Jason Stanley and Timothy Williamson's influential article "Knowing How" argues that knowledge-how is a species of knowledge-that. One objection to their view is that knowledge-how is significantly different than knowledge-that because Gettier cases afflict the latter but not the former. Stanley and Williamson argue that this objection fails. Their response, however, is not adequate. Moreover, I sketch a plausible argument that knowledge-how is not susceptible to Gettier cases. This suggests a significant distinction between knowledge-that and knowledge-how.
