Abstract

Neo-Aristotelian ethical naturalism suggests that the sense of normative terms like “ought” and “good” as they appear in ethical discourse is to be elucidated in terms of the relation in which a living individual stands to the life-form or “species” of which it is an exemplar—in our case: the human life-form. A theory of this form has to provide a story about questions such as: What enables us to distinguish the different kinds of life within the theory? What makes them, despite those differences, all sorts of natural goodness? And where, in relation to those continuities and discontinuities, is the account of practical reason to be situated? In this paper, I investigate how a developed ethical naturalism has to conceive of the relation between the genus concept life and the concept of the specific kind of life characteristic of us: rational or practically self-conscious life. I argue that there is a deep ambiguity with respect to this question in the account Philippa Foot presents in Natural Goodness. An ambiguity that covers a dilemma. A properly developed ethical naturalism would have to develop the concept of reason out of the reflection on life.
