Imagine models floating above each other as in distinct dimensions: it is not their homologies that prove suggestive or fruitful, but rather the infinitesimal divergences, the imperceptible lack of fit between the levels – extrapolated out into a continuum whose stages range from the pre-choate and the quizzical gap, to the nagging tension and the sharpness of contradiction itself – genuine thinking always taking place within empty places, these voids that suddenly appear between the most powerful conceptual schemes. Thinking is thus not the concept, but the breakdown in the relationships between the individual concepts, isolated in their splendour like so many galactic systems, drifting apart in the empty mind of the world.
