“We do not and cannot know which spark — of the innumerable sparks that are flying about in all countries as a result of the world economic and political crisis — will kindle the conflagration, in the sense of raising up the masses, we must, therefore, with our new and communist principles, set to work to stir up all and sundry, even the oldest, mustiest and seemingly hopeless spheres, for otherwise we shall not be able to cope with our tasks, shall not be comprehensively prepared, shall not be in possession of all of the weapons and shall not prepare ourselves either to gain victory over the bourgeoisie (which arranged all aspects of social life — and has now disarranged them — in its bourgeois fashion), or to bring about the impending communist reorganisation of every sphere of life, following that victory.”
— Vladimir Lenin, “‘Left-Wing’ Communism: An Infantile Disorder”
