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.

It has recently been suggested by Richard R. La Croix that there is a logical incompatibility between the doctrine of divine omniprescience — the notion that God knows what will happen in the future — and the commonly held belief that literary authors are creative with respect to the compositions they produce. This suggestion is, I take it, part of the overall claim that God's omniscience rules out human free choices, since if what one does is known before one does (...) it, then one can hardly be said to have chosen it. I will not, however, be concerned with this general controversy in the present paper, but rather with the specific one regarding literary creativity and divine omniprescience. La Croix defends this claim by defining literary creativity as follows: literary authorship is creative in the sense that by means of his composing activity an author is an agent who brings about the existence of some thing which did not exist prior to the composing activity of that agent and which would not exist without the composing activity of that agent or some similar agent.

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)

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.

In a recent article in Religious Studies , Gregory S. Kavka argues that John Hick was wrong when he said that the statement ‘God exists’ is verifiable but not falsifiable. Kavka constructs an imaginary `resurrection world' ruled by Satan and inhabited by such resurrected evildoers as Hitler and Stalin. In such a world, those who had been virtuous in earthly life in the hopes of a Christ-dominated resurrection world discover that virtue is inversely rewarded, with the ‘living’ intolerable for them (...) and worst of all for those among them who had lived especially virtuous lives, i.e. the saints. Further, they are told by presumably knowledgeable inhabitants of this world that: …the historical Christ was an agent sent by Satan to raise in good people false hopes of eternal salvation. This story is confirmed by Satan himself who demonstrates through a huge telescope-like device how he continues to send false saviours to other planets inhabited by intelligent beings in a cruel plan to make such beings miserable in the long run.

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)

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)

A biological explanation for the dependence of genome-wide mutation-rate variation on local base context is now becoming clearer. The proportions of G + C relative to A + T—expressed as GC%—is a species-specific DNA character. The frequencies of these single bases correlate with frequencies of corresponding oligonucleotides that are more-sensitive indicators of species specificity. Thus, when k = 3 there are 64 possible trinucleotide sequences and a GC%-rich species has a high frequency of GC-rich 3-mers. Closely related species have similar (...) k-mer patterns. For distantly related species, even if happening to have the same GC% values, k-mer patterns are widely discordant. Conventionally, a base substitution mutation is viewed as a chemical 1-mer phenomenon. However, the selective difference by which the corresponding mutation is scored usually relates to context. Thus, an A to U codon mutation in sickle cell anemia, rather than attracting an anticodon in a structural loop of glutamate tRNA, pairs with the more complementary anticodon loop of valine tRNA. Likewise, a recent statistical analysis of genome-wide mutation-rate variation supports the view that a failure of discordant DNA loops to pair at meiosis can initiate and/or sustain the speciation process. Such disharmony among base patterns may have unknowingly been hinted at by geneticist William Bateson who invoked a music metaphor when considering speciation mechanisms. (shrink)

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 , 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 scholars' interpretations 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 '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.

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.

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.

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.

The philosopher Ludwig Wittgenstein chose as his prime exemplar of certainty the fact that the skulls of normal people are filled with neural tissue, not sawdust. In 1980 the British pediatrician John Lorber reported that some normal adults, apparently cured of childhood hydrocephaly, had no more than 5 % of the volume of normal brain tissue. While initially disbelieved, Lorber’s observations have since been independently confirmed by clinicians in France and Brazil. Thus Wittgenstein’s certainty has become uncertain. Furthermore, the paradox (...) that the human brain’s information content appears to exceed the storage capacity of even normal-sized brains, requires resolution. This article is one of a series on disparities between brain size and its assumed information content, as seen in cases of savant syndrome, microcephaly, and hydrocephaly, and with special reference to the Victorian era views of Conan Doyle, Samuel Butler, and Darwin’s research associate, George Romanes. The articles argue that, albeit unlikely, the scope of explanations must not exclude extracorporeal information storage. (shrink)

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)

Observations suggesting the existence of natural antibody prior to exposure of an organism to the corresponding antigen, led to the natural selection theory of antibody formation of Jerne in 1955, and to the two signal hypothesis of Forsdyke in 1968. Aspects of these were not only first discoveries but also foundational discoveries in that they influenced contemporaries in a manner that, from our present vantage point, appears to have been constructive. Jerne’s later hypothesis (1971, European Journal of Immunology 1: 1–9), (...) that antibody-like receptors on lymphocytes were selected over evolutionary time for reactivity with the major histocompatibility complex (MHC) antigens of the species, was a first, but it was incorrect, and was foundational only to the extent that it emphasized the need to explain the Simonsen phenomenon. Although easily construed as derivative of Jerne (1971), the affinity/avidity model of Forsdyke (1975, Journal of Theoretical Biology 52: 187–198), which predicted that cell-surface components, including MHC antigens, would restrict antigen-reactivity by somatically shaping lymphocyte repertoires, was actually an extension of the two signal hypothesis. While presenting a mechanism for the positive selection of lymphocyte repertoires, and explaining the Simonsen phenomenon, the affinity/avidity model was not foundational in that it had to be independently rediscovered. For science to advance optimally we must seek to close temporal gaps so that first discoveries are also foundational. Listening to young scientists may be part of the solution. (shrink)

In a regressive tax system, lower-income taxpayers pay larger percentages of their incomes in taxes compared to higher-income taxpayers. Although most policymakers and citizens view regressive taxation as generally unfair and unethical, the U.S. tax system taxes wage, salary, and self-employment income in a manner that deliberately subjects lower-income taxpayers to marginal tax rates that are greater than those imposed on higher-income taxpayers. As a result, some lower-income taxpayers pay a larger percentage of their income in taxes than higher-income taxpayers. (...) In this essay, we argue that this regressiveness in the taxation of salaried income is unfair and unethical. We then evaluate President Obama’s social security plan, which would retain most of the current tax system’s regressive structure. Finally, we offer two simple alternative proposals that are non-regressive, and thus more fair and ethical approaches to the taxation of salaried income. (shrink)

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...

In this book, one of the world's leading intellectual historians offers a critical survey of Western historical thought and writing from the pre-classical era to the late eighteenth century. Donald R. Kelley focuses on persistent themes and methodology, including questions of myth, national origins, chronology, language, literary forms, rhetoric, translation, historical method and criticism, theory and practice of interpretation, cultural studies, philosophy of history, and "historicism." Kelley begins by analyzing the dual tradition established by the foundational works of Greek (...) historiography--Herodotus's broad cultural and antiquarian inquiry and the contrasting model of Thucydides' contemporary political and analytical narrative. He then examines the many variations on and departures from these themes produced in writings from Greek, Roman, Jewish, and Christian antiquity, in medieval chronicles, in national histories and revisions of history during the Renaissance and Reformation, and in the rise of erudite and enlightened history in the seventeenth and eighteenth centuries. Throughout, Kelley discusses how later historians viewed their predecessors, including both supporters and detractors of the authors in question. The book, which is a companion volume to Kelley's highly praised anthology Versions of History from Antiquity to the Enlightenment, will be a valuable resource for scholars and students interested in interpretations of the past.
