FACTIVITY WITHOUT SAFETY

: I summarize Timothy Williamson's theory of knowledge, construct some counterexamples to it, and try to diagnose the problem in virtue of which those counterexamples arise. Then I consider possible responses. It turns out that only one of those responses is tenable, and that that response renders Williamson's theory a continuous piece of, rather than a radical paradigmatic break from, recent mainstream work in the theory of knowledge.
