 Rosen’s skepticism here relies on arguments presented earlier in his article for the conclusion that the epistemic requirements on moral responsibility are quite stringent (in order for ignorance to be culpable, it must eventually trace back to clear-eyed akratic action; see also Levy 2011), but for our purposes the important point is simply that “the opacity of mind”, as Rosen puts it, can make it hard to tell when someone is genuinely blameworthy, and thus can render unjustified the judgment of wrongdoing on which appropriate blame rests. Of course, one need not accept Rosen’s skeptical conclusion to agree that blamers must not jump to conclusions about wrongdoing.
