This article has three parts. The first two explore contemporary philosopher Bonnie Kent's important contributions to the role of the weakness of the will in actions of the morally incontinent in Thomas Aquinas treatment of human action. While Kent's treatment gives many important insights, nevertheless, she fails to recognize that the weakness of the will does in fact have role in the actions of the morally incontinent. Kent is correct that, for Aquinas, the passions cause the incontinent act to act as such. She fails, however, to recognize that the role of the passions does not exclude the weakness of the will as a cause, and even a principal cause. The third part takes up the criticisms of Gary Watson to which Kent's remarks were meant as a reply and shows that even with the causative role of the weak will, Aquinas' account does not fall prey to Watson's criticisms.
