"Bolshevism combines the characteristics of the French Revolution with those of the rise of Islam .... Marx has taught that Communism is fatally predestined to come about; this produces a state of mind not unlike that of the early successors of Mahommet .... Among religions, Bolshevism is to be reckoned with Mohammedanism rather than with Christianity and Buddhism. Christianity and Buddhism are primarily personal religions, with mystical doctrines and a love of contemplation. Mohammedanism and Bolshevism are practical, social, unspiritual, concerned to win the empire of this world". (Bertrand Russell, The Practice and Theory of Bolshevism: London: George Allen and Unwin, 1920 pp. 5, 29, 114).
