Many writers have paid tribute to its power: Shakespeare urged his audiences to use it to create a setting; Hobbes asserted that "imagination and memory are but one thing; " for Wordsworth it was "the mightiest leveler known to moral world; " and to Baudelaire it represented "the queen of truth. " Imagination as artistic, poetic, and cultural predicate remains one of the most influential ideas in the history of Western thought. It has been simultaneously feared as a dangerous, uncontrollable (...) force, and revered as the supreme visionary power. The questions of its origins, nature, function, and effects have absorbed writers, theologians, and philosophers alike. J. M. Cocking's Imagination shows how these questions have recurred, through the ages and in various cultures. Exploring this theme, from antiquity to the Renaissance, it opens with a discussion of the treatment of imagination in the writings of Aristotle and Plato. Tracing its development in the Middle Ages, Cocking pays particular attention to the parallel tradition in Islamic thought of the period. The book pursues the concept through the theories of Dante and the neo-Platonists, concluding with the High Renaissance. (shrink)

The discussion presents a framework of concepts that is intended to account for the rationality of semantic change and variation, suggesting that each scientific concept consists of three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept’s use. I argue that in the course of history a concept can change in any of these components, and that change in the concept’s inferential role and reference can be accounted for as being rational relative (...) to the third component, the concept’s epistemic goal. This framework is illustrated and defended by application to the history of the gene concept. It is explained how the molecular gene concept grew rationally out of the classical gene concept despite a change in reference, and why the use and reference of the contemporary molecular gene concept may legitimately vary from context to context.

The philosophy of science that grew out of logical positivism construed scientific knowledge in terms of set of interconnected beliefs about the world, such as theories and observation statements. Nowadays science is also conceived of as a dynamic process based on the various practices of individual scientists and the institutional settings of science. Two features particularly influence the dynamics of scientific knowledge: epistemic standards and aims (e.g., assumptions about what issues are currently in need of scientific study and explanation). While (...) scientific beliefs are representations of the world, scientific standards and aims are epistemic values. The relevance of epistemic aims and values for belief change has been previously recognized. My paper makes a similar point for scientific concepts, both by studying how an individual concept changes (in its semantic properties) and by viewing epistemic aims and values tied to individual concepts.

Hume said that to have a memory image of some individual, x, is to perceive a ‘faint copy’ of some prior perception of x. This classical view of memory images includes three distinct claims: Images and percepts are mental entities which serve as objects for a ‘direct’ or ‘non-inferential’ perception. A memory image of some individual, x, shares numerous properties with some prior perception of x.

According to Pylyshyn, depictive representations can be explanatory only if a certain kind of first-order isomorphism exists between the mental representations and real-world displays. What about a system with second-order isomorphism (similarities between different mental representations corresponding with similarities between different real-world displays)? Such a system may help to address whether “depictive” representations contribute to the visual nature of imagery.

[First paragraph] A widespread image of science is founded upon a basic dichotomy: there are empirical facts, obtained by observation and experiment, on the one hand, and theories and explanations, obtained by reasoning, speculation and creativity, on the other. Whether scientific reasoning should take the inductive path, or the hypothetical-deductive approach, has long been a mat-ter of debate, but the basic dichotomist picture has been left untouched. And there is the concomitant idea that theories may come and go, while facts (...) form the stable, unshaken and ever growing foundation of science. This picture is often advanced in science education, for example in experimental physics courses and their textbooks. Additionally, the use of lan-guage reinforces that picture: we say that we "discover" facts (such as the cosmic micro-wave background, the variability of species), while we create, form and eventually discard theories (like the standard model of elementary particles, string theory, theories of develop-mental biology and so on). Something that has been "discovered" is attributed a different status than something that has been created and formed. (shrink)

This is the first critically evaluative study of Gaston Bachelard's philosophy of science to be written in English. Bachelard's professional reputation was based on his philosophy of science, though that aspect of his thought has tended to be neglected by his English-speaking readers. Dr Tiles concentrates here on Bachelard's critique of scientific knowledge. Bachelard emphasised discontinuities in the history of science; in particular he stressed the new ways of thinking about and investigating the world to be found in modern science. (...) This, as the author shows, is paralleled by recent debates among English-speaking philosophers about the rationality of science and the 'incommensurability' of different theories. To these problems Bachelard might be taken as offering an original solution: rather than see discontinuities as a threat to the objectivity of science, see them as products of the rational advancement of scientific knowledge. Dr Tiles sets out Bachelard's views and critically assesses them, reflecting also on the wider question of how one might assess potentially incommensurable positions in the philosophy of science as well as in science itself.

The failure of psychiatry to validate its diagnostic constructs is often attributed to the prioritizing of reliability over validity in the structure and content of the Diagnostic and Statistical Manual of Mental Disorders. Here I argue that in fact what has retarded biomedical approaches to psychopathology is unwarranted optimism about diagnostic discrimination: the assumption that our diagnostic tests group patients together in ways that allow for relevant facts about mental disorder to be discovered. I consider the Research Domain Criteria framework (...) as a new paradigm for classifying objects of psychiatric research that solves some of the challenges brought on by this assumption. (shrink)

: This paper is concerned with the claim that epistemic terms and categories are historical entities. The starting point is the observation that recent attempts at historical studies of epistemic terms fail to bridge the gap between history and philosophy proper. I examine whether, and how, it is possible to forge a closer link between historical and philosophical aspects of conceptual analysis. The paper explores possible links by analyzing aspects of the concept of error. A "pragmatic" and a "mentalist" notion (...) of error are identified in current philosophical studies of error: according to the latter, errors can be ascribed only to mental operations, according to the former, errors can also be ascribed to things and processes. The paper then draws on historical accounts of optical instruments to highlight certain presuppositions and implications of these two uses of the term. Contextual features and trans-contextual structures of the notion of error are distinguished. In conclusion, I argue that an intimate link between history and philosophy of science can be forged by an analysis ofthe development of conceptual arrangements which allows for trans- contextual structural aspects while drawing attention to the contextual epistemological and scientific conditions of their re-arrangement.

Neuroimaging and psychophysiological techniques have proved to be useful in comprehending the extent to which the visual modality is pervasive in mental imagery, and in comprehending the specificity of images generated through other sensory modalities. Although further research is needed to understand the nature of mental images, data attained by means of these techniques suggest that mental imagery requires at least two distinct processing components.

Recent research on visual mental imagery plays an important role for the study of visual hallucinations. Not only are mental images involved in various cognitive processes, but they also share many processes with visual perception. However, we rarely confuse mental images with percepts, and recent neuroimaging studies shed light on the mechanisms that are differently activated in imagery and perception.

Despite their intuitive appeal and a long philosophical history, imagery-based accounts of the imagination have fallen into disfavor in contemporary discussions. The philosophical pressure to reject such accounts seems to derive from two distinct sources. First, the fact that mental images have proved difficult to accommodate within a scientific conception of mind has led to numerous attempts to explain away their existence, and this in turn has led to attempts to explain the phenomenon of imagining without reference to such ontologically (...) dubious entities as mental images. Second, even those philosophers who accept mental images in their ontology have worried about what seem to be fairly obvious examples of imaginings that occur without imagery. In this paper, I aim to relieve both these points of philosophical pressure and, in the process, develop a new imagery-based account of the imagination: the imagery model. (shrink)

Combining philosophical and historical scholarship, the articles in this volume focus on scientific concepts, rather than theories, as units of analysis. They thereby contribute to a growing literature about the role of concepts in scientific research. The authors are particularly interested in exploring the dynamics of research; they investigate the ways in which scientists form and use concepts, rather than in what the concepts themselves represent. The fields treated range from mathematics to virology and genetics, from nuclear physics to psychology, (...) from technology to present-day neural engineering. The volume contains articles by Vassi Kindi, Miles MacLeod, Ingo Brigandt, Friedrich Steinle, Dirk Schlimm, Theodore Arabatzis, Uljana Feest, Corinne Bloch, Mieke Boon, Nancy Nersessian, and Hanne Andersen.

This paper asks (a) how new scientific objects of research are onceptualized at a point in time when little is known about them, and (b) how those conceptualizations, in turn, figure in the process of investigating the phenomena in question. Contrasting my approach with existing notions of concepts and situating it in relation to existing discussions about the epistemology of experimentation, I propose to think of concepts as research tools. I elaborate on the conception of a tool that informs my (...) account. Narrowing my focus to phenomena in cognitive neuropsychology, I then illustrate my thesis with the example of the concept of implicit memory. This account is based on an original reconstruction of the nature and function of operationism in psychology. (shrink)

In this book, Eva Brann sets out no less a task than to assess the meaning of imagination in its multifarious expressions throughout western history. The result is one of those rare achievements that will make The World of the Imagination a standard reference.

Since psychiatry remains a descriptive discipline, it is essential for its practitioners to understand how the language of psychiatry came to be formed. This important book, written by a psychiatrist-historian, traces the genesis of the descriptive categories of psychopathology and examines their interaction with the psychological and philosophical context within which they arose. The author explores particularly the language and ideas that have characterised descriptive psychopathology from the mid-nineteenth century to the present day. He presents a masterful survey of the (...) history of the main psychiatric symptoms, from the metaphysics of classical antiquity to the operational criteria of today. Tracing the evolution of concepts such as memory, consciousness, will and personality, and of symptoms ranging from catalepsy and aboulia to anxiety and self-harm, this book provides fascinating insights into the subjective nature of mental illness, and into the ideas of British, Continental and American authorities who sought to clarify and define it.

The purpose of this study is to analyze the problematic impact of technology on American health care. Although the pharmaceutical industry's use of technology has produced beneficial results, at times the industry seems to overlook the unintended consequences involved. This study also examines the pharmaceutical industry's attempts to influence the physician's prescribing decisions as well as the patient's desire to get well as soon as possible. It analyzes the FDA's role in approving drugs, in monitoring the post-approval process, and in (...) overseeing the industry's technological excesses. While the industry has the admirable goal of trying to relieve or eradicate illness, a few firms regularly engage in questionable behavior as they strive to increase their profitability. In addition to using ethically suspect marketing techniques, some firms suppress unfavorable research. In sum, it is clear that the drug industry needs to engage in deeper ethical reflection. ^.
