Repeatability / regularity is a major aspect of something being "real."
I agree, continuity is key.
10.50a: "[Impressions] render the image of a single continuous object (and preserve the continuity at a distance from the original source) according to the proportional impingement [of the impressions] from that source – out of the deep vibration of the atoms in that solid object."
example, what if I were to posit that I have experienced a prolepsis of a being "with a permanent lack of pleasure"
Interesting! Just as we look to the blissful beings as models of the good life, we look to miserable beings to foster our gratitude (DRN book 2 opening, etc). To take this to the (speculative) extreme: Comparing myself to beings that do not die but are miserable -- would, even if I were also miserable, make me grateful at least to be mortal!
