"We know today that this kingdom of reason was nothing more than the idealized kingdom of the bourgeoisie; that this eternal Right found its realization in bourgeois justice; that this equality reduced itself to bourgeois equality before the law; that bourgeois property was proclaimed as one of the essential rights of man; and that the government of reason, the Contract Social of Rousseau, came into being, and only could come into being, as a democratic bourgeois republic. The great thinkers of the 18th century could, no more than their predecessors, go beyond the limits imposed upon them by their epoch.

But, side by side with the antagonisms of the feudal nobility and the burghers, who claimed to represent all the rest of society, was the general antagonism of exploiters and exploited, of rich idlers and poor workers."

- Friedrich Engels, 1848
