Just as the savage must wrestle with nature to satisfy his wants, to maintain and reproduce life, so must civilised man, and he must do so in all social formations and under all possible modes of production.

Nature is man's inorganic body - that is to say, nature insofar as it is not the human body. Man lives from nature - i.e., nature is his body - and he must maintain a continuing dialogue with it is he is not to die. To say that man's physical and mental life is linked to nature simply means that nature is linked to itself, for man is a part of nature.

Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life.

A circuit performed by a capital and meant to be a periodical process, not an individual act, is called its turnover. The duration of this turnover is determined by the sum of its time of production and its time of circulation.

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.

The burgeoisie, by the rapid improvement of all instruments of production, by the immensely facilitated means of communication, draws all nations into civilization.
