David Albert is the Frederick E. Woodbridge Professor of Philosophy at Columbia University, where he directs the Philosophical Foundations of Physics program. Tim Maudlin is Professor of Philosophy at NYU. Both David and Tim are renowned as leading philosophers of physics, though their work extends beyond that to the philosophy of science and metaphysics. David is a prior guest (episodes 23 and 30) of Robinson’s Podcast, as is Tim (episode 46). David, Tim, and Robinson discuss the foundations of quantum theory, beginning with its historical motivation, tracking through some important concepts—superposition and the measurement problem—and then exploring some of its philosophical aspects (such as determinism, realism, the potential for backward causation, and more).
