political philosophy’s hidden assumption: the person

Identity is often treated as though it were the starting point of philosophy. We speak as though persons, objects and institutions simply exist as self-evident entities from which everything else follows. Yet this assumption is remarkably difficult to justify. Across biology, psychology, physics and everyday experience, everything changes continuously. Bodies exchange matter, memories fade, cultures transform and institutions evolve. If identity exists at all, it cannot consist in perfect sameness.

What persists is the capacity to reproduce a particular relational continuity despite continual transformation.

This shifts the foundations of philosophy. Rather than beginning with isolated entities possessing intrinsic properties, we begin with organisation, relation and continuity across time. Identity is not an indivisible substance but an organised continuity maintained through change. Sameness is approximate. Persistence is relational. Identity becomes something continually achieved rather than simply possessed. The question is no longer only, “What is this thing?” but, “How does this organisation continue to reproduce itself despite constant change?” Identity is not axiomatic. It is emergent.

Political philosophy has quietly inherited the person as one of its foundational concepts without making its justification a foundational political question. Hobbes locates personhood in the bearing and representation of action (Hobbes, 1651/1996). Locke grounds it in the continuity of consciousness (Locke, 1690/1975). Kant identifies the person with rational autonomy and moral agency (Kant, 1785/1997). Hegel understands personhood through reciprocal recognition within ethical life (Hegel, 1821/1991). Rawls assumes moral persons capable of forming, revising and pursuing conceptions of the good (Rawls, 1971). Nozick begins with self-owning individuals possessing inviolable rights (Nozick, 1974). Even Parfit, who questions whether personal identity is fundamental, ultimately preserves psychological continuity as the basis for moral concern across time (Parfit, 1984). Together, these accounts differ profoundly in substance yet converge upon a common structural requirement.

Despite their profound disagreements, they each seek a form of persistence sufficiently stable for rights, obligations, responsibility, recognition and political membership to attach across change. They disagree about what persists—memory, rationality, recognition, agency or psychological continuity—but they agree that political life requires a sufficiently persistent bearer. Without such continuity, promises cannot bind, responsibility cannot endure, punishment loses its subject, representation becomes incoherent and rights have nothing to which they may attach.

The person, then, need not be defined in essence before politics can begin. Politics requires only a sufficiently persistent locus of attribution: something capable of bearing a right, incurring an obligation, making a promise, suffering an injury, accepting responsibility or being represented by another. The vessel is functionally indispensable even if its ontology remains unresolved. Personhood can therefore be understood not as a fixed substance but as the persistent relational continuity to which political and legal relations attach.

This relocates the starting point of political theory. The primary question is not simply “What is a person?” but “What conditions allow personhood to persist as the bearer of rights and obligations through continual biological, psychological and social change?” Political institutions should not attempt to exhaustively define the person. They should preserve the continuity through which persons remain recognisable, accountable, protected and capable of participation. The person is not an axiom from which politics is derived, but the persistent relational vessel around which political order is organised.

Democracy depends upon this restraint. It does not require agreement about the ultimate nature of consciousness, identity or the self. It requires institutions capable of recognising persons without reducing them to administrative categories, economic functions, diagnoses, data profiles or inherited classifications. This is particularly significant in Australia, where questions of Indigenous recognition, disability, digital identity, privacy and artificial intelligence increasingly test the boundary between the person and the systems that represent them. A democratic state becomes dangerous when it mistakes its records of a person for the person themselves. Its legitimacy ultimately rests not upon defining personhood, but upon preserving the relational continuity through which persons remain the enduring bearers of rights, obligations and political standing.
