  A further criticism of the Open Question Argument comes from William Frankena (1939). Frankena worries that the Open Question Argument begs the question at issue. “Is such-and-such, which is \(N\), good?” is an open question precisely when a definition of \(N\)-ness in terms of goodness is not an analytic truth—and that is precisely what Moore is trying to establish. Moore seems to owe us more support than has been given for the claim that all questions concerning natural-moral identities are open.
