Certeza animal: ¿Un tercer Wittgenstein?

Abstract

In this paper some of the latest interpretations of Ludwig Wittgenstein's On Certainty are analysed in order to distinguish to what extent it is possible to talk about a 'third' Wittgenstein. The topics discussed are: the novelty and importance attributed to On Certainty; the subversion of the traditional perspective about basic beliefs; and the 'new' anti-scepticism which exceeds Moore's common sense as an answer to radical scepticism. Furthermore, this discussion tries to offer some support in differentiating these keys that, like others of Wittgenstein, could have consequences in different fields of knowledge.
