How God Works: The Science Behind Spirituality
While religion and science often seem at odds, there’s one thing they can agree on: people who take part in spiritual practices tend to live longer, healthier, and happier lives. The big question is: Why? In How God Works, professor Dave DeSteno takes us on a journey to find out how spirituality impacts our minds and bodies, as well as the world in which we live.He speaks to leading scientists and philosophers, religious thinkers, and thought leaders to explore what we can learn from the world’s faith traditions to help us meet some of life’s biggest challenges. Along the way, he’ll look at how we can adapt and use spiritual practices in our own lives, whatever our beliefs, including none at all.It’s by working across the boundaries that usually divide us – science versus religion, one faith versus another – that we’ll find new ways to make life better for everyone.

The Conscious Cosmos
For centuries, Western science and philosophy have struggled to explain what consciousness is and where it comes from. What if the answer to both those questions is: everything?On this episode, we dive into panpsychism: the idea that consciousness may not be limited to humans, or even living beings, but could be a basic property of reality itself. We’ll talk to philosopher Philip Goff about why this idea is gaining attention in academic circles, and to theologian Joanna Leidenhag about how panpsychism aligns with spiritual traditions from across cultures and throughout history. We’ll also ask: could this strange-sounding idea reshape how we understand ourselves and our place in the world?Philip Goff is a professor of Philosophy and the author of Why?: The Purpose of the Universe, Galileo’s Error: Foundations for a New Science of Consciousness and many other publications about panpsychism.

Found By Faith

Data show that these types of experiences happen to about 30% of people. On this episode we’ll talk to one of these people –New York Times columnist and best selling author David Brooks– about his unexpected encounter with faith and what came after.Find out more about Weave: The Social Fabric Project, the non-profit David founded at the Aspen Institute.
