If consciousness were made up out of discrete moments with nothing, that is no sort of consciousness whatsoever, 'between' them, then you wouldn't know it was like this since you could not have access to any awareness of the separations between moments - analogous perhaps to the nothing space of a general anaesthetic. In this case nothing could depend on the relations, continuities or discontinuities of such moments since there would be no common scale or manifold that connected the 'output' of one moment to the 'input' of the next. They could be neither similar or different. This idea however represents a deep model of consciousness, and a conscious moment must always contain a model of consciousness. This internal model is only a model of the positive polarity of experience and hence can very well be one of discrete moments. The negative polarity which could be called the transcendental subject is not part of the model, and is identically the same in all conscious moments and models of conscious moments.
