The living well of our soul

Bright flooding sunlight, fresh cut flowers in generous crystal vases, and pristine clean shelves of philosophical and psychological books in several languages welcome the visitor to Liliane Frey-Rohn's upper-story modern apartment in Zürich. Even for as amateurish a photographer as our editor, it was hard to take a bad picture of her clear features—with her luminous hair, intimate eyes and warmly curious smile. This was a young, cosmopolitan woman of 88, with a classical education and dedication to the twin ideals of scholarship and the birthing of the new consciousness of her culture. She was very pleased with the recent publication in English of her book, Friedrich Nietzsche: A Psychological Approach to His Life and Work, and was happy to talk about its evolution through her studies and close association with Carl Jung     

The generative basis of natural number concepts

Number concepts must support arithmetic inference. Using this principle, it can be argued that the integer concept of exactly ONE is a necessary part of the psychological foundations of number, as is the notion of the exact equality - that is, perfect substitutability. The inability to support reasoning involving exact equality is a shortcoming in current theories about the development of numerical reasoning. A simple innate basis for the natural number concepts can be proposed that embodies the arithmetic principle, supports exact equality and also enables computational compatibility with real- or rational-valued mental magnitudes.     

Disjunction of natural concepts

Two experiments investigated the way in which the rated membership of items in disjunctively defined categories, such as FRUITS OR VEGETABLES and PETS OR FARMYARD ANIMALS, varies as a function of membership in individual constituent categories. Items were rated for category membership and typicality in each category separately, and in their disjunction. The results showed non-Boolean effects of both overextension and underextension of the disjunctions. Typicality in the disjunction was highly predictable from constituent typicality values, using regression equations with negative interaction terms. The results are compared with similar effects for concept conjunctions and are discussed in terms of an intensional model of conceptual combination (Hampton, 1987b, 1988).     

The axiomatic method,the order of concepts and the hierarchy of sciences: an introduction

We offer an overview of some ways of examining the connections between stance and rationality, by surveying recent work on four central topics: (a) the very idea of a stance, (b) the relations between stances and voluntarism, (c) the metaphysics and epistemology that emerge once stances are brought to center stage, and (d) the role that emotions and phenomenology play in the empirical stance.     

The self and the soul

This paper explores the elusive and esoteric concepts of self and soul. After examining the psychological concept of self, as differentiated from ego, the authors present a unified theory of psychological, psychoanalytical and spiritual conceptualizations in light of Kabbalah, the Jewish mystical tradition. We suggest that understanding the self system (whether in object relations, intersubjective or interpersonal terms) is enhanced by the framework found in the Jewish mystical literature.     

The European soul

Europe, and in particular the European identity, will have to be one of the essential aspects of tomorrow's education. Language teaching must be strengthened, exchanges developed, but, above all, we must make an effort to know each other.     

Authoritarian personalities in the natural and social sciences

This research is an extension of a previous finding, that authoritarian personalities are predisposed to the social sciences and nonauthoritarians to the natural sciences. Two hypotheses were tested: (1) Within the social sciences, more authoritarian personalities enter economics and geography than psychology, social work, or sociology; and (2) between the first and last years in college, in “authoritarian departments” there is an increase, while in “nonauthoritarian departments” there is a decrease in the students' authoritarianism.     

Ludwik Fleck and the concept of style in the natural sciences

Ludwik Fleck is a pioneer of the contemporary social constructionist trend in scientific theory, where his central concept of thinking style has become standard fare. Yet the concept is too often misunderstood and simplified with serious consequences not only for Fleck studies. My essay situates Fleck??s concept of thinking style in the historical context of the 1920s and ??30s, when the notion of style was first applied to the natural sciences, in order to illustrate the uniqueness of Fleck??s concept among the uses of style by his contemporaries and, finally, to examine the epistemological, methodological, and political consequences of this distinction.     

The development of language and abstract concepts: the case of natural number

What are the origins of abstract concepts such as "seven," and what role does language play in their development? These experiments probed the natural number words and concepts of 3-year-old children who can recite number words to ten but who can comprehend only one or two. Children correctly judged that a set labeled eight retains this label if it is unchanged, that it is not also four, and that eight is more than two. In contrast, children failed to judge that a set of 8 objects is better labeled by eight than by four, that eight is more than four, that eight continues to apply to a set whose members are rearranged, or that eight ceases to apply if the set is increased by 1, doubled, or halved. The latter errors contrast with children's correct application of words for the smallest numbers. These findings suggest that children interpret number words by relating them to 2 distinct preverbal systems that capture only limited numerical information. Children construct the system of abstract, natural number concepts from these foundations.     

Feature integration in natural language concepts

Two experiments measured the joint influence of three key sets of semantic features on the frequency with which artifacts (Experiment 1) or plants and creatures (Experiment 2) were categorized in familiar categories. For artifacts, current function outweighed both originally intended function and current appearance. For biological kinds, appearance and behavior, an inner biological function, and appearance and behavior of offspring all had similarly strong effects on categorization. The data were analyzed to determine whether an independent cue model or an interactive model best accounted for how the effects of the three feature sets combined. Feature integration was found to be additive for artifacts but interactive for biological kinds. In keeping with this, membership in contrasting artifact categories tended to be superadditive, indicating overlapping categories, whereas for biological kinds, it was subadditive, indicating conceptual gaps between categories. It is argued that the results underline a key domain difference between artifact and biological concepts.
