Every 'I' is the imperfectly realised centre of its world, a world which includes every other 'I', which are 'objects' such as can only be understood as equally the centre of each its own world. A world, then, contains the 'addresses' of an unlimited plurality of other worlds. Large parts of these worlds are treated as if they are of overlapping reference, given a transformation in perceptual and conceptual perspective. You think of the totality of this as some sort of kaleidoscopic or fractal reality, but again that totality is a projection from within your world towards a more complete world of consensus than the one you normally take as reference. There is nothing to be explained here, the point is rather to refrain from explaining so that the strangeness of this meta-phenomenon can be appreciated. There is indeed, nothing like it, it is neither object-like nor subject-like. One 'I' can move into the most intimate 'proximity' of another 'I' without in the least disrupting the general features of the pattern, since the pattern itself is made out of the open-ended side-effects of such interactions.
