How do novel scientific concepts arise? In Creating Scientific Concepts, Nancy Nersessian seeks to answer this central but virtually unasked question in the problem of conceptual change. She argues that the popular image of novel concepts and profound insight bursting forth in a blinding flash of inspiration is mistaken. Instead, novel concepts are shown to arise out of the interplay of three factors: an attempt to solve specific problems; the use of conceptual, analytical, and material resources provided by the (...) cognitive-social-cultural context of the problem; and dynamic processes of reasoning that extend ordinary cognition. Focusing on the third factor, Nersessian draws on cognitive science research and historical accounts of scientific practices to show how scientific and ordinary cognition lie on a continuum, and how problem-solving practices in one illuminate practices in the other.

Ault, Nancy J Spiritual direction is at risk in a society which is turning increasingly to personal feelings to validate experience and justify decision making. An appeal to feelings and emotions enables marketers to sell religion and spirituality as consumer products. As a product among many, the wider contexts of religion and spirituality may fade from consciousness and be lost. In such a 'pick and mix' culture, as well as losing sight of the embodied nature of understanding, what may (...) happen is a slow drifting apart of thinking, feelings and action. The cost of such a separation is high. Feelings may disintegrate into sentimentalism, thinking sink into legalism and action become uninformed reaction. Hence, practices which facilitate the intentional integration of mind, heart and behaviour can provide an essential counterbalance to the contemporary forces engendering separation. (shrink)

Excitation at widely dispersed loci in the cerebral cortex may represent a neural correlate of consciousness. Accordingly, each unique combination of excited neurons would determine the content of a conscious moment. This conceptualization would be strengthened if we could identify what orchestrates the various combinations of excited neurons. In the present paper, cholinergic afferents to the cerebral cortex are hypothesized to enhance activity at specific cortical circuits and determine the content of a conscious moment by activating certain combinations of postsynaptic (...) sites in select cortical modules. It is proposed that these selections are enabled by learning-related restructuring that simultaneously adjusts the cytoskeletal matrix at specific constellations of postsynaptic sites giving all a similar geometry. The underlying mechanism of conscious awareness hypothetically involves cholinergic mediation of linkages between microtubules and microtubule-associated protein-2 . The first reason for proposing this mechanism is that previous studies indicate cognitive-related changes in MAP-2 occur in cholinoceptive cells within discrete cortical modules. These cortical modules are found throughout the cerebral cortex, measure 1–2 mm2, and contain approximately 103–104cholinoceptive cells that are enriched with MAP-2. The subsectors of the hippocampus may function similarly to cortical modules. The second reason for proposing the current mechanism is that the MAP-2 rich cells throughout the cerebral cortex correspond almost exactly with the cortical cells containing muscarinic receptors. Many of these cholinoceptive, MAP-2 rich cells are large pyramidal cell types, but some are also small pyramidal cells and nonpyramidal types. The third reason for proposing the current mechanism is that cholinergic afferents are module-specific; cholinergic axons terminate wholly within individual cortical modules. The cholinergic afferents may be unique in this regard. Finally, the tapering apical dendrites of pyramidal cells are proposed as primary sites for cholinergic mediation of linkages between MAP-2 and microtubules because especially high amounts of MAP-2 are found here. Also, the possibility is raised that muscarinic actions on MAP-2 could modulate microtubular coherence and self-collapse, phenomena that have been suggested to underlie consciousness. (shrink)

Research on women's preponderance among animal rights advocates explains it exclusively as a product of women's socialization, emphasizing a relational orientation of care and nurturing that extends to animals. The authors propose a more structural explanation: Women's experiences with structural oppression make them more disposed to egalitarian ideology, which creates concern for animal rights. Using data from a 1993 national sample, the authors find that an egalitarian gender ideology is a key difference in women's and men's routes to animal rights (...) advocacy: It differentiates those more likely to endorse animal rights among women but not among men. Neither this ideology nor other variables in the analysis, however, account for women's greater overall support of animal rights in the combined sample. Reasons for this latter finding are explored.

This paper examines the nature of model-based reasoning in the interplay between theory and experiment in the context of biomedical engineering research laboratories, where problem solving involves using physical models. These "model systems" are sites of experimentation where in vitro models are used to screen, control, and simulate specific aspects of in vivo phenomena. As with all models, simulation devices are idealized representations, but they are also systems themselves, possessing engineering constraints. Drawing on research in contemporary cognitive science that construes (...) cognition as occurring in a complex distributed system comprising people and artifacts, I argue that reasoning with model systems is a constraint satisfaction process involving co-construction, manipulation, and revision of mental and physical models.

In Gender, Class, and Freedom in Modern Political Theory, Nancy Hirschmann demonstrates not merely that modern theories of freedom are susceptible to gender and class analysis but that they must be analyzed in terms of gender and class in order to be understood at all. Through rigorous close readings of major and minor works of Hobbes, Locke, Rousseau, Kant, and Mill, Hirschmann establishes and examines the gender and class foundations of the modern understanding of freedom. Building on a social (...) constructivist model of freedom that she developed in her award-winning book The Subject of Liberty: Toward a Feminist Theory of Freedom, she makes in her new book another original and important contribution to political and feminist theory. Despite the prominence of "state of nature" ideas in modern political theory, Hirschmann argues, theories of freedom actually advance a social constructivist understanding of humanity. By rereading "human nature" in light of this insight, Hirschmann uncovers theories of freedom that are both more historically accurate and more relevant to contemporary politics. Pigeonholing canonical theorists as proponents of either "positive" or "negative" liberty is historically inaccurate, she demonstrates, because theorists deploy both conceptions of freedom simultaneously throughout their work.

A theoretical approach relying on quantum computation in microtubules within neurons can potentially resolve the enigmatic features of visual consciousness, but raises other questions. For example, how can delicate quantum states, which in the technological realm demand extreme cold and isolation to avoid environmental ‘decoherence’, manage to survive in the warm, wet brain? And if such states could survive within neuronal cell interiors, how could quantum states grow to encompass the whole brain? We present a physiological model for visual consciousness (...) that can accommodate brain-wide quantum computation according to the Penrose–Hameroff ‘Orch OR’ model. In this view, visual consciousness occurs as a series of several-hundred-millisecond epochs, each comprising ‘crescendo sequences’ of quantum computations occurring at ∼40 Hz. (shrink)

Thought experiments have played a prominent role in numerous cases of conceptual change in science. I propose that research in cognitive psychology into the role of mental modeling in narrative comprehension can illuminate how and why thought experiments work. In thought experimenting a scientist constructs and manipulates a mental simulation of the experimental situation. During this process, she makes use of inferencing mechanisms, existing representations, and general world knowledge to make realistic transformations from one possible physical state to the next. (...) The simulation reveals the impossibility of integrating multiple constraints drawn from existing representations and the world and pinpoints the locus of the required conceptual reform.

In this paper, the authors describe an aspect of a program of research around grief and clinical practice. The first phase of the study involves examination of experiences of grief with attention to troublesome or problematic beliefs that fuel the extent of suffering in the bereaved. The data, obtained from a review of videotaped clinical interviews with families seen in the Family Nursing Unit at the University of Calgary, were analyzed according to philosophical hermeneutic tradition. Findings suggest that grief is (...) an experience that is ongoing, that changes in nature over time, but that involves a continuing relationship with the deceased; it is a graceful, periodic, deliberate walk backwards while keeping a sure foot in living forward.

The book examines the emerging approach of using qualitative methods, such as interviews and field observations, in the philosophy of science. Qualitative methods are gaining popularity among philosophers of science as more and more scholars are resorting to empirical work in their study of scientific practices. At the same time, the results produced through empirical work are quite different from those gained through the kind of introspective conceptual analysis more typical of philosophy. This volume explores the benefits and challenges of (...) an empirical philosophy of science and addresses questions such as: What do philosophers gain from empirical work? How can empirical research help to develop philosophical concepts? How do we integrate philosophical frameworks and empirical research? What constraints do we accept when choosing an empirical approach? What constraints does a pronounced theoretical focus impose on empirical work? Nine experts discuss their thoughts and empirical results in the chapters of this book with the aim of providing readers with an answer to these questions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.1 (2002) 216-223 [Access article in PDF] Notes and Fragments Genre Fiction and "The Origin of the Work of Art" Nancy J. Holland I FIRST, A CONFESSION. Like, I suspect, many of my readers, I am an unpublished fiction writer. Unlike most of the closet fiction writers in academia, however, I write genre fiction. The question that immediately follows is how that writing is related (...) to the intellectual work I do in philosophy.This question, of course, is open to a broad range of answers, from the possibility that the two aren't related at all, to potential Freudian answers it might take years of therapy to unearth. Teaching informs one's life, however, as much as the reverse, and in teaching Martin Heidegger's "The Origin of the Work of Art" to my Metaphysics class last year, I began to understand at least one dimension of the appeal that writing genre fiction has for me as a philosopher.But first, let me explain what I mean by genre fiction. In what follows, I will be referring primarily to four forms of genre fiction that have clear roots in the nineteenth century in Western Europe and North America: two gender-segregated genres, the western and the romance, and two gender-marked genres, science fiction and detective novels. I will be comparing these to two other forms of "popular culture" that also developed in the nineteenth century and have, I would argue, similar relationships to the older, more "legitimate," more elite art forms which they closely resemble: photography 1 and popular music, [End Page 216] especially those forms of popular music such as ragtime, blues, jazz, and rock that are informed by the African-American experience in the United States. 2These "low brow" art forms all appear to have arisen out of the growth of the middle class in developing parts of the world during the nineteenth century and the correlative confluence of greater leisure, greater aggregate prosperity, and higher levels of education across a broader spectrum of society. Further, these art forms all combine the surface appearance of their respective "high brow" correlate arts with the reassurance of repetition that is the cornerstone of the folk arts with which they are also correlated. Each of these forms of popular culture balances itself, then, between a demand for more and more "works of art" (and/or class aspirations based on the appearance of such) and a demand for the familiar in a rapidly changing, materially challenging world.Thus, photography gives us a frozen and thereby purified visual reality, an icon of memory to which we can return at will. The truth it reveals is most often starker than that of folk painting and portraiture, but also gives the appearance of being free from the subjectivity of the artist. Great iconic photographs such as the kiss on V-E day, I have heard it said, become more real than the reality they encapsulated.Popular music similarly combines often amazing musical complexity (which is not unknown, although rarer, in western folk music) with the reassurance of a form that not only repeats itself within a song, but also between songs of the same genre. Thus, blues can be recognized by both the minor chords in its melodies and the characteristic rhyme pattern of its lyrics. Moreover, most western popular music, even to some extent free-form jazz, has a familiar and reassuring beginning-middle-end structure, both melodically and dynamically, that locates a listener immediately within the song's "story-arc." 3This same beginning-middle-end structure is one clear hallmark of genre fiction. Another is repetition. We all immediately know the plot of a detective novel or science fiction adventure: where it will begin, what the key stages of the story will be, and how it will end—not just happily, but with a specific form of reassuring outcome, be it the victory of well-intentioned intelligence over cunning evil or humanity's ability to survive even the most alien (and so most familiar) of threats.

Designing, building, and experimenting with physical simulation models are central problem‐solving practices in the engineering sciences. Model‐based simulation is an epistemic activity that includes exploration, generation and testing of hypotheses, explanation, and inference. This paper argues that to interpret and understand how these simulation models function in creating knowledge and technologies requires construing problem solving as accomplished by a researcher–artifact system. It draws on and further develops the framework of “distributed cognition” to interpret data collected in ethnographic and cognitive‐historical studies (...) of two biomedical engineering research laboratories, and articulates the notion of distributed model‐based cognition to answer the question posed in the title.

There is substantial evidence that traditional instructional methods have not been successful in helping students to restructure their commonsense conceptions and learn the conceptual structures of scientific theories. This paper argues that the nature of the changes and the kinds of reasoning required in a major conceptual restructuring of a representation of a domain are fundamentally the same in the discovery and in the learning processes. Understanding conceptual change as it occurs in science and in learning science will require the (...) development of a common cognitive model of conceptual change. The historical construction of an inertial representation of motion is examined and the potential instructional implications of the case are explored. (shrink)

A cognitive ethnography of how bioengineering scientists create innovative modeling methods. In this first full-scale, long-term cognitive ethnography by a philosopher of science, Nancy J. Nersessian offers an account of how scientists at the interdisciplinary frontiers of bioengineering create novel problem-solving methods. Bioengineering scientists model complex dynamical biological systems using concepts, methods, materials, and other resources drawn primarily from engineering. They aim to understand these systems sufficiently to control or intervene in them. What Nersessian examines here is how cutting-edge (...) bioengineering scientists integrate the cognitive, social, material, and cultural dimensions of practice. Her findings and conclusions have broad implications for researchers in philosophy, science studies, cognitive science, and interdisciplinary studies, as well as scientists, educators, policy makers, and funding agencies. In studying the epistemic practices of scientists, Nersessian pushes the boundaries of the philosophy of science and cognitive science into areas not ventured before. She recounts a decades-long, wide-ranging, and richly detailed investigation of the innovative interdisciplinary modeling practices of bioengineering researchers in four university laboratories. She argues and demonstrates that the methods of cognitive ethnography and qualitative data analysis, placed in the framework of distributed cognition, provide the tools for a philosophical analysis of how scientific discoveries arise from complex systems in which the cognitive, social, material, and cultural dimensions of problem-solving are integrated into the epistemic practices of scientists. Specifically, she looks at how interdisciplinary environments shape problem-solving. Although Nersessian’s case material is drawn from the bioengineering sciences, her analytic framework and methodological approach are directly applicable to scientific research in a broader, more general sense, as well.

Building computational models of engineered exemplars, or prototypes, is a common practice in the bioengineering sciences. Computational models in this domain are often built in a patchwork fashion, drawing on data and bits of theory from many different domains, and in tandem with actual physical models, as the key objective is to engineer these prototypes of natural phenomena. Interestingly, such patchy model building, often combined with visualizations, whose format is open to a wide range of choice, leads to the discovery (...) of new concepts and control structures. Two key questions are raised by this practice: how could discoveries arise from building external representations for which there is wide latitude in choice of the components from which they are built, and thus can be considered significantly arbitrary, and how could such discoveries allow engineering a real-world prototype system. To examine these questions, we present two case studies of discoveries that emerged from the building of such computational models in the bioengineering sciences. We then develop a process model that accounts for the discovery and transfer problems raised by both these cases, focusing on the process of building the model. Specifically, to account for the discovery problem, we propose that the process of building such models gradually leads to a close coupling between the modeler’s internal processes and the external dynamic model. To account for the transfer problem, we propose that the process of building the model leads to the creation of an enactive model that is generic, which closely enacts, and thus reveals, the way the system-level behavior of the engineered prototype emerges in time through the interaction of its parts. This enactive replication process leads to the model and the prototype forming a new class, which allows concepts and control structures developed for the computational model to be transfered to the real-world prototype. We argue that this account requires rethinking correspondence in engineering sciences as a plastic and enactive relation. A closer focus on the process of building models is required to develop a general account of this emerging approach to discovery. (shrink)

Trust in the nurse—patient relationship is maintained not by how professionals perceive their actions but rather by how the public perceives them. However, little is known about the public's view of nurses and other health care professionals who participate in pharmaceutical marketing. Our study describes public perceptions of health care providers' role in pharmaceutical marketing and compares their responses with those of a random sample of licensed family nurse practitioners. The family nurse practitioners perceived their participation in marketing activities as (...) significantly more ethically appropriate than did the public responders. Further research is warranted before conclusions can be drawn, but these early findings suggest that nurse practitioners should consider a conservative approach to participating in pharmaceutical marketing.

Robert Sparrow has recently claimed that unless there are reasons to think the sexed nature of human beings is normatively significant, current trends in bioethical reasoning force the conclusion that “we may do well to move toward a ‘post sex’ humanity” (American Journal of Bioethics 10: 7 (2010)). This commentary uses basic methodological principles from feminist ethics to argue that he has, in fact, given no reasons to think that a 'post sex' humanity is any more valuable than gender diverse (...) one, and no reason to think that sexual dimorphism has normative significance as a brute biological fact.

Character structures underlie everyone’s personality. When rigidly defended, they limit us; yet as they become more flexible, they can reveal sources of animation, renewal and authenticity. _The Matrix and Meaning of Character_ guides the reader into an awareness of the archetypal depths that underlie character structures, presenting an original developmental model in which current analytic theories are synthesised. The authors examine nine character structures, animating them with fairy tales, mythic images and case material, creating a bridge between the traditional language (...) of psychopathology and the universal realm of image and symbol. This book will appeal to all analytical psychologists, psychoanalysts and psychotherapists who want to strengthen their clinical expertise. It will help clinicians to extend their clinical insights beyond a strictly behavioural, medical or cognitive approach, revealing the potential of the human spirit. (shrink)

Cases where analogy has played a significant role in the formation of a new scientific concept are well-documented. Yet, how is it that genuinely new representations can be constructed from existing representations? It is argued that the process of ‘generic modeling’ enables abstraction of features common to both the domain of the source of the analogy and of the target phenomena. The analysis focuses on James Clerk Maxwell's construction of the electromagnetic field concept. The mathematical representation Maxwell constructed turned out (...) to be a system of abstract laws that when applied to electromagnetic systems yield laws of a dynamical system that will not map back onto the mechanicals domains used in their construction.

Giere's assessment is that the cognitive sciences, especially cognitive psychology, have much to offer the philosophy of science as it attempts to develop theories of the growth, development, and change of scientific knowledge as human activities. Margolis produces a model of scientific change by drawing from recent work in the cognitive sciences and attempts to show how this model explains salient cases of conceptual change. While agreeing with Giere's assessment, I argue that Margolis provides the wrong model both for scientific (...) change and for how the interaction between cognitive science and philosophy of science should proceed.

The sexual division of labor and the social and economic value of women’s work in the home has been a problem that scholars have struggled with at least since the advent of the “second wave” women’s movement, but it has never entered into the primary discourses of political science. This paper argues that John Stuart Mill’s Political Economy provides innovative and useful arguments that address this thorny problem. Productive labor is essential to Mill’s conception of property, and property was vital (...) to women’s independence in Mill’s view. Yet since Mill thought most women would choose the “career” of wife and mother rather than working for wages, then granting that work productive status would provide a radical and inventive foundation for women’s equality. Mill, however, is ambiguous about the productive status of domestic labor, and is thereby representative of a crucial failure in political economic thought, as well as in egalitarian liberal thought on gender. But because Mill at the same time develops a conception of production that goes well beyond the narrow limits offered by other prominent political economists, he offers contemporary political scientists and theorists a way to rethink the relationship of reproductive to productive labor, the requirements for gender equality, and the accepted categories of political economy.

Feminist scholars have been remaking the landscape in political theory, and in this important book some of the most important feminist political theorists provide reconstructions of those concepts most central to the tradition of political philosophy. The goal is nothing less than the construction of a blueprint for a positive feminist theory.Many of these papers are completely new; others are extensions of important earlier work; two are reprints of classic papers. The result is a progress report on the continuing feminist (...) project to re-envision traditional political theory. As such, it constitutes essential reading not only for feminist thinkers but also for traditional philosophers and political theorists, who will need to come to terms with these contemporary critiques and re-readings.

Concept formation in science is a reasoned process, commensurate with ordinary problem-solving processes. An account of how analogical reasoning and reasoning from imagistic representations generate new scientific concepts is presented. The account derives from case studies of concept formation in science and from computational theories of analogical problem solving in cognitive science. Concept formation by analogy is seen to be a process of increasing abstraction from existing conceptual structures.

In this commentary, arguments are made for a dendritic code being preferable to a temporal synaptic code as a model of conscious experience. A temporal firing pattern is a product of an ongoing neural computation; hence, it is based on a neural algorithm and an algorithm may not provide the most suitable model for conscious experience. Reiteration of a temporal firing code as suggested in a preceding article (Helekar, 1999) does not necessarily improve the situation. The alternative model presented here (...) is that certain synaptic activity patterns, possibly those possessing universal features as suggested by Helekar, can become encoded in the dendritic structure. Following dendritic encoding, quantum phenomena in those specific dendrite sets could illuminate the static image of that encoded synaptic activity. It is the activation of the static image that would be equivalent to conscious experience; thus, conscious awareness would not be directly affiliated with synaptic activity. This dendrite encoding model may go farther than other models to explain the gestalt nature of consciousness, insofar as quantum entanglement could produce an interconnectedness between specific sets of dendrites-an interconnectedness that need not be based on neural computation or neural connections.
