We all create an outward self with which to face the world, and some people come to believe that is what they truly are. So they people the world with doctors who are nothing outside of the consulting-room, and judges who are nothing when they are not in court, and business men who wither with boredom when they have to retire from business, and teachers who are forever teaching. That is why they are such poor specimens when they are caught without their masks on. They have lived chiefly through the Persona.
