In this episode of Love & Understanding, I sit down with philosopher Jeremy Shearmur, who worked closely with Karl Popper for nearly a decade, to explore what it means to live in an “open society.”

We begin with Popper’s central insight: that knowledge is always provisional, and that progress depends on our willingness to be wrong, to receive criticism, and to revise our beliefs. From there, we examine how these ideas extend beyond philosophy into politics, institutions, and everyday life.

Together, we explore:

-The tension between certainty and fallibility

-The moral and epistemological foundations of an open society

-The rise of polarization, populism, and distrust in institutions

-How social media shapes (and distorts) our search for truth

-The role of criticism, pluralism, and intellectual humility in a functioning democracy

Shearmur also offers a rare, personal look into Popper as a human being—brilliant, driven, and deeply imperfect—and reflects on the challenges of embodying philosophical ideals in real life.

This is a conversation about truth, error, and the fragile conditions required for a society to remain open, self-correcting, and free.

In this episode, John speaks with Britt Hartley. Britt is the author of a #1 bestseller in secular spirituality. Her book is titled No Nonsense Spirituality. Britt has a masters degree in theology. She considers herself a secular spiritual director, sufi mystic, nihilism survivor, religious deconstruction coach, and a Program Director for Spiritual Direction Training.

Britt was a blast to speak with. She has one of the most brilliant minds I’ve come across. She expresses herself with both a humility and a confidence. I am grateful to have her as a leader in this space, especially to keep her male counterparts in check. I learned a lot from our conversation, and I hope you do too.

In this episode, John explores the mind-state of effort, which is the most common translation from the Pali word "virya." Virya is one of three mind-states, along with concentration and mindfulness, the Buddha singles out for us to cultivate in his Noble Eightfold Path, which is a kind of training program to bring peace of heart and mind not only to ourselves but to the world around us.
