A Just Eudaimonia: The Everyday Fabric of a Shared Life and the Praxis of Flourishing

This paper, the eleventh in the series, develops the empirical praxis of the good relation whose conditions the prior paper set out in the abstract: that a good relation is cultivated as a field rather than constructed as a structure, that the field's matter is the everyday sensory and habitual fabric of a shared life, and that a good field is at once eudaimonic and just, the just constituting rather than merely constraining the eudaimonic. It asks how a shared life is in fact cognised, practised, assessed, and sustained, and treats its course as a cycle — cognition, practice, evaluation, reflection, and renewed cognition — turning from a relation's beginning, through marriage, into its later years. The cycle is a real dynamical cycle, not a sequence of stages: its persistence is the condition of the relation's existence, so its cessation is not a relation at rest but a relation extinguished. Five frameworks for the cognition and practice of flourishing — the positivist, evidentialist, normative, virtue-theoretic, and phenomenological — are treated not as rival theories of one measurable object but as the symmetry-broken phases of an object no single framework possesses. Appraisal, before it is explicit measurement, is continuous and largely unconscious inference upon the partially observable state of a relation, formalised as the belief-updating of a decision process whose objective is revised by its own running; on a free-energy reading, this continual appraisal is the activity by which a relation holds itself in existence. Three commitments run through the paper. First, an operational concession: where it must assess, it restricts to value structured into an assessable proxy, marking openly that the proxy is not the irreducible value of the prior papers. Second, justice is given a statistical signature: the distribution of returned value, against a coupling-based baseline, has a skewness by which the exploitation of one party within an apparently satisfying relation becomes visible where aggregate satisfaction conceals it. Third, the cycle accumulates a phase (holonomy), and its regime is fixed by whether it persists and what sign of phase it accumulates — giving three regimes: the flourishing spiral, the catastrophic cycle, and extinction, with bifurcations between them. Justice is shown to be the internal condition of the flourishing spiral, not a constraint upon it. The paper ends in plural conclusions: flourishing is cultivated and not constructed, assessed in proxy and not possessed, sustained as an open spiral and not secured as a state.
