I argue that consciousness is an aspect of an agent's intelligence, hence of its ability to deal adaptively with the world. In particular, it allows for the possibility of noting and correcting the agent's errors, as actions performed by itself. This in turn requires a robust self-concept as part of the agent's world model; the appropriate notion of self here is a special one, allowing for a very strong kind of self-reference. It also requires the capability to come to see (...) that world model as residing in its belief base , while then representing the actual world as possibly different, i.e., forming a new world-model. This suggests particular computational mechanisms by which consciousness occurs, ones that conceivably could be discovered by neuroscientists, as well as built into artificial systems that may need such capabilities. Consciousness, then, is not an epiphenomenon at all, but rather a key part of the functional architecture of suitably intelligent agents, hence amenable to study as much as any other architectural feature. I also argue that ignorance of how subjective states could be essentially functional does not itself lend credibility to the view that such states are not essentially functional; the strong self-reference proposal here is one possible functional explanation of consciousness.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Sightings of the revolutionary comet that appeared in the skies of evolutionary biology in 1976—the selfish gene—date back to the 19th and early 20th centuries. It became generally recognized that genes were located on chromosomes and compete with each other in a manner consistent with the later appellation “selfish.” Chromosomes were seen as disruptable by the apparently random “cut and paste” process known as recombination. However, each gene was only a small part of its chromosome. On a statistical basis a (...) gene should escape disruption for many generations. This led George Williams and Richard Dawkins to a new definition of the gene, differing from conventional biochemical definitions in that there were no consistent genic boundaries. There had been no previous sightings of another revolutionary, albeit less verbally spectacular, comet that appeared in 1975—the homostability principle of Akiyoshi Wada. Each gene has a base composition “accent” that distinguishes it from its neighbors. We now see that recombination can be triggered by the shift in base composition at genic boundaries. Hence, the Williams-Dawkins definition approaches the conventional definitions. (shrink)

This study blends together ethical philosophy, neurocognitive-evolutionary studies, and literary theory to explore how imaginative discourse addresses a distinctively human deep sociality, and by doing so helps shape cultural and literary history. Deep sociality, arising from an improbable evolutionary history, both entwines and leaves non-reconciled what is felt to be significant for us and what ethical sense seems to call us to acknowledge as significant, independent of ourselves. Ethical Sense and Literary Significance connects literary and cultural history without reducing the (...) literary to a mere expression of something else. It argues that affective differences between non-egocentric and egocentric registers of significance are integral to the bioculturally evolved deep sociality that verbal art addresses-often in unsettling and socially critical ways. Much imaginative discourse, in early societies as well as recent ones, brings ethical sense and literary significance together in ways that reveal their intricate but non-harmonized internal entwinement. Drawing on contemporary scholarship in the humanities and sciences, Donald R. Wehrs explores the implications of interdisciplinary approaches to topics central to a wide range of fields beyond literary studies, including neuroscience, anthropology, phenomenological philosophy, comparative history, and social psychology.

The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of incredible scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for evolution. In twenty-five vignettes, he recounts the dramatic stories of the people (...) who made crucial discoveries, placing each moment in the context of what it represented for the progress of science. He tackles topics like what it means to see evolution in action and the distance between species in space and time, following figures from Darwin to lesser-known researchers as they unlock the mysteries of the fossil record, the earth, and the universe. The book also features the stories of animal species strange and familiar, including humans-and our ties to some of our closest relatives and more distant cousins. Prothero's wide-ranging tales showcase awe-inspiring and bizarre aspects of nature and the powerful insights they give us into the way that life works. (shrink)

University of Chicago Press, 2001 Review by Adriano Palma, Ph.D. on Aug 1st 2001 Volume: 5, Number: 31.

The Cambridge Companion to Socrates is a collection of essays providing a comprehensive guide to Socrates, the most famous Greek philosopher. Because Socrates himself wrote nothing, our evidence comes from the writings of his friends (above all Plato), his enemies, and later writers. Socrates is thus a literary figure as well as a historical person. Both aspects of Socrates' legacy are covered in this volume. Socrates' character is full of paradox, and so are his philosophical views. These paradoxes have led (...) to deep differences in scholar's interpretation of Socrates and his thought. Mirroring this wide range of thought about Socrates, this volume's contributors are unusually diverse in their background and perspective. The essays in this volume were authored by classical philologists, philosophers, and historians from Germany, Francophone Canada, Britain, and the United States, and they represent a range of interpretive and philosophical traditions.

My purpose is to offer an assessment of the scientific legacy of Converse's “Belief Systems” by reviewing five productive lines of research stimulated by his authoritative analysis and unsettling conclusions. First I recount the later life history of Converse's notion of “nonattitudes,” and suggest that as important as nonattitudes are, we should be paying at least as much attention to their opposite: attitudes held with conviction. Second, I argue that the problem of insufficient information that resides at the center of (...) Converse's analysis has not gone away, and that newly fashioned models of information processing offer only partial remedies. Third, I suggest that the concept of the “average voter” is a malicious fiction, as it blinds us to the enormous variation in political attention, interest, and knowledge that characterizes mass publics, in Converse's time as in our own. Fourth, I develop an affirmative aspect of Converse's analysis that has mostly been overlooked: namely, that if ideological reasoning is beyond most citizens’ capacity and interest, they might fall back on a simple and reasonable alternative, which I will call “group‐centrism.” And fifth, I consider the possibility that while the majority of individual citizens falls short of democratic standards, the public as a whole might do rather well.

The view that the initiation of branching into two sympatric species may not require natural selection emerged in Victorian times. In the 1980s paleontologist Stephen Jay Gould gave a theoretical underpinning of this nongenic “chromosomal” view, thus reinstating Richard Goldschmidt’s “heresy” of the 1930s. From modeling studies with computer-generated “biomorphs,” zoologist Richard Dawkins also affirmed Goldschmidt, proclaiming the “evolution of evolvability.” However, in the 1990s, while Gould and Dawkins were recanting, bioinformatic, biochemical, and cytological studies were providing a deeper underpinning. (...) In 2001 this came under attack from leaders in the field who favored Dawkins’ genic emphasis. Now, with growing evidence for the uncoupling of speciation from adaptation, we can reinstate again Goldschmidt’s view and clarify its 19th-century roots. (shrink)

The influence of historiography on aspects of political thought in France, Italy and Germany. In recent years the overlap between political thought and historiography has changed the boundaries of intellectual history. Donald Kelley, the longtime editor of The Journal of the History of Ideas has played a leading part in this process. These essays by his friends and former students follow in his footsteps. The collection is divided into three parts: France, England [six essays], and Italy and Germany [four (...) essays]. Anthony Grafton and John Salmon provide an introduction, and the volume concludes with a bibliography of Donald Kelley's many works. Historians and Ideologues is designed for those with an interest in the contribution of historiography to political thought, and will be a timely addition to the growing reaction against the postmodern scepticism in historiographical research in this field. Contributors include Ann Blair, Julian Franklin, Kathleen Parrow, David Harris Sacks, Sarah Hanley, Daniel Woolf, Gordon Schochet, Joseph Levine, John Pocock, Perez Zagorin, William Connell, Donald Phillip Verene, and Michael Carhart. Anthony Grafton is a Professor in the Department of History at Princeton University. John Salmon is the Marjorie Walter Goodheart Emeritus Professor of History at Bryn Mawr College. (shrink)

The 'history of ideas', better known these days as intellectual history, is a flourishing field of study which has been the object of much controversy but hardly any historical exploration. This major new work from Donald R. Kelley is the first comprehensive history of intellectual history, tracing the study of the history of thought from ancient, medieval and early modern times, its emergence as the 'history of ideas' in the 18th century, and its subsequent expansion. The point of departure (...) for this study is the perspective opened up by Victor Cousin in the early 19th-century on 'Eclecticism' and its association with the history of philosophy established by Renaissance scholars. Kelley considers a broad range of topics, including the rivalry between 'ideas' and language, the rise of cultural history, the contributions of certain 19th- and 20th-century practitioners of the history of ideas in interdisciplinary areas of philosophy, literature and the sciences, and finally the current state of intellectual history. The central theme of the book is the interplay between the canon of philosophical thought and the tradition of language and textual study, the divergence of the latter marking the 'descent of ideas' into the realm of cultural history.

Eminent scientists are well-placed to bring the novel works of others, even if not in their own areas of expertise, to general attention. In so doing, they may be able to extend original accounts or introduce new terminologies, but they are basically messengers, not innovators. In the 1940s an evolutionary theory of biological aging was explained by Peter Medawar, and informational concepts relating to DNA were explained by Erwin Schrödinger. Both explanations were eventually traced back to the Victorian polymath Samuel (...) Butler—one by Medawar’s research associate Alex Comfort, and the other, albeit indirectly, by Schrödinger himself. In his time Butler’s works were too erudite for general readers and too laden with populist jargon for contemporary experts to take seriously. However, today it appears counterfactually plausible that an early acceptance of his ideas would have greatly quickened the pace of research. (shrink)

Four years after the death of Charles Darwin, his research associate, George Romanes, invoked a mysterious process—“physiological selection”—that could often have secured reproductive isolation independently of, and prior to, natural selection, so leading to an origin of species. This postulate of two sequential selection modes can now be regarded as leading to modern “chromosomal,” as opposed to “genic,” speciation theories. Romanes’ abstractions—which confounded many, but not all, of his contemporaries—equate with divergences in parental DNA sequences that impede meiotic pairing in (...) their hybrid offspring, so rendering that offspring sterile. Unlike Darwin, Romanes saw hybrid sterility as a parental, rather than offspring, phenotype that would, within a species, reproductively isolate certain parents from each other while not impeding their crossing with other parents. This group selection would have empowered natural selection to act more advantageously than in its absence. Given suitable conditions, there could then be divergence from one species into two. The present essay introduces Romanes’ “Physiological Selection; an Additional Suggestion on the Origin of Species” 19:337–411; available as supplementary material in the online version of this essay) for the journal’s “Classics in Biological Theory” collection.

A collection of essays from some of the world's leading intellectual historians, representing an international spectrum of research into the history of philosophy, intellect, science and music. This collection of essays addresses, in specific historical ways and from particular disciplinary standpoints, the problem of knowledge and what used to be called the classification of the sciences. What is, or what passes for, knowledge? What are its divisions, and how should they be related? Who possesses this knowledge, and to what uses (...) has it been put? How is it transmitted, and how can its history be understood and written? Ranging across the epistemological barrier formed by the revolution of modern science, these contributions inquire into the changing disciplinary patterns of the tumultuous times between the renaissance and the enlightenment, that saw the fragmentation of old ideals and the creation of European modernity. Contributors: Donald R. Kelley, Ann Blair, Paul Nelles, Constance Blackwell, Ulrich Schneider, Martin Mulsow, J.B.

The history of ideas is an interdisciplinary field that began as an offshoot of the history of philosophy and was transformed by notions of perspective and cultural context drawn from the tradition of historical studies. The result is the practice of intellectual history, which has been carried out between the poles of inquiry commonly known as internalist and externalist, corresponding to mental phenomena and collective behavior in cultural surroundings. These are not opposed but rather complementary methods, and intellectual history may (...) be seen as the inside of cultural history and cultural history as the outside of intellectual history, the intellectual historian's task being to bring the two into alliance.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.4 (2001) 577-592 [Access article in PDF] Eclecticism and the History of Ideas Donald R. Kelley "What we call the history of ideas," Joseph Mazzeo wrote in in 1972, "itself has a history." 1 In this country the history of ideas in the past century has been associated with the American philosopher and founder of this journal, Arthur O. Lovejoy, and his (...) epigones and critics. However, this field has an earlier history sub literam, going back almost two centuries, and a still deeper prehistory before the coinage of the phrase, traceable at least indirectly back to antiquity. The purpose of this essay is to trace some aspects of one intellectual tradition out of which the history of ideas has, knowingly or not, emerged.In 1829 Victor Cousin gave a diagnosis of and his prescription for philosophy in the wake of one revolution and on the threshold of another. He saw just three possibilities: either it could renounce its independence and submit again to authority, it could keep on retracing the circle of obsolescent systems, or--and this was his solution--it could "disengage what is true in each of these systems, and thus construct a philosophy superior to all systems [and] shall be neither this or that philosophy in its essence and in its unity." This procedure, "to select in all what appears to be true and good, and consequently everlasting,--this, in a single word, is ECLECTICISM." Moreover, Cousin added, "[i]f this philosophy is to be Eclectic, it must also be sustained by the history of philosophy."How had Cousin come upon this program? In December 1815, in the first year of both the Restoration Monarchy and his teaching at the École Normale Supérieure, he was lecturing on the history of philosophy. In post-revolutionary France this was a field in great disarray, and Cousin looked back to the great schools of the earlier generation, noting three in particular--the French, the [End Page 577] Scottish, and the German traditions, represented respectively by Condillac, Reid, and Kant. "It would be an interesting and instructive study," he told his enthusiastic young students, "to examine the weaknesses of these schools by engaging one with another and by selecting their various merits in the context of a great eclecticism which would contain and surpass all three." 2Over the next three decades this doctrine was publicized and extended by Cousin's many scholarly publications, by the still more famous lectures he gave after returning to his chair of philosophy in 1828, by his many international contacts and disciples, and by his later public career as minister of education. 3 For half a century before his death in 1867 Cousin had an unparalleled intellectual influence as virtually the "official philosopher" in France, with Eclecticism being widely regarded as a "state philosophy," 4 and translations of his works extending his renown into other parts of Europe and this country. In defending his achievements and hegemonic position Cousin claimed an absolute originality and a unique truth-value for his ideas. Eclecticism had not been drawn from German sources, he protested in 1855. "It was born spontaneously in our own spirit [notre esprit] from the spectacle of the resounding conflicts and the hidden harmonies of the three great philosophical schools of the eighteenth century," he declared. "Thus," he concluded, "eclecticism is a French doctrine and peculiar to us." 5Historically speaking, however, nothing could be further from the truth--or indeed further from the premises of the earlier eclectic tradition on which Cousin knowingly drew. The defining characteristic of his philosophy was its dependence not only on the three schools he recognized in his early years of teaching but on the whole history of philosophy from its Greek and especially Platonic beginnings, to which Cousin himself devoted much of his historical and philological [End Page 578] scholarship. That Eclecticism was a sort of higher plagiarism was admitted by Cousin himself: "What I recommend," Cousin said in 1817, "is an enlightened eclecticism which, judging with equity, and even with benevolence...

While its mechanism and biological significance are unknown, the utility of a short mitochondrial DNA sequence as a “barcode” providing accurate species identification has revolutionized the classification of organisms. Since highest accuracy was achieved with recently diverged species, hopes were raised that barcodes would throw light on the speciation process. Indeed, a failure of a maternally donated, rapidly mutating, mitochondrial genome to coadapt its gene products with those of a paternally donated nuclear genome could result in developmental failure, thus creating (...) a post-zygotic barrier leading to reproductive isolation and sympatric branching into independent species. However, the barcode itself encodes a highly conserved, species-invariant, protein, and the discriminatory power resides in the non-amino acid specific bases of synonymous codons. It is here shown how the latter could register changes in the oligonucleotide frequencies of nuclear DNA that, when they fail to match in pairing meiotic chromosomes, could reproductively isolate the parents so launching a primary divergence into two species. It is proposed that, while not itself contributing to speciation, the barcode sequence provides an index of the nuclear DNA oligonucleotide frequencies that drive speciation. (shrink)

Quantum probability theory offers a viable alternative to classical probability, although there are some ambiguities inherent in transferring the quantum formalism to a less determined realm. A number of physicists are now looking at the applicability of quantum ideas to the assessment of physics learning, an area particularly suited to quantum probability ideas.
