 Finally, some have questioned whether Semantics for knowledge-wh applies to ascriptions embedding infinitival complements, like knowledge-how ascriptions. Roberts (2009) argues that, as opposed to other wh complements, the meaning of “how” denotes a property rather than a proposition when embedded in infinitival clauses. Santorio (2016) defends a Gibbardian semantics for knowledge ascriptions embedding infinitive interrogatives, on which these ascriptions ascribe maximal performance plans compatible with an agent’s plans (for more objections to Semantics for knowledge-wh, see also Sgaravatti &amp; Zardini 2008 and George 2013).
