Aristotle bequeathed to us a powerful metaphysical picture, of substances in which properties inhere. The picture has turned out to be highly problematic in many ways; but it is nevertheless a picture not easy to dislodge. Less obvious are the normative tones implicit in the picture and the way these permeate our system of values, especially when thinking of ourselves and our ambitions, hopes and fears. These have proved, if anything, even harder to dislodge than the metaphysical picture which supports them. This paper first draws out the ethics suggested by a conception of being as individual substances, and finds both inner tensions among these values—expressed in divergent characteristics in the history of philosophy—and a neglect of a significant set of values. Substance metaphysics prefers freedom, independence and autonomy over relational and reciprocal values, which can even be regarded as existentially threatening. A prominent attempt to accommodate both sorts of values without eschewing substantialist metaphysics is briefly considered, before turning to examine an alternative metaphysics and the values it implies. A metaphysics which takes being as becoming, it is argued, supports an ethics centred on relational values, and their associated virtues of care.
