We face reality presented with the data of conscious experience and nothing else. The project of early modern philosophy was to build a complete theory of the world from this starting point, with no cheating. Crucial to this starting point is the data of conscious sensory experience – sense data. Attempts to avoid this project often argue that the very idea of sense data is confused. But the sense-data way of talking, the sense-data language, can be freed from every blemish (...) using ideas from contemporary metaontology. We can adopt a sense-data framework that vindicates the traditional claims of sense-data theories and leads to plausible theories of perception and color. We can, we should, and in a sense, we must. Yet when we do, we face the traditional problem of external world skepticism, head-on. The real challenge of skepticism is forced upon us; it cannot honestly be avoided using externalist tricks, burden of proof shifting, or other razzle dazzle. But the challenge can be met: we are rational to posit the external world as the best explanation of the many synchronic and diachronic patterns over our sense-data. This paper argues for all of these points and ends with a plea for analytic empiricism – a traditional sense-data version of empiricism that uses all of the tools of analytic philosophy while avoiding the more questionable doctrines of the Vienna Circle (phenomenalism, verificationism). Analytic empiricism is our last best hope for completing the great philosophical project of early modern philosophy. (shrink)

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

In this article, I show how Bruschi’s Le matérialisme politique de Louis Althusser offers, against all attempts conjure up a self-generating general theory of history, a reconstruction of Althusser’s work that shows how its systematicity relies upon the unfinished, incomplete and provisional character of scientific research, always subject to constant rectification. I then claim that, from the conceptualisa-tion of the reproduction of the mode of production as dependent upon the singularity of the con-juncture, to the theorisation of the encounter as (...) the source of historical necessity, this constant re-working is crucial to Althusser’s ability to grasp the reality of class struggle.

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism (...) as a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions (...) are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed. (shrink)

Marxism's collapse in the twentieth century profoundly altered the style and substance of Western European radical thought. To build a more robust form of democratic theory and action, prominent theorists moved to reject revolution, abandon class for more fragmented models of social action, and elevate the political over the social. Acknowledging the constructedness of society and politics, they chose the "symbolic" as a concept powerful enough to reinvent leftist thought outside a Marxist framework. Following Maurice Merleau-Ponty's Adventures of the Dialectic, (...) which reassessed philosophical Marxism at mid century, Warren Breckman critically revisits these thrilling experiments in the aftermath of Marxism. The post-Marxist idea of the symbolic is dynamic and complex, uncannily echoing the early German Romantics, who first advanced a modern conception of symbolism and the symbolic. Hegel and Marx denounced the Romantics for their otherworldly and nebulous posture, yet post-Marxist thinkers appreciated the rich potential of the ambiguities and paradoxes the Romantics first recognized. Mapping different ideas of the symbolic among contemporary thinkers, Breckman traces a fascinating reflection of Romantic themes and resonances, and he explores in depth the effort to reconcile a radical and democratic political agenda with a politics that does not privilege materialist understandings of the social. Engaging with the work of Claude Lévi-Strauss, Cornelius Castoriadis, Claude Lefort, Marcel Gauchet, Ernesto Laclau, Chantal Mouffe, and Slavoj Žižek, Breckman uniquely situates these important theorists within two hundred years of European thought and extends their profound relevance to today's political activism.

In his arguments that science itself can answer moral questions, Sam Harris often appeals to our intuitions about the badness of suffering. If we share these intuitions, Harris argues, we’ve taken a significant step in conceding to a basically utilitarian worldview. In this chapter, I critically assess Harris’ arguments and find them deeply wanting.

Writings by a thinker—a psychiatrist, a philosopher, a cybernetician, and a poet—whose ideas about mind and brain were far ahead of his time. Warren S. McCulloch was an original thinker, in many respects far ahead of his time. McCulloch, who was a psychiatrist, a philosopher, a teacher, a mathematician, and a poet, termed his work “experimental epistemology.” He said, “There is one answer, only one, toward which I've groped for thirty years: to find out how brains work.” Embodiments of (...) Mind, first published more than fifty years ago, teems with intriguing concepts about the mind/brain that are highly relevant to recent developments in neuroscience and neural networks. It includes two classic papers coauthored with Walter Pitts, one of which applies Boolean algebra to neurons considered as gates, and the other of which shows the kind of nervous circuitry that could be used in perceiving universals. These first models are part of the basis of artificial intelligence. Chapters range from “What Is a Number, that a Man May Know It, and a Man, that He May Know a Number,” and “Why the Mind Is in the Head,” to “What the Frog's Eye Tells the Frog's Brain” (with Jerome Lettvin, Humberto Maturana, and Walter Pitts), “Machines that Think and Want,” and “A Logical Calculus of the Ideas Immanent in Nervous Activity” (with Walter Pitts). Embodiments of Mind concludes with a selection of McCulloch's poems and sonnets. This reissued edition offers a new foreword and a biographical essay by McCulloch's one-time research assistant, the neuroscientist and computer scientist Michael Arbib. (shrink)

Warren Quinn was widely regarded as a moral philosopher of remarkable talent. This collection of his most important contributions to moral philosophy and the philosophy of action has been edited for publication by Philippa Foot. Quinn laid out the foundations for an anti-utilitarian moral philosophy that was critical of much contemporary work in ethics, such as the anti-realism of Gilbert Harman and the neo-subjectivism of Bernard Williams. Quinn's own distinctive moral theory is developed in the discussion of substantial, practical (...) moral issues. For example, there are important pieces here on the permissibility of abortion, the justification of punishing criminals when no particular good seems likely to result, and on the distinction between killing and allowing to die, a distinction crucial to the subject of euthanasia and other topics in medical ethics. The volume would be ideally suited to upper-level undergraduate courses and graduate seminars on the foundations of ethics. (shrink)

This paper distinguishes four senses of naturalism: reductive physicalism; a naturalism that departs from what Thompson calls “natural-historical judgments”; a naturalism that recognizes that physical nature is located within the space of reasons; and a phenomenological naturalism that shifts the focus to the “natural” experiences of subjects who encounter the world. The paper argues for a “phenomenological neo-Aristotelianism” that accounts both for the internal justification of our first-order moral experience and the need for a broader grounding in a universalistic account (...) of the goods of agency.

"Ashby includes the great thinkers and periods that have shaped Western ethics: the Greeks, the Hebrew prophets, the Roman Stoics, St. Augustine, the medieval ethicists, the Renaissance and Reformation, the Enlightenment, the Romantics, and the radical revolutions of the late nineteenth and early twentieth centuries. In the period from 1850 to 1920, Ashby notes, the transformations wrought by the four great modern thinkers - Darwim, Marx, Nietzsche, and Freud - both extended and significantly challenged the traditional core beliefs of the (...) West and, as a result, bestowed upon us a profound moral crisis, one that we have not yet successfully met. Consequently, as we stand at the brink of the twenty-first century, with its further technological breakthroughs and social upheavals, how will we deal with the moral uncertainties that await us? In his final chapter Ashby contends that while remaining alive to our Western ethical heritage, we will have no choice but to confront its basic presuppositions as we move into a more pluralistic society, for he asserts that the ideology of the future cannot be exclusively Western; future history cannot be purely Western history. So, while this history of ethics cannot tell us how to live, it can offer to the reader what is prerequisite to a more satisfying life: an insightful and inclusive history of where our own ethical beliefs have come from and a sense of the challenges that await us all.".

Posner & Raichle'sImages of mindis an excellent educational book and very well written. Some flaws as a scientific publication are: (a) the accuracy of the linear subtraction method used in PET is subject to scrutiny by further research at finer spatial-temporal resolutions; (b) lack of accuracy of the experimental paradigm used for EEG complementary studies.

The work in progress reported by Wright & Liley shows great promise, primarily because of their experimental and simulation paradigms. However, their tentative conclusion that macroscopic neocortex may be considered (approximately) a linear near-equilibrium system is premature and does not correspond to tentative conclusions drawn from other studies of neocortex.

This commentary focuses on how bottom-up neocortical models can be developed into eigenfunction expansions of probability distributions appropriate to describe short-term memory in the context of scalp EEG. The mathematics of eigenfunctions are similar to the top-down eigenfunctions developed by Nunez, despite different physical manifestations. The bottom-up eigenfunctions are at the local mesocolumnar scale, whereas the top-down eigenfunctions are at the global regional scale. Our respective approaches have regions of substantial overlap, and future studies may expand top-down eigenfunctions into the (...) bottom-up eigenfunctions, yielding a model of scalp EEG expressed in terms of columnar states of neocortical processing of attention and short-term memory.

This essay presents a scenario of the origin of life that is based on analysis of biological architecture and mechanical design at the microstructural level. My thesis is that the same architectural and energetic constraints that shape cells today also guided the evolution of the first cells and that the molecular scaffolds that support solid-phase biochemistry in modern cells represent living microfossils of past life forms. This concept emerged from the discovery that cells mechanically stabilize themselves using tensegrity architecture and (...) that these same building rules guide hierarchical self-assembly at all size scales (Sci Amer 278:48–57;1998). When combined with other fundamental design principles (e.g., energy minimization, topological constraints, structural hierarchies, autocatalytic sets, solid-state biochemistry), tensegrity provides a physical basis to explain how atomic and molecular elements progressively self-assembled to create hierarchical structures with increasingly complex functions, including living cells that can self-reproduce.

This book evaluates the consequences of economic, social, environmental and cultural change on people living and working within Teesside in the North-East of England. It assesses the lived experiences, working lives, health and cultural perspectives of residents and key stakeholders in the wake of serious de-industralisation in the region. The narrative is embedded within the long-term industrial history of Stockton: an area once dominated by steel, coal and chemical industries. This past still continues to shape its future and influences the (...) ways in which that future is conceived and envisioned. The author explores a 'biography of place' analytical framework to offer a holistic view of the area, which considers the interaction between the social, economic, cultural, visual and environmental legacy of the community, which is firmly grounded in the past, present and future prospects of those who live and work there.

The role of paleontology in evolutionary biology between the publication of The Origin of Species in 1859 and the Evolutionary Synthesis of the 1940s is frequently described as mostly misguided failure. However, a significant number of American and British PDPS invertebrate paleontologists of this period did devote considerable attention to evolution, and their evolutionary theories and conclusions were a good deal more diverse and nuanced than previous histories have suggested. This paper brings into focus a number of important but underrecognized (...) aspects of the history of paleontology within the history of biology, including that PDPS paleontologists were not all as theoretically backward as they have been portrayed; that the post-Synthesis narrative of the history of evolution should be continually reevaluated, in part to decouple historical understanding from the agendas of authors who have used history to advance particular views of evolution; and that there is a much richer story to be told about the history of evolutionary biology in both the pre- and post-Synthesis eras.

Critically engages the work of American philosopher Richard J. Bernstein.

An article by Warren Reich in the December 1994 issue of this journal concludes that the word "bioethics" and the field of study it names experienced a "bilocated birth" in 1970/1971 under Van Rensselaer Potter, at the University of Wisconsin, and André Hellegers, at Georgetown University. Further historical inquiry confirms (1) that there were, from the start, some major differences—even clashes—between the Potter and the Hellegers/Georgetown understandings of bioethics; and (2) that the Hellegers/Georgetown approach came to be the more (...) widely accepted meaning of the term, while Potter's idea of bioethics remained largely marginalized. However, this inquiry also results in a third, unanticipated, conclusion: that Hellegers (in contrast to the dominant model offered by the Georgetown scholars) actually proposed a global approach to bioethics, bringing his vision much closer to Potter's evolving view than previously has been acknowledged.

Extensive historical sleuthing reveals that the word "bioethics" and the field of study it names experienced, in 1970/1971, a "bilocated birth" in Madison, Wisconsin, and in Washington, D.C. Van Rensselaer Potter, at the University of Wisconsin first coined the term; and André Hellegers, at Georgetown University, at the very least, latched onto the already-existing word "bioethics" and first used it in an institutional way to designate the focused area of inquiry that became an academic field of learning and a movement (...) regarding public policy and the life sciences. A further comparison of the Potter and the Hellegers/Georgetown understandings of bioethics and the relative acceptance of the two views will appear in the March 1995 issue of this journal. (shrink)

This is the first major study of Marx and the Young Hegelians in twenty years. The book offers a new interpretation of Marx's early development, the political dimension of Young Hegelianism, and that movement's relationship to political and intellectual currents in early nineteenth-century Germany. Warren Breckman challenges the orthodox distinction drawn between the exclusively religious concerns of Hegelians in the 1830s and the sociopolitical preoccupations of the 1840s. He shows that there are inextricable connections between the theological, political and (...) social discourses of the Hegelians in the 1830s. The book draws together an account of major figures such as Feuerbach and Marx, with discussions of lesser-known but significant figures such as Eduard Gans, August Cieszkowski, Moses Hess, F. W. J. Schelling as well as such movements as French Saint-Simonianism and 'positive philosophy'. Wide-ranging in scope and synthetic in approach, this is an important book for historians of philosophy, theology, political theory and nineteenth-century ideas. (shrink)
