Reductionists about knowledge-wh hold that "s knows-wh" (e.g. "John knows who stole his car") is reducible to "there is a proposition p such that s knows that p, and p answers the indirect question of the wh-clause." Anti-reductionists hold that "s knows-wh" is reducible to "s knows that p, as the true answer to the indirect question of the wh-clause." I argue that both of these positions are defective. I then offer a new analysis of knowledge-wh as a special kind (...) of de re knowledge. (shrink)

_Identity and Discrimination_, originally published in 1990 and the first book by respected philosopher Timothy Williamson, is now reissued and updated with the inclusion of significant new material. Williamson here proposes an original and rigorous theory linking identity, a relation central to metaphysics, and indiscriminability, a relation central to epistemology.__ Updated and reissued edition of Williamson’s first publication, with the inclusion of significant new material Argues for an original cognitive account of the relation between identity and discrimination that has been (...) influential in the philosophy of perception Pioneers the use of epistemic logic to solve puzzles about indiscriminability Develops the application of techniques from mathematical logic to understand issues about identity over time and across possible worlds.

A significant argument for the claim that knowing-wh is knowing-that, implicit in much of the literature, including Stanley and Williamson (2001), is spelt out and challenged. The argument includes the assumption that a subject's state of knowing-wh is constituted by their involvement in a relation with an answer to a question. And it involves the assumption that answers to questions are propositions or facts. One of Lawrence Powers' counterexamples to the conjunction of these two assumptions is developed, responses to it (...) are rebutted, and the possibility of rejecting the second rather than the first of these assumptions is explored briefly.

The purpose of this paper is to raise some questions about the idea, which was first made prominent by Gilbert Ryle, and has remained associated with him ever since, that there are at least two types of knowledge (or to put it in a slightly different way, two types of states ascribed by knowledge ascriptions) identified, on the one hand, as the knowledge (or state) which is expressed in the ‘knowing that’ construction (sometimes called, for fairly obvious reasons, ‘propositional’ or (...) ‘factual’ knowledge) and, on the other, as the knowledge (or state) which is ascribed in the ‘knowing how’ construction (sometimes called ‘practical’ knowledge). This idea, which might be said to be Ryle's most lasting philosophical legacy, has, in some vague form, remained part of conventional wisdom in philosophy since he put it forward. My purpose here is fairly accurately described as ‘raising questions’, since both the criticisms of the received view (as I interpret it), and the positive alternative suggestions to be advanced, are, to some extent, tentative and exploratory. The aim is to assemble a broad range of evidence for the conclusion that we need to replace the standard account, to query especially what Ryle suggested as evidence for it, and to explore what seems to me to be the indicated replacement for it.

Intellectualism about knowledge-how is the view that practical knowledge is a species of propositional knowledge. I argue that this view is undermined by a difference in properties between knowledge-how and both knowledge-that and knowledge-wh. More specifically, I argue that both knowledge-that and knowledge-wh are easily transmitted via testimony while knowledge-how is not easily transmitted by testimony. This points to a crucial difference in states of knowledge. I also consider Jason Stanley's attempt to subsume knowledge-how under an account of de se (...) knowledge. I argue that there are crucial differences between de se knowledge and knowledge-how. Thus, this paper advances both the discussion of intellectualism and the literature on the nature of de se knowledge. (shrink)

Do you know who you are? If the question seems unclear, it might owe to the notion of ‘knowing-wh’ (knowing-who, knowing-what, knowing-when, etc.). Such knowledge contrasts with ‘knowing-that’, the more familiar topic of epistemologists. But these days, knowing-wh is receiving more attention than ever, and here we will survey three current debates on the nature of knowing-wh. These debates concern, respectively, (1) whether all knowing-wh is reducible to knowing-that (‘generalized intellectualism’), (2) whether all knowing-wh is relativized to a contrast proposition (...) (‘contrastivism about knowing-wh’), and (3) whether the context-sensitivity of knowing-wh is a semantic or purely pragmatic phenomenon (‘contextualism vs. invariantism about knowing-wh’). (shrink)

Various authors have attempted to understand knowledge-wh—or knowledge ascriptions that include an interrogative complement. I present and explain some of the analyses offered so far and argue that each view faces some problems. I then present and explain a newanalysis of knowledge-wh that avoids these problems and that offers several other advantages. Finally I raise some problems for invariantism about knowledge-wh and I argue thatcontextualism about knowledge-wh fits nicely with a very natural understanding of the nature of questions.

The Intellectualist thesis that know-how is a kind of propositional knowledge faces a simple problem: For any proposition p, it seems that one could know p without knowing how to do the activity in question. For example, it seems that one could know that w is a way to swim even if one didn't know how to swim oneself. In this paper I argue that this “sufficiency problem” cannot be adequately addressed by appealing to practical modes of presentation.

In recent years, a debate concerning the nature of knowing-how has emerged between intellectualists who claim that knowledge-how is reducible to knowledge-that and anti-intellectualists who claim that knowledge-how comprises a unique and irreducible knowledge category. The arguments between these two camps have clustered largely around two issues: intellectualists object to Gilbert Ryle's assertion that knowing-how is a kind of ability, and anti-intellectualists take issue with Jason Stanley and Timothy Williamson's positive, intellectualist account of knowing-how. Like most anti-intellectualists, in this paper (...) I will raise objections to Stanley and Williamson's account of knowing-how and also defend the claim that ability is necessary for knowing-how attributions. Unlike most discussions of knowing-how, however, I will return to more Rylean considerations in order to illustrate that any intellectualist account of knowing-how, not simply Stanley and Williamson's preferred variety, will fail because it will be unable to account for fundamental differences in the knowledge required to instantiate an ability and the knowledge involved in propositional thought. (shrink)

Reductive intellectualists hold that knowledge-how is a kind of knowledge-that. For this thesis to hold water, it is obviously important that knowledge-how and knowledge-that have the same epistemic properties. In particular, knowledge-how ought to be compatible with epistemic luck to the same extent as knowledge-that. It is argued, contra reductive intellectualism, that knowledge-how is compatible with a species of epistemic luck which is not compatible with knowledge-that, and thus it is claimed that knowledge-how and knowledge-that come apart.

Chapter 1: Ryle on Knowing How Chapter 2: Knowledge-wh Chapter 3: PRO and the Representation of First-Person Thought Chapter 4: Ways of Thinking Chapter 5: Knowledge How Chapter 6: Ascribing Knowledge How Chapter 7: The Cognitive Science of Practical Knowledge Chapter 8: Knowledge Justified Preface A fact, as I shall use the term, is a true proposition. A proposition is the sort of thing that is capable of being believed or asserted. A proposition is also something that is characteristically the (...) kind of thing that is true or false; that snow is white is a true proposition, that Barack Obama is President of the United States as I am writing these words is another. Facts in this sense are not only among the things we believe and assert; they are also the kinds of things we know. The thesis of this book is that knowing how to do something is the same as knowing a fact. It follows that learning how to do something is learning a fact. For example, when you learned how to swim, what happened is that you learned some facts about swimming. Knowledge of these facts is what gave you knowledge of how to swim. Something similar occurred with every other activity that you now know how to do, such as riding a bicycle or cooking a meal. You know how to perform activities solely in virtue of your knowledge of facts about those activities. (shrink)

This is a new release of the original 1949 edition.

Many philosophers believe that there is a fundamental distinction between knowing that something is the case and knowing how to do something. According to Gilbert Ryle, to whom the insight is credited, knowledge-how is an ability, which is in turn a complex of dispositions. Knowledge-that, on the other hand, is not an ability, or anything similar. Rather, knowledge-that is a relation between a thinker and a true proposition.

In this paper, I argue that there is a notion of 'counterfactual success' which stands to knowledge how as true belief stands to propositional knowledge. (I attempt to avoid the question of whether knowledge how is a type of propositional knowledge.).

Know -wh ascriptions are ubiquitous in many languages. One standard analysis of know -wh is this: someone knows-wh just in case she knows that p, where p is an answer to the question included in the wh-clause. Additional conditions have also been proposed, but virtually all analyses assume that propositional knowledge of an answer is at least a necessary condition for knowledge-wh. This paper challenges this assumption, by arguing that there are cases where we have knowledge-wh without knowledge- that of (...) an answer, for example in the cases familiar from arguments for the Extended Mind hypothesis.
