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.

Superstition, in all times and among all nations, is the fear of a spirit whose passions are those of a man, whose acts are the acts of a man; who is present in some places, not in others; who makes no places holy and not others; who is kind to one person, unkind to another; who is pleased or angry according to the degree of attention you pay him, or praise you refuse to him; who is hostile generally to human pleasure, but may be bribed by sacrifice of a part of that pleasure into permitting the rest. This, whatever form of faith it colors, is the essence of superstition.
