In Gestalt Therapy all attempts at diagnostic categorization and nosology have always been treated with caution. This paper gives a contribution to the debate on this subject. The main question is: how can diagnosis, and the value given to lived and momentary experience, be combined? The first part presents a Gestalt perspective on psychopathology as the suffering of "the between", that is the contact boundary. The second part distinguishes extrinsic (or map) and intrinsic (or aesthetic) diagnosis. Some hypotheses are presented to illustrate how both map and aesthetic diagnosis can be dealt with in therapeutic relationships, preventing the crystallization into fixed gestalten of people and their experiences. (English version: British Gestalt Journal, 18, 2, 5-20).
