Ecological Ethics and the Human SoulIn Ecological Ethics and the Human Soul: Aquinas, Whitehead, and the Metaphysics of Value, Francisco J. Benzoni addresses the pervasive and destructive view that there is a moral gulf between human beings and other creatures. Thomas Aquinas, whose metaphysics entails such a moral gulf, holds that human beings are ultimately separate from nature. Alfred North Whitehead, in contrast, maintains that human beings are continuous with the rest of nature.
