David Milner and Melvyn Goodale’s dissociation hypothesis is commonly taken to state that there are two functionally specialized cortical streams of visual processing originating in striate (V1) cortex: a dorsal, action-related “unconscious” stream and a ventral, perception-related “conscious” stream. As Milner and Goodale acknowledge, findings from blindsight studies suggest a more sophisticated picture that replaces the distinction between unconscious vision for action and conscious vision for perception with a tripartite division between unconscious vision for (...) class='Hi'>action, conscious vision for perception, and unconscious vision for perception. The combination excluded by the tripartite division is the possibility of conscious vision for action. But are there good grounds for concluding that there is no conscious vision for action? There is now overwhelming evidence that illusions and perceived size can have a significant effect on action (Bruno & Franz, 2009; Dassonville & Bala, 2004; Franz & Gegenfurtner, 2008; McIntosh & Lashley, 2008). There is also suggestive evidence that any sophisticated visual behavior requires collaboration between the two visual streams at every stage of the process (Schenk & McIntosh, 2010). I nonetheless want to make a case for the tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. My aim here is not to refute the evidence showing that conscious vision can affect action but rather to argue (a) that we cannot gain cognitive access to action-guiding dorsal stream representations, and (b) that these representations do not correlate with phenomenal consciousness. This vindicates the semi-conservative view that the dissociation hypothesis is best understood as a tripartite division. (shrink)

This paper examines Milner and Goodale’s hypothesis about the two visual streams and raises the questions of whether properties in egocentric space (commonly associated with the vision-for-action, or "dorsal," stream) can be part of the phenomenal content of perceptual experience, or only properties in allocentric space (commonly associated with the vision-for-perception, or "ventral," stream) can play this role, and how (if at all) properties in egocentric space differ from properties in allocentric space. These questions are reminiscent of (...) issues raised by Christopher Peacocke's "equal-sized trees" case: if you are looking at equal-sized trees on the side of a road, the trees will phenomenally look to you to be equally tall. But it is also true that a tree will take up more of the space in your visual field the closer it is to you. So, the equal-sized trees will also phenomenally look to you to have different heights. Your (visual) perceptual experience is not illusory. That is, the trees veridically look to you to have the same height, and they also veridically look to you to have different heights. Call the sort of issue raised here the "problem of dual looks." I provide a solution to the problem of dual looks that helps shed light on whether properties in egocentric space can be part of the phenomenal content of perceptual experience, and how (if at all) properties in egocentric space differ from properties in allocentric space.

Empirical work and philosophical analysis have led to widespread acceptance that vision for action, served by the cortical dorsal stream, is unconscious. I argue that the empirical argument for this claim is unsound. That argument relies on subjects’ introspective reports. Yet on biological grounds, in light of the theory of primate cortical vision, introspection has no access to dorsal stream mediated visual states. It is thus wrongly assumed that introspective reports speak to absent phenomenology in the dorsal (...) stream. In light of this, I consider a different conception of consciousness’s relation to agency in terms of access. While theoretical reasons suggest that the inaccessibility of the dorsal stream to conceptual report is evidence that it is unconscious, this position begs important questions. I propose a broader notion of access in respect of the guidance of intentional agency and not, narrowly, conceptual report (Note: this paper contradicts my earlier paper, "The Case for Zombie Agency").

According to an influential view, the detection of action possibilities and the selection of a plan for action are two segregated steps throughout the processing of visual information. This classical approach is committed with the assumption that two independent types of processing underlie visual perception: the semantic one, which is at the service of the identification of visually presented objects, and the pragmatic one which serves the execution of actions directed to specific parts of the same objects. However, (...) as our knowledge of vision has improved over the years, this established view has turned out to be only an approximation. This paper sets out the details of a non-modularist approach to visual perception of action possibilities and explains how to resist the lure of cognitive segregation. (shrink)

In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience suggests that these two functions are performed by two separate brain neural systems - the ventral and dorsal pathways. Two experiments using behavioural measures were conducted with the objective of exploring any potential interaction between these two functions of vision. The aim was to combine in one (...) task methods allowing for the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they infi uence each other. This aim was achieved by employing the paradigms of Navon and Tucker and Ellis. A compound fi gure was created made up of objects with handles that might or might not have orientation congruent between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action tend to act as separate systems. (shrink)

It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing (...) objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

As early-career neuroethicists, we come to the field of neuroethics at a unique moment: we are well-situated to consider nearly two decades of neuroethics scholarship and identify challenges that have persisted across time. But we are also looking squarely ahead, embarking on the next generation of exciting and productive neuroethics scholarship. In this article, we both reflect backwards and turn our gaze forward. First, we highlight criticisms of neuroethics, both from scholars within the field and outside it, that have focused (...) on speculation and lack of skepticism; the dearth of consideration of broader social issues such as justice and equality, both with regard to who speaks for neuroethics as a field and who benefits from its recommendations and findings; and the insufficient focus on the practical impact of our ethical work. Second, we embrace the concept of “translational neuroethics” to outline a vision for neuroethics that is integrated, inclusive, and impactful. Integration can help us identify more pertinent, real-world issues, and move away from speculation; inclusivity can help ensure that the questions we attend to are not merely relevant to a single subgroup but aim toward just distribution of benefits; and impact can help us think beyond guidelines and recommendations to focus on implementation. Our goal is for this call to action to help shape neuroethics into a discipline that develops rigorous research agendas through relationships with interdisciplinary partners, that is broadly inclusive and attends to issues beyond novel neurotechnologies, and that is devoted to the translation of scholarship into practice.

_A proactive, inclusive plan for the cross-disciplinary teaching of climate change from preschool to high school._ In _Teach for Climate Justice_, accomplished educator and social and emotional learning expert Tom Roderick proposes a visionary interdisciplinary and intersectional approach to PreK–12 climate education. He argues that meaningful instruction on this urgent issue of our time must focus on climate justice—the convergence of climate change and social justice—in a way that is emotionally safe, developmentally appropriate, and ultimately empowering. Drawing on examples of (...) real-life educators teaching climate change, Roderick identifies eight key dimensions of climate education that will prepare students to face the challenges of the climate crisis and give them the means to take action. These dimensions include not only educating for a deep understanding of the scientific, geopolitical, and socioeconomic equity issues that surround global warming, but also cultivating appreciation for the environment, building a supportive community, and fostering active hope for the future. Roderick's intentional layering of skills will help students develop the knowledge and sense of agency necessary to engage in civil resistance and nonviolent activism. In support of this crucial endeavor, Roderick suggests evidence-based teaching strategies, practices that promote inclusivity, and tools for social and emotional learning. This timely and uplifting book lays out a powerful vision for teaching, learning, and curriculum development to nurture a generation of courageous, informed advocates for climate justice. (shrink)

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid movements or (...) saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

According to Milner and Goodale’s dual visual systems (DVS) theory, a division obtains between visual consciousness and motor action, in that the visual system producing conscious vision (the ventral stream) is distinct from the one guiding action (the dorsal stream). That there would be this division is often taken (by Andy Clark and others) to undermine the folk view on how consciousness and action relate. However, even if this division obtains, this leaves open the possibility that (...) con- scious ventral information is often transmitted to the uncon- scious dorsal stream and then used to guide action, a possibility seeming to preserve a significant role for consciousness in action. This article assesses this possibility. In course of doing so, we will review those arguments recently having been made against the DVS view on how visual consciousness and action relate (ones due to, e.g., Briscoe and Schwenkler, or Schenk and McIntosh). What we will find is that, if we properly analyze the data upon which these arguments are based, we are still left with the impression that the DVS view is largely correct; i.e., it is only rarely that visual experience guides action.

In this book Gerald Vision argues for a new causal theory, one that engages provocatively with direct realism and makes no use of a now discredited subjectivism.

In Veritas, Gerald Vision defends the correspondence theory of truth -- the theory that truth has a direct relationship to reality -- against recent attacks, and critically examines its most influential alternatives. The correspondence theory, if successful, explains one way in which we are cognitively connected to the world; thus, it is claimed, truth -- while relevant to semantics, epistemology, and other studies -- also has significant metaphysical consequences. Although the correspondence theory is widely held today, Vision points (...) to an emerging orthodoxy in philosophy that claims that truth as such carries no significant weight in philosophical explanations. He devotes much of the book to a criticism of that outlook and to a less vulnerable formulation of the correspondence theory.Vision defends the correspondence theory by both presenting evidence for correspondence and examining the claims made by such alternative theories as deflationism, minimalism, and pluralism. The techniques of the argument are thoroughly analytic, but the problem confronted is broadly humanistic. The question examined -- how we, as thinking beings, are connected to and manage to cope in a world that was not designed for our comfort or convenience -- is more likely to be raised by continentalists, but is approached here with the tools of clarity and precision more highly prized in analytic philosophy. The book seeks to avoid both the obscurantism that infects much continental thought and the overly technical concerns and methodology that limit the interest of much work in analytic philosophy. It thus provides a rigorous but largely nontechnical treatment of the topic that will be of interest not only to readers familiar with philosophy but also to those with a background in literary theory and linguistics.

Discusses contemporary Confucianism's relevance and its capacity to address pressing social and political issues of twenty-first-century life. Condemned during the Maoist era as a relic of feudalism, Confucianism enjoyed a robust revival in post-Mao China as China’s economy began its rapid expansion and gradual integration into the global economy. Associated with economic development, individual growth, and social progress by its advocates, Confucianism became a potent force in shaping politics and society in mainland China, Hong Kong, Taiwan, and overseas Chinese communities. (...) This book links the contemporary Confucian revival to debates—both within and outside China—about global capitalism, East Asian modernity, political reforms, civil society, and human alienation. The contributors offer fresh insights on the contemporary Confucian revival as a broad cultural phenomenon, encompassing an interpretation of Confucian moral teaching; a theory of political action; a vision of social justice; and a perspective for a new global order, in addition to demonstrating that Confucianism is capable of addressing a wide range of social and political issues in the twenty-first century.

In specifying the sensory evidence for perceptual belief, thinkers have either chosen a common perceptual idiom or have invented one of their own as a starting-point for their enquiries. It is becoming clearer that the choice harbours crucial, often disputable, assumptions. I compare two sorts of constructions, a variety of propositional ones and an objectual one, and I argue that the objectual idiom is indispensable in order to explain how a perceptual belief can arise out of what is not already (...) a belief. This has implications not only for the question of how belief is generated from perceptual evidence, but also for various other controversies. I discuss two of these implications: the character of inferences from evidence, and basic belief. (shrink)

In _Action in Perception _Alva No develops and presents a sensorimotor account of vision and of visual consciousness. According to such an account seeing (and indeed perceiving more generally) is analysed as a kind of skilful bodily activity. Such a view is consistent with the emerging emphasis, in both philosophy and cognitive science, on the critical role of embodiment in the construction of intelligent agency. I shall argue, however, that the full sensorimotor model faces three important challenges. The first (...) is to negotiate a path between two prima facie unsatisfactory readings of the central claim that conscious perceptual experience is constituted by knowledge of patterns of sensorimotor dependence. The second is to convince us that the sensorimotor contribution, in such cases, is actually constitutive of perceptual experience rather than merely causally implicated in the origination of such experience.² And the third is to respond to the important challenge raised by what I will dub 'sensorimotor summarizing' models of the relation between conscious experience and richly detailed sensorimotor routines. According to such models³ conscious perceptual experience only rather indirectly reflects the rich detail of our actual sensorimotor engagements, which are instead lightly sampled as a coarse guide, optimized for planning and reasoning, and geared and filtered according to current needs and purposes.

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)

From the popular view that the property of truth adds nothing not already inherent in its bearers it has been inferred that classical theories of truth are thereby refuted. Taking as representative a version of deflationism based on a certain way of interpreting the Tarskian schema convention T–and popularly called "disquotational"–I argue that the view is beset by fatal difficulties. These include: an unavoidable awkwardness in handling indexicals; an inability to accept anything more than a too anemic notion of a (...) truth condition, leaving it defenseless against clearly inadequate alternatives; and an incapacity to show that its characteristic biconditional can support any acceptable dependency claims (made evident by replacing the biconditional with 'because'). Finally, were there no predicate on the order of 'is true', this would not annihilate the property of being true or the current grounds for philosophical inquiries about it. This is an important clue to why deflationary approaches in general are dead ends. (shrink)

Whereas it appears that direct, or causal, theories dominate philosophy’s theories of reference, and it is widely held that they present an insuperable obstacle for a fictional character’s name to refer, I attempt to show not only that they can be easily made compatible with such theories, but that reference to the fictional fits rather smoothly into the distinctive articles of current theories of direct reference. However, the issues about reference to fictional characters goes well beyond those points, so its (...) compatibility with direct referential theories is not a demonstration that names of fictional things in fact refer.

Moreover, if those references were to occur, it would remove a serious self-inflicted conundrum over negative existentials, one from which those raising it seem unable to extract themselves credibly.

On the assumption that phenomenal consciousness is real, and ruling out Cartesian isolation from the non-mental world, we have two choices for its introduction: either it comes about in the course of the development of the non-conscious realm or it was there from the beginning.

In their view the former are broadly taken to be versions of emergentism, embracing even non-eliminatiivist materialisms. After producing what seem to me (...) to be powerful objections to panpsychism, I defend emergentism against pansychist attacks on it. As I explain, my version is also dualist.

Standard physicalism is repudiated by Susan Schneider on the grounds that the science of physics at physicalism's foundation is individuated by mathematics, revealing that science is abstract rather than concrete. She seeks to remedy the situation for physics, though not for physicalism, with a panprotopsychist variant of panpyschism. Her approach is clever and well-developed, but I believe it suffers from at least two flaws. First, with few exceptions individuation is the wrong tool for the discovery of a thing's nature; second, (...) panpsychism and its proto variant have problems no less worrisome than those attributed to standard physicalism.

A social scientific survey on visions of human/nature relationships in western Europe shows that the public clearly distinguishes not only between anthropocentrism and ecocentrism, but also between two nonanthropocentric types of thought, which may be called “partnership with nature” and “participation in nature.” In addition, the respondents distinguish a form of human/nature relationship that is allied to traditional stewardship but has a more ecocentric content, labeled here as “guardianship of nature.” Further analysis shows that the general public does not subscribe (...) to an ethic of “mastery over nature.” Instead, practically all respondents embrace the image of guardianship, while the more radical relationships of partnership and participation also received significant levels of adherence. The results imply that ethicists should no longer assume that the ethics of the public are merely anthropocentric.

(1) The purported evidence for neural filling-in is not evidence for filling-in, but just for long-range dynamic interactions. (2) Vision is perhaps not an “illusion,” but at any rate it is not “pictorial.” (3) The idea of the “world as an outside memory” as well as MacKay's “conditional readiness for action” may help approach an “enactive” theory of vision.

Bowers et al. focus their criticisms on research that compares behavioral and brain data from the ventral stream with a class of deep neural networks for object recognition. While they are right to identify issues with current benchmarking research programs, they overlook a much more fundamental limitation of this literature: Disregarding the importance of action and interaction for perception.

Action is a means of acquiring perceptual information about the environment. Turning around, for example, alters your spatial relations to surrounding objects and, hence, which of their properties you visually perceive. Moving your hand over an object’s surface enables you to feel its shape, temperature, and texture. Sniffing and walking around a room enables you to track down the source of an unpleasant smell. Active or passive movements of the body can also generate useful sources of perceptual information (Gibson (...) 1966, 1979). The pattern of optic flow in the retinal image produced by forward locomotion, for example, contains information about the direction in which you are heading, while motion parallax is a “cue” used by the visual system to estimate the relative distances of objects in your field of view. In these uncontroversial ways and others, perception is instrumentally dependent on action. According to an explanatory framework that Susan Hurley (1998) dubs the “Input-Output Picture”, the dependence of perception on action is purely instrumental: "Movement can alter sensory inputs and so result in different perceptions… changes in output are merely a means to changes in input, on which perception depends directly" (1998: 342). -/- The action-based theories of perception, reviewed in this entry, challenge the Input-Output Picture. They maintain that perception can also depend in a noninstrumental or constitutive way on action (or, more generally, on capacities for object-directed motor control). This position has taken many different forms in the history of philosophy and psychology. Most action-based theories of perception in the last 300 years, however, have looked to action in order to explain how vision, in particular, acquires either all or some of its spatial representational content. Accordingly, these are the theories on which we shall focus here. -/- We begin in Section 1 by discussing George Berkeley’s Towards a New Theory of Vision (1709), the historical locus classicus of action-based theories of perception, and one of the most influential texts on vision ever written. Berkeley argues that the basic or “proper” deliverance of vision is not an arrangement of voluminous objects in three-dimensional space, but rather a two-dimensional manifold of light and color. We then turn to a discussion of Lotze, Helmholtz, and the local sign doctrine. The “local signs” were felt cues for the mind to know what sort of spatial content to imbue visual experience with. For Lotze, these cues were “inflowing” kinaesthetic feelings that result from actually moving the eyes, while, for Helmholtz, they were “outflowing” motor commands sent to move the eyes. -/- In Section 2, we discuss sensorimotor contingency theories, which became prominent in the 20thcentury. These views maintain that an ability to predict the sensory consequences of self-initiated actions is necessary for perception. Among the motivations for this family of theories is the problem of visual direction constancy—why do objects appear to be stationary even though the locations on the retina to which they reflect light change with every eye movement?—as well as experiments on adaptation to optical rearrangement devices (ORDs) and sensory substitution. -/- Section 3 examines two other important 20th century theories. According to what we shall call the motor component theory, efference copies generated in the oculomotor system and/or proprioceptive feedback from eye-movements are used together with incoming sensory inputs to determine the spatial attributes of perceived objects. Efferent readiness theories, by contrast, look to the particular ways in which perceptual states prepare the observer to move and act in relation to the environment. The modest readiness theory, as we shall call it, claims that the way an object’s spatial attributes are represented in visual experience can be modulated by one or another form of covert action planning. The bold readiness theory argues for the stronger claim that perception just is covert readiness for action. -/- In Section 4, we move to the disposition theory, most influentially articulated by Gareth Evans (1982, 1985), but more recently defended by Rick Grush (2000, 2007). Evans’ theory is, at its core, very similar to the bold efferent readiness theory. There are some notable differences, though. Evans’ account is more finely articulated in some philosophical respects. It also does not posit a reduction of perception to behavioral dispositions, but rather posits that certain complicated relations between perceptual input and behavioral provide spatial content. Grush proposes a very specific theory that is like Evans’ in that it does not posit a reduction, but unlike Evans’ view, does not put behavioral dispositions and sensory input on an undifferentiated footing.

They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

What representational state mediates between perception and action? Bence Nanay says pragmatic representations, which are outputs of perceptual systems. This commits him to the view that optic ataxics face difficulty in performing visually guided arm movements because the relevant perceptual systems output their pragmatic representations incorrectly. Here, I argue that it is not enough to say that pragmatic representations are output incorrectly; we also need to know why they are output that way. Given recent evidence that optic ataxia impairs (...) peripersonal space representation, I argue that pragmatic representations are output incorrectly because the organizing principle of the vision-for-action system is blocked by optic ataxia. I then show how this means that this principle, not pragmatic representations, is the representational state that mediates between perception and action, i.e. the principle, not pragmatic representations, is the immediate mental antecedent of action.

Why games? How could anyone consider action games an experimental paradigm for Cognitive Science? In 1973, as one of three strategies he proposed for advancing Cognitive Science, Allen Newell exhorted us to “accept a single complex task and do all of it.” More specifically, he told us that rather than taking an “experimental psychology as usual approach,” we should “focus on a series of experimental and theoretical studies around a single complex task” so as to demonstrate that our theories (...) of human cognition were powerful enough to explain “a genuine slab of human behavior” with the studies fitting into a detailed theoretical picture. Action games represent the type of experimental paradigm that Newell was advocating and the current state of programming expertise and laboratory equipment, along with the emergence of Big Data and naturally occurring datasets, provide the technologies and data needed to realize his vision. Action games enable us to escape from our field's regrettable focus on novice performance to develop theories that account for the full range of expertise through a twin focus on expertise sampling and longitudinal studies of simple and complex tasks.

Increasing computational power and improving deep learning methods have made computer vision technologies pervasively common in urban environments. Their applications in policing, traffic management, and documenting public spaces are increasingly common (Ridgeway 2018, Coifman et al. 1998, Sun et al. 2020). Despite the often-discussed biases in the algorithms' training and unequally borne benefits (Khosla et al. 2012), almost all applications similarly reduce urban experiences to simplistic, reductive, and mechanistic measures. There is a lack of context, depth, and specificity in (...) these practices that enables semantic knowledge or analysis within urban contexts, especially within the context of using and occupying urban space. This paper will critique existing uses of artificial intelligence and computer vision in urban practices to propose a new framework for understanding people, action, and public space. This paper revisits Geertz's (1973) use of thick descriptions in generating interpretive theories of culture and activity and uses this lens to establish a framework to approach evaluating the varied uses of computer vision technologies that weigh meaning. By discussing cases of implemented examples of urban computer vision—from LinkNYC and Numina's urban measurements to the Detroit Police's use of DataWorks Plus's facial recognition technology—it proposes a framework for evaluating the thickness of the algorithm's conclusions against the computational method's complexity required to produce that outcome. Further, we discuss how the framework's positioning may differ (and conflict) between different users of the technology, from engineer to urban planner and policymaker, to citizen. This paper also discusses how the current use and training of deep learning algorithms and how this process limits semantic learning and proposes three potential methodologies toward gaining a more contextually specific, urban-semantic, description of urban space relevant to urbanists. This paper contributes to the critical conversations regarding the proliferation of artificial intelligence by challenging the current applications of these technologies in the urban environment by highlighting their failures within this context while also proposing an evolution of these algorithms that may ultimately make them sensitive and useful within this spatial and cultural milieu.

In other words, I argue that Dewey's definition of art as experience has a very fruitful transformational potential.3By defining art as experience, Dewey also sought to dissolve the binary structures of aesthetic rifts: art and life, high art and low art, body and mind, subject and object, self and world, emphasizing the holistic action in our engagement with art.4 But according to Dewey, the divisor of art from life and thus to blame for the aesthetic barrenness of our lived reality is the museum institution, as Shusterman describes: [End Page 91]The compartmentalization and spiritualization of art as an elevated "separate realm" set "upon a far-off pedestal," divorced from the materials and aims of other human effort, has removed art from the lives of most of us, and thus impoverished the aesthetic quality of our lives.(PA, 19)However, we must keep in mind that Art as Experience was published in 1934. Today, new approaches towards encounter and engagement within public museums are taking form and gaining momentum, with unprecedented directorial visions and mandates designed to nurture and make accessible art-based experiences among diverse audiences — where art and life can meet via multiple approaches. Theoretical synchronicities between pragmatist approaches to aesthetics and fruitful museum experiences can be suggested upon consideration of various innovative programs and approaches initiated at the Tate Modern in London and the Baltic Center for Contemporary Art in Gateshead. The overwhelming success of both venues could signify a reengagement of the general public with contemporary art, fed by "democratic," participatory approaches to exhibiting and programming art that make the museum more accessible to the various mixed publics it serves. In light of these new museological developments, Dewey's polemic oppositions between his conceptualizations of the museum experience and "art-as-experience" should be reexamined and possibly redefined.Dewey was entirely opposed to the concept of "art for art's sake." By exonerating art of any functional value — deeming it "fine" — art was elevated to a position separate from life, and thus rendered impotent to effect a lived aesthetic experience (which is how, Dewey would argue, the arts function most powerfully — as the purveyors of heightened experience). As Shusterman describes:The underlying motive for such attempts to purify art from any functionality was not to denigrate it as worthlessly useless, but to place its worth apart from and above the realm of instrumental value...and this freedom from use would be its defining and ennobling feature.(PA, 9)Dewey (and Shusterman) thus maintained that the very power construct that put the "fine" in art did so by removing the aspect of function from it.

Modern society has undergone a fundamental change to a society built around purposively established organizations. Social theory in this context can be a guide to social construction. Foundations of Social Theory is dedicated to this aim. Being oriented towards the design of social institutions it has to choose a voluntaristic, purposive theory of action and must make the behavior of social systems explainable in terms of the combination of individual actions. It has to deal with the emergence and maintenance (...) of norms and rights, the concepts of authority, trust, law and legitimacy, the viability of organizations and the efficiency of social systems. But more important than the specific points is the vision of a new role for social theory in an increasingly constructed social environment. This vision is the motivation behind Foundations of Social Theory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rethinking Social Action through Music: The Search for Coexistence and Citizenship in Medellín’s Music Schools by Geoffrey BakerKim BoeskovGeoffrey Baker: Rethinking Social Action through Music: The Search for Coexistence and Citizenship in Medellín’s Music Schools (Cambridge, UK: Open Book Publishers, 2021)If indeed there exists, as Geir Johansen has proposed,1 a self-critical movement within the field of music education, Geoffrey Baker is undoubtedly one of its leading (...) figures. According to Johansen, the self-critical turn is characterized by an increasing number of music educators directing criticism toward music education itself by denouncing overly romantic visions of “the power of music” and scrutinizing how music educational practices are implicated in the propulsion of problematic social forces of inequality, oppression, and injustice. Baker’s widely read book from 2014, El Sistema: Orchestrating Venezuela’s Youth,2 thoroughly denounced the globally acclaimed Venezuelan ‘musical miracle’ as a myth. Based on extensive field work in Venezuela, Baker painstakingly dissected El Sistema as an archaic, morally, and pedagogically flawed model of music education veiled in the empty rhetoric of music as a tool of social redemption and documented how such models are ripe with opportunities for abuse, in every sad sense of the word.The continuation of Baker’s critical project is published in the form of a four-hundred-page book, entitled Rethinking Social Action Through Music. Baker presents the text as “a ‘post-El Sistema’ project”3 as it constitutes a departure [End Page 92] from his preoccupation with ‘The System’ toward potential alternatives to the Venezuelan model. He finds such an alternative in the Red (Red de Escuelas de Música de Medellín), a network of music schools in the Colombian city of Medellín, which figures as the center of attention in Baker’s institutional ethnography. However, even as the Colombian institution is invoked as a counterexample to its Venezuelan sibling, the Red is not held up for its ability to enact social change or display of innovative pedagogical principles. What Baker finds exemplary and worthy of investigation is the willingness he locates within the administrative layer of the Red to continuously engage in reflective work with regards to the tensions, conflicts, and pitfalls, as well as potentials of musical-social work. Particularly, Baker’s attention is directed to the decision-making processes and discussions among the leaders of the institution; how senior staff members adopt self-critical stances, how needs for institutional change are recognized, the recurring frictions between musical staff and members of the institution’s social team, and tensions between public statements expressing confidence in the program’s efficacy and internal conversations full of ambivalence and doubt.It is with reference to the reflexive processes of the Red that Baker conducts insightful and well-informed discussions of a range of themes relevant to music educators and scholars. Baker situates his analysis within the wider landscape of SATM (Social Action Through Music), which can roughly be understood as the field of musical practice emanating from the large socio-musical orchestral programs conceived in Latin America in the last decades of the 20th century and subsequently spread as ‘Sistema-inspired’ offspring throughout the globe in the beginning of the 21st century. Yet, the discussions found in this book are easily connected to pertinent themes of the philosophy and sociology of music education, such as the notion of artistic citizenship, decolonization, the political nature of music education, ‘the social’ in music education, to name a few. One of the striking qualities of this book is its ability to identify important issues in the local context of Medellín, extract the underlying mechanisms and through empirical examples unfold a much broader discussion of what social justice and social change might mean in the field of music education. Baker, originally educated as an ethnomusicologist, reflects on these topics with depth and nuance, underscoring the relevance of approaching these complex issues through ethnographic work, rather than basing such discussions solely on conceptual exploration.Appearing as a red line throughout the book is Baker’s insistence on foregrounding the ambiguity and ambivalence of musical-social work. In fact, his critical encounter with the field... (shrink)
