1. I am following the intuition that the continuum hypothesis is true and relates to the universe of discourse in a Neopythagorean system. In brief, the Good cannot be discriminated at all; the nous is too big to be measured even in theory; the world of soul is infinite in size even if it can be measured in theory (e.g. it is measurable, but only by the nous); and the world of matter is puny and boring.
2. I have already discussed the computability of the various levels of reality.
3. The term "imagination" is due to St. Synesius. Plutarch calls it "the mind" (which I really like but don't use because the Neoplatonists give that name to the nous), while Plotinus calls it "the lower soul." Prophyry and Proclus are more persnickety and call the soul-body, the "luminous vehicle;" the imagination-body, "the pneumatic vehicle;" and the physical-body, "the shell-like vehicle."
4. The Intellect exists outside of time and can comprehend all things simultaneously. The soul exists outside of time but can only comprehend things one-at-a-time (and this sequential comprehension is what gives rise to time). The imagination exists within time but, if it is idealized, can live forever. The body is, of course, mortal. The body and imagination come into being more-or-less together, but the imagination-body dies slower than the physical body does (owing to its lesser neediness).
5. The natural bodies always require external sustenance; the imagination-body ideally always has enough, while the physical-body never does.
6. The nous is the definition of all truth. Souls have a perfect understanding of truth from a given perspective. The imagination-body ideally has an intuition of truth (that is, it knows the right answers but does not know why), while the physical-body has only guesswork.
