"Human beings have been trying to change each others' minds since they first discovered they had them. Brainwashing is more ambitious, and more coercive, than simple persuasion, and unlike older cognates such as indoctrination, it has become closely associated with modern, mechanistic technology. It is a systematic processing of non-compliant human beings which, if successful, refashions their very identities."
