Paris, 1924: André Breton published "Le Premier Manifeste du Surréalisme" (The First Manifesto of Surrealism). He gave his definition of the term "Surrealism":

Surrealism, n. Psychic automatism in its pure state by which one proposes to express - verbally, by means of the written word, or in any other manner - the actual functioning of thought. Dictated by thought, in the absence of any control exercised by reason, exempt from any aesthetic or moral concern.

Encyclopedia. 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.

My favourite sentence from the Manifesto: "The wood is of glass."
