This volume, originally a special issue of the Journal of Consciousness Studies, uses the recent writings of Philip Goff as a jumping-off point for discussions of panpsychism -- the idea that consciousness is a fundamental and pervasive aspect of our universe that cannot be understood in other, more basic, terms. The contributors to this book explore various issues of panpsychism from the perspectives of science, philosophy, and theology. Some papers focus on further motivating and developing the panpsychist position. Others explore various challenges that the panpsychist faces. Collectively, they shed new and important light not only on panpsychism, but on the fundamental question of the place of consciousness in nature more generally.
