Was sagen „objektive“ Messverfahren über Sexualstraftäter?

A great deal of effort has been made to use so-called objective measurements in men convicted of child sexual abuse in recent years. The aim of using these procedures is to measure sexual preference for children more effectively while being less vulnerable for deception and to add information to subjective reports. In this paper it was investigated why research activities in this area have increased and what so-called “objective” measurements can reveal about sexual offenders. This article will discuss possible pros and cons of the use of such procedures for forensic court reports or in the context of therapy in a forensic setting.

Im „Fort-Da“ entwickelt sich das Selbst

Freud’s view of the infant as passive and undifferentiated, motivated primarily by the goal of tension reduction, who needs his objects only for the satisfaction of his oral needs, is not shared by many psychologists any more. In this essay I try with the help of other approaches of developmental psychology such as Bühler and Lichtenstein to create a connection to Gestalt theory. Gestalt psychology was before the Second World War the leading psychological theory even outside the borders of Germany and experiences today a silent comeback in psychoanalytical infant research and the theories of intersubjectivity. Central characteristics of development are the changes in the individual in the context of his environment: expansion, transformation and reorganization. Integration plays an important role, because development is not only a differentiation of parts, but at the same time an increasing connection of all these parts to each other. This is another axiom of Gestalt theory confirmed meanwhile by modern brain research.

Der Ideologiebegriff bei Marx und die heutige Kontroverse über Ideologie und Wissenschaft in den sozialistischen Ländern

Marx and Engels inherited and developed the 18th Century notion of ideology as distorted consciousness. Although they did not speak explicitly of a ‘proletarian ideology’, they did develop the elements which Lenin then elaborated. His failure to develop a theory of ideology has left this task to contemporary Marxists (e.g., Althusser) and Marxist-Leninists (e.g., Choruc), who often do this in the process of criticizing non-Marxist theories. A lively discussion took place in the 1960's in Poland (Schaff and Bauman) and in the Soviet Union (Jadov and Julina). One of the results has been to cast doubt on the systemic validity of the principle of party-mindedness (partijnost').

Brauchen wir das Konzept der „Spaltung“?

The author expresses his doubts about the interaction of splitting and other defence mechanisms as denial, primitive idealization, omnipotence, depreciation in the form as Kernberg proposed it for the psychodynamic explanation of the borderline personality structure. It is shown that to postulate splitting leads to contradictions and that denial, primitive idealization, omnipotence and depreciation cannot be considered as genuine defence mechanisms. It is argued that primitive idealization too is actually a reaction formation, or that the omnipotence of these personalities is due to a transitive identification with the idealized ego functions of their objects, and that the described clinical phenomena can be explained by the connection of projection with primitive idealization resp. isolation processes alone, without postulating an active splitting mechanism.

Urbild und Abbild. Leibniz, Kant und Hausdorff über das Raumproblem

The article attempts to reconsider the relationship between Leibniz’s and Kant’s philosophy of geometry on the one hand and the nineteenth century debate on the foundation of geometry on the other. The author argues that the examples used by Leibniz and Kant to explain the peculiarity of the geometrical way of thinking are actually special cases of what the Jewish-German mathematician Felix Hausdorff called “transformation principle”, the very same principle that thinkers such as Helmholtz or Poincaré applied in a more general form in their celebrated philosophical writings about geometry. The first two parts of the article try to show that Leibniz’s and Kant’s philosophies of geometry, despite their differences, appear to be preoccupied with the common problem of the impossibility to grasp conceptually the intuitive difference between two figures (such as a figure and its scaled, displaced or mirrored copy). In the third part, it is argued that from the perspective of Hausdorff’s philosophical-geometrical reflections, this very same problem seems to find a more radical application in Helmholtz’s or Poincaré’s thought experiments on the impossibility of distinguishing distorted copies of our universe from the original one. I draw the conclusion that in Hausdorff’s philosophical work, which has received scholarly attention only recently, one can find not only an original attempt to frame these classical arguments from a set-theoretical point of view, but also the possibility of considering the history of philosophy of geometry from an uncommon perspective, where especially the significance of Kant’s infamous appeal to “intuition” can be judged by more appropriate standards.
