CORREA, Cristia Rosineiri Gonçalves Lopes. Certainty and delusional beliefs. Mental [online]. 2008, vol.6, n.10, pp. x-xx. ISSN 1679-4427.

This article examines the approach to certainty and delusional beliefs in philosophy and psychoanalysis. It suggests that whereas Wittgenstein provides an understanding of psychopathological concepts such as delusional beliefs and its relationship to judgements of rationality, Lacan, in psychoanalysis seems to suggest that it is subjective certainty what marks out beliefs as delusional. In this sense, the present article proposes that Lacan’s account questions Wittgenstein’s suggestion that delusional beliefs would be constituted by a failure in rationality.

Keywords : Certainty; Delusional beliefs; Lacan; Rationality; Wittgenstein.
