It is not how much one makes but to what purpose one spends.

The names of great painters are like passing-bells: in the name of Velasquez you hear sounded the fall of Spain; .in the name of Titian, that of Venice; in the name of Leonardo, that of Milan; in the name of Raphael, that of Rome. And there is profound justice in this, for in proportion to the nobleness of the power is the guilt of its use for purposes vain or vile; and hitherto the greater the art, the more surely has it been used, and used solely, for the decoration of pride or the provoking of sensuality.
