"He has no personal interests, no business affairs, no emotions, no attachments, no property, and no name. His entire being is devoured by one purpose, one thought, one passion - the revolution. Heart and soul, not merely by word but by deed, he has severed every link with the social order and with the entire civilized world; with the laws, good manners, conventions, and morality of that world. He is its merciless enemy and continues to inhabit it with only one purpose - to destroy it."
Sergey Nechayev, The Revolutionary Catechism, 1869.
