What role does ‘ordinary language philosophy’ play in the defense of common sense beliefs? J.L. Austin and Ludwig Wittgenstein each give central place to ordinary language in their responses to skeptical challenges to common sense beliefs. But Austin and Wittgenstein do not always respond to such challenges in the same way, and their working methods are different. In this paper, I compare Austin’s and Wittgenstein’s metaphilosophical positions, and show that they share many metaphilosophical commitments. I then examine Austin and Wittgenstein’s (...) respective takes on the problem of other minds and the problem of our knowledge of the external world. Interestingly, we find Wittgenstein employing methods more frequently associated Austin and vice versa. Moreover, we find that a variety of defenses of common sense beliefs are compatible with ‘ordinary language philosophy.’. (shrink)

This paper clarifies Wittgenstein’s critique of Moore in _On Certainty,_ and argues that this critique is largely misunderstood, for two reasons. Firstly, Wittgenstein partly misrepresents Moore. Secondly, Wittgenstein is wrongly taken to be an internalist regarding justification for knowledge. Once we realize these two points, we can understand Wittgenstein’s critique properly as a grammatical argument in that Moore fails to see how the concepts of knowledge and certainty relate to those of justification and evidence. On this reading, we can also (...) understand that Moore and Wittgenstein were in more agreement than many people have thought, even though Moore was not able to exploit and express his philosophical insights properly.

This article examines Wittgenstein’s criticism of Moore’s use of “know”, as he developed it in On Certainty. Arguing against much of the literature, the author claims that, by Wittgenstein’s own lights, Moore was not talking nonsense. He does so by showing, first, that the standard reading is based on the idea that hinge propositions are non-epistemic, and second, that Wittgenstein’s alleged adoption of the non-epistemic view is not adequately supported by the textual evidence. The author argues that claims to the (...) contrary depend on an undue conflation, on the part of interpreters, of Wittgenstein’s treatment of psychological avowals in Philosophical Investigations and his discussion of hinge propositions in On Certainty. Moreover, a closer look at Wittgenstein’s objections to Moore shows that Wittgenstein himself repeatedly charged Moore with a similar confusion between the status of psychological statements and the status of his common-sense truisms.
