Abstract: This paper is concerned with the relationship between knowledge-how and a family of success in action notions, namely, skills, abilities, dispositions, and intentional actions. The nature of this relationship is puzzling. For example, one reason it is puzzling is that some considerations suggest that knowledge-how is the explanatorily basic notion—that can be used to explain successful actions, and skills and abilities to so succeed—whereas other considerations suggest exactly the opposite. My aim here is to explore one way in which these puzzles might be resolved within a broadly intellectualist approach to knowledge-how. I offer a novel version of intellectualism called practical attitude intellectualism, and I illustrate how this view can be used to illuminate and solve these puzzles. This view is also of interest because it shows us how to reconcile intellectualism with the Rylean claim that knowledge-how is a complex dispositional state.
