 Not self-love but love of others motivates the virtuous person, or what Leibniz calls “disinterested love” (PW, “Codex Iuris Gentium,” p. 171). Metaphysics thus strengthens morality without overhauling it. In revealing that virtue alone ultimately satisfies self-interest, true philosophy guides us steadfastly along the path to virtue. Yet the truly virtuous person performs a morally right action for its own sake.
