Visual percepts frequently appear chromatically rich, yet their paucity in reportable information has led to widely accepted minimalist models of vision. The discrepancy may be resolved by positing that the richness of natural scenes is reflected in phenomenal consciousness but not in detail in the phenomenal judgments upon which reports about qualia are based. Conceptual awareness (including phenomenal judgments) arises from neural mechanisms that categorize objects, and also from mechanisms that conceptually characterize textural properties of pre-categorically segmented regions in the (...) visual field. Experimental evidence suggests that complex images instigate the generation of so-called ensemble phenomenal judgments. These involve concepts that categorize global attributes of segmented areas but carry no information pertaining to details. It is then argued that there are cogent reasons for believing that phenomenal percepts (i.e. qualia) arising from chromatically complex stimuli cohere in this ensemble sense with both the stimulus and with the resulting ensemble phenomenal judgments. Thus, spatially detailed retinal images are deemed to yield correspondingly detailed phenomenal experiences that are in turn conceptually apprehended via a relatively small number of ensemble phenomenal judgments. Lastly, it is suggested that the bridge locus for chromatically rich phenomenal experiences is most plausibly located early in the cortical visual pathway. (shrink)

Higher-order representation (HOR) theories posit that the contents of lower-order brain states enter consciousness when tracked by a higher-order brain state. The nature of higher-order monitoring was examined in light of current scientific knowledge, primarily in experimental perceptual psychology. The most plausible candidate for higher-order state was found to be conceptual short-term memory (CSTM), a buffer memory intimately connected with a semantic engine operating in the medium of the language of thought (LOT). This combination meets many of the requirements of (...) HOR theories, although falling short in some significant respects, most notably the inability of higher- order states to represent more than a small fraction of the information contained in primary states, especially in vision. A possible way round this obstacle is suggested, involving the representation of visual detail by means of ensemble concepts. (shrink)

It has been suggested that the core neural bases for visual phenomenal consciousness and for access consciousness are located in anatomically separate regions. If this is correct, and if, as Block suggests, the core neural substrate of visual phenomenality is located early in the visual cortex where detailed chromatic information is available, then it would be reasonable to infer that our intuitions of chromatically rich visual phenomenality are plausible. It is furthermore suggested that during perception cognitive access to this chromatic (...) cornucopia is mediated through mereologically superordinate concepts that regionally characterize both semantic and quantitative integrated properties within complex visual percepts. Such concepts contain much less information than do the particulars that they characterize, implying that the information represented in phenomenal consciousness greatly exceeds the information in the accompanying access consciousness.

_ Source: _Volume 29, Issue 1, pp 9 - 38 Hobbes tried to develop a strict version of the mechanical philosophy, in which all physical phenomena were explained only in terms of bodies in motion, and the only forces allowed were forces of collision or impact. This ambition puts Hobbes into a select group of original thinkers, alongside Galileo, Isaac Beeckman, and Descartes. No other early modern thinkers developed a strict version of the mechanical philosophy. Natural philosophies relying solely on (...) bodies in motion require a concept of inertial motion. Beeckman and Descartes assumed rectilinear motions were rectilinear, but Galileo adopted a theory which has been referred to as circular inertia. Hobbes’s natural philosophy depended to a large extent on what he called “simple circular motions.” In this paper, I argue that Hobbes’s simple circular motions derived from Galileo’s belief in circular inertia. The paper opens with a section outlining Galileo’s concept, the following section shows how Hobbes’s physics depended upon circular motions, which are held to continue indefinitely. A third section shows the difficulty Hobbes had in maintaining a strictly mechanistic philosophy, and the conclusion offers some speculations as to why Galileo’s circular inertia was never entertained as a serious rival to rectilinear inertia, except by Hobbes.

Isaac Beeckman was a master craftsman from the Zeeland town Middelburg who studied to become schoolmaster in the Holland towns of Rotterdam and Dordrecht. He was a strict Calvinist and a tireless observer and contemplator of natural phenomena. Foremost, he was the first mechanical philosopher in Europe who played a key role in the intellectual development of René Descartes and inspired pioneers of mechanistic thinking Marin Mersenne and Pierre Gassendi . We know this because Beeckman kept a journal throughout his (...) life in which he recorded his observations and ideas. The journal is a treasure trove of early modern knowing. Beeckman had a keen eye for the world around him and responded to what he saw, as well as the reflections of others, with a highly original mind. The journal was discovered in 1905 by Cornelis de Waard , who subsequently edited and published it between 1939 and 1953 . Although some acquainta .. (shrink)

Rene Descartes's motto challenges his would-be historians: "He lives well who hides well." He hid even in the Discourse on Method, where he professed to recount the story of his "entire life, " but said almost nothing about his childhood and youth. He mentioned neither family nor friends, and he boasted a total freedom from irrational passions. In the Discourse, which presented a new way of achieving certain truth through mathematical reason, Descartes stressed just one event, a day of thinking (...) at the beginning of winter, 1619. Tucked away in an unpublished notebook, however, Descartes also left the Olympica, which documented the wildly irrational dreams he had the night of November 10, 1619, and gave his own enthusiastic interpretations. Embarrassed scholars have tried to reason away this record and even the dreams themselves. Adapting clinical methods to historical research, John Cole offers the first systematic interpretation of the Olympian dreams. He argues that they expressed and masked Descartes's unresolved conflicts: his guilt at having rejected the law career for which he had been trained and which his lawyer father had wanted him to pursue, and his shame over early failures to satisfy the high expectations of his friend and mentor, Isaac Beeckman. Cole shows us how a critical historian can make sense of such irrational material and lets us see the creation of an egocentric and rationalist philosophy. (shrink)

One of the chief concerns of the young Descartes was with what he, and others, termed “physico-mathematics”. This signalled a questioning of the Scholastic Aristotelian view of the mixed mathematical sciences as subordinate to natural philosophy, non explanatory, and merely instrumental. Somehow, the mixed mathematical disciplines were now to become intimately related to natural philosophical issues of matter and cause. That is, they were to become more ’physicalised’, more closely intertwined with natural philosophising, regardless of which species of natural philosophy (...) one advocated. A curious, short-lived yet portentous epistemological conceit lay at the core of Descartes’ physico-mathematics—the belief that solid geometrical results in the mixed mathematical sciences literally offered windows into the realm of natural philosophical causation—that in such cases one could literally “see the causes”. Optics took pride of place within Descartes’ physico-mathematics project, because he believed it offered unique possibilities for the successful vision of causes. This paper traces Descartes’ early physico-mathematical program in optics, its origins, pitfalls and its successes, which were crucial in providing Descartes resources for his later work in systematic natural philosophy. It explores how Descartes exploited his discovery of the law of refraction of light—an achievement well within the bounds of traditional mixed mathematical optics—in order to derive—in the manner of physico-mathematics—causal knowledge about light, and indeed insight about the principles of a “dynamics” that would provide the laws of corpuscular motion and tendency to motion in his natural philosophical system.

In the early decades of the seventeenth century, various attempts were made to develop a dynamical vocabulary on the basis of work in the practical mathematical disciplines, particularly statics and hydrostatics. The paper contrasts the Mechanica and Archimedean approaches, and within the latter compares conceptions of statics and hydrostatics and their possible extensions in the work of Stevin, Beeckman and Descartes. Descartes’ approach to hydrostatics, a discussion of which forms the core of the paper, is shown to be quite different (...) from that of his contemporaries, above all in its attempt to provide a natural-philosophical grounding for hydrostatics while at the same time using it to develop a range of concepts, approaches and ways of thinking through problems that would shape Descartes’ mature work in optics and cosmology.Author Keywords: Scientific revolution; René Descartes; Isaac Beeckman; Simon Stevin; History of mechanics; History of statics; History of optics.

According to the cognitive penetrability hypothesis, our beliefs, desires, and possibly our emotions literally affect how we see the world. This book elucidates the nature of the cognitive penetrability and impenetrability hypotheses, assesses their plausibility, and explores their philosophical consequences. It connects the topic's multiple strands (the psychological findings, computationalist background, epistemological consequences of cognitive architecture, and recent philosophical developments) at a time when the outcome of many philosophical debates depends on knowing whether and how cognitive states can influence perception. (...) All sixteen chapters were written especially for the book. The first chapters provide methodological and conceptual clarification of the topic and give an account of the relations between penetrability, encapsulation, modularity, and cross-modal interactions in perception. Assessments of psychological and neuroscientific evidence for cognitive penetration are given by several chapters. Most of the contributions analyse the impact of cognitive penetrability and impenetrability on specific philosophical topics: high-level perceptual contents, the epistemological consequences of penetration, nonconceptual content, the phenomenology of late perception, metacognitive feelings, and action. The book includes a comprehensive introduction which explains the history of the debate, its key technical concepts (informational encapsulation, early and late vision, the perception-cognition distinction, hard-wired perceptual processing, perceptual learning, theory-ladenness), and the debate's relevance to current topics in the philosophy of mind and perception, epistemology, and philosophy of psychology.

In 1984, John W. Yolton published Perceptual Acquaintance from Descartes to Reid. His most recent book builds on that seminal work and greatly extends its relevance to issues in current philosophical debate. Perception and Reality examines the theories of perception implicit in the work of seventeenth- and eighteenth-century philosophers which centered on the question: How is knowledge of the body possible? That question raises issues of mind-body relation, the way that mentality links with physicality, and the nature of the (...) known world. In contrast to commonsense realism, which suggests that the world is as it appears to be, a more complex theory developed throughout this period. Yolton traces its evolution from Descartes to Kant, via Arnauld, Malebranche, Locke, Berkeley, and Hume. Yolton explains that the new theory postulated two interactive relations between perceivers and the physical world, one physical and causal, the other cognitive. An understanding of this double relation is important for an accurate construction of the history of philosophy. It is also important for contemporary thought because it suggests a way to account for representation (cognitivity) and realism at the same time. (shrink)

This book provides an intellectual biography of Max Horkheimer during the early and middle phases of his life and analyzes his model of early Critical Theory.

This book addresses one of the fundamental topics in philosophy: the relation between appearance and reality. John Yolton draws on a rich combination of historical and contemporary material, ranging from the early modern period to present-day debates, to examine this central philosophical preoccupation, which he presents in terms of distinctions between phenomena and causes, causes and meaning, and persons and man. He explores in detail how Locke, Berkeley and Hume talk of appearances and their relation to reality, and offers (...) illuminating connections and comparisons with the work of contemporary philosophers such as Paul Churchland and John McDowell. He concludes by offering his own proposal for a 'realism of appearances', which incorporates elements of both Humean and Kantian thinking. His important study will be of interest to a wide range of readers in the history of philosophy, the history of ideas, and contemporary philosophy of mind, epistemology and metaphysics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Descartes’ Meditations: Background Source Materials ed. by Roger Ariew, John Cottingham, and Tom SorellRichard A. WatsonRoger Ariew, John Cottingham, and Tom Sorell, editors. Descartes’ Meditations: Background Source Materials. Cambridge: Cambridge University Press, 1998. Pp. xviii + 170. Cloth, $54.95. Paper, $18.95.This volume includes primarily source materials from authors who were contemporary to Descartes’s composition of the Meditations. Thus there are no selections from Augustine, Aquinas, and (...) Montaigne, for example, who were more influential on the Meditations than some of the authors excerpted. Of course their influence is already amply documented by such scholars as Gilson and Gouhier. Probably the most important source included is Suárez, whose role is championed by Jean-Luc Marion in several works. Readers should look for the forthcoming Index Augustino-Cartèsian: Textes et Commentaire by Zbigniew Janowski (Paris: J. Vrin) for a startling challenge to the view that Descartes is Suárezian.In the volume under review, Eustachius a Sancto Paulo is of special interest because Descartes thought of refuting him item by item (but decided exposition of his own view would be adequate). In his youth Descartes had a definite interest in Petrus Ramus, although Beeckman told him his method consisted of tired old tricks. Francisco Sanches and Pierre Charron are important for their expositions of sceptical arguments and attitudes. Christopher Clavius is Descartes’s direct predecessor in mathematical analysis, and none of Descartes’s protests that he never read the man has convinced anyone. Scipion Dupleix is a fine example of how the Old Philosophy appeared to the New Philosophers, and Marin Mersenne, of course, compiled material on every subject Descartes ever had an interest in. Pierre Gassendi exercised Descartes’s ire more than any other commentator on the Meditations, and Descartes again probably read Gassendi’s continuing criticisms even though he claimed he wouldn’t. [End Page 366]Of special interest is Jean de Silhon, an old friend of Descartes’s who published a book containing a proto-cogito three years before the Meditations appeared. François de la Mothe le Vayer represents the libertine strain many detect in Descartes’s writings, while Jean-Baptiste Morin provides fodder for those who detect Descartes’s piety, although Descartes asserts that the man is an idiot for defending the immobility of the earth. Finally, Charles Sorel provides an example of the deductive mode of exposition in a text that shows that the notion of a unified science was more than Cartesian. One contemporary who was left out and should have been included was the Augustinian Guillaume Gibieuf.But overall, this is an interesting and useful collection of works Descartes doubtless knew.

Nowadays, science is treated an instrument of policy, serving the material interests of government and commerce. Traditionally, however, it also has important non-instrumental social functions, such as the creation of critical scenarios and world pictures, the stimulation of rational attitudes, and the production of enlightened practitioners and independent experts. The transition from academic to ‘post-academic’ science threatens the performance of these functions, which are inconsistent with strictly instrumental modes of knowledge production. In particular, expert objectivity is negated by entanglement with (...) political and commercial interests. We cannot go back to the old academic model for science, but need to consider how to maintain its vital non-instrumental roles. (shrink)

Digital pictures can be type-identical in respect of colours, shapes and sizes (allographic), but they are not tokens of notational systems, because the types under which they are identical have vague limits and do not meet the requirements for notational characters. Digital display devices are designed to instantiate only limited ranges of objective properties (light intensities, sizes and shapes). Those ranges keep differences in objective magnitudes below sensory discrimination thresholds, and thus define objective conditions sufficient, but not necessary, for the (...) phenomenal type-identity of pictures. The fact that digital pictures are types shows that pictures are not necessarily autographic. Moreover, the reasons why digital pictures are allographic (essentially, the consistent manipulation of sub-phenomenal information) could in principle also be made to apply to non-digital pictures.

This volume attempts to give a short account of Herbert Spencer's life, an appreciation of his characteristics, and a statement of some of the services he rendered to science. Prominence has been given to his Autobiography, to his Principles of Biology, and to his position as a cosmic evolutionist; but little has been said of his psychology and sociology, which require another volume, or of his ethics and politics, or of his agnosticism-the whetstone of so many critics. Our appreciation of (...) Spencer's services is therefore partial, but it may not for that reason fail in its chief aim, that of illustrating the working of one of the most scientific minds that ever lived, -whose excess of science was almost unscientific.-.

Despite recurring efforts, a gap exists across a variety of contexts between the protection of patients' safety in theory and in practice. This timely Research Handbook highlights these critical issues and suggests both legal and policy changes are necessary to better protect patients' safety. Multidisciplinary in nature, this Research Handbook features contributions from eminent academics, policy makers and medical practitioners from the Global North and South, discussing the essential facets concerning patient safety and the law. It highlights how the role (...) of legislation and case law has the potential to influence, both positively and negatively, medical practice and the quality of care. Chapters explore patient safety and the global health agenda; physiotherapy; 'non-therapeutic' clinical research with children; patient safety awareness in healthcare education; and the increasing use of robotics and artificial intelligence in healthcare. Outlining a wide range of international perspectives on patient safety and the law, this Research Handbook will appeal to academics and researchers specialising in health and medical law, human rights and healthcare regulation. It will also serve as a valuable resource for legal and medical practitioners alike, as well as clinicians and professionals working in healthcare governance. (shrink)

The presence of a kinship link between nuclear families is the strongest predictor of interhousehold sharing in an indigenous, predominantly Dolgan food-sharing network in northern Russia. Attributes such as the summed number of hunters in paired households also account for much of the variation in sharing between nuclear families. Differences in the number of hunters in partner households, as well as proximity and producer/consumer ratios of households, were investigated with regard to cost-benefit models. The subset of households involved in reciprocal (...) meal sharing is 26 of 84 household host-guest pairs. The frequency of reciprocal meal sharing between families in this subset is positively correlated with average household relatedness. The evolution of cooperation through clustering may illuminate the relationship between kinship and reciprocity at this most intimate level of food sharing. (shrink)

Research scientists are trained to produce specialised bricks of knowledge, but not to look at the whole building. Increasing public concern about the social role of science is forcing science students to think about what they are actually learning to do. What sort of knowledge will they be producing, and how will it be used? Science education now requires serious consideration of these philosophical and ethical questions. But the many different forms of knowledge produced by modern science cannot be covered (...) by any single philosophical principle. Sociology and cognitive psychology are also needed to understand what the sciences have in common and the significance of what they generate. Again, traditional modes of ethical analysis cannot deal adequately with the values, norms and interests activated by present-day technoscience without reference to its sociological, political and economic dimensions.
