It is often argued that the general propriety of challenging an assertion with ‘How do you know?’ counts as evidence for the Knowledge Norm of Assertion . Part of the argument is that this challenge seems to directly challenge whether a speaker knows what she asserts. In this article I argue for a re‐interpretation of the data, the upshot of which is that we need not interpret ‘How do you know?’ as directly challenging a speaker's knowledge; instead, it's better understood (...) as challenging a speaker's reasons. Consequently, I argue that reasons‐based norms can equally well explain this data. (shrink)

Many believe that George Berkeley and, subsequently, David Hume offer devastating arguments against John Locke's theory of abstract ideas. It is the purpose of this paper to clarify the attacks given a close reading of Locke. It will be shown that many of the arguments of Berkeley and Hume are of a straw man nature and, moreover, that some of their conclusions are actually in accord with Locke.

This paper addresses an argument offered by John Hawthorne against the propriety of an agent’s using propositions she does not know as premises in practical reasoning. I will argue that there are a number of potential structural confounds in Hawthorne’s use of his main example, a case of practical reasoning about a lottery. By drawing these confounds out more explicitly, we can get a better sense of how to make appropriate use of such examples in theorizing about norms, knowledge, and (...) practical reasoning. I will conclude by suggesting a prescription for properly using lottery propositions to do the sort of work that Hawthorne wants from them. (shrink)
