Timothy Williamson devotes significant effort in his The Philosophy of Philosophy to arguing against skepticism about judgment. One might think that the recent “experimental philosophy” challenge to the philosophical practice of appealing to intuitions as evidence is a possible target of those arguments. However, this is not so. The structure of that challenge is radically dissimilar from that of traditional skeptical arguments, and the aims of the challenge are entirely congruent with the spirit of methodological improvement that Williamson himself exemplifies in the Afterword of his book.

Using empirical evidence to attack intuitions can be epistemically dangerous, because various of the complaints that one might raise against them (e.g., that they are fallible; that we possess no non-circular defense of their reliability) can be raised just as easily against perception itself. But the opponents of intuition wish to challenge intuitions without at the same time challenging the rest of our epistemic apparatus. How might this be done? Let us use the term “hopefulness” to refer to the extent to which we possess a good capacity for the detection and correction of the errors of any fallible source of evidence. I argue that we should not trust putative sources of evidence that are substantially lacking in hopefulness (even if they are basically reliable), and that we are indeed already operating under such a norm in our ordinary and scientific practices. I argue further that the philosophical practice of the appeal to intuitions is, in these terms, badly hopeless...

The liar paradox is widely conceived as a problem for logic and semantics. On the basis of empirical studies presented here, we suggest that there is an underappreciated psychological dimension to the liar paradox and related problems, conceived as a problem for human thinkers. Specific findings suggest that how one interprets the liar sentence and similar paradoxes can vary in relation to one’s capacity for logical and reflective thought, acceptance of certain logical principles, and degree of philosophical training, but also as a function of factors such as religious belief, gender, and whether the problem is treated as theoretical or practical. Though preliminary, these findings suggest that one reason the liar paradox resists a final resolution is that it engages both aspects described by so-called dual process accounts of human cognition.

In order for Herman Cappelen to argue in his Philosophy Without Intuitions that philosophers have been on the whole mistaken in thinking that we actually use intuitions much at all in our first-order philosophizing, he must attempt the task of characterizing what something must be, in order to be an intuition.My discussion here is focused on the latter half of the book concerning the “argument from philosophical practice. I am in wholehearted agreement with the first half’s thesis that the usage of the term “intuition” is highly motley and of no methodological use. I truly sympathize with the frustration he evidently feels at wrangling with that task, because I’ve felt the same in my own project critiquing what I do take to be a fairly common practice in contemporary philosophy that we often gesture at when we speak of intuitions. For the literature on intuitions can be a total mess on even the most basic questions about what intuitions are: beliefs, or sui generis seemings? Special in ..

It has been standard philosophical practice in analytic philosophy to employ intuitions generated in response to thought-experiments as evidence in the evaluation of philosophical claims. In part as a response to this practice, an exciting new movement—experimental philosophy—has recently emerged. This movement is unified behind both a common methodology and a common aim: the application of methods of experimental psychology to the study of the nature of intuitions. In this paper, we will introduce two different views concerning the relationship that holds between experimental philosophy and the future of standard philosophical practice (what we call, the proper foundation view and the restrictionist view), discuss some of the more interesting and important results obtained by proponents of both views, and examine the pressure these results put on analytic philosophers to reform standard philosophical practice. We will also defend experimental philosophy from some recent objections, suggest future directions for work in experimental philosophy, and suggest what future lines of epistemological response might be available to those wishing to defend analytic epistemology from the challenges posed by experimental philosophy.
