There are a number of dimensions to the realism-nominalism controversy. The topics of debate comprise: necessary connections and causality, dispositions and counterfactuals, space and time, the existence of abstract entities and mathematical objects, the existence of the theoretical entities of science. On all these except the last, Sellars takes a non-realist line: and on all these except the last, I agree with him to the extent that I presently have an opinion on them. But Sellars is a scientific realist, encapsulating (...) this realism in the dictum: “to have good reason for holding a theory is ipso facto to have good reason for holding that the entities postulated by the theory exist”.

In a recent paper Johan van Benthem reviews earlier work done by himself and colleagues on ‘natural logic’. His paper makes a number of challenging comments on the relationships between traditional logic, modern logic and natural logic. I respond to his challenge, by drawing what I think are the most significant lines dividing traditional logic from modern. The leading difference is in the way logic is expected to be used for checking arguments. For traditionals the checking is local, i.e. separately (...) for each inference step. Between inference steps, several kinds of paraphrasing are allowed. Today we formalise globally: we choose a symbolisation that works for the entire argument, and thus we eliminate intuitive steps and changes of viewpoint during the argument. Frege and Peano recast the logical rules so as to make this possible. I comment also on the traditional assumption that logical processing takes place at the top syntactic level, and I question Johan’s view that natural logic is ‘natural’. (shrink)

There are striking differences between the scientific theoretical description of the world and the way it seems to us. The consequent task of relating science to ’the world we live in’ has been a problem throughout the history of science. But have we made this an impossibility by how we formulate the problem? Some say that besides the successive world-pictures of science there is the world-picture that preceded all these and continues to exist by their side, elucidated by more humanistic (...) philosophers. Wilfrid Sellars codified this conviction in his dichotomy of scientific image and manifest image. Others say that all our world-pictures are transient, evolve, conflict with and replace each other, undergo violent revolutions as well as periods of normal development, and may be incommensurable, allowing of no meaningful dialogue. All such formulations may themselves be tendentious metaphysics, full of false contrasts. Insistence on a radical separation between science and what we have apart from science, on the impossibility of accommodating science without surrender, may be a way of either idolizing or demonizing science rather than understanding it.

While 4E approaches to cognition are increasingly introduced in educational contexts, little has been said about how 4E commitments can inform pedagogy aimed at fostering ethical competencies. Here, we evaluate a 4E-inspired ethics exercise that we developed at a technical university to enliven the moral imagination of engineering students. Our students participated in an interactive tinkering workshop, during which they materially redesigned a healthcare artifact. The aim of the workshop was twofold. Firstly, we wanted students to experience how material choices (...) at the levels of design and functionality can enable morally significant reimaginings of the affordances commonly associated with existing artifacts. We term this type of reimagining world-directed moral imagination. Secondly, through the design process, we wanted students to robustly place themselves in the lived embodied perspectives of (potential) users of their selected artifacts. We term this person-directed moral imagination. While student testimonies about the exercise indicate that both their world-directed and person-directed moral imagination were enlivened, we note that the fostering of robust person-directed moral imagination proved challenging. Using 4E insights, we diagnose this challenge and ask how it might be overcome. To this end, we engage extensively with a recent 4E-informed critique of person-directed moral imagination, raised by Clavel Vázquez and Clavel-Vázquez (2023). They argue that person-directed moral imagination is profoundly limited, if not fundamentally misguided, particularly when exercised in contexts marked by emphatic embodied situated difference between the imaginer and the imagined. Building upon insights from both the 4E field and testimonies from critical disability studies, we argue that, while their critique is valuable, it ultimately goes too far. We conclude that a 4E approach can take on board recent 4E warnings regarding the limits of person-directed moral imagination while contributing positively to the development of moral imagination in engineering ethics education.

Maarten Boudry and Jerry Coyne have written a piece, forthcoming in Philosophical Psychology, called “Disbelief in Belief,” in which they criticize my recent paper “Religious credence is not factual belief” (2014, Cognition 133). Here I respond to their criticisms, the thrust of which is that we shouldn’t distinguish religious credence from factual belief, contrary to what I say. I respond that their picture of religious psychology undermines our ability to distinguish common religious people from fanatics. My response will appear in (...) the same issue as their paper.

This paper challenges the two aims of Michael Cholbi’s Rational Will View (RWV) which are to (1) offer an account of why paternalism is presumptively or pro tanto wrong and (2) relate the relative wrongness of paternalistic interventions to the rational powers that such interventions target (Sections 1 and 2). Some of a paternalizee’s choices harm their future selves in ways that would be wrong if they were done to others. I claim this challenges Cholbi’s second aim (2) because the (...) cases his account deems particularly wrong turn out to be not to be as wrongful as expected (Section 3). When this second aim is challenged, it has knock-on effects on the capacity of the RWV to discern which cases of paternalism are generally more wrongful than others, which undermines Cholbi’s first aim (1). I consider responses on behalf of Cholbi’s view but conclude that the account is insufficient on its own to vindicate its two aims (Section 4). Finally, I draw on recent work that adopts ideas from the practical reasoning literature to help determine paternalism’s wrongness (Section 5). I argue this helps Cholbi’s view withstand my objections, but we must remain skeptical of why interceding with rational powers is particularly wrong. (shrink)

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

Abstract‘Social inclusion’ is the leading ideal in services and care for people with intellectual disabilities in most countries in the Global North. ‘Social inclusion’ can refer simply to full equal rights, but more often it is taken to mean something like ‘community participation’. This narrow version of social inclusion has become so ingrained that it virtually goes unchallenged. The presumption appears to be that there is a clear moral consensus that this narrow understanding of social inclusion is good. However, that (...) moral consensus is not clear in the case of people with profound intellectual and/or multiple disabilities (PIMD), who are not able to express their needs and preferences verbally. Moreover, social inclusion has proven to be difficult to conceptualize and implement for people with PIMD. Therefore, it becomes imperative to ask about the ethical rationale of the narrow understanding of social inclusion. For what reasons do we think social inclusion is good? And do those reasons also apply for people with PIMD? This article addresses these questions by providing an ethical analysis of the ideal of social inclusion for people with PIMD. It discusses four ethical arguments for social inclusion and probes their relevance for people with PIMD. The article argues that none of these arguments fully convince of the value of the narrow understanding of social inclusion for people with PIMD. It ends with advocating for an ethical space for imagining a good life for people with PIMD otherwise. (shrink)

Nelson Goodman’s attempt to analyse the expressiveness of artworks in semantic terms has been widely criticised. In this paper I try to show how the use of an adapted version of his concept of exemplification, as proposed by Mark Textor, can help to alleviate the worst problems with his theory of expression. More particularly I argue that the recognition of an intention, which is central to Textor’s account of exemplification, is also fundamental to our understanding of expressiveness in art. Moreover (...) I propose that the recognition of this intention depends on our interpretation of the artwork – an insight Goodman tried to capture with his assertion that our attributions of expressive properties to artworks function metaphorically. The realisation of the context-dependence of our expressive judgements about art and, hence, of the central role interpretation plays in these judgements, I contend, counts in favour of theories of expression like Goodman’s that focus on semantic concerns.

Bernard Williams argued that historical and philosophical inquiry were importantly linked in a number of ways. This introductory chapter distinguishes four different connections he identified between philosophy and history. (1) He believed that philosophy could not ignore its own history in the way that science can. (2) He thought that when engaging with philosophy’s history primarily to produce history, one still had to draw on philosophy. (3) Even doing history of philosophy philosophically, i.e. primarily to produce philosophy, required a keen (...) sense of how historically distant from us past philosophers were, on his view, because the point of reading them was to confront something different from the present. (4) He held that systematic philosophy itself needed to be done historically, engaging not necessarily with its own history, but with that of the concepts it sought to understand. The chapter closes with an overview of the volume’s structure and content. (shrink)

Under review at Canadian Journal of Philosophy. This paper does five things: (1) It provides an analysis of meta-ethical Non-Realist Cognitivism. (2) It assesses two arguments in favour of the view which have been largely overlooked in analyses so far. (3) It argues that different proponents of the view offer crucially different strategies for vindicating moral objectivity without the metaphysical commitments of traditional non-naturalism. (4) Contrary to other commentators, it argues for the no-truthmaker interpretation of Parfit’s view. (5) It argues (...) that each version of Non-Realist Cognitivism is unlikely to be able to do the explanatory work that seemed to call for an ontologically committal non-naturalism. (shrink)

Research shows that after layoffs, employees often report decreased commitment and performance which has been coined the survivor syndrome. However, the mechanisms underlying this effect remain underexplored. The purpose of the paper is to show that reduced organizational identification can serve as an explanation for the survivor syndrome. We conducted a laboratory experiment, in which participants work as a group of employees for another participant who acts as employer. In the course of the experiment, the employer decides whether one of (...) his or her employees should be laid off or not. Mediation analysis supports a social identity-based explanation for the emergence of the survivor syndrome: downsizing causes lower identification with the employer which in turn relates to lower performance of employees.

According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, (...) and only sustained empirical research in cognitive science will determine the extent to which that is true. (shrink)

This paper has two parts. In the first part, I concede an error in an argument I have given for the incompatibility of free will and determinism. I go on to show how to modify my argument so as to avoid this error, and conclude that the thesis that free will and determinism are compatible continues to be—to say the least—implausible. But if free will is incompatible with determinism, we are faced with a mystery, for free will undeniably exists, and (...) it also seems to be incompatible with indeterminism. In the second part of this paper, I will defend the conclusion that the concept of agent causation is of no use to the philosopher who wants to maintain that free will and indeterminism are compatible. I conclude that free will remains a mystery---that is, that free will undeniably exists and that there is a strong and unanswered prima facie case for its impossibility. (shrink)

What do players of videogames mean when they say they want to shoot zombies? Surely they know that the zombies are not real, and that they cannot really shoot them, but only control a fictional character who does so. Some philosophers of fiction argue that we need the concept of imaginative desires to explain situations in which people feel desires towards fictional characters or desires that motivate pretend actions. Others claim that we can explain these situations without complicating human psychology (...) with a novel mental state. Within their debates, however, these scholars exclusively focus on non-interactive fictions and children’s games of make-believe. In this paper, I argue that our experience of immersive, interactive fictions like videogames gives us cause to reappraise the concept of imaginative desires. Moreover, I describe how i-desires are a useful conceptual tool within videogame development and can shed new light on apparently immoral in-game actions. (shrink)

In this paper, the author considers five basic understandings of metaphysics as a philosophical discipline that 1) studies the most general characteristics of everything that is, 2) investigates beings as beings, 3) considers what goes beyond the framework of experience, 4) analyses the most general terms and 5) provides an explanatory theory. In addition, the author considers a number of relevant ideas and distinctions, the distinction between reality and appearance, the distinction between the apparent and scientific picture of the world (...) (Wilfrid Sellars), the idea that philosophy is the queen of science (Moritz Schlick), the distinction between descriptive and revisionist metaphysics (Peter Frederick Strawson), the synoptic view, the idea of naturalised metaphysics, etc. The author accepts the first point of view, the one according to which metaphysics is understood as a philosophical discipline that studies the most general characteristics of everything that is, and accordingly believes that categorical ontology best fits into that picture. After that, the author briefly presents the most famous criticisms of metaphysics (David Hume, Immanuel Kant, and logical positivists), as well as the positions that led to the formation of modern metametaphysics (Rudolf Carnap and Willard Van Orman Quine). Finally, the author considers verbalism and trivialism and tries to determine whether these two positions can represent a basis for the elimination of metaphysics. The author tries to show that these positions do not eliminate metaphysics, but rather set the framework for contemporary metaphysical discussions. (shrink)

The method of positron emission tomography illustrates the circular logic popular in subtractive neuroimaging and linear reductive cognitive psychology. Both require that strictly feed-forward, modular, cognitive components exist, before the fact, to justify the inference of particular components from images after the fact. Also, both require a "true" componential theory of cognition and laboratory tasks, before the fact, to guarantee reliable choices for subtractive contrasts. None of these possibilities are likely. Consequently, linear reductive analysis has failed to yield general, reliable, (...) componential accounts. (shrink)

The Russian invasion of Ukraine on February 24, 2022, has already caused large amounts of greenhouse gas (GHG) emissions and will continue to do so for manyyears after hostilities have ceased mainly because of the emissions linked to the rebuilding of destroyed or damaged housing, public buildings, infrastructure, factories, and the like. My aim in this paper is to discuss how in a time of climate emergency such emissions of war should impact the political morality of states initiating, continuing, and (...) ending war (through a just and enduring peace) as understood by just war theory (JWT). My point of departure is a study by Lennard de Klerk and six co-authors detailing the emissions of the first year of the Russo-Ukrainian war. (shrink)

I first highlight a main theme of the collection I edited and issued last year, Realism, Science and Pragmatism, by contrasting classical pragmatism and neo-pragmatism in terms of the distinction between semantic externalism and semantic internalism, and exhibiting how both of these semantic views are concisely stated by Carnap, though neither he nor his followers recognised this contrast, nor its profound methodological and substantive implications – although they were highlighted at the time by Wick, published by Wilfrid Sellars and (...) Herbert Feigl in the second year of their journal, Philosophical Studies. I exhibit the continuing influence of semantic internalism – which dominates Quine’s, Rorty’s, van Fraassen’s, Brandom’s and Huw Price’s neo-pragmatist views – and argue against it with pragmatic realist considerations drawn from Kant, Carnap and Sellars.

Decentralized clinical trials (DCTs) have the potential to advance the conduct of clinical trials, but raise several ethical issues, including obtaining valid informed consent. The debate on the ethical issues resulting from digitalization is predominantly focused on direct risks relating to for example data protection, safety, and data quality. We submit however, that a broader view on ethical aspects of DCTs is needed to touch upon the new challenges that come with the DCT practice. Digitalization has impacts that go beyond (...) its direct purposes, by shaping behaviors, experiences, social relations, and values. We examine four elements of the informed consent procedure that are affected by DCTs, while taking these soft impacts of technologies into account: (i) informing participants and testing understanding, (ii) freedoms in relation to responsibilities and burdens, (iii) trust in participant-researcher relations, and (iv) impacts on the concept of privacy. Our analysis reveals that a broad view is key for optimal conduct of DCTs. In addition, it provides insight into the ethical impacts of DCTs on informed consent. Technologies such as DCTs potentially have profound impacts which are not immediately addressed by the existing regulatory frameworks, but nonetheless important to recognize. These findings can guide future practices of DCTs to foster the important values of clinical research in this novel approach for conducting clinical trials. (shrink)

For Bernard Williams, philosophy and history are importantly connected. His work exploits this connection in a number of directions: he believes that philosophy cannot ignore its own history the way science can; that even when engaging with philosophy’s history primarily to produce history, one needs to draw on philosophy; and that when doing the history of philosophy primarily to produce philosophy, one still needs a sense of how historically distant past philosophers are, because the point of reading them is to (...) confront something different from the present. But Williams also holds that systematic philosophy itself needs to be done historically, engaging not just with its own history, but with that of the concepts it seeks to understand. To explore these different ways in which philosophy and history intertwine, this volume assembles specially commissioned contributions by A. W. Moore, Terence Irwin, Sophie-Grace Chappell, Catherine Rowett, Marcel van Ackeren, John Cottingham, Gerald Lang, Lorenzo Greco, Paul Russell, Carla Bagnoli, Peter Kail, David Owen, Giuseppina D’Oro, James Connelly, Matthieu Queloz, Nikhil Krishnan, John Marenbon, Ralph Wedgwood, Garrett Cullity, Hans-Johann Glock, Geraldine Ng, Ilaria Cozzaglio, Amanda R. Greene, and Miranda Fricker. They critically appraise Williams’s work in and on the history of philosophy as well as his historicist turn and his use of genealogy. The resulting collection uniquely combines substantive discussions of historical figures from Homer to Wittgenstein with methodological discussions of how and why the history of philosophy should be done, and how and why philosophy should draw on history.

The concept of Smart Healthy Age-Friendly Environments (SHAFE) emphasises the comprehensive person-centred experience as essential to promoting living environments. SHAFE takes an interdisciplinary approach, conceptualising complete and multidisciplinary solutions for an inclusive society. From this approach, we promote participation, health, and well-being experiences by finding the best possible combinations of social, physical, and digital solutions in the community. This initiative emerged bottom-up in Europe from the dream and conviction that innovation can improve health equity, foster caring communities, and sustainable development. (...) Smart, adaptable, and inclusive solutions can promote and support independence and autonomy throughout the lifespan, regardless of age, gender, disabilities, cultural differences, and personal choices, as well as promote happier and fairer living places. The New European Bauhaus initiative gathers “beautiful, sustainable, and inclusive projects and ideas” to inspire a positive transformation around us. The New European Bauhaus 2024 Festival took place between 9-13 April. “Designing the perfect New European Bauhaus neighbourhood: New European Bauhaus meets SHAFE” was a Satellite Event of the Festival, held as an online workshop, organised by the SHAFE Foundation on April 9th, 2024. At the event, a group of 50 participants with a multidisciplinary background discussed how to meet the challenges of the European Garcia family to enable them to live in a perfect neighbourhood. The White Paper presents the findings of the participants with the New European Bauhaus inspiring projects and ideas to house the European Garcia family in their neighbourhood. The White Paper recommends developers, designers, planners, and policymakers to include person-centred design of social and physical environments and technologies. Although awareness of person-centred design is growing, many initiatives still hamper the inclusion of citizens or end-users throughout the development of products and services. (shrink)

The guiding premise of this chapter is that we, as teachers in higher education, must consider how the content and form of our teaching can foster inclusivity through a responsiveness to neurodiverse learning styles. A narrow pedagogical focus on lectures, textual engagement, and essay-writing threatens to exclude neurodivergent students whose ways of learning and making sense of the world may not be best supported through these traditional forms of pedagogy. As we discuss in this chapter, we, as engineering ethics educators, (...) designed and implemented a new engineering ethics exercise with which we aimed to promote inclusivity at the levels of form and content. At the content level, students were invited to critically engage with inclusivity-undermining ableist assumptions in technology development. This took shape, at the formal level, through a hands-on ‘material tinkering’ workshop in which students collaboratively and creatively altered (or ‘hacked’) artifacts used in contexts of disability and healthcare, so as to operationalize values of inclusivity and accessibility. Our hunch was that this hands-on tinkering workshop would simultaneously encourage a meaningful way of engagement with these ethical issues and values, while also enacting a more inclusive learning environment by enriching the range of pedagogical activities and learning formats available to our students. As we aim to show in this chapter, we believe this hunch largely panned out - though there are clear areas for future improvement pertaining to the pilot exercise itself and the research we conducted on the exercise. We begin by offering a description of our tinkering exercise. We discuss the exercise’s source of inspiration (2.1) and its implementation (2.2), which is visually captured via photographic documentation. We then discuss (3) how we utilized a triangulated research method to assess the pedagogical value of the exercise. After we discuss our findings, we conclude by identifying areas for future improvement (4). (shrink)

Though most contemporary philosophers and scientists accept a physicalist view of mind, the recent surge of interest in the problem of consciousness has put the mind /body problem back into play. The physicalists' lack of success in dispelling the air of residual mystery that surrounds the question of how consciousness might be physically explained has led to a proliferation of options. Some offer alternative formulations of physicalism, but others forgo physicalism in favour of views that are more dualistic or that (...) bring in mentalistic features at the ground- floor level of reality as in pan-proto-psychism. My aim here is to give an overview of the recent philosophic discussion to serve as a map in locating issues and options. I will not offer a comprehensive survey of the debate or mark every important variant to be found in the recent literature. I will mark the principal features of the philosophic landscape that one might use as general orientation points in navigating the terrain. I will focus in particular on three central and interrelated ideas: those of emergence, reduction, and nonreductive physicalism. The third of these, which has emerged as more or less the majority view among current philosophers of mind, combines a pluralist view about the diversity of what needs to be explained by science with an underlying metaphysical commitment to the physical as the ultimate basis of all that is real. The view has been challenged from both left and right, on one side from dualists and on the other from hard core reductive materialists. Despite their differences, those critics agree in finding nonreductive physicalism an unacceptable and perhaps even incoherent position. They agree as well in treating reducibility as the essential criterion for physicality; they differ only about whether the criterion can be met. Reductive physicalists argue that it can, and dualists deny it. (shrink)
