Simulations of God is a brilliant, provocative work by one of the great creative scientists of the twentieth century, John Lilly, M.D.. In it he examines the sacred realms of self, religion, science, philosophy, sex, drugs, politics, money, crime, war, family, and spiritual paths "with no holds barred, with courage and a sense of excitement". Lilly's purpose is to provide readers with a unique view of inner reality to help them unfold new areas for growth and self-realization.
