The Architecture of the Human Moral Subject: Rethinking Personhood, Organismhood, and Human Rights

Abstract

Contemporary debates concerning abortion, euthanasia, disorders of consciousness, and emerging biotechnologies frequently depend upon the concept of personhood. Yet personhood performs multiple philosophical functions simultaneously: it identifies the subject of psychological explanation, serves as a criterion of moral status, and often determines legal recognition. This conceptual overextension has contributed to persistent disagreements regarding the beginning and end of human life. I argue that these controversies arise, in part, from conflating three distinct dimensions of subjecthood that belong to different explanatory domains. The article develops a triadic framework distinguishing biological subjecthood, psychological subjecthood, and legal subjecthood. Biological subjecthood identifies the continuous human organism that persists throughout development. Psychological subjecthood concerns the organization of agency through capacities such as consciousness, intentionality, self-awareness, and autonomous decision-making. Legal subjecthood specifies the institutional recognition of rights and obligations within particular political communities. Rather than competing with one another, these concepts answer different philosophical questions and should not be expected to perform the same explanatory function. Building on this framework, I propose a corresponding architecture of rights consisting of existential rights, agentic rights, and institutional rights. Existential rights protect the continued existence and bodily integrity of the human organism; agentic rights govern the autonomous exercise of freedom and responsibility; institutional rights regulate participation within legal systems. This architecture preserves the universality of human rights while accommodating developmental changes in psychological competence without making moral membership contingent upon contested definitions of personhood. The framework is then applied to abortion, emerging reproductive technologies, physician-assisted dying, and postmortem dignity. Rather than resolving these controversies by determining whether particular individuals qualify as persons, the proposed account reframes them as questions concerning the balancing of rights among members of an already established moral community. I conclude by arguing that distinguishing biological, psychological, and legal subjecthood provides a more coherent conceptual foundation for both philosophy of psychology and contemporary theories of human rights.
