Incidentally, the theory of personality as per Myers-Briggs, Keirsey, etc., could very well serve as grounds (however ‘theoretical’) for making the case for a return to more classical forms of education. Consider: does an ISFP artist really need to learn about the sciences? does an ENTJ inheriting a ‘family business’ really need to know anything about the Humanities? I say if it’s a life of work that you desire, just go work. Education ought to be for those whose priorities lie within the Life of the Mind.
