Every action which is wrong is also an action which ought not to be done and which it is our duty not to do; and also, conversely, every action which ought not to be done, or which it is our duty not to do, is wrong. These three negative terms are precisely and absolutely coextensive. To say that an action is or was wrong, is to imply that it ought not to be, or to have been, done; and the converse implication also holds. But in the case of “right” and “ought,” only one of the two converse propositions holds. Every action which ought to be done or which is our duty, is certainly also right; to say the one thing of any action is to imply the other. But here the converse is not true; since, as we have seen, to say that an action is right is not to imply that it ought to be done or that it is our duty: an action may be right, without either of these two other things being true of it. In this respect the relation between the positive conceptions “right” and “ought to be done” is not on a par with that between the negative conceptions “wrong” and “ought not to be done.” The two positive conceptions are not
