Tuomas Tahko (left) and Thomas Hofweber (right) on the foundations of metaphysics.
If metaphysics is a form of genuine inquiry, then presumably metaphysicians investigate questions of fact. But it seems that for any given type of fact, there is already a discipline that investigates facts of that type. For instance, physicists investigate physical facts; mathematicians investigate mathematical facts—and so on. Perhaps there is a special realm of facts investigated only by metaphysicians, but it is unclear what such facts would be like. Alternatively, perhaps metaphysics plays the role of verifying results obtained in other disciplines, but it is unclear that metaphysicians are qualified to check the work of physicists and mathematicians. So what exactly is it that metaphysicians do? In this episode, Tahko and Hofweber grapple with this question.
