It seems to me that Tirebiter's question is making these issues look more and more like religious dogma. I'm beginning to think of them as 'Diesel Metaphysics'.
To bastardize David Hume:
"When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or diesel metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: for it can contain nothing but sophistry and illusion"
