 Given Mill’s ambivalence between direct and indirect utilitarianism, it is natural to inquire whether one view is more plausible than the other. Some of Mill’s claims in Chapter V suggest a possible advantage that sanction utilitarianism might have. In articulating sanction utilitarianism, Mill claims that it allows him to distinguish duty and expediency and claim that not all inexpedient acts are wrong; inexpedient acts are only wrong when it is good or optimal to sanction them. This suggests that sanction utilitarianism may be preferable to act utilitarianism, because it has a more plausible account of the relation among different deontic categories.
