Viktor E. Frankls logotherapy is essentially a psychotherapeutic system including a distinct philosophical
anthropology and Weltanschauung. "Meaning of life" is the key concept. This treatise intends to deal with the
entire Frankl system, it discusses therefore the following parts: (I.) its history, i.e the genesis of logotherapy and its
development, (II.) its philosophy, (III.) the clinical part: theory and inceptively its practical approach, and (IV) the
theological aspects. The latter part tries to work out Frankls religious concept. Because of it being dominated by the
superego notion (psychologically) and the metaphysical notion of supra meaning (theologically) it is of doubtful
use for the purpose of psychotherapy. Hence the attempt is being made in this study to replace it by a different
religious concept. Since this has to be in principle universally relevant- also in the mind of Frankl - I chose a
cosmological God concept and a highly individualized religion concept (God-man-relationship). The general intent
of this treatise being internally critical, it also calls for an integration of the missing psychodynamic dimension
within the clinical parts of logotherapy. The positive aspects of the system are being honored, especially in regard
to its offering vistas for meaning in life and calling attention to existential freedom of attitudes and personal
choices; also the individualistic and humanistic therapeutic approach is being honoured. The strengths and
weaknesses of the person of Frankl are being correlated with the strength and weaknesses of the system of
logotherapy.
