Breton's Surrealists wanted to place themselves outside. What is it what they want to put outside? Pure thought. That is, the only metaphysical world, reflection. But from a materialistic standpoint thought is a reflection of matter — as in a mirror. The metaphysical world is not able to surmount the material world which produces it. One has to think of SOMETHING. But for thought to be dialectical, it's object / it's "thing" must cease to be attached to everyday life.
