Karl Marx,
Selected Essays — A Criticism Of The Hegelian Philosophy Of Right
(1926)
“ He who has only found a reflexion of himself in the fantastic reality of heaven where he looked for a superman, will no longer be willing to find only the semblance of himself, only the sub-human, where he seeks and ought to find his own reality.The foundation of the criticism of religion is: Man makes religion, religion does not make man. Religion indeed is man's self-consciousness and self-estimation while he has not found his feet in the universe. But Man is no abstract being, squatting outside the world. Man is the world of men, the State, society. ”
