As a result of civilization, the perceived world is a narrow structure dominated by those in an authoratative position, as in Plato's "In the land of the blind, the one eye'd man is King," This narrow structure falls far short of human experience in that it categorizes every thing into separate parts- Therefore a schizm is presented manifesting in a split in behavior as well as in conscious awarness of one's behavior. As a result it is to be expecte dthat one would feel divided from one self and the "other" that which is outsid eone self.
If a person is able to intergrate this schism meaning to become schizoid- they can be considered normal. If one is not able to intergrate this schizm because they are too strong and genuine then society will see them as Schizophrenic because they can not intergrate or digest the lie.
As Nietzsche informs everything human involves a great falsification, a great reduction into appearances that represent nothing real- Similiar to Plato's cave metaphor in the "Republic, Book VII.
Liers are healthy in this society- people who are genuine are deemed unhealty and labled with mental hale diagnoses. Th eindividual must take on the onus to save society an dits economics. If one is genuinely interested in healing it must start with the individual and society is the problem.
