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.

Death: Embracing the Last Transition
As a society that fears death, we tend to avoid the subject. But the key to having a positive end-of-life experience might come in doing just the opposite. On this episode, we’ll hear from philosopher Simon Critchley, Boston-area chaplains Ruth Delfiner, Sarah Byrne-Martelli, and Maude Quinn, and Threshold Choir singer Leigh Davis about what makes a good death, and the many rituals, spiritual or secular, that ease our transition out of this world.
Simon Critchley is the author of many books about death, including The Book of Dead Philosophers and How to Stop Living and Start Worrying. Find out more about his other work, including his most recent book, Bald, on his website.

Midlife: Leaning Into the Change
Data shows that for many people, happiness takes a big dip around 50. But aging doesn’t have to be a crisis if we can figure out how to embrace who we’re becoming rather than hanging on to who we used to be. If done right, midlife can actually be a time of deepening joy and satisfaction. Join Dave as he talks to The Atlantic columnist Arthur C. Brooks and Swami Tyagananda, head of Boston’s Vedanta Society, about how to move into the second half of our life with grace.

Relationships and Marriage (Part 2): Keeping the Fire Burning
To hear Hollywood tell it, good sex is a clothes-ripping race to the finish line, often between people who barely know each other. But the version we’re getting from movies and pop culture isn’t what it takes to build real intimacy, trust, and connection in the long term. On this episode, we’ll talk to Rachel Alba, a clinical sexologist with a master’s in theology, about the connection between sex and spirituality, and why exploring that link may be key to developing a deeper, more fulfilling relationship with your partner, and maybe even the divine.

Relationships and Marriage (Part 1): Finding the Right Balance
The definition of a “good” marriage has changed drastically over time and today it seems our expectations for our partner are higher than ever. We want a best friend, intellectual equal, lover, and for many, a sensational co-parent who can also touch our soul. Which is a lot of pressure to put on one person! On this episode we'll talk to psychologist Eli Finkel, author of The All or Nothing Marriage, about the history, workings, and complications of wedded bliss. We’ll also hear about why the secret to a healthy marriage might not be what you think, and how intimacy might be an important way to meet even our spiritual needs.

Adolescence: How to Build an Adult

Join Dave as he talks with psychologist Leah Somerville and religion scholar Connor Wood to explore the adolescent mind and how rituals can help it learn to “adult.”

Childhood: Growing the Moral Muscle
Do children need religion to grow into ethical, caring adults? Sixty-five percent of Americans think so, but the relationship between religion and morality is a nuanced one.

Birth: Getting Off to Good Start
For all the joys a new child brings, it can also be a trying time filled with stresses, worries, and for some, depression. Long before new parents turned to books and blogs for advice, they turned to traditional practices and community for support. Join Dave as he speaks with neuroscientist Lisa Feldman Barrett and psychologist Andi Clements to explore how religious practices big and small can help parents bond with their babies, reduce their stress, and even ward off postpartum depression, AND how anyone can use the wisdom of those practices in their own lives when children arrive.
