Ego is a structure that is erected by a neurotic individual who is a member of a neurotic culture against the facts of the matter. And culture, which we put on like an overcoat, is the collectivized consensus about what sort of neurotic behaviors are acceptable.
Culture is a perversion. It fetishizes objects, creates consumer mania, it preaches endless forms of false happiness, endless forms of false understanding in the form of squirrelly religions and silly cults. It invites people to diminish themselves and dehumanize themselves by behaving like machines.
