Phaemon the philosopher had a little dog whom he had trained to go to the butcher every bring back a lump of meat in a basket. This virtuous creature, who would never dare to touch a scrap until Phaemon gave it permission, was one day set upon by a pack of mongrels who snatched the basket from its mouth and began to tear the meat to pieces and bolt it greedily down. Phaemon, watching from an upper window, saw the dog deliberate for a moment just what to do. It was clearly no use trying to rescue the meat from the other dogs: they wouild kill it for its pains. So it rushed in among them and itself ate as much of the meat as it could get hold of. In fact it ate more than any of the other dogs, because it was both braver and cleverer.
– from Claudius the God, by Robert Graves, 1935
Such is the cruel fate of the virtuous when faced with suffuse and irradicable corruption.
