The Meaning of Disgust is a vivid example of how interdisciplinary research can go horribly wrong. Strohminger’s criticisms serve as a good starting point to discuss some of the issues that need to be addressed by the growing number of researchers who choose to conduct interdisciplinary research in philosophy and psychology. I argue that McGinn’s approach to science in The Meaning of Disgust serves as a useful contrast to the ideal, and that it illustrates the most important virtue necessary for (...) being a good interdisciplinarian: intellectual humility.

The detailed analysis allows to discern seven kinds of integration, namely: I₁ consisting in the synthesis of scientific disciplines from their elements, including disciplinary unification I₁; I₂ inclusion of a science in (reduction to) another, more general; I₃ - links between different sciences, especially establishing of common elements; I₄ - interdisciplines bridging various sciences; I₅ - combination of two (or more) disciplines into a new (complex) science; I₆ - a general approach to several domains or multidisciplinary unification; I₇ - (...) transdisciplinary sciences about relations of the same type in various traditional domains. These kinds of integration are interwoven with processes of differentiation, viz. D₁ - internal differentiation of the sciences resulting of I₁; D₂ - interdisciplinary differentiation concomitant I₄, and D₃ - specialization of I₇ sciences in several sections. As a result integration and differentiation are combined in the pairs I₁ - D₁, I₇ - D₃, and D₂ - I₄. The processes of integration (and differentiation) may be presented schematically in the following (not strictly isolated one of another) sequence: in the 17th century started I₁ followed by D₁, and in the last decades by I₁'; during the 18th and the 19th c. cases of I₂ and I₃ appear; I₄ (together with D₂) is unfolding since the late 19th century. Finally, I₇ (and D₃), as well as I₅ and I₆ pertain to the latter half of our century. Representative are for one thing I₁, I₄, and I₇ outlining the main stages of integration and at the same time connected with respective kinds of differentiation. (shrink)

Cognition is commonly taken to be computational manipulation of representations. These representations are assumed to be digital, but it is not usually specified what that means and what relevance it has for the theory. I propose a specification for being a digital state in a digital system, especially a digital computational system. The specification shows that identification of digital states requires functional directedness, either for someone or for the system of which it is a part. In the case or digital (...) representations, to be a token of a representational type, where the function of the type is to represent.

Bioinformatics – the so-called shotgun marriage between biology and computer science – is an interdiscipline. Despite interdisciplinarity being seen as a virtue, for having the capacity to solve complex problems and foster innovation, it has the potential to place projects and people in anomalous categories. For example, valorised ‘outputs’ in academia are often defined and rewarded by discipline. Bioinformatics, as an interdisciplinary bricolage, incorporates experts from various disciplinary cultures with their own distinct ways of working. Perceived problems of interdisciplinarity include (...) difficulties of making explicit knowledge that is practical, theoretical, or cognitive. But successful interdisciplinary research also depends on an understanding of disciplinary cultures and value systems, often only tacitly understood by members of the communities in question. In bioinformatics, the ‘parent’ disciplines have different value systems; for example, what is considered worthwhile research by computer scientists can be thought of as trivial by biologists, and vice versa. This paper concentrates on the problems of reward and recognition described by scientists working in academic bioinformatics in the United Kingdom. We highlight problems that are a consequence of its cross-cultural make-up, recognising that the mismatches in knowledge in this borderland take place not just at the level of the practical, theoretical, or epistemological, but also at the cultural level too. The trend in big, interdisciplinary science is towards multiple authors on a single paper; in bioinformatics this has created hybrid or fractional scientists who find they are being positioned not just in-between established disciplines but also in-between as middle authors or, worse still, left off papers altogether.

This section includes eighty-six short original essays commissioned for the inaugural issue of TSQ: Transgender Studies Quarterly. Written by emerging academics, community-based writers, and senior scholars, each essay in this special issue, “Postposttranssexual: Key Concepts for a Twenty-First-Century Transgender Studies,” revolves around a particular keyword or concept. Some contributions focus on a concept central to transgender studies; others describe a term of art from another discipline or interdisciplinary area and show how it might relate to transgender studies. While far from (...) providing a complete picture of the field, these keywords begin to elucidate a conceptual vocabulary for transgender studies. Some of the submissions offer a deep and resilient resistance to the entire project of mapping the field terminologically; some reveal yet-unrealized critical potentials for the field; some take existing terms from canonical thinkers and develop the significance for transgender studies; some offer overviews of well-known methodologies and demonstrate their applicability within transgender studies; some suggest how transgender issues play out in various fields; and some map the productive tensions between trans studies and other interdisciplines.

In the introduction to this volume we have argued that being an interdisciplinary scholar involves managing a complex interplay of disciplinary identities, as well as the ontologies and ways of knowing and understanding that are associated with the subject matter. We argued that trying to force a bioethical interdiscipline without a special regard to the individual epistemological, ontological and social aspects of the disciplines is unlikely to bear fruit in the long-term. Although bioethics has always been a multidisciplinary activity, the (...) relations between the various disciplines involved have traditionally been fraught, particularly so at the intersection between sociological and philosophical bioethics. We therefore proposed approaching bioethical interdisciplinarity in a manner that is careful and measured. This does not involve abandoning disciplines or disciplinarity, rather we are advocating for an increased level of cross-fertilisation between established disciplines or the way in which research is done, in the broadest sense.

In the critically inherited Marxism, the Annales school and on the basis of the theory of dissipative structures, construction of a world system Wallerstein school's overall theory. Wallerstein's overall theory includes two aspects: First, the integrity of space and time. In space, the center of the modern world system is, semi-periphery and the edge of the composition of the three economic regions of the world economy or the nation-state form of the international system; in time, the modern world-system dynamic performance (...) of long-term trend and cycle rhythm . Another is the integrity of knowledge. An integrated multidisciplinary approach to construct an alternative history of interdisciplinary social sciences, natural sciences and humanities to eliminate the tension between and within different social science disciplines and between the spatial and temporal dimensions of the differences between the rules of the special theory and the binary opposition. Wallerstein's theory of deconstruction of the traditional whole social science disciplines in the national myth and myth, which we understand the history and reconstruction of historical system has important implications. By crtically inheriting Marxism, the Annales School and the Dissipative Structure Theory, Wallerstein constructs holism of world-system school, which is inclusive of two aspects: one is the entirety of TimeSpace; the other is the entirety of knowledge. In respect of space, modem world-system is constitutive of world economy or international system ; whereas in respect of time, the dynamic characteristics of modem world-system displays secular trends and the cyclical rhythms. As to the entirety of knowledge, Wallerstrin employs unidisicplinary approach in place of interdiscipline to construct historical social science whereby he intends to remove the tension between natural sciences and humanities, eliminates the TimeSpace dimension differences between various disciplines within social scieces, and dispels the dilemma between idiographic and nomothetic. Wallerstein's holism deconstructs the myth of nations and the myth of disciplines in traditional social science, which is of significant enlightment to the understanding of history and the reconstruction of historical system.

Social Information Science (or Social Informatics) is a new and interdiscipline branch subject in China. This paper probe the emergence and the research outline of social information science. 1. The proposal of the social information science. We set up the research from an extension from the theoretical informatics to the concrete informatics; a internal bond of integrating various subjects in humane and social sciences; an intersection and mutual permeation between the social science and the natural science; a the intersection and (...) interaction among humane and social sciences, modern information science and information technology; a strengthening to the research into Social Epistemology. Ⅱ. On the concept of social information. Social information directly is different with selfexistent and natural information, and more related to human’s autonomous creative activities, to society’s culture inheritance, to social value, to human’s spiritual interaction and to human’s emotions. Ⅲ.On the theoretical orientation of the social information science. Social Information Science is a concrete branch of informatics, a generation of sub-disciplines of social information, a kind of traversing and comprehensive research on individual social science from the angle of information, a kind of exchange and interaction between social theoretical research and the modern information technology. Ⅳ. The research focus of the social information science. The paper lists 10 main focus in the research of social information science. Ⅴ.The system and frame of the social information science. In general, there should be four levels of researches if the social information science is to be viewed as a relatively independent subject: the philosophical level, the scientific theoretical level, concrete apply level, social information technology and methods.

Since Neumann and Morgenstern’s theory of games, the debate among social scientists, economists, mathematicians, and social philosophers about what kind of theory it is has not ended. Some think that it is a new interdiscipline, some that it is a mere accumulation of gametheoretical models, such as utility theory, competitive, cooperative, collective choice models, and so on. Most of them agree that the models of game theory deal with isolated, single, and independent specific societal interactions between individuals who wish to (...) maximize their gains and minimize their losses within prescribed constraining rules.

Longtemps ignorée en France, la télévision a été un objet de légitimation académique des Sic. Les recherches d'abord inscrites dans l'interdiscipline mais oeuvrant dans une perspective mono ou transdisciplinaire ont donné naissance à une optique inter-disciplinaire qui a mis à jour toute sa portée heuristique. Favorisée par des mesures institutionnelles, la recherche sur ce média a permis de préciser un positionnement par rapport aux autres disciplines.Even if television remained marginal in France for a long time, it has constituted a subject (...) for the legitimisation of IC studies. It was first analysed by researchers belonging to this interdiscipline but working from a single or transdisciplinary perspective, and then apprehended from an interdisciplinary standpoint which brought to light its full heuristic scope. Research into this medium, which was recently made easier by institutional measures, has enabled those working in this field to define their position regarding other disciplines. (shrink)

The following article is the result of a collaboration between a painter and a woman philosopher. They worked previously on an experimental documentary film about objects and art objects, which was realized at Palais de Tokyo. The painter had illustrated in black and white fictions of philosophy, written during a festival on lost films organized by UNdocumenta in South Korea, and then he made photographs of oil paintings of the English translation. This article about painting and philosophical ethics is their (...) first common text. It aims to show that there is no interdiscipline or passage known between the philosophical work and the painting. The philosopher can not imitate the recognition of the painter nor the painter to repair the philosophical non-encounter. The question then is: What can ethics in this non-symmetrical space? Rather than being a product of philosophy, it is what organizes this space between recognition and non-encounter. It is an ethics for philosophy, rather than the other way around. Ethics force to greet the other philosophers without the grudge of the loss necessary to the invention and allows the painter to know the distances that make him feel the recognition. This ethical space is unknown and can not be covered by the artist's philosophy of access or pre-nomination by indexes. Ethics is this unknown, i.e. it is a sense-without-sign, it is without rules-said but process of indexation and acceptance of the loss. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.2 (2002) 96-119 [Access article in PDF] Re-Marking Slave Bodies: Rhetoric as Production and Reception Steven Mailloux There is much talk nowadays about the double nature of rhetoric: rhetoric as a practical guide for composing and rhetoric as a theoretical stance for interpreting. The two uses can be viewed as complementary, as flip sides of the same holistic approach to rhetorical studies. But they can also (...) appear in conflict: production models of writing and speaking versus reception models of reading and listening; models for inventing rhetoric versus models for analyzing it. Indeed, though the two models can be mutually supportive, they have often developed in tension within the evolution of academic disciplines over the last 125 years. Different emphases on one or the other model have resulted in different departmentalized disciplines and varied divisions within those departments, as we are all so well aware. One might even claim that advocating one or the other model has contributed significantly to the fragmentation of rhetoric as an interdiscipline during the last century and to the distribution of its parts into various academic units. In many English departments, for example, the continuing divisions between literature and composition faculty arise from contrasting professional interests in reception models focused on interpreting literary works versus production models focused on composing student texts. A similar reception/production antagonism appears in the history of speech departments separating from English departments. In 1915, when seventeen teachers of public address broke off from the National Council of Teachers of English, the production (oratory or debate) model they favored was at odds with the reception (philological or hermeneutic) model of most literature faculty. 1I don't mean to suggest that different choices between models of production and reception fully account for the academic fragmentation of rhetorical study. Nevertheless, practical antitheses do constitute disciplinary [End Page 96] identities. Antitheses between production and reception—between writing/speaking, on the one hand, and reading/listening, on the other—have variously combined with other distinctions between written texts versus oral performances as objects of study and between scientific research versus humanistic scholarship as intellectual traditions, and these assorted configurations of interpretive practices and institutional formations did help shape disciplinary identities throughout the past century. We are now faced with a situation in which rhetoric is distributed across several departments and programs, not in an integrated interdiscipline but as disciplinary fragments, where rhetorical critics in literary and cultural studies, for example, don't read deeply either in the work of rhetoric/ composition faculty in their own departments or the rhetorical scholarship produced in other departments such as communications or classics.Historically, I believe, the separation of written rhetoric (literature and composition) from oral rhetoric (public address and debate) within the academic humanities, this separation of English and speech departments, has been just as debilitating for rhetorical study as the literature/composition split within English departments alone. One might speculate about how these divisions encouraged the eventual exclusion of oratory from British and U. S. literary canons. More important, these divisions have resulted in a fragmented disciplinary approach to everything having to do with tropes, arguments, and narratives in culture, including most recently the study of local and global communication networks, old and new literacies, and past and present media revolutions.In the present essay I suggest an alternative to this disciplinary fragmentation of rhetoric. This alternative, call it rhetorical hermeneutics, learns from the more holistic approach to language arts found at the elementary and secondary levels of our U. S. educational system, where writing, speaking, reading, and listening (and sometimes viewing) are practices often taught in relation to one another. 2 Here production and reception models form parts of the same integrated framework for understanding and participating in the cultural conversations of diverse public spheres. In the following sections, I address these issues of model selection first by considering the objection that rhetorical hermeneutics is exclusively a method of reading and not a heuristic for writing. Then I move to an example of rhetorical hermeneutics in practice: a reception study of rhetorical productions... (shrink)

The aim of this paper is to show that every form of knowledge, even scientific knowledge, is linked with the personal existence that effectuates it. We offer a map of the different schools of Interdisciplinarity attending to an anthropological criterion. To this end, a map of the various schools of interdisciplinarity is offered according to an anthropological criterion, where the persistence of a partial and reductive approach to human knowledge in various modalities is generally detected. The consequence of this way (...) of understanding knowledge is firstly the fragmentation of reality, but also of social life and above all of human existence itself. Thus, the need for a theory of interdiscipline is discovered, that not only transcends the epistemological approach, but also that of action and its ontological dimension. We propose that this expansion is achieved through a radical interdiscipline anchored in personal existence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Space, Place and Capitalism: The Literary Geographies of “The Unknown Industrial Prisoner” by Brett HeinoDavid McLaughlinSpace, Place and Capitalism: The Literary Geographies of “The Unknown Industrial Prisoner” BY BRETT HEINO Singapore: Palgrave Macmillan, 2021I would not be the first to describe Brett Heino’s new book as timely. Its publication in 2021 coincided with the fiftieth anniversary of the first publication of David Ireland’s The Unknown Industrial Prisoner (1971). (...) This experimental novel, centered on a “kaleidoscopic vision” of its characters and their lives, tells the story of a group of workers at the Puroil refinery in a fictionalized part of Sydney. In Heino’s own words, this project emerged from a desire to write about industrialization and representation in Australian fiction. Working primarily as a legal scholar and historian, this work represents his first foray into literary geography.At the heart of Heino’s argument is a question: What does literature know about space? In his pursuit of a spatially-directed reading of The Unknown Industrial Prisoner, Heino eschews work in literary geography that cultural geographers might recognize— particularly the writings of Sheila Hones, the doyenne of an emerging interdiscipline of literary geography, whose practitioners work at the interstices between literary studies and geography. Heino criticizes this interdisciplinary literary geography as being too focused on establishing the “sovereignty” or “imperialism” of fictional space at the expense of recognizing the [End Page 132] role of literature in the world. Arguably, such a stance is a misreading of the thinking within literary geography that “reading literature is essentially an experimental process in which the categorical distinction between the frames of ‘fact’ and ‘fiction’ become blurred,”1 and where the “ontological distinction between literary and non- literary spaces” is undermined.2 Neither of these statements supposes that reading literature is a practice by which the world falls away and nothing remains but the book. Instead, following Doreen Massey’s idea that space is a complicated process of events and happenings, literary geographers in this mold argue that fiction is a part of life as it happens, and reading is a constitutive practice in the co- production of space.In its place, Heino emphasizes a form of literary geographical thinking that understands literature’s role as being separate from, but intimately connected to, the actual world. His theoretical framework is multi-layered, borrowing from Marxist literary scholars, including Terry Eagleton and Fredric Jameson, and Marxist geographers, including Henri Lefebvre. In essence, however, it can be expressed neatly in the following quotation from geocritic Bertrand Westphal:Fiction does not reproduce the real, but actualises new virtualities that had remained unformulated, and then goes on to interact with the real according to the hypertextual logic of interfaces... fiction detects possibilities buried in the folds of the real, knowing that these folds have not been temporised.3I think that Heino’s rejection of what he characterizes as poststructural literary geography, of the kind represented in his analysis of Sheila Hones’s work, misses some opportunities. First, there are similarities between his conception of literary geography and those he leaves aside— not least, their shared acceptance of the productive tension that sits between literature as text and world as practical, non- representational, and exceeding narrative. Secondly, the shared aim of both approaches is to understand how “representation ‘takes place’ and precisely how texts are part of what happens.”4 This is particularly powerful in the light of Heino’s aim to understand the development and contents of literary texts in materialist terms. Despite these areas [End Page 133] of convergence, Heino’s argument that literary geography’s potential to analyze class and political structures remains untapped is well founded. This is where Heino’s contribution is at its strongest.Heino’s work is at its most convincing when he discusses the realities of “abstract space” that both permeate the spaces of The Unknown Industrial Prisoner and structure the very fabric of latter- twentieth century Australia. Running through both Heino’s critique and Ireland’s novel is an understanding “that the inherent drive of capital is towards the creation of a fragmented, homogenised and hierarchised space within which it can produce and...

In discussion about the past and the future of STS studies, insufficient attention is paid to the interdisciplinary character of this interdiscipline. After a brief characterization of the dual past (anchored on one side by Rachel Carson and on the other by Thomas Kuhn) and a glance at contemporary assessments such as the Handbook of Science and Technology Studies, this article references the past and the present of interdisciplinarity, especially as reflected in the scholarship of Julie Thompson Klein. The conclusion (...) seeks to indicate ways in which STS studies can draw on and make a special contribution to interdisciplinarity. (shrink)

Gyorgy Tamas works in the philosophy of logic, that difficult interdisciplin ary region wherein the notion of categories is both basic and subtle. To understand ways of thinking, to understand patterns of whatever is real, to recognize what is possible and to reject the nonsensical and the impossible is to comprehend the categories. This was a in thought and in fact, recurring motive of European thought from the earliest self-aware beginnings, and Tamas knows that history well, as his critical respect (...) demonstrates. Ancient, medieval, and modern thinkers appear in this book, set forth in their own words; and likewise we see that Tamas has built upon the historians and commentators, upon the pioneering historical investigation of the categories by Trendelenburg a century ago and by Bochenski in our days. Tamas has two principal goals here: to investigate the logic, which is to say the structure and the relations, of the philosophical categories; and to set forth the logic of thought which may then be based upon the critically established system of categories obtained by that investigation. Ancillary but of striking value is his style of historical relevance which enables the reader to engage in a discussion that is both analytically sharp and developmentally insightful. Furthermore, Tamas draws upon his contem porary colleagues with similar critical respect: Lukasiewicz, Quine, Patzig, Menne, Tavanets and others. (shrink)

With the publication of this inaugural issue of the internationally peer-reviewed journal Biosemiotics, our still-developing young interdiscipline marks yet another milestone in its journey towards adulthood. For this occasion, the editors of Biosemiotics have asked me to provide for those readers who may be newcomers to our field a very brief overview of the history of biosemiotics, contextualizing it within and against the larger currents of philosophical and scientific thinking from which it has emerged. To explain the origins of this (...) most twenty-first century endeavour effectively, however, will require tracing—at least to the level of a thumbnail sketch—how the ‘sign’ concept appeared, was lost, and now must be painstakingly rediscovered and refined in science. To relate this long history, this article will appear in Biosemiotics in three instalments, examining, respectively: (1) The History of the Sign Concept in Pre-Modernist Science, (2) The History of the Sign Concept in Modernist Science, and (3) The Biosemiotic Attempt to Develop a More Useful Sign Concept for Contemporary Science. In this instalment, we begin our introductory ‘stroll through the woods of sciences and signs’ by following the development of the sign concept within the context of scientific inquiry, in necessarily broad outline, from the beginnings of such inquiry in sixth century BCE, through its long development in the Middle Ages, and up unto the onset of modernity. For only within this larger historical context can our contemporary attempt to develop a naturalistic understanding of sign relations be understood. (shrink)

Philosophy of Technology Assessment: Problems of Quantification and Prediction. Technology Assessment (TA) as an interdiscipline project to assist decision-making in the area of technology politics is well-established. A critical analysis based on the constructive philosophy of science, however, uncovers several deficiencies of the philosophical foundation of TA. Especially the fundamental differences between natural and social sciences are neglected by the TA, for example by treating normative problems of decision-making with descriptive techniques of quantification and prediction. It is shown that in (...) TA the philosophical limitations for quantifications and predictions - based on elements of acting theory and a reflection on the nature of descriptive and normative propositions - are ignored. Consequently, a revision of the foundations of technology assessment is suggested. (shrink)

The greatest defender of democracy in the twentieth century could only say of it that it was a bad form of government, but better than any of the alternatives. It is thus a tribute to academic insularity that there can continue to be an academic discipline, subdiscipline, or interdiscipline devoted to "democratic theory." The major premise of "democratic theory" is that, contrary to the experience of Churchill and all other perceptive democratic statesmen, democracy can be viewed and justified without reference (...) to the circumstances in which it is found or to the available alternatives.

La interdisciplina aparece de nuevo como repetición; pero como toda repetición, diferenciada. En su primer momento se apoyó en la noción marxista de «totalidad», o en la epistemología genética de Piaget, y sus «homologías estructurales» entre disciplinas. Actualmente, tiene el tono posmoderno del abandono de la rigidez y la metodicidad: así aparece en deconstrucción o en «estudios culturales». También en versión pragmática proempresarial (Gibbons). Pero hay que advertir que las disciplinas surgieron por mutua discriminación; y que sus mutuos discursos están (...) en inconmensurabilidad (T.Kuhn). Por ello, la interdisciplina se construye, y lo hace contra el sentido común y la dispersión discursiva, estando muy lejos de una natural confluencia entre disciplinas. (shrink)

An explanation of the seeing of depth both in reality and in pictures requires a dual content theory of visual recognition. In addition, there are two necessary conditions on genuine seeing of depth-related content. First, the right kinds of dependence relations must hold between a physical picture, its content and its perceiver, and second, the perceiver must be in an appropriate, functionally defined perceptual state.
