Zeno used to tell a story about Crates, to this effect: One day
Crates was sitting in a shoemaker's shop, reading aloud Aristotle's
_Exhortation_ (to Philosophy), addressed to Themison, king of the
Cyprians, in which the king is reminded that he possesses, in an
          degree, all the conditions of philosophy, superabundant
wealth, and high position.
