This episode of Spotlights features Matthew David Segall, PhD, Assistant Professor of Philosophy and Religion in the Philosophy, Cosmology, and Consciousness program at the California Institute of Integral Studies. He discusses his new book, Physics of the World-Soul: Alfred North Whitehead’s Adventure in Cosmology (SacraSage Press, 2021), describing the context and key concepts of Whitehead's process philosophy. We reflect on Whiteheadian contributions to debates on a variety of topics, including panpsychism, panentheism, environmental ethics, dialogue between science and religion, and the future of philosophy.
