Abstract

I develop a theory of personal ontology called normative pragmatic selfhood (NPS) to explain what persons are and how they are morally valuable. I also demonstrate the applicability of NPS theory by using it to assess the moral status of marginal cases in bioethical dilemmas. I begin by discussing the concept of intrinsic value and why it is problematic when it comes to persons. I then draw upon John Dewey’s theory of value, specifically the concept of growth, and Kant’s concept of humanity to show that persons are objectively yet extrinsically valuable. Next, I discuss and argue how the psychological and narrative theories of identity are unable to justify the value of persons and how NPS theory succeeds in doing so. I conclude by showing how the application of NPS theory to marginal cases offers one way of thinking through these difficult bioethical issues.
