Logotherapy and existential analysis are like two sides of the same coin and therefore belong together. Both terms are sometimes used synonymously. Existential analysis deals with the ideal of man and diagnosis, whereas Logotherapy deals with the psychotherapeutic basics and the meaning-centered practice. In addition to body and soul, existential analysis also assumes a spiritual dimension, which makes man specifically human. In doing so, it opposes the modern reductionism that we encounter more and more in psychology, medicine and the neurosciences; because, in contrast to this, the aim of existential analysis is to make people (again) aware of their “responsibility”, so that they can become the Creative shaper of their life again, instead of letting them stay dependent. The extension by the third, the mental, dimension enables an active and responsible lifestyle.
