Abstract

This paper aims at showing the fecundity of the notion of ipseity or self in the domain of psychopathology. The notions of subject or ego which have been used since Descartes to describe the being of man have led to thing it on the model of a substantial and unalterable being. Contemporary philosophy, especially with Heidegger, has on the contrary elaborated a quite other conception of man as an essentially temporal and relational being. What constitutes fundamentally the being of man is no the presence of an invariable nucleus of personality, but it is on the contrary the relations that he is able to establish with the world and the others which defines it in return. The notion of self defines therefore the reflexive character of the being of man.As Paul Ricoeur also shows, the identity of the human being is fundamentally a narrative identity, i.e. an identity that constitutes itself through the hazards of a history. What is deeply altered in the different forms of mental diseases is precisely this openness and receptivity that defines the self. What has therefore to be restores by means of therapy is the capacity of the human being to constitute himself as a self in time and to open itself to the unforeseeable character of what happens to him.
