5 The fact is that my native land is a prey to barbarism, that in it men's only God is their belly, that they live only for the present, and that the richer a man is the holier he is held to be. Moreover, to use a well-worn proverb, the dish has a cover worthy of it; for Lupicinus is their priest. Like lips like lettuce, as the saying goes— the only one, as Lucilius tells us, at which Crassus ever laughed— the reference being to a donkey eating thistles. What I mean is that an unstable pilot steers a leaking ship, and that the blind is leading the blind straight to the pit. The ruler is like the ruled.
