[Contact disorders as a problem of the civilized society].

Emotional chillness of human living together in modern civilized societies is provoking not only an increasing amount of neurotic diseases on the one hand and unsteadiness on the other, but also beyond that some distinct kinds of mental disorders. Psychodynamic sources of those disturbances are discussed, guided by case reports on paranoic reaction, cardiac neurosis, depressive reaction, delusion of being beloved, alcoholism after getting widowed, and paranoid hallucinatory Psychosis as a result of loneliness.
