Under his [ Marc Chagall ] sole impulse metaphor made its triumphal entry into modern painting. - André Breton

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.

Apollinaire asserted that Chirico's first paintings were done under the influence of kinesthetic disorders (migraines, colic, etc.)

Why should I not expect from the sign of the dream more than I expect from a degree of consciousness which is daily more acute? Can’t the dream also be used in solving the fundamental questions of life? Are these questions the same in one case as in the other and, in the dream, do these questions already exist? Is the dream any less restrictive or punitive than the rest? I am growing old and, more than that reality to which I believe I subject myself, it is perhaps the dream, the difference with which I treat the dream, which makes me grow old.
