15.5: Casanova

On 25 July 1755, Giacomo Casanova—arguably the most famous libertine in Western history—was arrested for possession of illicit literature. Among the books authorities confiscated from his house were the Key of Solomon, the Zohar, and the devil-conjuring Picatrix. Early in his life, Casanova had attempted to enter the priesthood and he knew enough of Kabbalah to convince a senator and three of his occult-inclined friends that he possessed a secret numerological formula. And yet, in his autobiography, Casanova professed disdain for magical thinkers of all kinds, iterating at every opportunity the Enlightenment credo that one must only trust reason in answering life's many questions and quandaries. How can a man be both a magician and a disbeliever in magic?
