In Toward a Pragmatist Sociology, Robert Dunn explores the relationship between the ideas of philosopher and educator John Dewey and those of sociologist C. Wright Mills in order to provide a philosophical and theoretical foundation for the development of a critical and public sociology. Dunn recovers an intellectual and conceptual framework for transforming sociology into a more substantive, comprehensive, and socially useful discipline. Toward a Pragmatist Sociology argues that Dewey and Mills shared a common vision of a (...) relevant, critical, public sociology dedicated to the solution of societal problems. Dunn investigates the past and present state of the discipline, critiquing its dominant tendencies, and offering historical examples of alternatives to conventional sociological approaches. By stressing the similar intellectual and moral visions of both men, Toward a Pragmatist Sociology provides an original treatment of two important American thinkers whose work offers a conception and model of a sociology with a sense of moral and political purpose and public relevance. It should liberate future sociologists and others to regard the discipline as not only a science but an intellectual, moral, and political enterprise. (shrink)

Enormous and significant progress has been made in the important areas of entanglement, quantum computing and harnessing energy from the vacuum, which includes a sound theoretical basis, using the Einstein-Sachs theories to develop an anti-symmetric general relativity (AGR) approach to a higher topology O(3) electrodynamics. These developments also lead to the application of the Aharonov-Bohm effect and the Yang-Mills theory to the higher topology O(3) electrodynamics, as well as a deeper understanding and appreciation of these effects and their impact (...) on modern physics. The door is now open for the further development and unification of physics, including the gravitational, electromagnetic, weak, and strong forces, using the AGR approach. (shrink)

"Understanding Empiricism" is an introduction to empiricism and the empiricist tradition in philosophy. The book presents empiricism as a philosophical outlook that unites several philosophers and discusses the most important philosophical issues bearing on the subject, while maintaining enough distance from, say, the intricacies of Locke, Berkeley, Hume scholarship to allow students to gain a clear overview of empiricism without being lost in the details of the exegetical disputes surrounding particular philosophers. Written for students the book can serve both as (...) an introduction to current problems in the theory of knowledge as well as a comprehensive survey of the history of empiricist ideas. The book begins by distinguishing between the epistemological and psychological/causal versions of empiricism, showing that it is the former that is of primary interest to philosophers. The next three chapters, on Locke, Berkeley, Hume respectively, provide an introduction to the main protagonists in the British empiricist tradition from this perspective. The book then examines more contemporary material including the ideas of Sellars, foundations and coherence theories, the rejection of the a priori by Mill, Peirce and Quine, scepticism and, finally, the status of religious belief within empiricism. Particular attention is paid to criticisms of empiricism, such as Leibniz's criticisms of Locke on innatism and Frege's objections to Mill on mathematics. The discussions are kept at an introductory level throughout to help students to locate the principles of empiricism in relation to modern philosophy. (shrink)

Developments over the past four decades have secured Immanuel Kant’s status as being for contemporary philosophers what the sea was for Swinburne: the great, gray mother of us all. And Kant mattered as much for the classical American pragmatists as he does for us today. But we look back at that sepia-toned age across an extended period during which Anglophone philosophy largely wrote Kant out of its canon. The founding ideology of Bertrand Russell and G.E. Moore, articulating the rationale and (...) fighting faith for the rising tide of analytic philosophy, was forged in a recoil from the perceived defects of a British idealism inspired by Hegel. Mindful of the massive debt evidently and self-avowedly owed by Hegel to Kant, and putting aside neo-Kantian readings of Kant as an empiricist philosopher of science that cast him in a light they would have found more favorable, Russell and Moore diagnosed the idealist rot as having set in already with Kant. For them, and for many of their followers down through the years, the progressive current in philosophy should be seen to have run directly from Locke, Leibniz, and Hume, to Mill and Frege, without any dangerous diversion into the oxbow of German idealism.

In the 19th century it was widely believed that scientific experiments on social issues were not, and never would be, feasible. Not only was social behaviour unpredictable in principle, but subjecting people to experimentation would be immoral. Although Comte, J. S. Mill, C. G. Lewis, and Herbert Spencer all argued to this conclusion, they also believed that natural innovations in society provided an adequate sub stitute for planned experiments. The question to be examined here is how such beliefs came to (...) be held and why they were never tested. (shrink)

ABSTRACT:Neuroethics, the study of the cognitive and neural mechanisms underlying ethical decision-making, is a growing field of study. In this review, we identify and discuss four themes emerging from neuroethics research. First, ethical decision-making appears to be distinct from other types of decision-making processes. Second, ethical decision-making entails more than just conscious reasoning. Third, emotion plays a critical role in ethical decision-making, at least under certain circumstances. Lastly, normative approaches to morality have distinct, underlying neural mechanisms. On the basis of (...) these themes, we draw implications for research in business ethics and the practice of ethics training. (shrink)

Theoretical explication of a growing body of empirical data on consciousness-related anomalous phenomena is unlikely to be achieved in terms of known physical processes. Rather, it will first be necessary to formulate the basic role of consciousness in the definition of reality before such anomalous experience can adequately be represented. This paper takes the position that reality is constituted only in the interaction of consciousness with its environment, and therefore that any scheme of conceptual organization developed to represent that reality (...) must reflect the processes of consciousness as well as those of its environment. In this spirit, the concepts and formalisms of elementary quantum mechanics, as originally proposed to explain anomalous atomic-scale physical phenomena, are appropriated via metaphor to represent the general characteristics of consciousness interacting with any environment. More specifically, if consciousness is represented by a quantum mechanical wave function, and its environment by an appropriate potential profile, Schrödinger wave mechanics defines eigenfunctions and eigenvalues that can be associated with the cognitive and emotional experiences of that consciousness in that environment. To articulate this metaphor it is necessary to associate certain aspects of the formalism, such as the coordinate system, the quantum numbers, and even the metric itself, with various impressionistic descriptors of consciousness, such as its intensity, perspective, approach/avoidance attitude, balance between cognitive and emotional activity, and receptive/assertive disposition. With these established, a number of the generic features of quantum mechanics, such as the wave/particle duality, and the uncertainty, indistinguishability, and exclusion principles, display metaphoric relevance to familiar individual and collective experiences. Similarly, such traditional quantum theoretic exercises as the central force field and atomic structure, covalent molecular bonds, barrier penetration, and quantum statistical collective behavior become useful analogies for representation of a variety of consciousness experiences, both normal and anomalous, and for the design of experiments to study these systematically.

How do thought and language manage to be 'about' aspects of the world? J. Robert G. Williams investigates how representation arises out of a fundamentally non-representational world, showing the explanatory relations between the representational properties of language, of thought, and of perception and intention.

Natural selection is commonly interpreted as the fundamental mechanism of evolution. Questions about how selection theory can claim to be the all-sufficient explanation of evolution often go unanswered by today's neo-Darwinists, perhaps for fear that any criticism of the evolutionary paradigm will encourage creationists and proponents of intelligent design.In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as natural experiments, are independent of (...) natural selection; indeed, he suggests, natural selection may get in the way of evolution. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation causes evolution, and that these phenomena are environmental as well as organismal.After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Based on this evidence of causation, he proposes some working hypotheses, examining mechanisms and processes common to all three arenas, and arrives at a theoretical framework that accounts for generative mechanisms and emergent qualities. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection. (shrink)

The dominant model for interpreting brain imaging experiments assumes that the brain is organized to support mental processes that control behavior. However functional neuroimaging experiments, particularly of cognitive tasks, have not shown a high level of reproducibility and localization. This lack of clear functional segregation has been blamed on limitations in imaging technology and non linearity and regional overlap in how the brain implements these processes. However the validity of the underlying cognitive models used to describe the brain have rarely (...) been questioned or directly tested against imaging results. We propose an alternative model of brain function which correlates observed human behavior directly with measured brain activity without assumptions about intervening cognitive processes, that we term the Non-Cognitive Behavioral Model (NBM). Our model derives from Behavioral Psychology but is extended to include brain activations in addition to behavior as an observable. A further extension is the role of neuroplasticity as opposed to innate cognitive processes in the development of the brains support of cognitive behavior. Applications of NBM to neuroimaging studies are described and contrasted with the standard methodology which we refer to as the Standard Cognitive Model (SCM). In one application, the NBM correctly predicted the global, total energy consumption as the brain parameter that best correlates with a person being in the state of consciousness, a correlation missed by studies using the SCM due to its assumption that global activity does not support cognitive processes. Neuroplasticity is shown to provide a natural explanation of findings that object recognition activating the fusiform facial area comes from expertise through raining as opposed to the SCM explanation of an innate cognitive process specialized for face recognition. The conclusions are generalized to explain the poor reproducibility of cognitive processes reported in functional neuroimaging and to suggest how such studies can be used to better explain how the brain supports behavior.

The 3Rs, or the replacement, reduction, and refinement of animal research, are widely accepted as the best approach to maximizing high-quality science while ensuring the highest standard of ethical consideration is applied in regulating the use of animals in scientific procedures. This contrasts with the muted scientific interest in the 3Rs when they were first proposed in The Principles of Humane Experimental Technique. Indeed, the relative success of the 3Rs has done little to encourage engagement with their original text, which (...) remains little read and out of print. By adopting a historical perspective, this article argues that one explanation for this disjunction may be found in another, more celebrated, event of 1959: C. P. Snow’s Rede lecture on The Two Cultures. The moral outlook of The Principles of Humane Experimental Technique derived from an earlier ethos wherein humanistic and scientific values occupied a shared culture. While the synthetic style of The Principles has hindered its readership, this article concludes that there is value to recovering the notion that the humanities and social sciences can contribute to the improvement of animal research.

The principles of the 3Rs—replacement, refinement, and reduction—strongly shape discussion of methods for performing more humane animal research and the regulation of this contested area of technoscience. This special issue looks back to the origins of the 3Rs principles through five papers that explore how it is enacted and challenged in practice and that develop critical considerations about its future. Three themes connect the papers in this special issue. These are the multiplicity of roles enacted by those who use and (...) care for animals in research, the distribution of “feelings that matter” across species and spaces of laboratory animal practice, and the growing importance of “cultures of care” in animal research.

Seeking a scientific basis for understanding and treating mental illness, and inspired by the work of Ivan Pavlov, American physiologists, psychiatrists and psychologists in the 1920s turned to nonhuman animals. This paper examines how new constructs such as “experimental neurosis” emerged as tools to enable psychiatric comparison across species. From 1923 to 1962, the Cornell “Behavior Farm” was a leading interdisciplinary research center pioneering novel techniques to experimentally study nonhuman psychopathology. Led by the psychobiologist Howard Liddell, work at the Behavior (...) Farm formed part of an ambitious program to develop new preventative and therapeutic techniques and bring psychiatry into closer relations with physiology and medicine. At the heart of Liddell’s activities were a range of nonhuman animals, including pigs, sheep, goats and dogs, each serving as a proxy for human patients. We examine how Pavlov’s conceptualization of ‘experimental neurosis’ was used by Liddell to facilitate comparison across species and communication between researchers and clinicians. Our close reading of his experimental system demonstrates how unexpected animal behaviors and emotions were transformed into experimental virtues. However, to successfully translate such behaviors from the animal laboratory into the field of human psychopathology, Liddell increasingly reached beyond, and, in effect, redefined, the Pavlovian method to make it compatible and compliant with an ethological approach to the animal laboratory. We show how the resultant Behavior Farm served as a productive “hybrid” place, containing elements of experiment and observation, laboratory and field. It was through the building of close and more naturalistic relationships with animals over extended periods of time, both normal and pathological, and within and outside of the experimental space, that Liddell could understand, manage, and make useful the myriad behavioral complexities that emerged from the life histories of experimental animals, the researchers who worked with them, and their shared relationships to the wider physical and social environments.

Culp (1994) provides a defense for a form of experimental reasoning entitled 'robustness'. Her strategy is to examine a recent episode in experimental microbiology--the case of the mistaken discovery of a bacterial organelle called a 'mesosome'--with an eye to showing how experimenters effectively used robust experimental reasoning (or could have used robust reasoning) to refute the existence of the mesosome. My plan is to criticize Culp's assessment of the mesosome episode and to cast doubt on the epistemic significance of robustness. (...) In turn, I present a different account of the experimental reasoning microbiologists used in arriving at the conclusion that mesosomes are artifacts. I call this form of reasoning 'reliable process reasoning', and close the paper with a brief discussion of how experimental microbiologists justify the claim that an experimental process is reliable.

It is claimed that 'Do x!' means 'Then you will do x'. Answering a "Why?" question concerning the former may take either of two forms, viz., 'Because --' or 'If you wish to --'. The second answer completes the truncated hypothetical. "Ought" sentences are treated as a species of imperatives involving universality in the "if" clause ('If anyone wished to --'). Moral "ought" sentences involve a double universality, viz., the one mentioned above and universality connecting the action with social harmony (...)

The goal of this paper is to defend the claim that there is such a thing as direct perception, where by ‘direct perception’ I mean perception unmediated by theorizing or concepts. The basis for my defense is a general philosophic perspective which I call ‘empiricist philosophy’. In brief, empiricist philosophy (as I have defined it) is untenable without the occurrence of direct perception. It is untenable without direct perception because, otherwise, one can't escape the hermeneutic circle, as this phrase is (...) used in van Fraassen (1980). The bulk of the paper is devoted to defending my belief in direct perception against various objections that can be posed against it. I discuss various anticipations of my view found in the literature, eventually focusing on Ian Hacking's related conception of `entity realism' (Hacking 1983). Hacking has been criticized by a number of philosophers and my plan is to respond to these criticisms on behalf of entity realism (or more precisely on behalf of the claim that direct perception is a reality) and to then respond to other possible criticisms that can be launched against direct perception.

In 1942 a coalition of twenty scientific societies formed the Conference on the Supply of Experimental Animals in an attempt to pressure the Medical Research Council to accept responsibility for the provision of standardised experimental animals in Britain. The practice of animal experimentation was subject to State regulation under the Cruelty to Animals Act of 1876, but no provision existed for the provision of animals for experimental use. Consequently, day-to-day laboratory work was reliant on a commercial small animal market which (...) had emerged to sustain the hobby of animal fancying. This paper explores how difficulties encountered in experimental practice within the laboratory led to the problematisation of biomedical science’s reliance upon a commercial market for animals during the inter-war period. This is shown to have produced a crisis within animal reliant experimental science in the early 1940s which enabled the left-wing Association of Scientific Workers to cast science’s reliance on a free market as economically inefficient and a threat to the reliability of British research. It is argued that the development of standard experimental animals in Britain was, therefore, embedded within the wider cultural, societal, political and economic national context of the time.

ABSTRACT In the context of the COVID-19 pandemic, leaders are facing an ethical dilemma and a tense tradeoff between employees’ health and economic performance. From the perspective of employees’ perceptions of the work situation, this study examines the way ethical leadership enhances employee creativity during the COVID-19 pandemic by using leader-member exchange and organizational ethical climate as mediators. The sample included 308 supervisor-employee pairs from 20 high-tech companies in eight provincial regions of China. Structural equation modeling was used to test (...) the proposed hypotheses. Results indicate that ethical leadership can significantly enhance employee creativity through the fully mediating roles of employees’ perceptions of leader-member exchange and organizational ethical climate. Moreover, leader-member exchange affects employee creativity directly as well as indirectly through the mediating role of organizational ethical climate. This study offers insights into the process linking ethical leadership to employee creativity and provides practical suggestions on ways of enhancing employee creativity in situations like the COVID-19 pandemic crisis.

In 1993, an astonishing discovery was made at a tomb in Guodian in Hubei province. Written on strips of bamboo that have miraculously survived intact since 300 B.C., the "Guodian Laozi," is by far the earliest version of the _Tao Te Ching_ ever unearthed. Students of ancient Chinese civilization proclaimed the text a decisive breakthrough in the understanding of this famous text: it provides the most conclusive evidence to date that the text was the work of multiple authors and editors (...) over hundreds of years, rather than the achievement of a single individual writing during the time of Confucius. Robert Henricks now presents the first English translation of the "bamboo slip Laozi." Differing substantially from other versions we have of the text, the Guodian Laozi provides us with clues on how and when the text came into being. As Henricks's translation shows, many chapters are missing in this form of the text, and some chapters remain incomplete. All of this seems to suggest that the _Tao Te Ching_ was not yet "complete" when these slips were copied. In his translation, Henricks focuses attention on lines in each of the chapters that vary from readings in other editions. In addition, he shows how the sequence of chapters in this form of the text is totally unrelated to the sequence readers commonly see in the "standard" form of the text, i.e., in other translations. Here are just a few of the noteworthy features of this new _Tao Te Ching:_ • A lucid introduction to the Guodian Laozi, offering background on the archaeological interpretation of the discovery • Line-by-line comparisons of the Guodian Laozi against the Mawangdui and Wang Bi editions • Extensive notes on each chapter describing the unique elements of the Guodian Laozi in comparison with other versions • Transcriptions for each chapter, noting both the ancient and modern form of the characters in the chapter • An appendix featuring the official biography of Laozi written by Sima Qian, the Grand Historian of China, as well as Henricks's commentary and notes on this biography This groundbreaking work will lead to a reassessment of the history and significance of this well-known and critical work as well as a reevaluation of the role it played in the development of Taoism in early China.

This original new work takes a sharply focused look at Berkeley's ontology and provides a fuller understanding of the relationship between, on the one hand, Berkeley's nominalism and antiabstractionism and, on the other, his principal arguments for idealism and his attempts to square his idealism with common sense. Drawing heavily on detailed textual analysis, historical context, and careful examination of the work of other scholars, Muehlmann challenges, modifies, rejects, and exploits some well-established interpretations of Berkeley's philosophy.

The conjecture that international system structure determines war propensity has met with mixed results in past theory in political science. This question is reexamined within the context of a dynamic model of inter-nation hostile behavior. System structure is defined in terms of the degrees of grievance, fear, etc., among nations and also in terms of the qualitative patterns of hostile behavior that are possible. Propensity for war is measured in terms of the likelihood of progress to war within a given (...) class of hostile behaviors. Then the dynamic model is used to analyze in detail and interpret the relationship between system structure and war propensity. (shrink)

The ‘musca depicta’ trope is well known to art historians, with a history going back to Pliny. It flourished in the Renaissance, but in eighteenth-century England the meaning of the trope was altered greatly when employed in popular culture, both in live theatrical presentations (by George Alexander Stevens) and in published poetry (by James Robertson, comedian of York). Originally, the trope signalled the virtuosity of the painter, who was able to fool the eye by depicting flies so real that the (...) viewer attempted to shoo them off the picture. However, in the hands of Stevens and Robertson, that bit of theatre was turned on its head, as the supposed connoisseur engaged in a harsh criticism of a painting is startled when a fly that he thinks poorly depicted suddenly flies off the canvas, thereby rendering the connoisseur a satiric target.

Frequent lateral genetic transfer undermines the existence of a unique “tree of life” that relates all organisms. Vertical inheritance is nonetheless of vital interest in the study of microbial evolution, and knowing the “tree of cells” can yield insights into ecological continuity, the rates of change of different cellular characters, and the evolutionary plasticity of genomes. Notwithstanding within-species recombination, the relationships most frequently recovered from genomic data at shallow to moderate taxonomic depths are likely to reflect cellular inheritance. At the (...) same time, it is clear that several types of ‘average signals’ from whole genomes can be highly misleading, and the existence of a central tendency must not be taken as prima facie evidence of vertical descent. Phylogenetic networks offer an attractive solution, since they can be formulated in ways that mitigate the misleading aspects of hybrid evolutionary signals in genomes. But the connections in a network typically show genetic relatedness without distinguishing between vertical and lateral inheritance of genetic material. The solution may lie in a compromise between strict tree-thinking and network paradigms: build a phylogenetic network, but identify the set of connections in the network that are potentially due to vertical descent. Even if a single tree cannot be unambiguously identified, choosing a subnetwork of putative vertical connections can still lead to drastic reductions in the set of candidate vertical hypotheses.
