Assuming these definitions, is there a coherent notion of acting from duty that makes it coextensive with acting from character?
Update: I mean to ask a basic question. Actions that proceed from passion are by definition teleological. They aim to cure a lack. This aim preempts their capacity for answering to principle regardless of anticipated outcomes. By contrast, answerability to principle is a general condition of modern deontology, as distinct e.g. from its classical theological construal in the manner of Augustine’s “Dilige, et quod vis fac.” On the other hand, by making allowances for supererogation, even the deontologist leaves room for accommodating diverse norms of character. (Here I am construing character broadly, as ἦθος rather than ἕξις.) So the duty in regard to a certain course of action may be perfect or imperfect, depending on its mandate by the agent’s character. Thus even in the absence of a conflict of duties, it is possible to accommodate individual differences of principle.
