  An instrumentalist attempts to meet Wolff's challenge by saying that an authority is legitimate when one complies better with one's duty overall by submission to authority than by trying to act on the basis of one's own assessments of what is right and wrong in each instance. This amounts to a rejection of the duty of autonomy that is central to the anarchist idea. Or at least it is a rejection of the idea that the duty of autonomy is the most fundamental duty. But it does get at something important. Wolff's challenge states in a rather general way the worry that there is something immoral about failing to critically reflect about what one ought to do in each instance of action. And he states that submitting to the commands of the state is precisely a case of failing to act on one's critical assessment of a situation. The instrumentalist suggests a way in which it is not immoral to fail to critically reflect on one's prospective actions in each instance. Indeed, the instrumentalist can argue that it is sometimes immoral to insist on critically reflecting and acting autonomously when one may actually act worse as a result of consistently critically reflecting. We frequently act on the basis of rules of action, without considering all the details of the circumstances in which we act on the grounds that trying to take all the details of each situation into account for each action would produce bad decisions. The instrumentalist argues that we ought to take this kind of attitude to the commands of the state when we will better act in accordance with our duty overall by doing so than by attempting to make independent assessments of the worth of our actions in every case (see Raz 1986, ch. 3.)
