Q. About Rationality and Nature

[Thumpalumpacus]

Also, as a side, it is kind of remarkable to read what Kant argues as his conception of God on the basis of pure logic and what modern cosmology has dubbed the Singularity.

Not to derail your thread, but Kant is also the guy who came up with what is basically our current theory of stellar formation from nebulae. He also, having read the hypothesis that the Milky Way was a spinning agglomeration of stars, first conceived of the idea of multiple galaxies in our Universe, which he referred to with the (to me) haunting phrase "island universes".

Here's a blogpost about his astronomical contributions: http://www.fromquarkstoquasars.com/kant/
