Both biosemiotics and evolutionary epistemology are concerned with how knowledge evolves. (Applied) Evolutionary Epistemology thereby focuses on identifying the units, levels, and mechanisms or processes that underlie the evolutionary development of knowing and knowledge, while biosemiotics places emphasis on the study of how signs underlie the development of meaning. We compare the two schools of thought and analyze how in delineating their research program, biosemiotics runs into several problems that are overcome by evolutionary epistemologists. For one, by emphasizing signs, biosemiotics (...) needs to delineate a semiotic threshold, which is a problem not encountered by evolutionary epistemologists. Instead, the latter recognizes that all organisms are knowers that evolve knowledge, which they recognize to extend toward phenomena produced by organisms such as behavior, cognition, language, culture, science, and technology. Secondly, biosemiotics attempts at continuing adaptationist notions on how organisms relate to their environment, while especially Applied Evolutionary Epistemology comes to redefine the nature of the organism–environment relationship in such a way that it recognizes the spatiotemporal boundedness of existence, which in turn makes adaptationist accounts obsolete.

This paper surveys questions about the nature of the Modern Synthesis as a historical event : was it rather theoretical than institutional? When and where did it actually happen? Who was involved? It argues that all answers to these questions are interrelated, and that systematic sets of answers define specific perspectives on the Modern Synthesis that are all complementary.

There is nowadays consensus in the community of didactics of science regarding the need to include the philosophy of science in didactical research, science teacher education, curriculum design, and the practice of science education in all educational levels. Some authors have identified an ever-increasing use of the concept of ‘theoretical model’, stemming from the so-called semantic view of scientific theories. However, it can be recognised that, in didactics of science, there are over-simplified transpositions of the idea of model. In this (...) sense, contemporary philosophy of science is often blurred or distorted in the science education literature. In this paper, we address the discussion around some meta-theoretical concepts that are introduced into didactics of science due to their perceived educational value. We argue for the existence of a ‘semantic family’, and we characterise four different versions of semantic views existing within the family. In particular, we seek to contribute to establishing a model-based didactics of science mainly supported in this semantic family. (shrink)

The problem analysed in this paper is whether we can gain knowledge by using valid inferences, and how we can explain this process from a model-theoretic perspective. According to the paradox of inference (Cohen & Nagel 1936/1998, 173), it is logically impossible for an inference to be both valid and its conclusion to possess novelty with respect to the premises. I argue in this paper that valid inference has an epistemic significance, i.e., it can be used by an agent to (...) enlarge his knowledge, and this significance can be accounted in model-theoretic terms. I will argue first that the paradox is based on an equivocation, namely, it arises because logical containment, i.e., logical implication, is identified with epistemological containment, i.e., the knowledge of the premises entails the knowledge of the conclusion. Second, I will argue that a truth-conditional theory of meaning has the necessary resources to explain the epistemic significance of valid inferences. I will explain this epistemic significance starting from Carnap’s semantic theory of meaning and Tarski’s notion of satisfaction. In this way I will counter (Prawitz 2012b)’s claim that a truth-conditional theory of meaning is not able to account the legitimacy of valid inferences, i.e., their epistemic significance. (shrink)

The criticisms levelled at the notion of truth by an anti-realist and an entity-realist are critically examined. The upshot of the discussion will be that whilst neither of the two anti-truth philosophers have succeeded in establishing their cases against truth, for entity-realists to reject the notion of truth is to throw out the baby with the bath water: entity-realism without the notion of correspondence truth will degenerate into anti-realism.

In this article, we argue for a study of educational administration centered on an ontology of practices. This is an initial proposal for thinking about and conceptualizing practices in educational administration. To do this, first, we explore how practices are constituted and how they configure the social realities of practitioners. Second, we explore what an ontology of practices has to offer for our understanding of organizations. Third, we examine how an ontology of practices might inform our understandings of leadership in (...) educational organizations, and we conclude by exploring some implications of an ontology of practices for the study of educational administration.

The term “evolution” is often used in the administrative sciences to designate dynamic processes of change in general. In biology, evolution has a very specific meaning, namely the application of a generative variation-selective retention scheme to change. Applying this to the administrative sciences is more exacting: describing what the variation consists of, how replication of the generated variation occurs and delineating the population from which the selection is made are far from easy. While it is the intention of this special (...) issue as a whole to provide some empirical examples of evolutionary change in the public and private sectors, this introduction will lay out the main lines of thought in what is often referred to as universal Darwinism and what this means in the administrative sciences. Key concepts here are generative variation, selective retention, and selective institutional environment. According to the authors, the Darwinian scheme of evolutionary theory focuses on how new ideas or concepts arise, how they propagate and influence wider actor thinking and on how the institutional environment in which they operate affects their differential survival. This evolutionary process is an interplay between actors and replicators (sounds, images, and in this context mostly words) in which it cannot be said in advance which one is fooling the other.

Classifying is a fundamental operation in the acquisition of knowledge. Taxonomic theory can help students of cognition, evolutionary psychology, ethology, anatomy, and sociobiology to avoid serious mistakes, both practical and theoretical. More positively, it helps in generating hypotheses useful to a wide range of disciplines. Composite wholes, such as species and societies, are “individuals” in the logical sense, and should not be treated as if they were classes. A group of analogous features is a natural kind, but a group of (...) homologous features is not. Imposing hypotheses justified only on the basis of nominalist, realist, phenomenalist, or conceptualist metaphysics upon the neurophysiology of organisms or upon the causes of behavior exemplifies the “psychologist's fallacy” of William James. Levels should be distinguished from their members and from classes of levels, and the ontological status of entities ranked at levels should be made clear. It is important not to confuse such categories as substance and process with one another. Several genetical terms, such as “gene” and chromosome,” are even more equivocal than has been realized. Discussions about units of selection, behavior, and thinking suffer from the ambiguity of a “unit of” an entity. An important source of misunderstanding about natural selection is the habit of treating it as an “agent”: in an important sense, natural selection does not “act” at all. (shrink)

In this article, against the background of a notion of ‘assembled’ truth, the evolutionary progressiveness of a theory is suggested as novel and promising explanation for the success of science. A new version of realism in science, referred to as ‘naturalised realism’ is outlined. Naturalised realism is ‘fallibilist’ in the unique sense that it captures and mimics the self-corrective core of scientific knowledge and its progress. It is argued that naturalised realism disarms Kyle Stanford’s anti-realist ‘new induction’ threats by showing (...) that ‘explanationism’ and his ‘epistemic instrumentalism’ are just two positions among many on a constantly evolving continuum of options between instrumentalism and full-blown realism. In particular it is demonstrated that not only can naturalised realism redefine the terms of realist debate in such a way that no talk of miracles need enter the debate, but it also promises interesting defenses against inductive- and under-determination-based anti-realist arguments.

Class discussions about ethical, social, philosophical and other controversial issues frequently result in disagreement. This leaves a problem: has there been any progress? This article introduces and analyses the concept ‘collective epistemic progress’ in order to resolve this problem. The analysis results in four main ways of understanding, guiding and judging collective epistemic progress in the face of seemingly irreconcilable differences. Although it might seem plausible to analyse and judge collective epistemic progress by the increasing vigour of the dialogue community, (...) by how long the conversation is continued, or by how close we have moved towards consensus or the truth, I argue that these fail to provide serviceable analyses or epistemic criteria. Yet, we might instead analyse, understand and judge progress using epistemic criteria such as whether we have: furthered the one distributed process of inquiry or deliberation; and reached mutual understanding; inquiry milestones; or consensus about our procedures.

This essay explores the dialectics of theory and practice in terms of argumentation theory. Adapting Jonsen and Toulmin's (1988) notion of a Theory-Practice spectrum, it conceives Theory and Practice as extreme ends of a continuum and discourses as falling at various points along the continuum. Every theoritical discourse has essential practical aspects, and every practical discourse has essential theoretical aspects. Practices are theorized to varying degrees but every practice is thorized to some degree. Reflective discourse, which is discourse about practice, (...) moves to and fro along the Theory-Practice continuum. Reflective discourse involves argumentation. Practical argumentation connects theory to practice; it appeals to general warrants, which may be simple or may tap into elaborate conceptual structures, in order to establish grounds for practical judgments. A practical discipline is a relatively coherent intellectual-professional enterprise that cultivates a field of social practice by engaging within itself and with practitioners in a reflective discourse. The argumentation of a practical discipline, like ordinary practical reflection, moves to and fro along the Theory-Practice continuum but in more methodical steps informed by systematic methodological reflection on the reflective process itself.

The Three Papers comprising this series, together with my earlier [34] also published in this journal, constitute an attempt to set out the major issues in the theoretical domain of reduction and to develop a general theory of theory reduction. The fourth paper, [34], though published separately from this trio, is integral to the presentation and should be read in conjunction with these papers. Even so, the presentation is limited in scope – roughly, to intertheoretic reduction among empirical theories – (...) and informal in presentation – not least because a satisfying formal account of theories has yet to be offered. And despite the length, the treatment is still condensed; often corroborating and/or intuitively helpful detail has had to be consigned to footnotes or omitted. I approach the problem from within my own naturalistic realist philosophy of science and formal analysis of abstract hierarchy in theory. The sources for the former are [25], [29], [31], and [32] and those for the latter essentially [27] and [30]. Hierarchical notions played a significant role in the already published [34]. (shrink)

According to the instrumentalism of Friedman and Machlup it is irrelevant whether the explanatory principles or “assumptions” of a theory satisfy any criterion of “plausibility,” “realism,” “credibility,” or “soundness.” In this view the main or only criterion for selecting theories is whether a theory yields empirically testable implications that turn out to be consistent with observations. All we should require or expect from a theory is that it is a useful instrument for the purpose of prediction. Considerations of the “efficiency” (...) of a theory for the purpose of ordering our experiences are permitted, but considerations of “plausibility” are not. “Explanatory assumptions” are not really explanatory in the sense that they claim to represent underlying causal processes in reality; they only serve to generate, by deduction, implications that are in accordance with as many observations as possible.

Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative hypothesis formation is guided (...) rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

Aspects of the controversy concerning the theoretical status of some recent thinking on human cognition are discussed; in particular, the concept of ?unconscious knowledge?, the ?functionalist? analysis of the mental; the problem of the domains of explananda, given the recalcitrant difficulty in providing warrantable and generalizable criteria for individuating components of an organism's ?behavior'; the problem of the polymorphous character of various mental predicates and their misconceived treatment as ?state? or ?process? descriptors; the possible ?over?intellectualizing? of central?nervous?system processes, and the (...) availability of an alternative program for the ?middle?ground? between common?sense reasoning and neuroscientific research in the study of ?mind?. Throughout the discussion, a broadly neo?Wittgensteinian approach is advanced. (shrink)

An explicit philosophy and meta-philosophy of positivism, empiricism and popperianism is provided. Early popperianism is argued to be essentially a form of empiricism, the deviations from empiricism are traced. In contrast, the meta-philosophy and philosophy of an evolutionary naturalistic realism is developed and it is shown how the maximal conflict of this doctrine with all forms of empiricism at the meta-philosophical level both accounts for the form of its development at the philosophical level and its defense against attack from nonrealist (...) quarters. Following an earlier article on realism of similar theme (Synthese 26 (1974), 409) this paper then further explores the ramifications of a thoroughgoing realist position. (shrink)

There are two interrelated but distinct programs which go by the name evolutionary epistemology. One attempts to account for the characteristics of cognitive mechanisms in animals and humans by a straightforward extension of the biological theory of evolution to those aspects or traits of animals which are the biological substrates of cognitive activity, e.g., their brains, sensory systems, motor systems, etc. (EEM program). The other program attempts to account for the evaluation of ideas, scientific theories and culture in general by (...) using models and metaphors drawn from evolutionary biology (EET program). The paper begins by distinguishing the two programs and discussing the relationship between them. The next section addresses the metaphorical and analogical relationship between evolutionary epistemology and evolutionary biology. Section IV treats the question of the locus of the epistemological problem in the light of an evolutionary analysis. The key questions here involve the relationship between evolutionary epistemology and traditional epistemology and the legitimacy of evolutionary epistemology as epistemology. Section V examines the underlying ontological presuppositions and implications of evolutionary epistemology. Finally, section VI, which is merely the sketch of a problem, addresses the parallel between evolutionary epistemology and evolutionary ethics. (shrink)

The article addresses the question whether culture evolves in a Lamarckian manner. I highlight three central aspects of a Lamarckian concept of evolution: the inheritance of acquired characteristics, the transformational pattern of evolution, and the concept of directed changes. A clear exposition of these aspects shows that a system can be a Darwinian variational system instead of a Lamarckian transformational one, even if it is based on inheritance of acquired characteristics and/or on Lamarckian directed changes. On this basis, I apply (...) the three aspects to culture. Taking for granted that culture is a variational system, based on selection processes, I discuss in detail the senses in which cultural inheritance can be said to be Lamarckian and in which sense problem solving, a major factor in cultural change, leads to directed variation.

This paper starts from the point in the early 1970s at which educational theory and research was temporarily structured under the ‘foundation’ disciplines of psychology, sociology, philosophy and history of education. It observes the way the intellectual resources of educational research have become enlarged and enriched and these disciplines themselves fragmented and hybridised to a degree that prompts talk not just of interdisciplinarity but of ‘postdisciplinarity’. The paper argues, however, that without discipline, in the sense of a shared language, a (...) rule governed structure of enquiry—something ‘systematic’—we lose the conditions that make a community of arguers possible. Further, we lose the basis for the special claim which research might otherwise make on our attention and on our belief. (shrink)

In considering the Cambridge School of intellectual history, we should distinguish Skinner's conventionalism from Pocock's contextualism whilst recognising that both of them argue that the study of a text's linguistic context is at least necessary and perhaps sufficient to ensure understanding. This paper suggests that although "study the linguistic context of an utterance" is a valuable heuristic maxim, it is not a prerequisite of understanding that one does so. Hence, we might shift our attention from the role of linguistic contexts (...) in understanding a text, to the role of ideational contexts in our explanations of meanings or beliefs. The explanatory role of contexts can be unpacked in terms of traditions and dilemmas. Here the paper also considers how this approach differs from that of the Cambridge School. (shrink)

Science is a dynamic process in which the assimilation of new phenomena, perspectives, and hypotheses into the scientific corpus takes place slowly. The apparent disunity of the sciences is the unavoidable consequence of this gradual integration process. Some thinkers label this dynamical circumstance a ‘crisis’. However, a retrospective view of the practical results of the scientific enterprise and of science itself, grants us a clear view of the unity of the human knowledge seeking enterprise. This book provides many arguments, case (...) studies and examples in favor of the unity of science. These contributions touch upon various scientific perspectives and disciplines such as: Physics, Computer Science, Biology, Neuroscience, Cognitive Psychology, and Economics. (shrink)

Ludwig Boltzmann is one of the foremost responsible for the development of modern atomism in thermodynamics. His proposition was revolutionary not only because it brought a new vision for Thermodynamics, merging a statistical approach with Newtonian physics, but also because he produced an entirely new perspective on the way of thinking about and describing physical phenomena. Boltzmann dared to flirt with constructivism and realism simultaneously, by hypothesizing the reality of atoms and claiming an inherent probabilistic nature related to many particles (...) systems. Boltzmann faced criticism from the positivists, who rejected the hypothesis of the atom as a matter of principle, and also from physicists, who rejected the idea of a classical bounded system that does not follow deterministic mechanical laws. We consider that Boltzmann thermodynamics has emerged as a systemic theory that deals with macroscopic bodies using collective variables; it was reformulated to a kinetic theory of gases, and subsequently to statistical mechanics. From the theoretical physical point of view, Boltzmann advocates an approach to thermodynamics based on mechanics and was one of the founders of statistical mechanics, together with ideas by Maxwell, Clausius and Gibbs. Subsequently, statistical mechanics has also influenced the development of quantum mechanics and information theory. Using an evolutionary epistemological perspective as a metaphor to describe the physical entities claimed in Boltzmann propositions, we interpret his work as a selected theory that gained attributes of reality and “survived” during a scientific-contextual competition to be more adapted, in the sense that it was able to better explain physical phenomena, and also generated “descendants”.

This paper presents an analysis of the structure of contemporary sociological knowledge in terms of a theory of scientific discourse. The concept of 'discourse' is introduced as a theoretical refinement of the concept of 'paradigm' and is applied to the classes of knowledge claims of the natural and social sciences. It is concluded that general modes of scientific discourse are definable in terms of their vertical differentiation from everyday discourse, while particular modes of sociological discourse are additionally definable in terms (...) of their horizontal differentiation. A classification is then proposed which identifies three modes of sociological discourse: natural, technical and formal. (shrink)

It is argued that fundamental to Piaget's life works is a biologically based naturalism in which the living world is a nested complex of self-regulating, self-organising (constructing) adaptive systems. A structuralist-rationalist overlay on this core position is distinguished and it is shown how it may be excised without significant loss of content or insight. A new and richer conception of the nature of Piaget's genetic epistemology emerges, one which enjoys rich interrelationships with evolutionary epistemology. These are explored and it is (...) shown how a regulatory systems evolutionary epistemology may be embedded within genetic epistemology. (shrink)

Toulmin’s original models of argumentation and human reasoning are reexamined in this paper from the perspective of evolutionary and cognitive theory. On the basis of recent work done from the biological and adaptationist perspectives in communication studies, it is to be demonstrated how neo-Darwinian and cognitive psychology may provide the platform for an understanding of the relationship of argumentation to human reasoning and communicative faculties. The Toulmin’s notions of field dependence and independence in argument are then reexamined and reappraised in (...) light of this approach. (shrink)

This short paper is about the generalized evolutionary approach to the economics of science. Stephen Toulmin and David Hull are pioneers of the former rather than Karl Popper whose falsification thesis was sociologically naive. Useful directions for the future would go beyond the generalities of variation, transmission and selection towards making more explicit use of Darwin’s “two great principles.” The first is “the unity of types” i.e. common descent by employing phylogenetic methods to answer historical questions. The second is “the (...) conditions of existence” i.e. natural selection by making use of general principles of evolutionary ecology and socioecology to answer questions about why something evolved.

Paul Hirst claimed that Richard Peters ?revolutionised philosophy of education?. This does not accord with my experience in the Antipodean periphery. My experience of the work of Wittgenstein, Austin and Kovesi before reading Peters and Dewey, Kuhn and Toulmin subsequently meant that Peters was a major but not revolutionary figure in my understanding of philosophy of education.

The interpretive plasticity of Kuhn’s philosophical work has been reinforced by readings informed by other philosophical, historiographic or sociological projects. This paper highlights several aspects of Kuhn’s work that have been neglected by such readings. First, Kuhn’s early contribution to several subsequent philosophical developments has been unduly neglected. Kuhn’s postscript discussion of “exemplars” should be recognized as one of the earliest versions of a conception of theories as “mediating models.” Kuhn’s account of experimental practice has also been obscured by readings (...) that assimilate his views to Quinean holism. Second, three distinctive Kuhnian themes have been insufficiently recognized. Kuhn’s challenge to received philosophical views has been domesticated by reading him as offering an alternative conception of scientific knowledge. Kuhn is better understood as rejecting knowledge-centric accounts altogether, in favor of understanding the practice of research. Kuhn’s conception of that activity, as conceptual “articulation,” has accordingly also not been given its due. Finally, Kuhn’s career-long insistence on the mutual accountability of philosophy of science and the philosophy of mind and language calls attention to the extent to which these fields have now drifted apart.

This essay offers some reflections on the recent history of the disputes about the relation between history and philosophy of science (HPS) and the merits and prospects of HPS as an intellectual endeavor. As everyone knows, the issue was hotly debated in the 1960s and 1970s. That was the hey-day of the slogan "history without philosophy of science is blind, philosophy without history of science is empty" as well as of the many variations on the theme of HPS as a (...) "marriage of convenience," "intimate relation," or "marriage for the sake of reason."

Evolutionary theory has been a very popular topic in recent years and it has been claimed that it can make a major contribution to the advance of several sciences such as medicine, psychology, psychopathology and sociology: even providing them with new paradigms. This paper explores the possibility that nursing could benefit similarly by adopting an evolutionary perspective. After sketching the scientific and philosophical background to the recent developments concerning evolution, and briefly mentioning the chief features of evolutionary theory, the paper (...) discusses whether it makes sense to talk of ‘evolutionary nursing’, and whether there are any benefits in doing so. It uses a comparison with Darwinian medicine and evolutionary psychology. Several problems and objections are considered. The modest conclusion is reached that nurses need to adopt an evolutionary perspective to serve as a guide for some of their research and a source for research hypotheses. They also need to be informed about evolutionary ideas so as to be aware of the developments in the disciplines with which they work, and this understanding will assist them in maintaining vigilance against the misuse of science, religion and politics on behalf of their patients.

Beginning by offering a conceptual analysis of change – a statement of what change of any kind is – the paper sets out to examine possible ways of understanding a very common and important variety of change that may be called ‘evolutionary’. These changes include anything from the production of a clay pot on a potter's wheel to the emergence of a system of management, or from the effects of an analgesic drug to the development of a new programme of (...) care. As few philosophers have discussed such topics, theories are borrowed from the philosophy of science that attempt to explain the development and rationality of science. The ideas of Karl Popper and Thomas Kuhn are discussed and criticized, before turning to evolutionary theories: Darwinian and Lamarckian. The paper ends by offering a model that, it is hoped, may help in thinking about a wide range of changes. (shrink)

Definitions may seem marginal to the sociological enterprise but can be very useful; however, they can also lead to serious errors. Examples of both are given in this article. Different types of definitions are presented, and their relevance for sociology is highlighted. A stipulative definition, for example, is very useful in sociology, as opposed to lexical and ostensive definitions. The definition of a concept that is used in a sociological analysis has to be sociological in nature, and the concept cannot (...) have the same meaning as it has in everyday language. Additional items to bear in mind when a definition is put together are discussed, including some tips on how to proceed that come from political science (Sartori, Collier, Goertz). A definition can also be very helpful in the research process itself by indicating which are the important aspects of some phenomenon to focus on (Weber, Blumer). On the negative side, a term that is not properly defined may lead to misunderstandings as well as to a false sense of agreement with other uses of the term. (shrink)

Interpreting John Rawls’ ‘reflective equilibrium’ method from the perspective of Morton White’s holistic pragmatism entails both an epistemological and a methodological dimension. In this article, I reconsider White’s perspective regarding Rawls’ ‘reflective equilibrium’. This requires a critical examination of the method’s origins and development, with an emphasis on Nelson Goodman’s process of justification and the Duhem-Quine thesis. In order to examine the origins and development of the ‘reflective equilibrium’ method, I also draw upon the writings of Pierre Duhem, Willard Van (...) Orman Quine, Nelson Goodman, Stephen P. Stich and Donald Gillies, among others. Subsequently, I interpret the criticisms that have been formulated against the process of justification elaborated by Goodman and adapted by Rawls. Afterwards, I explain the conceptual links between the ‘Duhem-Quine thesis’ and the ‘reflective equilibrium’ method. In the last chapter, I analyse White’s assertion that Rawls’ theory of justice is a variant of holistic pragmatism. I emphasize how White’s holistic theses coincide to a significant extent with the ideas devised by Rawls regarding the method of ‘reflective equilibrium’ in social justice, and in a more general sense, in ethics. Also, I expound why White’s doctrine is epistemologically holistic and methodologically monistic. (shrink)

Some scholars see interdisciplinarity as a special case of a broader unificationist program. They accept the unification of the sciences as a regulative ideal, and derive from this the normative justification of interdisciplinary research practices. The crucial link for this position is the notion of integration: integration increases the cohesion of concepts and practices, and more specifically of explanations, ontologies, methods and data. Interdisciplinary success then consists in the integration of fields or disciplines, and this constitutes success in the sense (...) that unification is epistemically desirable. In contrast to this account, I defend the thesis that successful interdisciplinary interaction does not necessarily imply the integration of these disciplines. I show this at the hand of two cases. In both the case of evolutionary game theory and the case of hyperbolic discounting, genuine interdisciplinary exchange took place. From both exchanges, the respective economic fields emerged substantially altered – it wasn’t just a juxtaposition of disciplines in which disciplinary identities remained unchanged. Yet in neither case did the disciplines integrate. Rather, they developed their own concepts and methods, their own explanations, own ontologies, and their own views of what proper data standards were. Furthermore, the fields that emerged from these exchanges were very successful, if measured at the hand of properties like explanatory success, increase of control, bibliometrics and grant yields. Thus, I argue, there are cases of interdisciplinary success without integration. (shrink)
