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)

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.

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)

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.

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)

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.

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 ...

Some reasons are thought to depend on relations between people, such as that of a promiser to a promisee. It has sometimes been assumed that all reasons that are relational in this way are moral obligations. I argue, via a counter example, that there are non-obligatory relational reasons. If true, this has ramifications for relational theories of morality.

[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)

A lineage of prominent philosophers who have discussed the second-person relation can be regarded as advancing structural accounts. They posit that the second-person relation effects one transformative change to the structure of practical reasoning. In this paper, I criticise this orthodoxy and offer an alternative, substantive account. That is, I argue that entering into second-personal relations with others does indeed affect one's practical reasoning, but it does this not by altering the structure of one's agential thought, but by changing what (...) reasons can become available. The importance of second-personal thought for action is heterogenous. Second-person relations make possible the emergence of a wide variety of different kinds of practical reasons: creating some, revealing others. Recognising this diminishes the appeal of the traditional, structural accounts of the practical significance of such second-personal relations. Moving away from structural accounts facilitates a more thorough understanding of the intersubjective form of action. (shrink)

The idea that human thought requires the execution of mental algorithms provides a foundation for research programs in cognitive science, which are largely based upon the computational conception of language and mentality. Consideration is given to recent work by Penrose, Searle, and Cleland, who supply various grounds for disputing computationalism. These grounds in turn qualify as reasons for preferring a non-computational, semiotic approach, which can account for them as predictable manifestations of a more adquate conception. Thinking does not ordinarily require (...) the execution of mental algorithms, which appears to be at best no more than one rather special kind of thinking. (shrink)

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)

The purpose of this paper is to provide a systematic defense of the single-case propensity account of probabilistic explanation from the criticisms advanced by Hanna and by Humphreys and to offer a critical appraisal of the aleatory conception advanced by Humphreys and of the deductive-nomological-probabilistic approach Railton has proposed. The principal conclusion supported by this analysis is that the Requirements of Maximal Specificity and of Strict Maximal Specificity afford the foundation for completely objective explanations of probabilistic explananda, so long as (...) they are employed on the basis of propensity criteria of explanatory relevance.

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.
