There is a variety of epistemic roles to which photographs are better suited than non-photographic pictures. Photographs provide more compelling evidence of the existence of the scenes they depict than non-photographic pictures. They are also better sources of information about features of those scenes that are easily overlooked. This chapter examines several different attempts to explain the distinctive epistemic value of photographs, and argues that none is adequate. It then proposes an alternative explanation of their epistemic value. The chapter argues (...) that photographs play the epistemic roles they do because they are typically rich sources of depictively encoded information about the scenes they depict, and reliable depictive representations of those scenes. It then explains why photographs differ from non-photographic pictures in both respects. (shrink)

While scientific inquiry crucially relies on the extraction of patterns from data, we still have a far from perfect understanding of the metaphysics of patterns—and, in particular, of what makes a pattern real. In this paper we derive a criterion of real-patternhood from the notion of conditional Kolmogorov complexity. The resulting account belongs to the philosophical tradition, initiated by Dennett :27–51, 1991), that links real-patternhood to data compressibility, but is simpler and formally more perspicuous than other proposals previously defended in (...) the literature. It also successfully enforces a non-redundancy principle, suggested by Ladyman and Ross, that aims to exclude from real-patternhood those patterns that can be ignored without loss of information about the target dataset, and which their own account fails to enforce.

In this paper, I discuss the influential view that depiction, like language, depends on arbitrary conventions. I argue that this view, however it is elaborated, is false. Any adequate account of depiction must be consistent with the distinctive features of depiction. One such feature is depictive generativity. I argue that, to be consistent with depictive generativity, conventionalism must hold that depiction depends on conventions for the depiction of basic properties of a picture’s object. I then argue that two considerations jointly (...) preclude depiction from being governed by such conventions. Firstly, conventions must be salient to those who employ them. Secondly, those parts of pictures that depict basic properties of objects are not salient to the makers and interpreters of pictures. (shrink)

One of the most prominent ethical concerns regarding emerging neurotechnologies is mental privacy. This is the idea that we should have control over access to our neural data and to the information about our mental processes and states that can be obtained by analyzing it. A key issue is whether this information needs more stringent protection than other kinds of personal information. I will articulate and support the view, underlying recent regulatory frameworks, that mental privacy requires a special treatment because (...) of its relation to relevant aspects of personal identity. It has been suggested that this approach could be supported by the idea that mental privacy constitutes a fundamental psychological dimension of privacy. The connection between this psychological view of privacy and identity can be traced back to Irwin Altman’s idea that privacy is an interpersonal boundary regulation process. However, it is not clear whether this notion of privacy can be associated with a conception of identity that is relevant in contemporary neuroethics. I will suggest that the narrative and relational approach to identity, a prominent view in recent ethical discussions of neurotechnology, lines up with key aspects of Altman’s proposal. I suggest that if mental privacy is an essential component of identity, the latter could be affected by technological mind-reading. (shrink)

The genre to which an artwork belongs affects how it is to be interpreted and evaluated. An account of genre and of the criteria for genre membership should explain these interpretative and evaluative effects. Contrary to conceptions of genres as categories distinguished by the features of the works that belong to them, I argue that these effects are to be explained by conceiving of genres as categories distinguished by certain of the purposes that the works belonging to them are intended (...) to serve.

In this paper, I provide a descriptive definition of art that is able to accommodate the existence of bad art, while illuminating the value of good art. This, I argue, is something that existing definitions of art fail to do. I approach this task by providing an account according to which what makes something an artwork is the institutional process by which it is made. I argue that Searle’s account of institutions and institutional facts shows that the existence of all (...) institutions is due to their being perceived by their participants to perform some humanly valuable function. I then identify the functions to which the existence of art institutions is due. I then use these functions to provide a reductive institutional definition of art. Finally, in section seven, I examine the account’s consequences for the value of good art. (shrink)

It is generally recognised that an adequate resemblance-based account of depiction must specify some standard of correctness which explains how a picture’s content differs from the content we would attribute to it purely on the basis of resemblance. For example, an adequate standard should explain why stick figure drawings do not depict emaciated beings with gargantuan heads. Most attempts to specify a standard of correctness appeal to the intentions of the picture’s maker. However, I argue that the most detailed such (...) attempt to date is incomplete. I argue that an adequate standard can be given only if one construes a picture’s content as being pictorially implicated, in a way analogous to that in which Grice explains an utterance’s meaning as being conversationally implicated. I propose a theory of pictorial implicature and use it as the basis for an intention-based standard of correctness. I show how this standard is able to explain both the ways in which the content of pictures differs from the content we would attribute to them solely on the basis of resemblance, and how we are able to apply an intention-based standard of correctness even though we lack any independent knowledge of the intentions of pictures’ makers.

The paper introduces a special issue of the journal Philosophical Problems in Science (ZFN) on the topic of the nature and norms of scientific explanation.

Given the irrationality and failures of human behaviour in the face of ecocide, the majority of humankind appears either unable or unwilling to change self-destructive ways of life. Rejecting common accounts, the author suggests that the reasons for our stubborn resistance to change go well beyond cognitive dissonance or any standard political and economic explanations. Nor is the answer to be found in human history alone. The driving forces underlying that resistance, the author argues, originate far back in evolutionary time (...) to the impulses governing all sentient creatures. -/- NB: The copy of this article is the final, pre-production version of the article published in the Architectural Research Quarterly.

I defend Christopher Peacocke's and Robert Hopkins's experienced resemblance accounts of depiction against criticisms put forward by Gavin McIntosh in a recent article in this journal. I argue that, while there may be reasons for rejecting Peacocke's and Hopkins's accounts, McIntosh fails to provide any.

An adequate account of the nature of genre and of the criteria for genre membership is essential to understanding the nature of the various categories into which comics can be classified. Because they fail adequately to distinguish genre categories from other ways of categorizing works, including categorizations according to medium or according to style, previous accounts of genre fail to illuminate the nature of comics categories. I argue that genres are sets of conventions that have developed as means of addressing (...) particular interpretative and/or evaluative concerns, and have a history of co‐instantiation within a community, such that a work’s belonging to some genre generates interpretative and evaluative expectations among the members of that community. Genres are distinct from styles in consisting of conventions, and are distinct from media both in consisting of conventions and in generating interpretative and evaluative expectations. (shrink)

In this paper, I discuss the account of depiction proposed by Robert Hopkins in his book Picture, Image and Experience. I first briefly summarise Hopkins’s account, according to which we experience depictions as resembling their objects in respect of outline shape. I then ask whether Hopkins’s account can perform the explanatory tasks required of an adequate account of depiction. I argue that there are at least two reasons for which Hopkins’s account of depiction is inadequate. Firstly, the notion of outline (...) shape, as Hopkins presents it, is inconsistent. Moreover, I argue that, while a consistent construal of outline shape is possible, Hopkins’s account becomes indistinguishable from previous accounts of depiction under any such construal. Second, I argue that, however it is construed, the notion of outline shape is unable to explain one of the central features which Hopkins himself insists any successful account of depiction must explain.

In his wide-ranging study of architecture and cultural evolution, Chris Abel argues that, despite progress in sustainable development and design, resistance to changing personal and social identities shaped by a technology-based and energy-hungry culture is impeding efforts to avert drastic climate change. The book traces the roots of that culture to the coevolution of Homo sapiens and technology, from the first use of tools as artificial extensions of the human body to the motorized cities spreading around the world, whose (...) uncontrolled effects are fast changing the planet itself. Advancing a new concept of the meme, called the 'technical meme', as the primary agent of cognitive extension and technical embodiment, Abel proposes a theory of the 'extended self' as a complex and diffuse outcome of that coevolution. Challenging conventional ideas of the self as a separate and autonomous being, the extended self, he explains, encompasses material and spatial as well as psychological and social elements, including the built environment and artifacts, and now reaches out into the virtual world of cyberspace. Drawing upon research into extended cognition and embodied minds from philosophy, psychology and the neurosciences, the book presents a new approach to environmental and cultural studies. N.B. This book was the winner of the International Committee of Architectural Critics 2017 Bruno Zevi Book Award by unanimous decision of the international jury. (shrink)

In this incisive study of the biological and cultural origins of the human self, the author challenges readers to re-think ideas about the self and consciousness as being exclusive to humans. In their place, he expounds a metatheoretical approach to the self as a purposeful system of extended cognition common to animal life: the invisible medium maintaining mind, body and environment as an integrated 'field of being'. Supported by recent research in evolutionary and developmental studies together with related discoveries in (...) animal behavior and the neurosciences, the author examines the factors that have shaped the evolution of the animal self across widely different species and times, through to the modern, technologically enmeshed human self; the differences between which are presented as relations of degree rather than absolute differences. Much like our primitive ancestors, he contends, routine human behaviour is governed more by unconscious instinct than self-conscious rationality, and is generally resistant to any major changes in customary habits of life, until compelled in time to do so. However, in extreme and rapidly evolving circumstances, as with climate change, tardy responses may become so detached from reality as to constitute an actual threat to survival. (shrink)

Expanding his collected essays on architectural theory and criticism, Chris Abel pursues his explorations across disciplinary and regional boundaries in search of a deeper understanding of architecture in the evolution of human culture and identity formation. From his earliest writings predicting the computer-based revolution in customised architectural production, through his novel studies on 'tacit knowing' in design or hybridisation in regional and colonial architecture, to his radical theory of the 'extended self', Abel has been a consistently fresh and (...) provocative thinker, contesting both conventions and intellectual fashions. This revised third edition includes a new introduction and six additional chapters by the author covering a broad range of related topics, up to recent concerns with genetic design methods and virtual selves. Together with the former essays, the book presents a unique global perspective on the changing cultural issues and technologies shaping human identities and the built environment in diverse parts of the world, both East and West (from the book cover).

Exactly how do the sign/symbol/token systems of endo- and exo-biosemiosis differ from those of cognitive semiosis? Do the biological messages that integrate metabolism have conceptual meaning? Semantic information has two subsets: Descriptive and Prescriptive. Prescriptive information instructs or directly produces nontrivial function. In cognitive semiosis, prescriptive information requires anticipation and “choice with intent” at bona fide decision nodes. Prescriptive information either tells us what choices to make, or it is a recordation of wise choices already made. Symbol systems allow recordation (...) of deliberate choices and the transmission of linear digital prescriptive information. Formal symbol selection can be instantiated into physicality using physical symbol vehicles (tokens). Material symbol systems (MSS) formally assign representational meaning to physical objects. Even verbal semiosis instantiates meaning into physical sound waves using an MSS. Formal function can also be incorporated into physicality through the use of dynamically-inert (dynamically-incoherent or -decoupled) configurable switch-settings in conceptual circuits. This paper examines the degree to which biosemiosis conforms to the essential formal criteria of prescriptive semiosis and cybernetic management. (shrink)

This paper concerns the conditions under which realism is an artistic merit in perceptual narratives, and its consequences for the practice of non-traditional casting. Perceptual narratives are narrative representations that perceptually represent at least some of their contents, and include works of film, television, theatre and opera. On certain construals of the conditions under which realism is an artistic merit in such works, non-traditional casting, however morally merited, is often artistically flawed. I defend an alternative view of the conditions under (...) which realism is an artistic merit in perceptual narratives. I identify the two forms of realism at issue in debates about the artistic merits of non-traditional casting, and identify the artistic norms that determine the conditions under which each constitutes an artistic merit. I argue that, independently of the relation between moral merits and artistic merits, non-traditional casting violates these norms less often than is sometimes assumed. Moreover, in certain circumstances, non-traditional casting affects realism in artistically meritorious ways. I conclude by considering the implications of my view for the practice of whitewashing.

This updated essay expands on the author's analysis of the complex social and psychological reasons for the inadequate response to the climate emergency. Recent reports by climate scientists quoted in the article suggest that the pace of climate change has already reached the point of irreversibility, triggering multiple tipping points with catastrophic implications for the future of life on this planet. Yet climate change denial, which as the author explains, takes many forms itself, both aggressive and passive, remains common at (...) all levels of human society, hindering effective action. Nevertheless, citing the growing number of legal cases being brought against both fossil fuel industries and state governments for not taking sufficient and verifiable measures for dealing with the crisis, the author finds positive signs that justice may be finally catching up with the culpable parties in both sectors.

A new strategy for moving forward in the characterization of the Global Neuronal Workspace (GNW) is proposed. According to Dehaene, Changeux and colleagues, broadcasting is the main function of the GNW. However, the dynamic network properties described by recent graph-theoretic GNW models are consistent with many large-scale communication processes that are different from broadcasting. We propose to apply a different graph-theoretic approach, originally developed for optimizing information dissemination in communication networks, which can be used to identify the pattern of frequency (...) and phase-specific directed functional connections that the GNW would exhibit only if it were a broadcasting network.

In the present article, we attempt to elucidate the conceptual rela- tionship between censorship and emotional development. We employ a framework from emotion regulation studies in order to clarify how censorship works and to ex- plain why it cannot affect emotional development in the same way as the remaining types of emotional regulation. Nevertheless, we argue that, by focusing on Plato’s ac- count of censorship, and specifically of its sociocultural function, one can find that it is not a useless device (...) for emotional development. Censorship affects relevant variables in the dynamics of contraposed emotional processes that compete for dominance. (shrink)

Attacks on migrant and refugee entrepreneurs and their properties by South African rivals and ordinary citizens have become a common phenomenon throughout the country, including the city of Cape Town. Business robberies often result in deaths or serious injuries. The Somali Community Board has noted that over 400 Somali refugees, many of them informal traders, were murdered in South Africa between early 2002 and mid-2010. The police are frequently accused by migrants of fomenting or turning a blind eye to xenophobic (...) attacks on their businesses. Meanwhile, the government refuses to acknowledge the existence of xenophobia or the xenophobic rhetoric in many of these attacks, claiming instead that they are simply the actions of criminal elements. Photographs published in the media of the looting of migrant stores do not tend to feature hardened criminals, but ordinary citizens including children in school uniform. -/- Migrant businesses are portrayed by officials, citizens and the media as having a negative impact on the South African economy and undermining the livelihoods of South Africans. The prevalence of such perceptions helps to explain growing xenophobic sentiment against migrants and refugees. Contrary to these popular perceptions, an emerging literature on migrant entrepreneurship is beginning to demonstrate the positive economic contributions of migrants and refugees to the country. This report examines the nature of informal migrant and refugee entrepreneurship in Cape Town and whether or not the negative stereotypes have any validity. It also seeks to examine what economic contributions migrants and refugees make to the local economy. -/- The report is based on the research conducted by the Growing Informal Cities project, a partnership between SAMP/IMRC, the African Centre for Cities at the University of Cape Town, the Gauteng City-Region Observatory (GCRO) and Eduardo Mondlane University in Maputo. A questionnaire was administered to a sample of 518 migrant owners of microenterprises, which had to meet three basic criteria for inclusion: (a) owned by a non-South African; (b) in operation for at least two years; and (c) unregistered with the South African Revenue Services (SARS). Although migrant entrepreneurs are located in most areas of the city, certain areas have particular concentrations of migrant-owned businesses. "e questionnaires were administered in four such areas: Imizamo Yethu, Philippi, Bellville, and Cape Town CBD. Thirty in-depth interviews were also conducted with selected owners of informal micro-enterprises. Two focus group discussions were held in the Cape Town CBD and Philippi respectively. Fifteen key informant interviews were held with various stakeholders in Cape Town to understand the operation and constraints faced by migrants operating in the city’s informal economy. -/- The major findings of the personal profile of the migrant and refugee entrepreneurs were as follows: -/- • The entrepreneurs came from over 20 different countries of which Zimbabwe, Somalia, the Democratic Republic of the Congo (DRC), Nigeria, Malawi, Ethiopia and Cameroon were the most prominent. Just over a third were from other countries in the SADC. The prominence of Zimbabwean entrepreneurs in the Cape Town informal economy is not surprising, given the events in that country over the past decade and a half and resultant mass migration to South Africa. A total of 57% of the entrepreneurs were from other African countries, especially the DRC, Somalia, Nigeria and Ethiopia. "e majority of migrants from these countries (except Nigeria) came to South Africa as refugees. -/- • A third of the entrepreneurs had refugee permits. Of these, nearly 60% came from only three countries: the DRC, Ethiopia and Somalia. A further 31% held asylum-seeker permits. Of these, 32% were Zimbabwean while another 30% came from DRC, Ethiopia and Somalia. Nearly 12% had permanent residence permits while 8% were holders of work permits. Only 7% of the respondents indicated that they did not have official documentation to stay in South Africa. Thus, the majority of migrant entrepreneurs have forced migrants who are entitled to human rights protection under international and South African refugee law. • Very few of the entrepreneurs entered South Africa before 1994. Only 8% arrived in the immediate post-apartheid years. While another 20% came in the period 2000to 2004, the vast majority (70%) came during the last decade. As many as 44% arrived between 2005 and 2009 and a further 27% thereafter. Migration from Zimbabwe, in particular, escalated between 2005 and 2009 as the country plunged deeper into crisis. • Despite the perception that unemployment at home is a driver of migration to South Africa, only 14% of the entrepreneurs were unemployed immediately before leaving for South Africa. Another 19% were students. Twenty-six percent were working in the informal economy in their home countries. -/- .......INCOMPLETE..... (shrink)

This book has three principle aims: to show that neither vision nor mental imagery involves the creation or inspection of picture-like mental representations; to defend the claim that our visual processes are, in significant part, cognitively impenetrable; and to develop a theory of “visual indexes”. In what follows, I assess Pylyshyn’s success in realising each of these aims in turn. I focus primarily on his arguments against “picture theories” of vision and mental imagery, to which approximately half the book is (...) devoted. I argue that Pylyshyn adopts an unnecessarily restricted interpretation of what it would be for mental representations to be picture-like, and that this leads him prematurely to reject the possibility of explaining the introspective evidence concerning the nature of mental imagery.

Review of: Abel, C. (2014). The extended self: Architecture, memes and minds. Manchester University Press.

This essay proposes to interpret the significance of the so-called immigration crisis in the light of the ancient story of Cain and Abel. Much more than a mere conflict between brothers, this essay will argue that the story of Cain and Abel presents two archetypal ways of dwelling in the world: the sedentary and the nomadic. As such, the story sheds a shocking new light on our present crisis, deeply problematizing the sedentary and revealing in an amazing tour (...) de force, the hidden potentialities of the nomadic and the powerful rejuvenating force that comes with its inclusion and welcoming in the sedentary landscape that characterizes our Western societies.

This article aims to investigate the extent to which Abel’s insertion in the debate on scepticism and naturalism in the Anglophone philosophical tradition, especially in the historical Strawson-Stroud debate on the success of transcendental arguments in response to the sceptical challenge, allows the creation of a conceptual scheme which refuses both the conventionalist and the naturalist position in regard to our conceptual schemas, while at the same time seeking to differentiate itself from the apriorism of the Kantian tradition. Although (...) I acknowledge that interpretationism offers a new solution to the issues involved in this debate, I argue that this solution is unable to deliver everything it promises. This new conceptual space is not determined enough to pacify scepticism. I conclude by suggesting that the attempt to reconcile Nietzsche and Wittgenstein introduces instability in Abel’s interpretation. The reformist impulse of Nietzsche’s philosophy rests on the results of a preliminary naturalistic stage (genealogical inquiry) which neither Wittgenstein nor Abel seems willing to incorporate into their philosophies.

The aim of this paper is to show that the French philosopher and historian of science Abel Rey played a more influential role in the formative phase of the Vienna Circle than hitherto supposed. On the whole, it will be argued that Rey's contribution had political impact. His interpretation of "modern physics" in 1907 in the face of the alleged "bankruptcy of science" should be appreciated as a masterpiece of applied enlightenment thought. As such, it was especially paradigmatic for (...) Philipp Frank's "positivist" defense of the theory of relativity and quantum mechanics against the irrationalist tendencies of the 1920s and 1930s.

This paper argues that, in its pre-Biblical version (pre-J), the Cain and Abel story principally dealt with tensions distinctive for dry-farming families identifying the social structure as their main cause. The social structure was problematic because it involved two important imbalances, one between the spouses and one between the children. Pre-J offers a novel solution to problems caused by these interfamilial imbalances: rather than accepting their pre-established social roles, people should develop a merit-based social structure. This is why Yahweh (...) says that acceptance and honour are in doing what is right. Focusing on a pre-J narrative in this way and situating the story within the broader motive of sibling rivalry, solve three puzzles: Yahweh’s preference (God challenges unjust social institutions), Cain’s reactions (he is angry because his expectations were unmet and depressed because he thought that this was his failure), and Yahweh’s final forgiveness to Cain (the conflict was not due to Cain’s wicked character).

Each of these books offers a richly developed and nuanced account of the nature of fiction. And each poses major challenges to a view about which there is a near-consensus. Catharine Abell draws on a theory of the institutions of fiction to advance a systematic re-envisioning of the metaphysics and epistemology of the contents of stories. Gregory Currie argues that fiction’s relationship to the imagination, and the way stories communicate their contents to readers, seriously undermine fiction’s cognitive values.

This study is a theoretical work in the field of sociology of religion which aims to explain the origin of the act of sin and the fundamental motives of crime and deviation tendencies in this context, from Adam’s story in the Qur'an, the main source of Islam. Sin is regarded as a negative act in religious-cultural sense where one struggles for life and tries to protect itself. Though a direct correlation cannot be established with belief values, the sense of sin (...) can be effective in shaping our everyday life and controlling our behavior. Adam’s story is worthy of examination in this context as it carries the qualification of being a religious text that allows us to study the nature of sin. This is based on the Qur'anic text which we think is the simplest form of expression. Adam and Eve, Satan, Abel and Cain are the actors of this story and prototypes helping us to analyze the nature of sin. In this sense, sin acts in the form of various crimes and deviance behaviors as the result of man's eternity of property, power and status struggle in the person of these prototypes. Some theories which have been put forward about crimes and deviations can give a certain explanation on the subject. Also there is the possibility of giving more comprehensive factual explanations about the act of sin which contains a great deal of crime and deviant behavior, moving from the story of Adam.

In ‘Location and Perdurance’ (2010), I argued that there are no compelling mereological or sortal grounds requiring the perdurantist to distinguish the molecule Abel from the atom Abel in Gilmore’s original case (2007). The remaining issue Gilmore originally raised concerned the ‘mass history’ of Adam and Abel, the distribution of ‘their’ mass over spacetime. My response to this issue was to admit that mass histories needed to be relativised to a way of partitioning the location of Adam/ (...) class='Hi'>Abel, but that did not amount to relativising any fundamental natural intrinsic properties—the latter are all had unrelativised, and (so most perdurantists would say).

Pierre Duhem gilt ais einer der wichtigsten Reprüsentanten der franzosischen Wissenschaftsphilosophie um 1900. Seine Konzeption physikalischer Theorien wird üblicherweise ais moderne Umsetzung des antiken – proto-positivistischen – Programms der „Rettung der Phänomene‟ angesehen.

Im vorliegenden Beitrag wird dargelegt, dass Duhems philosophischer Zeitgenosse Abel Rey eine zentrale Rolle in diesem Zusammenhang spielte.

The final section addresses different forms of knowledge (...) about the emotions conveyed by Unamuno’s fictional works. (shrink)

Psychology considered as a natural science began as Aristotelian "physics" or "natural philosophy" of the soul. C. Wolff placed psychology under metaphysics, coordinate with cosmology. Scottish thinkers placed it within moral philosophy, but distinguished its "physical" laws from properly moral laws (for guiding conduct). Several Germans sought to establish an autonomous empirical psychology as a branch of natural science. British and French visual theorists developed mathematically precise theories of size and distance perception; they created instruments to test these theories and (...) to measure visual phenomena such as the duration of visual impressions. These investigators typically were dualists who included mental phenomena within nature. (shrink)
