In taking the measure of a man’s cultural refinement, we must examine the degree to which he is practiced in the art of hospitality. And when I say art, I mean this in a literal sense. Arts are not inborn; they must be studied and honed with constant use. A culture that teaches its members how to treat guests is a confident one; it is a culture that has, to some degree at least, liberated itself from the oppressions of acquisitiveness and greed, and has embraced some aspects of the communitarian ethic. It is also a culture that understands the value of reciprocity: the idea that a good turn done for one today, may mean a good turn done for oneself tomorrow.
