This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.
Finally, in four chapters greatly expanded for this edition, Griffin considers the latest scientific research on animal consciousness, pro and con, and...
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 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 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.

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)
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.

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. (shrink)
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)

Levinas and Twentieth-Century Literature considers how the work of the century’s most original ethical thinker may reshape understandings of modernism, postmodernism, postcolonialism, feminism, gender studies, and globalism. Tracing how modernist technique and anti-totalizing ethics enter into relations that, by the turn of the twenty-first century, not only revitalize diverse national literatures but also produce post-national, migrant, or hybrid literatures, the collection illuminates the ethical within literature while disclosing the literary contexts of Levinasian ethics.
In animals' natural lives, uncertainty is normal; and certainty, exceptional. Evaluating ambiguous information is essential for survival: Does what is seen, heard, or smelled mean danger? Does that gesture mean aggression or fear? Is he confident or uncertain? If they are conscious of anything, the content of animals' awareness probably includes crucial uncertainties, both their own and those of others.
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)
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)
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)

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)
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.
. Hindu law represents one of the least known, yet most sophisticated traditions of legal theory and jurisprudence in world history. Hindu jurisprudential texts contain elaborate and careful philosophical reflections on the nature of law and religion. The nature of Hindu law as a tradition has been subject to some debate and some misunderstanding both within and especially outside of specialist circles. The present essay utilizes the familiar framework of legal realism to describe the fundamental concepts of law and legal (...) procedure in Hindu jurisprudence. Questions about the place of natural law theory and legal positivism in relation to Hindu law are also considered. (shrink)
What is the relationship between intellectual and cultural history? An answer to this question may be found in the area between the two poles of inquiry commonly known as internalist and externalist methods. The first of these deals with old-fashioned `ideas' (in Lovejoy's sense) and the second with social and political context and the sociology and anthropology of knowledge. This article reviews this question in the light of the earlier historiography of philosophy, literature and science, and debates over the role (...) of context in determining historical meaning. Within the horizon-structure of experience and interpretation the short answer is that cultural history is the outside of intellectual history and intellectual history the inside of cultural history. Ideally, historians ought to work both sides of the historical street. (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)
