[Hatred and change of love into hatred from the psychiatric nosological aspect (author's transl)].

Pathological hatred affects belong to the paranoic reactions, paranoic developments and paranoid psychoses. The normal hatred affect helps as a means to the end of removing the object of hatred. The passion of hatred is an affect swinging between a feeling of triumph and a feeling of impotence and the cardinal symptom of a paranoic neurotic development. Hatred becomes monomania when the affect degenerates maniacally (e. g. queruousness) or perversely (e. g. misogyny). In catathymic mania, hatred is projected on to the "pursuer". The metamorphosis of love into hatred is historically and dynamically behind all normal and pathological manifestations of hatred.
