Under private property, each tries to establish over the other an alien power, so as thereby to find satisfaction of his own selfish need. The increase in the quantity of objects is therefore accompanied by an extension of the realm of the alien powers to which man is subjected, and every new product represents a new potentiality of mutual swindling and mutual plundering.

History repeats itself, the first as tragedy, then as farce.

The ruling ideas of each age have ever been the ideas of its ruling class.
