A defence of the possibility of amoralism is important to discussions about the foundations of ethics and the justification of morality. I argue against Michael Smith's attempt to show, through a defence of internalism, that amoralism is incoherent. I argue first, that a de dicto reading of the externalist's explanation of changes in motivation which are pursuant upon changes in judgement is not objectionable or implausible as Smith contends; and second, that internalism cannot account for the effort of the will required to make such changes in motivation. I also argue that the internalism/externalism debate can be diffused by considering the epistemic difficulties associated with identifying motivating states and by rejecting the notion that motivation can be understood in terms of psychlogical states.
