The teacher's standpoint is not arbitrary. It is neither simply dependent on what students think they want or happen to be in this place or time, nor is it imposed on him by the demands of a particular society or the vagaries of the market. Although much effort has been expended in trying to prove that the teacher is always the agent of such forces, in fact he is, willy-nilly, guided by the awareness, or the divination, that there is a human nature, and that assisting its fulfillment is his task. He does not come to this by way of abstractions or complicated reasoning. He sees it in the eyes of his students. Those students are only potential, but potential points beyond itself; and this is the source of the hope, almost always disappointed but ever renascent, that man is not just a creature of accident, chained to and formed by the particular cave in which he is born.
--Allan Bloom, The Closing of the American Mind
