 Finally, there is Anscombe’s own view, on which there is a normative contrast between intention and ordinary belief. If one fails to act as one intends, and not through a mistaken belief about the means or possibilities for action, ‘the mistake is not one of judgment but of performance’ (Anscombe 1963, pp. 56–7). Intention sets a standard of success for what does. (For discussions of this point, see Frost 2014; Setiya 2016a; Campbell 2018a; Campbell 2018b.) What is more, there is ‘a difference of form between reasoning leading to action and reasoning for the truth of a conclusion’ (Anscombe 1963, p. 60). Intention is justified by the former, not the latter: by practical not theoretical reasoning (Anscombe 1963, pp. 57–62).
