The New Thought movement (also Higher Thought) is a new religious movement that coalesced in the United States in the early 19th century. New Thought was seen by its adherents as succeeding "ancient thought", accumulated wisdom and philosophy from a variety of origins, such as Ancient Greek, Roman, Egyptian, Chinese, Taoist, Hindu, and Buddhist cultures and their related belief systems, primarily regarding the interaction among thought, belief, consciousness in the human mind, and the effects of these within and beyond the human mind. Though no direct line of transmission is traceable, many adherents to New Thought in the 19th and 20th centuries claimed to be direct descendants of those systems.
Although there have been many leaders and various offshoots of the New Thought philosophy, the origins of New Thought have often been traced back to Phineas Quimby, or even as far back as Franz Mesmer, who was one of the first European thinkers to link one's mental state to physical condition. Many of these groups are incorporated into the International New Thought Alliance. The contemporary New Thought movement is 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.
