In order to arouse sympathy, the aristocracy was obliged to lose sight, apparently, of its own interests, and to formulate its indictment against the bourgeoisie in the interest of the exploited working class alone. Thus, the aristocracy took their revenge by singing lampoons on their new masters and whispering in his ears sinister prophesies of coming catastrophe.

What the bourgeoisie therefore produces, above all, are its own grave-diggers. Its fall and the victory of the proletariat are equally inevitable.

Capitalist production, therefore, develops technology, and the combining together of various processes into a social whole, only by sapping the original sources of all wealth - the soil and the labourer.

One of the most difficult tasks confronting philosophers is to descend from the world of thought to the actual world.

Philosophy stands in the same relation to the study of the actual world as masturbation to sexual love.

There is no greater stupidity than for people...to marry and so surrender themselves to the small miseries of domestic and private life.

Be aware that the reward for labour, and quantity of labour, are quite disparate things.
