In Episode 41 of Hidden Forces, Demetri Kofinas speaks with Jim Holt about the philosophy of science, ethics, and metaphysics.

Jim Holt is on a quest to understand the fundamental nature and meaning of our universe. What is infinity? Is time real? Why does the world exist? These are the most important questions that humanity has ever pondered. When attempting to answer such large, existential questions, it’s not enough to use observational evidence alone. This is where metaphysics comes in.

Unlike the hard-nosed, falsifiable propositions that form the foundation of empirical science, metaphysics poses questions for which definitive answers are hard to come by. Aristotle famously heralded the field as “the first philosophy,” since it explores those questions which are generally accepted as being the most basic and vital.

In short, this branch of philosophy seeks to explain the nature of being, reality, and the meaning of existence. Since metaphysics is not based on falsifiable propositions, it is is not bounded by the constraints of formal logic or scientific truth. As a result, finding conclusive answers to the perennial questions that it poses may well be impossible.

Still, something about these questions jabs at us. Why? Perhaps it is in our nature to question everything, even those things for which answers do not exist. Or perhaps the act of engaging in ontological arguments is itself the goal. In either case, in our answer-based culture, exploring the philosophy of science and metaphysics is a necessarily humbling experience. It forces us to contend with the mystery of our own existence, and it presses the limits of our explanatory powers.

In his latest book, “When Einstein Walked with Gödel: Excursions to the Edge of Thought,” Jim Holt explores the nature of logic and truth. And in this episode, he joins host Demetri Kofinas for an hour-long conversation on the philosophy of science and metaphysics. Over the course of the discussion, we explore the questions that have concerned philosophers for more than two thousand years — questions that remain unanswered.
