Oscar Wilde deemed his life "perfect," and described him as a man with "a soul of that beautiful white Christ which seems coming out of Russia." He is PETER ALEXEYEVICH KROPOTKIN (1842-1921), communist advocate and "anarchist prince." Mutual Aid: A Factor of Evolution, first published in 1902, is his best known book. Written as a series of essays for a British literary journal, this intriguing work filters concepts of evolution through Kropotkin's appreciation for altruism and anarchy, positing cooperation not merely as a beneficial political concept but as an approach that has been-and will continue to be-vital to the long-term survival of humanity. Kropotkin explores "mutual aid" among "animals," "savages," "barbarians," and in the medieval and modern world, and also discusses nesting associations, checks to overmultiplication, adaptations to avoid competition, the origin of the family, the origin of the guilds, and other related issues. Anyone interested in the science of evolution and its influence on the shape of human societies will find this a fascinated read.
