 Hartshorne’s panpsychism (or psychicalism) entails the belief that each active singular in nature, even those like electrons and plant cells that exhibit feeling if not mentality, is nonetheless a center of intrinsic, and not merely instrumental, value. As a result, Hartshorne’s metaphysics is meant to provide a basis for both an aesthetic appreciation of the value in nature, as well as for an environmental ethics where intrinsic and instrumental values in nature are weighed. In fact, Hartshorne was one of the first philosophers to write in detail on topics in environmental ethics.
