ABSTRACT
Whereas states of morbid anxiety have been dealt with in detail in the literature of psycho-analysis, depressive states have hitherto received less attention. Nevertheless the affect of depression is as widely spread among all forms of neuroses and psychoses as is that of anxiety. The two affects are often present together or successively in one individual; so that a patient suffering from an anxiety-neurosis will be subject to states of mental depression, and a melancholic will complain of having anxiety.
