Abstract

In his final notebook, published posthumously as On Certainty , Wittgenstein offers a sustained and, at least apparently, fragmentary treatment of skeptical issues. Given the ambiguity and obscurity of some of its remarks, in the recent literature on the subject we can find a number of competing interpretations of OC, particularly of the elusive concept of ‘hinges’, central to Wittgenstein’s last work. In this paper, I will discuss the dominant interpretations of OC in order to show how they fail to represent plausible renderings of his anti-skeptical thought. Finally, I will argue that the analogy between ‘hinges’ and ‘rules of grammar’, correctly understood and developed, can represent a plausible interpretation of Wittgenstein’s thought and, more importantly, a viable anti-skeptical strategy
