Abstract

In this paper, I argue that ethical normativity can be grounded in the natural normativity of organisms without being reducible to it. Michael Thompson and Philippa Foot both offer forms of neo-Aristotelian ethical naturalism; I argue that both accounts have gaps that point toward the need for a constructive virtue ethics grounded in natural normativity. Similarly, Korsgaard's constructivist ethics ignores the ongoing relevance of natural norms in human ethical life. I thus offer an account according to which the self-shaping activity of human organisms supplements and transforms natural normativity, giving rise to ethical norms. Such an account grounds human ethical distinctiveness in rationality without excluding nonrational humans from the ethical community. In the final section of the paper, I argue that ethical standards can be discovered through human activities, thus allowing for gradual progression in ethical knowledge, both on individual and cultural levels.
