On The Philosophy of, well, Philosophy

This reminds me of the story of the physicist and the metaphysicist; I don't recall who originated it.A physicist and a metaphysicist each have an idea.The physicist goes to the laboratory and through much labour tests his idea. He finds the idea to be in error, discards it, and carries on.The metaphysicist, however, has no laboratory and no means of testing his idea. He never can tell whether his idea is correct.
