Abstract

The theist thesis that any true ethics must be a religious one is criticized from two different angles; it is shown that: (i) in order to avoid divine voluntarism, theism uses a supposition the acceptance of which makes arguments against autonomous ethics un- acceptable, for they inevitably beg the question; (ii) it assumes a kind of moral foun- dationalism which is, according to some Wittgensteinean arguments, utterly superfluous; the idea that any authoritative ethics needs the absolute authority of God can thus be shown to be unjustified
