Abstract
I argue for a unified theory of knowledge how that is compatible with the reductionist variety of intellectualism: knowledge how is reducible to knowledge that. But, I argue, there are knowledge states that are not justification entailing and knowledge states that are not belief entailing. Both kinds of knowledge state require the possession of practical abilities. I conclude by arguing that the view defended naturally leads to a disjunctive conception of abilities as either essentially involving mental states or as not essentially involving mental states. Only the former kind of ability is a kind of knowledge state, that is, a knowledge how state.
