    • The argument is easily extended to cover responsibility for bad events as well (e.g., the negligent engineer's responsibility for the bridge's collapse), taking this to be a function of responsibility for bad actions leading to them. On these and related cases, see Holly Smith, Culpable Ignorance, Philosophical Review 92 (1983): 543-71, at 552-55 and 564ff. For simplicity I will focus just on responsibility for bad actions.

    • As Rosen notes, all ignorance is, or implies, normative ignorance inasmuch as even ordinary circumstantial ignorance leads to a failure to appreciate the truth about the balance of reasons in connection with the action (Skepticism about Moral Responsibility, 304). I shall follow him in distinguishing between this sort of derivative normative ignorance and basic normative ignorance, such as ignorance of moral principles, which latter will be discussed further below.

His hiding his bad behavior was thus consistent with his acting nonakratically

    • Our knowledge of the occurrence of akrasia does not, of course, approach anything like Cartesian certainty. This is not a problem, however, as Rosen is not relying on such overblown epistemic standards in his argument. If he were, then the obvious response would be just to grant the argument right up through step ix, and even the first part of the conclusion, and then simply to reject the final part of the conclusion about suspending judgments of responsibility: for there is no reason to think we should suspend our judgment about something just because we lack Cartesian certainty. Thanks to Jim Klagge for this point

    • Ibid, 305. When I say that Potter's case does not plausibly fall into the category of genuinely hard cases in morality, I mean this in relation to his cultural context, which I am taking to be roughly our own. Something can in this sense count as a hard case in one cultural context or time but not in another. Slavery, for example, is even further from being a hard case at present, but, as discussed in a note below, it may have been a genuinely hard case for someone in Aristotle's circumstances, where even reasonable efforts at critical reflection may not have sufficed to make the moral facts clear. We might also speak of some cases as intrinsically hard cases, meaning that they remain difficult even for ideally informed and reflective agents because of a real balance of competing legitimate moral considerations. I shall here mostly set aside cases of widespread, culturally based moral ignorance

    • This case thus contrasts with a case such as ancient Greek views on slavery. As Benson points out, in the latter case, the very practice of slavery typically limited severely the evidence about slaves' moral dignity that some in the society, especially aristocrats like Aristotle, could be expected to have access to, His aristocratic social circumstances may have occluded his access to good evidence about the rational capabilities of persons subjected to enslavement, thus preventing him from being able to discern those capabilities Benson, Culture and Responsibility, 611, Without going into the merits of this particular claim, I think it is clear that it would be implausible to claim any similar cultural occlusion of relevant evidence in the case of the contemporary ruthless businessman, for reasons I go on to develop in the text

    • For an argument that many cases of wrongdoing stemming from normative ignorance involve affected ignorance and are thus culpable, see Moody-Adams, Culture, Responsibility, and Affected Ignorance. Moody-Adams seems, however, sometimes to conflate Aquinas's idea of affected ignorance with the other form of ignorance he distinguishes from it (described below in the text, For example, the fourth form of affected ignorance Moody-Adams distinguishes (301-2, where an agent fails to acknowledge her fallibility and so is ignorant of this and thus led into further ignorance (e.g, bigotry) and error (e.g, suppressing protest of bigotry, is not really affected ignorance in Aquinas's sense: it is not ignorance resulting from a choice to remain ignorant as such as in her examples of deliberately making sure one does not get certain unwanted information or Aquinas's example of wanting an excuse to continue sinning, but ignorance resulting from bad choices exhibiting a certain cha

The latter sort of ignorance will be important to my discussion below.

    • Why not throw out the original/derivative distinction altogether and just say from the start that Potter is originally responsible for his bad business practices? The reason is that we cannot understand why he is culpable for these actions without appeal to the fact that he is operating from ignorance that is culpable because at various times in the past it would have been reasonable to expect him to have done certain epistemically relevant things differently. He is responsible for the bad present behavior only because he is responsible for something else in the past. By contrast, I have argued that, when we are assessing those earlier epistemically debilitating choices themselves, things are different: we can understand the relevant claims about reasonable expectation without appeal to reasonable expectations in connection with even earlier past behavior

    • It will not do to claim that premise iii is just stipulative. One cannot just stipulate what is in fact a substantive claim that the only way to be directly responsible for a bad action (as opposed to being responsible for it by being responsible for something else) is to do it despite knowing the balance of reasons against it. And if one did that, treating originally responsible as a technical term subject to that stipulation, then this would just raise new difficulties for premise i, which would now just leave out some relevant possibilities in a question-begging way (namely, the possibility argued for in the text, of direct responsibility for certain epistemically debilitating choices without akrasia).
