That is interesting, although I'd say that Kant didn't develop this idea from a specific philosophical position rather than as a, shall we say, "intra-scientific" hypothesis (AFAIK, Kant was quite literate scientifically and was well versed in Newton's mechanics. My father likes to tell the story that of all the lectures he had to give at the University of Königsberg,
Physical Geography was his favourite - for him, who never left Königsberg in his entire life
).
Maybe it's time for some hinting (no bludgeoning this time, please, George
)
The finding involves the numbers 5, 6 and 7.
The man who had the idea can be considered a famous astronomer.
