What if gratitude isn't just good manners, but measurably changes your wellbeing? What if the medieval Christians were right about nature being alive, and we've spent the last 400 years getting it fundamentally wrong? And why are half a million people now walking ancient pilgrimage routes across Europe when rationalist materialism promised to free us from such "superstitions"?

In this wide-ranging conversation at Hampstead Parish Church, I explore these questions with Dr. Jessica Harland, touching on everything from my early crisis of conscience in a vivisection lab to discovering LSD at Cambridge, from the Protestant Reformation's assault on pilgrimage to why your GP should probably be prescribing forest walks. We go into the scientific evidence behind spiritual practices—yes, there are thousands of peer-reviewed studies—and discuss why saying grace before meals, walking to holy places, and reconnecting with the living world aren't quaint relics of the past, but practices our secular age desperately needs to rediscover.

Whether you consider yourself religious, spiritual-but-not-religious, or simply curious about why these ancient practices refuse to die, I hope you'll find something here that sparks your imagination—and perhaps your own spiritual journey.

Recorded at The Parish Church of St John-at-Hampstead, October 2025. If you're in London, I highly recommend coming by to experience choral evensong.
