Perhaps no technological innovation has so dominated the second half of the twentieth century as has the introduction of the programmable computer. It is quite difficult if not impossible to imagine how contemporary affairs—in business and science, communications and transportation, governmental and military activities, for example—could be conducted without the use of computing machines, whose principal contribution has been to relieve us of the necessity for certain kinds of mental exertion. The computer revolution has reduced our mental labors by means (...) of these machines, just as the Industrial Revolution reduced our physical labor by means of other machines. (shrink)

Historian James H. Jones published the first edition of Bad Blood, the definitive history of the Tuskegee Syphilis Experiment, in 1981. Its clear-eyed examination of that research and its implications remains a bioethics classic, and the 30-year anniversary of its publication served as the impetus for the reexamination of research ethics that this symposium presents. Recent revelations about the United States Public Health Service study that infected mental patients and prisoners in Guatemala with syphilis in the late 1940s in (...) order to determine the efficacy of treatment represent only one of the many attestations to the persistence of ongoing, critical, and underaddressed issues in research ethics that Bad Blood first explored. Those issues include, but are not limited to: the complex and contested matters of the value of a given research question, the validity of the clinical trial designed to address it, and the priorities of science.

The development of science has been a distinctive feature of human history in recent times, especially in the seventeenth and eighteenth centuries. In light of the problems that define the philosophy of science today, James Fetzer provides a foundation for inquiry into the nature of science, the history of science, and the relationship between the two. In Philosophy of Science, Fetzer investigates the aim and methods of empirical science and examines the importance of methodological commitments to the study of (...) science and the significance of interpretations of probability for understanding laws of nature and scientific explanations. This book offers a welcome framework for investigating the most recent work and the most promising solutions to the central problems that arise within this discipline. The result is a timely introduction to an increasingly important field. -- Publisher description. (shrink)

This sequel to the widely read Zen and the Brain continues James Austin's explorations into the key interrelationships between Zen Buddhism and brain research. In Zen-Brain Reflections, Austin, a clinical neurologist, researcher, and Zen practitioner, examines the evolving psychological processes and brain changes associated with the path of long-range meditative training. Austin draws not only on the latest neuroscience research and new neuroimaging studies but also on Zen literature and his personal experience with alternate states of consciousness.Zen-Brain Reflections takes (...) up where the earlier book left off. It addresses such questions as: how do placebos and acupuncture change the brain? Can neuroimaging studies localize the sites where our notions of self arise? How can the latest brain imaging methods monitor meditators more effectively? How do long years of meditative training plus brief enlightened states produce pivotal transformations in the physiology of the brain? In many chapters testable hypotheses suggest ways to correlate normal brain functions and meditative training with the phenomena of extraordinary states of consciousness.After briefly introducing the topic of Zen and describing recent research into meditation, Austin reviews the latest studies on the amygdala, frontotemporal interactions, and paralimbic extensions of the limbic system. He then explores different states of consciousness, both the early superficial absorptions and the later, major "peak experiences." This discussion begins with the states called kensho and satori and includes a fresh analysis of their several different expressions of "oneness." He points beyond the still more advanced states toward that rare ongoing stage of enlightenment that is manifest as "sage wisdom."Finally, with reference to a delayed "moonlight" phase of kensho, Austin envisions novel links between migraines and metaphors, moonlight and mysticism. The Zen perspective on the self and consciousness is an ancient one. Readers will discover how relevant Zen is to the neurosciences, and how each field can illuminate the other. (shrink)

A personal story of the ways in which persistence, chance, and creativity interact in biomedical research. This first book by the author of Zen and the Brain examines the role of chance in the creative process. James Austin tells a personal story of the ways in which persistence, chance, and creativity interact in biomedical research; the conclusions he reaches shed light on the creative process in any field. Austin shows how, in his own investigations, unpredictable events shaped the outcome (...) of his research and brought about novel results. He then goes beyond this story of serendipity to propose a new classification of the varieties of chance, drawing on his own research and examples from the history of science—including the famous accidents that led Fleming to the discovery of penicillin. Finally, he explores the nature of the creative process, considering not only the environmental and neurophysiological correlates of creativity but also the role of intuition in both scientific discoveries and spiritual quests. This updated MIT Press paperback edition includes a new introduction and recent material on medical research, creativity, and spirituality. (shrink)

Taking Brian Cantwell Smith’s study, “Limits of Correctness in Computers,” as its point of departure, this article explores the role of models in computer science. Smith identifies two kinds of models that play an important role, where specifications are models of problems and programs are models of possible solutions. Both presuppose the existence of conceptualizations as ways of conceiving the world “in certain delimited ways.” But high-level programming languages also function as models of virtual (or abstract) machines, while low-level programming (...) languages function as models of causal (or physical) machines. The resulting account suggests that sets of models embedded within models are indispensable for computer programming. (shrink)

The purpose of this paper is to explore three alternative frameworks for understanding the nature of language and mentality, which accent syntactical, semantical, and pragmatical aspects of the phenomena with which they are concerned, respectively. Although the computational conception currently exerts considerable appeal, its defensibility appears to hinge upon an extremely implausible theory of the relation of form to content. Similarly, while the representational approach has much to recommend it, its range is essentially restricted to those units of language that (...) can be understood in terms of undefined units. Thus, the only alternative among these three that can account for the meaning of primitive units of language is one emphasizing the basic role of skills, habits, and tendencies in relating signs and dispositions.

On some accounts, early reflection on the nature of human cognition focused on its physical or physiological causes (as, for example, when in fragment 105 Empedocles identifies thought with blood). On other accounts, there was an identifiable process of semantic development in which a number of perception-oriented terms for knowing (e.g. gignôskô, oida, noeô, and suniêmi) took on a more intellectual orientation. Although some find evidence of this transition in the poems of Solon and Archilochus, appreciation for a distinction between (...) sensing and knowing is more plausibly credited to the Presocratic thinkers Heraclitus and Parmenides. It is unclear whether Heraclitus regarded sense perception as an essential first stage in acquiring knowledge (or an inherently inferior form of awareness), but the goddess in Parmenides’ poem unambiguously urges the youth to whom she speaks to set aside the testimony of eye and ear and instead ‘judge by reason’ the nature of what-is.

Offers a vital, unique and agenda-setting perspective for the field of social epistemology – the philosophical basis for prescribing the social means and ends for pursuing knowledge.

The standard interpretation of the imitation game is defended over the rival gender interpretation though it is noted that Turing himself proposed several variations of his imitation game. The Turing test is then justified as an inductive test not as an operational definition as commonly suggested. Turing's famous prediction about his test being passed at the 70% level is disconfirmed by the results of the Loebner 2000 contest and the absence of any serious Turing test competitors from AI on the (...) horizon. But, reports of the death of the Turing test and AI are premature. AI continues to flourish and the test continues to play an important philosophical role in AI. Intelligence attribution, methodological, and visionary arguments are given in defense of a continuing role for the Turing test. With regard to Turing's predictions one is disconfirmed, one is confirmed, but another is still outstanding. (shrink)

We applaud the spirit of MacNeilage's attempts to better explain the evolution and cortical control of speech by drawing on the vast literature in nonhuman primate neurobiology. However, he oversimplifies motor cortical fields and their known individual functions to such an extent that he undermines the value of his effort. In particular, MacNeilage has lumped together the functional characteristics across multiple mesial and lateral motor cortex fields, inadvertantly creating two hypothetical centers that simply may not exist.

Based on the Zen philosophy about focusing away from the self, a guide to "neural Zen" meditative practices draws on recent findings in brain research to outline recommendations for various methods of pursuing a balanced, selfless state of ...

[opening paragraph]: On page 2 of this volume our co-editors set admirable goals. They seek ‘method- ologies that can provide an open link to objective, empirically based description'. Moreover, they want ‘explicit examples of practical knowledge, in case studies'. My comments will address these words and goals. I too prefer the case-method approach, and seek practical ways to access states of consciousness. Then, at the top of page 4, Professors Varela and Shear define ‘nonconscious phenomena’ as those the subject is (...) not aware of. In order to comment further on this issue of awareness and non-awareness, I'll first need to pick up on their other key word -- ‘blindness’ -- as introduced in their section VII. I'll then redirect it. For surely a central topic to confront is our own self-imposed blindfold. Which subterranean region of consciousness are we most unaware of? What thwarts our efforts to study all of its regions? Our own covert self. (shrink)

If the decades of the forties through the sixties were dominated by discussion of Hempel's “covering law“ explication of explanation, that of the seventies was preoccupied with Salmon's “statistical relevance” conception, which emerged as the principal alternative to Hempel's enormously influential account. Readers of Wesley C. Salmon's Scientific Explanation and the Causal Structure of the World, therefore, ought to find it refreshing to discover that its author has not remained content with a facile defense of his previous investigations; on the (...) contrary, Salmon offers an original account of different kinds of explications, advances additional criticisms of various alternative theories, and elaborates a novel “two-tiered“ analysis of explanation that tacitly depends upon a “two-tiered” account of homogeneity. Indeed, if the considerations that follow are correct, Salmon has not merely refined his statistical relevance account but has actually abandoned it in favor of a “causal/mechanistic“ construction. This striking development suggests that the theory of explanation is likely to remain as lively an arena of debate in the eighties as it has been in the past. (shrink)

The book uses Zen Buddhism as the opening wedge for an extraordinarily wide-ranging exploration of consciousness.

Public relations (PR) is trying to gain professional status by stressing specialized education for the field. Results are mixed, at best. Most practitioners have had educations in some aspects of communication, but so far only a small (though growing) number acknowledge it as being in public relations per se. Furthermore, when certain key attributes of professionalism are measured, practitioners with formal educations in public relations differ little from those without such educations.

We need to clarify at least four aspects of selfhood if we are to reach a better understanding of consciousness in general, and of its alternate states. First, how did we develop our self-centred psychophysiology? Second, can the four familiar lobes of the brain alone serve, if only as preliminary landmarks of convenience, to help understand the functions of our many self-referent networks? Third, what could cause one's former sense of self to vanish from the mental field during an extraordinary (...) state of consciousness? Fourth, when a person's physical and psychic self do drop off briefly, how has conscious experience then been transformed? In particular, what happens to that subject's personal sense of time? Our many-sided self arose in widely distributed brain networks. Since infancy, these self-oriented circuits have been over-conditioned by limbic biases. Selfhood then seems to have evolved along lines suggesting at least in shorthand the operations of a kind of ‘I-Me-Mine’ complex. But what happens when this egocentric triad briefly dissolves? Novel states of consciousness emerge. Two personally-observed states are discussed: insight-wisdom ; internal absorption. How do these two states differ phenomenologically? The physiological processes briefly suggested here emphasize shifts in deeper systems, and pivotal roles for thalamo-cortical interactions in the front and back of the brain. (shrink)

In an evocative and provocative way Harriet Beecher Stowe focused the attention of her reader on the "sympathies of Christ/' to show that where these sympathies were manifested among whites and blacks, God was present, manifesting his power, liberating all in bondage.
