"Well, Mitchell, I don't know at all your approach to medicine. Perhaps you regard it as an opportunity to become one of those bedside manners with a list of proper pills to give the patient - particularly when you don't know what is the matter with him. Or perhaps your aim is to become an eminent carpenter with a knife and a chisel and a saw. Perhaps even you'll flow over with the nobility of relieving humanity's suffering. I'll tell you my approach to medicine! It is a game in which man pits his brains against the forces of destruction and disease. In the beginning I don't expect you to participate in the game. You'll only listen and accept. You will study and you will make notes and you will memorize... and you will do all this only because I tell you to."
