Out of this cross-fertilization of pseudoscience and spirituality came new sects and eventually one whole new American religion. In the 1830s in Maine, a clockmaker and inventor with the irresistible name Phineas P. Quimby found out about mesmerism. He became a practitioner, hypnotizing sick and unhappy people and persuading them to feel better. Quimby’s work and philosophy were a wellspring of the New Thought movement, a nineteenth-century American precursor to both Scientology and the New Age movement of the twentieth and twenty-first centuries.
