This article attempts to demystify computer vision for novice programmers through a survey of new applications in the arts, system design considerations, and contemporary tools. It introduces the concept and gives a brief history of computer vision within interactive art from Myron Kruger to the present. Basic techniques of computer vision such as detecting motion and object tracking are discussed in addition to various software applications created for exploring the topic. As an example, the results of a one-week machine vision (...) workshop are presented to show how designers are able to apply their skills toward creating novel uses of these technologies. The article concludes with a listing of code for basic computer vision techniques. (shrink)

This is a unique study, contuining the work of Merleau-Ponty and Heidegger, and using the techniques of phenomenology against the prevailing nihilism of our culture. It expands our understanding of the human potential for spiritual self-realization by interpreting it as the developing of a bodily-felt awareness informing our gestures and movements. The author argues that a psychological focus on our experience of well-being and pathology as embodied beings contributes significantly to a historically relevant critique of ideology. It also provides an (...) essential touchstone in experience for a fruitful individual and collective response to the danger of nihilism. Dr Levin draws on Merleau-Ponty's phenomenology to clarify Heidegger's analytic of human beings through an interpretation that focuses on our experience of being embodied. He reconstructs in modern terms the wisdom implicit in western and semitic forms of religion and philosophy, considering the work of Freud, Jung, Focault and Neitzsche, as well as that of American educational philosophers, including Dewey. In particular, he draws on the psychology of Freud and Jung to clarify our historical experience of gesture and movement and to bring to light its potential in the fulfilment of Selfhood. Throughout the book, the pathologies of the ego and its journey into Selfhood are considered in relation to the conditons of technology and the powers of nihilism. (shrink)

Levin argues that the results of the most methodologically sound and philosophically relevant studies discussed in this volume [ Experimental Philosophy] could have been obtained from the armchair, and thus that experimental philosophy may not present a serious challenge to the traditional methods of analytic philosophy.

According to transhumanists who urge the radical enhancement of human beings, humanity’s top priority should be engineering “posthumans,” whose features would include agelessness. Increasingly, transhumanism is critiqued on foundational grounds rather than based largely on anticipated results of its implementation, such as rising social inequality. This expansion is crucial but insufficient because, despite its radical aim, transhumanism reflects beliefs and attitudes that are evident in the broader culture. With a focus on the yearning to eliminate aging, I consider four of (...) these: a disproportionate reliance on science and technology to address major human challenges; the conceptualization of human beings in terms of binaries like “young-old”; a repudiation of vulnerability; and intensifying perfectionism. Illuminating these interlocked commitments both deepens an existing critique of transhumanism and draws our attention to deleterious cultural views that must be vigorously contested if our commitment to human flourishing is to be deep and unwavering.

Reliabilism holds that knowledge is true belief reliably caused. Reliabilists should say something about individuating processes; critics deny that the right degree of generality can be specified without arbitrariness. It is argued that this criticism applies as well to processes mentioned in scientific explanations. The gratuitous puzzles created thereby show that the “generality problem” is illusory.

This collection of original essays by preeminent interpreters of continental philosophy explores the question of whether Western thought and culture have been dominated by a vision-centered paradigm of knowledge, ethics, and power. It focuses on the character of vision in modern philosophy and on arguments for and against the view that contemporary life and thought are distinctively "ocularcentric." The authors examine these ideas in the context of the history of philosophy and consider the character of visual discourse in the writings (...) of Plato, Descartes, Hegel, Nietzsche, Husserl, Heidegger, Benjamin, Sartre, Merleau-Ponty, Levinas, Derrida, Foucault, Gadamer, Wittgenstein, and Habermas. With essays on television, the visual arts, and feminism, the book will interest readers in cultural studies, gender studies, and art history as well as philosophers. (shrink)

Philosophers have traditionally held that claims about necessities and possibilities are to be evaluated by consulting our philosophical intuitions; that is, those peculiarly compelling deliverances about possibilities that arise from a serious and reflective attempt to conceive of counterexamples to these claims. But many contemporary philosophers, particularly naturalists, argue that intuitions of this sort are unreliable, citing examples of once-intuitive, but now abandoned, philosophical theses, as well as recent psychological studies that seem to establish the general fallibility of intuition.In the (...) first two sections of this paper, I evaluate these arguments, and also the counter-arguments of contemporary defenders of tradition. In the next two sections, I sketch an alternative account of the role of philosophical intuitions that incorporates elements of traditionalism and naturalism - and defend it against other such views. In the final section, however, I discuss intuitions about conscious experience, and acknowledge that my view may not extend comfortably to this case. This may seem unfortunate, since so much contemporary discussion of the epistemology of modality seems motivated by worries about the mind-body problem, and informed by the position one wishes to endorse. But, as I argue, if conscious experience is indeed an exception to the view I suggest in this paper, it is an exception that proves - and can illuminate - the rule. (shrink)

In this paper I discuss the claim that the successful reduction of qualitative to physical states requires some sort of intelligible connection between our qualitative and physical concepts, which in turn requires a conceptual analysis of our qualitative concepts in causal-functional terms. While I defend this claim against some of its recent critics, I ultimately dispute it, and propose a different way to get the requisite intelligible connection between qualitative and physical concepts.

David Michael Levin's ongoing exploration of the moral character and enlightenment-potential of vision takes a new direction in _The Philosopher's Gaze_. Levin examines texts by Descartes, Husserl, Wittgenstein, Nietzsche, Heidegger, Benjamin, Merleau-Ponty, and Lévinas, using our culturally dominant mode of perception and the philosophical discourse it has generated as the site for his critical reflections on the moral culture in which we are living. In Levin's view, all these philosophers attempted to understand, one way or another, the (...) distinctive pathologies of the modern age. But every one also attempted to envision—if only through the faintest of traces, traces of mutual recognition, traces of another way of looking and seeing—the prospects for a radically different lifeworld. The world, after all, inevitably reflects back to us the character, the reach and range, of our vision. In these provocative essays, the author draws on the language of hermeneutical phenomenology and at the same time refines phenomenology itself as a method of working with our experience and thinking critically about the culture in which we live.

Defends the ancient thesis that man is a piece of matter, that all his states are physical states, and all his properties physical properties. This is done in a metaphysical framework which accommodates talk of the identity and diversity of such 'virtual entites' as states and properties without being committed to their actual existence.

Evolution exploits the physics of non‐neural bioelectricity to implement anatomical homeostasis: a process in which embryonic patterning, remodeling, and regeneration achieve invariant anatomical outcomes despite external interventions. Linear “developmental pathways” are often inadequate explanations for dynamic large‐scale pattern regulation, even when they accurately capture relationships between molecular components. Biophysical and computational aspects of collective cell activity toward a target morphology reveal interesting aspects of causation in biology. This is critical not only for unraveling evolutionary and developmental events, but also for (...) the design of effective strategies for biomedical intervention. Bioelectrical controls of growth and form, including stochastic behavior in such circuits, highlight the need for the formulation of nuanced views of pathways, drivers of system‐level outcomes, and modularity, borrowing from concepts in related disciplines such as cybernetics, control theory, computational neuroscience, and information theory. This approach has numerous practical implications for basic research and for applications in regenerative medicine and synthetic bioengineering. (shrink)

From the standpoint of disability advocacy, further exploration of the concept of well-being stands to be availing. The notion that “welfarism” about disability, which Julian Savulescu and Guy Kahane debuted, qualifies as helpful is encouraged by their claim that welfarism shares important commitments with that advocacy. As becomes clear when they apply their welfarist frame to procreative decisions, endorsing welfarism would, in fact, sharply undermine it. Savulescu and Kahane's Principle of Procreative Beneficence—which reflects transhumanism, or advocacy of radical bioenhancement—morally requires (...) parents to choose the child who will, in all probability, have “the best life.” Assuming the emergence of potent biotechnologies, procreative decision-making would be highly standardized, for prospective parents would be morally obliged to maximize select capacities, including intelligence, self-control, and hedonic set-point, in their children. Welfarism, applied to reproduction, is staunchly objectivist about what course is incumbent on decision-makers, giving no credence to first-personal values, aspirations, and experiences. Though this dismissal of individual perspectives applies to everyone, its implications for disability advocacy are especially severe. With that advocacy in view, greater attention to “well-being” should, therefore, be severed from the welfarism of Savulescu and Kahane. (shrink)

In a footnote to his ‘What is it Like to be a Bat?’, Thomas Nagel sketches a promising account of phenomenal concepts that purports to explain why mind-body identity statements, even if necessary, will always seem contingent. Christopher Hill and Brian McLaughlin have recently developed this sketch into a more robust theory. In Nagel's more recent work, however, he suggests that the only adequate theory of phenomenal concepts is one that makes the relation between phenomenal and physical states intelligible, or (...) ‘transparent’. Developing such a theory, however, appears to be no easy task. In this paper I argue that the Nagel-Hill-McLaughlin proposal is preferable – and that a serious problem with it, noticed by Stephen Yablo, can be avoided by revising the proposal according to some further suggestions made by Nagel himself.

To reassure those concerned about wholesale discontinuity between human existence and posthumanity, transhumanists assert shared ground with antiquity on vital challenges and aspirations. Because their claims reflect key misconceptions, there is no shared vision for transhumanists to invoke. Having exposed their misuses of Prometheus, Plato, and Aristotle, I show that not only do transhumanists and antiquity crucially diverge on our relation to ideals, contrast-dependent aspiration, and worthy endeavors but that illumining this divide exposes central weaknesses in transhumanist argumentation. What is (...) more, antiquity’s handling of these topics suggests a way through the impasse in current enhancement debates about human “nature” and helps to resolve a tension within transhumanists’ accounts of what our best moments signify about the ontological requirements for real flourishing.

In this thoughtful, rich, and extremely ambitious book, Norton Nelkin develops a "Scientific Cartesian" theory of sensation and perception, consciousness, conceptual content, and concept formation. The theory is Cartesian primarily because its account of mental states is realist, individualist, and internalist; Nelkin also holds, with Descartes, that perceptions are spontaneous judgments and that at least some of our concepts are innate. But, unlike Descartes, Nelkin rejects dualism and treats the mind as something that can be studied by the same methods (...) as other natural phenomena; indeed, Nelkin goes further than many contemporary theorists in attempting to make his views consistent with, and informed by, studies in the cognitive sciences.

Our studies of naturally occurring human dialogue have led to the recognition of a class of regularities which characterize impoltant aspects of communication. People appear to interact according to established patterns which span several turns in a dialogue and which recur frequently. These patterns appear to be organized around the goals which the dialogue serves for each participant. Many things which are said later in a dialogue can only be interpreted as pursuit of these goals, established by earlier dialogue.These patterns (...) have been represented b) a set of knowledge structures called Dialogue‐Games, capturing shared, conventional knowledge that people have about communication and how it can be used to achieve goals. A Dialogue‐Game has Parameters, which represent those elements that vary across instances of a particular pattern‐the particular dialogue participants and the content topic. The states of the world which must be in effect for a particular Dialogue‐Game to be employed successfully are represented by Specifications of these Parameters. Finally, the expected sequence of intermediate states that occur during instances of a particular conventional pattern are represented by the Components of the corresponding Dialogue‐Game.Representations for several Dialogue‐Games are presented here, based on our analyses of different kinds of naturally occurring dialogue. A process model is discussed, showing Dialogue‐Game identification, pursuit, and termination as part of the comprehension of dialogue utterances. This Dialogue‐Game model captures some of the important functional aspects of language, especially indirect uses to achieve implicit communication. (shrink)

This paper examines the adequacy of an evolutionary-oriented notion of rationality—ecological rationality—that has recently been proposed in economics. Ecological rationality is concerned with what it is rational to do, and in this sense is a version of what philosophers call ‘practical rationality’. Indeed, the question of the adequacy of ecological rationality as it is understood in the paper, is the question of whether ecological rationality is a genuine notion of practical rationality. The paper first explicates and motivates the notion of (...) ecological rationality by (a) explicating the notion of practical rationality, (b) grounding ecological rationality in an evolutionary approach to the emotions which is mainly illustrated by the example of fear, and (c) outlining the reasons adduced in economics for generalizing ecological rationality beyond the emotions. The paper then argues that (d) the raison d’être of practical rationality is first and foremost a specific role it plays in the explanation of behavior, or in telling why it has occurred. Finally, based on (a)–(d), the paper argues that (e) ecological rationality lacks a constitutive feature of practical rationality—namely, normativity—which is related to the latter’s basic explanatory role, and thus cannot be considered a genuine notion of practical rationality. While the paper focuses on the economic version of ecological rationality, its conclusions apply just as well to other, related, versions of the ecological notion that have been proposed in biology and evolutionary psychology.

This paper challenges some leading views about the conditions under which the ascription of beliefs and desires can make sense of, or provide reasons for, a creature's behavior. I argue that it is unnecessary for behavior to proceed from beliefs and desires according to the principles of logic and decision theory, or even from principles that generally get things right. I also deny that it is necessary for behavior to proceed from principles that, though perhaps subrational, are similar to those (...) that we ourselves use. I then propose some conditions that are considerably weaker, and argue that they fulfill the descriptive and explanatory requirements of intentional ascription. (shrink)

The principal argument of the present paper is that the human body is as much a reflective formation of multiple discourses as it is an effect of natural and environmental processes. This paper examines the implications of this argument, and suggests that recognizing the body in this light can be illuminating, not only for our conception of the body, but also for our understanding of medicine. Since medicine is itself a discursive formation, a science with both a history, and a (...) future, it is argued that much can be learned by reflecting on the progression of models, or “paradigm-shifts,”, in terms of which modern medicine has articulated the human body that figures at the heart of its discourse. Four historical periods of medicine will be considered, each one governed by its own distinctive paradigm. It is argued, finally, that, with the emergence of behavioural medicine, and, more particularly, psychoneuroimmunology, a new discursive formation in medicine, one can see a new conceptualization of the human body beginning to take shape; and that this new figure of the body makes it possible for the very first time to conceive the construction of testable hypotheses regarding correlations between the objective body of science and the phenomenological body of experienced meaning.

A recent study published in Nature Neuroscience purports to have answered a question posed to Locke in 1688 by his friend William Molyneux, namely, whether ‘a man born blind and made to see’ would be able to identify, immediately and by vision alone, objects previously known only by touch. The answer, according to the researchers – and as predicted by Molyneux, as well as Locke, Berkeley, and others – is ‘likely negative. The newly sighted subjects did not exhibit an immediate (...) transfer of their tactile shape knowledge to the visual domain’. Since then, however, many commentators have argued that the answer is still not clear. Moreover, in the contemporary literature on Molyneux’s Question, and more generally on cross-modal perception and the individuation of the senses, it is sometimes hard to determine what question is being investigated. In this paper, I distinguish a number of different questions about the relation between visual and tactual perception that can arise when considering Molyneux’s... (shrink)

Birch, Ginsburg, and Jablonka lay out a very convincing case for an important transition marker: unlimited associative learning. Especially welcome are the empirical predictions. I focus here not on the question of how to infer phenomenal consciousness from this behavioral metric, but on possible novel applications of this useful and fundamental framework. Specifically, I highlight two aspects of biology that are often not considered in philosophy of mind approaches that focus on natural species and evolutionary time scales. These are the (...) ability of minds and bodies to change drastically on the time scale of an individual experiencing subject, and bioengineering of novel living forms with no evolutionary history at the organism level. Both of these aspects provide interesting new contexts within which to explore UAL and its implications. (shrink)

Perhaps there is nothing morally wrong with homosexuality. But does that mean that those who find it abhorrent should be forced to tolerate, it? Michael Levin questions some common liberal preconceptions about homosexuality, and also responds to my own (which appeared in Issue 5 of Think).

In lieu of an abstract, here is a brief excerpt of the content:David Michael Levin ROUSSEAU'S CURSE Pretext Rousseau is the author of a text he called his Confessions. ' But neither a text nor a confession can exist without a reader, or an other. Like it or not, we readers are participants in the rite of Rousseau's confessions. Do we have anything to confess? When the reading of a confession uncovers the spelling of a curse, so that the (...) self-accused author appears to accuse his readers, the discoverers of the curse can no longer pretend their neutrality and innocence. In fact, the detectives must assume the identity of the accused. In such a special case, then, the inevitable work of textual interpretation magically doubles as the story of a mysteriously elusive "crime" and its final, or anyway presumed detection. But, as in the very best of such stories, neither the skillfully executed crime nor its invisible author—if indeed these terms denote anything at all—need be what they seem. So perhaps the only thing we can say for sure here is that the spelling of the curse is the curse of spelling. And this puts us on the track of a mystery as ancient as the art of writing itself—a mystery whose story the scholars of hermeneutics have thus far preferred to ignore. The mystery I have in mind is the secret affinity between writing and death. A careful hermeneutic approach to Plato's critique of writing, however, may give us a crucial clue. For what binds written language to the power of death is its role in mourning, its incarnation in the form of shadows: black configurations of shadows placed for visibility against the white of the paper. In Plato's Myth of the Cave, the crime of writing is dimly adumbrated. Writing is idolatry, worship of false images, shadows. Rousseau's Confessions, written near the end of his life in the shadow of death, does not escape the shadows of doubt and suspicion which we, his readers, having discovered our own selves inscribed into the darkness of the text, cannot easily refrain from casting. But as soon as we recognize in the shapes of these shadows a suspicion for which 76 David Michael Levin77 we are responsible, we must confess our fatal complicity in the closing of the hermeneutical circle. Commentary on the Text If Rousseau's Confessions does not read like the typical memoir, neither does it read like the typical confession. A final twist awaits us. We read with a certain innocence, or faith, not prepared for the transitive conclusion: the text, as it happens, will bequeath a monstrous and impossible burden. What is the reader to do? How could it be that this man, who seemed to honor us, and won our trust with the candor of his revelations, should so boldly, by one cross conceit, vanish, only to leave us double-crossed and within a labyrinth which, as he would have us believe, we ourselves have wrought? What are we to make of his work? At first, the Confessions appears to be a work of light: with dazzling clarity of mind and courage no less prismatic, Rousseau proposes to take his readers into the gloomy chasms of his soul. "My purpose," he declares, "is to display to my kind a portrait in every way true to nature, and the man I shall portray is myself" (p. 17). That this, however, is not the whole of his intention, we learn through a neighboring sentence. For he says: "Let the last trumpet sound when it will, I shall come forward with this work in my hand, to present myself before my Sovereign Judge, and proclaim aloud: 'Here is what I have done'..." (p. 17). And yet, even this does not fully disclose his design, since he concedes, somewhat later, that "it is as if, feeling my life escaping from me, I were trying to recapture it at its beginnings" (p. 31). But in the end, as in the beginning, darkness and light are one. And indeed, deep into the Seventh Book, we see that the author's light does begin to dim, and that he no longer speaks with much assurance. Nor is... (shrink)

In Spinoza’s substance monism, radically different attributes constitute the essence of one and the same substance qua a strongly unified whole. Showing how this is possible poses a formidable Cartesian challenge to Spinoza’s metaphysics. In this paper I suggest a reconstruction of Spinoza’s notion of substance that meets this challenge and explains a major feature of this notion. I then show how this reconstruction can be used to resolve two fundamental problems of the Cartesian framework that pertain to Spinoza’s metaphysics. (...) On this basis, I then explain two further major features of Spinoza’s notion of substance. While my suggested reconstruction has all these advantages and accords well with Spinoza’s conceptual framework, it goes beyond what he explicitly says concerning substance monism. It is in the spirit of his metaphysical framework rather than in its letter. Thus, all I intend to show is that Spinoza has the conceptual resources for coming to terms with some of the deep problems that beset his metaphysics. (shrink)
