 Thus, an akratic person knows actually that what he is about to do is a sin, but his knowledge is theoretical and lacks the experiential affective aspect. By contrast, he finds the sinful action pleasant because his thought concerning it has this aspect to it (Bobillier 2020, 257–58; Summa II q. 86, p. 193). To be sure, even this experiential mode of thinking does not determine the will, and thus an akratic can always decide to do otherwise, and he is fully responsible for his choice. Olivi criticizes the Aristotelian theory for taking away the responsibility due to a momentary lack of understanding, caused by emotion (see e.g. Bobillier 2020, pp. 254–56). In the end, there is no other explanation for bad choices except that the person wills to make them.
