Laudator Temporis Acti

J.A. Pitt-Rivers (1919-2001), The People of the Sierra (New York: Criterion Books, 1954), pp. 26-27:

Yet how do people behave towards outsiders? The stranger, as in Ancient Greece where he was protected by Zeus, enjoys a special status. It is a duty to assist him, for the reputation of the pueblo is felt to be at stake in his eyes. The visitor of wealth or standing is treated with great courtesy and hospitality. He is probably invited to a glass of wine in the casino, the club. People inquire what brings him and put themselves at his disposal.

This standard of hospitality is a very noble feature of the Spanish people, yet its analysis would not be complete if one were not to point out that it is also a means whereby the community defends itself against outside interference. For a guest is a person who, while he must be entertained and cherished, is dependent upon the goodwill of his hosts. He has no rights and he can make no demands. On the other hand, the good name of the pueblo is his protection. For the sake of that, the members of the community prevent one another from taking advantage of him.
