G. E. Moore,
Ethics — Chapter V
(1912)
“ It is very natural, at first sight, to assume that to call an action morally praiseworthy is the same thing as to say that it is right, and to call it morally blameworthy the same thing as to say that it is wrong. But yet a very little reflection suffices to show that the two things are certainly distinct. When we say that an action deserves praise or blame, we imply that it is right to praise or blame it; that is to say, we are making a judgment not about the rightness of the original action, but about the rightness of the further action which we should take, if we praised or blamed it. ”
