logic in a popular form, its spiritualistic point d’honneur, its enthusiasm, its moral sanction, its solemn completion, its universal ground for consolation and justification. It is the fantastic realization of the human essence because the human essence has no true reality. The struggle against religion is therefore mediately the fight against the other world, of which religion is the spiritual aroma.
Religious distress is at the same time the expression of real distress and the protest against real distress. Religion is the sigh of the oppressed creature, the heart of a heartless world, just as it is the spirit of a spiritless situation. It is the opium of the people.
The abolition of religion as the illusory happiness of the people is required for their real happiness. The demand to give up the illusions about its condition is the demand to give up a condition which needs illusions. The criticism of religion is therefore in embryo the criticism of the vale of woe, the halo of which is religion.
Criticism has plucked the imaginary flowers from the chain not so that man will wear the chain without any fantasy or consolation but so that he will shake off the chain and cull the living flower. The criticism of religion disillusions man to make him think and act and shape his reality like a man who has been disillusioned and has come to reason, so that he will revolve round himself and therefore round his true sun. Religion is only the illusory sun which revolves round man as long as he does not revolve around himself.”
