If we take in our hand any volume; of divinity or school 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.

David Hume

The sanctity of human life is the most dangerous sophistry ever propagated by philosophy and it is all too well rooted. Because if it means anything it means the in-sanctity of species which are not human.

John Aspinall
