Surrealism is a cultural movement that began in the early 1920s, and is best known for its visual artworks and writings. The aim was to "resolve the previously contradictory conditions of dream and reality." Artists painted unnerving, illogical scenes with photographic precision, created strange creatures from everyday objects and developed painting techniques that allowed the unconscious to express itself and/or an idea/concept. Surrealist works feature the element of surprise, unexpected juxtapositions and non sequitur; however, many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost, with the works being an artifact. Leader André Breton was explicit in his assertion that Surrealism was, above all, a revolutionary movement. Surrealism developed out of the Dada activities during World War I and the most important center of the movement was Paris. From the 1920s onward, the movement spread around the globe, eventually affecting the visual arts, literature, film, and music of many countries and languages, as well as political thought and practice, philosophy, and social theory. Surrealist Manifesto Breton wrote the manifesto of 1924 that defines the purposes of the group. He included citations of the influences on Surrealism, examples of Surrealist works and discussion of Surrealist automatism. He defined Surrealism as: Dictionary: Surrealism, n. 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. Encyclopedia: Surrealism. Philosophy. Surrealism is based on the belief in the superior reality of certain forms of previously neglected associations, in the omnipotence of dream, in the disinterested play of thought. It tends to ruin once and for all other psychic mechanisms and to substitute itself for them in solving all the principal problems of life.
