The passion of despair, according to Thomas Aquinas, is an appetitive movement away from a future arduous good that is impossible to attain. Criticism of his account of despair abounds. Nicholas Lombardo argues that despair cannot be proper passion because the appetite cannot move away from a good. Eric D'Arcy and Susan James argue that Aquinas's description of passions as movements casts doubt on his understanding of some passions, including despair. Michael Miller and John Patrick Reid deny that despair can be morally praiseworthy and conducive to action. In this paper, I defend Aquinas's account of the passion of despair from these criticisms.
