 This objection could be overcome if one could argue that it is unlikely that there are many unknown goodmaking properties. For if the number is small, then the probability of Q may still be high even if Q does not express a law, or a consequence of a law. Moreover, I am inclined to think that it may well be possible to argue that it is unlikely that there are many unknown, morally relevant properties. But I also think that it is very likely that any attempt to establish this conclusion would involve some very controversial metaethical claims. As a consequence, I think that one is justified in concluding that such a line of argument is not especially promising.
