[4] : THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993)

sorcery, n.  the ancient prototype and forerunner of political
influence.  it was, however, deemed less respectable and sometimes was
punished by torture and death.  augustine nicholas relates that a poor
peasant who had been accused of sorcery was put to the torture to
compel a confession.  after enduring a few gentle agonies the
suffering simpleton admitted his guilt, but naively asked his
tormentors if it were not possible to be a sorcerer without knowing
it.
