 Pavese (2017) distinguishes between two kinds of gradability of knowledge-how ascriptions: one might know how to do something in part or entirely (quantitative gradability) or one might know how to do something better than somebody else (qualitative gradability). Crucially, these two kinds of gradability are also present more generally in other knowledge-wh (knowledge-when, who, why, where) ascriptions, which do seem to reduce to propositional knowledge. For instance, one might know in part who came to the party (Lahiri 1991, 2000; Roberts 2009) or know a better answer to that question than somebody else (see also Stanley 2011b: 31–5). If parts of an answer are propositions, then knowing an answer might still amount to knowledge of all of its parts. Knowing in part an answer would then amount to knowing at least one of the propositions that is part of that answer. Similarly, knowing a better answer amounts to knowing a proposition that better answers the relevant question. If this is true of other knowledge-wh ascriptions, it is certainly plausible that it is true for knowledge-how. One might know how to Φ in part by knowing only certain (propositional) parts of the answer to “how does one Φ?” and one might know a better answer to that question than someone else.
