Narrative Unity of a Human Life

In the AI Story

MacIntyre's narrative account is developed against two rivals. The Humean view holds that the self is a succession of experiences with no intrinsic unity — personal identity is a psychological fiction. The Sartrean view holds that the self is radically free at each moment, unconstrained by past commitments. MacIntyre rejects both. The self is a character in a story, and the story provides the unity that neither Hume nor Sartre can account for. "I can only answer the question 'What am I to do?' if I can answer the prior question 'Of what story or stories do I find myself a part?'"

This has three structural consequences. First, human beings are accountable for the narratives of which they are authors — others are entitled to ask how the episodes fit together, what purposes they serve, and whether the life as a whole exhibits coherence. Second, individual narratives are embedded in the narratives of the practices and communities within which lives are conducted — the physician's story is embedded in the story of medicine. Third, practices' narratives are embedded in traditions — the historical arguments about what the practice is for and what excellence within it requires.

The AI moment disrupts all three levels. The individual practitioner's narrative becomes incoherent when the activities that constituted its center are no longer necessary. The practice's narrative becomes unstable when a technology performs the activities around which the practice's arguments were organized. The tradition's narrative faces discontinuity when the accumulated wisdom of practitioners over generations may seem irrelevant rather than foundational. This is the existential dimension of the AI moment that efficiency-focused analysis misses: people are losing not merely jobs but the stories that made their lives intelligible.

The response cannot be the restoration of old narratives; the conditions that made them coherent have changed. The response must be the construction of new narratives that preserve the moral significance of the practitioner's achievements while acknowledging the transformation. The theory of practices provides resources for this: the practice of software engineering is not identical to any particular technology; it is a historically extended argument about what good software is. The new narrative is therefore not a narrative of displacement but of revelation — the revelation that what the practitioner contributes was never the implementation but the judgment, the wisdom, the virtues that the implementation was the medium for developing.

Origin

Developed in After Virtue chapter 15, drawing on hermeneutic and phenomenological traditions (Ricoeur, Gadamer) and on Aristotle's treatment of the unity of the good life in Nicomachean Ethics. Further developed in Dependent Rational Animals (1999).

Key Ideas

The self as character. Personal identity is the unity of a narrative, not a metaphysical substance or a momentary choice.

Three embedded levels. Individual narratives are embedded in practice narratives, which are embedded in tradition narratives.

Accountability to story. We are answerable to others for how our actions fit into the stories of which we are parts.

Existential stakes. Disruption of practice disrupts the narratives that give lives moral meaning.

Narrative reconstruction. After disruption, practitioners must construct new narratives that preserve continuity with the tradition while acknowledging transformation.

Debates & Critiques

Whether MacIntyre's narrative account can accommodate the genuine discontinuities of modern life, or whether it reflects a conservative bias toward continuity. Critics argue that the narrative framework struggles with ruptures; defenders argue that ruptures are precisely what narratives must be able to handle, and that the theory of practices provides the resources.
