Q. About Rationality and Nature

[Whateverist]

It isn't the existence of whatever it is that gives rise to our sense data which depends on pure reason, just us.

Go on... I think I agree but can you spell it out a little more?

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.

That is interesting but I'm afraid I don't know what else is to be said about the other matter. I take it on faith that our sense data and cognition have arisen biologically to successfully cope with something real of which we are apart. Anything paradoxical concerning reality is just our cognition revealing again that it hasn't evolved to ponder the depths of our navels or answer riddles.
