This paper considers the implications of David Marr's computational theory of vision for the issues of individualism and methodological solipsism. A recent argument that the theory is nonindividualistic is shown to be similar to Gibson's arguments for "direct perception." The paper argues that a complete analysis of Marr's theory must take into account Marr's rejection of Gibson's approach, and that such an analysis shows Marr's theory to be consistent with methodological (...) solipsism as a research strategy.

According to one brand of 'externalism', cognitive theories should individuate mental content 'widely'--that is, partly in terms of environmental features. David Marr's theory of vision is often cited in support of this view. Many philosophers (most notably, Tyler Burge) regard it as a prime example of a fruitful cognitive theory that widely individuates the representations it posits. I argue that, contrary to popular belief, Marr's theory does not presuppose an externalist view of mental (...) content. (shrink)

The debate concerning the individuating role of the external environment in propositional content has turned to Marr’s computational theory of vision for either verification or disproof. Although not all the relevant arguments concerning the determining role of environmental constraints that Marr invokes in his visual account may succeed, the paper argues that Marr divides his computational explanation into two parts, the information processing “what” and the constraint introducing “why” aspect. It is the second part where separate claims concerning (...) the necessity and sufficiency of constraints are advocated, and initiate a specific computational process. The above explanation becomes subordinate to a conception of inference that closely resembles deduction. (shrink)

David Marr's theory of vision has been widely cited by philosophers and psychologists. I have three projects in this paper. First, I try to offer a perspicuous characterization of Marr's theory. Next, I consider the implications of Marr's work for some currently popular philosophies of psychology, specifically, the "hegemony of neurophysiology view", the theories of Jerry Fodor, Daniel Dennett, and Stephen Stich, and the view that perception is permeated by belief. In the last (...) section, I consider what the phenomenon of vision must be like for Marr's project to succeed. (shrink)

A large body of research in computational vision science stems from the pioneering work of David Marr. Recently, Patricia Kitcher and others have criticized this work as depending upon optimizing assumptions, assumptions which are held to be inappropriate for evolved cognitive mechanisms just as anti-adaptationists (e.g., Lewontin and Gould) have argued they are inappropriate for other evolved physiological mechanisms. The paper discusses the criticism and suggests that it is, in part, misdirected. It is further suggested that the criticism (...) leads to interesting questions about how one formulates constraints--across "levels of organization" and disciplinary boundaries--on one's models of complex systems, such as human vision. (shrink)

A central aspect of the computational theory of vision developed by Marr and his coworkers is the use made of contingent regularities in the physical environment to explain how the visual system determines the shape and location of objects in the world on the basis of the spatial organization of the retinal image. Marr (1982) refers to these environmental regularities as “natural constraints” and “physical assumptions.” In this paper I am concerned with recent arguments concerning the implications of (...) this feature of Marr’s theory for understanding psychological explanation. Burge (1986) claims that Marr’s use of natural constraints shows the theory to be nonindividualistic, in the sense that the individuation of psychological states depends essentially on the objects and conditions of the world external to the subject. While it does capture an important aspect of Marr’s theory, Burge’s account is misleadingly incomplete. To see this it is useful to compare the issue of individualism with the question whether the theory is compatible with methodological solipsism as a research strategy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"Magic Buffalo" and Berkeley's Theory ofVision: Learning in Society David M. Levy Introduction Berkeley's Theory of Vision contains the remarkable claim that the perception ofdistance is learned by experience. This thesis is rooted in Berkeley's doctrine that the physical basic of optical perception is angular. An impression of angle? impacts upon the optic nerve. The interpretative problem confronting an individual is that of reconstructing two (...) pieces ofinformation, distance d and magnitude m, from one datum T. Let the ratio ofm/d form arctan T. How do we come to distinguish between the pair m1,d1 and the pair m2,d2 when m^d 1 = m2/d2? How do we distinguish big objects at a distance from small objects up close? The evidence Berkeley provides for this thesis is of a funny sort. He gives examples that we do, in fact, distinguish large distant objects from small near objects. Since the arctan of the pair m1, d 1 is by hypothesisthe sameas thatofthepairm2, d2thenrecognizingdistance must be alearned abihty. We cannotextractd and m from? alone. The proper interpretation ofBerkeley's philosophy ofscience is a matter of considerable debate.1 Nonetheless, as a working theorist of visual perception he is afairly simple-minded falsificationist. Here is what he says: find a person born blind who comes by surgery to see. If that person can distinguish at a glance big distant objects from small near objects, 111 amend my theory.2 The literature on Berkeley's Theory ofVision can be fairly said to bifurcate between those who "see" the argument and those who don't. Berkeley's most important eighteenth century disciple, Adam Smith, extended Berkeley's teaching to encompass the remarkable claim that we learn to perceive our economic interest (Levy 1992a, 1992b). The negative reaction to Berkeley's theory starts in 1842 with Samuel Bailey who pronounced himself mystified by the very claim that we learn to perceive distance. The debate between Bailey and John Stuart Mill, a debate which has twentieth century counterparts, has all the characteristics ofpeople talking past each other. Volume XLX Number 1 223 DAVID M. LEVY The missing social dimension The problem, as I see it, with Berkeley's proposed critical test—stipulating his own doctrine—is that a blind person would grow up in a sighted community. Perhaps, if he grew up in a blind community, and most of the community became sighted at the same time he did, all the community might be able to perceive distance. The problem with Berkeley's test is that ifhe himself is correct about the importance ofheuristics in making the visual distinctions, the fate of one individual is somewhat beside the point. One individual surely cannot create the necessary heuristics. This learning requires some evolutionary social process. Thus, while Berkeley's thesis requires some claim about some verybasicsocial epistemology(Fuller 1988), his proposed test, asking about a blind person growing up in a community silently presumed to be sighted, does not take into account the social dimension oflearning. Having said this, it is easy to think ofa better test for Berkeley's theoryofvision. Let us find an entire community where life takes place without the visual perception of great distance. Take any individual from this community and ask Berkeleian questions. Now, we know the answer becausejust such a dialogue was reported thirtyyears ago. One society which fulfils the test criterion is that ofthe BaMbuti people who lived their life in a very dense African forest. The American anthropologist Colin Turnbull took his friend from the BaMbuti, Kenge, to the top of a hill. Here is TurnbuH's famous report: Then he saw the buffalo, still grazing lazily several miles away, far downbelow. He turned to me and said, "Whatinsects are those?" At first I hardly understood; then I realized that in the forest the range of vision is so limited that there is no great need to make an automatic allowance for distance when judging size. Out here in the plains, however, Kenge was looking for the first time Over apparently unending miles of unfamiliar grasslands, with not a tree worth the name to give him any basis for comparison. The same thing happened later on... (shrink)

Thirty years after the publication of Marr's seminal book Vision the papers in this topic consider the contemporary status of his influential conception of three distinct levels of analysis for information-processing systems, and in particular the role of the algorithmic and representational level with its cognitive-level concepts. This level has been downplayed or eliminated both by reductionist neuroscience approaches from below that seek to account for behavior from the implementation level and by Bayesian approaches from above that seek (...) to account for behavior in purely computational-level terms.

Most of the New Theory of Vision is an argument for a negative answer to Molyneux's question.// re primacy of vision in spatial perception: "most rational philosopher on this topic is Berkeley, whose New Theory of Vision presents in cogent detail the argument" (from Bennett 1966, p. 30, in note cites 41ff.).// Berkeley's criticisms of Locke: "If we really abstract from colour and hardness and all that 'belongs to sensation', so far from being left with (...) 'pure' notions of extension and figure, we are left with nothing but words emptied of meaning" (from Strawson 1966, p. 61). (shrink)

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

"My work has had nothing to do with gay liberation," Michel Foucault reportedly told an admirer in 1975. And indeed there is scarcely more than a passing mention of homosexuality in Foucault's scholarly writings. So why has Foucault, who died of AIDS in 1984, become a powerful source of both personal and political inspiration to an entire generation of gay activists? And why have his political philosophy and his personal life recently come under such withering, normalizing scrutiny by commentators as (...) diverse as Camille Paglia, Richard Mohr, Bruce Bawer, Roger Kimball, and biographer James Miller? David M. Halperin's Saint Foucault is an uncompromising and impassioned defense of the late French philosopher and historian as a galvanizing thinker whose career as a theorist and activist will continue to serve as a model for other gay intellectuals, activists, and scholars. A close reading of both Foucault and the increasing attacks on his life and work, it explains why straight liberals so often find in Foucault only counsels of despair on the subject of politics, whereas gay activists look to him not only for intellectual inspiration but also for a compelling example of political resistance. Halperin rescues Foucault from the endless nature-versus-nurture debate over the origins of homosexuality ("On this question I have absolutely nothing to say," Foucault himself once remarked) and argues that Foucault's decision to treat sexuality not as a biological or psychological drive but as an effect of discourse, as the product of modern systems of knowledge and power, represents a crucial political breakthrough for lesbians and gay men. Halperin explains how Foucault's radical vision of homosexuality as a strategic opportunity for self-transformation anticipated the new anti-assimilationist, anti-essentialist brand of sexual identity politics practiced by contemporary direct-action groups such as ACT UP. Halperin also offers the first synthetic account of Foucault's thinking about gay sex and the future of the lesbian and gay movement, as well as an up-to-the-minute summary of the most recent work in queer theory. "Where there is power, there is resistance," Michel Foucault wrote in The History of Sexuality, Volume I. Erudite, biting, and surprisingly moving, Saint Foucault represents Halperin's own resistance to what he views as the blatant and systematic misrepresentation of a crucial intellectual figure, a misrepresentation he sees as dramatic evidence of the continuing personal, professional, and scholarly vulnerability of all gay activists and intellectuals in the age of AIDS.

This volume offers a carefully argued, compelling theory of bioethics while eliciting practical implications for a wide array of issues including medical assistance-in-dying, the right to health care, abortion, animal research, and the definition of death. The authors' dual-value theory features mid-level principles, a distinctive model of moral status, a subjective account of well-being, and a cosmopolitan view of global justice. In addition to ethical theory, the book investigates the nature of harm and autonomous action, personal identity (...) theory, and the 'non-identity problem' associated with many procreative decisions. Readers new to particular topics will benefit from helpful introductions, specialists will appreciate in-depth theoretical explorations and a novel take on various practical issues, and all readers will benefit from the book's original synoptic vision of bioethics. This title is also available as Open Access on Cambridge Core. (shrink)

If infinitesimal numbers are ruled out, and we wish to maintain an algebra, then we rule out infinite numbers. This implication of Berkeley's argumenthas a dramatic implication for our understanding ofthe history ofideas about rule-directed action.

There are four pieces to my argument. First, we consider Berkeley's statementofwhat we shall call his doctrine ofstrict finitism in perception.9 Berkeley puts forward two postulates: 1) there exists some minimum perceptible quantity, and 2) distance is not perceived directly but by experience. Second, we define strict finitism and demonstrate that it translates into the claim that perception is fuzzy in a technical sense. If Berkeleian perception is fuzzy, then some modern criticism of Berkeley's strict finitism is based upon a simple misunderstandingofthe propertiesoffuzzyrelations. Thisis quite easy to set right. (Getting right the doctrine of those who implicitly take perception to be fuzzy—Adam Smith is my prime candidate—will be muchharder.)Third, wereconsiderBerkeley's dispute withMandeville on the role ofinfinite gain in choice. Here, we find Mandeville putting forward the Berkeleian position that if infinite amounts mattered, people would not behave as they do. Berkeley's position against Mandeville, however, seems to depend upon the supposition that infinite distance is sensible.10 Earlier, however, the position that Mandeville argued for was defended by Berkeley.

I argue that conscious visual experience consists in a direct and noninferential grasp of the way one’s current perceptual contact with the environment poises one to pursue various intentional plans, goals and projects. I show that such a view of visual consciousness is supported by current work in cognitive neuroscience, affords a compelling account of colour perception, and suggests a way to bridge the ‘explanatory gap’ between consciousness and the language of the natural sciences. In chapter 1, I examine the (...) reasoning that leads to the appearance of an explanatory gap between the phenomenal and the physical in more detail, and set out the constraints on a solution that our discussion of the problem has imposed. I then sketch the two rival takes on the relationship between perception and action mentioned above – adjudicating between these two theories is the task of the next two chapters, and is a recurring theme throughout. Chapter 2 moves on to discuss some recent work in the neuropsychology of vision and what it might suggest about the functional role of conscious vision, and the first half of chapter 3 considers two puzzle cases concerning colour perception. Each of these discussions turns out to constitute a source of support for the actionspace view that visual perception consists in a grasp of the practical consequences of sensation, and the second half of chapter 3 sets out this view and responds to an initial range of questions and objections it might face. Chapter 4 illustrates our view via a discussion of colour perception, and chapter 5 discusses the type of grasp of practical consequences that is necessary for perceptual sensitivity to issue in conscious experience. By chapter 6, we are in a position to see how the action-space approach can help close the explanatory gap for phenomenal consciousness, and our final chapter sets out how I think this should be done. I conclude with a brief discussion of further questions and prospects for the action-space approach. (shrink)

In the late 1960s and early 1970s David Marr produced three astonishing papers in which he gave a detailed account of how the fine structure and known cell types of the cerebellum, hippocampus and neocortex perform the functions that they do. Marr went on to become one of the main founders of Computational Neuroscience. In his classic work 'Vision' he distinguished between the computational, algorithmic, and implementational levels, and the three early theories concerned implementation. However, they were produced (...) when Neuroscience was in its infancy.Now that so much more is known, it is timely to revisit these early theories to see to what extent they are still valid and what needs to be altered to produce viable theories that stand up to current evidence. This book brings together some of the most distinguished scientists in their fields to evaluate Marr's legacy. (shrink)

"Legend is overdue for replacement, and an adequate replacement must attend to the process of science as carefully as Hull has done. I share his vision of a serious account of the social and intellectual dynamics of science that will avoid both the rosy blur of Legend and the facile charms of relativism.... Because of [Hull's] deep concern with the ways in which research is actually done, Science as a Process begins an important project in the study of science. (...) It is one of a distinguished series of books, which Hull himself edits."—Philip Kitcher, Nature "In Science as a Process, [David Hull] argues that the tension between cooperation and competition is exactly what makes science so successful.... Hull takes an unusual approach to his subject. He applies the rules of evolution in nature to the evolution of science, arguing that the same kinds of forces responsible for shaping the rise and demise of species also act on the development of scientific ideas."—Natalie Angier, New York Times Book Review "By far the most professional and thorough case in favour of an evolutionary philosophy of science ever to have been made. It contains excellent short histories of evolutionary biology and of systematics (the science of classifying living things); an important and original account of modern systematic controversy; a counter-attack against the philosophical critics of evolutionary philosophy; social-psychological evidence, collected by Hull himself, to show that science does have the character demanded by his philosophy; and a philosophical analysis of evolution which is general enough to apply to both biological and historical change."—Mark Ridley, Times Literary Supplement "Hull is primarily interested in how social interactions within the scientific community can help or hinder the process by which new theories and techniques get accepted.... The claim that science is a process for selecting out the best new ideas is not a new one, but Hull tells us exactly how scientists go about it, and he is prepared to accept that at least to some extent, the social activities of the scientists promoting a new idea can affect its chances of being accepted."—Peter J. Bowler, Archives of Natural History "I have been doing philosophy of science now for twenty-five years, and whilst I would never have claimed that I knew everything, I felt that I had a really good handle on the nature of science, Again and again, Hull was able to show me just how incomplete my understanding was.... Moreover, [Science as a Process] is one of the most compulsively readable books that I have ever encountered."—Michael Ruse, Biology and Philosophy. (shrink)

Volume 6 of _The Collected Works of Eric Voegelin_ offers the first translation of the full German text of _Anamnesis_ published in 1966. The previous English edition, translated by Gerhart Niemeyer, focused largely on the sections of _Anamnesis_ dealing directly with Voegelin's philosophy of consciousness. It omitted some of the extensive historical studies on which the philosophy of consciousness was based. To properly understand Voegelin's work, however, it is essential to give equal weight to the empirical as well as the (...) philosophical aspects. This complete version of _Anamnesis_ captures the full integrity of his vision. It is at once scientific, in the sense of fidelity to the demands of historiographic scholarship, and philosophical, in exploring the significance of the texts for the meaning of human existence in society and history. _Anamnesis_ is a pivotal work within Voegelin's intellectual odyssey. Alone among Voegelin's books, it reveals an author looking back and taking stock of his growth rather than customarily forging ahead into new regions and new problems. This critical work is both a recollection of Voegelin's own development, reaching back even to his infant memories, and a demonstration of the anamnetic method as applied to a wide range of historically remembered materials. Written as more than just a collection of essays, _Anamnesis_ is the volume in which Voegelin works out for himself the reconceptualization of what _Order and History,_ and by definition his central philosophical approach, is going to be. By revisiting his previous work—a departure from Voegelin's usual scholarly habits—he found at last the literary form for the kind of empirical philosophical meditation that had long absorbed his labors. Parts I and III contain biographical and meditative reflections written by Voegelin in 1943 and 1965, respectively. The first part details the breakthrough by which Voegelin recovered consciousness from the current theories of consciousness. Part III begins as a rethinking of the Aristotelian exegesis of consciousness, and then expands into new areas of awareness that had not come within the knowledge of classic philosophy. Between these two meditative selections are eight studies that demonstrate how the historical phenomena of order gave rise to the type of analysis which culminates in the meditative exploration of consciousness.

In this essay, David Waddington and Noah Weeth Feinstein explore how Dewey's conception of science can help us rethink the way science is done in schools. The authors begin by contrasting a view of science that is implicitly accepted by many scientists and science educators — science as a search for truth — with Dewey's instrumentalist, technological, and nonrealist conception of science. After demonstrating that the search-for-truth conception is closely linked to some ongoing difficulties with science curricula that students (...) find particularly alienating, they then analyze some of the educational opportunities that Dewey's vision opens up. Ultimately, Waddington and Weeth Feinstein argue that Dewey offers a humble and humanistic vision of science and science education practice that captures the power of science by connecting it clearly to everyday human activities and challenges.

It does so by way of an extended analogy with the funny. In part 1, it makes the easier and less controversial case for response-dependence about the funny. In part 2, it shows the tight analogy between anger and amusement in developing the harder and more controversial case for (...) response-dependence about a kind of blameworthiness. It then defends the view from three serious skeptical challenges. (shrink)

Gaston Bachelard's thought remains a continual source of inspiration for a phenomenological psychology that takes human habitation as a fundamental given and as an abiding mystery of the human condition. the following essay explores the ideas Bachelard developed in the course of his study of poetry.

Within that perspective, our lives are constantly renewed (...) by the appearance of a revealing image or a telling metaphor. Each time that we are awakened by this appeal we commemorate the birth and rebirth of a human world. (shrink)

This study examines Herbert Spencer's social and political thought by way of his principle of equal freedom. This principle reads, "The liberty of each, limited by the like liberty of each, is the rule in conformity with which society must be organized." ;Basically, this study attempts to demonstrate that Spencer was first and foremost an indirect utilitarian and that equal freedom was the central moral rule of his indirect utilitarianism. An attempt is also made to show how Spencer conceived moral (...) rights as derivations of equal freedom. For Spencer, moral rights were substantive specifications of equal freedom. Like their parent principle, they indirectly promoted happiness. Among other things, my analysis of equal freedom and rights endeavors to clarify how Spencer tried to accommodate a theory of stringent moral rights with utility and how negative freedom and virtue can be seen as compatible features of his theory of freedom. These two themes are meant to comprise some of the most promising rewards of this study. ;This study also explores Spencer's ethical naturalism via G. E. Moore's famous criticisms in Principia Ethica and via some of Henry Sidgwick's critical observations. While Moore's discussion is judged unsatisfactory, Sidgwick's analysis is deemed more successful. ;Finally, this study concludes by examining Spencer's theory of freedom and rights in terms of two fundamental moral rights and in terms of Spencer's vision of utopia.

Arguably the most influential of all contemporary English-speaking philosophers, Richard Rorty has transformed the way many inside and outside philosophy think about the discipline and the traditional ways of practising it. Drawing on a wide range of thinkers from Darwin and James to Quine, Wittgenstein, Heidegger and Derrida, Rorty has injected a bold anti-foundationalist vision into philosophical debate, into discussions in literary theory, communication studies, political theory and education, and, as public intellectual, into national debates about the (...) responsibilities of America in the modern world. The essays in this volume offer a balanced exposition and critique of Rorty's views on knowledge, language, truth, science, morality and politics. The editorial introduction presents a valuable overview of Rorty's philosophical vision. Written by a distinguished team of philosophers, this volume will have an unusual appeal outside philosophy to students in the social sciences, literary studies, cultural studies and political theory.

In recent years, Bayesian probability theory has emerged not only as a powerful tool for building computational theories of vision, but also as a general paradigm for studying human visual perception. This book provides an introduction to and critical analysis of the Bayesian paradigm. Leading researchers in computer vision and experimental vision science describe general theoretical frameworks for modeling vision, detailed applications to specific problems and implications for experimental studies of human perception. The book provides (...) a dialogue between different perspectives both within chapters, which draw on insights from experimental and computational work, and between chapters, through commentaries written by the contributors on each other's work. Students and researchers in cognitive and visual science will find much to interest them in this thought-provoking collection. (shrink)

Aristotle's claims that 'man is a political animal' and that political community 'exists for the sake of living well' have frequently been celebrated by thinkers of divergent political persuasions. The details of his political philosophy, however, have often been regarded as outmoded, contradictory, or pernicious. This book takes on the major problems that arise in attempting to understand how the central pieces of Aristotle's political thought fit together: can a conception of politics that seems fundamentally inclusive and egalitarian be reconciled (...) with a vision of justice that seems uncompromisingly hierarchical and authoritarian? Riesbeck argues that Aristotle's ideas about the distinctive nature and value of political community, political authority, and political participation are coherent and consistent with his aristocratic standards of justice. The result is a theory that, while not free of problems, remains a potentially fruitful resource for contemporary thinking about the persistent problems of political life. (shrink)

‘Methodological cosmopolitanism’ connotes a profound transformation of the sciences as forms of public reflexive social analysis on learning to live well together through building homes in the world: what may be called the ‘Beckian vision’, in memory of Ulrich Beck. This short note considers how Beck’s concept of emancipatory catastrophism may not be the most productive development of his own programme. This is precisely brought out by a methodologically cosmopolitan analysis of a key East Asian response to the global (...) risk of climate change: innovation of low-carbon cities in China. Instead, these presumptively archetypically cosmopolitan initiatives offer something of a political education regarding the irreducibly strategic power/knowledge dynamics at work – including in ongoing contestation about the very term ‘cosmopolitan’.

Civilizational analysis of the kind propounded by Eisenstadt and globalization theory are apparently wholly incommensurate paradigms, with radically differing visions of the contemporary world order, the former championing the notion of ‘multiple modernities’ and the latter envisioning a world of trans-national processes and institutions. This articles challenges such a dichotomizing view, and seeks to illustrate how in various ways they overlap and can come to inform each other. Particular attention is given to how a focus on inter-civilizational interactions can (...) lead to productive rapprochements between civilizational analysis and globalization theory, as it allows some of the themes of the latter to be analysed through civilization-analytic lenses. The pioneering work in this regard of Benjamin Nelson is shown to provide a basis for future civilizational analyses of globalization, especially in the pre-modern world. (shrink)

A great deal of philosophical work has addressed the question of whether Man’s computational theory of early vision is individualistic. Burge and Davies have argued that, according to Marr’s theory, visual states are individuated non-individualistically. Segal has denied that Marr’s theory has these non-individualistic implications. More recently, Shapiro has argued that the entire debate has been misguided. I argue that Shapiro is mistaken in a fairly deep way, attention to which allows us to raise and clarify (...) several important issues involved in discussions of individualism. Contrary to Burge and Davies, and by a route rather different from Segal’s, I defend the claim that Man’s theory offers no reason to think that visual states are individuated non-individualistically.

The vision of quantum physics developed by David Bohm, and especially the idea of the implicit order, can be considered the true epistemological foundation of quantum field theory and the idea of a quantum vacuum that underlies the observable forms of matter, energy and space-time. Assuming the non-locality as the crucial visiting card of quantum processes, it is thus possible to arrive directly to the transactional interpretation and to the idea of a non-local quantum vacuum in which (...) the behaviour of a subatomic particle constitutes the manifestation of more elementary creation/annihilation processes of quanta.

Much discourse on low-carbon transition envisages progressive social change towards environmentally sustainable and more equitable societies. Yet much of this literature pays inadequate attention to the key question of power. How do energy infrastructures and socio-technical systems interact with, construct, enable and constrain political regimes, and vice versa? Conceiving low-carbon energy transitions through a power lens, the paper explores a case study of huge, but overlooked, significance: the paradox of the ‘phenomenal’ resurgence of coal in an era of low-carbon innovation. (...) Through exposition of the strong connections between coal-based socio-technical systems and a political regime of classical liberalism, illustrated in two eras, we trace an emerging constellation of energy and political regimes connecting ‘clean coal’ with a ‘liberalism 2.0’ centred on a rising China. This affords a critique of the low-carbon society emergent from these developments – a society more reminiscent of coal's previous Dickensian heyday than the progressive visions of much ‘low-carbon transition’ literature.

This review of Matthew Lipman’s autobiography, A Life Teaching Thinking, is a reflection on the themes and patterns of his extraordinarily productive career. His book begins with memories of earliest childhood and his preoccupation with the possibility of being able to fly, moves through the years in which his family struggled with the effects of the Great Depression, through his service in the military during World War II, his discovery of the joy and beauty of philosophy, his academic rise at (...) Columbia University, his Fullbright sojourn in Paris, and his early and later career. Lipman’s educational project led in four related directions: the practice of philosophy for children, which he invented, and which presents an epistemological challenge to a second field, philosophy of education, which is as startling as was Rousseau’s two hundred years before. Third, it led to a realm of theory called philosophy of childhood, upon which the practice of philosophy for children is a kind of action-meditation, prompting adults as it does to reflect on children’s differences from and similarities to adults at the same time, and in the same discursive space. Finally, his praxis also implicitly challenged those accounts of children’s philosophies, paradigmatically represented by Piaget’s work, which represent childhood epistemology as evidence for various genetic and epigenetic stage-based theories of cognitive development. The consequence for education of this confluence was a methodology—community of inquiry—that serves as a bridge between the two most influential philosophers of education of the 20th century—John Dewey and Paulo Freire. The educational praxis that emerged from his venture, for all its apparent simplicity, operationalizes a postcolonial standpoint epistemology vis a vis childhood and children, pulls the linchpin that holds in place the school as ideological state apparatus, and empowers the elementary classroom as a primary site for democratic theory and practice.

Discussion about one of my papers on Berkeley.

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping (...) causal patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

This paper is an exploration of the Cartesian paradigms of clarity and univocity and how these inform contemporary educational theory and practice. Phenomenology is discussed as a way of disrupting Descartes' visions of clarity and distinctness as paradigms of knowledge and as a return of inquiry to life as it is actually lived. Analogical discourse is examined as a way of giving a voice to this sort of inquiry. Heidegger's notions of inquiry as obedience and thanksgiving are discussed.

This paper explores the plausibility of Alain Badiou's ahistorical theory of politics. By insisting that the events of egalitarian politics are radically subtracted from social and historical conditions Badiou imagines a form of political action that effectively comes out of nothing. However, in order to establish the very prospect of an event's occurrence Badiou is forced to ground the possibility of political intervention in his theory of "evental recurrence", which effectively enables the subjects of political action to draw (...) on the consequences of a preceding event in order to act in the here and now. The paper argues that by introducing the social dimensions of evental recurrence it is possible to construct an alternative account of political action that resolves a number of inconsistencies in Badiou's otherwise miraculous vision of politics. Consequently, rather than a militant activist that comes out of nowhere, evental recurrence implies that the militants of political action are saturated in their immediate social and political circumstances and in the memory of past struggles.

Intermediate‐level hypothesis (ILH) is the cornerstone of an adequate theory of consciousness. Ray Jackendoff's ILH is intended to apply to all sensory experience, including the experience of language. This chapter focuses on vision, because this is the most extensively studied sense. Jackendoff's views on vision were shaped by the seminal work of David Marr. Visual consciousness arises at an intermediate level, which occurs between discrete pixels and abstract models. The most compelling evidence for ILH comes from (...) studies of individuals with focal brain injuries. The findings from neuropsychology, electrophysiology, and functional imaging provide a strong case for ILH in vision. Jackendoff argues that ILH applies to all sense modalities. Research on the other senses lags woefully behind research on vision. On the strong version of Jackendoff's view, all consciousness resides at the intermediate level of perceptual systems. (shrink)

Many epistemologists hold that an agent can come to justifiably believe that p is true by seeing that it appears that p is true, without having any antecedent reason to believe that visual impressions are generally reliable. Certain reliabilists think this, at least if the agent’s vision is generally reliable. And it is a central tenet of dogmatism (as described by Pryor (2000) and Pryor (2004)) that this is possible. Against these positions it has been argued (e.g. by Cohen (...) (2005) and White (2006)) that this violates some principles from probabilistic learning theory. To see the problem, let’s note what the dogmatist thinks we can learn by paying attention to how things appear. (The reliabilist says the same things, but we’ll focus on the dogmatist.) Suppose an agent receives an appearance that p, and comes to believe that p. Letting Ap be the proposition that it appears to the agent that p, and → be the material implication, we can say that the agent learns that p, and hence is in a position to infer Ap → p, once they receive the evidence Ap.1 This is surprising, because we can prove the following.

By offering an apology of Japan's closed country policy, Engelbert Kaempfer (1651–1716) was contributing not so much to the literature of exotic journey record, but rather to the field of European political and moral theory, and importantly to the debate over the relative merits of ancient and modern societies and effects of international commerce. There is a marked lack of scholarly attention given to Kaempfer as a modestly interesting political theorist, compared to a substantial body of research praising his (...) record as a scientifically minded observer of remote cultures. As a deceptively straightforward specimen of the genre of travelogue, and also because it has tended to be treated mostly as a pioneering attempt in western Japanese studies, Kaempfer's work has not generally been considered in its relation to the debate on Europe's own moral and political predicament. When it has, the emphasis tended to be on the influence his work exercised on the enlightened European mind and its awareness of alien cultures, rather than on the extent to which the moral and political questions he sought to answer regarding Japan's situation were in fact standard questions formulated within the wider European debate on commerce and government. This paper hopes to correct the imbalance by placing Kaempfer's argument into the context of such contrasting contemporaneous positions as those represented, respectively, by Joseph Addison's view of global commerce in The Spectator and by François Fénelon's vision of the ideal commonwealth of Salente in his Aventures de Télemaque. ☆ The present article was written as part of the author's stay in 2008 at the Centre for History and Economics, King's College, Cambridge, made possible by Andrew W. Mellon Foundation research grant. The author would like to thank the staff of the Centre for an unfailing support, and to Istvan Hont and Carolina Armenteros for invaluable comments on the text.

This fundamental and straightforward text addresses a weakness observed among present-day students, namely a lack of familiarity with formal proof. Beginning with the idea of mathematical proof and the need for it, associated technical and logical skills are developed with care and then brought to bear on the core material of analysis in such a lucid presentation that the development reads naturally and in a straightforward progression. Retaining the core text, the second edition has additional worked examples which users have (...) indicated a need for, in addition to more emphasis on how analysis can be used to tell the accuracy of the approximations to the quantities of interest which arise in analytical limits.

ABSTRACT In 1992, John Dunn published an essay in Italian (which came out in English only years later) in which he summarized and clarified certain aspects of his historiographical vision concerning the history of political theory. A careful analysis of the text – corroborated by a consideration of later comments as well as general historical-theoretical references – gives us an insight into the lights and shadows of his thought. This reinterpretation reveals the originality of a perspective that examined (...) the meaning of ‘canon’ within the history of political theory, and indicated certain cultural and political aims to be consciously pursued through it. This original thought has recently been consolidated by other considerations on the need for a global history of political thought capable of offering interesting food for thought. Nevertheless, these seem to have emerged from a change of opinion on Dunn’s part, focusing to a greater extent on certain (more or less well-defined) moral duties that should be pursued by scholars of the history of political thought.
