We live in a metaphysical age. And I do not mean just that too many people still believe The Prophecies of Nostradamus and/or the horoscopes found in most local newspapers. It is a metaphysical age among philosophers – even among those who shun horoscopes and are frankly embarrassed to fi nd Nostradamus so prominently displayed in the metaphysics section of their campus bookstore. Nowadays, distinguished philosophers in prestigious departments proudly call themselves metaphysicians. They all know, of course, that Carnap and his Viennese friends campaigned in the late twenties and early thirties against metaphysics.
