Choose whichever you like—standard utilitarianism, Rawls’s theory of justice, attempts to ground moral thinking in evolutionary biology or neurophysiology—you will always find, if you subject your preferred ethical naturalism to sufficiently unflinching scrutiny, that at some primal and irreducible point it must simply presume a movement of good will, an initial moral impulse that, with a kind of ghostly Gödelian elusiveness, can never be contained within the moral system it sustains. All the polyphony of nature falls mute when asked to produce one substantial imperative, unless one believes (explicitly or tacitly) that the voice of nature has its origin and consummation in the voice of God.
