The Conquest of Bread by Peter Kropotkin

Expropriation, such then is the problem which History has put before the men of the twentieth century: the return to Communism in all that ministers to the well-being of man.

But this problem cannot be solved by means of legislation. No one imagines that. The poor, as well as the rich, understand that neither the existing Governments, nor any which might arise out of possible political changes, would be capable of finding such a solution. They feel the necessity of a social revolution; and both rich and poor recognize that this revolution is imminent, that it may break out in a few years.
