Abstract

In the broadest sense, Propositionalism is the view that knowing how to do something first requires our possessing appropriate propositional attitudes about an action. Non-propositionalism concerning knowing how, is the rejection of propositionalism. This distinction, and the rejection of propositionalism is typically traced back to Gilbert Ryle. In the 21st century, propositionalists have tried to turn the tables with a quick and decisive argument against non-propositionalism. According to the argument from pervasive inability, since (1) There are numerous cases in which someone knows how to do something while possessing a pervasive inability to perform the action she knows how to do, and (2) these cases can be unproblematically explained to be instances of knowing how by propositionalism, but (3) these cases cannot be explained to be instances of knowing how by non-propositionalism, therefore (4) non-propositionalism must be rejected in favor of propositionalism. In this paper, through a careful examination of proposed cases, I argue that premise two is not true, and by correcting propositionalists’ mischaracterization of non-propositionalism, I argue that premise three is also not true. As a result, the argument from pervasive inability fails to provide a decision between propositionalism and non-propositionalism concerning knowing how.
