In this paper, I argue for three claims. The first is that the difference between analog and digital representation lies in the format and not the medium of representation. The second is that whether a given system is analog or digital will sometimes depend on facts about the user of that system. The third is that the first two claims are implicit in Haugeland's (1998) account of the distinction.

Cognitive representations are typically analysed in terms of content, vehicle and format. While current work on formats appeals to intuitions about external representations, such as words and maps, in this paper we develop a computational view of formats that does not rely on intuitions. In our view, formats are individuated by the computational profiles of vehicles, i.e., the set of constraints that fix the computational transformations vehicles can undergo. The resulting picture is strongly pluralistic, it makes space for a (...) variety of different formats, and is intimately tied to the computational approach to cognition in cognitive science and artificial intelligence.

Carey has argued that there is a system of core numerical cognition – the analog magnitude system – in which cardinal numbers are explicitly represented in iconic format. While the existence of this system is beyond doubt, this paper aims to show that its representations cannot have the combination of features attributed to them by Carey. According to the argument from abstractness, the representation of the cardinal number of a collection of individuals as such requires the representation of (...) individuals as such, and this in turn requires non-iconic format, from which it is concluded that the explicit representation of the cardinal number of some individuals requires non-iconic representational format. In support of the first premise, an account is given of what approximate cardinal numbers might be, and in support of the second, a direct argument is articulated and defended. Finally, in response to an objection, a second argument for the central thesis is provided. While the discussion is couched in the terms of Carey’s work, the considerations it adduces are perfectly general, and the conclusion should therefore be taken into consideration by all those aiming to characterize the AM system.

Cognitive Theories of emotions have enjoyed great popularity in recent times. Allegedly, the so-called Perceptual Theory constitutes the most attractive version of this approach. However, the Perceptual Theory has come under increasing pressure. There are at least two ways to deal with the barrage of objections, which have been mounted against the Perceptual Theory. One is to argue that the objections work only if one assumes an overly narrow conception of what perception consists in. On a better and more liberal (...) understanding of perception, the objections lose their force. The other is to stress that the differences between emotions and sensory perceptions can be explained by focusing on a new analogy. As I will argue, emotions have interesting similarities with magnitude representations, such as the representation of distance. Such representations are plausibly thought to be analog and non-conceptual, but by contrast to sensory perceptions, such as colour perceptions, they do not lie at the sensory periphery. This new analogy makes room for a novel and attractive theory of emotions, the Receptive Theory, which allows for a positive and epistemologically fruitful characterization of emotions. (shrink)

I argue that analogue mental representations possess a canonical decomposition into privileged constituents from which they compose. I motivate this suggestion, and rebut arguments to the contrary, through reflection on the approximate number system, whose representations are widely expected to have an analogue format. I then argue that arguments for the compositionality and constituent structure of these analogue representations generalize to other analogue mental representations posited in the human mind, such as those in early vision and visual imagery.

An influential objection to the epistemic power of the imagination holds that it is uninformative. You cannot get more out of the imagination than you put into it, and therefore learning from the imagination is impossible. This paper argues, against this view, that the imagination is robustly informative. Moreover, it defends a novel account of how the imagination informs, according to which the imagination is informative in virtue of its analog representational format. The core idea is that (...) class='Hi'>analog representations represent relations ‘for free,’ and this explains how the imagination can contain more information than is put into it. This account makes important contributions to both philosophy of mind, by showing how the imagination can generate new content that is not represented by a subject’s antecedent mental states, and epistemology, by showing how the imagination can generate new justification that is not conferred by a subject’s antecedent evidence.

The capacity for feature binding is typically explained in terms of the attribution model: a perceptual state selects an individual and attributes properties to it (Kahneman & Treisman 1984; Clark 2004; Burge 2010). Thus features are bound together in virtue of being attributed to the same individual. While the attribution model successfully explains some cases of binding in perception, not all binding need be understood as property attribution. This chapter argues that some forms of binding—those involving holistic iconic representations, which (...) bind features outside the limits of attention and object files—don’t fit the attribution model. The chapter then sketches an alternative coordination model of binding that construes icons as complex analog representations. (shrink)

The imagination is ubiquitous in our cognitive lives. You might imagine rotating a puzzle piece to determine whether it fits in an open space, or imagine what things are like from another person's perspective to figure out how they are feeling, or imagine a new rug in your living room to determine whether it matches the color of your sofa. These examples are mundane, but they point to a deep philosophical puzzle: how could merely imagining something give you any reason (...) to believe that it is true? After all, you can imagine anything you want to, from the fictional to the fantastical. This has led many philosophers to be deeply skeptical of the epistemic value of the imagination. When imagination is accorded a justificatory role, it is typically limited to beliefs about what is metaphysically possible. More recently, some philosophers have begun to push back against this orthodoxy by arguing that the imagination can justify empirical beliefs about the actual world. But even then, most contemporary discussions focus on whether the imagination can justify empirical belief, rather than on how the imagination justifies empirical belief, thereby leaving many central questions about the epistemology of the imagination unanswered. This dissertation attempts to fill this lacuna by canvassing the theoretical landscape of this exciting new literature and developing an account of the epistemic structure of the imagination. The first chapter sets the stage for the rest of the dissertation by reviewing extant arguments for and against the view that the imagination can justify empirical belief before posing a new argument in its favor. The second chapter argues that imaginative justification is mediate but non-inferential; it depends on one’s prior justification without depending on an inference from one’s prior beliefs. The third chapter argues that the imagination is informative—it can represent new content and generate new justification—in virtue of its analog representational format. The fourth and final chapter argues that some imaginings just are beliefs, and that this grounds their justificatory force. Together, the arguments of this dissertation suggest that the imagination is a distinctive kind of ampliative reasoning, and that it plays this cognitive and epistemic role by combining the analog representational format of imagery with the evidence-sensitive function of belief.

This paper refines a controversial proposal: that core systems belong to a perceptual kind, marked out by the format of its representational outputs. Following Susan Carey, this proposal has been understood in terms of core representations having an iconic format, like certain paradigmatically perceptual outputs. I argue that they don’t, but suggest that the proposal may be better formulated in terms of a broader analogue format type. Formulated in this way, the proposal accommodates the existence of genuine (...) icons in perception, and avoids otherwise troubling objections. (shrink)

It is often claimed that pre-attentive vision has an ‘iconic’ format. This is seen to explain pre-attentive vision's characteristically high processing capacity and to make sense of an overlap in the mechanisms of early vision and mental imagery. But what does the iconicity of pre-attentive vision amount to? This paper considers two prominent ways of characterising pre-attentive visual icons and argues that neither is adequate: one approach renders the claim ‘pre-attentive vision is iconic’ empirically false while the other obscures (...) its ability to do the explanatory work, which motivates positing pre-attentive visual icons in the first place. With this noted, I introduce the notion of an ‘Analogue Map’ and argue that it provides a superior characterisation of pre-attentive vision's iconicity. I then argue that this forces a reassessment of debates which have traditionally presupposed the iconicity of pre-attentive vision, emphasising ramifications for the viability of a format-based perception-thought border.

Perceptual systems respond to proximal stimuli by forming mental representations of distal stimuli. A central goal for the philosophy of perception is to characterize the representations delivered by perceptual systems. It may be that all perceptual representations are in some way proprietarily perceptual and differ from the representational format of thought (Dretske 1981; Carey 2009; Burge 2010; Block ms.). Or it may instead be that perception and cognition always trade in the same code (Prinz 2002; Pylyshyn 2003). This paper (...) rejects both approaches in favor of perceptual pluralism, the thesis that perception delivers a multiplicity of representational formats, some proprietary and some shared with cognition. The argument for perceptual pluralism marshals a wide array of empirical evidence in favor of iconic (i.e., image-like, analog) representations in perception as well as discursive (i.e., language-like, digital) perceptual object representations.

Empirical discussions of mental representation appeal to a wide variety of representational kinds. Some of these kinds, such as the sentential representations underlying language use and the pictorial representations of visual imagery, are thoroughly familiar to philosophers. Others have received almost no philosophical attention at all. Included in this latter category are analogue magnitude representations, which enable a wide range of organisms to primitively represent spatial, temporal, numerical, and related magnitudes. This article aims to introduce analogue magnitude representations to a (...) philosophical audience by rehearsing empirical evidence for their existence and analysing their format, their content, and the computations they support. 1 Background1.1 Evidence of analogue magnitude representations1.2 Weber’s law1.3 Scepticism about analogue magnitude representations2 Format2.1 Carey’s analogy2.2 Neural realization2.3 Analogue representation2.4 Analogue magnitude representation components3 Content3.1 Do analogue magnitude representations have representational content?3.2 What do analogue magnitude representations represent?3.3 What content types do analogue magnitude representations have?4 Computations4.1 Arithmetic computation4.2 Practical deliberation5 Conclusion.

This is the first of a three-volume collection of David Lewis's most recent papers in all the areas to which he has made significant contributions. The purpose of this collection (and the two volumes to follow) is to disseminate even more widely the work of a preeminent and influential late twentieth-century philosopher. The papers are now offered in a readily accessible format. This first volume is devoted to Lewis's work on philosophical logic from the last twenty-five years. The topics (...) covered include: deploying the methods of formal semantics from artificial formalised languages to natural languages, model-theoretic investigations of intensional logic, contradiction, relevance, the differences between analog and digital representation, and questions arising from the construction of ambitious formalised philosophical systems. The volume will serve as an important reference tool for all philosophers and their students. (shrink)

To know is to cognize, to cognize is to be a culturally bounded, rationality-bounded and environmentally located agent. Knowledge and cognition are thus dual aspects of human sociality. If social epistemology has the formation, acquisition, mediation, transmission and dissemination of knowledge in complex communities of knowers as its subject matter, then its third party character is essentially stigmergic. In its most generic formulation, stigmergy is the phenomenon of indirect communication mediated by modifications of the environment. Extending this notion one might (...) conceive of social stigmergy as the extra-cranial analog of an artifcial neural network providing epistemic structure. This paper recommends a stigmergic framework for social epistemology to account for the supposed tension between individual action, wants and beliefs and the social corpora. We also propose that the so-called "extended mind" thesis offers the requisite stigmergic cognitive analog to stigmergic knowledge. Stigmergy as a theory of interaction within complex systems theory is illustrated through an example that runs on a particle swarm optimization algorithm. (shrink)

An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on. Here, I examine the grounds for making much more specific claims about how mental states are structured from constituent parts. For example, the state I am in when I perceive the shape of a mountain ridge may have as constituent parts my representations of the shapes of each peak and (...) saddle of the ridge. More specific structural claims of this sort are a guide to how mental states fall within broader representational kinds. Moreover, these claims have significant implications of their own about semantic, functional, and epistemic features of our mental lives. But what are the conditions on a mental state's having one type of constituent structure rather than another? Drawing on explanatory strategies in vision science, I argue that, other things being equal, the constituent structure of a mental state determines what I call its distributional properties—namely, how mental states of that type can, cannot, or must co‐occur with other mental states in a given system. Distributional properties depend critically on and are informative about the underlying structures of mental states, they abstract in important ways from aspects of how mental states are processed, and they can yield significant insights into the variegation of psychological capacities.

Publishers love titles that begin How or Why. Better still, How and Why, combining edification with utility. The target group is that overlap between the self-help audience and the idly curious—which is to say, most of us. And since emotions are very much about self-help and self-harm, they offer rich pickings in a burgeoning market. Flanagan's How to Do things with Emotions is a philosopher's take on moral emotions, the allusion to J. L. Austin's How to Do Things with Words (...) chiming with the self-help milieu. Reviewing cases, Flanagan points out that most scientific work in this field derives from experiments on psychology students, about as unrepresentative a slice of humanity as you could find. For Flanagan, they are too WEIRD (Western, Educated, Industrialized, Rich, Democratic) to tell us much about the non-weird majority. To learn to “do emotions better,” he argues, we have to look farther afield. Although the emotional lives of cultural others are surely different from those taking Psychology 101, at some functional level they might be similar. Work out the conceptual logic and practical rationale of culturally elaborated emotions—Minangkabau “shame,” Ifaluk “righteous anger,” American “road rage”—and there is scope for comparison. Indeed, anthropology has shown as much, and it is from anthropology that Flanagan takes his cues. To mention two famous cases, what can we learn about anger management from Utku igloo-dwellers and Ilongot headhunters? Mutually dependent for survival in their snowy isolation, the Utku cannot risk getting angry. (They mercilessly tease their children into learning the futility of anger.) In the jungles of Luzon, Ilongot youths cast away their anger in externally directed violence: headhunting as cathartic sport. We can think of parallels closer to home.Flanagan's vigorously argued book, a tour de force of its kind, is both an anatomizing of anger and shame—two moral emotions we tend to “do badly”—and a proposal to “change how we do these emotions.” Indignation is fine, but anger that is vengeful or “pain-passing,” rather than righteous, is irrational and socially harmful. Shame can be incapacitating and cruel (the undeserved burn of a Twitter pile-on). What we need is reflective anger directed at injustice and a “mature sense of shame” that reminds us of the social contract and stops us misbehaving.In its How-and-Why format, the book combines theory and practice, metaethics with moralism. Here is how a prof should do self-help. But if the diagnosis is well made, the remedy is hard to imagine. As Flanagan recognizes, moral sentiments and practices are embedded in intricate forms of life and not readily detachable. Anger Utku-style is not a transferable skill, nor are educative routines forged in social ecologies remote from our own. Lacking serviceable models, Flanagan falls back on the anthropological justification that knowledge of cultural diversity expands our sense of human possibility, of other roads taken. In a globalizing world, difference is its own reward. For me, an anthropologist, that maxim is enough. Yet difference bedevils comparison, jinxing the units, warping criteria. Most languages lack a word for emotion or an equivalent umbrella concept; nor do emotion words translate well across languages. Emotion may be an incoherent notion, or at best a heuristic.Flanagan's use of the WEIRD tag makes things a bit too easy. Does it cover farmhands and factory workers? Are we so democratic, anyway? More damagingly, a typological approach blurs the circumstances of family, community, and biography that define an emotional episode and shape its phenomenology, the way it is felt and experienced—what a violent outburst or fearful exit means in the context of a life. Take Joseph Conrad's Lord Jim, who flees a scene of failure and derails his life. It requires a long narrative to unravel the implications of his jumping ship and the paralyzing shame he experiences before the judgment of society. Or consider the scene in Anna Karenina in which the dignified and self-important Karenin, apprised of Anna's adulterous liaison, agonizes over the threat to his existence. To call his response jealousy would not scratch the surface. Characteristically for Tolstoy, the emotions go unnamed. Instead, we witness Karenin's fervid deliberations (emotions involve thoughts), vacillations (emotions have action tendencies), anguished calculations of impending scandal (emotions are appraisals), and bodily changes (emotions are cognized feelings). We shudder at the brutal metaphors through which he grasps his predicament and its cure: like rooting out a bad tooth, he decides. That welter of particularities escapes the theorist who needs clear-cut, comparable units, formulaic instances of jealousy or anger. But what are you left with if you omit the details? What would remain of Karenin's existential crisis?The novelist's privileged access to subjectivity is, of course, unavailable to the scientist, but the larger context of plot and character—a history of relations that gives emotional episodes their shape and power—has its analog in the ethnographic domain. Emotions are public as well as private events, their meanings and effects depending on a fit with social reality, a clash of perspectives. In thought and feeling, we are never really alone. All of which suggests that narrative, fictional or nonfictional, can capture the ongoing moment in a way that eludes other methods. If what we are after is living emotion, it is the movie, not the snapshot, that surely matters. No point in comparing “emotions” no one ever really experienced outside of an experiment.But there's the rub. In generalization—the goal of emotion theory—an emotion's social meaning, personal significance, pragmatic function, and narrative context get stripped out. All that makes it what it is! Even in doggedly empirical anthropology, detailed emotional episodes are rare (Jean Briggs's Utku ethnography Never in Anger, published in 1970, is still unsurpassed). Instead we get recollections and summary examples, lacking the constitutive detail, real-time evolutions, and consequences of the real thing. Yet these must serve for comparison, fodder for countless theoretical speculations. Are we at risk of analyzing faux emotions and building theories on cardboard constructions?An empty Arctic stage, a handful of characters, life simplified to survival: Briggs is a hard act to follow. Bare life does not make for basic emotions. On the white set, emotions prove hard to parse. That gruff hesitation, that flashing glint—are they tokens of anger? Empathy will not suffice. As Briggs shows, narrative context is all. And in our more cluttered emotional worlds, the value of backstory, interwoven biographies, and emotional plots is all the greater. Flanagan is right; we must do emotions better. (shrink)

The Bhagavad Gītā occurs at the start of the sixth book of the Mahābhārata—one of South Asia’s two main epics, formulated at the start of the Common Era (C.E.). It is a dialog on moral philosophy. The lead characters are the warrior Arjuna and his royal cousin, Kṛṣṇa, who offered to be his charioteer and who is also an avatar of the god Viṣṇu. The dialog amounts to a lecture by Kṛṣṇa delivered on their chariot, in response to the fratricidal (...) war that Arjuna is facing. The symbolism employed in the dialog—a lecture delivered on a chariot—ties the Gītā to developments in moral theory in the Upaniṣads. The work begins with Arjuna articulating three objections to fighting an impending battle by way of two teleological theories of ethics, namely Virtue Ethics and Consequentialism, but also Deontology. In response, Kṛṣṇa motivates Arjuna to engage in battle by arguments from procedural ethical theories—specifically his own form of Deontology, which he calls karma yoga, and a radically procedural theory unique to the Indian tradition, Yoga, which he calls bhakti yoga. This is supported by a theoretical and metaethical framework called jñāna yoga. While originally part of a work of literature, the Bhagavad Gītā was influential among medieval Vedānta philosophers. Since the formation of a Hindu identity under British colonialism, the Bhagavad Gītā has increasingly been seen as a separate, stand-alone religious book, which some Hindus treat as their analog to the Christian Bible for ritual, oath-swearing, and religious purposes. The focus of this article is historical and pre-colonial. (shrink)

Data from neuropsychology do not support the idea that the primary visual cortex necessarily displays internal visual images. However, the choice of formats used in human cognition is not restricted to depictive or descriptive representations. Nestled between pictures and propositions, primitive spatial schemas with simple analog features extracted from pictorial scenes may play a subtle but wide role in cognition.

Using quantum liquids one can simulate the behavior of the quantum vacuum in the presence of the event horizon. The condensed matter analogs demonstrate that in most cases the quantum vacuum resists formation of the horizon, and even if the horizon is formed different types of the vacuum instability develop, which are faster than the process of Hawking radiation. Nevertheless, it is possible to create the horizon on the quantum-liquid analog of the brane, where the vacuum life-time is long (...) enough to consider the horizon as the quasistationary object. Using this analogy we calculate the Bekenstein entropy of the near-extremal and extremal black holes, which comes from the fermionic microstates in the region of the horizon—the fermion zero modes. We also discuss how the cancellation of the large cosmological constant follows from the thermodynamics of the vacuum. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reclaiming the Integration of Body and MindDeborah SpragueThe week before New Year’s Day has often spurred me to evaluate my personal path. I courted my own permission to apply to graduate school, charting scenarios, figuring options, but still I held back. Browsing the Colgate Rochester Crozer Divinity School website, I found a unique course offering: Deepening the Heart of Wisdom: Buddhist Christian Contemplative Practice and Dialogue. I knew I (...) had to take it! Class was going to start in a week and as yet I hadn’t even applied to the school’s graduate program. In a flurry I requested transcripts, garnered recommendations, and considered childcare options. My desire to engage this particular dialogue grew through my Christian practice of Centering Prayer1 and my Episcopal parish’s contemplative interfaith Vital Conversations program.These vital conversations began with an intentional time of silence in which we prepared the “eye of the heart” to perceive the conversation at a deeper level. Our rector invited a guest from a different faith tradition each month.2 He engaged the guest in questions and dialogue regarding his or her spiritual practices and personal story. Then, the guest received questions from the group. After hearing a Buddhist guest and visiting the local Zen center, I knew my own spiritual formation would be broadened and deepened by taking the two-week, intensive format course. Because actual spiritual practice from both traditions comprised a significant portion of the class, I surmised this course would foster a more complete, integrated form of understanding the two traditions.This essay will explore the contemplative pedagogy of this course, wherein the instructors hoped “students [would] walk away with a visceral understanding of these traditions as full-body disciplines for transforming the mind and heart.”3 First, I will give a brief description of the class participants and discuss the types of spiritual practices we encountered from each tradition. Then, I will share my experiences related to those practices and how the structure of the course supported an integrated epistemology. Finally, I will consider the phenomenon of Christian interest in Buddhist practices and what that implies about popular Christianity and its potential to become a fuller version of itself. [End Page 101]The student population of this class was largely Christian, with some Unitarian Universalists, a pagan, and an agnostic as well. That said, the spectrum of Christians reflected mainline denominations as well as some persons with roots in Catholicism and Eastern Orthodoxy. As might be expected from a varied group, the Christologies of participants varied from creedal to acreedal. This group came together to participate in a variety of Christian and Zen Buddhist spiritual practices.The class engaged the following practices according to Sōtō Zen: zazen, contemplative walking as a group, and, near the end of the course, Rev. Dr. Hickey led us in a portion of the Sōtō-shū morning service. Every class began with at least fifteen minutes of zazen, which gradually increased as the class progressed. Daily practice of the same meditation technique allowed us to enter that particular practice in a sustained way.In contrast to our Zen practice, we experienced a different type of Christian spiritual practice with each class session. This approach acquainted students with a variety of traditions but did not allow experiential depth in any one particular mode. The students and instructors took part in Taizé chanting,4 chanting of the Psalms from the Daily Office, lectio divina,5 praying with icons,6 the Jesus Prayer,7 the Rosary,8 and two guided reflections: an Ignatian9 meditation on a gospel text, and a meditation developed by Christian contemplative Anthony De Mello. I wondered how our experience of the class would have changed had the Christian practice focused on one or two types, in a sustained, daily manner. Perhaps the rationale for surveying a wide variety of practices reflected the need for Western Christians to gain familiarity with their own contemplative traditions.I consider Christianity’s analog to zazen to be Centering Prayer, because it is also based in no-thought. However, Centering Prayer was not included in our experience of spiritual practices. If we conceive of two... (shrink)

The author, who was Schrödinger's assistant during his last years in Vienna, gives an account of Schrödinger's views and activities during that time which lead him to a different approach to research on the relations between gravitation and quantum phenomena. Various features of past research are outlined in nontechnical terms. A heuristic argument is presented for the role of the zero-point energy of massive particles in counteracting gravitational collapse and the formation of horizons. Arguments are presented for the view that (...) progress in describing extreme gravitational phenomena can be achieved by the new outlook obtained from the introduction of the analog of Maxwell's vacuum displacement term with a quasiconstant parameter, rather than from renormalization of special processes, even if this is successful. The results can be expected to be in accord with Schrödinger's conjectures.A physical interpretation for the change of sign of the differential invariant of Karlhede, Lindström, and Åman at the horizon is suggested.Some important historical details about Schrödinger are touched upon.

The use of aggregated quality of life estimatesin the formation of public policy and practiceguidelines raises concerns about the moralrelevance of variability in values inpreferences for health care. This variabilitymay reflect unique and deeply held beliefs thatmay be lost when averaged with the preferencesof other individuals. Feminist moral theorieswhich argue for attention to context andparticularity underline the importance ofascertaining the extent to which differences inpreferences for health states revealinformation which is morally relevant toclinicians and policymakers. To facilitatethese considerations, we present (...) an empiricalstudy of preferences for the timing andoccurrence of health states associated withhormone replacement therapy (HRT). Sixteenwomen between the ages of 45 and 55 wereenrolled in this pilot study. Theirpreferences regarding five health statesassociated with HRT (menopausal symptoms, sideeffects of HRT, breast cancer, myocardialinfarction, and osteoporosis) were assessed inquantitative terms known as utilities. Twostandard methods, the visual analog scale (VAS) and the standard gamble (SG), were used toassess utility and time preference (calculatedas a discount rate). The wide variability ofresponses underlines the importance oftailoring health care to individual women'spreferences. Policy guidelines whichincorporate utility analysis must recognize thenormative limitations of aggregatedpreferences, and the moral relevance ofindividual conceptions of health. (shrink)

When characterizing the content of a subject’s perceptual experience, does their seeing an object entail that their visual experience represents it as being a certain way? If it does, are they thereby in a position to have perceptually-based thoughts about it? On one hand, representationalists are under pressure to answer these questions in the affirmative. On the other hand, it seems they cannot. This paper presents a puzzle to illustrate this tension within orthodox representationalism. We identify several interesting morals which (...) may be drawn in response, each of which teaches us something interesting and important about perceptual experience and its interface with cognition and related phenomena.

We concur with Cohen Kadosh & Walsh (CK&W) that representation of numbers in the parietal cortex is format dependent. In addition, we suggest that all formats do not automatically, and equally, access analog magnitude representation in the intraparietal sulcus (IPS). Understanding how development, learning, and context lead to differential access of analog magnitude representation is a key question for future research.

Perceptual representations are sometimes said to be iconic, or picture-like. But what does this mean, and is it true? I suggest that the most fruitful way to understand iconicity is in terms of similarity, but there are three importantly different grades of similarity that that might hold between perceptual representations and their objects, and these should be distinguished. It is implausible that all perceptual representations achieve even the weakest grade of iconicity, but I speculatively suggest a “Kantian” view, whereby all (...) perceptual representation involves fillers placed in a “strongly iconic” spatial framework. Those fillers will likely be hybrid structures, with varying grades of iconicity combined with non-iconic elements. (shrink)

In 1972, in Chile, the German designer Gui Bonsiepe was in charge of the Industrial Design Department of Technological Institute of the National Corporation for the Promotion of Production INTEC Corfo, during the government of socialist President Salvador Allende in Chile. In this article from the INTEC magazine n.2, published this time for the first time in English, Bonsiepe develops a theoretical formulation, applied to the field of design, through which he proposes a concept that will be fundamental in the (...) field of interactive development, both analog and digital: the Interface. Thus, it also includes concepts of cybernetics such as variability and predictive study of behavior in the field of projecting disciplines. Bonsiepe is an exceptional representative during the formation of the iconic Hochschule für Gestaltung in Ulm. And among other elements, one very outstanding was his time as a student of Professor Max Bense and Horst Rittel, who would have introduced the concepts of first-order Cybernetics in the teaching of communication, and the design of information, in a pioneering way. The challenge posed in 1972, in Chile, focused on the possibility of calculating elements of criticism of political economy, in the field of knowledge generated by sensitive experiences, "calculating the use value" of the field of esthetics. As a renowned disciple of Max Bense and Tomas Maldonado, Bonsiepe represents the meeting of two Cybernetic traditions, collaborating with the emblematic Cybersyn Corfo project, in which the formulation of interaction mechanisms was strategic in combination with Stafford Beer's approaches to a second-order Cybernetics, according to the Viable System Model, for a project of decentralized state production, and transmission of information in real time.

Over the past 50 years, philosophers and psychologists have perennially argued for the existence of analog mental representations of one type or another. This study critically reviews a number of these arguments as they pertain to three different types of mental representation: perceptual representations, imagery representations, and numerosity representations. Along the way, careful consideration is given to the meaning of “analog” presupposed by these arguments for analog mental representation, and to open avenues for future research.

Representation is central to contemporary theorizing about the mind/brain. But the nature of representation--both in the mind/brain and more generally--is a source of ongoing controversy. One way of categorizing representational types is to distinguish between the analog and the digital: the received view is that analog representations vary smoothly, while digital representations vary in a step-wise manner. I argue that this characterization is inadequate to account for the ways in which representation is used in cognitive science; in its (...) place, I suggest an alternative taxonomy. I will defend and extend David Lewis's account of analog and digital representation, distinguishing analog from continuous representation, as well as digital from discrete representation. I will argue that the distinctions available in this four-fold account accord with representational features of theoretical interest in cognitive science more usefully than the received analog/digital dichotomy. (shrink)

Analog representation is often cast in terms of an engineering distinction between smooth and discrete systems. The engineering notion cuts across interesting representational categories, however, so it is poorly suited to thinking about kinds of representation. This paper suggests that analog representations support a pattern of interaction, specifically open-ended searches for content across levels of abstraction. They support the pattern by sharing a structure with what they represent. Continuous systems that satisfy the engineering notion are exemplars of this (...) kind because they are uninterpretable unless they are structure-preserving. Analog representations, so understood, include pictures, images, diagrams, and most graphs. This conception of analogicity also fits well with a line of thought about what makes perceptual states distinctive: they satisfy a “parts principle”. (shrink)

Recently, a cottage industry has formed with the goal of analyzing reasoning. The relevant notion of reasoning in which philosophers are expressly interested is fixed through an epistemic functional description: reasoning—whatever it is—is our personal-level, rationally evaluable means of meeting our rational requirements through managing and updating our attitudes. Roughly, the dominant view in the extant literature as developed by Paul Boghossian, John Broome, and others is that reasoning is a rule-governed operation over propositional attitudes that results in a change (...) in attitude. In this paper, I argue that our personal-level operations over mental models and visuospatial imagery, which are representations in a non-propositional/analogue format, can be rationally evaluable processes of managing our attitudes and, thus, should be considered reasoning in the relevant sense. Furthermore, I show that if reasoning can occur through operations over mental models and imagery, then the dominant rule-following account mischaracterizes the cognitive operations and representational states assumed to be constitutive of reasoning and what grounds the rational status of a line of reasoning.

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three (...) independent ways in which a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

Characterizing different kinds of representation is of fundamental importance to cognitive science, and one traditional way of doing so is in terms of the analog–digital distinction. Indeed the distinction is often appealed to in ways both narrow and broad. In this paper I argue that the analog–digital distinction does not apply to representational schemes but only to representational systems, where a representational system is constituted by a representational scheme and its user, and that whether a representational system is (...) analog or non-analog depends on facts about that user. This aspect of the distinction has gone unnoticed, and I argue that the failure to notice it can be an impediment to scientific progress. (shrink)

The distinction between analog and digital representation is reexamined; it emerges that a more fundamental distinction is that between symbolic and analog simulation. Analog simulation is analyzed in terms of a (near) isomorphism of causal structures between a simulating and a simulated process. It is then argued that a core concept, naturalistic analog simulation, may play a role in a bottom-up theory of adaptive behavior which provides an alternative to representational analyses. The appendix discusses some formal (...) conditions for naturalistic analog simulation. (shrink)

In the 1980s, a number of philosophers argued that perception is analog. In the ensuing years, these arguments were forcefully criticized, leaving the thesis in doubt. This paper draws on Weber’s Law, a well-entrenched finding from psychophysics, to advance a new argument that perception is analog. This new argument is an adaptation of an argument that cognitive scientists have leveraged in support of the contention that primitive numerical representations are analog. But the argument here is extended to (...) the representation of non-numerical magnitudes, such as luminance and distance, and shown to apply to perception and not just cognition. The relevant sense of ‘analog’ is also clarified, and two powerful objections are addressed. Finally, the question whether perception’s analog vehicles are located in conscious experience is explored and related to a well-known controversy within psychophysics. (shrink)

Building on Christopher Peacocke’s account of analog perceptual contentand my own account of analog perceptual vehicles, I defend three claims: that theperception of magnitudes often has analog contents; that the perception of magni-tudes often has analog vehicles; and that the first claim is true in virtue of the second—that is, the analog vehicles help to ground the analog contents.

It is fairly well-known that certain hard computational problems (that is, 'difficult' problems for a digital processor to solve) can in fact be solved much more easily with an analog machine. This raises questions about the true nature of the distinction between analog and digital computation (if such a distinction exists). I try to analyze the source of the observed difference in terms of (1) expanding parallelism and (2) more generally, infinite-state Turing machines. The issue of discreteness vs (...) continuity will also be touched upon, although it is not so important for analyzing these particular problems. (shrink)

Newtonian and Machian aspects of the stationary gravitational field are brought into formal analogy with a stationary electromagnetic field. The electromagnetic vector potential equals (up to a factor) the timelike Killing vector field. The current density is given by the contraction of the Killing vector with the Ricci tensor. A coordinate-dependent split in electric and magnetic field vectors is given, and some results of classical electrodynamics are used to illustrate the analogy. In the linearized theory, the usual Maxwell equations are (...) obtained. The analogy also holds from the point of view of particle motion. The geodesic equation is brought into a special form that exhibits an analog to the Lorentz force. Two examples (which have played an important role in the theoretical discovery of Machian effects) are considered. (shrink)

Computationalism about the brain is the view that the brain literally performs computations. For the view to be interesting, we need an account of computation. The most well-developed account of computation is Turing Machine computation, the account provided by theoretical computer science which provides the basis for contemporary digital computers. Some have thought that, given the seemingly-close analogy between the all-or-nothing nature of neural spikes in brains and the binary nature of digital logic, neural computation could be a species of (...) digital computation. A few recent authors have offered arguments against this idea; here, I review recent findings in neuroscience that further cement the implausibility of this view. However, I argue that we can retain the view that the brain is a computer if we expand what we mean by “computation” to include analog computation. I articulate an account of analog computation as the manipulation of analog representations based on previous work on the difference between analog and non-analog representations, extending a view originally articulated in Shagrir :271–279, 2010). Given that analog computation constitutes a significant chapter in the history of computation, this revision of computationalism to include analog computation is not an ad hoc addition. Brains may well be computers, but of the analog kind, rather than the digital kind. (shrink)

Flanders will complete the migration from analog to digital terrestrial television by the end of 2008. Despite the cable dominated television landscape, the Flemish government is aiming at a smooth transition from analog to digital terrestrial television. Therefore, a multi-methodical study has been set up by order of the Flemish government to understand the specific features and needs of analog antenna viewers and their expectations for the analog switch-off. The study shows that there are three distinctive (...) types of analog antenna viewers. The results demonstrate that the antenna viewers are rather badly informed about the upcoming analog switch-off, which may lead to a negative attitude and may impede a smooth transition. Finally, antenna viewers seem to be rather conservative viewers: they wish to keep on watching the same television programs from the same channels. Moreover, digital terrestrial television is their preferred alternative. (shrink)

We live in an era characterized by technology as an integral part of the overall experiences. Non-hierarchic access to communication and virtual contacts in the metaverse, experienced as no less real than those in the brick-and-mortar world. The global health crisis has further highlighted the understanding that the integration of technology into our lives is inevitable, and when it comes to teaching and learning, the right use of technology can take teachers and learners to new, exciting places. The social distancing (...) regulations imposed worldwide provided educators with an opportunity to try out a variety of technological tools that enable surprising collaborations and access to information that encourages cognitive flexibility and a reexamination of our assumptions on knowledge, learning, teaching, human interaction, and space-time’s limitations. However, one great challenge within this ongoing transition concerns underprepared educators, feeling the pressure to make a successful shift while sustaining their educational inner compass regarding what constitutes adequate education. In this teacher’s self-study, I examined my teaching experience while teaching online. Informed by existing research, critical reflections, dialogue with a critical friend, a community of colleagues, and students’ artifacts, I inquire whether—and how—I can practice dialogical pedagogy while teaching online.

This article intends to establish a comparison between technical analog objects—which were the objects of the epoch when the French philosopher Gilbert Simondon elaborated his philosophical reflection—and digital devices that emerged in the last few decades of the 1900s. First, I define the main features of Simondon’s technical objects in order to understand what the necessary conditions are for there to be technical progress, which is based on what he called the process of concretization. Then, I analyze the relationship (...) between digital objects—as understood by Yuk Hui—and digital devices that take over from analog objects, without necessarily presenting continuity in an evolutionary process. Finally, I intend to expose the role that both analog objects and digital devices play as mediators with the world in a digital era, and to address the question of technical culture nowadays. (shrink)
