Die Entfaltung Der Psychoanalyse: Das Wirken Sigmund Freuds in die Gegenwart. (The Development of Psycho-analysis. Freud's Impact on the Present Time.) Edited by Alexander Mitscherlich. Psyche Supplement. (Stuttgart: Ernest Klett, 1957. Pp. 276.)

This is a collection of fifteen articles, several of which have appeared elsewhere. Among the contributors are Alexander, Hartmann, Spitz, Lebovici, Erikson, Jeanne Lampl-De Groot, Winnicott, Krapf, Zulliger. There is an essay by Kate Victorius on Freud's identification with Moses. Scheunert gives an interesting survey of recent trends in psycho-analytical ego-psychology. Schottlander discusses the rôle of pictorial images in religion, dream, and psychosis as well as in the mechanism of projection. Mitscherlich, in a thoughtful essay entitled 'Aggression and Adaptation', discusses the problem of collective aggression and its control by society. He poses the question how aggression interferes with adjustment to the social code. He differentiates aggression from activity, i.e. the destructive attack from aimdirected and constructive function of the motor apparatus. He regards the question of the origin of aggression in the death instinct as insoluble and rejects a unitary derivation of aggression in the broadest sense. Ruffler discusses the technique of in-patient psycho-analysis as practised in Mitscherlich's department at Heidelberg. His observations are of considerable clinical interest.

This volume is a worthy contribution to the Freud centenary. It informs the German reader of important recent developments in psycho-analysis.
