In the vertex pursuit game of cops and robbers on finite graphs, the cop has a winning strategy if and only if the graph admits a dominating order. Such graphs are called constructible in the graph theory literature. This equivalence breaks down for infinite graphs, and variants of the game have been proposed to reestablish partial connections between constructibility and being cop-win. We answer an open question of Lehner about one of these variants by giving examples of weak cop-win graphs (...) which are not constructible. We show that the index set of computable constructible graphs is Π11 hard and the index set of computable constructible locally finite graphs is Π40 hard. Finally, we give an example of a computable constructible graph for which every dominating order computes 0″. (shrink)

In forming the international regime on climate change, commodification of the atmosphere has become the primary mechanism around which policy formulation is being organized. This has been an outcome of the dominance of anthropocentric and ethnocentric values in the discourse represented by the negotiations around the Framework Convention on Climate Change. Environmentalism offers an alternative value system from which a critique of the emerging global climate change management regime can be undertaken. This critique makes clear both the inadequacy of economic (...) approaches based on commodification of the atmosphere to protect the global environment and the need to include a variety of actors, values, and approaches in the climate change policy debate.

At the turn of the 21st century, Susan Leigh Anderson and Michael Anderson conceived and introduced the Machine Ethics research program, that aimed to highlight the requirements under which autonomous artificial intelligence systems could demonstrate ethical behavior guided by moral values, and at the same time to show that these values, as well as ethics in general, can be representable and computable. Today, the interaction between humans and AI entities is already part of our everyday lives; in the near (...) future it is expected to play a key role in scientific research, medical practice, public administration, education and other fields of civic life. In view of this, the debate over the ethical behavior of machines is more crucial than ever and the search for answers, directions and regulations is imperative at an academic, institutional as well as at a technical level. Our discussion with the two inspirers and originators of Machine Ethics highlights the epistemological, metaphysical and ethical questions arising by this project, as well as the realistic and pragmatic demands that dominate artificial intelligence and robotics research programs. Most of all, however, it sheds light upon the contribution of Susan and Michael Anderson regarding the introduction and undertaking of a main objective related to the creation of ethical autonomous agents, that will not be based on the “imperfect” patterns of human behavior, or on preloaded hierarchical laws and human-centric values.

The Oxford Handbook of Comparative Political Theory provides an entry point into this burgeoning field by both synthesizing and challenging the terms that motivate it. The handbook demonstrates how mainstream political theory can and must be enriched through attention to genuinely global, rather than parochially Euro-American, contributions to political thinking. Entries emphasize exploration of substantive questions about political life-ranging from domination to political economy to the politics of knowledge-in a range of global contexts, with attention to whether and how those (...) questions may be shared, contested, or reformulated across differences of time, space, and experience. They connect comparative political theory to cognate disciplines including postcolonial theory, area studies, and comparative politics. Creative organizational tools such as tags and keywords aid in navigation of the handbook to help readers trace disruptions, thematic connections, contrasts, and geographic affinities across entries.

This paper treats two problem cases in decision theory, the Newcomb problem and Reed Richter''s Button III. Although I argue that, contrary to Richter, the latter case does not constitute a genuine counterexample to a standard general proposition of (causal) decision theory, I agree with and undertake to amplify his solution to the decision problem in Button III. I then apply the conclusions and distinctions in the foregoing treatment of Button III to the Newcomb problem and argue that a familiar (...) version of the dominance argument for taking both boxes runs afoul of plausible general constraints on rational agency. The underlying theme of the paper is that basic considerations of epistemic coherence play an important role in dealing with problem cases in decision theory. (shrink)

The vast majority of schools in Canada are dominated by unsafe spaces and experiences for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth 1 who continue to experience higher rates of suicide, depression, isolation, harassment/bullying, and self-harm compared to their straight peers2. Gay/Straight Alliances (GSAs) and other LGBTQ-inclusive groups exist in schools with the goal of mitigating and working against homophobia. Most often in Ontario (Canada), straight teachers lead these groups3. Because of the pervasive role straight teachers play in GSAs (...) and other anti-homophobia initiatives in schools, there is a practical need to analyze the role and experiences of straight teacher ally activists working with LGBTQ students and the overall effectiveness of anti-homophobia efforts under their purview. Here, I explore the efficacy of straight teacher allies, the importance of understanding straight privilege, and the significance of radical heterosexuality for straight people doing LGBTQ activism. Relying on queer theory and decolonizing/Indigenous queer theory, I argue that it is necessary for straight teachers to acknowledge their straight privilege in order to challenge homophobia’s companions: heterosexism and heteronormativity. In addressing the latter two covert forms of oppression in schools, teachers and students could shift into deeper, more effective resistance measures. (shrink)

Reuven Leigh provides the first in-depth introduction to the pioneering philosophy of Rabbi Shalom Schneersohn. Bringing him into dialogue with key continental philosophers Emmanuel Levinas, Jacques Derrida and Julia Kristeva, this book reveals how Schneersohn's views anticipated many prominent themes in 20th-century thought. Shalom Schneersohn (1860-1920) was the fifth Rebbe of the Habad-Lubavitch dynasty. He was a traditional, kabbalistic thinker and yet, beyond mysticism, he wrote extensively on speech, gender and the body. So why is he not better known? (...) Leigh begins by uncovering and contesting numerous scholarly assumptions that have operated to exclude traditional rabbinic thinkers from contemporary philosophical debates. Seeking to correct this, this book offers a close reading of Schneersohn's 1898 discourses. With the disruption of traditional binary structures being the dominant theme pervading Schneersohn's work, Leigh challenges Levinas' controversial ideas on the feminine. Examining Schneersohn on language, too, he highlights how Derridean deconstruction involves a more positive approach to presence that was already anticipated in the writings of Schneersohn. And from the disruption of the hierarchy of signification to the semiotic aspect of language and the maternal body, this book demonstrates how Schneersohn foreshadows a number of Kristeva's central philosophical concerns. A wide-ranging and inclusive volume, The Philosophy of Rabbi Shalom Schneersohn demonstrates not only how forward-thinking Schneersohn's ideas were a century ago, but how relevant they still are today.

Examining the Danish poultry industry in a time of rising outbreaks of infectious disease (the so-called ‘pandemic era’) including avian influenza, this study documents the often-unseen harms resulting from current dominant forms of response. Inspired by multispecies studies and ethnography, we pay attention to entangled human and more-than-human worlds. Specifically, we document the multifarious ways in which responses to worsening avian influenza alter the everyday lives of birds in production, their farmers, and public veterinarians. We also show how such changes (...) are distributed in ways that further slant the playing field against smaller scale and organic poultry production, under the hegemony of globalized capitalist agriculture. Throughout, we shed light on the analytical purchase of two key concepts in feminist scholarship and science and technology studies respectively: care and repair. While understood as integral to human and more-than-human wellbeing, care’s tendency to summon pleasant associations is challenged by the reality of embodied care practices in complex and compromised socio-ecological contexts. Repair has been wielded conceptually to interrogate activities that stabilize systems at risk, while largely ignoring or even exacerbating the drivers of instability. Mobilized together, we can better understand how hegemonic logics delimit possibilities for care, but also the limits and limitations of dominant response repertoires. Finally, we illuminate farming practices of care beyond repair, which may help chart alternatives for Danish agriculture within, and perhaps beyond, the pandemic era. (shrink)

Last year I published a short article urging bioethicists to carefully examine the question of what ought to constitute the canonical issues topics and questions driving research and teaching in bioethics. Why some subjects dominate the field whereas other topics are regarded as matters for scholars in other disciplines is a question that has intrigued me for nearly a decade. How are the boundaries of bioethics established? What factors influence research agendas and the creation of bioethics curricula? How do funding (...) agencies, editors, and leading scholars shape the field of bioethics? These questions are increasingly receiving scrutiny from Charles Bosk, Raymond De Vries, and other researchers as they explore the sociology of bioethics and the “construction” of the “ethical enterprise.".

While universal healthcare provisions are the global norm rather than the exception, the United States exists in the latter category. The paradox remains that while the right to health is both increasingly implemented and recognized on a global scale, the United States seems to run farther away from the arguments and global examples that might pave its way. I suggest that an understanding of the imposition of healthcare as “coercive,” and hence as an impingement on individual agency, activates its criticism (...) as an inhibition of freedom that in turn motivates the libertarianism at the heart of the dominant, market‐based approach to health insurance provisions. At least one of the underlying assumptions of this view is that universal healthcare would impose or impinge on individual rights, and that such an impingement is a violation of autonomy. In this article, I aim to challenge this assumption by suggesting that the pitting of individual health rights against collective burdens stems in part from a related assumption of general health or welfare on the part of the collective: that disability and debility alike are anomalies or anomalous to the general health of the population. In other words, it will be my contention that individual health rights are only at odds with “collective rights” when the collective is perceived to be able‐bodied. (shrink)

Development scholars and practitioners are promoting food security, food sovereignty, and the localization of food systems to prepare for the projected negative impacts of climate change. The implementation of biodiverse homegardens is often seen as a way not only to localize food production but also as a strategy in alignment with a food sovereignty agenda. While much scholarship has characterized and critiqued food security and sovereignty conceptualizations, relatively little research has examined people’s lived experiences in order to test how such (...) theoretical visions play out on the ground in farming communities. Based on a case study of four coffee cooperatives in northern Nicaragua, we examine a non-governmental organization (NGO)-supported project promoting food security and sovereignty through development of homegardens. We ask: To what extent are homegardens an effective strategy to reach food sovereignty? And, why may farmers be resistant to changing their food production and consumption strategies to embrace biodiverse homegardens when they improve food security? We discuss characteristics of agroecological homegardens, the distinctions between food security, food sovereignty and dominant discourses of development, the history of food sovereignty in Nicaragua, and farmer perspectives on homegarden implementation. Despite historic critiques, NGOs are poised to facilitate the transformation of food and agricultural development by employing counter development strategies, a necessary step if homegardens are to be successful in the long term. To conclude, we propose some strategies NGOs and communities might pursue to move forward with homegardens as a food sovereignty strategy. This research suggests that a food sovereignty approach still rooted in mainstream development models faces significant obstacles to moving beyond food security and into a farmer-led food sovereignty agenda.

As rapid economic development brings increasing uncertainty in East Asia, interest in a new version of republicanism, termed iscalled neo-Roman republicanism, is growing across the region. Conceptualized as liberty as non-domination, this new form of republicanism has inspired not only Western but also East Asian political theorists. However, neo-Roman republican ideas in Northeast Asian countries continue to face serious conceptual and political challenges, which scholarly literature on both republicanism and on East Asian politics has largely failed to confront. This book (...) addresses these challenges by surveying the latest theoretical contributions to the studies of republicanism in Western countries and the latest interpretations of how republicanism, including both communitarian republicanism and neo-Roman republicanism, has been appropriated in countries in East Asia. In particular, it deals with the key question of whether liberty as non-domination can work in non-Western contexts where the fundamental tenets of liberal democracy, such as moral individualism and value pluralism, do not predominate. Across three sections, the chapters first provide a conceptual overview of republicanism as a global political theory, they then consider how republicanism has historically been received, resisted, and translated into East Asia., and Ffinally, they examine how historically informed possibilities fit with the emergent needs of contemporary Northeast Asian societies. Overall, the contributors show that republicanism is an always-ongoing project, whose terms must be interpreted and translated into the various communities they inform. Normative considerations about whether or how republicanism applies in East Asia cannot be divorced from historical and empirical approaches which consider the various ways in which republican ideals reflect the realities of life there. Dealing with the issue of republicanism from a new, comparative perspective, this book will have broad appeal to students and scholars of Asian studies, comparative political theory, political philosophy, sociology, and history.

The analysis of Political Action Committee activities is dominated by the perspective that PAC contributions are a rational investment in political candidates; they yield valuable short-term payoffs. PACs buy access to officeholders and their votes on important legislation. Despite broad acceptance of this morally suspect theory, the evidence upon which it is based is weak. An alternative perspective — what we call the principled approach — both fits the evidence and rejects the morally repugnant interpretation of the relationship between business (...) and politics that permeates the rational investment perspective.

The Oxford or Tractarian Movement and later Ritualists and Anglo-Catholics schooled numerous converts in elements of the Catholic faith. Foremost among them was John Henry Cardinal Newman, one of the original founders of the Oxford Movement. Converts numbered in the hundreds and included another cardinal, Henry Edward Manning, the second Archbishop of Westminster, the religious foundress Cornelia Connelly, the priest novelist Robert Hugh Benson and later literary figures such as G.K. Chesterton, Evelyn Waugh and Mgr Ronald Knox. American historian, Patrick (...) Allitt, has argued that on both sides of the Atlantic converts dominated Catholic intellectual life between 1840 and 1960. While such 'Tractarian' converts have indeed greatly influenced Catholic life, many 'Tractarians' who never converted have also had a considerable impact on English-speaking Catholicism. C.S. Lewis is an obvious example. But there have been others, including author Charles Williams, poet T.S. Eliot and theologians John Macquarrie and Michael Ramsey. The author Dorothy L. Sayers also deserves to be counted among their number. (shrink)

There is not one but many ways to picture the world--Australian "x-ray" pictures, cubish collages, Amerindian split-style figures, and pictures in two-point perspective each draw attention to different features of what they represent. Understanding Pictures argues that this diversity is the central fact with which a theory of figurative pictures must reckon. Lopes advances the theory that identifying pictures' subjects is akin to recognizing objects whose appearances have changed over time. He develops a schema for categorizing the different ways pictures (...) represent--the different kinds of meaning they have--and argues that that depiction's epistemic value lies in its representational diversity. He also offers a novel account of the phenomenology of pictorial experience, comparing pictures to visual prostheses like mirrors and binoculars. (shrink)

What is computer art? Do the concepts we usually employ to talk about art, such as ‘meaning’, ‘form’ or ‘expression’ apply to computer art? _A Philosophy of Computer Art_ is the first book to explore these questions. Dominic Lopes argues that computer art challenges some of the basic tenets of traditional ways of thinking about and making art and that to understand computer art we need to place particular emphasis on terms such as ‘interactivity’ and ‘user’. Drawing on a (...) wealth of examples he also explains how the roles of the computer artist and computer art user distinguishes them from makers and spectators of traditional art forms and argues that computer art allows us to understand better the role of technology as an art medium.

Cooperation towards public goods relies on credible threats of punishment to deter cheats. However, punishing is costly, so it remains unclear who incurred the costs of enforcement in our evolutionary past. Theoretical work suggests that human cooperation may be promoted if people believe in supernatural punishment for moral transgressions. This theory is supported by new work in cognitive psychology and by anecdotal ethnographic evidence, but formal quantitative tests remain to be done. Using data from 186 societies around the globe, I (...) test whether the likelihood of supernatural punishment—indexed by the importance of moralizing “high gods”—is associated with cooperation.

One of the few points of agreement to be found in mainstream responses to the logical and semantic problems generated by vagueness is the view that if any modification of classical logic and semantics is required at all then it will only be such as to admit underdetermined reference and truth-value gaps. Logics of vagueness including many valued logics, fuzzy logics, and supervaluation logics all provide responses in accord with this view. The thought that an adequate response might require the (...) recognition of cases of overdetermination and truth value gluts has few supporters. This imbalance lacks justification. As it happens, Jaskowski's paraconsistent discussive logic-a logic which admits truth value gluts-can be defended by reflecting on similarities between it and the popular supervaluationist analysis of vagueness already in the philosophical literature. A simple dualisation of supervaluation semantics results in a paraconsistent logic of vagueness based on what has been termed subvaluational semantics. (shrink)

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to (...) one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.

This book offers a bold new approach to the philosophy of art. General theories of art don't work: they can't deal with problem cases. Instead of trying to define art, we should accept that a work of art is nothing but a work in one of the arts. Lopes's buck passing theory works well for the avant garde, illuminating its radical provocations.

The idea that the phenomenon of vagueness might be modelled by a paraconsistent logic has been little discussed in contemporary work on vagueness, just as the idea that paraconsistent logics might be fruitfully applied to the phenomenon of vagueness has been little discussed in contemporary work on paraconsistency. This is prima facie surprising given that the earliest formalisations of paraconsistent logics presented in Jaśkowski(1948) and Halldén(1949) were presented as logics of vagueness. One possible explanation for this is that, despite initial (...) advocacy by pioneers of paraconsistency, the prospects for a paraconsistent account of vagueness are so poor as to warrant little further consideration. In this paper we look at the reasons that might be offered in defence of this negative claim. As we shall show, they are far from compelling. Paraconsistent accounts of vagueness deserve further attention. (shrink)

A theory of aesthetic value should explain the performance of aesthetic experts, for aesthetic experts are agents who track aesthetic value. Aesthetic empiricism, the theory that an item's aesthetic value is its power to yield aesthetic pleasure, suggests that aesthetic experts are best at locating aesthetic pleasure, especially given aesthetic internalism, the view that aesthetic reasons always have motivating force. Problems with empiricism and internalism open the door to an alternative. Aesthetic experts perform a range of actions not aimed at (...) pleasure. Yet their reasons for acting are aesthetic. Since aesthetic values figure in aesthetic reasons, we can read a nonempiricist theory of aesthetic value off aesthetic experts’ reasons for acting. (shrink)

Williamson has argued against scepticism concerning our metaphysically modal knowledge, by arguing that standard patterns of suppositional reasoning to counterfactual conclusions provide reliable sources of correct ascriptions of possibility and necessity. The paper argues that, while Williamson’s claims relating to necessity may well be right, he has not provided adequate reasons for thinking that the familiar modes of counterfactual reasoning to which he points generalise to provide a decent route to ascriptions of possibility. The paper also explores another path to (...) ascriptions of possibility that may be extracted from Williamson’s ideas, before briefly considering the general status of counterfactual reasoning in relation to our knowledge of possibilities.

Kripkean examples of necessary a posteriori truths clearly provide a challenge to attempts to connect facts about possibility to facts about what people can conceive.

In this paper I offer a new interpretation of Stoic ontology. I aim to explain the nature of, and relations between, (i) the fundamental items of their physics, bodies; (ii) the incorporeal items about which they theorized no less; and (iii) universals, towards which the Stoic attitude seems to be a bizarre mixture of realism and anti-realism. In the first half of the paper I provide a new model to explain the relationship between those items in (i) and (ii). This (...) model clears up several problems in Stoicism and gives a precise answer to the question of how bodies and incorporeals differ in their mode of being. The second half of the paper considers the vexed issue of the status of those items in (iii), Stoic universals. (shrink)

The question "what is art?" is often said to be venerable and vexing. In fact, the following answer to the question should be obvious: (R) item x is a work of art if and only if x is a work in practice P and P is one of the arts. Yet (R) has appeared so far from obvious that nobody has given it a moment's thought. The trouble is not that anyone might seriously deny the truth of (R), but rather (...) that they will find it uninformative. After all, the vexing question is pressed upon us by radical changes in art of the avant-garde, and (R) offers no resources to address these changes. With that in mind, here is the case for (R). The challenges posed by the avant-garde are real enough and they need to be addressed, but the vexing question is the wrong question to ask to address them. It does not follow that the question has no good answer. On the contrary, (R) is all the answer we need, if we do not need an answer that addresses the challenges posed by the avant-garde. Moreover, (R) points to a question that we do need answered. So, not only is it true but, in addition, (R) is as informative as we need. (shrink)

This paper builds a three-part argument in favour of a more transcendentally focused form of ‘postphenomenology’ than is currently practised in philosophy of technology. It does so by problematising two key terms, ‘constitution’ and ‘postphenomenology’, then by arguing in favour of a ‘transcendental empiricist’ approach that draws on the work of Foucault, Derrida, and, in particular, Deleuze. Part one examines ‘constitution’, as it moves from the context of Husserl’s phenomenology to Ihde and Verbeek’s ‘postphenomenology’. I argue that the term tends (...) towards different senses in these contexts, and that this renders its sense more problematic than the work of Ihde and Verbeek makes it appear. Part two examines ‘postphenomenology’. I argue that putatively ‘poststructuralist’ thinkers such as Derrida, Foucault, and Deleuze may be better characterised as ‘postphenomenologists’, and that approaching them in this way may allow better access to their work from a philosophy of technology perspective. Part three argues for a ‘transcendental empiricist’ approach to philosophy of technology. In doing so, it argues for a rewriting of contemporary philosophy of technology’s political constitution: since an ‘empirical turn’ in the 1990s, I argue, philosophy of technology has been too narrowly focused on ‘empirical’ issues of fact, and not focused enough on ‘transcendental’ issues concerning conditions for these facts.

Four Arts of Photography explores the history of photography through the lens of philosophy and proposes a new understanding of the art form for the 21st century.

Visualizings, the simplest imaginings which employ visual imagery, have certain characteristic features; they are perspectival, for instance. Also, it seems that some but not all of our visualizings are imaginings of seeings. But it has been forcefully argued, for example by M.G.F. Martin and Christopher Peacocke, that all visualizings are imaginings of visual sensations. I block these arguments by providing an account of visualizings which allows for their perspectival nature and other features they typically have, but which also explains how (...) we can visualize things without thereby imagining visual sensations.

When we look at photographs we literally see the objects that they are of. But seeing photographs as photographs engages aesthetic interests that are not engaged by seeing the objects that they are of. These claims appear incompatible. Sceptics about photography as an art form have endorsed the first claim in order to show that there is no photographic aesthetic. Proponents of photography as an art form have insisted that seeing things in photographs is quite unlike seeing things face-to-face. This (...) paper argues that the claims are compatible. While seeing things in photographs is quite unlike seeing things face-to-face, nevertheless seeing things in photographs is one way of seeing things. The differences between seeing things by means of photographs and by means of the naked eye provide the elements of an account of the aesthetic interests photographs engage. (shrink)

Some philosophers—for example, Husserl, Alva Noë and Susanna Siegel—have claimed that the contents of visual sensations standardly include references to the later visual episodes that one would have under certain conditions. The current paper claims that there are no good reasons for accepting that view. Instead, it is argued that the conscious phenomena which have been cited as manifesting the presence within visual contents of references to ways that things would look in the course of later visual sensations are better (...) explained in another manner: in terms of references within the contents of ordinary visual sensations to ways that things actually then look from various perspectives.

A theory of aesthetic normativity states what makes it the case that the fact that an item is beautiful is reason to appreciate it. Aesthetic hedonists characteristically hold that the fact that an item is beautiful is reason to appreciate it because anyone always has reason to do what yields pleasure. Bernard Bolzano was an aesthetic hedonist who is best interpreted as offering a mixed theory of aesthetic normativity. The fact that an item is beautiful is reason to appreciate it (...) because anyone always has reason to do what yields pleasure and because anyone also has reason to do what fosters virtue, the capacity to act well. The argument for this interpretation knits together Bolzano’s aesthetics, his ethics, and his philosophy of science. In doing so, this argument opens up a new perspective on aesthetic normativity.

The addition of "actually" operators to modal languages allows us to capture important inferential behaviours which cannot be adequately captured in logics formulated in simpler languages. Previous work on modal logics containing "actually" operators has concentrated entirely upon extensions of KT5 and has employed a particular modeltheoretic treatment of them. This paper proves completeness and decidability results for a range of normal and nonnormal but quasi-normal propositional modal logics containing "actually" operators, the weakest of which are conservative extensions of K, (...) using a novel generalisation of the standard semantics.

Lopes (2010) offers an account of computer art, which he argues is a new art form. Part of what makes computer art distinctive, according to Lopes, is its interactivity, a quality found in few non-computer artworks. Given the rise in prominence of such artworks, most notably videogames, they are surely worthy of philosophical inquiry. I believe their ontology and properties are particularly worthy of study, as an understanding of these will prove crucial to critical understanding and evaluation of the works (...) themselves. Lopes’ account of interactive art is novel and important, but flawed, and in this essay I will discuss its flaws and suggest a better account of the properties of interactive art that builds on his work, providing a partial account of the ontology of interactive art. In Section 1, I discuss Lopes’ definition and ontology of interactive art; in Section 2, I argue that he only accounts for the properties of displays, neglecting the properties of interactive artworks themselves. In Section 3, I discuss several possible solutions for Lopes and why they are inadequate before Section 4 presents my view, that interactive artworks possess all of the properties of their varying displays because each possible display is part of the artwork. This is compatible with Lopes’ definition of interactive art, and so much of his account can be preserved, but with a refined account of the properties of interactive artworks. What I present is by no means a complete ontological study of interactive art, but hopefully lays the groundwork for future work on this ontology. (shrink)

It is widely assumed that the art media can be individuated with reference to the sense modalities. Different art media are perceived by means of different sense modalities, and this tells us what properties of each medium are aesthetically relevant. The case of pictures appears to fit this principle well, for pictures are deemed purely and paradigmatically visual representations. However, recent psychological studies show that congenitally and early blind people have the ability to interpret and make raised‐line drawings through touch. (...) This shows that pictures are not essentially visual representations. The view that pictures are essentially visual follows from influential views of the nature of depiction and of the nature of vision that are mistaken. By rooting out the mistake, we learn something about pictures, something about vision, and something about the doctrine that art media are individuated by the sense modalities. (shrink)

Internet plagiarism continues unabated and may even be increasing. Questions pertaining to the ethical-moral construct employed by students to justify Internet plagiarism among high school students have remained relatively untouched. Understanding not simply the prevalence of Internet plagiarism but also the variety of explanations used by students to justify their plagiarism seems crucial to curtailing its practice. In this study, I surveyed 160 high school students and endeavored to understand and describe the practices of students who use the Internet for (...) schoolwork and who engage in copy-paste plagiarism or paper-buying practices. The results indicate that students are more easily able to justify copy-paste plagiarism for a variety of reasons that mirror justifications of other forms of conventional plagiarism. Most students indicated they would never purchase a paper for reasons ranging from fear of getting caught to more principled and nuanced ethical claims. Based on these results I also offer educators suggestions for refining assignments and evaluation methods. (shrink)

This paper will reflect on the possibility of epistemic decolonization, particularly in terms of curriculum, as a transformative educational process in the context of the South African university, and with respect to my own positionality. The argument will centre around two difficult interdependent positions. On the one hand I will argue for the university’s task as transformational, even offering, via Cornel West, the ‘salvific’ possibility that knowledge offers those who seek it. To develop this claim, I will draw on and (...) develop the notion of paideia though the work of Plato and Heidegger.On the other hand, within the postcolonial African university, the question of decolonization in the tertiary space cannot be elided, particularly since the 2015 #RhodesMustFall and #FeesMustFall movements. The university is a powerful colonial relic, and it can be used to reinforce and perpetuate epistemic violence through unreflective or unconscious pedagogical and curriculum decisions. Here I draw on decolonial thinkers such as Santos, Mignolo, Maldonado-Torres, and Mbembe: I argue for a reckoning with the forces of coloniality, and advocate for epistemic justice and criticality, as part of the decolonizing project. In conclusion, working with ideas from Cornel West, I argue to reconcile paideia, as the ‘turning of the soul’, with the decolonizing African university. (shrink)

I argue that verbal models should be included in a philosophical account of the scientific practice of modelling. Weisberg (2013) has directly opposed this thesis on the grounds that verbal structures, if they are used in science, only merely describe models. I look at examples from Darwin's On the Origin of Species (1859) of verbally constructed narratives that I claim model the general phenomenon of evolution by natural selection. In each of the cases I look at, a particular scenario is (...) described that involves at least some fictitious elements but represents the salient causal components of natural selection. I pronounce the importance of prioritising observation of scientific practice for the philosophy of modelling and I suggest that there are other likely model types that are excluded from philosophical accounts.

In lieu of an abstract, here is a brief excerpt of the content:Introduction to the Special Section on Psychedelics Research and TreatmentDominic SistiAgainst a backdrop of post-pandemic malaise, diseases of despair, and a fragmented mental health care system, psychedelics have enjoyed a resurgence of interest as powerful psychotherapeutic agents and as catalysts of personal growth. The true power of these substances—some of which are considered sacramental by Indigenous peoples—has been shrouded for half a century by cultural mythology, political propaganda, and (...) misuse. From about 1940 to 1970, psychedelics including psilocybin and LSD were studied and used by clinicians to treat a range of psychiatric disorders from alcoholism and depression in adults to "autistic schizophrenia" in children.In June 1971, the Nixon administration's racist and illiberal War on Drugs inaugurated what was essentially a total ban on psychedelics. Society was robbed of half a century of scientific progress, and one can only speculate how differently our society might now function, and how many people might have been spared the trauma of mental illness and incarceration. Thankfully, it appears the time has arrived for psychedelic medicines to be decriminalized and included again in the pharmacopeia.In June 2023, a group of psychedelic researchers, therapists, bioethicists, Indigenous scholars, and advocates met at the Banbury Conference Center at Cold Spring Harbor Laboratory. There, this interdisciplinary group discussed several pressing ethical issues in psychedelics research and treatment that continue to [End Page 114] challenge the field. The aim of this meeting was to develop a bioethical framework for the use of psychedelics in mainstream medical settings. That is, how should psychedelics be employed responsibly by everyday clinicians, including psychiatrists, psychologists, social workers, and other behavioral health-care providers? This special section offers a sampling of three topics in psychedelic bioethics raised by the Banbury group, several of whom appear as coauthors.In our first paper, Logan Neitzke-Spruill and colleagues offer an overview of explanatory models describing the therapeutic mechanisms of psychedelic substances and how each of these models generates unique ethical quandaries. Starting from molecular biology and moving to neural circuitry and networks, neurobiological models now propel contemporary scientific research into psychedelics. Knowing how these substances work on a molecular level may offer promising ways forward in the development of new molecules designed to treat serious mental illnesses and other neurologic conditions. Perhaps neuroplastic mechanisms will be harnessed to develop new therapies without necessitating a psychedelic trip—a controversial premise discussed in our third paper, by Katherine Cheung, Brian Earp, and David Yaden.Such "neuroreductionism" risks ignoring the subjective psychological and spiritual experiences of patients that appear to be pivotal in psychedelic-assisted therapy, often described as mystical and utterly transformative. At the psychological level, these substances engender a kind of vulnerability and suggestibility requiring clear ethical standards to ensure patients' psychological and physical safety. And so too, practitioners will need structural and cultural competency to recognize the spiritual or moral values that inspire patient reactions during and after their psychedelic experiences. Ethically informed psychedelic practitioners will have to navigate between disciplinary silos and explanatory models. One practical upshot is the open question of how best to train psychedelic practitioners who hold this broad set of competencies.To that end, well-trained practitioners will need to be able to disclose in some way the transformative properties of psychedelics to prepare patients for their experiences. But how does one describe the ineffable? This raises the question of how or if it is possible for patients to truly consent to the transformative experience elicited by psychedelics, often described as one of the most important experiences of a person's life. The experience might stimulate significant emotional healing, or it might be horrifying. This sounds like a problem uniquely attached to psychedelics: after all, most pharmaceuticals don't trigger changes in one's fundamental moral values, life choices, and commitments, nor are they intended to. Yet, Brent Kious, Andrew Peterson, and Amy McGuire challenge the view that the psychedelic experience is uniquely transformative and impervious to the disclosure requirements of informed consent, a bedrock of bioethics. Ultimately, the writers show how consent is possible even if the experiences are dramatically different from most medical interventions, endorsing a practical view of consent [End... (shrink)

Wakefield's (2000) responses to our paper herein (Murphy and Woolfolk 2000) are not only unsuccessful, they force him into a position that leaves him unable to preserve any distinction between disorders and other problems. They also conflate distinct scientific concepts of function. Further, Wakefield fails to show that ascriptions of human dysfunction do not ineliminably involve values. -/- We suggest Wakefield is analyzing a concept that plays a role in commonsense thought and arguing that the task of science is to (...) identify the natural processes that accord with that commonsense concept. We argue that this represents an attempt to use conceptual analysis to legislate what should be acceptable science. We conclude that this constraint on science is unacceptable and that therefore Wakefield's overall position should be rejected. (shrink)
