Margins organizes itself in large part around the idea of the metaphorical consistency of metaphysical thinking as a repetition of physics; metaphysics metaphorically uses physis to give itself consistency, or a consistently present body. While metaphysics might understand itself as based in and dealing with concepts or to be occurring only at the level of ideas, in actuality, it is constantly deploying physical metaphors to guarantee the continuity of its presence. Presence would be a metaphorically continuous body which would constitute the consistency of truth conceived of as metaphysically certain. At the same moment metaphysics presents itself as being nothing but an ideal and conceptual proposition. Metaphysics appears to be practiced purely at the level of concepts and ideas, however in using metaphors in the constitution of its sense, it actually and covertly relies on a fabricated, metaphorically physical continuity or presence. This presence underwrites the continuity of the truth of its ideas. Because of this Derrida argues philosophy has always based itself in an exclusion of the metaphorical, as a way of thinking not compatible with concepts. Metaphors are the other of concepts, metaphysical thinking, and metaphysical ideality cannot be seen to be implicated with them. In Derrida's reading however, it constantly is, as it is the concept's location in metaphysical space, which allows one concept to be intelligible from another. That is, in the last instance it isn't the internal coherence of the idea or concept which distinguishes it from other concepts or ideas but rather just the metaphoric, corporal continuity which it is secretly presumed to possess. In this sense, metaphysics is “white mythology”, the mythology practiced by the white man, as that culture which understood as eminently 'rational' and defined by the absence of mythology in its thought. All of Derrida's thought takes place in a kind of 'reprojected space', or he derives the sense of his ideas in terms of a conceptual space where the events which define the the pre-understood coherence of metaphysics would be taking place. This space is like the unconscious of metaphysics, but thinking this space and its objects as a type of insubstantial model is the basis for the practice of deconstruction. So while there is the conceptual level of metaphysics in which for instance nature and culture, or even concept and metaphor itself, conducts themselves as a series of opposed tropes or concepts, there is a 'hidden', sublimated conceptual background which metaphysics both disavows but uses. For Derrida then thinking the problem of metaphysics involves thinking this relationship between a consciously represented conceptual level and a disavowed, unconscious, substantial metaphor.
