From Existential- humanism approach to Frankl`s Logotherapy

Without understanding the existentialist-humanist approach, one cannot know Frankel, the Analysis of Existence, and the Logotherapy. So, in this descriptive-analytic study conducted after studying various books and articles, firstly, we reviewed the three waves of psychology, namely psychoanalysis, behaviorism, and humanism. Secondly, the theory of "Abraham Maslow's self-actualization" and "Carl Rogers` person-centered approach" as two significant theories of humanism were discussed not only as a social movement but also as the third wave in psychology. Then, the concepts of Frankl's theory of "Analysis of Existence" and his model of treatment of "Logotherapy" were described in detail, as well as its strengths and weaknesses. Finally, a comparative overview of these three theories was presented in the conceptual and therapeutic dimensions. In conclusion, Maslow's theories of self-actualization and Karl Rogers` person-centered theory as well as the method of Frankl, everyone in a specific way, have attempted to give the power of spirituality, freedom, power of choice, and responsibility to the person who is captivated by unconscious conflicts or external stimuli to make a meaningful life.
