World War One was an epoch-making event which transformed the philosophy of Bertrand Russell from based mainly on logic, mathematics and epistemology to haumanitarian issues such as pacificism, freedom and the role of the state. "Collected Papers of Bertrand Russell: Pacifism and Revolution, 1916-18" provides glimpses into this transition and elucidates Russell's main arguments for pacifism and socialism: "No good to the community, of any sort or kind, results from the private ownership of land. If men were reasonable they would decree that it should cease tomorrow..." As private property is protected by the State, and the fraud and plunder that constitute property are sanctioned by legislation and enforced by weapons and war, Russell argued that the State is therefor a great evil and its functions must be taken over by community-based cooperatives and worker's syndicates. Fascinating, provocative and necessary reading.
