Mind-cure

The New Thought movement (also "Higher Thought") is a philosophical movement which developed in the United States in the 19th century, considered by many to have been derived from the unpublished writings of Phineas Quimby. There are numerous smaller groups, most of which are incorporated in the International New Thought Alliance.

New Thought holds that Infinite Intelligence, or God, is everywhere, spirit is the totality of real things, true human selfhood is divine, divine thought is a force for good, sickness originates in the mind, and "right thinking" has a healing effect.

Although New Thought is neither nor doctrinaire, in general, modern-day adherents of New Thought share some core beliefs:

The New Thought movement originated in the early 19th century, and survives to the current day in the form of a loosely allied group of religious denominations, authors, philosophers, and individuals who share a set of beliefs concerning metaphysics, positive thinking, the law of attraction, healing, life force, creative visualization, and personal power.

The teachings of Christian Science are in some ways similar to Quimby's teachings. Its founder, Mary Baker Eddy, was a student and patient of Quimby's but she later disavowed his influence on her Christian Science.
