Abstract EN:

The occurence of psychosis causes one to rethink the subject concept, ranging in definition from the writing of Descartes to the phenomenology of Husserl and Heidegger. Binswanger's works on pathological cases shows the original intersubjective and intercorporal nature of all "ipseity". In 1922, Binswanger begins by refering to Husserl but later primarily focuses on the work of Heidegger, notably "Being and Time" ("Sein und Zeit"). He finally comes back to Husserl in his late texts. Heidegger's idea allow a transition from the transcendental subject to the "being-in-the-world" of psychotics. However, unlike Heidegger, Binswanger insists on intersubjectivity, "we-ness" ("Wirheit") and opposes love to anxiety. His return to Husserl questions the concept of the intentionality of the transcendental subject, establishes a distinction between empirical "ego", transcendental "ego" and pure "ego", gives a new light to the concept of the "alter ego". A new phenomenology of intimacy ("Heimat") becomes possible, clarified by a special reference to the concept of "in-between" as defined by Bin Kimura.
