Psychology once again states: people who are self-confident, read, are not sex-crazed, and don’t believe in collectivist policies have SOME sort of mental illness.
Allow me to skewer this soft science with something learned in high-level math classes: all measurement is done from a base: be it a point, line, or plane.
Why should psychologists, who are all pretty screwed up, use themselves as the reference point?
Because we all do. It is inescapable. We are only aware of the world through ourselves so that has to be our base. For high order mathematics the mathematician is assuming the role of such and, according to his particular value system, again one that is internalized, he is playing an intellectual game, solving an intellectual puzzle, and in that he is objective. Yet, he is being subjectively objective in that it, objectivity, conforms to his subjective values.
In other parts of his life he is probably not so objective.
High level math? I learned that doing carpentry.
