Wittgenstein and the Possibility of Inexplicably Losing Certainties

Though Wittgenstein's On Certainty has been influential in analytic epistemology, its interpretation has been enormously controversial. It is true that exegesis has been mainly concerned with the proper characterization of Wittgenstein's very notion of certainty'; however, some important questions remain unanswered regarding this notion. On the one hand, I am above all referring to the study of the possibilities we have of retaining a certainty when it has seemingly been placed into question and, on the other hand, of regaining a certainty once it has been lost. In this paper, I attempt to provide a detailed answer to both questions. In so doing, some important features of the picture of ourselves which emerges from Wittgenstein's On Certainty are also revealed.
