"The basis of irreligious criticism is: Man makes religion, religion does not make man. Religion is the self-consciousness and self-esteem of man who has either not yet found himself or has already lost himself again. But man is no abstract being encamped outside the world. Man is the world of man, the state, society. This state, this society, produce religion, an inverted world-consciousness, because they are an inverted 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 complement, its universal source of consolation and justification. It is the fantastic realisation of the human essence because the human essence has no true reality. The struggle against religion is therefore indirectly a fight against the world of which religion is the spiritual aroma. Religious distress is at the same time the expression of real distress and also 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 spiritless conditions. It is the opium of the people."
Marx, Contribution To The Critique Of Hegel’s Philosophy Of Right
Look at what an incredible writer Marx is! What an unfortunate truncation it is to reduce his opinion on religion to “the opiate of the masses.”(via towerofsleep)
