Freedom is the recognition of necessity.

Competition permits the capitalist to deduct from the price of labour power that which the family earns from its own little garden or field; the workers are compelled to accept any piece wages offered to them, because otherwise they would get nothing at all, and they could not live from the products of their small-scale agriculture alone, and because, on the other hand, it is just this agriculture and landownership which chains them to the spot and prevents them from looking around for other employment.

Freedom is the recognition of necessity.

The free development of each is the condition for the free development of all.

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.

Thus 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.

All history has been a history of class struggles, of struggles between exploited and exploiting, between dominated and dominating classes at various stages of social development.
