The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.

So far no chemist has ever discovered exchange-value either in a pearl or a diamond.

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 directing motive, the end and aim of capitalist production, is to extract the greatest possible amount of surplus value, and consequently to exploit labor-power to the greatest possible extent.

The more the division of labor and the application of machinery extend, the more does competition extend among the workers, the more do their wages shrink together.

The will of the capitalist is certainly to take as much as possible. What we have to do is not to talk about his will, but to enquire about his power, the limits of that power, and the character of those limits.
