William Uttal is concerned that in an effort to prove itself a hard science, psychology may have thrown away one of its most important methodological tools—a critical analysis of the fundamental assumptions that underlie day-to-day empirical research. In this book Uttal addresses the question of localization: whether psychological processes can be defined and isolated in a way that permits them to be associated with particular brain regions. New, noninvasive imaging technologies allow us to observe the brain while it is (...) actively engaged in mental activities. Uttal cautions, however, that the excitement of these new research tools can lead to a neuroreductionist wild goose chase. With more and more cognitive neuroscientific data forthcoming, it becomes critical to question their limitations as well as their potential. Uttal reviews the history of localization theory, presents the difficulties of defining cognitive processes, and examines the conceptual and technical difficulties that should make us cautious about falling victim to what may be a "neo-phrenological" fad.

A major philosophical mind in his day, William Paley wrote in a lucid style that made complex ideas more accessible to a wide readership. This work, first published in 1785, was based on the lectures he gave on moral philosophy at Christ's College, Cambridge. Cited in parliamentary debates and remaining on the syllabus at Cambridge into the twentieth century, it stands as one of the most influential texts to emerge from the Enlightenment period in Britain. An orthodox theologian, grounding (...) his utilitarian ethics in strong religious faith, Paley held notably progressive views on issues of toleration and the slave trade. His perspicuity prompted one contemporary to remark that the book 'presents a subject which has always been considered as harsh and difficult, in the most agreeable and intelligible form … we sit down to be informed of our duty, and are surprised to meet with amusement'.

William Tait is one of the most distinguished philosophers of mathematics of the last fifty years. This volume collects his most important published philosophical papers from the 1980's to the present. The articles cover a wide range of issues in the foundations and philosophy of mathematics, including some on historical figures ranging from Plato to Gdel.

Darwin's greatest accomplishment was to show how life might be explained as the result of natural selection. But does Darwin's theory mean that life was unintended? William A. Dembski argues that it does not. In this book Dembski extends his theory of intelligent design. Building on his earlier work in The Design Inference (Cambridge, 1998), he defends that life must be the product of intelligent design. Critics of Dembski's work have argued that evolutionary algorithms show that life can be (...) explained apart from intelligence. But by employing powerful recent results from the No Free Lunch Theory, Dembski addresses and decisively refutes such claims. As the leading proponent of intelligent design, Dembski reveals a designer capable of originating the complexity and specificity found throughout the cosmos. Scientists and theologians alike will find this book of interest as it brings the question of creation firmly into the realm of scientific debate. (shrink)

The degradation of modern sport--its commercialization, trivialization, widespread cheating, cult of athletic stars and celebrities, and manipulation by the media--has led to calls for its transformation. William J. Morgan constructs a critical theory of sport that shores up the weak arguments of past attempts and points a way forward to making sport more humane, compelling, and substantive. Drawing on the work of social theorists, Morgan challenges scholars and fans alike to explore new spaces in sport culture and imagine the (...) rich cultural and political possibilities to be found in the pastimes we follow with such passion.

While neuroscientists often characterize brain activity as representational, many philosophers have construed these accounts as just theorists’ glosses on the mechanism. Moreover, philosophical discussions commonly focus on finished accounts of explanation, not research in progress. I adopt a different perspective, considering how characterizations of neural activity as representational contributes to the development of mechanistic accounts, guiding the investigations neuroscientists pursue as they work from an initial proposal to a more detailed understanding of a mechanism. I develop one illustrative example involving (...) research on the information-processing mechanisms mammals employ in navigating their environments. This research was galvanized by the discovery in the 1970s of place cells in the hippocampus. This discovery prompted research in what the activity of these cells represents and how place representations figure in navigation. It also led to the discovery of a host of other types of neurons—grid cells, head-direction cells, boundary cells—that carry other types of spatial information and interact with place cells in the mechanism underlying spatial navigation. As I will try to make clear, the research is explicitly devoted to identifying representations and determining how they are constructed and used in an information processing mechanism. Construals of neural activity as representations are not mere glosses but are characterizations to which neuroscientists are committed in the development of their explanatory accounts. (shrink)

"This book, one of the most frequently cited works on Martin Heidegger in any language, belongs on any short list of classic studies of Continental philosophy. William J. Richardson explores the famous turn in Heidegger's thought after Being in Time and demonstrates how this transformation was radical without amounting to a simple contradiction of his earlier views." "In a full account of the evolution of Heidegger's work as a whole, Richardson provides a detailed, systematic, and illuminating account of both (...) divergences and fundamental continuities in Heidegger's philosophy, especially in light of recently published works. He demonstrates that the "thinking" of Being for the later Heidegger has exactly the same configuration as the radical phenomenology of the early Heidegger, once he has passed through the "turning" of his way." Including as a preface the letter that Heidegger wrote to Richardson and a new writer's preface and epilogue, the new edition of this valuable guide will be an essential resource for students and scholars for many years to come.

A fellow of Trinity College, Cambridge, and of the Royal Society, William Clifford (1845–79) made his reputation in applied mathematics, but his interests ranged far more widely, encompassing ethics, evolution, metaphysics and philosophy of mind. This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Volume (...) 2 shows Clifford's thorough engagement with scientific thought as a method for illuminating ethical and moral questions. Essays such as 'Body and Mind', 'On the Scientific Basis of Morals' and 'The Ethics of Belief' all variously demonstrate Clifford's core tenet: that beliefs - whether they guide human action or scientific enquiry - 'can never suffer from investigation'.

Discourse ethics represents an exciting new development in neo-Kantian moral theory. William Rehg offers an insightful introduction to its complex theorization by its major proponent, Jürgen Habermas, and demonstrates how discourse ethics allows one to overcome the principal criticisms that have been leveled against neo-Kantianism. Addressing both "commun-itarian" critics who argue that universalist conceptions of justice sever moral deliberation from community traditions, and feminist advocates of the "ethics of care" who stress the moral significance of caring for other individuals, (...) Rehg shows that discourse ethics combines impartiality with solidarity. He provides the first systematic reconstruction of Habermas's theory and explores its relationship to the work of such contemporary philosophers as Charles Taylor. His book articulates a bold alternative to the split between the "right" and the "good" in moral theory and will greatly interest philosophers, social and legal scholars, and political theorists.

In _Facing the Planetary_ William E. Connolly expands his influential work on the politics of pluralization, capitalism, fragility, and secularism to address the complexities of climate change and to complicate notions of the Anthropocene. Focusing on planetary processes—including the ocean conveyor, glacier flows, tectonic plates, and species evolution—he combines a critical understanding of capitalism with an appreciation of how such nonhuman systems periodically change on their own. Drawing upon scientists and intellectuals such as Lynn Margulis, Michael Benton, Alfred North (...) Whitehead, Anna Tsing, Mahatma Gandhi, Wangari Maathai, Pope Francis, Bruno Latour, and Naomi Klein, Connolly focuses on the gap between those regions creating the most climate change and those suffering most from it. He addresses the creative potential of a "politics of swarming" by which people in different regions and social positions coalesce to reshape dominant priorities. He also explores how those displaying spiritual affinities across differences in creed can energize a militant assemblage that is already underway. (shrink)

In Natural Ethical Facts William Casebeer argues that we can articulate a fully naturalized ethical theory using concepts from evolutionary biology and cognitive science, and that we can study moral cognition just as we study other forms of cognition. His goal is to show that we have "softly fixed" human natures, that these natures are evolved, and that our lives go well or badly depending on how we satisfy the functional demands of these natures. Natural Ethical Facts is a (...) comprehensive examination of what a plausible moral science would look like.Casebeer begins by discussing the nature of ethics and the possible relationship between science and ethics. He then addresses David Hume's naturalistic fallacy and G. E. Moore's open-question argument, drawing on the work of John Dewey and W. V. O. Quine. He then proposes a functional account of ethics, offering corresponding biological and moral descriptions. Discussing in detail the neural correlates of moral cognition, he argues that neural networks can be used to model ethical function. He then discusses the impact his views of moral epistemology and ontology will have on traditional ethical theory and moral education, concluding that there is room for other moral theories as long as they take into consideration the functional aspect of ethics; the pragmatic neo-Aristotelian virtue theory he proposes thus serves as a moral "big tent." Finally, he addresses objections to ethical naturalism that may arise, and calls for a reconciliation of the sciences and the humanities. "Living well," Casebeer writes, "depends upon reweaving our ethical theories into the warp and woof of our scientific heritage, attending to the myriad consequences such a project will have for the way we live our lives and the manner in which we structure our collective moral institutions.".

Several philosophers of science and metaphysicians claim that the dispositional properties of fundamental particles, such as the mass, charge, and spin of electrons, are ungrounded in any further properties. It is assumed by those making this argument that such properties are intrinsic, and thus if they are grounded at all they must be grounded intrinsically. However, this paper advances an argument, with one empirical premise and one metaphysical premise, for the claim that mass is extrinsically grounded and is thus an (...) extrinsic disposition. Although the argument concerns mass characterized as a disposition, it applies equally well whether mass is a categorical or dispositional property; however, the dispositional nature of mass is relevant to some important objections and implications discussed.

Contemporary science presents us with the remarkable theory that the universe began to exist about fifteen billion years ago with a cataclysmic explosion called "the Big Bang." The question of whether Big Bang cosmology supports theism or atheism has long been a matter of discussion among the general public and in popular science books, but has received scant attention from philosophers. This book sets out to fill this gap by means of a sustained debate between two philosophers, William Lane (...) Craig and Quentin Smith, who defend opposing positions. Craig argues that the Big Bang that began the universe was created by God, while Smith argues that the Big Bang has no cause. Alternating chapters by the two philosophers criticize and attempt to refute preceding arguments. Their arguments are based on Einstein's theory of relativity and include a discussion of the new quantum cosmology recently developed by Stephen Hawking and popularized in A Brief History of Time.

Philosophy has been characterized (e.g., by Benson Mates) as a field whose problems are unsolvable. This has often been taken to mean that there can be no progress in philosophy as there is in mathematics or science. The nature of problems and solutions is considered, and it is argued that solutions are always parts of theories, hence that acceptance of a solution requires commitment to a theory (as suggested by William Perry's scheme of cognitive development). Progress can be had (...) in philosophy in the same way as in mathematics and science by knowing what commitments are needed for solutions. Similar views of Rescher and Castañeda are discussed.

The problem of Galileo's logical methodology has long interested scholars. In this volume William A. Wallace offers a solution that is completely unexpected, yet backed by convincing documentary evidence. His analysis starts with an early notebook Galileo wrote at Pisa, appropriating a Jesuit professor's exposition of the Posterior Analystics of Aristotle, and ends with one of the last letters Galileo wrote, stating that in logic he has been a Peripatetic all his life. Wallace's detective work unearths the complete logic (...) course from which the notebook was excerpted, then proceeds to show how its terminology and methodology continue to surface in Galileo's later writings in which he founds his new sciences of the heavens and of local motion. The result is a tour de force that commends itself not only to Galileo's scholars and to logicians, philosophers, and historians, but to anyone interested in the epistemic roots of modern science.

Systems biology has provided new resources for discovering and reasoning about mechanisms. In addition to generating databases of large bodies of data, systems biologists have introduced platforms such as Cytoscape to represent protein–protein interactions, gene interactions, and other data in networks. Networks are inherently flat structures. One can identify clusters of highly connected nodes, but network representations do not represent these clusters as at a higher level than their constituents. Mechanisms, however, are hierarchically organized: they can be decomposed into their (...) parts and their activities can be decomposed into component operations. A potent bridge between flat networks and hierarchical mechanisms is provided by biological ontologies, both those curated by hand such as Gene Ontology and those extracted directly from databases such as Network Extracted Ontology. I examine several examples in which by applying ontologies to networks, systems biologists generate new hypotheses about mechanisms and characterize these novel strategies for developing mechanistic explanations.

This article first addresses the question of “why” we teach business ethics. Our answer to “why” provides both a response to those who oppose business ethics courses and a direction for course content. We believe a solid, comprehensive course in business ethics should address not only moral philosophy, ethical dilemmas, and corporate social responsibility – the traditional pillars of the disciple – but also additional areas necessary to make sense of the goings-on in the business world and in the news. (...) These “new pillars,” that we advocate include moral psychology, organizational design and behavior, motivational theory, and a unit on how society, business, and law interact. This last unit builds upon the work of Francis P. McHugh (1988) who urged an integration of “disciplines related to business ethics.” Our seventh pillar would encompass an integration of law, socio-political theory, and policy to demonstrate how business helps construct its own regulatory framework. The concluding recommendation is for a comprehensive “Seven Pillars” of business ethics approach. (shrink)

I oppose the popular view that the phenomenal character of perceptual experience consists in the subject's representing the (putative) perceived object as being so-and-so. The account of perceptual experience I favor instead is a version of the "Theory of Appearing" that takes it to be a matter of the perceived object's appearing to one as so-and-so, where this does not mean that the subject takes or believes it to be so-and-so. This plays no part in my criticisms of Representationalism. I (...) mention it only to be up front as to where I stand. My criticism of the Representationalist position is in sections. (1) There is no sufficient reason for positing a representative function for perceptual experience. It doesn't seem on the face of it to be that, and nothing serves in place of such seeming. (2) Even if it did have such a function, it doesn't have the conceptual resources to represent a state of affairs. (3) Even if it did, it is not suited to represent, e.g., a physical property of color. (4) Finally, even if I am wrong about the first three points, it is still impossible for the phenomenal character of the perceptual experience to consist in it's representing what it does. My central argument for this central claim of the paper is that it is metaphysically, de re possible that one have a certain perceptual experience without it's presenting any state of affairs. And since all identities hold necessarily, this identity claim fails. (shrink)

A climactic piece in the controversy between rationalists & the advocates of sentiment.

“The object of this book,” writes William C. Dowling in his preface, “is to make the key concepts of Paul Ricoeur’s _Time and Narrative_ available to readers who might have felt bewildered by the twists and turns of its argument.” The sources of puzzlement are, he notes, many. For some, it is Ricoeur’s famously indirect style of presentation, in which the polarities of argument and exegesis seem so often and so suddenly to have reversed themselves. For others, it is (...) the extraordinary intellectual range of Ricoeur’s argument, drawing on traditions as distant from each other as Heideggerian existentialism, French structuralism, and Anglo-American analytic philosophy. Yet beneath the labyrinthian surface of Ricoeur’s _Temps et récit_, Dowling reveals a single extended argument that, though developed unsystematically, is meant to be understood in systematic terms. __Ricoeur on Time and Narrative_ _presents that argument in clear and concise terms, in a way that will be enlightening both to readers new to Ricoeur and those who may have felt themselves adrift in the complexities of _Temps et récit,_ Ricoeur’s last major philosophical work. Dowling divides his discussion into six chapters, all closely involved with specific arguments in _Temps et récit_: on mimesis, time, narrativity, semantics of action, poetics of history, and poetics of fiction. Additionally, Dowling provides a preface that lays out the French intellectual context of Ricoeur's philosophical method. An appendix presents his English translation of a personal interview in which Ricoeur, having completed _Time and Narrative, _looks back over his long career as an internationally renowned philosopher. __Ricoeur on Time and Narrative___ _communicates to readers the intellectual excitement of following Ricoeur’s dismantling of established theories and arguments—Aristotle and Augustine and Husserl on time, Frye and Greimas on narrative structure, Arthur Danto and Louis O. Mink on the nature of historical explanation—while coming to see how, under the pressure of Ricoeur’s analysis, these ideas are reconstituted and revealed in a new set of relations to one another. "The scholarship in William C. Dowling's __Ricoeur on Time and Narrative____ __is impeccable; Dowling knows Ricoeur inside out. He highlights Ricoeur's most important arguments, presents them in a limpid, concise language, and links them to the relevant nineteenth- and twentieth-century philosophical developments. Dowling's book provides us with a lucid, intelligible version of Ricoeur's major work, one that will be of considerable significance to philosophers, historians, and literary theorists." —_Thomas Pavel, Gordon J. Laing Distinguished Service Professor of French Literature, and the Committee on Social Thought, University of Chicago_ "William C. Dowling's __Ricoeur on Time and Narrative___ _is a subtle and remarkably well-sustained piece of work. It provides a detailed introduction to a major work of philosophy and narrative theory—already a considerable achievement, given the difficulty of Ricoeur's text. However, Dowling also shows us, sometimes explicitly, sometimes simply through the way he conducts his argument, why we should bother with Ricoeur—what we have to gain from knowing him better than we do, however well we may think we know him." —_Michael Wood, Charles Barnwell Straut Class of 1923 Professor of English and Comparative Literature, Princeton University _.

There is an ongoing debate about the value of virtual friendship. In contrast to previous authorships, this paper argues that virtual friendship can have independent value.

It is argued that Heidegger should be seen as something of a Kantian Idealist. Like Kant, Heidegger distinguishes two standpoints (transcendental and empirical) which we can occupy when we ask the question whether natural things depend on us. He agrees with Kant that from the empirical or human standpoint we are justified in saying that natural things do not depend on us. But in contrast with Kant, Heidegger argues that from the transcendental standpoint we can say neither that natural things (...) do depend on us, nor that they do not. His reasons for saying this, however, represent an attempt to rework both Kant's temporal idealism and his temporal interpretation of the concept of an object (which shows up in Heidegger as a temporal interpretation of being). Heidegger suggests that Kant was led astray into a transcendental idealism about natural entities, because he did not understand the implications of transcendental idealism about being. (shrink)

Research in many fields of biology has been extremely successful in decomposing biological mechanisms to discover their parts and operations. It often remains a significant challenge for scientists to recompose these mechanisms to understand how they function as wholes and interact with the environments around them. This is true of the eukaryotic cell. Although initially identified in nineteenth-century cell theory as the fundamental unit of organisms, researchers soon learned how to decompose it into its organelles and chemical constituents and have (...) been highly successful in understanding how these carry out many operations important to life. The emphasis on decomposition is particularly evident in modern cell biology, which for the most part has viewed the cell as merely a locus of the mechanisms responsible for vital phenomena. The cell, however, is also an integrated system and for some explanatory purposes it is essential to recompose it and understand it as an organized whole. I illustrate both the virtues of decomposition (treating the cell as a locus) and recomposition (treating the cell as an object) with recent work on circadian rhythms. Circadian researchers have both identified critical intracellular operations that maintain endogenous oscillations and have also addressed the integration of cells into multicellular systems in which cells constitute units.

Explanations of biological phenomena such as cell division, protein synthesis or circadian rhythms commonly take the form of models of the responsible mechanisms. Recently philosophers of science have attempted to analyze this practice, presenting mechanisms as organized collections of parts performing operations that together produce the phenomenon. But in some cases what researchers seek to explain is not a general phenomenon, but a specific feature of a more fine-grained phenomenon. In some of these cases, it is not the model of (...) the mechanism that performs the explanatory work. I consider a case in which the investigator offered an abstract representation of a fine-grained phenomenon to show why in had the feature in question. I consider a second case in which a researcher abstracted from the mechanism to identify a design principle that explains why the functioning mechanism exhibits a specific feature. (shrink)

This 2 part book, originally published in 1890, was written to help students of morals comprehend the significance of morals. The questions with which an historian of morals is chiefly concerned are the changes that have taken place in the moral standard and in the moral type, the degrees in which, in different ages, recognised virtues have been enjoined and practiced and the relative importance that in different ages has been attached to different virtues.

This paper defends the view that a belief to the effect that the believer is currently in some conscious state is "self-Warranted," in the sense that what warrants it is simply its being a belief of that sort.

In the course of the discussion, Various modes of immediate (...) justification and various types of "epistemic immunities" are distinguished. It is contended that principles of justification are to be evaluated in terms of whether the beliefs they approve are likely to be correct. (shrink)

Among the notions of levels invoked in accounts of biological phenomena, I focus on two: levels of production mechanisms and levels of control mechanisms. I argue that these two notions of level exhibit different characteristics: production mechanisms are organized hierarchically while control mechanisms are often organized heterarchically. I illustrate the differences in these modes of organization by examining production and control mechanisms involved in cell division in Escherichia coli and in circulation of blood in mammals. I conclude by exploring how (...) these two notions of levels can be integrated by adopting a perspective in which organisms are autonomous systems maintaining themselves far from equilibrium.
