Stanley and Williamson (The Journal of Philosophy 98(8), 411–444 2001 ) reject the fundamental distinction between what Ryle once called ‘knowing-how’ and ‘knowing-that’. They claim that knowledge-how is just a species of knowledge-that, i.e. propositional knowledge, and try to establish their claim relying on the standard semantic analysis of ‘knowing-how’ sentences. We will undermine their strategy by arguing that ‘knowing-how’ phrases are under-determined such that there is not only one semantic analysis and by critically discussing and refuting the positive account of knowing-how they offer. Furthermore, we argue for an extension of the classical ‘knowing-how’/‘knowing-that’-dichotomy by presenting a new threefold framework: Using some core-examples of the recent debate, we will show that we can analyze knowledge situations that are not captured by the Rylean dichotomy and argue that, therefore, the latter has to be displaced by a more fine-grained theory of knowledge-formats. We will distinguish three different formats of knowledge we can have of our actions, namely (1) propositional, (2) practical, and (3) image-like formats of knowledge. Furthermore, we will briefly analyze the underlying representations of each of these knowledge-formats.

It has often been thought that our knowledge of ourselves is _different_ from, perhaps in some sense _better_ than, our knowledge of things other than ourselves. Indeed, there is a thriving research area in epistemology dedicated to seeking an account of self-knowledge that would articulate and explain its difference from, and superiority over, other knowledge. Such an account would thus illuminate the descriptive and normative difference between self-knowledge and other knowledge.¹ At the same time, self- knowledge has also encountered its share of skeptics – philosophers who refuse to accord it any descriptive, let alone normative, distinction. In this paper, we argue that there is at least one _species_ of self-knowledge that is different from, and better than, other knowledge. It is a specific kind of knowledge of one’s concurrent phenomenal experiences. Call knowledge of one’s own phenomenal experiences _phenomenal knowledge_. Our claim is that some (though not all) phenomenal knowledge is different from, and better than, non-phenomenal knowledge. In other.

In this paper, we present a number of problems for intellectualism about knowledge-how, and in particular for the version of the view developed by Stanley & Williamson 2001. Their argument draws on the alleged uniformity of 'know how'-and 'know wh'-ascriptions. We offer a series of considerations to the effect that this assimilation is problematic. Firstly, in contrast to 'know wh'-ascriptions, 'know how'-ascriptions with known negative answers are false. Secondly, knowledge-how obeys closure principles whose counterparts fail for knowledge-wh and knowledge-that. Thirdly, as opposed to knowledge-wh and knowledge-that, knowledge-how is inferentially isolated from further knowledge-that. We close by providing some evidence against the further reduction of knowledge-wh to knowledge-that, which is presupposed by the intellectualist theory under discussion.

A central argument against Ryle’s (The concept of mind, University of Chicago Press, Chicago, 1949 ) distinction between propositional and non propositional knowledge has relied on linguistic evidence. Stanley and Williamson (J Philos 98:411–444, 2001 ) have claimed that knowing-how ascriptions do not differ in any relevant syntactic or semantic respect from ascriptions of propositional knowledge, concluding thereby that knowing-how ascriptions attribute propositional knowledge, or a kind thereof. In this paper I examine the cross-linguistic basis of this argument. I focus on the linguistic analysis of practical knowledge ascriptions in Modern Greek, although the issues raised are not restricted to one language. It is relatively straightforward to show that none of the three types of practical knowledge ascriptions in Modern Greek is an embedded question configuration, and hence Stanley and Williamson original claim is confined to certain languages only. This is not the end of the matter, however, since Stanley (Nous 45:207–238, 2011 ) argues that the equivalents of ‘knowing-how’ ascriptions in certain languages should be semantically analyzed as embedded questions despite their syntactic form. I argue that this fallback position faces a host of empirical and theoretical problems, in view of which it cannot bear the weight Stanley puts on it, supporting a conclusion about the kind of knowledge thereby attributed.

This paper is roughly in two parts. The first deals with whether know-how is constituted by propositional knowledge, as discussed primarily by Gilbert Ryle (1949) The concept of mind. London: Hutchinson, Jason Stanley and Timothy Williamson (2001). Knowing how. Journal of Philosophy, 98, pp. 411–444 as well as Stephen Hetherington (2006). How to know that knowledge-that is knowledge-how. In S. Hetherington (Ed.) Epistemology futures. Oxford: Oxford University Press. The conclusion of this first part is that know-how sometimes does and sometimes does not consist in propositional knowledge. The second part defends an analysis of know-how inspired by Katherine Hawley’ (2003). Success and knowledge-how. American Philosophical Quarterly, 40, pp. 19–31, insightful proposal that know-how requires counterfactual success. I conclude by showing how this analysis helps to explain why know-how sometimes does and sometimes does not consist of propositional knowledge.

Since the most promising path to a solution to the problem of skepticism regarding perceptual knowledge seems to rest on a sharp distinction between perceiving and inferring, I begin by clarifying and defending that distinction. Next, I discuss the chief obstacle to success by this path, the difficulty in making the required distinction between merely logical possibilities that one is mistaken and the real (Austin) or relevant (Dretske) possibilities which would exclude knowledge. I argue that this distinction cannot be drawn in the ways Austin and Dretske suggest without begging the questions at issue. Finally, I sketch and defend a more radical way of identifying relevant possibilities that is inspired by Austin's controversial suggestion of a parallel between saying I know and saying I promise: a claim of knowledge of some particular matter is relative to a context in which questions about the matter have been raised.

The paper argues that, although a distinction between a priori and a posteriori knowledge (or justification) can be drawn, it is a superficial one, of little theoretical significance. The point is not that the distinction has borderline cases, for virtually all useful distinctions have such cases. Rather, it is argued by means of an example, the differences even between a clear case of a priori knowledge and a clear case of a posteriori knowledge may be superficial ones. In both cases, experience plays a role that is more than purely enabling but less than strictly evidential. It is also argued that the cases at issue are not special, but typical of a wide range of others, including knowledge of axioms of set theory and of elementary logical truths. Attempts by Quine and others to make all knowledge a posteriori (‘empirical’) are repudiated. The paper ends with a call for a new framework to be developed for analysing the epistemology of cognitive uses of the imagination.

I shall be mainly concerned with the question ‘What is personal propositional knowledge?’. This question is obviously quite narrowly focused, in three respects. In the first place, there is impersonal as well as personal knowledge. Second, a distinction is often drawn between propositional knowledge and practical knowledge. And third, as well as asking what knowledge is, it is also possible to ask whether and how knowledge of various kinds can be acquired: causal knowledge, a priori knowledge, moral knowledge, and so on. I shall dwell briefly on each of these three points. First, there is the distinction between personal and impersonal knowledge – in other words, between the psychological concept of knowledge and the social one.1 We use the concept of knowledge to describe the cognitive condition of individuals; but we also use it to describe the progress of scientific and historical research. So for example we can speak or enquire about the state of knowledge in a particular field of biology or history. And if we do so, we are evidently not concerned with what anyone in particular knows about, say, the genetics of fruit flies or the career of Charlemagne, but rather with what the scientific or academic community knows. Needless to say, there is a close connection between personal and impersonal knowledge. But ‘It is known that p’ does not simply mean ‘Someone or other..

Ernest Sosa draws a distinction between animal knowledge and reflective knowledge, and this distinction forms the centerpiece of his new book, A Virtue Epistemology . This paper argues that the distinction cannot do the work which Sosa assigns to it.

Stanley and Williamson reject Ryle's knowing-how/knowing-that distinction charging that it obstructs our understanding of human action. Incorrectly interpreting the distinction to imply that knowledge-how is non-propositional, they object that Ryle's argument for it is unsound and linguistic theory contradicts it. I show that they (and their interlocutors) misconstrue the distinction and Ryle's argument. Consequently, their objections fail. On my reading, Ryle's distinction pertains to, not knowledge, but an explanatory gap between explicit and implicit content, and his argument for it is sound. I defend the distinction's necessity in explaining human action and show that it propels a fruitful explanatory program.
