The capitalist mode of production and accumulation, and therefore capitalist private property, have for their fundamental condition the annihilation of self - earned private property: in other words, the expropriation of the labourer.

When the labourer co-operates systematically with others, he strips off the fetters of his individuality, and develops the capabilities of his species.

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

In proportion as capital accumulates, the lot of the laborer, be his payment high or low, must grow worse.

As a beast of toil an ox is fixed capital. If he is eaten, he no longer functions as an instrument of labour, nor as fixed capital either.

An increase in the productivity of labour means nothing more than that the same capital creates the same value with less labour, or that less labour creates the same product with more capital.
