Patrick Todd and Derk Pereboom

Patrick Todd and Derk Pereboom on philosophy of religion and free will.

In this conversation, Todd and Pereboom consider questions about the connection between religion and free will. Does theism imply any particular view of the free will problem? Do certain positions about free will require a theistic justification? Could traditional religion make do […]

Kate Padgett Walsh and Laura Papish

Kate Padgett Walsh and Laura Papish on love and freedom in Frankfurt and Hegel.

Harry Frankfurt defends a view of love of a species of care. In this conversation, Walsh and Papish discuss Frankfurt’s view and compare it to a Hegelian alternative. They begin (1:21) with Walsh’s argument that Frankfurt’s view cannot adequately account […]

Lawrence Krauss and Roy Sorensen

Lawrence Krauss (left) and Roy Sorensen (right) on origins and nothingness.

How did our universe get to be the way it is? Has our universe always existed, or did it arise from nothing? Is it even possible for something to come from nothing? Lawrence Krauss has argued that physicists have discovered some of the […]

Paul Humphreys and John Symons

Paul Humphreys (left) and John Symons (right) on emergence.

A property is said to be emergent if it arises from but is not reducible to some fundamental property (or set of properties). There is a wide range of properties that might conceivably be emergent; consciousness is the textbook example, which might explain why philosophers […]

Tuomas Tahko and Thomas Hofweber

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; […]

Owen Flanagan and Alex Rosenberg

Owen Flanagan (left) and Alex Rosenberg (right) on the significance of naturalism.

Naturalists believe that the world is scientifically intelligible (at least in principle). Thus, naturalists doubt the reality of anything that cannot fit into a scientific worldview. How discomforting are naturalists’ doubts? Can naturalists coherently regard life as meaningful? Rosenberg is happily pessimistic […]

Randolph Clarke and Stephen Kearns

Randolph Clarke (left) and Stephen Kearns (right) on the problem of free will.

It’s not easy to find room in the world for free will. In the first part of this exchange, Clarke and Kearns discuss whether free will can have a place in a deterministic universe. Then (starting at 23:22) they discuss problems […]

Barry Loewer and Tim O’Connor

Barry Loewer (left) and Tim O’Connor (right) on emergence, quantum mechanics, and consciousness.

O’Connor defends, and Loewer opposes, strong emergentism: the view that there are properties and laws beyond those which can be captured by any fundamental physical theory. After clarifying their positions, they discuss (starting at 30:01) whether quantum mechanics supports or undermines […]

Ned Hall and L. A. Paul

Ned Hall (left) and L. A. Paul (right) on causation.

Suzy throws a rock which causes a window to break. That is token causation: a particular event c causes another particular event e. According to a simple counterfactual account of token causation, c is a cause of e exactly if e wouldn’t have occurred […]

Craig Callender and Jonathan Schaffer

Craig Callender (left) and Jonathan Schaffer (right) on meta-metaphysics.

Do mereological sums constitute objects? Questions like this are hotly debated in contemporary metaphysics — yet such questions seem utterly disconnected from science. Has metaphysics gone in the wrong direction? Callender and Schaffer explore the issue.
