 A more subtle line would concede that we do not always use the progressive quite so liberally, but insist that doing so carves nature at its joints. According to Michael Thompson (2008, pp. 91–2, 133–46), intending to do A is not a mental state because it is not static; instead it is a form of imperfectivity or being in progress towards the intentional completion of an act, where the progress may be so vestigial or ineffectual or interrupted that it would be odd to remark, ‘He is doing A.’ (See Thompson 2008, pp. 91–2, 133–45; Moran and Stone 2009, pp. 146–8; Ferrero 2017; Russell 2018.) The unity of prospective intention and ‘doing A intentionally’ is that the latter, too, consists of being in progress, though perhaps with the implication of some success.
