The Copernican revolution with which Kant transformed the question of whether knowledge is possible into the query as to how knowledge is possible, constitutes one stage in the development of epistemology from a speculative to an observational science — i.e., one that proceeds from the investigation of concrete, existent objects rather than from a small number of presupposed concepts. This path, leading from speculation to examination of the concrete objects of research — for epistemology, to the investigation of the various (...) individual sciences — is long and arduous, and even now it has been traversed only a small part of the way. Although epistemological research has for a long time had some relation to mathematics and physics, and a more concrete exploration of biology and the humanities has recently been launched as well, we undoubtedly still stand at the very beginning of this enterprise. One major task for the epistemological inquiry into a specific discipline is bound up with tracing the course of development of that science — in particular, the radical shifts and readjustments in a science that promise to furnish the epistemologist with valuable information. Seen from this angle, psychology also currently deserves the special attention of epistemology. (shrink)

The ArgumentThe notion that experimentation provides an appropriate means for acquiring valid knowledge about some aspects of social reality has always depended on certain presuppositions about the nature of social reality and about the role of expenment in knowledge acquisition. In this paper I examine historical changes in these presuppositions from the beginnings of social psychological experimentation to the period after World War II.It was late nineteenth-century crowd psychology that provided the theoretical inspiration fo the first systematic steps in the (...) application of expermental methods to the investigation of social psychological problems. The basic question addressed by these early experiments was derived from the individualistic social ontology of crowd psychology. It was this ontology that made the microcosm of the experimental situation appear relevant to social reality outside this situation.In the 1940s experimental social psychology was briefly influenced by a nonindividualistic social ontology for which group phenomena were real. In the work of Kurt Lewin this was linked to an anti-inductivist conception of experimentation derived from Gestalt psychology and the philosophy of Ernst Cassirer. However, this model proved to be utterly unassimilable by American social psychology which was dominated by an individualistic social ontology and an inductivist philosophy of experimentation that mutually supported each other.

Kurt Lewin's essay “Gesetz und Experiment in der Psychologie” of 1927, published in this issue of SiC for the first time in English translation, and his “Der Übergang von der aristotelischen zur galileischen Denkweise in Biologie und Psychologie” of 19311 have together contributed most to shape his image as a metatheorist of psychology. A careful examination of what has occasionally been called the “Lewinian tradition,”2 however, reveals that Lewin's metascientific contributions have been much more influential in Europe (...) than in the United States, where he lived and taught as a Jewish refugee from 1934 until his early death on 2 February, 1947.

This paper re-examines Kurt Lewin's classic leadership studies, using them as a concrete example to explore his wider legacy to social psychology. Lewin distinguished between advanced “Galileian” science, which was based on analysing particular examples, and backward “Aristotelian” science, which used statistical analyses. Close examination of the way Lewin wrote about the leadership studies reveals that he used the sort of binary, value-laden concepts that he criticised as “Aristotelian”. Such concepts, especially those of “democracy” and “autocracy”, (...) affected the way that he analysed the results and the ways that later social scientists have understood, and misunderstood, the studies. It is argued that Lewin's famous motto—“there is nothing as practical as a good theory”—is too simple to fit the tensions between the leadership studies and his own views of what counts as good theory.

Dirk Paul Bogner widmet sich der Frage, welche Relevanz Kurt Lewins Feldtheorie im Bereich der pädagogischen Diagnostik haben könnte. Er untermauert die These, dass die Lewin’sche Feldtheorie eine völlig neue Sicht auf Lern-, Entwicklungs- und Erziehungsprozesse eröffnen würde, und legt dar, inwiefern die Einbeziehung der Dimension des Raumes die Analyse dieser erziehungswissenschaftlich relevanten Topoi verfeinern könnte. Er erörtert mittels hermeneutischer Textauslegung und vergleichender Dokumentenanalyse, warum Lewin keine erziehungswissenschaftliche Resonanz erzeugen konnte, obwohl in der Erziehungswissenschaft auch heute noch (...) intensiv Begriffe, die entweder direkt aus der Feldtheorie stammen oder aber von dieser konsequent definiert wurden, verwendet werden.

Summary With regard to the dynamics of human experience and behavior, Gestalt theoretical psychotherapy (GTP) relies mainly on Kurt Lewin’s dynamic field theory of personality. GTP is carried out by including a re-interpretation of Lewin’s theory in some aspects of psychotherapeutic practice in relation to critical realism. Human experience and behavior are understood to be functions of the person and the environment (including the other individuals therein) in a psychic field (life space), which encompasses both of these (...) mutually dependent factors. The anthropological model of this approach is, therefore, not mono-personal but, a priori, structural and relational in nature. It does not one-sidedly focus on the “inner components” of a person, but on the interrelation of the individual and a given environment, which affects experience and behavior. After a brief introduction of these basic concepts, this lecture will focus especially on Lewin’s concept of tension-systems, which may be considered as the Gestalt theoretical counterpart of Freud’s drive theory. Further, we define the basic assumptions which underlie GTP and explain how the person moves through her/his life experience in terms of Gestalt psychology. (shrink)

In the early 1920s, Hans Reichenbach and Kurt Lewin presented two topological accounts of time that appear to be interrelated in more than one respect. Despite their different approaches, their underlying idea is that time order is derived from specific structural properties of the world. In both works, moreover, the notion of genidentity--i.e., identity through or over time--plays a crucial role. Although it is well known that Reichenbach borrowed this notion from Kurt Lewin, not much has (...) been written about their relationship, nor about the way Lewin implemented this notion in his own work in order to ground his topology. This paper examines these two early versions of the topology of time, and follows the extent of Lewin’s influence on Reichenbach’s proposal. (shrink)

The relationship between Kurt Lewin and Lev S. Vygotsky is important for many methodological questions raised by the two psychologists such as distinguishing a genetic and an accidental event type. The concept of „Gestalt“ is another important issue. The present article analyzes and contextualizes the significance of this concept in their discussions since they met in Berlin in 1925. It can be shown that a difference between Lewin’s and Vygotsky’s approach becomes salient in the ways they refer (...) to Gestalt theory as a holistic approach. While Lewin understands the here-and-now of situation in which an event occurs as depending on the present field forces as a whole, Vygotsky agrees largely with Lewin’s postulate to consider all field forces, but then moves on from the field as an originally spatial model to introduce a semantic model. According to Vygotsky this is necessary to theorize fluidity and flexibility in behavior and thus to understand the necessary psychologically preconditions for free will and independency. (shrink)

Summary In this article, classical writings of Kurt Lewin (1890-1947) and Wolfgang Metzger (1899-1979) concerning education for democracy and tolerance are presented. Starting with a definition of „group” and the discussion of the meaning of groups for the individual life, especially the experimental studies of Kurt Lewin, Ronald Lippitt and Raph K. White in 1937/38 on different group atmospheres under the influence of „democratic” vs. „autocratic” vs. „laissez faire” leading style are presented again, in order to (...) give an example for the meaning of atmosphere influences on personal development, creativity and aggression – all topics concerning actual school situations and the daily experience of pupils and teachers. The collection of writings concerning education for democracy and tolerance include some of Lewin’s writings on minority problems and Metzger’s fundamental thougts on political education as a special application of productive thinking in Wertheimer’s sense. Some possibilities of how to change prejudices and to develop tolerance in Lewin’s and Metzger’s sense are presented. As a conclusion, some ideas for actual school life and possibilities to make pupils tolerant and able to participate actively in a democratic society are developed. (shrink)

The Gestalt psychologist Kurt Lewin called for a “psychological ecology” that would bring to light the social structures serving as the context for individual action and choice in everyday life. He envisioned social and physical environmental structures affecting the individual at a “boundary” within psychological experience. But how are we to conceptualize the manner in which such environmental structures influence individual experience and action? After all, the “nonpsychological” and the psychological domains are typically framed in quite different conceptual (...) language, and, in some cases, at different levels of analysis. This paper examines this question with respect to two bodies of work. In the case of perception, Fritz Heider’s pioneering analysis of perception, followed decades later by James Gibson’s ecological approach to perception, illuminated the significance of a medium for perceiving that conveys structure specific to environmental entities. As for action among community structures, Roger Barker’s research revealed the significance of the hierarchical structure of the environment of community life, and how some higher-order structures can influence and constrain individual constituent actions nested within them. Recent treatment of the psychological boundary within the 4E cognition literature is also briefly and critically examined. (shrink)

The humanist tradition developed in the Renaissance that not only cultivated the human spirit but applied its knowledge for the purpose of improving society across various humanist and scientific disciplines is not altogether extinct. Using the erudite Swiss physician and botanist Anton Schneeberger (1530–1581) as a founding father of sorts of modern humanist medicine confronted with war, I discuss the recuperation of humanism in the twentieth century, first in the thought of psychologist Kurt Lewin (1890–1947) who, under war (...) circumstances, produced a work whose analytical acumen can still be used today, and subsequently in the creation of the discipline of narrative medicine that, unwittingly perhaps, echoes Schneeberger’s insight into the imperative of inserting storytelling into the practice of both patient- and physician-centered medicine. In the background of the argument is the existence of a new society, a martial society that functions as if there were war despite its ostensible state of peace. (shrink)

Reviews the book, The complete social scientist: A Kurt Lewin reader edited by Martin Gold . Although he is often acknowledged as one of the primary founders of American social psychology, and despite frequent citations in the literature, the actual ideas of Kurt Lewin seem to have been—more often than not—ignored or disregarded by most psychologists over the course of the last half century. Fortunately, there are a number of indications that this clearly unacceptable, decades-long neglect (...) of Lewin is being rectified. One such indication is this very thoughtfully and comprehensively assembled volume published by APA books and edited by Martin Gold. Offered as a companion volume to the also recently issued one-volume edition of two previous Lewin anthologies, Resolving Social Conflicts and Field Theory in Social Science, this anthology brings together fifteen additional articles that have been until now especially difficult for scholars to obtain. 2012 APA, all rights reserved).

The received view has it that Hans Reichenbach and his friends of the Berlin Group worked close together with the more prominent Vienna Circle. In the wake of this view, Reichenbach was often treated as a logical positivist – despite the fact that he decisively opposed it. In this chapter we follow another thread. We shall show the “third man”– besides Reichenbach and Walter Dubislav – of the Berlin Group, Kurt Grelling, as a man who could grasp the academic (...) trends of the time faster than anybody else, who was better informed about logic and philosophy of nature than his two prominent colleagues and thus, could better delineate, although tentatively, central threads of research of the Berlin Group. Grelling did this on several occasions, but most ostensibly in the last years of his life when he was focused on problems of formal ontology. On the basis of this analysis, we shall see that in the early 1920s, Reichenbach too was led by a project in ontology of science that he elaborated together with the psychologist Kurt Lewin. Moreover, Reichenbach’s later philosophy of nature was also shaped by this project. We present this direction of philosophy of science as a “road less travelled” which, however, if revived, can point to a new direction that will more closely connect philosophy and science. (shrink)

The ‘mathematical imaginary’ at work in psychology is central to the contingent history of the discipline, but is also responsible for considerable confusion and ambiguity around the ontological assumptions of psychological theories and models. Rather than reject the mathematical altogether, this article argues for an alternative form of mathematical description in psychology through the use of topology. Drawing on DeLanda’s topological account of the virtual, the relationship between psychology and ontology is progressively questioned in relation to memory. Henri Bergson’s conception (...) of duration and the pure past is juxtaposed with the topological psychology of Kurt Lewin and its notion of life space as a manifold with n-dimensions. Using a diagrammatic strategy developed by Mullarkey, an actualist account of the virtual is used to hold these distinct bodies of work together. Psychological events may be given a ‘thick description’ through the identification of topological relations and invariants. The interplay between the actual entities that are afforded in experience can be seen to be virtualized as planes of irreality. A topological approach to psychology offers the opportunity of replacing the taxonomy of essences common to the discipline with a dynamic account of invariance through homeomorphism. (shrink)

This is an important volume for rounding out our understanding of the origins and dimensions of the logical empiricist project. While the existence of a Berlin wing of logical empiricism—personified principally in Hans Reichenbach and Carl G. Hempel—has been well known, in the recent reappraisal literature the spotlight has been firmly on the Vienna Circle.

Simondon adopts some concepts of social psychology as ‘in group’ and ‘out group’, namely from Kurt Lewin and Gordon Allport, that allow him to describe the fundamental processes shaping the domain of collective individuation, and to challenge Bergson’s distinction between a ‘closed’ community and an ‘open’ society. Reconstructing Simondon’s sources is necessary to understand how he tries to provide an analysis of the social system without presupposing a given anthropology, but rather exploring different perspectives on the human/nature threshold (...) through the concept of transindividual. In his study of the social system Simondon progressively gives conceptual shape to the processes he calls transindividual thanks to the ontogenetic analysis of the phenomena of belief, work and language. In all these domains, a ‘basic community’ emerges just over the threshold of the biological group, where the structural ambivalence of all collective processes as simultaneously closed and open becomes clear. That is why Simondon does not present the concept of the transindividual as a solution to the epistemological problem of psychic and collective individuation, but rather as the ‘field’ in which a whole series of social, biological and technical dimensions can be made converge towards a science of anthropogenic processes.

Do the terms “logical positivism” and “logical empiricism” mark a philosophically real and significant distinction? There is, of course, no doubt that the first term designates the group of philosophers known as the Vienna Circle, headed by Moritz Schlick and including Rudolf Carnap, Herbert Feigl, Philipp Frank, Hans Hahn, Otto Neurath, Friedrich Waismann and others. What is debatable, however, is whether the name “logical positivism” correctly distinguishes their doctrines from related ones called “logical empiricism” that emerged from the Berlin Society (...) for Scientific Philosophy around Hans Reichenbach which included Walter Dubislav, Kurt Grelling, Kurt Lewin and a young Carl Gustav Hempel.1 The ..

The paper presents basic Gestalt psychological concepts of ego and self. They differ from other concepts in the way that they do not comprehend ego and self as fixed entities or as central controlling instances of the psyche, but as one specific organized unit in a psychological field in dynamic interrelation with the other organized units—the environment units—of this field. On this theme, well-known representatives of Gestalt theory have presented some general and special theories since the early days of this (...) approach that could partly be substantiated experimentally. They illuminate the relationship between ego and world in everyday life as well as in the case of mental disorders. Not only the spatial extension of the phenomenal ego is subject to situational changes, but also its place in the world, its functional fitting in this world, its internal differentiation, its permeability to the environment, and much more. The German Gestalt psychologist Wolfgang Metzger emphasizes the significant functional role that this dynamic plasticity of the phenomenal world and its continuously changing segregation of ego and environment have for human life by designating the phenomenal world as a “Central Steering Mechanism.” In this article, ego and self as part of this field in their interrelation with the total psychological field will be illuminated from the perspective of the thinking of the Gestalt psychologists Max Wertheimer, Kurt Koffka, Wolfgang Köhler, Kurt Lewin, Wolfgang Metzger, Mary Henle, Edwin Rausch, and Giuseppe Galli.

Although in core business practice most leaders are aware of the fact that information needs to be acquired from a wide range of sources, decision makers in corporate enterprises seem to forget this and all they do, in most cases, is ask their consumers and potential customers in the course of planning their CSR (Corporate Social Responsibility) activities. There are only few companies where managers refer to ethical principles as an argument for social contribution and the connection between CSR and (...) sustainability is being rarely explored. This article is based on research (interviews and questionnaires), observations and continuous action research carried out by the Kurt Lewin Foundation. The study focuses on the communication of social responsibility since according to our experience in most cases companies undertake causes in order to improve their own image and for marketing reasons. This article concludes that the reason for difficulties in finding the best CSR solutions for enterprises and creating the commitment of their employees for the undertaken cause is that they do not think of CSR as a consequence of ethical core business process, but rather as a separate task they try to complete aiming at short-term results and maximum benefits.

It is a well-known fact that mathematics plays a crucial role in physics; in fact, it is virtually impossible to imagine contemporary physics without it. But it is questionable whether mathematical concepts could ever play such a role in psychology or philosophy. In this paper, we set out to examine a rather unobvious example of the application of topology, in the form of the theory of persons proposed by Kurt Lewin in his Principles of Topological Psychology. Our aim (...) is to show that this branch of mathematics can furnish a natural conceptual system for Gestalt psychology, in that it provides effective tools for describing global qualitative aspects of the latter’s object of investigation. We distinguish three possible ways in which mathematics can contribute to this: explanation, explication and metaphor. We hold that all three of these can be usefully characterized as throwing light on their subject matter, and argue that in each case this contrasts with the role of explanations in physics. Mathematics itself, we argue, provides something different from such explanations when applied in the field of psychology, and this is nevertheless still cognitively fruitful. (shrink)

Hans Reichenbach’s posthumous book The Direction of Time ends somewhere between Socratic aporia and historical irony. Prompted by Feynman’s diagrammatic formulation of quantum electrodynamics, Reichenbach eventually abandoned the delicate balancing between the macroscopic foundation of the direction of time and microscopic descriptions of time order undertaken throughout the previous chapters in favor of an exclusively macroscopic theory that he had vehemently rejected in the 1920s. I analyze Reichenbach’s reasoning against the backdrop of the history of Feynman diagrams and the current (...) practice of particle physics. Building upon the debates about processes and conserved quantities between Wesley Salmon and Phil Dowe in the 1990s, and the exchange between Reichenbach and the gestalt theorist Kurt Lewin during the 1920s about topology and genidentity, I investigate whether the aporia about local time order could be avoided by following a strategy that Reichenbach adopted elsewhere in the book and develop a notion of functional genidentity that captures the practice of present-day elementary particle physics and the fact that Feynman diagrams have to be understood in the context of a complex mathematical description of scattering processes.

One reason for the renewed interest in Austrian philosophy, and especially in the work of Brentano and his followers, turns on the fact that analytic philosophers have become once again interested in the traditional problems of metaphysics. It was Brentano, Husserl, and the philosophers and psychologists whom they influenced, who drew attention to the thorny problem of intentionality, the problem of giving an account of the relation between acts and objects or, more generally, between the psychological environments of cognitive subjects (...) and the different sorts of external (physical, geographical, social) environments which they inhabit. The present essay addresses this environmental version of the problem of intentionality. It draws not only on the work of Husserl and Scheler but also on the Gestalt psychological writings of Kurt Koffka and Kurt Lewin. It considers the influential subjective idealist theory of animal environments put forward by J. von Uexküll and contrasts this with a realist theory of organism-environment interaction based on the work of the ecological psychologists J. J. Gibson and Roger Barker. This realist theory is then exploited as a basis for an ontology of social objects of a range of different sorts.

What makes a choice difficult, beyond being complex or difficult to calculate? Characterizing difficult choices as posing a special challenge to the agent, and as typically involving consequences of significant moment as well as clashes of values, the article proceeds to compare the way difficult choices are handled by rational choice theory and by the theory that preceded it, Kurt Lewin's "conflict theory." The argument is put forward that within rational choice theory no choice is in principle difficult: (...) if the object is to maximize some value, the difficulty can be at most computational. Several prototypes of choices that challenge this argument are surveyed and discussed ; special attention is given to difficult choices faced by doctors and layers. The last section discusses a number of devices people employ in their attempt to cope with difficult choices: escape, "reduction" to non-difficult choices, and second-order strategies. (shrink)

The paper introduces the concepts at the heart of point-set-topology and of mereotopology (topology founded in the non-atomistic theory of parts and wholes) in an informal and intuitive fashion. It will then seek to demonstrate how mereotopological ideas can be of particular utility in cognitive science applications. The prehistory of such applications (in the work of Husserl, the Gestaltists, of Kurt Lewin and of J. J. Gibson) will be sketched, together with an indication of the field of possibilities (...) in linguistics, perceptual psychology, cate¬gorization and geographic information systems. Topological structures will be shown to play a central role in studies of naive physics not least in virtue of the fact that even well-attested departures from true physics on the part of common sense leave the topology and vectorial orientation of the underlying physical phenomena invariant: our common sense would thus seem to have a veridical grasp of the topology and broad general orientation of physical phenomena, both static and dynamic, even where it illegitimately modifies the relevant shape and metric properties. The implications of this and related insights for the methodology of psychology will be explored. (shrink)

The relationship between place and remembering has been a long-standing matter of phenomenological concern. The role of the 'lived body' in mediating acts of remembering in context is clearly crucial. In this paper we contribute to an 'expanded view of memory' by describing how remembering difficult or problematic events -- 'vital memories' -- draws upon inter-subjective and inter-objective relations. We discuss two conceptual tools that provide an analytic framework -- the concept of 'life space' drawn from Kurt Lewin (...) and the idea of the 'setting specificity' of remembering. From this perspective we can see that the 'lived body' does not constitute a singular unity but rather a 'plurality' of potential bodies that have 'operative solidarity' with the material relations in which they are constituted. Drawing on the work of Eduardo Viveiros de Castro, we argue that 'body memories' need to be analysed from within the embodied material-relational perspective wherein they are afforded. (shrink)

The author asks whether there was a “scientific ‘68”, and focuses on aspects of two specific methodological proposals defined in the 1940s and 50s by the terms “action research” and “mixing methods”, applied particularly to social sciences. In the first, the climate surrounding the events of 1968 contributed to heightening the participative element to be found –by definition– in “action research”; that is: the importance of making the research subjects themselves participants in the design, execution and application of the study (...) of which they are the focus. This approach captured the democratic and anti-authoritarian spirit at the heart of the proposal, which was part of the prevailing climate in those days. The repercussions of 1968 on “mixing methods” focused on studying what had actually occurred, especially between the youth and workers, and therefore, particularly from the point of view of sociology and social psychology, using a “mixed methods” approach. The author explores the proposal of Norman Denzin; but traces the recent origins of both “mixing methods” and “action research” back to the proposals of mainly Kurt Lewin and the Chicago School.

This paper is concerned with the representation in academic journal articles and textbooks of an organisation theory. In the case of Burns’ and Stalker’s book The Management of Innovation (1961,1966), summaries of the text by other scholars have arguably differed from the original authors and among themselves in their emphases. Similar points have been made about representations of other theorists such as Kurt Lewin and, perhaps most famously, Adam Smith. They all raise issues about the meanings of texts (...) and where such meanings lie: with the author, the reader, the text itself or perhaps some combination of these. They also raise questions about whether texts can be shown to have definitive meanings; and if not, whether there are any criteria for adjudicating on the validity of varied interpretations. Representations by textbook writers are analysed and questions about the meaning of texts raised by ‘structuralist’ and ‘deconstructionist’ writers examined. Their writings beg certain questions about textual representations. Perhaps the most extreme of these views is Barthes’ concept of the ‘death of the author’. Like Barthes, Derrida argues, for the reasons mentioned above, that there is no underlying, final decipherable meaning in a text, but gives more credence to the role of the author, accepting the validity of the author’s consciousness and intentions as one of the sources of meaning in texts. There are also other sources: the situatedness and historical context of the text and the text itself. Derrida’s concept of ‘différance’ requires the reader to engage in an analysis of the text which offers limitless possibilities for interpretation and a renunciation of the certainty of truth, because the meaning of a text may extend beyond the limits of our knowledge at any one time. His notion of the ‘logic of supplementarity’ is a further means to analyse texts, as it also disprivileges obvious or overt meanings in texts by overturning hierarchy in oppositions and questioning univocal definitions of meaning. Questions inspired by these and other writers give rise to an exploration of who is speaking in the text; which subject matter is represented as central and which as marginal; binary oppositions within the text and intertextual connections. The paper then begins the more ambitious task of answering the broader question as to whether it can be shown that there are more and less ‘representative’ or ‘stronger’ interpretations of a text.

Braddon-Mitchell and Miller put forward the claim that the relation of being-the-same-person is gradable: a person can be the same person tomorrow as today, but only half the same. To justify their thesis, they propose a model of persons that is intended to be metaphysically neutral. This article sets out to show that such a model implicitly contains strong metaphysical assumptions that run contrary to the authors’ own statements. Using Roman Ingarden’s phenomenological ontology, we aim to demonstrate that within the (...) model in question persons exist intentionally, where this leads to a caricature rather than an adequate account of persons. In opposition to Braddon-Mitchell and Miller, we argue that the justification presented for the thesis of the gradability of the relation of being-the-same-person in fact makes it reasonable to demand that an adequate model of persons be posited. We present Kurt Lewin’s holistic topological-dynamic model, and show that in this context it is not being-the-same-person that is gradable, but rather the characteristic (of persons) that is dimension. Thus, we reject the thesis of the gradability of the relation of being-the-same-person involved in personal identity. (shrink)
