In a number of recent publications, Douglas Portmore has defended consequentialism, largely on the basis of a maximizing view of practical rationality. I have criticized such maximizing views, arguing that we need to distinguish two independent dimensions of normative strength: justifying strength and requiring strength. I have also argued that this distinction helps to explain why we typically have so many rational options. Engaging with these arguments, Portmore has (a) developed his own novel maximization-friendly method of explaining the ubiquity of rational options, and (b) criticized one argument in favour of a substantive justifying/requiring distinction in the domain of practical rationality. The present article defends the justifying/requiring distinction, and criticizes Portmore's maximization-friendly strategy for explaining the ubiquity of rational options.

In brief, the criticisms were based on the fact that I wrongly focused on either/or choice situations, which ignored the relevance of additional alternatives. In more recent work I have acknowledged the merits of these criticisms. But I have also modified my view so that rational assessment takes all available alternatives into account. As a result, the criticisms no longer apply.

12 Michael Slote, whom Portmore cites with approval, essentially does this by defining moral reasons as ‘considerations having argumentational force toward one or another moral conclusion’, though Slote himself later ignores this definition. See Slote, Michael, ‘Kagan's, ShellyThe Limits of Morality’, Philosophy and Phenomenological Research 51 (1991), pp. 915–17CrossRefGoogle Scholar. Similarly, Michael Bratman – whom Portmore also cites with approval – countenances talk of reasons as being moral if ‘they, among others, count in determining the moral balance’. See Bratman, Michael, ‘Kagan on “The Appeal to Cost”’, Ethics 104 (1994), pp. 325–32CrossRefGoogle Scholar.
13 For those worried about the substantive claims here, it may be worth noting that Portmore's definition of ‘more morally requiring strength’ (Portmore, Consequentialism, p. 121) agrees with common sense in giving the reason to prevent blindness more such strength than the reason to prevent someone's car from being towed.

17 Portmore, ‘Perform’, p. 448. C-PYBO is potentially confusing in suggesting that an agent might have more reason to perform one optimal maximal option than another. But here Portmore is talking about restricted optimal maximal options: maximal options that are the best one can do given that one performs a certain act.
