Existential analysis is not yet identified with a particular therapeutic approach. By beginning with a phenomenological foundation one can rederive the structure of existential analysis, and by so doing one discovers a technique that is particularly close to the theory of existential analysis. From phenomenology one learns to enter the present being-in-the-world of the patient without overlooking any of the qualities of that world. By centering in the present world one discovers the critical and the role of the patient's choosing. By this the patient feels understood and not interpreted, and discovers that he changes as the horizon of his present experiences expands. Starting from a phenomenological foundation one rediscovers existential analsysis and discovers that this analysis is a significant departure from classical therapies in several respects.
