The Three Stigmata of Palmer Eldritch
(1965)
In this wildly disorienting funhouse of a novel, populated by God-like--or perhaps Satanic--takeover artists and corporate psychics, Philip K. Dick explores mysteries that were once the property of St. Paul and Aquinas. His wit, compassion, and knife-edged irony make The Three Stigmata of Palmer Eldritch moving as well as genuinely visionary.
