RS 163 - Gregg Caruso on "Free Will and Moral Responsibility"

Release date: July 10th, 2016

Gregg Caruso

If people don't have free will, then can we be held morally responsible for our actions? And what would happen to society if we were to collectively shed our belief in free will? In this episode Julia talks with philosopher Gregg Caruso, who advocates a position of "optimistic skepticism" on the topic. Skepticism because people don't have free will as a sense of moral responsibility, but optimistic because society would be better off if we accept that we do.

RS 162 - Sean Carroll on "Poetic Naturalism"

Release date: June 26th, 2016

Sean Carroll

Naturalism is the stance that everything that exists in the universe arises from "natural" causes, of the sort observable by science -- not supernatural ones. It's practically a foundational tenet of skepticism. But does it imply that there can be no meaning, or purpose, or morality in the universe?

This episode features physicist Sean Carroll, author of the recent bestseller The Big Picture: on the Origins of Life, Meaning and the Universe Itself. Sean and Julia talk about the new "ism" he introduces in the book, "poetic naturalism," and how it attempts to resolve the apparent conflict between science on the one hand, and things like morality, free will, consciousness, and meaning on the other.

RS 161 - Tom Griffiths and Brian Christian on "Algorithms to Live By"

Release date: June 12th, 2016

Tom Griffiths and Brian Christian

Julia chats with the authors of "Algorithms to Live By", about how to apply key algorithms from computer science to our real life problems. For example, deciding which apartment to rent, planning your career, and prioritizing your projects.

In the process, they discuss the assumptions that underlie those algorithms (and what to do about the fact that those assumptions are inevitably violated by the messy real world), and why procrastination might actually be the right algorithm for the wrong problem.
