Abstract

"Person� is a very ambiguous word (as most of our words when isolated). The outstanding vagueness of the terms used in philosophical discourse, like "action� or "mind�, is an essential characteristic of language that provides the set upon which philosophy relies. Indeed, inquiries into certainty, objectivity and many other important metaphysical problems would never arise if this indeterminacy were not present in language. The history of philosophy as such can be considered as a quest for meaningful statements on which we can ground our judgment. This search for certainty has an ethical dimension, since it discloses what we have in common and what we cannot share. An important feature of this ethical dimension is that the investigation of "certainty� is, at the same time, a struggle against arbitrariness. However, we must be careful while engaging into this exploration, by refusing to analyze or equate certainty with goodness or correctness. The danger of this attractive analysis is evident in our religious and political history. I believe that Wittgenstein can help us in elucidating some of these difficult issues. The problem of the identity of persons, or what constitutes a human being, pervades through philosophical texts. The general strategy of this paper is to link the issue of certainty, as explained by Wittgenstein, with the concept of person
