"The entire revolutionary movement necessarily finds both its empirical and its theoretical basis in the movement of private property – more precisely, in that of the economy. This material, immediately perceptible private property is the material perceptible expression of estranged human life. Its movement – production and consumption – is the perceptible revelation of the movement of all production until now, i.e., the realisation or the reality of man. Religion, family, state, law, morality, science, art, etc., are only particular modes of production, and fall under its general law. The positive transcendence of private property as the appropriation of human life, is therefore the positive transcendence of all estrangement – that is to say, the return of man from religion, family, state, etc., to his human, i.e., social, existence. Religious estrangement as such occurs only in the realm of consciousness, of man's inner life, but economic estrangement is that of real life; its transcendence therefore embraces both aspects. It is evident that the initial stage of the movement amongst the various peoples depends on whether the true recognised life of the people manifests itself more in consciousness or in the external world – is more ideal or real. Communism begins where atheism begins (Owen), but atheism is at the outset still far from being communism; indeed it is still for the most part an abstraction. The philanthropy of atheism is therefore at first only philosophical, abstract philanthropy, and that of communism is at once real and directly bent on action."
