We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

The target article makes a compelling case for the idea that agents rely on the world for external memory in fast-paced perceptual tasks. As I argue, however, agents also rely on the external environment for computational hardware that helps to keep cognitive computations tractable. Hence the external world provides not only memory for computations involving perceptual system actions, but it provides domain-level actions that figure in cognitive computations as well.

Cognitive organisms have three rather different techniques for intelligently regulating their intake of environmental information. In order of the time needed to uncover information they are: 1. control of attention: within an image produced by a given sensor certain elements can be selected for additional processing; 2. control of gaze: the orientation and resolution (center of foveation) of the sensor can be regulated to create a new image; 3. control of activity: certain non-perceptual actions can be performed to increase the (...) probability of unearthing salient information that currently is unavailable, hard to detect, or hard to compute.

Although Kirsh and Maglio's work on ?epistemic? and ?pragmatic? action provides us with some valuable insights, the degree of overlap, or interpenetration, between these two terms suggests that there is something problematic in the distinction. On one analysis, it might be suggested that epistemic and pragmatic actions are not both ?types of action? in the same sense and, perhaps, that there may not be a strong sense in which ?pragmatic actions? are a type of action at all. Things are (...) further complicated by definitional issues. In the case of ?epistemic action?, if the conception of what counts as such is too wide-ranging the term ceases to be useful. (shrink)

Reverence is an ancient virtue that survives among us in half-forgotten patterns of civility and moments of inarticulate awe. Reverence gives meaning to much that we do, yet the word has almost passed out of our vocabulary.Reverence, says philosopher and classicist Paul Woodruff, begins in an understanding of human limitations. From this grows the capacity to be in awe of whatever we believe lies outside our control -- God, truth, justice, nature, even death. It is a quality of character (...) that is especially important in leadership and in teaching, although it figures in virtually every human relationship. It transcends religious boundaries and can be found outside religion altogether.Woodruff draws on thinking about this lost virtue in ancient Greek and Chinese traditions and applies lessons from these highly reverent cultures to today's world. The book covers reverence in a variety of contexts -- the arts, leadership, teaching, warfare, and the home -- and shows how essential a quality it is to a well-functioning society.First published by Oxford University Press in 2001, this new edition of Reverence is revised and expanded. It contains a foreword by Betty Sue Flowers, Distinguished Teaching Professor Emeritus at the University of Texas at Austin, a new preface, two new chapters -- one on the sacred and one on compassion -- and an epilogue focused on renewing reverence in our own lives.

The book provides an analysis of a key notion in our lives, causation: what its nature is; how we should characterise it in language, how it relates to laws of nature, how causes differ from their effects and why they tend to occur earlier than their effects.

The Gamer’s Dilemma challenges us to justify the moral difference between enacting virtual murder and virtual child molestation in video games. The Dilemma relies for its argumentative force on the claim that there is an intuitive moral difference between these acts, with the former intuited as morally acceptable and the latter as morally unacceptable. However, there has been no empirical investigation of these claims. To explore these issues, we developed an experimental survey study in which participants were asked to reflect (...) on imaginary video game scenarios as part of a 2 (undertake virtual murder or molestation) X 2 (against an adult or child) X 2 (in a high or low realism virtual environment) factorial design. We found that there was a significant difference between people’s views about virtual murder and virtual molestation. Whether the virtual act was performed against an adult or child was non-significant in most conditions, whereas whether it was performed in a high or low realism virtual environment was significant in most conditions. Gender did not impact these results, whereas perceived gaming experience, hours of video game play per week, and integrity did. These results provide an empirical grounding for future discussions of the Gamer's Dilemma. (shrink)

This undergraduate textbook introduces some fundamental issues in philosophy of science for students of philosophy and science students. The book is divided into two parts. Part 1 deals with knowledge and values. Chap. 1 presents the classical conception of knowledge as initiated by the ancient Greeks and elaborated during the development of science, introducing the central concepts of truth, belief and justification. Aspects of the quest for objectivity are taken up in the following two chapters. Moral issues are broached in (...) Chap. 4, which discusses some aspects of the use and abuse of science, taking up the responsibilities of scientists in properly conducting their business and decision-makers in their concerns with the import of science for society. Part 2 contrasts the view of scientific progress as the rejecting of old hypotheses and theories and replacing them with new ones, represented by Karl Popper, with the conception of progress as accumulating knowledge, saving as much as possible from older theories, represented by Pierre Duhem. A concluding chapter defends the natural attitude of taking the theories of modern science to be literally true, i.e. realism, in the face of arguments drawn partly from the history of scientific progress in criticism of this stance.

It is well-known that the entangled quantum state of a composite object cannot be reduced to the states of its parts. This quantum holism provides a peculiar challenge to formulate an appropriate mereological model: When a system is in an entangled state, which objects are there on the micro and macro level, and which of the objects carries which properties? This paper chooses a modeling approach to answer these questions: It proceeds from a systematic overview of consistent mereological models for (...) entangled systems and discusses which of them is compatible with the quantum mechanical evidence (where quantum states are understood realistically). It reveals that entangled quantum systems neither describe undivided wholes nor objects that stand in irreducible relations. The appropriate model assumes that the entangled property is an irreducible non-relational plural property carried collectively by the micro objects, while there is no macro object. In this sense, quantum holism is an instance of property holism, not of object holism. (shrink)

This paper develops a trivalent semantics for indicative conditionals and extends it to a probabilistic theory of valid inference and inductive learning with conditionals. On this account, (i) all complex conditionals can be rephrased as simple conditionals, connecting our account to Adams's theory of p-valid inference; (ii) we obtain Stalnaker's Thesis as a theorem while avoiding the well-known triviality results; (iii) we generalize Bayesian conditionalization to an updating principle for conditional sentences. The final result is a unified semantic and probabilistic (...) theory of conditionals with attractive results and predictions. (shrink)

Threats to the stability of liberal democracies are of obvious contemporary import. Concern with stability runs through John Rawls’s work. The stability that concerned him was that of fundamental terms of cooperation. Rawls long believed that the terms which would be stable were his two principles, but he eventually conceded that even a well-ordered society was more likely to be characterized by “justice pluralism” than by consensus on his own conception of justice. Contemporary liberal democracies, too, are divided about what (...) justice demands. I believe Rawls’s treatment of stability can help us understand the conditions under which fundamental terms of cooperation can be stable under non-ideal conditions such as ours. But because Rawls never worked through the consequences of his concession, his view needs to be developed before we can draw on it. Rawls’s treatment makes use of elementary game theory. Thus in _Theory of Justice_ he said -- and in _Political Liberalism_ he implied -- that stability would result from citizens with a sense of justice “playing” strategies which combined for what was, in effect, a Nash equilibrium. I argue that his concession requires a new conception of stability and implies that Rawls cannot appeal to a Nash equilibrium to show how stability would be maintained. His concession therefore forces open a troubling gap in his analysis. I fill that gap by proposing a weaker equilibrium concept that serves Rawlsian purposes. I conclude with what this project suggests for challenges facing the fragile liberal democracies of our own time. (shrink)

In their article ’Is Pregnancy a Disease? A Normative Approach’, Anna Smajdor and Joona Räsänen contend that, on several of the most prominent accounts of disease, pregnancy should be considered a disease. More specifically, of the five accounts they discuss, each renders pregnancy a disease or suffers serious conceptual problems otherwise. They take issue specifically with the dysfunction account of disease and argue that it suffers several theoretical difficulties. In this response, we focus on defending the dysfunction account against their (...) main objections and show why a version of the dysfunction account is viable on account of the indispensability of normativity in biology and medicine. After disarming their main objections to the dysfunction account, we briefly respond to their treatment of the normality of pregnancy and then draw a distinction between adverse symptoms and underlying causes to show why even though pregnancy may have ’disease-like’ features, it is not a disease.

This collection of papers makes a step towards increased dialogue among philosophical liberals and their theological, sociological and legal critics. The text should be significant for those concerned with the place of religion within a liberal society.

This paper considers the question of “atheism” as it arises in Hume’s _Dialogues_. It argues that the concept of “atheism” involves several signficiant ambiguities that are indicative of philosophical and interpretive disagreements of a more substantial nature. It defends the view that Philo’s general sceptical orientation accurately represents Hume’s own “irreligious” and “atheistic” commitments, both in the _Dialogues_ and in his other (“earlier”) writings. While Hume was plainly a “speculative atheist”, his “practical atheism” was targeted more narrowly against “superstition” - (...) as opposed to deism or religion of a more “philosophical” kind.

Davidson’s account of singular causal statements as expressing relations between events together with his views on event identity lead to inferences involving causal statements which many of his critics find counterintuitive. These are sometimes said to be avoided on Kim’s view of events, in terms of which this line of criticism is often formulated. It is argued that neither Davidson nor Kim offer a satisfactory account of events - an essential prerequisit for the relational theory - and an account of (...) singular causal statements in terms of a modal sentential connective is advocated in place of the relational view. Such an account suffices to block the counter-intuitive inferences without needing to resort to a theory of events. It is suggested that a theory of events might be built upon a connective account of singular causal statements, but no such theory is presented here. (shrink)

This introduction provides a brief overview of the issues and arguments that arise in Hume's _Dialogues concerning Natural Religion_ (1779). It also provides a few brief comments relating to the historical context in which this text should be interpreted , as well as an account of the place of the _Dialogues_ in relation to Hume's other philosophical works.

Broadly speaking, this is a book about truth and the criteria thereof. Thus it is, in a sense, a book about justification and rationality. But it does not purport to be about the notion of justification or the notion of rationality. For the assumption that there is just one notion of justification, or just one notion of rationality, is, as the book explains, very misleading. Justification and rationality come in various kinds. And to that extent, at least, we should recognize (...) a variety of notions of justification and rationality. This, at any rate, is one of the morals of Chapter VI. This book, in Chapters I-V, is mainly concerned with the kind of justification and rationality characteristic of a truth-seeker, specifically a seeker of truth about the world impinging upon the senses: the so-called empirical world. Hence the book's title. But since the prominent contemporary approaches to empirical justification are many and varied, so also are the epistemological issues taken up in the following chapters. For instance, there will be questions about so-called coherence and its role, if any, in empirical justification. And there will be questions about social consensus (whatever it is) and its significance, or the lack thereof, to empirical justification. Furthermore, the perennial question of whether, and if so how, empirical knowledge has so-called founda­ tions will be given special attention. (shrink)

Genome editing enables very accurate alterations to DNA. It promises profound and potentially disruptive changes in healthcare, agriculture, industry, and the environment. This paper presents a multidisciplinary analysis of the contemporary development of genome editing and the tension between continuity and change. It draws on the idea that actors involved in innovation are guided by “sociotechnical regimes” composed of practices, institutions, norms, and cultural beliefs. The analysis focuses on how genome editing is emerging in different domains and whether this marks (...) continuity or disruption of the established biotechnology regime. In conclusion, it will be argued that genome editing is best understood as a technology platform that is being powerfully shaped by this existing regime but is starting to disrupt the governance of biotechnology. In the longer term is it set to converge with other powerful technology platforms, which together will fundamentally transform the capacity to engineer life. (shrink)

This study examined the historical perspectives of eleven emergent bilingual and bilingual students at two middle schools. Data analysis revealed that the participants’ perspectives on U.S. history reflected three schematic narrative templates focused on nation-building, equality, and discrimination. The participants primarily employed the (in)equality narratives when discussing aspects of U.S. history directly linked to their identities. The findings add to the extant research on student historical perspectives and use of schematic narrative templates. The findings further suggest that engaging (emergent) bilingual (...) students in examining multiple perspectives and conducting critical history inquiry can contribute to notions of culturally and linguistically responsive social studies instruction.

How can the Biblical God be the Lord and King who, being typically unseen and even self-veiled at times, authoritatively leads people for divine purposes? This article’s main thesis is that the answer is in divine moral leading via human moral experience of God (of a kind to be clarified). The Hebrew Bible speaks of God as ‘king,’ including for a time prior to the Jewish human monarchy. Ancient Judaism, as Martin Buber has observed, acknowledged direct and indirect forms of (...) divine rule and thus of theocracy. This article explores the importance of divine rule as divine direct leading, particularly in moral matters, without reliance on indirect theocracy supervised by humans. It thus considers a role for God as Über-King superior to any human king, maintaining a direct moral theocracy without a need for indirect theocracy. The divine goal, in this perspective, is a universal commonwealth in righteousness, while allowing for variation in political structure. The article identifies the importance in the Hebrew Bible of letting God be God as an Über-King who, although self-veiled at times, leads willing people directly and thereby rules over them uncoercively. It also clarifies a purpose for divine self-veiling neglected by Buber and many others, and it offers a morally sensitive test for unveiled authenticity in divine moral leading. (shrink)

Over the past two decades, Philip Pettit has consistently argued for an understanding of “republican” liberty in terms of nondomination. Yet in his major published studies, he has almost nothing to say about markets, nor about the economy more generally. I contend that this is a seriously problematic omission, insofar as markets represent a major problem for republican views of freedom. In short: if freedom requires the absence of the mere possibility of arbitrary interference (as Pettit maintains), then the widespread (...) existence of markets indicates that on a republican view the vast majority of people in the world today exist in the dominated position of slaves. As a result, Pettit cannot adopt the “complacency” towards market transactions that he officially avows. But in turn, we ought to be highly skpetical that the republican account of freedom is a viable one. (shrink)

Marcus Willaschek’s new book Kant on the Sources of Metaphysics: The Dialectic of Pure Reason is a penetrating analysis of the Transcendental Dialectic of Kant’s Critique of Pure Reason. In his comments, the author first raises some questions concerning the structure of the Transcendental Dialectic and then proposes that looking at the second Critique and continuing on into the third Critique will reveal more roles for the idea of God in Kant’s reconstruction of traditional metaphysics than Willaschek’s treatment suggests.

Classical atoms—“part-less, ontologically irreducible simples” as the conference flyer puts it—are not the atoms of modern chemistry and analogies with the latter can be construed in various ways. They have figured in the historical development of concepts of chemical affinity but without, as Alan Chalmers and I have independently argued, making any significant contribution to empirically justified theories. A purely combinatorial conception of the formation of compounds by juxtaposing atoms is associated with Daltonian atomism. I review the merits of this (...) idea as a solution to problems posed by developments in early nineteenth century chemistry and go on to suggest that subsequent developments in chemistry are as much in agreement with ideas associated with Aristotle as with the ancient atomists, if not more so. The basic issues can be understood without getting involved in detailed chemistry and I hope what I have to say will be of interest to philosophers concerned with the metaphysics of matter but with no special knowledge of chemistry.

Prior left us with a problem which he stated in the following way: ‘Very roughly, it would seem that countable “things” are made or grow from bits of stuff, or from other countable “things”, that are already there. The precise logic of this process hasn’t been worked out yet, and until it has been, it seems likely that any tensed predicate logic can only be provisional in character.’ Although I disagree with much of the philosophy of time underlying Priorean tense (...) logic, the problem of presenting a coherent view of ‘countable things’ and ‘bits of stuff’ within a framework accommodating temporal reference and modal expressions along broadly the lines Prior proposed remains an interesting one. The present paper sketches a general framework within which more specific questions raised by this general issue can be addressed, and makes a number of tentative suggestions without, however, proceeding so far as to settle on and develop a definite logical theory.
