Reason, Nothingness, Motion

Leibniz conceives Experience to be a Continuum, in which Minute Perceptions function as transitional elements.  Plainly, the concept entails an infinite regress, since any two such moments requires a third to mediate them.  So, at the limit of the regress is instantaneous differentiation, just as it is for Newton, in his effort to quantify motion.  Thus, the absolutely small, i. e. the correlate of the absolutely large that constitutes Kant's Sublime, is, perhaps, not, as has been previously suggested, Nothingness, but pure Motion.  But, these are not necessarily alternatives--from a Parmenidean perspective, Motion is Nothingness, to each of which Kantian Reason is inadequate.
