Abstract
In this paper, I argue that the views of Robert Kane on the one hand and John Fischer and Mark Ravizza on the other both lead to the following conclusion: we should have very low confidence in our ability to judge that someone is acting freely or in a way for which they can be held responsible. This in turn means, I claim, that these views, in practice, collapse into a sort of hard incompatibilist position, or the position of a free will denier. That would at least be an unintended consequence, and it might be regarded as a virtual reductio. Versions of the objection could likely be made against a number of other accounts of free will, but I will limit my focus to Kane and Fischer. Along the way, by way of response to some possible objections to my argument, I make some comments about epistemic closure principles
