Surrealism is a pure psychic automatism, by which one proposes to express, either verbally, in writing, or by any other manner, the real functioning of thought. Dictation of thought in the absence of all control exercised by reason, outside of all aesthetic and moral preoccupation.

André Breton is known best as the founder of Surrealism. His writings include the first Surrealist Manifesto (Manifeste du surréalisme) of 1924, in which he defined surrealism as “pure psychic automatism”.
