In this paper a two-dimensional theory is developed for the understand
ing of neuroses and personality disorders which are conceptualized as
spezific problems in the field of personal identity. The first dimensi
on serves for the description of the symptomatology between the two po
les anxiety and depression. The second dimension is right-angled to th
e first. It differentiates according to the maturity of the personal i
dentity between the two extremes mature neurotic personality organizat
ion on the one hand and severe personality disorder on the other. Any
specific neurosis or personality disorder can be allocated to the two
axes of this model.
