Corporeality of G-d
It is interesting to me because I believe that the school of belief that G-d is incorporeal seems to have arrived at this assumption through reasoning and logic, though in many ways the more literal reading of the Tanach would certainly leave the door open for a corporeal Deity. In other words, G-d seems to walk through the garden of Eden, G-d speaks from a cloud, G-d descends down to Mt Sinai, etc... Yet, the rationalist side argued that by definition, G-d cannot be corporeal. But this really seems to be applying our own ideas about what G-d can and cannot be to the text. In many ways this leads to the crux of the matter, which is: is the human mind capable of discerning whether a particular system of logic is 'bulletproof' and therefore leads to an indisputably 'true' conclusion?
Those of us in computer science and mathematics related fields know how far away we are from being able to conclusively logically prove anything non-trivial. As the famous computer scientist Donald Knuth wrote in a memo, "Beware of bugs in the above code. I've only proven it correct, not tested it!"
