Freedom does not consist in any dreamt-of independence from natural laws, but in the knowledge of these laws, and in the possibility this gives of systematically making them work towards definite ends.
Friedrich EngelsJust as Marx used to say about the French Marxists of the late 'seventies: All I know is that I am not a Marxist.
Friedrich EngelsThe proletariat uses the State not in the interests of freedom but in order to hold down its adversaries, and as soon as it becomes possible to speak of freedom the State as such ceases to exist.
Friedrich EngelsThus at every step we are reminded that we by no means rule over nature like a conqueror over a foreign people, like someone standing outside nature - but that we, with flesh, blood and brain, belong to nature, and exist in its midst, and that all our mastery of it consists in the fact that we have the advantage over all other creatures of being able to learn its laws and apply them correctly.
Friedrich Engels
