Those who might dispute our right to employ the term SURREALISM in the very special sense that we understand it are being extremely dishonest, for there can be no doubt that this word had no currency before we came along. Therefore, I am defining it once and for all: SURREALISM, 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 the thought, in the absence of any control exercised by reason, exempt from any aesthetic or moral concern.
