Chaos & Catharsis
Chaos & Catharsis
At the Irvington Presbyterian Church, 25 N Broadway, Irvington, NY 10533.
The evening opens in conversation with Jeremy Lent, whose work explores how the stories we tell ourselves about the world have shaped the course of civilization. Drawing on history, philosophy, and ecology, he brings the metacrisis into focus while pointing toward a different possibility: an ecocivilization rooted in connection, balance, and shared flourishing.
Following the presentation, the room will shift from listening to relating. Participants will be invited into a simple, guided exchange to connect more directly with one another. We’ll then move into music, with Nick Demeris leading us in a participatory song circle that will transform the group into a shared instrument.
Jeremy Lent
Jeremy Lent
Jeremy Lent is an interdisciplinary author and systems-thinker whose work bridges history, philosophy, cognitive science, and ecology to examine how cultural worldviews shape the course of civilization. He is the author of The Patterning Instinct: A Cultural History of Humanity’s Search for Meaning, which traces the structures of human meaning-making across cultures and eras; The Web of Meaning: Integrating Science and Traditional Wisdom to Find Our Place in the Universe, which offers an integrative, life-affirming framework for rethinking humanity’s relationship with each other and the living world; and the forthcoming Ecocivilization: Making a World that Works for All, which lays out a practical and visionary case for transforming today’s extractive systems into a civilization grounded in ecological balance, justice, and mutual flourishing. Through his writing, speaking, and leadership, Lent has become a leading voice on the cultural roots of the metacrisis and the possibilities for deep transformation.

April 25th "Earth Church" Performance Reverend Billy and the Stop Shopping Choir
April 25th "Earth Church" Performance Reverend Billy and the Stop Shopping Choir
Reverend Billy and the Stop Shopping Choir are unlike any other act: part gospel-infused performance, part political spectacle, part communal call to conscience. Led by Reverend Billy Talen, they use song, humor, theatricality, and moral clarity to challenge consumerism, ecological destruction, and the cultural forces that keep people disconnected from what matters most. Their work is bold, funny, and deeply participatory, creating the kind of charged collective experience that helps people move from passive concern to feeling, connection, and action. Buy tickets and reserve your seat.

Collapse and Renewal
We are happy to share the launch of Chaos and Catharsis: Minds, Movement & Music for Uncertain Times.
Building on past Climate Talks, C&C is a speaker-led series for a time of converging crises: climate disruption, economic instability, democratic stress, technological risk, inequality, polarization, and deepening loneliness. Each talk is coupled with a regional organization, like Indivisible, offering concrete ways to engage in solutions on the ground. Our events end with a facilitated song circle to bring the room into resonance. We aim for each gathering to leave you more informed, grounded and connected to others, and more resourced for the times we are in.
Luke Kemp and Douglas Rushkoff will discuss Luke’s new book Goliath’s Curse, bringing historical perspective and cultural insight to the intertwined crises of our time. Their conversation will explore what the rise and fall of past societies can teach us about the pressures facing our own moment, while also pointing to pathways forward and the reasons for guarded hope that can still be found in this period of upheaval.
This will be followed by a brief overview from Lisa Genn, who serves on the Steering Committee for NYCD16/15 Indivisible, on concrete ways to engage in and support democratic participation, immigrant justice, and other on-the-ground community efforts. The evening will close with an embodied practice for grounding and connection led by Samantha Sweetwater.
Presbyterian Church, April 17th, 7:00–9:00 PM. Tickets required.

When you arrive at the nature center, turn your iPhone screen red to preserve night vision! This is helpful to allow your eyes to accommodate to the dark, reduces glare, and is less disruptive to wildlife. I didn’t even know this was possible to do with the iPhone, but this is an amazing trick for astrophotography.
