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.
