In proportion as the bourgeoisie, i.e., capital, is developed, in the same proportion is the proletariat, the modern working class, developed - a class of labourers, who live only so long as they find work, and who find work only so long as their labour increases capital. These labourers, who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.
Karl MarxThe democratic concept of man is false, because it is Christian. The democratic concept holds that . . . each man is a sovereign being. This is the illusion, dream, and postulate of Christianity.
Karl MarxAll science would be superfluous if the outward appearance and the essence of things directly coincided.
