In this contribution we will offer a reading of Freud’s ambiguous therapeutic “advice” to “say more than one knows”. Starting from some preliminary reflections on the issue of confession and Lacan’s theoretical distinction between enunciation/enunciated, we will propose three successive ideas with regard to the notions of unconscious, truth and subjectivity. Firstly, a connection will be established between unconscious enunciation and Austin’s couple of performative/constative utterances. Secondly, we will offer a psychoanalytic notion of “truth” through a brief comparison with the phenomenological procedures of epoché and reduction. Third and finally, we will end with some reflections on the psychoanalytic couple of knowledge and truth.
