 On the other horn of the dilemma, the internalist claim is philosophically interesting but false. Here, Roskies argues that persons with injury to the VM cortex are a “walking counterexample” to internalism. As Roskies describes them, such patients “appear cognitively normal on a wide spectrum of standard psychological tests, including those measuring intelligence and reasoning abilities”, however, they “all appear to have particular difficulty in acting in accordance with social mores despite their retained ability to judge appropriately in such situations” (56). The condition of these patients has been referred to as “acquired sociopathy”. According to Roskies, VM patients are able to “reason morally at a normal level” and their moral claims “accord with those of normals”, but they fail to reliably act as normal persons do and, what’s more, “seem to lack appropriate motivational and emotional responses” (57). VM patients do not exhibit the skin-conductive response (SCR) to emotionally-charged stimuli that normal persons exhibit, which Roskies take to be evidence of the absence of motivation. VM patients allegedly present a counterexample to motive-internalism because they have mastery of moral terms and appear to make sincere moral judgments, while lacking any motivation to act in accordance with them (59).
