Socialist Thinkers Beyond the Most Familiar Names

Socialism is often reduced to Marx and Lenin, but its arguments were shaped by people who disagreed sharply with each other: cooperative builders and anarchists, revolutionaries and gradualists, Fabian planners and guild socialists, market socialists and anti-colonial thinkers. This list is for readers who want to understand those internal debates before deciding what they make of them. Entries run roughly in chronological order, and each sets out what the thinker actually argued, who on the left disagreed and why the argument still comes up. Inclusion is an explanation, not an endorsement.
