Over recent years, there has been a resurgence of interest in arguments favouring intellectualism—the view that Ryle’s epistemic distinction is invalid because knowing how is in fact nothing but a species of knowing that. The aim of this paper is to challenge intellectualism by introducing empirical evidence supporting a form of knowing how that resists such a reduction. In presenting a form of visuomotor pathology known as visual agnosia, I argue that certain actions performed by patient DF can be distinguished (...) from a mere physical ability because they are (1) intentional and (2) knowledge-based; yet these actions fail to satisfy the criteria for propositional knowledge. It is therefore my contention that there exists a form of intentional action that not only constitutes a genuine claim to knowledge but, in being irreducible to knowing that, resists the intellectualist argument for exhaustive epistemic reduction.

You know that George W. Bush is the U.S. president, but you know how to ride a bicycle. What's the difference? According to intellectualists, not much: either knowing how to do something is a matter of knowing that something is the case or, at the very least, know-how requires a prior bit of theoretical knowledge. Anti-intellectualists deny this order of priority: either knowing-how and knowing-that are independent or, at the very least, knowing that something is the case requires a prior (...) bit of know-how. Much of the dispute centers on the relationship between knowing how to do something and having an ability to do it. If having an ability is necessary and sufficient for knowing-how, this is thought to provide comfort for anti-intellectualists. This paper traces the place of ability in the know-how/know-that debate from Ryle's seminal statement of anti-intellectualism through Stanley and Williamson's more recent defense of intellectualism.

What does it mean to know how to do something? This book develops a comprehensive account of know-how, a crucial epistemic goal for all who care about getting things right, not only with respect to the facts, but also with respect to practice. It proposes a novel interpretation of the seminal work of Gilbert Ryle, according to which know-how is a competence, a complex ability to do well in an activity in virtue of guidance by an understanding of what it (...) takes to do so. This idea is developed into a full-fledged account, Rylean responsibilism, which understands know-how in terms of the normative guidance and responsible control of one's acts. Within the complex current debate about know-how, this view occupies a middle ground position between the intellectualist claim that know-how just is propositional or objectual knowledge and the anti-intellectualist claim that know-how just is ability. In genuine know-how, practical ability and guiding intellect are both necessary, but essentially intertwined. (shrink)

In this article I have two primary goals. First, I present two recent views on the distinction between knowledge-that and knowledge-how (Stanley and Williamson, The Journal of Philosophy 98(8):411–444, 2001; Hetherington, Epistemology futures, 2006). I contend that neither of these provides conclusive arguments against the distinction. Second, I discuss studies from neuroscience and experimental psychology that relate to this distinction. Having examined these studies, I then defend a third view that explains certain relevant data from these studies by positing the (...) double dissociation of knowledge-that and knowledge-how and that is also able to do explanatory work elsewhere.
