Polytropolis is a personal essay newsletter by a philosopher of mind who writes about AI consciousness, moral status of machines, and related philosophy, with digressions into games and science fiction. Readers get careful, opinionated arguments engaging with current debates and with fiction such as Ted Chiang's work.

Long-form essays on consciousness, culture, myth, religion and technology from a California perspective, written by the host of the Expanding Mind podcast. Issues mix cultural criticism, philosophy and personal reflection, such as a reading of AI discourse and a take on the Odyssey through Adorno and Jung.

Rob Brezsny's newsletter offers astrology-flavored essays, horoscopes and excerpts from his books, written in a lyrical, playful and personal voice. Readers get reflective pieces on emotions, spirituality, consciousness and imagined hopeful futures.

Personal reflections on consciousness, dreamwork, healing and helping, drawing on the author's lived experience including recovery after a cardiac arrest. Readers get contemplative essays built around a framework called Orange Harmonics, which treats consciousness as visible in the relationships within lived experience.
