History does nothing, possesses no enormous wealth, fights no battles. It is rather man, the real, living man, who does everything, possesses, fights. It is not History, as if she were a person apart, who uses men as a means to work out her purposes, but history itself is nothing but the activity of men pursuing their purposes.
Karl MarxThe fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.
Karl MarxThe ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force. The class which has the means of material production at its disposal, has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it. The ruling ideas are nothing more than the ideal expression of the dominant material relationships, the dominant material relationships grasped as ideas.
Karl MarxIn every revolution there intrude, at the side of its true agents, men of a different stamp; some of them survivors of and devotees to past revolutions, without insight into the present movement, but preserving popular influence by their known honesty and courage, or by the sheer force of tradition; others mere brawlers, who, by dint of repeating year after year the same set of stereotyped declamations against the government of the day, have sneaked into the reputation of revolutionists of the first water They are an unavoidable evil: with time they are shaken off.
