Bioethics as bios ethikos

Drawing on a genealogical analysis of the distinction between zoē (biological life as organic functioning) and bios (a distinctively human way of life shaped by meaning, orientation, and evaluative practice), the article reconceives bioethics as bios ethikos: ethical reflection on the conditions under which forms of life become meaningful and inhabitable. It introduces the notion of the existential remainder to describe the ethically significant dimensions that persist when institutional deliberation leaves aspects of lived existence under-articulated. The article proposes a renewed structural orientation grounded in the heuristic formula T = PEWS + C. Ethical thinking (T) is distributed across four interrelated domains of lived existence: Person, Earth, Work, and Society (PEWS), while the addition of C designates the creative openness that resists full institutional codification. PEWS-oriented evaluation may be operationalised through more integrative assessment tools, while maintaining vigilance toward the irreducible horizon of existential creativity. Bioethics, thus reconceived, becomes not only the regulation of life, but reflection on whether the governance of life sustains the conditions under which life can remain meaningfully lived.
