...He also goes on to point out that, within this poetical realm, like that of the subconscious, such haunting and powerful images exist autonomously and for their own sake. 'Do we still have to recall' he asks, 'that the life of creatures populating the surface of canvases and the world of poetry obeys conditions of life different from creatures populating the surface of the earth? That plastic and poetic physiology is not the physiology of living beings? That the plastic or poetic of life of a painting or of a poem obeys other laws than those of the circulation of the blood? That in the plastic or poetic world, a decapitated figure is not a figure without a head?' (Salvador Dalí, quoted in ibid., p. 67).
