First published in 1924, Peter Kropotkin’s “Ethics: Origin and Development” is a classic of philosophy and ethics that constitutes one of the fundamental texts of late 19th and early 20th century anarchism. Within it, Kropotkin traces the development of moral teachings from ancient Greece and the Middle Ages to the 19th century philosophers, continuing the argument that sociable morality is essential to human survival. Pyotr Alexeyevich Kropotkin (1842–1921) was a Russian writer, activist, revolutionary, economist, scientist, sociologist, essayist, historian, researcher, political scientist, geographer, geographer, biologist, philosopher and advocate of anarcho-communism. He was a prolific writer, producing a large number of pamphlets and articles, the most notable being “The Conquest of Bread and Fields, Factories and Workshops” and “Mutual Aid: A Factor of Evolution”. This classic work is being republished now in a new edition complete with an excerpt from “Comrade Kropotkin” by Victor Robinson.
