Blindsight is the term commonly used to describe visually guided behaviour elicited by a stimulus falling within the scotoma (blind area) caused by a lesion of the striate cortex. Such is normally held to be unconscious and to be mediated by subcortical pathways involving the superior colliculus. Blindsight is of considerable theoretical importance since it suggests that destriate man is more like destriate monkey than had been previously believed and also because it supports the classical notion of two visual systems. (...) It is also of potential clinical importance, since it has been claimed recently that systematic practice in blindsight can lead to the recovery of normal visual function in patients with cortical lesions. From a review of the literature it is concluded that all of the phenomena of blindsight can be attributed either to light scatter into unimpaired parts of the visual field or to residual vision resulting from spared striate cortex. The possible contribution f other factors is also considered. It is concluded that blindsight studies have generally failed to control for such nonblindsight interpretations partly because of poor methodology and partly because of difficulties in defining the term.

In the problem of Meaning and Error, Epistemology, Logic, Psychology, and Etymology, all find an inevitable point of contact. It is necessary to go back little more than half a century to see something of the changes which have resulted in the present epoch of disintegration.

Why do women have more difficulty pursuing research careers than men? Although this topic has been extensively investigated in industrialized countries, prior studies provide little comparative evidence from less-developed areas. Based on a survey of 293 scientists in Ghana, Kenya, and the Indian state of Kerala, this article examines gender differences on a variety of individual, social, and organizational dimensions. The results show small or nonexistent differences between women and men in individual characteristics, professional resources, and the organizational conditions under (...) which research is conducted. The article argues that a combination of educational and research localism increases the likelihood of restricted professional networks for women. Gender inequality in the research systems of the developing world may be based on systemic deficits in the acquisition of social rather than material resources. The most important implication is that educational policy for development should focus on international opportunities for women in the near future. (shrink)

We show that the Lascar group $\operatorname {Gal}_L$ of a first-order theory T is naturally isomorphic to the fundamental group $\pi _1|)$ of the classifying space of the category of models of T and elementary embeddings. We use this identification to compute the Lascar groups of several example theories via homotopy-theoretic methods, and in fact completely characterize the homotopy type of $|\mathrm {Mod}|$ for these theories T. It turns out that in each of these cases, $|\operatorname {Mod}|$ is aspherical, i.e., (...) its higher homotopy groups vanish. This raises the question of which homotopy types are of the form $|\mathrm {Mod}|$ in general. As a preliminary step towards answering this question, we show that every homotopy type is of the form $|\mathcal {C}|$ where $\mathcal {C}$ is an Abstract Elementary Class with amalgamation for $\kappa $ -small objects, where $\kappa $ may be taken arbitrarily large. This result is improved in another paper. (shrink)

Let T be the theory of dense cyclically ordered sets with at least two elements. We determine the classifying space of $\mathsf {Mod}(T)$ to be homotopically equivalent to $\mathbb {CP}^\infty $. In particular, $\pi _2(\lvert \mathsf {Mod}(T)\rvert )=\mathbb {Z}$, which answers a question in our previous work. The computation is based on Connes’ cycle category $\Lambda $.

The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

Now in a third edition, Introduction to Philosophy: Classical and Contemporary Readings is a highly acclaimed, topically organized collection that covers five major areas of philosophy--theory of knowledge, philosophy of religion, philosophy of mind, freedom and determinism, and moral philosophy. Editor Louis P. Pojman enhances the text's topical organization by arranging the selections into a pro/con format to help students better understand opposing arguments. He also includes accessible introductions to each chapter, subsection, and individual reading, a unique feature for an (...) anthology of this depth. While the book focuses on a compelling sampling of classical material--including selections from Plato, Aristotle, Descartes, Locke, Berkeley, Hume, and Kant--it also incorporates some of philosophy's best twentieth-century and contemporary work, featuring articles by Bertrand Russell, Richard Taylor, John Searle, Thomas Nagel, and others. This third edition contains an expanded glossary, more extensive section introductions, and twelve new selections: Karl Popper: "Epistemology without a Knowing Subject" Richard Rorty: "Dismantling Truth: Solidarity Versus Objectivity" Daniel Dennett: "Postmodernism and Truth" Bruce Russell: "The Problem of Evil: Too Much Suffering" David Chalmers: "Against Materialism: Can Consciousness Be Reductively Explained?" Baron Paul Henri d'Holbach: "A Defense of Determinism" Michael Levin: "A Compatibilist Defense of Moral Responsibility" Plato: Socratic Morality: "Crito" Herodotus: "Custom Is King" J. L. Mackie: "The Subjectivity of Values" Louis P. Pojman: "A Critique of Mackie's Theory of Moral Subjectivism" Thomas Nagel: "Moral Luck". (shrink)

Rejecting information-processing-based theory permits the merging of a top-down analysis of visual search tasks with a bottom-up analysis of brain structure and function. This reveals the true nature of the functional visual field and its precise role in the conduct of visual search tasks. The merits of such analyses over the traditional methods of the authors are described.

La 4e de couverture indique : "Merleau - Ponty nous touche parce qu'il a vécu les fortunes et les infortunes de [esprit. En butte aux adversités du réel et notamment à celle d'une mort prématurée, son destin laisse voir que la pensée peut se formuler à elle-même des exigences peut-être impossibles à remplir. Il nous soumet encore, à sa manière, allusive ou détournée, passionnée, une certaine question, celle qui renaît sans cesse, au long du temps et des circonstances, et qui (...) se pose depuis l'origine de la philosophie occidentale comment la pensée naît-elle dans un homme, comment se développe - t - elle par sa propre puissance et contre d'autres pensées, comment poursuit-elle son chemin et son action dans l'Histoire, longtemps après que cet homme est mort? Comme celle de Husserl, comme celle de Sartre son alter ego et rival, mais plus discrète, plus légère, et presque oubliée, l'ombre active de Merleau - Ponty se porte encore sur nos chemins.".

Contrary to the narrative of collapse that attends much of the discussion of the humanities today, recent data suggest that for many programs in the United States, at least, stagnation is the real challenge. Committed to teaching models that support faculty rather than student needs, graduate programs, in particular, are struggling to extend their reach beyond an established constituency of students interested in traditional disciplinary specialization and academic research. By emphasizing the teaching of empathy and communication, which underlie the various (...) humanities disciplines, pursuing inter- and transdisciplinary teaching within and beyond the humanities, and securing administrative support for academic innovation, programs can find and serve a larger graduate student audience. Facing unique financial pressures, smaller colleges may prove more open to such innovation and merit greater attention in the discussion of the future of humanities graduate education. (shrink)

Pothos's analysis is difficult to relate to real human mental processes. He tackles four quite different areas of psychology and adduces evidence from a large number of paradigms. Yet despite this very large scope, he employs a single, simplistic descriptive framework. An epistemological analysis, supported by illustrations from real world decision-making, shows that this steers us away from, rather than towards, an understanding of real human cognitive processes.

This note presents an outline of the social and intellectual conditions accounting for the rise of “conspiracy entrepreneurs”, that is these heterodox thinkers who make a living from their denunciations and revelations on the malevolent organisations and characters who really lead the universe. A special attention has been focused on the reports concerning conspiracy entrepreneurs in the media, which describe them as eccentric and thus entertaining. After the presentation of some studies of David Icke's reptilian hypothesis, a question is raised: (...) is it not legitimate to assert that academics studying conspiracy theories are themselves conspiracy entrepreneurs through their role in the spread of the subject of their studies.
