How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours (...) to be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define "the predictive brain." What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

The second edition of a unique introductory text, offering an account of the logical tradition in philosophy and its influence on contemporary scientific disciplines. Thinking Things Through offers a broad, historical, and rigorous introduction to the logical tradition in philosophy and its contemporary significance. It is unique among introductory philosophy texts in that it considers both the historical development and modern fruition of a few central questions. It traces the influence of philosophical ideas and arguments on modern logic, statistics, decision (...) theory, computer science, cognitive science, and public policy. The text offers an account of the history of speculation and argument, and the development of theories of deductive and probabilistic reasoning. It considers whether and how new knowledge of the world is possible at all, investigates rational decision making and causality, explores the nature of mind, and considers ethical theories. Suggestions for reading, both historical and contemporary, accompany most chapters. This second edition includes four new chapters, on decision theory and causal relations, moral and political theories, “moral tools” such as game theory and voting theory, and ethical theories and their relation to real-world issues. Examples have been updated throughout, and some new material has been added. It is suitable for use in advanced undergraduate and beginning graduate classes in philosophy, and as an ancillary text for students in computer science and the natural sciences. (shrink)

Words, Thoughts and Theories argues that infants and children discover the physical and psychological features of the world by a process akin to scientific inquiry, more or less as conceived by philosophers of science in the 1960s (the theory theory). This essay discusses some of the philosophical background to an alternative, more popular, “modular” or “maturational” account of development, dismisses an array of philosophical objections to the theory theory, suggests that the theory theory offers an undeveloped project for artificial intelligence, (...) and, relying on recent psychological work on causation, offers suggestions about how principles of causal inference may provide a developmental solution to the “frame problem”.

In everyday matters, as well as in law, we allow that someone’s reasons can be causes of her actions, and often are. That correct reasoning accords with Bayesian principles is now so widely held in philosophy, psychology, computer science and elsewhere that the contrary is beginning to seem obtuse, or at best quaint. And that rational agents should learn about the world from energies striking sensory inputs nerves in people—seems beyond question. Even rats seem to recognize the difference between correlation (...) and causation,1 and accordingly make different inferences from passive observation than from interventions. A few statisticians aside,” so do most of us. To square these views with the demands of computability, increasing numbers of psychologists and others have embraced a particular formalization, causal Bayes nets, as an account of human reasoning about and to causal connections.111 Such structures can be used by rational agents, including humans in so far as they are rational, to have degrees of belief in various conceptual contents, which they use to reason to expectations, which are realized or defeated by sensory inputs, which cause them to change their degrees of belief in other contents in accord with Bayes Rule, or some generalization of it. How is all of this supposed to be carried out? l. Representing Causal Structures The causal Bayes net framework adopted by a growing number of psychologists goes like this: Our representations of causal relations are captured in a graphical causal.

The claims of science and the claims of probability combine in two ways. In one, probability is part of the content of science, as in statistical mechanics and quantum theory and an enormous range of "models" developed in applied statistics. In the other, probability is the tool used to explain and to justify methods of inference from records of observations, as in every science from psychiatry to physics. These intimacies between science and probability are logical sports, for while we think (...) science aims to say what happens, what has happened, what will happen, what would happen if other things were to happen, what could and could not happen, what will nearly happen, or what will approximate what will happen, probability claims say none of these things, or at least none of them about the phenomena with which science is concerned. On that, at least, almost all philosophical interpreters of probability since DeMoivre agree, with whatever reluctance. Consider some examples. (shrink)

_Paradoxes from A to Z, Third edition_ is the essential guide to paradoxes, and takes the reader on a lively tour of puzzles that have taxed thinkers from Zeno to Galileo, and Lewis Carroll to Bertrand Russell. Michael Clark uncovers an array of conundrums, such as Achilles and the Tortoise, Theseus’ Ship, and the Prisoner’s Dilemma, taking in subjects as diverse as knowledge, science, art and politics. Clark discusses each paradox in non-technical terms, considering its significance and looking (...) at likely solutions. This third edition is revised throughout, and adds nine new paradoxes that have important bearings in areas such as law, logic, ethics and probability. Paradoxes from A to Z, Third edition is an ideal starting point for those interested not just in philosophical puzzles and conundrums, but anyone seeking to hone their thinking skills. (shrink)

Defensive harm is subject to both a proportionality and necessity constraint. In what follows I precisify, explain, and unify these two constraints. I argue that they express the very same moral demand, only at different levels of generality—specifically, the demand that an attacker not be made to bear more cost to avert their attack than they would be required to take on themselves.

A fictional consideration of the hazards life might hold if certain theories of mind were true. Originally given as an after dinner talk at the University of North Carolina Conference.

Data mining is on the interface of Computer Science and Statistics, utilizing advances in both disciplines to make progress in extracting information from large databases. It is an emerging field that has attracted much attention in a very short period of time. This article highlights some statistical themes and lessons that are directly relevant to data mining and attempts to identify opportunities where close cooperation between the statistical and computational communities might reasonably provide synergy for further progress in data analysis.

As the issue of assisted dying continues toward more expanded legal standing, we shift our primary focus from questions of patients' rights to the largely overlooked challenges that face physicians who elect to assist patients in ending their lives. Dr. Howard Grossman, a Manhattan internist and plaintiff in the unsuccessful New York lawsuit to the Supreme Court, came forward to say, “Anybody who has done it knows that it is a tremendous decision that you carry with you forever.”1 We focus (...) our attention on the psychological experience and philosophical conflicts faced by physicians engaged in physician-assisted dying. Based on those potential conflicts, we argue for a new model of the physician and patient relationship in assisted dying: a medical friendship. a. (shrink)

It is widely held that intuitive dualism—an implicit default mode of thought that takes minds to be separable from bodies and capable of independent existence—is a human universal. Among the findings taken to support universal intuitive dualism is a pattern of evidence in which “psychological” traits (knowledge, desires) are judged more likely to continue after death than bodily or “biological” traits (perceptual, physiological, and bodily states). Here, we present cross-cultural evidence from six study populations, including non-Western societies with diverse belief (...) systems, that shows that while this pattern exists, the overall pattern of responses nonetheless does not support intuitive dualism in afterlife beliefs. Most responses of most participants across all cultures tested were not dualist. While our sample is in no way intended to capture the full range of human societies and afterlife beliefs, it captures a far broader range of cultures than in any prior study, and thus puts the case for afterlife beliefs as evidence for universal intuitive dualism to a strong test. Based on these findings, we suggest that while dualist thinking is a possible mode of thought enabled by evolved human psychology, such thinking does not constitute a default mode of thought. Rather, our data support what we will call intuitive materialism—the view that the underlying intuitive systems for reasoning about minds and death produce as a default judgment that mental states cease to exist with bodily death.

Recent studies such as Thelen and Smith, Kelso, Van Gelder, Beer, and others have presented a forceful case for a dynamical systems approach to understanding cognition and adaptive behavior. These studies call into question some foundational assumptions concerning the nature of cognitive scientific explanation and the role of notions such as internal representation and computation. These are exciting and important challenges. But they must be handled with care. It is all to easy in this debate to lose sight of the (...) explanatorily important issues and to talk at cross purposes, courtesy of the various ways in which different theorists often concieve key terms.

This article will examine McCormick's moral epistemology both at the level of how human persons know values and disvalues, which hereinafter will be referred to as synderesis, and at the level of how human persons know the rightness and wrongness of an action, which hereinafter will be referred to as normative moral judgment. On the one hand, from this investigation it appears that McCormick operates with a dual moral epistemology, at least at the level of synderesis. This means that at (...) one point in time it appears that a significant shift may have occurred in his moral epistemology at the level of synderesis. This may also be true at the level of normative moral judgment. On the other hand, McCormick's moral epistemology may in fact be a synthesis, which is the product of development and maturity in his thought process. This article will articulate, examine, and analyse both moral epistemologies. The first moral epistemology is operative in McCormick's writing up until 1983. The second moral epistemology corresponds to McCormick's decision in 1983 to write primarily in the area of bioethics from a theological perspective. Since the year 1983 seems to be the pivotal time when these two moral epistemologies converge, I will refer to the first moral epistemology as “prior to 1983” and I will refer to the second moral epistemology as “after 1983.” Because of the numerous criticisms that surround McCormick's moral epistemology, and the ambiguity that it entails, McCormick needed to articulate his theoretical foundations clearly and develop them systematically and coherently. Numerous moral theologians called for him to do this, yet he never responded. A systematic understanding of McCormick's moral epistemology is not only necessary but crucial in examining various issues in bioethics. It is necessary because it is the basis of moral decision making. It is crucial because the life and death of individuals may hang in the balance. (shrink)

We argue that current discussions of criteria for actual causation are ill-posed in several respects. (1) The methodology of current discussions is by induction from intuitions about an infinitesimal fraction of the possible examples and counterexamples; (2) cases with larger numbers of causes generate novel puzzles; (3) "neuron" and causal Bayes net diagrams are, as deployed in discussions of actual causation, almost always ambiguous; (4) actual causation is (intuitively) relative to an initial system state since state changes are relevant, but (...) most current accounts ignore state changes through time; (5) more generally, there is no reason to think that philosophical judgements about these sorts of cases are normative; but (6) there is a dearth of relevant psychological research that bears on whether various philosophical accounts are descriptive. Our skepticism is not directed towards the possibility of a correct account of actual causation; rather, we argue that standard methods will not lead to such an account. A different approach is required. (shrink)

This article reports on research that examines newly qualified UK nurses’ experiences of implementing their ideals and values in contemporary nursing practice. Findings are presented from questionnaire and interview data from a longitudinal interpretive study of nurses’ trajectories over time. On qualification nurses emerged with a coherent and strong set of espoused ideals around delivering high quality, patient‐centred, holistic and evidence‐based care. These were consistent with the current UK nursing mandate and had been transmitted and reinforced throughout their ‘prequalification’ programmes. (...) The existence of professional and organisational constraints influenced their ability to implement these ideals and values once in practice. Data analysis revealed that within 2 years in practice the newly qualified nurses could be categorised as sustained idealists, compromised idealists, or crushed idealists. The majority experienced frustration and some level of ‘burnout’ as a consequence of their ideals and values being thwarted. This led to disillusionment, ‘job‐hopping’ and, in some cases, a decision to leave the profession. These data are explored and discussed to inform the question of whether the current nursing mandate is sustainable. (shrink)

In the movie, Memento, the hero, Leonard, suffers from a form of anterograde amnesia that results in an inability to lay down new memories. Nonetheless, he sets out on a quest to find his wife’s killer, aided by the use of notes, annotated polaroids, and body tattoos. Using these resources he attempts to build up a stock of new beliefs and to thus piece together the puzzle of his wife’s death. At one point in the movie, a character exasperated by (...) Leonard’s lack of biological recall, shouts: “YOU know? What do YOU know. YOU don’t know anything. In 10 minutes time YOU won’t even know you had this conversation” Leonard, however, believes that he does, day by day, come to know new things. But only courtesy of those photos, tattoos, tricks and ploys. Who is right?These are the kinds of question addressed at length in the paper ‘The Extended Mind’. Is the mind contained in the head? Or does the notion of thought allow mental processes to inhere in extended systems of body, brain and aspects of the local environment? The answer, we claimed, was that mental states, including states of believing, could be grounded in physical traces that remained firmly outside the head. As long as a few simple conditions were met, Leonard’s notes and tattoos could indeed count as new additions to his store of long-term knowledge and dispositional belief. In the present treatment I revisit this argument, defending our strong conclusion against a variety of subsequent observations and objections. In particular, I look at objections that rely on a contrast between the intrinsic content of neural symbols and the merely derived content of external inscriptions, at objections concerning the demarcation of scientific domains via natural kinds, and at objections concerning the ultimate locus of agentive control and the nature of perception versus introspection. I also mention a possible alternative interpretation of the argument as a reductio of the very idea of the mind as an object of scientific study. This is an interesting proposal. (shrink)

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

Two ideas shape the epistemology of testimony. One is that testimony provides a unique kind of knowledge. The other is that testimonial knowledge is a social achievement. In traditional terms, those who affirm these ideas are anti-reductionists, and those who deny them are reductionists. There is increasing interest, however, in the possibility of affirming these ideas without embracing anti-reductionism. Thus, Sanford Goldberg uses the idea of epistemic buck-passing to argue that even reductionists can accept the uniqueness of testimonial knowledge, and (...) Jennifer Lackey gives both speaker and hearer an essential role in testimonial justification, rejecting both reductionism and anti-reductionism in favor of what she calls dualism. After distinguishing a weaker and a stronger notion of buck-passing, we show how anti-reductionists can use the stronger notion to motivate their position, and to answer Goldberg’s and Lackey’s challenges.

In his meditation on Emerson's self-reliance, George Kateb argues that Emerson's entrance into antislavery politics, particularly his calls for collective mobilization, constitutes a “deviation from his theory of self-reliance, not its transformation.” Though Emerson often imagines a self-reliance that can lead to action, his descriptions of the fundamental attitude of the self towards the world suggest passivity, attention, and waiting. Because he rules out logical or teleological sources for inspiration, his conception of self-reliance is fundamentally at odds with progressivist narratives (...) of history. His sense of “entranced waiting” flirts with an anarchic potentiality that he must reject in order to call for social solidarity and progressive action against slavery. In “Bartleby, the Scrivener,” Melville takes the radical outsidedness of self-reliance to its conclusion, transforming Emersonian waiting into Bartleby's catatonic stillness. Emerson's waiting for inspiration becomes the copyist's quiet demand that his employer wait with him rather than use charitable actions to free himself from the burden Bartleby imposes. Bartleby obstructs the lawyer's ideas of improvement as well as his conception of himself as a moral agent in a world of moral possibility. Simone Weil provides a similar version of a quietist waiting with. To an ungenerous “active searching” she opposes a fundamental generosity, a “waiting or attentive and faithful immobility” through which one is able to recognize “that the sufferer exists.” For Weil, as for Melville, there is no passage from such a recognition to a conception of history as progress. The sufferer is not a problem to be solved within a narrative of social improvement but the source of an unlimited and impossible obligation. (shrink)

The editorial stance of this book is that mysticism and science offer a way forward here, but only if they abandon the idol of a single logical synthesis and acknowledge the diversity of different ways of knowing. The contributors from disciplines as diverse as music, psychology, mathematics and religion, build a vision that honours diversity while pointing to an implicit unity.

Autobiography is a distinctive and valuable kind of reasoning towards ethical knowledge. But how can autobiography be ethical reasoning? I distinguish four ways in which autobiography can be merely involved in reasoning: as clue to authorial intentions; as container for conventional reasoning; as historical data; and as thought experiment. I then show how autobiography can itself be reasoning by investigating its generic form. Autobiographies are particular, enabling vivid display of and education in value-suffused perception. They are diachronic, enabling critique by (...) ironic contrast. And they are compositional, enabling sense-making by placing in a temporal structure. But these features don’t distinguish autobiographies from novels. Should we therefore accept a deflationary account of a fourth generic feature of autobiographies, that they are self-reflective? I instead pursue a more ambitious account of self-reflection and the distinctively autobiographical reasoning it enables, involving a realism constraint, a reflexive explanation constraint, and unique address to first-person problems of the self. I conclude with an interpretation of an example work of autobiographical reasoning, Siegfried Sassoon’s Memoirs of George Sherston, against the idea that self-owning is necessary to the good human life.

Increased productivity may have negative impacts on farm animal welfare in modern animal production systems. Efficiency gains in production are primarily thought to be due to the intensification of production, and this has been associated with an increased incidence of production diseases, which can negatively impact upon FAW. While there is a considerable body of research into consumer attitudes towards FAW, the extent to which this relates specifically to a reduction in production diseases in intensive systems, and whether the increased (...) incidence of diseases represents a barrier to consumer acceptance of their increased use, requires further investigation. Therefore a systematic review of public attitudes towards FAW was conducted, with a specific focus on production diseases in intensive systems. Four databases were searched to identify relevant studies. A screening process, using a set of pre-determined inclusion criteria, identified 80 studies, with the strength of evidence and uncertainty assessed for each. A thematic analysis led to the identification of 6 overarching themes constructed from 15 subthemes. The results demonstrate that the public are concerned about FAW in modern production systems. Concern varied in relation to age, gender, education and familiarity with farming. Naturalness and humane treatment were central to what was considered good welfare. An evidence gap was highlighted in relation to attitudes towards specific production diseases, with no studies specifically addressing this. However, the prophylactic use of antibiotics was identified as a concern. A number of dissonance strategies were adopted by consumers to enable guilt free meat consumption. (shrink)
