I did not know that the Quadrivium is sub-divided into two groups for quantity and size. I had never made that connection before. At first glance, with the modern callouses over the eye of my soul, it seemed to me, prior to this lesson, that these sciences were all exclusive from one another. As I think about it now, I think this is a result of looking at these only through the temporal things which subsist in these sciences, just as the interlocutor does from the Republic. If we were to assume materiality as our first principle, then what does transactional flow, configurative partitioning, beautiful entertainment, and shipping cadences have in common essential? Nothing, I would say at first, because all of these bodily things are very different from one another; therefore, these must not be related essentially, but superficially. On the contrary, this must be a flawed misconception, and just coming to know that they are related immaterially by means of quantity and size is mind-blowing to be frank.
