The notion that a man requires no special schooling in philosophy is a nonsensical and superficial one. For philosophy tries to do in complete consciousness and in complete thoroughness what the unphilosophical are always doing in an unsystematic casual and unconscious way. It seeks to impart a proper understanding of the meaning of the world so that those who have to live in this world may live aright, successfully, and more happily.
