[Jennifer Hornsby] The central claim is that the semantic knowledge exercised by people when they speak is practical knowledge. The relevant idea of practical knowledge is explicated, applied to the case of speaking, and connected with an idea of agents' knowledge. Some defence of the claim is provided. /// [Jason Stanley] The central claim is that Hornsby's argument that semantic knowledge is practical knowledge is based upon a false premise. I argue, contra Hornsby, that speakers do not voice their thoughts directly. Rather, our actions of voicing our thoughts are justified by decisions we make (albeit rapidly) about what words to use. Along the way, I raise doubts about other aspects of the thesis that semantic knowledge is practical knowledge.

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well.

In defending his interest-relative account of knowledge in Knowledge and Practical Interests (2005), Jason Stanley relies heavily on intuitions about several bank cases. We experimentally test the empirical claims that Stanley seems to make concerning our common-sense intuitions about these bank cases. Additionally, we test the empirical claims that Jonathan Schaffer seems to make in his critique of Stanley. We argue that our data impugn what both Stanley and Schaffer claim our intuitions about such cases are. To account for these results, one must develop a better conception of the connection between a subject's interests and her body of knowledge than those offered by Stanley and Schaffer.

The latest newcomer on the epistemology scene is Subject-Sensitive Invariantism (SSI), which is the view that even though the semantics of the verb “know” is invariant, the answer to the question of whether someone knows something is sensitive to factors about that person. Factors about the context of the purported knower are relevant to whether he knows some proposition p or not. In this paper I present Jason Stanley's version of SSI, a theory Stanley calls Interest-Relative Invariantism (IRI). The core epistemological claim of IRI is that knowledge is conceptually connected to practical interests. Stanley's defence of IRI is closely connected to practical reasoning, but unfortunately, I argue, IRI leads to bad practical reasoning. I furthermore show that Stanley's IRI cannot accommodate all of Stanley's five test cases for knowledge attribution, test cases that are supposed to (more or less) make or break theories of knowledge attribution. IRI also has some quite counterintuitive results and derives much of its appeal from one-sidedness of Stanley's examples. The net effect, I claim, is that IRI should be resisted.
