The split between the two trends of Bolshevism issued from questions of a very practical nature. [Alexander] Bogdanov and his group condemned participation in parliamentary, "bourgeois" politics. [Vladimir] Lenin, on the other hand, set the struggle for political power as the main task of the party. He was not occupied with creating and implanting an idea of the future of socialism; he thought of this more as a development to be expected from the period following the revolution. Instead he was preparing the organizational and political-intellectual grounds for a revolution that would be capable of overthrowing tsarism.
