Using Jaspers' methodically critical attitude (methodenkritische Einstellung) we distinguish three aspects of his understanding of psychotherapy: (1) psychotherapy gains scientific quality via methodical strictness (and is therefore independent of a therapist's weltanschauung); (2) psychotherapy is a (more or less) 'hermeneutical' method of self-enlightenment, offering limited statements with respect to one's life conduct; and (3) psychotherapy oversteps its epistemological limits if gaining the status of a weltanschauung, instead of leading to (existential) philosophizing in the face of transcendence. Following Jaspers we try to answer the question: What are the limits of psychotherapeutic methods with respect to questions of life conduct? The most important limit is the unbreakable linkage between the style of one's life conduct and the (personally) experienceable (superpersonal) sense of life, which cannot be disrupted with the means of any justifiable belief or falsifiable knowledge. Quite to the contrary, this existential linkage is the starting point of many psychotherapeutic interventions.

Friedrich Hölderlin (1770-1843) is one of the most important German poets. Actual research into his life and work has shown new aspects in his thinking concerning questions about subjectivity, sense of life and psychosis. We follow these lines using a hermeneutical method. In his late poems the experience of schizophrenic alienation appears metaphorically speaking like an ebbing of a former plenitude of meanings or as if he were decentered from his own life. Hölderlin names it an "uninvolved" view onto the ordinary life. Hölderlin invites and enables us via his offer for an innerperspective understanding of the schizophrenic experience of alienation to deal fairly and respectfully with schizophrenic patients as if we were "alienists" (E. Straus).
