The place of the worst barbarism is that modern forest that makes use of us, this forest of chimneys and bayonets, machines and weapons, of strange inanimate beasts that feed on human flesh.

The degeneration of the revolution in Russia does not pass from the revolution for communism to the revolution for a developed kind of capitalism, but to a pure capitalist revo­lution. It runs in parallel with world-wide capitalist domination which, by successive steps, eliminates old feudal and Asiatic forms in various zones. While the historical situation in the seventeenth, eighteenth and nineteenth centuries caused the capitalist revolution to take liberal forms, in the twentieth century it must have totalitarian and bureaucratic ones.

The whole discussion now underway on revolutionary forms in Russia and in China boils down to the judgement to be made of the historical phenomenon of the appearance of industrialism and mechanisation in huge areas of the world previously dominated by landed and precapitalist forms of production.Constructing industrialism and mechanising things is supposedly the same as building socialism whenever central and national plans are made. This is the mistaken thesis.

To exploit living labour, capital must destroy dead labour which is still useful. Loving to suck warm young blood, it kills corpses.
