Amadeo Bordiga quotes:

In the name of a greater civilization, we curse those who for the sake of their ambitious dreams, brought about the massacre of so many young lives. No matter how brutal the crime, you will always get glorification of its heroism and tradition from the eunuchs of bourgeois culture.

There cannot exist in the future an economy which is still mercantile but which isn't capitalist anymore. Before capitalism there were economies which were partially mercantile, but capitalism is the last of this genre.

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.

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

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.
