If connectionist computational models explain the acquisition of complex cognitive skills, errors in such models would also help explain unusual brain activity such as in creativity – as well as in mental illness, including childhood onset problems with social behaviors in autism, the inability to maintain focus in attention deficit and hyperactivity disorder (ADHD), and the lack of motivation of depression disorders.

In a recent study of a patient in a persistent vegetative state, [Owen, A. M., Coleman, M. R., Boly, M., Davis, M. H., Laureys, S., & Pickard, J. D. . Detecting awareness in the vegetative state. Science, 313, 1402] claimed that they had demonstrated the presence of consciousness in this patient. This bold conclusion was based on the isomorphy between brain activity in this patient and a set of conscious control subjects, obtained in various imagery tasks. However, establishing consciousness (...) in unresponsive patients is fraught with methodological and conceptual difficulties. The aim of this paper is to demonstrate that the current debate surrounding consciousness in VS patients has parallels in the artificial intelligence debate as to whether machines can think. Basically, used a method analogous to the Turing test to reveal the presence of consciousness, whereas their adversaries adopted a line of reasoning akin to Searle’s Chinese room argument. Highlighting the correspondence between these two debates can help to clarify the issues surrounding consciousness in non-communicative agents. (shrink)

An infinite lottery machine is used as a foil for testing the reach of inductive inference, since inferences concerning it require novel extensions of probability. Its use is defensible if there is some sense in which the lottery is physically possible, even if exotic physics is needed. I argue that exotic physics is needed and describe several proposals that fail and at least one that succeeds well enough.

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle asserts that (...) "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

In lieu of an abstract, here is a brief excerpt of the content:THE SUBSTANTIAL UNITY OF MATERIAL SUBSTANCES ACCORDING TO JOHN POINSOT JOHN D. KRONEN The University of St. Thomas St. Paul, Minnesota EVERY SUBSTANCE metaphysician must answer several difficult questions peculiar to his or her ontology. In this paper I will examine John Poinsot's answer to two of these questions, one concerning the nature of the form of substantial composites, and one concerning which material objects are (...) substantial composites. I shall argue that Poinsot's answers to these questions show the untenability of a structuralist view of substantial form and of a reductive materialist view of living beings. But before considering these questions I must briefly outline Poinsot's view of what the general nature of substance is, as explained in his treatise on material logic.1 Poinsot's Account of Substance in General In the section of his Material Logic concerned with the categories Poinsot gives a succinct account of the nature of substance 1 Cursus Philosophicus thomisticus; vol. I, Ars logicae prima et secunda pars, ed. P. Beato Reiser (Turin, Italy: Marietti, 1820), Q. XV, pp. 523-527. It should be noted that I am not concerned in this paper with describing either the psychological origin of the notion of substance, or of justifying it against phenomenalism. My only aim is to show how such a view of substance leads to a certain notion of form when it is applied, so to speak, to material objects. For an interesting account of the origin of the concept of substance in Poinsot see John Deely, Tractatus De Signis: The Semiotic of John Poinsot (Los Angeles, Berkeley, and London: The University of California Press, 1985), p. 86, n. 16. Deely takes it that Poinsot has a deeper categorial scheme than that of Aristotle from which the latter's scheme "emerges," as it were. In this article, then, I am not concerned with that deeper scheme which Deely refers to in this interesting note. 599 600 JOHN D. KRONEN in general and of its relation to the supposit and to the act of existing. He notes that by " substance " narrowly considered is meant that kind of essence to "which it is due to exist in itself as opposed to that kind to which it is due to exist in another" (i.e., an accident).2 He defends this as the primary " definition " 3 of substance against the other definition of it which is " that which stands under accidents," on the grounds that a thing must exist in itself, at least ontologically speaking, before it can support accidents 4 and that to define substance as that which supports accidents is to define it in relation to other things, not itself. This point is important because many modern and contemporary philosophers who have attacked the notion of substance have done so by arguing that there are no beings which stand under accidents. For Poinsot this attack, even if successful, would show that there are no accidents, not that there are no substances. Poinsot insists that " substance " connotes a quiddity to which to exist in itself is due since actual existence does not belong to the essence of any created thing.5 Further, Poinsot insists that to exist in itself " connotes more than a mere negation of existing in another; rather it connotes a positive perfection." This is because to exist in a dependent way is to exist in an imperfect way, so to exist independently must be to exist in a more perfect way.6 Finally, Poinsot distinguishes between the substance and the supposit. The substance is the complete nature of the thing, while 2 Ibid., p. 523. a " Substance " as a supreme genus cannot strictly be defined since it cannot be differentiated from any higher genus. 4 Haec autem proprietas existendi per se intelligitur vel secundum considerationem absolutam et in ordine ad se, et sic dicitur subsistens, quasi non indignes alio ut sustentetur, sed in se sistens; vel dicitur secundum habitudinem ad alia, quatenus ilia sustentat in esse, et sic dicitur non solum subsistens, sed etiam substans. Ibid., p. 523. 5 ••• esse actu per se vel in alio non est ipsa quidditas substantiae vel accidentis, quia esse seu existere in nulla quidditate creata... (shrink)

The inaugural title in the new, Open Access series BSPS Open, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference. The fundamental burden of a theory of inductive inference is to determine which are the good inductive inferences or relations of inductive support and why it is that they are so. The traditional approach is modeled on that taken in accounts of deductive inference. It seeks universally applicable schemas or rules or a single (...) formal device, such as the probability calculus. After millennia of halting efforts, none of these approaches has been unequivocally successful and debates between approaches persist. The Material Theory of Induction identifies the source of these enduring problems in the assumption taken at the outset: that inductive inference can be accommodated by a single formal account with universal applicability. Instead, it argues that that there is no single, universally applicable formal account. Rather, each domain has an inductive logic native to it. Which that is, and its extent, is determined by the facts prevailing in that domain. Paying close attention to how inductive inference is conducted in science and copiously illustrated with real-world examples, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference.

Contemporary philosophical discussion of religion neglects dualistic religions: although Manichaeism from time to time is accorded mention, Zoroastrianism, a more plausible form of religious dualism, is almost entirely ignored. We seek to change this state of affairs. To this end we present the basic tenets of Zoroastrian dualism, argue that objections to the Zoroastrian conception of God are less strong than typically imagined, argue that objections to the Zoroastrian conception of the devil are less strong than typically imagined, and offer (...) some brief concluding thoughts.

Applying an ever more radical hermeneutics, John D. Caputo breaks down the name of God in this irrepressible book. Instead of looking at God as merely a name, Caputo views it as an event, or what the name conjures or promises in the future. For Caputo, the event exposes God as weak, unstable, and barely functional. While this view of God flies in the face of most religions and philosophies, it also puts up a serious challenge to fundamental tenets (...) of theology and ontology. Along the way, Caputo’s readings of the New Testament, especially of Paul’s view of the Kingdom of God, help to support the "weak force" theory. This penetrating work cuts to the core of issues and questions—What is the nature of God? What is the nature of being? What is the relationship between God and being? What is the meaning of forgiveness, faith, piety, or transcendence?—that define the terrain of contemporary philosophy of religion. (shrink)

Part I. Gnosticism and other religious movements of antiquity -- part II. Crossing boundaries : Gnosticism and Platonism.

Preface: This volume originated in a conference on "The Place of Thought Experiments in Science and Philosophy" which was organized by us and held at the Center for Philosophy of Science at the University of Pittsburgh, April 18-20, 1986. The idea behind this conference was to encourage philosophers and scientists to talk to each other about the role of thought experiments in their various disciplines. These papers were either written for the conference, or were written after it by commentators and (...) other participants.... We hope that this volume will be of use to other philosophers and scientists who are interested in thought experiments, as well as inspire more work in this area.... (shrink)

In books such as The World Within the World and The Anthropic Cosmological Principle, astronomer John Barrow has emerged as a leading writer on our efforts to understand the universe. Timothy Ferris, writing in The Times Literary Supplement of London, described him as "a temperate and accomplished humanist, scientist, and philosopher of science--a man out to make a contribution, not a show." Now Barrow offers the general reader another fascinating look at modern physics, as he explores the quest for (...) a single, unifying theory that will unlock nature's secrets. Theories of Everything is more than a history of science, more than a popular report on recent research and discoveries. Barrow provides a reflective, intelligent commentary on what a true Theory of Everything would be--its ingredients, its limitations, and what it could tell us about the universe. Never before, he writes, have physicists been so confident and so eager in the hunt for this "cosmic Rosetta Stone," as he calls it: "a single all-embracing picture of all the laws of nature from which the inevitability of all things seen must follow with unimpeachable logic." He lays out eight essential ingredients for a Theory of Everything and then explores each in turn, tracing how our knowledge has developed and how scientific discovery relates to our changing philosophy and religious thought in each area. Some of these ingredients are obvious--the laws of nature must be explained, for example, as well as its organizing principles--but others may be surprising, such as broken symmetries and selection biases. A Theory of Everything must account for the fact that the universe is "messy and complicated," he tells us, and for the limitations imposed by the questions we ask and the information we can obtain. The key lies in the remarkable capacity of mathematics to express the fundamental workings of the physical world--a language that the human mind is uniquely equipped to understand and manipulate. Barrow examines what mathematics actually is and describes how it makes the universe intelligible and provides a path to the underlying coherence in nature--which has led, in fact, to arguments that the universe itself is a vast computer. Yet even the most complete theory, even the most comprehensive mathematical explanation, cannot account for the uncomputable varieties of human experience and thought. "No non-poetic account of reality," he writes, "can be complete." In a field where the authorities converse in equations and mathematical notations, John Barrow speaks with the voice of thoughtful and knowledgeable humanist. Written with eloquence and expertise, Theories of Everything establishes a new perspective on humanity's efforts to explain the universe. (shrink)

Loneliness in medicine is a serious problem not just for patients, for whom illness is intrinsically isolating, but also for physicians in the contemporary condition of medicine. We explore this problem by investigating the ideal physician-patient relationship, whose analogy with friendship has held enduring normative appeal. Drawing from Talbot Brewer and Nir Ben-Moshe, we argue that this appeal lies in a dynamic form of companionship incompatible with static models of friendship-like physician-patient relationships: a mutual refinement of embodied virtue that draws (...) both persons together. The ideal physician-patient relationship has a dialectical character that fosters each member's improvement of phenomenologically recognizing and embodying moral virtues. A key component of this dynamic is a commitment to the common goal of the patient's health, realized through joint interactivities and conversations over time. The physician's presence to the patient's suffering—understood best as an alienating phenomenological condition for the patient—orients and discloses possibilities for virtuous caregiving by structuring the meanings of the goals, conversations, and joint narrative constitutive of their relationship. Presence to suffering, paradoxically, is perhaps an important prerequisite for this dynamic partnership. These activities dialectically build an interpretive horizon of understanding through which moral goods and character refinement—in and for the other—may become revealed for both persons in their shared being-in-the-world. This analysis of suffering, mood, and revealing of (possible) moral goods has implications for addressing the modern problem of loneliness for patients and physicians, who are increasingly inhibited from building flourishing relationships with each other.

John D. Caputo explores the very roots of religious thinking in this thought-provoking book. Compelling questions come up along the way: 'What do I love when I love my God?' and 'What can Star Wars tell us about the contemporary use of religion?' Why is religion for many a source of moral guidance in a postmodern, nihilistic age? Is it possible to have 'religion without religion'? Drawing on contemporary images of religion, such as Robert Duvall's film _The Apostle_, Caputo (...) also provides some fascinating and imaginative insights into religious fundamentalism. (shrink)

I deny that the world is fundamentally causal, deriving the skepticism on non-Humean grounds from our enduring failures to find a contingent, universal principle of causality that holds true of our science. I explain the prevalence and fertility of causal notions in science by arguing that a causal character for many sciences can be recovered, when they are restricted to appropriately hospitable domains. There they conform to a loose collection of causal notions that form a folk science of causation. This (...) recovery of causation exploits the same generative power of reduction relations that allows us to recover gravity as a force from Einstein's general relativity and heat as a conserved fluid, the caloric, from modern thermal physics, when each theory is restricted to appropriate domains. Causes are real in science to the same degree as caloric and gravitational forces. (shrink)

In a material theory of induction, inductive inferences are warranted by facts that prevail locally. This approach, it is urged, is preferable to formal theories of induction in which the good inductive inferences are delineated as those conforming to some universal schema. An inductive inference problem concerning indeterministic, non-probabilistic systems in physics is posed and it is argued that Bayesians cannot responsibly analyze it, thereby demonstrating that the probability calculus is not the universal logic of induction.

Thought experiments in science are merely picturesque argumentation. I support this view in various ways, including the claim that it follows from the fact that thought experiments can err but can still be used reliably. The view is defended against alternatives proposed by my cosymposiasts.

In these spirited essays, John D. Caputo continues the project he launched with Radical Hermeneutics of making hermeneutics and deconstruction work together.

Bayesian probabilistic explication of inductive inference conflates neutrality of supporting evidence for some hypothesis H (“not supporting H”) with disfavoring evidence (“supporting not-H”). This expressive inadequacy leads to spurious results that are artifacts of a poor choice of inductive logic. I illustrate how such artifacts have arisen in simple inductive inferences in cosmology. In the inductive disjunctive fallacy, neutral support for many possibilities is spuriously converted into strong support for their disjunction. The Bayesian “doomsday argument” is shown to rely entirely (...) on a similar artifact, for the result disappears in a reanalysis that employs fragments of inductive logic able to represent evidential neutrality. Finally, the mere supposition of a multiverse is not yet enough to warrant the introduction of probabilities without some factual analog of a randomizer over the multiverses. (shrink)

The Insistence of God presents the provocative idea that God does not exist, God insists, while God’s existence is a human responsibility, which may or may not happen. For John D. Caputo, God’s existence is haunted by "perhaps," which does not signify indecisiveness but an openness to risk, to the unforeseeable. Perhaps constitutes a theology of what is to come and what we cannot see coming. Responding to current critics of continental philosophy, Caputo explores the materiality of perhaps and (...) the promise of the world. He shows how perhaps can become a new theology of the gaps God opens. (shrink)

John Barrow is increasingly recognized as one of our most elegant and accomplished science writers, a brilliant commentator on cosmology, mathematics, and modern physics. Barrow now tackles the heady topic of impossibility, in perhaps his strongest book yet. Writing with grace and insight, Barrow argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. He first examines the limits on scientific inquiry imposed by the deficiencies of the human mind: (...) our brain evolved to meet the demands of our immediate environment, Barrow notes, and much that lies outside this small circle may also lie outside our understanding. Barrow investigates practical impossibilities, such as those imposed by complexity, uncomputability, or the finiteness of time, space, and resources. Is the universe finite or infinite? Can information be transmitted faster than the speed of light? The book also examines the deeper theoretical restrictions on our ability to know, including Godel's theorem--which proved that there were things that could not be proved--and Arrow's Impossibility theorem about democratic voting systems. Finally, having explored the limits imposed on us from without, Barrow considers whether there are limits we should impose upon ourselves. For instance, if the secrets of the atom are to be found only by recreating extreme environments at great financial cost, just how much should we devote to that quest? Weaving together this intriguing tapestry, he illuminates some of the most profound questions of science, from the possibility of time travel to the very structure of the universe. (shrink)

Landauer's Principle asserts that there is an unavoidable cost in thermodynamic entropy creation when data is erased. It is usually derived from incorrect assumptions, most notably, that erasure must compress the phase space of a memory device or that thermodynamic entropy arises from the probabilistic uncertainty of random data. Recent work seeks to prove Landauer’s Principle without using these assumptions. I show that the processes assumed in the proof, and in the thermodynamics of computation more generally, can be combined to (...) produce devices that both violate the second law and erase data without entropy cost, indicating an inconsistency in the theoretical system. Worse, the standard repertoire of processes selectively neglects thermal fluctuations. Concrete proposals for how we might measure dissipationlessly and expand single molecule gases reversibly are shown to be fatally disrupted by fluctuations. Reversible, isothermal processes on molecular scales are shown to be disrupted by fluctuations that can only be overcome by introducing entropy creating, dissipative processes. (shrink)

I am grateful to Peter Achinstein, Don Howard, and the other participants at the conference, 'The Role of Experiments in Scientific Changer', Virginia Polytechnic Institute and State University, 30 March to 1 April, 1990, for helpful discussion, and especially to Ron Laymon for his discussion comments presented at the conference on an earlier version of this paper.

Standard descriptions of thermodynamically reversible processes attribute contradictory properties to them: they are in equilibrium yet still change their state. Or they are comprised of non-equilibrium states that are so close to equilibrium that the difference does not matter. One cannot have states that both change and no not change at the same time. In place of this internally contradictory characterization, the term “thermodynamically reversible process” is here construed as a label for a set of real processes of change involving (...) only non-equilibrium states. The properties usually attributed to a thermodynamically reversible process are recovered as the limiting properties of this set. No single process, that is, no system undergoing change, equilibrium or otherwise, carries those limiting properties. The paper concludes with an historical survey of characterizations of thermodynamically reversible processes and a critical analysis of their shortcomings. (shrink)
