PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. Images (...) were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

This paper puts forth two reasons to hold that at least some mental entities are not physical entities. First argument: Some mental entities (namely, pains and other qualia) cannot possibly differ from how they seem to be, and since this cannot possibly be true of any non-mental entity, it follows that some mental entities are not physical. Second argument: It is necessarily on theoretical grounds, as opposed to strictly experiential grounds, that mental entities are identified with physical entities. Water is (...) legitimately believed to consist of microparticles of a certain kind because there is independent reason to believe that entities relevantly similar to such particles, supposing them to exist, are relevantly similar to water, so far as the latter can be directly observed. It is not, nor could it possibly be, on the basis of some directly observed concomitance between molecule-activity and water-activity that we believe the former to constitute the latter. It obviously isn't on the basis of any directly observed concomitance between brain-activity and mental-activity that the former is believed to mediate the latter. At the same time, there cannot possibly be any other legitimate basis for that belief. The reason for this is that nothing relevantly similar to mental activity can possibly be observed to accompany anything relevantly similar to brain activity. And the reason for the latter fact is that, even if brain-activity and mental-activity occur in the same physical space, they occur in different data-spaces: when you experience a pain, it is not given to you as occurring in the same spatial manifold as the falling of a stone or any other physical event. In general, mental events, whether or not they in fact have spatial coordinates, cannot possibly be observed (experienced) as having such coordinates, and for this reason they cannot be observed as having the same coordinates as brain-events. Thus, there can be no reason to grant the existence of the concomitances whose existence is needed to legitimate the bridge principles on the basis of which the mental could legitimately be identified with the physical. Note on the second argument: This argument doesn't show that the mental is non-physical; it shows only that there cannot possibly be any justification for the belief that the mental to be physical or, at any rate, that, if there is such a justification, it isn't comparable to the justification for the belief that water consists of molecules.

Male violence against women is at shocking levels in South Africa. According to Faul, ‘A woman is killed by an intimate partner every eight hours, a probable underestimate because no perpetrator is identified in 20 percent of killings’, whilst ‘More than 30 percent of girls have been raped by the time they are 18’. Reeva Steenkamp’s killing by her partner, Oscar Pistorius, came ‘the day before she planned to wear black in a “Black Friday” protest against the country’s excruciatingly high (...) number of rapes’. The purpose of this article is to reread a key biblical text regarding male violence against women in order to highlight how Jesus would want us to respond to such violence. The text is John 7:53–8:11. The NRSV: Catholic Edition entitles the story ‘The woman caught in adultery’. However, this title is problematic as it can lead to misleading readings of the text, as I will show, and so I have given it a different title, namely ‘The woman threatened with stoning’. (shrink)

This, the twenty-seventh volume in the annual series of publications by the American Society for Political and Legal Philosophy, features a number of distinguised contributors addressing the topic of criminal justice. Part I considers "The Moral and Metaphysical Sources of the Criminal Law," with contributions by Michael S. Moore, Lawrence Rosen, and Martin Shapiro. The four chapters in Part II all relate, more or less directly, to the issue of retribution, with papers by Hugo Adam Bedau, Michael Davis, (...) Jeffrie G. Murphy, and R. B. Brandt. In the following part, Dennis F. Thompson, Christopher D. Stone, and Susan Wolf deal with the special problem of criminal responsibility in government-one of great importance in modern society. The fourth and final part, echoing the topic of NOMOS XXIV, Ethics, Economics, and the Law , addresses the economic theory of crime. The section includes contributions by Alvin K. Klevorick, Richard A. Posner, Jules L. Coleman, and Stephen J. Schulhofer. A valuable bibiography on criminal justice by Andrew C. Blanar concludes this volume of NOMOS. (shrink)

The phenomenon of commitment is a cornerstone of human social life. Commitments make individuals' behavior predictable, thereby facilitating the planning and coordination of joint actions involving multiple agents. Moreover, commitments make people willing to rely upon each other, and thereby contribute to sustaining characteristically human social institutions such as jobs, money, government and marriage. However, it is not well understood how people identify and assess the level of their own and others' commitments. The Philosophy and Psychology of Commitment explores and (...) explains the philosophical and cognitive issues that underpin commitment. John Michael considers how commitments motivate us and their often implicit and tacit nature. To flesh out the philosophical framework of his argument he draws on experimental work with young children, adults and human-robot interaction within the context of joint action, considering the role of the emotions and whether very young children are capable of joint action. Providing an important account of the nature and operation of commitment, this book is essential reading for those working in philosophy of psychology, cognitive science, experimental philosophy, and social and developmental psychology. It will also be of interest to those working in emerging fields such as human-robot interaction and behavioural economics. (shrink)

The seminal ideas of the most influential modern art educator are presented here as he developed them, in edited transcripts of Viktor Lowenfeld's 1958 class lectures and discussions on art education and art therapy. The transcripts serves as explication of Lowenfeld's_ Creative and Mental Growth_, now going into a seventh edition—with posthumous collaborators since the author's death in 1960—translated into all the world's major languages. The experiential basis of Lowenfeld's ideas is revealed through the autobiographical and reflective quality of his (...) lectures and his Socratic dialogs with students. Both his vicarious experience, arising from his erudition, and his immediate experience, stemming from his sensitivity to everyday stimuli, are focused on the problem at hand. The result is a freshness and immediacy as though the author were speaking directly to the reader about mutual concerns. The book presents transcripts of 31 class sessions conducted by Lowenfeld on Art and the Child, Art and the Adolescent, and Art Education Therapy in the year after his election as "Art Educator of the Year" by national Art Education Association. The editor's introduction gives the highlights of Lowenfeld's life and work and the circumstances surrounding the recorded class meetings. The book concludes with a selected bibliography of the works of Viktor Lowenfeld. (shrink)

In recent years, several minimalist accounts of joint action have been offered (e.g. Tollefsen Philosophy of the Social Sciences 35:75–97, 2005; Sebanz et al. Journal of Experimental Psychology: Human Perception and Performance, 31(6): 234–1246, 2006; Vesper et al. Neural Networks 23 (8/9): 998–1003, 2010), which seek to address some of the shortcomings of classical accounts. Minimalist accounts seek to reduce the cognitive complexity demanded by classical accounts either by leaving out shared intentions or by characterizing them in a way that (...) does not demand common knowledge of complex, interconnected structures of intentions. Moreover, they propose models of the actual factors facilitating online coordination of movements. The present proposal aims to enrich a minimalist framework by showing how shared emotions can facilitate coordination without presupposing common knowledge of complex, interconnected structures of intentions. Shared emotions are defined for the purposes of this paper as affective states that fulfill two minimal criteria: (a) they are expressed (verbally or otherwise) by one person; and (b) the expression is perceived (consciously or unconsciously) by another person. Various ways in which the fulfillment of (a) and (b) can lead to effects that function as coordinating factors in joint action are distinguished and discussed. (shrink)

In this paper, I critically assess the thesis that the discovery of mirror neuron systems provides empirical support for the simulation theory of social cognition. This thesis can be analyzed into two claims: that MNSs are involved in understanding others’ intentions or emotions; and that the way in which they do so supports a simulationist viewpoint. I will be giving qualified support to both claims. Starting with, I will present theoretical and empirical points in support of the view that MNSs (...) play a substantial role and are perhaps neces¬sary although not sufficient for understanding at least some intentions or emo¬tions. Turning to, I will argue that the work on MNSs best supports a fairly weak version of ST, according to which social cognition involves simulation simply because conceptual thought in gen¬eral has a simulationist component. In elucidating this idea, I appeal to Law¬rence Barsalou’s embodied theory of concepts. Crucially, the term “simula¬tion” here refers not to simulations of a target agent’s experience, nor even spe¬cifically to one’s own experience in a similar counterfactual situation, but to simulations of experience in general - activating sensory, motor, proprioceptive, affective, and introspective representations that match representations one would have when perceiving, carrying out actions, experiencing emotions, etc. I then sketch an expanded simulationist framework for understanding the contribution of MNSs to social cognition. The ap¬peal to empirical work on MNSs in support of ST is therefore a two-edged sword; making this appeal persuasive requires us to modify our understanding of simulation to make it line up with the empirical work.

In recent years, developmental psychologists have increasingly been interested in various forms of prosocial behavior observed in infants and young children—in particular comforting, sharing, pointing to provide information, and spontaneous instrumental helping. We briefly review several models that have been proposed to explain the psychological mechanisms underpinning these behaviors. Focusing on spontaneous instrumental helping, we home in on models based upon what Paulus :77–81, 2014) has dubbed ‘goal-alignment’, i.e. the idea that the identification of an agent’s goal leads infants to (...) take up that goal as their own. We identify a problem with the most well-known model based upon this idea, namely the ‘goal contagion’ model. The problem arises from the way in which the model specifies the content of the goal which is identified and taken up. We then propose an alternative way of specifying the content of the goal, and use this as a starting point for articulating an alternative model based upon the idea of alignment, namely the ‘goal slippage’ model. By elucidating the difference between goal contagion and goal slippage, we contribute to the articulation of experimental criteria for assessing whether and when the mechanisms specified by these two models are at work.

In the current paper, we present and discuss a series of experiments in which we investigated people’s willingness to ascribe intentions, as well as blame and praise, to groups. The experiments draw upon the so-called “Knobe Effect”. Knobe [2003. “Intentional action and side effects in ordinary language.” Analysis 63: 190–194] found that the positiveness or negativeness of side-effects of actions influences people’s assessment of whether those side-effects were brought about intentionally, and also that people are more willing to assign blame (...) for negative side-effects of actions than they are to assign praise for positive side-effect of actions. Building upon this research, we found evidence that the positiveness or negativeness of side-effects of group actions influences people’s willingness to attribute intentions to groups, and that people are more willing to assign blame to groups for negative side-effects of actions than they are to assign praise to groups for positive side-effects of...

I argue that fictionalism is an unpromising alternative to realism in two important respects. First, fictionalism offers a less satisfactory modal semantics because the incorporated fictive operator is itself modal and its results differ significantly from realism. Second, fictionalism struggles to provide us with a satisfactory account of the ontological grounding of modal truth and finds itself in opposition to several influential accounts of fictional objects which I discuss. I conclude by suggesting that, given the fictionalist’s motivation, a more promising (...) avenue of research would be the older and currently unfashionable fictionalism espoused by Vaihinger (1935).

Michael-John Turp | : There is little consensus concerning the truth or reference conditions for evaluative terms such as “good” and “bad.” In his paper “Good and Evil,” Geach proposed that we distinguish between attributive and predicative uses of “good.” Foot, Thomson, Kraut, and others have put this distinction to use when discussing basic questions of value theory. In §§1-2, I outline Geach’s proposal and argue that attributive evaluation depends on a prior grasp of the kind of thing (...) that is evaluated, which is another way of saying a prior grasp of a thing’s nature. In §§3-4, I discuss the evaluation of artifacts, which provide the clearest examples of attributive evaluation. This allows me to address a series of problems apparently facing the idea of attributive goodness. In §5, I consider the neo-Aristotelian idea that we can extend attributive accounts of goodness to human lives, and I pay attention to Foot’s account of natural goodness. This leads me to consider the goodness of human life as a whole in §6. At this point. I depart from Geach’s approach and argue that questions of attributive goodness finally give rise to questions of predicative or absolute goodness. | : Il y a peu de consensus sur la vérité ou les conditions de référence pour les termes évaluatifs tels que « bon » et « mauvais ». Dans son article « Good and Evil », Geach a proposé de distinguer les usages attributif et prédicatif du « bon ». Foot, Thomson, Kraut et d’autres considèrent qu’il faut utiliser cette distinction lorsqu’il s’agit des questions fondamentales de la théorie de la valeur. Dans les parties 1-2, je décris ici la proposition de Geach et je prétends que l’évaluation attributive dépend d’une compréhension préalable du genre de chose qui est évaluée, ce qui est une autre façon de dire une compréhension préalable de la nature d’une chose. Dans les parties 3-4, je discute de l’évaluation des artefacts, qui fournissent les exemples les plus clairs d’évaluation attributive. Cela me permet d’illustrer une série de problèmes apparemment liés à l’idée de la bonté attributive. Dans la partie 5, je considère l’idée néo-aristotélicienne voulant que nous puissions étendre notre compréhension de la bonté attributive aux vies humaines, et je me penche sur l’idée de bonté naturelle selon Foot. Cela me conduit à considérer la bonté de la vie humaine comme un tout, dans la partie 6. De là, je m’éloigne de l’approche de Geach pour affirmer que les questions de bonté attributive suscitent finalement des questions de bonté prédicative ou absolue. (shrink)

A considerable body of research has documented the emergence of what appears to be instrumental helping behavior in early childhood. The current study tested the hypothesis that one basic psychological mechanism motivating this behavior is a preference for completing unfinished actions. To test this, a paradigm was implemented in which 2-year-olds (n = 34, 16 female/18 male, mostly White middle-class children) could continue an adult’s action when the adult no longer wanted to complete the action. The results showed that children (...) continued the adult’s actions more often when the goal had been abandoned than when it had been reached (OR = 2.37). This supports the hypothesis that apparent helping behavior in 2-year-olds is motivated by a preference for completing unfinished actions. (shrink)

In this paper, we evaluate the proposal that a central function of commitments within joint action is to reduce various kinds of uncertainty, and that this accounts for the prevalence of commitments in joint action. While this idea is prima facie attractive, we argue that it faces two serious problems. First, commitments can only reduce uncertainty if they are credible, and accounting for the credibility of commitments proves not to be straightforward. Second, there are many other ways in which uncertainty (...) is commonly reduced within joint actions, which raises the possibility that commitments may be superfluous. Nevertheless, we argue that the existence of these alternative uncertainty reduction processes does not make commitments superfluous after all but, rather, helps to explain how commitments may contribute in various ways to uncertainty reduction.

ABSTRACT In what sense is commitment essential to joint action, and do the participants in a joint action themselves perceive commitment as essential? Attempts to answer this question have so far been hampered by clashes of intuition. Perhaps this is because the intuitions in question have mostly been investigated using informal methods only. To explore this possibility, we adopted a more formal approach to testing intuitions about joint action, sampling naïve participants’ intuitions about experimentally controlled scenarios. This approach did reveal (...) patterns in participants’ responses which may hint at potential conceptual links between commitment and joint action. It did not however provide evidence to support the view that commitment is essential to joint action, at least not from the agents’ own perspective. We conclude that intuitions alone, even when drawn systematically from a large sample, may be a poor basis for theorizing about joint action. (shrink)

In this brief discussion, we explicate and evaluate Heyes and colleagues’ deflationary approach to interpreting apparent evidence of domain-specific processes for social percep- tion. We argue that the deflationary approach sheds important light on how functionally specific processes in social perception can be subserved at least in part by domain-general processes. On the other hand, we also argue that the fruitfulness of this approach has been unnecessarily hampered by a contrastive conception of the relationship between domain- general and domain-specific processes. (...) As an alternative, we propose a complementary conception: the identification of domain-general processes that are engaged in instances of social perception can play a positive, structuring role by adding additional constraints to be accounted for in modelling the domain-specific processes that are also involved in such instances.

In recent years, a number of theorists have developed approaches to social cognition that highlight the centrality of social interaction as opposed to mindreading (e.g. Gallagher and Zahavi 2008 ; Gallagher 2001 , 2007 , 2008 ; Hobson 2002 ; Reddy 2008 ; Hutto 2004 ; De Jaegher 2009 ; De Jaegher and Di Paolo 2007 ; Fuchs and De Jaegher 2009 ; De Jaegher et al. 2010 ). There are important differences among these approaches, as I will discuss, but (...) they are united by their commitment to the claim that various embodied and extended processes sustain social understanding and interaction in the absence of mindreading and thus make mindreading superfluous. In this paper, I consider various ways of articulating and defending this claim. I will argue that the options that have been offered either fail to present an alternative to mindreading or commit one to a radical enactivist position that I will give reasons for being skeptical about. I will then present an alternative and moderate version of interactionism, according to which the embodied and extended processes that interactionists emphasize actually complement mindreading and may even contribute as an input to mindreading.

Rivka Weinberg advances an error theory of ultimate meaning with three parts: (1) a conceptual analysis, (2) the claim that the extension of the concept is empty, and (3) a proposed fitting response, namely being very, very sad. Weinberg’s conceptual analysis of ultimate meaning involves two features that jointly make it metaphysically impossible, namely (i) the separateness of activities and valued ends, and (ii) the bounded nature of human lives. Both are open to serious challenges. We offer an internalist alternative (...) to (i) and a relational alternative to (ii). We then draw out implications for (2) and conclude with reasons to be cheerful about the prospects of a meaningful life. (shrink)

Gradually emerging from the so-called 'linguistic turn', philosophy in the second half of the twentieth century witnessed what we might follow P. M. S. Hacker in describing as a 'naturalistic turn'. This change of direction, an abandon­ment of traditional philosophical methods in favour of a scientific approach, or critics would say a scientistic approach, has met with widespread approval. In the first part of the paper I look to establish the centrality of the normative to the dis­cipline of epistemology. I (...) then turn to examine Quine's attempt to reduce norma­tive discourse to instrumental rationality, and the more fully developed accounts provided by Stich, Kornblith and Papineau. I argue that these accounts fail because they insist on a constitutive connection between desires and the ends of epistemic activity. I conclude with the suggestion that a more plausible position severs this connection, in favour of an objective, externalist account of ends and reasons. (shrink)

The 2011 tsunami had a devastating effect on the east coast of Japan. Particularly poignant were the century-old markers on hillsides warning against building anywhere below. Nevertheless, such wisdom from traditional knowledge was disregarded because of the perceived invulnerability of the modern. This paper attempts to garner such traditional empirical knowledge regarding the siting of towns and cities by considering the Chinese art/science of fengshui or dili, the original purpose of which was to site human habitation in the most favourable (...) places for long term survival. This knowledge is then used to consider the placement of cities created by modernity, those founded on and flourishing through the advent of globalisation, such as Hong Kong, Shanghai, St Petersburg, and Sydney.

This paper, based on a talk given at the Art Gallery of New South Wales, is presented as an example of philosophy done in an art gallery. Its subject is Tom Roberts’ painting Holiday Sketch at Coogee (1888), and as well as responding directly to the painting in the environment of the gallery, it draws on the author's memories of seeing that painting in other times and places. It draws on these personal experiences to relate Roberts’ painting to a controversial (...) idea laid out by art historian Heinrich Wölfflin, and to more recent conventionalist and resemblance theories of pictorial representation. It finishes by affirming one of Roberts’ important achievements: his discarding of inherited European ways of picture‐making, and his place among the first generation of non‐indigenous artists to represent the real colours of the Australian landscape.

In lieu of an abstract, here is a brief excerpt of the content:Romanticism and Coleridge’s Idea of HistoryMichael John Kooy*Romantic historiography is widely understood in methodological terms as a subjectively determined treatment of the human past, according to which historical knowledge is grounded in imaginative activity. That ambition was amply fulfilled in Scott’s historical novels, as Georg Lukacs once demonstrated. 1 Writing in broader terms, Hayden White characterized that whole creative enterprise as an “effort at palingenesis,” the striving to (...) recreate or relive the past in individual consciousness. 2In more recent years, as the approach to the period has become more historicist, criticism has begun to separate the historical and the aesthetic aspects of this romantic sensibility, usually emphasizing one at the expense of the other. The result has been a standoff in critical thinking about the way Romanticism represents the past. One side is occupied by some new historicists who claim to find a precedent for their own methodology among prominent figures of the period. Heyne, Wordsworth, and Keats, it turns out, not only were engaged actively in their own contemporary history, but they also demonstrated in their sophisticated evocation of the past the impossibility of overcoming historical difference by reference to natural law. 3 Arguments advanced on the other side of the controversy insist that the Romantics were not nearly such good historicists as supposed. In these accounts, often allied to post-structuralism, the aesthetic absolutism implicit in the high romantic argument is undiminished by the burgeoning historical consciousness in the period. Indeed, Romanticism’s aesthetic [End Page 717] retrieval of the past appears to be an instance of how subjectivity, rather than admit its own historicity, again asserts mastery over the object through its own self-will. 4Each of these accounts commands a considerable following, and a peace between them seems unlikely, indeed undesirable. On one matter they do agree, though, and that is in their distrust of Coleridge. His historiography—the notion that ideas make history and that the way to get at these ideas is aesthetically—is too idealist for today’s historicists and too monumentally subjective for the post-structuralists. I think both judgments are hasty. Coleridge, more than most contemporaries, reflected for many years upon the difficulties that arose in his own attempts to interpret historical knowledge (which appeared as a subjective, aesthetic construct) in systematic terms (as the reflection of natural order); and a good look at the record will show that his thought is not quite so anti-historical as some believe, and his subjective approach not nearly so absolutist.The goal of this essay is to rehabilitate Coleridge’s idea of history, considering what it tells us about Romanticism and how it foreshadows current debates about methodology. 5 More specifically, I want to show how in different contexts Coleridge treats, with varying degrees of success, history as an ideational field that is both created and then interpreted by an inquiring subject. First, at the literary and cultural level, history is conceived as the object of imaginative reconstruction, where subjectivity provisionally orders the mass of material according to an idea found nowhere within history itself. Here the anti-positivist bias of Coleridge’s idealist historiography dominates a project that is, both in orientation and achievement, not so much cognitive as aesthetic. Secondly, at the level of religion, history is conceived in mythic terms, the past being revealed only symbolically to the discerning inquirer who must interpret the Christian mythos as recorded in the inspired biblical account of the nation of Israel. Here it is the application of certain interpretive or hermeneutic strategies that determines success or failure. Finally, as a single idea, history is conceived as the process of humanity seeking consciousness of itself, and this Coleridge expresses in a narrative of universal proportions, beginning in apostasy and ending in grace. Here teleology dominates, but as Coleridge discovers, this providential [End Page 718] history is a story that cannot be fully told, thought, or even, it turns out, imagined. It can only be postulated as an idea of reason or, in religious terminology, held as an article of faith. In a curious return to aesthetics Coleridge argues that for the grand historical narrative, just as for art... (shrink)

In the current paper, we articulate a theory to explain the phenomenology of mental effort. The theory provides a working definition of mental effort, explains in what sense mental effort is a limited resource, and specifies the factors that determine whether or not mental effort is experienced as aversive. The core of our theory is the conjecture that the sense of effort is the output of a cost-benefit analysis. This cost-benefit analysis employs heuristics to weigh the current and anticipated costs (...) of mental effort for a particular activity against the anticipated benefits. This provides a basis for spelling out testable predictions to structure future research on the phenomenology of mental effort. (shrink)

We propose category theory, the mathematical theory of structure, as a vehicle for defining ontologies in an unambiguous language with analytical and constructive features. Specifically, we apply categorical logic and model theory, based upon viewing an ontology as a sub-category of a category of theories expressed in a formal logic. In addition to providing mathematical rigor, this approach has several advantages. It allows the incremental analysis of ontologies by basing them in an interconnected hierarchy of theories, with an operation on (...) the hierarchy that expresses the formation of complex theories from simple theories that express first principles. Another operation forms abstractions expressing the shared concepts in an array of theories. The use of categorical model theory makes possible the incremental analysis of possible worlds, or instances, for the theories, and the mapping of instances of a theory to instances of its more abstract parts. We describe the theoretical approach by applying it to the semantics of neural networks. (shrink)

The Cynic exhortation to live according to nature is far from transparent. I defend a traditional interpretation: to live in accordance with nature is to live in accordance with human nature, which is to live as a rational animal. After discussing methodological concerns, I consider the theriophilic proposal that the ideal Cynic lives like an animal. I marshal evidence against this view and in favor of the alternative of Cynics as rational animals. Finally, I anticipate and address the concern that (...) mine is an unduly idealized and Stoicized account. (shrink)
