He is viewing the discontuity between pure mathematics as a perfect system and the messy scientific results of observation Trixie.
Go out on a 15 mile hike, and look at a steep hill… estimate quickly the height in your head. Then look at it again carefully… the more tired you get, the more likely you are to overestimate the inclination of the hill by 15°. It has been theorized this is a adaptation to make us lazier, so we don’t waste endless energy brazengly going up hill.
Or… hold in your urine, then go out for a five mile run, and come back… you will find your pissing yourself slightly as you approach your house and toilet thinking relief is coming, it can’t wait… yet you were able to hold it prior… purely psychosomatic.
Likewise getting too tired to carry on when near the finish, premature ejaculation in mere proximity. Zeno’s space paradoxes… humans do all sorts of oddities in regards to mathematics, doesn’t add up to our presumptions often.
Our presumptions are as much something we rationally create as nature provides for. We can’t escape from this, but can become aware of it. Cicero tackled the irregularities of abstract, imaginary space in his mnemonics… we imagine say… a space from our memory, either real or made up… and walk through it. What we think we see is informed by expectations, a non-visual memory… what we actually see often doesn’t match up. Solipism has many irregularities to it, as would a simulated universe. Matrix got around this by not denying it, but offering a way out. Gnostics usually (99% of the time, minus some forum Gnostic here who insisted otherwise due to the peculiar twist his sect had to offer) reject this world. They seek a better world completely out of space and time.
Given this topic and my mention of Augustine, it should be noted he was often bombarded by rather ignorant pagans asking why God choose, if he was eternal… to build the universe Ex Nihilo in this particular space, and not somewhere else, or why this particular time, and not another point.
Pagans then and science now, like many Christians, are quite aware space and time started from the same point, and always was linked by some sort of relativism (though not necessarily Einstein’s take). He had to deal with idiot skeptics who thought the universe existed independent of space and time! We still deal with these mouth breathers to this day, I had to remind some Nietzschean on this forum a while back that Christians didn’t think in the mindset they were abscribing us as thinking in, with God “In” the universe… why can’t we find or prove him. That was never a possibility within Christian theology, by our original default. Our sciences are material, looking at physics. You can’t prove God existed anymore than you can prove what existed before the big bang or beyond the innards of a black hole.
Mental constructs of pure mathematics don’t always match up.
These are some of the oldest debates in philosophy. You find them hidden in countless threads across this forum piecemeal… few philosophies exist in the west that doesn’t touch upon them in some way.
(I never prematurely ejaculated. Wish I could though, would save me time).
