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.
Friedrich EngelsThe slave frees himself when, of all the relations of private property, he abolishes only the relation of slavery and thereby becomes a proletarian; the proletarian can free himself only by abolishing private property in general.
Friedrich EngelsThe first class opposition that appears in history coincides with the development of the antagonism between man and woman in monogamous marriage, and the first class oppression coincides with that of the female sex by the male.
Friedrich EngelsFreedom 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 EngelsThe proletarians, driven to despair, will seize the torch which Stephens has preached to them; the vengeance of the people will come down with a wrath of which the rage of 1795 gives no true idea. The war of the poor against the rich will be the bloodiest ever waged.
Friedrich Engels...it was always our view that in order to attain this [proletarian revolution] and the other far more important aims of the future social revolution, the working class must first take possession of the organised political power of the state and by its aid crush the resistance of the capitalist class and organise society anew.
Friedrich Engels
