Knowledge-how, true indexical belief, and action

Abstract

Intellectualism is the doctrine that knowing how to do something consists in knowing that something is the case. Drawing on contemporary linguistic theories of indirect interrogatives, Jason Stanley and Timothy Williamson have recently revived intellectualism, proposing to interpret a sentence of the form ‘DP know how to VP’ as ascribing to DP knowledge of a certain way w of VPing that they could VP in w. In order to preserve knowledge-how’s connection to action and thus avoid an overgeneration problem, they add that this knowledge must be had under a “practical” mode of presentation of w. I argue that there can be non-knowledgeable true beliefs under a practical mode of presentation and that some such beliefs would nevertheless be sufficient to establish knowledge-how’s characteristic connection to action, and thus count as knowledge-how. If so, Stanley and Williamson’s account is faced with a serious undergeneration problem. Moreover, the structural features on which the argument relies make it likely to present a quite general challenge for intellectualist strategies.
