He wrote many books, pamphlets and articles, the most prominent being The Conquest of Bread and Fields, Factories and Workshops, and his principal scientific offering, Mutual Aid: A Factor of Evolution. He also contributed the article on anarchism to the Encyclopædia Britannica Eleventh Edition, and left unfinished a work on anarchist ethical philosophy.
