I was wondering this morning as I walked, Does anyone ever prove anything in Philosophy? Oh. I know we prove things all the time in Logic -- All men are mortal, Socrates is a man, Therefore Socrates is mortal. But what about Philosophy per se [as we like to say in the trade]?
Then it occurred to me that every so often a philosopher will disprove something. My favorite examples, not surprisingly, are Hume and Kant who, between them, brought Rational Theology to a screeching halt by decisively refuting every one of the going proofs for the existence of God.
Indeed, I flatter myself that in my small way, I refuted the standard arguments for the moral legitimacy of the majoritarian democratic state. Not quite God, to be sure, but not chopped chicken liver either.
I invite my readers to offer other examples of things philosophers have proved or disproved.
