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.

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. Contributors: Donald R. Kelley, Ann Blair, Paul Nelles, Constance Blackwell, Ulrich Schneider, Martin Mulsow, J.B.

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)

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 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.

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)

In lieu of an abstract, here is a brief excerpt of the content:From the Executive EditorDonald R. KelleyTwenty years ago the Journal of the History of Ideas moved from Temple University to the University of Rochester (through the efforts especially of J. Paul Hunter, then dean of the college of arts and sciences, and Lewis White Beck, professor of philosophy), and I replaced Philip Wiener, who had been editor for forty-five years, the first issue under my supervision being that of (...) July 1985. A year later Robin Ladrach joined me as assistant and then as associate editor, and in 1991 we both moved along with the JHI to Rutgers University (through the efforts especially of Richard McCormick, then dean of the faculty of arts and sciences and now president of the university). Now the Journal has moved to the University of Pennsylvania, and I pass on the editorship to a committee composed of Warren Breckman, Martin J. Burke, Anthony Grafton, and Ann E. Moyer, with Robin Ladrach continuing as managing editor.We changed our face in 1990, but otherwise we have maintained a remarkably steady course since the days of Arthur O. Lovejoy, original founder of the JHI in 1940, with articles submitted and articles published continuing in mostly the same quantity and intellectual range and following the interdisciplinary and cross-cultural vision established by Lovejoy in the 1930s (history of philosophy, science, political thought, historiography, religion, literature, art, and music) but also modified by intervening intellectual and cultural changes (and so enhanced by studies in the human sciences, gender, women's history, globalism, animals, etc.). Such change has for the most part not been from conscious editorial policy, except indirectly, but rather "from below," and the role of the editor has been that not of cultural critic but of observer, whose reflections have appeared in "Horizons of Intellectual History," JHI, 48 (1987), 143–69; "What is Happening to the History of Ideas?" JHI, 51 (1990), 3–25; "JHI 2000," JHI, 61 (2000), 153–56; and The History of Ideas: Canon and Variations (Rochester, N.Y., 1990), which contains also the reflections of Lovejoy and other earlier authors. The new regime may well introduce new departures, but I [End Page 475] believe that it will continue to rely and perhaps draw on the old Lovejovian tradition which has made this journal a successful and enduring international enterprise.Donald R.

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.

Obituary for Joseph M. Levine, Distinguished Professor of History at Syracuse University.

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)

My commentary calls attention to what makes Mr. Bowie's paper well worth intensive consideration. In my brief evaluation, however, I only lay out three incoherent elements of his proposed family model of labor-management relations.I argue that complete job security is not compatible with complete freedom to change firms; that, in practice, such security for all employees is not compatible with the shifting demand of our economic system, and that the model includes two kinds of spouse relationships — one affectional and (...) another competitive — that are incoherent with one another. My point is not that Mr. Bowie's model is fatally flawed, but that it needs to be improved. (shrink)

Summary This paper is concerned with a mechanical calendar described by the great scientist al-B?r?n?, who died in 440/1048. The description occurs in a book devoted to the construction of various types of astrolabe and related instruments. The Arabic text presented in this paper was prepared from three manuscripts. This is preceded by a brief introduction which gives a sketch of the life and works of al-B?r?n? together with information about the provenance and contents of the three manuscripts. The text (...) is followed by an English translation and the paper concludes with a technical commentary which discusses the construction and operation of the instrument. This commentary is accompanied by explanatory drawings reconstructed from al-B?r?n?'s descriptions. Photographs from the illustrations in the manuscripts are also provided. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Romanian Cultural and Political IdentityDonald R. KelleyThe Journal of the History of Ideas, in collaboration with other institutions, including the Universities of Bucharest and Budapest and the Soros Foundation, recently sponsored the second in a series of international conferences being planned on topics in current intellectual history. (The first, “Interrogating Tradition,” was held at Rutgers University, 13–16 November 1997.) The Romanian conference, which was held in the Elisabeta Palace (...) in Bucharest (27–31 May 1998), was devoted to “Culture and the Politics of National Identity in Modern Romania.” Over forty scholars, mainly from Romania but some also from the U.S., France, Germany, and Hungary, gathered to discuss a variety of questions about Romanian society, past, present, and speculative future; and they were joined by at least as many visitors, especially students, from the local area and beyond.Topics discussed included politics, language, economics, historiography, religion, education, philosophy, ideologies, intelligentsia, particular intellectuals, minorities, and women (though not Gypsies or gays). Under this riot of rubrics a wide range of questions were posed in interdisciplinary fashion, with frequent, sometimes impassioned interventions. What is—was, might have been, can be—Romania? Who is a Romanian (and who not)? What is Romania’s relation to the West and the East? (And what are the “West” and the “East”?) To modernity, to modernism, to modernization? What is—has been, should be—the function of intellectuals, of political and cultural elites, in understanding the Romanian past and in setting a course for the future? What, more generally, is the role of history in answering such questions? Or is history perhaps (as Karl Krause remarked of psychoanalysis) the disease for which it claims to be the cure?Keith Hitchens’s keynote address suggested that rehashing old essentialist debates might not be productive at millennium’s end, but the conference itself could not avoid some excursions down the paths of memory and myth. For historians, Western historians anyway, Romania seems to have too many pasts. Located at the juncture of four previous empires, Romania is a mosaic, or perhaps a pandemonium, of ethnic, religious, economic, and ideological groups that can only imagine, or invent, a nationality. Geographically (and in many ways culturally) remote from the West, Romania for a long time (as Sorin Antohi remarked) lacked both a public sphere and a civil society; and suffering “a Counter-Reformation without a Reformation” (Alexandru Dutu’s phrase), it has not enjoyed a tradition of religious or ethnic toleration. Nor have either the Germans or the Jews (as Glass said) found their own unity within the changing borders of the modern Romanian state. Not until the nineteenth century did Romania develop, out of its Boyar background (as Siupiur argued), an intellectual elite that could create a modern national history and help turn “peasants into Romanians” (Antohi’s phrase); and even then this elite seemed more attracted to conservative [End Page 735] (Herder, Savigny, Burke) than to liberal views of autochthonism. Many features of Western modernity, such as Newtonian science, reached Romania late, and indeed there was a retrograde movement against liberalism under the aegis by orthodox religion. In any case this intelligentsia has been as fragmented and multiform as the Romanian past itself. True, some Romanian scholars like to posit a mainstream tradition, “excesses aside,” as one speaker put it—but how, asked another, can historians put “excesses” aside from the devastating perspective of this century?Political and cultural self-examination was the dominant theme of this conference. Nationality, said Pippidi, depends on three factors, viz., name, language, religion, and territory. The Romanian name dates from the tenth century, indicating a separation of the Roman from the Greek tradition in Wallachia; and from the seventeenth century the idea of a mainly Roman provenance was given privilege. As a language, “Romanian” was spoken in the late Middle Ages, but the first written document is dated 1521. The principal religion in Romania was and is Greek orthodox, although there are also Roman Catholic, Jewish, Islamic, and German Protestant communities, as well as the Uniate church created in the eighteenth century. As for the territory, this has been a matter of change, conflict, and confusion throughout the tragic course... (shrink)

Knowing how introns originated should greatly enhance our understanding of the information we carry in our DNA. Gilbert’s suggestion that introns initially arose to facilitate recombination still stands, though not for the reason he gave. Reanney’s alternative, that evolution, from the early “RNA world” to today’s DNA-based world, would require the ability to detect and correct errors by recombination, now seems more likely. Consistent with this, introns are richer than exons in the potential to extrude the stem-loop structures needed for (...) the homology search that can lead to heteroduplex formation and the recognition of base mismatches. In nucleic acid sequences that were unable concomitantly to encode sufficient stem-loop potential, protein-encoding potential was constrained to arise as segments (exons) interrupted by segments rich in stem-loop potential (introns). Thus, sequences with properties that we now deem intronic are likely to have preceded the emergence of exons. (shrink)

A consideration of underlying neural dynamics and the evolutionary process producing cognitive agents should complement the development of dynamical models of behavior. The geometrical aspects of dynamical systems theory which make it useful in the description of systems acting in an environment are less useful in understanding agents interacting with a range of environments, and may call for supplementation by evolutionary insights.

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)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.1 (2000) 153-156 [Access article in PDF] JHI 2000 Donald R. Kelley It was just sixty years ago that this Journal first made its appearance. Two hundred thirty-nine issues later it continues in a world transformed by war, overpopulation, cultural shocks, scientific and technological transformations, globalization, the avalanche of information produced by electronic exchange, and "the acceleration of just about everything." Yet (...) despite these factors and the strains of postmodernism and cultural alterity, 1 it has not entirely lost touch with its intellectual innocence, faith in humanistic learning, and reliance on enlightened reason. This continuity itself may seem something of a novelty in an age of distrust of history and "rage against reason," but for some of us it reflects the critical spirit and intellectual context out of which such ostensibly subversive attitudes emerge, and reemerge. To some extent, moreover, the diversity of opinions about intellectual traditions is the result of specializations, and special interests, which have changed the climate of opinion since the time of Arthur O. Lovejoy, principal founder of the JHI. Lovejoy's vision was super- as well as inter-disciplinary; that is, he intended to include in the agenda of "history of ideas" particular areas of history of philosophy, literature, art, science, social science, etc., as well as the larger intellectual and cultural areas into which these disciplinary histories extend. 2 These days, however, all these disciplinary traditions have their own more specialized journals and do not need to seek a vehicle in publications of more general interest. What remains then, for the most part, is the interdisciplinary arena in which larger questions of human experience should be posed--and for Lovejoy, as for so many epigones and critics, the main "larger question" is not only one of value but also of specifically historical inquiry. 3 [End Page 153]The first issue of the JHI appeared under the editorship of Lovejoy (with Philip Wiener, who did most of the editorial work, as "managing editor"), assisted by a committee that included two historians, three philosophers, four literary scholars, and one political theorist; namely, Crane Brinton, Gilbert Chinard, Morris Cohen, Francis Coker, Richard McKeon, Perry Miller, Marjory Nicolson, J. H. Randall, J. Salwyn Schapiro, and Louis Wright. The first volume featured contributions from each of these, including Wiener, except for Miller (vol. 2), Shapiro (vol. 3), McKeon (vol. 8), and Coker. 4 During the first five years there were also reviews of books by Dilthey (by Horace L. Friess), Croce (Schapiro), Mannheim (Randall), Perry Miller (Herbert W. Schneider), Van Wyck Brooks (Miller) and Alfred Kazin (F. O. Matthiessen). In this period the disciplinary distribution of articles was not markedly different from that of the past five years, nor was the ranking of fields by number of submissions. 5 Most important, the original interdisciplinary thrust of Lovejoy's agenda, if not his attachment to the spiritualist currency of "unit-ideas," has survived growing specialization.At first the history of ideas was pursued largely in the shadow of the history of philosophy; for in this field, according to Lovejoy, "is to be found the common seed-plot, the locus of initial manifestation in writing, of the greater number of the more fundamental and pervasive ideas, and especially of the ruling preconceptions, which manifest themselves in other regions of intellectual history." 6 Lovejoy's concern was always with concepts, especially "-isms," and yet in some ways he anticipated the "linguistic turn" of the later years of this century, pointing out in particular "the role of semantic shifts, ambiguities, and confusions, in the history of thought and taste," for "nearly all of the great catchwords have been equivocal--or rather, multivocal." 7 If ideas could be given stable definitions, they were nonetheless often, in the context of language, in conflict, even in the mind of a single thinker; for such was the "anomaly of knowledge." 8 So Lovejoy was at pains to distinguish the various meanings of [End Page 154] catch-words like "nature," "perfectibility," "romanticism," "progress," and "pragmatism," not to mention more inflammatory terms of wartime ideological debate.But...

Examples of terror generated by an aircraft disaster, of human courtship behaviour, and of the application of laboratory techniques to the commercial training of animals suggest (1) that emotion is simply the subjective counterpart of (objective) motivation (so that separate brain mechanisms would be an embarrassment) and (2) the apparent involvement of reward and punishment is a consequence of the excessively narrow range of experimental procedures used and has no foundation in the design of the brain.

Notes and Discussions Philodoxy: Mere Opinion and Question of History the "Philosophy as... rigorous science-- the dream is over." Edmund Husserl 1. MERE OPINION From the beginning philosophy has not only had a love affair with wisdom but also a special claim on truth and a concomitant contempt for mere opinion. Parmenides left a poem in which he contrasted the "way of truth," which was the path taken by Plato and his followers, with the "way of opinion," which was paved (...) with falsehood and deceit.' Arcesilaus defended opinion in the sense that he refused to concede certain truth to any ideas2 On such grounds Cicero concluded that the wise man should hold no opinions.s In the self-constituting canon of philosophy "opinion" has always been a pejorative term, designating an inferior sort of knowledge based not on demon- stration but on belief and associated in particular with the much-maligned Sophists, who languished under a "dark shadow" for centu- ries.4 As Macrobius wrote: "Opinion is born of failure of memory," meaning the preexistent form of knowledge -- ideas -- which was Platonic recollection;5 and for Aquinas, "opinion is knowledge of those things about which we do not have certain knowledge. ''6 In general, questions of "opinion" or "prejudice" have seldom been posed by 'Jonathan Barnes, The Presocratic Philosophers , 156. See also T. Sprute, Der Begriff der doxa in der platonische..
