This study describes the results of experiments motivated by an attempt to understand spectral processing in the cerebral cortex (DeValois and DeValois, 1988; Pribram, 1971, 1991). This level of inquiry concerns processing within a restricted cortical area rather than that by which spatially separate circuits become synchronized during certain behavioral and experiential processes. We recorded neural responses for 55 locations in the somatosensory (barrel) cortex of the rat to various combinations of spatial frequency (texture) and temporal frequency stimulation of their (...) vibrissae. The recordings obtained from single and multi-unit bursts of spikes were mapped as surface distributions of local dendritic potentials. The distributions showed a variety of patterns that are asymmetric with respect to the spatial and temporal parameters of stimulation, and were, therefore, not simply reflecting whisker flick rate. Next, a simulation of our results showed that these surface distributions of local dendritic potentials can be described by Gabor-like functions much as in the visual system. The results provide support for a model of distributed cortical processing that imposes a physiologically derived frame (the limited extent of a dendritic patch) and an anatomically derived (axonal) sampling of the distributed process. This combination provides a complex Gabor wavelet that encodes phase, which is necessary to processing such details as edges and texture in a scene. The synchronization across cortical areas that make the Gabor wavelet processes within restricted cortical areas available to one another (the binding problem) proceed at a ''higher order'' level of integration. Both levels of distributed processing accomplish computation in the conjoint spacetime and spectral domain. (shrink)

This article contends that Socratic wisdom (sophia) in Plato's Apology should be understood in relation to moderation (sophrosune), not knowledge (episteme). This stance is exemplified in an interpretation of Socrates' disavowal of knowledge. The god calls Socrates wise. Socrates holds both that he is wise in nothing great or small and that the god does not lie. These apparently inconsistent claims are resolved in an interpretation of elenchus. This interpretion says that Socrates is wise insofar as he does not believe (...) himself to know what he does not know. Whether one knows is demonstrated through elenchus, which moderates between knowledge claims. Thus, elenchus is productive of a kind of wisdom even if it does not produce knowledge. This claim, if true, forms a suitable basis for Socrates' defense of himself. That it does so serves as further evidence for the interpretation of sophia as sophrosune. (shrink)
This paper reviews the experience of an integrated approach to CSR in the U.S. electric utility sector. The authors report on the results of Southern Company’s historical definition of CSR as a dynamic model, balancing stakeholder needs through shifting pressures to assure long-term shareholder value, superior customer, price performance, and sustainable economic development. Using financial and utility sector measures, the paper assesses the company’s “balancing” approach to addressing CSR, which weights corporate, environmental, community, and economic factors in driving successful and (...) sustained financial, social, and environmental performance. The paper concludes by suggesting that CSR success in this sector requires, first, that the global warming issue be governed by the same balancing considerations to which all stakeholders and their legitimate interests are subject, and second, an energy policy that embraces both atechnology policy and appropriate regulatory incentives.

Through the critical examination of Baudrillard's concept of hyperreality, this article seeks to make a wider contribution to contempor ary debates about postmodernism. It draws on a post-Cartesian, Heideg gerian philosophy to demonstrate the weakness of the concept of hyperreality and reveal its foundation in a Cartesian epistemology. The article goes on to claim that this same Heideggerian tradition suggests a way in which the concept of hyperreality and nihilistic postmodern sociologies more generally might be dialectically superseded. Instead of these (...) theories being seen as saying anything insightful about recent social transformations, the epistemological void in which they position themselves should be inter preted as the intellectual expression of the wider cultural and postmodern trend of transgression. Key Words: Baudrillard • Cartesianism • Heidegger • hyperreality • postmodernism. (shrink)
At least since Russell’s influential discussion in The Principles of Mathematics, many philosophers have held there is a problem that they call the problem of the unity of the proposition. In a recent paper, I argued that there is no single problem that alone deserves the epithet the problem of the unity of the proposition. I there distinguished three problems or questions, each of which had some right to be called a problem regarding the unity of the proposition; and I (...) showed how the account of propositions formulated in my book The Nature and Structure of Content [2007 Oxford University Press] solves each of these problems. In the present paper, I take up two of these problems/questions yet again. For I want to consider other accounts of propositions and compare their solutions to these problems, or lack thereof, to mine. I argue that my account provides the best solutions to the unity problems. (shrink)
stance, Scotus adopts Anselm’s notion of a ‘(pure) perfection’ and elevates it to a fundamental principle of his metaphysics. Again, he distills Anselm’s Ontological Argument into something like its original Monologion components, and then treats each component part of the argument with a rigor and attention to detail far beyond anything Anselm suggested. In the case of Anselm’s so-called ‘two-wills’ theory, however, Scotus’s revisions are so extensive that they amount to a rejection of Anselm’s account, even though Scotus retains some (...) of Anselm’s terminology. I’ll begin by looking at Anselm’s initial presentation of the two-wills theory in his De casu diaboli (§1), and his later refinements of that account in his De concordia (§2). I’ll then look at Scotus’s deployment, revision, and rejection of Anselm’s theory in his three discussions of angelic sin: Lect. 2 d. 6 q. 2 (§3), Ord. 2 d. 6 q. 2 (§4), and Rep. 2 d. 6 q. 2 (§5). This will be followed by a brief look at whether Scotus’s theory of the self-regulating will is an adequate replacement for Anselm’s account (§6). (shrink)
[1] In twelve quite demanding chapters, outstanding scholars provide an overall view of the key issues of Scotus’s philosophical thought. To this a very concise introduction is added, concerning the life and works of John Duns (very good, especially the survey of works and the information on critical editions etc.). Throughout the book, I find the information clear and the difficult topics well explained. Moreover, the volume gives a quick entrance to the vast literature. Among the topics discussed are: ‘Metaphysics’ (...) (Peter King), ‘Universals and Individuation’ (Timothy Noone), ‘Modal Theory’ (Calvin Normore), ‘Natural Theology’ (James Ross & Todd Bates), ‘Philosophy of Mind’ (Richard Cross), ‘Cognition’ (Robert Pasnau), ‘Moral Dispositions’ (Bonnie Kent). What strikes the eye is the absence of important theological subjects: Trinity, Christology, sin and grace, to name a few. Since the cover text promises that ‘the essays in this volume systematically survey the full range of Scotus’ thought’, this omission is remarkable. It stems, I guess, from the strict philosophical scope of the series of the Cambridge Companions, but such a limitation should have been recognised explicitly: this companion provides, in fact, an introduction to John Duns’s philosophy—i.e., philosophy in our modern sense. Of course, this separation of philosophical from theological thought is not from Scotus. Most of his innovative ‘philosophical’ ideas are developed in a profoundly theological context! (shrink)
Previous studies investigating reports of corporate or individual wrongdoing have failed to examine the effects of an organization's structure upon the decision to blow the whistle. This paper suggests that an organization's structure may perform a significant role in the decision to report versus not report an observed wrongdoing. Five organizational structures (that is, centralized, matrix, horizontal, hybrid, and divisional) were examined in regards to their effectiveness in encouraging or discouraging observers of unethical conduct channels for reporting such behavior. Discussion (...) and implications are provided. (shrink)
In Carnap’s autobiography, he tells the story how one night in January 1931, “the whole theory of language structure” in all its ramifications “came to [him] like a vision”. The shorthand manuscript he produced immediately thereafter, he says, “was the first version” of Logical Syntax of Language. This document, which has never been examined since Carnap’s death, turns out not to resemble Logical Syntax at all, at least on the surface. Wherein, then, did the momentous insight of 21 January 1931 (...) consist? We seek to answer this question by placing Carnap’s shorthand manuscript in the context of his previous efforts to accommodate scientific theories and metalinguistic claims within Wittgenstein’s Tractatus theory of meaning. The breakthrough of January 1931 consists, from this viewpoint, in the rejection of the Tractatus theory in favor of the meta-mathematical perspective of Hilbert, Gödel, and Tarski. This was not yet the standpoint of the published Logical Syntax, as we show, but led naturally to the “principle of tolerance” and thus to Carnap’s mature philosophy, in which the inconsistencies between this first view and the principle of tolerance, which survived into the published Syntax, were overcome.

For a biological anthropologist interested in the prehistory of religion, J. Wentzel van Huyssteen's book is welcome and resonant. Van Huyssteen's central thesis is that humans' capacity for spirituality emerges from a transformation of cognition and emotions that takes place in the symbolic realm, within Homo sapiens and apart from biology. To his thesis I bring to bear three areas of response: the abundant cognitive and emotional capacities of living apes and extinct hominids; the role of symbolic ritual in the (...) evolutionary history of Homo sapiens; and the closely intertwined nature of biology and culture in the workings of evolutionary change.

The concept of structure is central to Giddens's structuration theory because it apparently accounts for the reproduction of the social system without derogating the lay actor in functionalist or structuralist fashion. In fact, the concept of structure involves the very derogation of the lay actor which Giddens highlights as the principal error of these objectivist social theories and which he wishes to avoid. However, although Giddens fails to recognize it, the concept of "practical consciousness" which Giddens also regards as central (...) to structuration theory avoids this relapse into objectivism and offers a route to a sustainable social theory which highlights the agency of social actors. Key Words: structuration theory • practical consciousness • structure • hermeneutics. (shrink)
He began his negative case by attacking platonist theories, that is, theories identifying the universal as a separated form really distinct from the individuals it characterizes.3 His next target was so-called moderate realist theories, which identify the universal as a form that is really distinct but not separate from the individuals it characterizes.4 Finally, he turns to Scotist theories, which identify the universal as a form that is only formally distinct from the individuals it characterizes, neither really distinct nor separable (...) from them.5 Buridan’s discussion therefore follows a pattern similar to that found in William of Ockham, where the arguments against..

Murray MacBeath, in his essay ``Time's Square'', describes a fictitious scenariowhere various physical observations made by the participants would, he claims, invitethe interpretation that time for them is two-dimensional. In the present paper, however, Iargue that such observations come close to underdetermining the hypothesis of time's twodimensionality;for a rival hypothesis - that, under certain circumstances, the observationscan be explained in terms of the familiar time dilation effects predicted by special relativity- almost fits the evidence as well. That is, under certain (...) (albeit artificial) circumstances theworld can already behave almost as though it were temporally two-dimensional. (shrink)
The nanomedicine field is fast evolving toward complex, “active,” and interactive formulations. Like many emerging technologies, nanomedicine raises questions of how human subjects research (HSR) should be conducted and the adequacy of current oversight, as well as how to integrate concerns over occupational, bystander, and environmental exposures. The history of oversight for HSR investigating emerging technologies is a patchwork quilt without systematic justification of when ordinary oversight for HSR is enough versus when added oversight is warranted. Nanomedicine HSR provides an (...) occasion to think systematically about appropriate oversight, especially early in the evolution of a technology, when hazard and risk information may remain incomplete. This paper presents the consensus recommendations of a multidisciplinary, NIH-funded project group, to ensure a science-based and ethically informed approach to HSR issues in nanomedicine, and to integrate HSR analysis with analysis of occupational, bystander, and environmental concerns. We recommend creating two bodies, an interagency Human Subjects Research in Nanomedicine (HSR/N) Working Group and a Secretary's Advisory Committee on Nanomedicine (SAC/N). HSR/N and SAC/N should perform 3 primary functions: (1) analysis of the attributes and subsets of nanomedicine interventions that raise HSR challenges and current gaps in oversight; (2) providing advice to relevant agencies and institutional bodies on the HSR issues, as well as federal and federal-institutional coordination; and (3) gathering and analyzing information on HSR issues as they emerge in nanomedicine. HSR/N and SAC/N will create a home for HSR analysis and coordination in DHHS (the key agency for relevant HSR oversight), optimize federal and institutional approaches, and allow HSR review to evolve with greater knowledge about nanomedicine interventions and greater clarity about attributes of concern.

As levels of trust decrease and the necessity for trust increase in our society, we are increasingly driven toward the untoward, even disastrous, outcomes of the prisoner's dilemma. Yet despite the growing evidence that (re)building conditions of trust is increasingly mandatory in our era, modern moral philosophy (by default) and the social sciences (implicitly) legitimize an instrumental rationality which is the root problem. The greatest danger is that as conditions of trust are rationalized away through the progressive institutionalization of an (...) instrumental rationality, we are driven towards the most virulent form of the prisoner's paradox — ethical relativism and its nihilistic consequences.

The CDC's HIV screening recommendations for health care settings advocate abandoning two important autonomy protections: (1) pretest counseling and (2) the requirement that providers obtain affirmative agreement from patients prior to testing. The recommendations may violate the least infringement principle because there is insufficient evidence to conclude that abandoning pretest counseling or affirmative agreement requirements will further the CDC's stated public health goals.
Biodefense and emerging infectious disease animal research aims to avoid or ameliorate human disease, suffering, and death arising, or potentially arising, from natural outbreaks or intentional deployment of some of the world’s most dreaded pathogens. Top priority research goals include finding vaccines to prevent, diagnostic tools to detect, and medicines for smallpox, plague, ebola, anthrax, tularemia, and viral hemorrhagic fevers, among many other pathogens (National Institute of Allergy and Infectious Diseases [NIAID] priority pathogens). To this end, increased funding for conducting (...) research, developing research facilities, and purchasing (stockpiling) developed vaccines, diagnostic tools, and therapeutics .. (shrink)

Neither are Buridan’s credentials as a nominalist in doubt, although investigation into his precise relation to William of Ockham continues: he rejected all abstract entities, whether universals, common natures, the complexe significabile, or types above and beyond tokens; for Buridan, every thing which exists is a concrete individual. His anti-realism included an epistemological component as well, for Buridan (...) maintained that the source of all knowledge is experience. (shrink)
cause other than the very individual itself, and thus there is no ‘metaphysical’ problem of individuation at all—individuality, unlike generality, is primitive and needs no explanation. He supports this view in two ways. First, he argues that there are no nonindividual entities, whether existing in their own right or as metaphysical constituents either of things or in things, and hence that no real principle or cause of individuality (other than the individual itself) is required. Second, he offers a ‘semantic’ interpretation (...) of what appear to be metaphysical difficulties about individuality by recasting the issues in the formal mode, as issues within semantics, such as how a referring expression can pick out a single individual. Yet although there is no ‘metaphysical’ problem of individuation, Buridan discusses two associated problems at some length: the identity of individuals over time and the discernibility of individuals.

This paper identifies strands of reasoning underlying several theories of democratic authority. It shows why each of them fails to adequately explain or justify it. Yet, it does not claim ( per philosophical anarchism) that democratic authority cannot be justified. Furthermore, it sketches an argument for a perspective on the justification of democratic authority that would effectively respond to three problems not resolved by alternative theories—the problem of the expert, the problem of specificity, and the problem of deference. Successfully resolving (...) these problems is at least evidence for the viability of a justification of democratic authority. This perspective integrates procedural concerns with those about the quality of democratic outcomes. It shows that democratic authority, if there is such a thing, requires reliable democratic procedures as the only sort citizens could rationally accept. (shrink)

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

Economic theories of democratic legitimacy (discussed here as minimalist theories) have criticized deliberative accounts of democratic legitimacy on the grounds that they do not represent a practical possibility and that they create conditions that make actual democracies worse. It is not simply that they represent the wrong ideal. Rather, they are too idealistic – failing to show proper regard for the cognitive and moral limitations of persons and the depth of disagreement in democratic society. This article aims to show (1) (...) that the minimalist criterion of democratic legitimacy is self-defeating and (2) that even if there are minimal cognitive, moral, and social requirements for the possibility of practicable deliberative democracy, these limitations do not necessarily impose insuperable barriers for democratic deliberation as the normative basis of democratic legitimacy. Thus, the limiting facts do not dictate the structure of appropriate normative models of democracy in the way minimalists have supposed. (shrink)

I propose that an ill-appreciated contrast between the examples Socrates gives Meno, to show him how he ought to philosophize, is the key to understanding the Meno. I contend that Socrates prefers hisdefinitions of shape to his account of color because the former are concerned with what shape is, while the latter is concerned with how color comes to be. This contrast suggests that Plato intends ananalogous contrast between the (properly philosophical) way of inquiry that leads to Socrates’ definition of (...) knowledge as “true belief tied down with an account” and the (not properly philosophical) way of inquiry that leads to Socrates’ account of how knowledge comes to be, that is, the “theory of recollection.”.

We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose (...) unique challenges. First, tension regarding the use of human embryos may complicate the scientific development of safe and effective cell lines. Second, because human stem cells were not developed in the laboratory until 1998, few safety questions relating to human applications have been addressed in animal research. Third, preclinical and clinical testing of biologic agents, particularly those as inherently complex as mammalian cells, present formidable challenges, such as the need to develop suitable standardized assays and the difficulty of selecting appropriate patient populations for early phase trials. We recommend that scientists, policy makers, and the public discuss these issues responsibly, and further, that a national advisory committee to oversee human trials of cell therapies be established. **NB we did not reccommend a NAC, we think it might be appropriate**.

Contemporary Western culture is experiencing a heightened awareness of religious diversity. This article surveys a range of possible responses to such diversity, and distinguishes between responses that concern the salvation or moral transformation of persons (soteriological views) and those that concern the alethic or epistemic status of religious beliefs (doctrinal views). After providing a brief taxonomy of these positions and their possible relations to one another, the article focuses primarily on competing views about the truth and rationality of religious beliefs (...) (e.g., pluralism, exclusivism, and skepticism). Here a heavy emphasis is placed on arguments for and against the rationality and moral propriety of retaining one's religious beliefs in the face of disagreement. The article surveys some of the more prominent arguments from the literature on this topic and closes with suggestions for further research. (shrink)
There are two strands in Bourdieu's sociological writings. On the one hand, Bourdieu argues for a theoretical position one might term his "practical theory" which emphasizes virtuosic interactions between individuals. On the other hand, and most frequently, Bourdieu appeals to the concept of the habitus according to which society consists of objective structures and determined-and isolated-individuals. Although Bourdieu believes that the habitus is compatible with his practical theory and overcomes the impasse of objectivism and subjectivism in social theory, neither claim (...) is the case; the habitus is incompatible with his practical theory, and it retreats quickly into objectivism. However, Bourdieu's practical theory does offer a way out of the impasse of objectivism and subjectivism by focussing on the intersubjective interactions between individuals. (shrink)
Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn't have been instantiated. These views motivate Stalnaker's "two dimensional" account of the necessary a posteriori on which there is no single proposition that is both necessary and a posteriori. For a (metaphysically) necessary proposition is true in all (metaphysically) possible worlds. If there were necessary a posteriori propositions, (...) that would mean that there were propositions true in all possible worlds but which could only be known to be true by acquiring empirical evidence. Consider such a purported proposition P. The role of empirical evidence for establishing P's truth would have to be to rule out worlds in which P is false. If there were no such worlds to be ruled out, we would not require evidence for P. But by hypothesis, P is necessary and so true in all metaphysically possible worlds. And on Stalnaker's view, the metaphysically possible worlds are all the worlds there are. So there can be no proposition that is true in all possible worlds, but that we require evidence to know. In this way, the motivation for Stalnaker's two dimensional account of the necessary a posteriori rests on his denying that there are metaphysically impossible Worlds. I argue that given his view of what possible worlds are, Stalnaker has no principled reason for denying that there are metaphysically impossible worlds. If I am right, this undercuts Stalnaker's motivation for his two dimensional account of the necessary a posteriori. (shrink)
