In “Knowing How”, Jason Stanley and Timothy Williamson (2001) propose an intellectualist account of knowledge-how, according to which all knowledge-how is a type of propositional knowledge about ways to act. In this article, I examine this intellectualist account by applying it to the epistemology of language. I argue that (a) Stanley and Williamson mischaracterize the concept of knowledge-how in the epistemology of language, and (b) intellectualism about knowledge of language fails in its explanatory task. One lesson that can be drawn from this case study is that Stanley and Williamson's intellectualism is limited in its explanatory scope and power insofar as it cannot explain the knowledge of language, which is usually conceived as knowledge-how and as non-propositional in character. Their intellectualist claim that all knowledge-how is knowledge-that should be withdrawn.

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.

Though he’s perhaps best known for his work on vagueness, Timothy Williamson also produced a series of outstanding papers in epistemology in the late 1980's and the 1990's. Knowledge and its Limits brings this work together. The result is, in my opinion, the best book in epistemology to come out since 1975.

Gilbert Harman has written: “Williamson‟s Knowledge and its Limits is the most important philosophical discussion of knowledge in many years. It sets the agenda for epistemology for the next decade and beyond” (Harman 2002, p. 417). Timothy Williamson‟s ground-breaking proposal is that knowing is “merely a state of mind”. In other words, for every proposition p “there is a state of mind being in which is necessary and sufficient for knowing p” (Williamson 2000, p. 21). When first advanced, Williamson‟s view ran contrary to the general trend. The “standard view” (ibidem) was that “believing is merely a state of mind, but..

In his Knowledge and its Limits (2000) Timothy Williamson argues that knowledge can be causally efficacious and as such figure in psychological explanation. His argument for this claim figures as a response to a key objection to his overall thesis that knowing is a mental state. In this paper I argue that although Williamson succeeds in establishing that knowledge in some cases is essential to the power of certain causal explanations of actions, he fails to do this in a way that establishes knowledge itself as a causal factor. The argument thus fails to support his overall claim that knowledge should be conceived as a state of mind.

Williamson (2000) [Knowledge and its Limits, Oxford: Oxford University Press] argues that attempts to substitute narrow mental states or narrow/environmental composites for broad and factive mental states will result in poorer explanations of behavior. I resist Williamson.
