Practical Knowledge
This chapter discusses the argument of Sections 44-48 of G.E.M. Anscombe’s Intention. It begins by situating her appeal to the concept of practical knowledge in relation to the philosophy of Thomas Aquinas. Following this, the chapter shows how several elements in Aquinas’ account are drawn on by Anscombe in her argument that an agent’s self-knowledge of her act is “the cause of what it understands”. It is argued that Anscombe meant to characterize an agent’s practical knowledge as both formal and efficient cause of its object. Finally, the chapter considers whether Anscombe succeeds in defending her thesis that intentional action is necessarily known without observation. Here it is argued, first, that knowledge of one’s act is not a strict requirement of doing something intentionally, and second, that the role of observation in an agent’s self-knowledge is different from that of evidence in observational knowledge of the world.
