In this article, we examine the intimate significance of trees and woods through research on how people engage with and perform their bodies in different kinds of wooded environments in contemporary Britain. We argue that there are significant, contested and ambivalent affordances provided by woods and forests in contemporary Britain - as providing `live' contact with nature, as a source of tranquillity, and as providing a distinct `social' space in sharp contrast to the pressures of modern living. Second, there is (...) considerable variation in the bodily experiences that people gain from woods and forests, influenced by personal and family life-stage, socio-economic circumstance and geographical location. The values people appear to attach to woods and forests arise from the specific `affordances' that the latter could offer for bodily desires. There are, we might say, different `contested' natures of the forest. (shrink)

In this article we argue that nanotechnology represents an extraordinary opportunity to build in a robust role for the social sciences in a technology that remains at an early, and hence undetermined, stage of development. We examine policy dynamics in both the United States and United Kingdom aimed at both opening up, and closing down, the role of the social sciences in nanotechnologies. We then set out a prospective agenda for the social sciences and its potential in the future shaping (...) of nanotechnology research and innovation processes. The emergent, undetermined nature of nanotechnologies calls for an open, experimental, and interdisciplinary model of social science research. (shrink)

This paper contributes towards a lay ethics of nanotechnology through an analysis of talk from focus groups designed to examine how laypeople grapple with the meaning of a technology ‘in-the-making’. We describe the content of lay ethical concerns before suggesting that this content can be understood as being structured by five archetypal narratives which underpin talk. These we term: ‘the rich get richer and the poor get poorer’; ‘kept in the dark’; ‘opening Pandora’s box’; ‘messing with nature’; and ‘be careful (...) what you wish for’. We further suggest that these narratives can be understood as sharing an emphasis on the ‘giftedness’ of life, and that together they are used to resist dominant technoscientific and Enlightenment narratives of control and mastery which are encapsulated by nanotechnology.

The rapid development of CRISPR-based gene editing has been accompanied by a polarized governance debate about the status of CRISPR-edited crops as genetically modified organisms. This article argues that the polarization around the governance of gene editing partly reflects a failure of public engagement with the current state of research in genomics and postgenomics. CRISPR-based gene-editing technology has become embedded in a narrow narrative about the ease and precision of the technique that presents the gene as a stable object under (...) technological control. By tracing the considerably destabilized scientific understanding of the gene in genomics and postgenomics, this article highlights that this publicly mediated ontology strategically avoids positioning the “ease of CRISPR-based editing” in the wider context of the “complexity of the gene.” While this strategic narrowness of CRISPR narratives aims to create public support for gene-editing technologies, we argue that it stands in the way of socially desirable anticipatory governance and open public dialogue about societal promises and the unintended consequences of gene editing. In addressing the polarization surrounding CRISPR-based editing technology, the article emphasizes the need for engagement with the complex state of postgenomic science that avoids strategic simplifications of the scientific literature in promoting or opposing the commercial use of the gene-editing technology.

In this paper, we respond to a critique by Erik Thorstensen of the ‘Deepening Ethical Engagement and Participation in Emerging Nanotechnologies’ project concerning its ‘realist’ treatment of narrative, its restricted analytical framework and resources, its apparent confusion in focus and its unjustified contextualisation and overextension of its findings. We show that these criticisms are based on fairly serious misunderstandings of the DEEPEN project, its interdisciplinary approachand its conceptual context. Having responded to Thorstensen’s criticisms, we take the opportunity to clarify and (...) develop our approach to narrative. We articulate the need for novel, theoretically robust approaches to the formation of public attitudes which transcend the limitations of both survey-based approaches—which remain wedded to methodological individualism and which presume that individuals hold distinct and relatively stable attitudes and preferences—and interactionist approaches to public talk, which focus too strongly on individuals-in-interaction as reasoning agents and which ignore the constitutive role of culture and discourse in the formation of public opinion. We suggest that our use of narrative can help to better understand the process through which public attitudes to emerging technology develop out of interactive an engagement with wider cultural arguments and accounts of science and technology. We finish by pointing to parallel developments in social thought—from Charles Taylor’s treatment of social imaginaries to recent developments in post-Bourdieuian cultural sociology—as related projects in understanding the cultural resources and grammars that provide the conceptual infrastructure for modern social life.

This book develops an integrated perspective on the practices and politics of making knowledge work in inclusive development and innovation. While debates about development and innovation commonly appeal to the authority of academic researchers, many current approaches emphasize the plurality of actors with relevant expertise for addressing livelihood challenges. Adopting an action-oriented and reflexive approach, this volume explores the variety of ways in which knowledge works, paying particular attention to dilemmas and controversies. The six parts of the book address the (...) complex interplay of knowledge and politics, starting with the need for knowledge integration in the first part and decolonial perspectives on the politics of knowledge integration in the second part. The following three parts focus on the practices of inclusive development and innovation through three major themes of transformative learning, evidence, and digitization. The final part of the book addresses the governance of knowledge and innovation in the light of political struggles about inclusivity. Exploring conceptual and practical themes through case studies from the Global North and South, this book will be of great interest to students, scholars and practitioners researching and working in development studies, epistemology, innovation studies, science and technology studies and sustainability studies more broadly.

We reflect on a decade of Responsible Research and Innovation (RRI) as a discourse emerging from the European Commission (EC) 10 years ago. We discuss the foundations for RRI, its emergence during the Seventh Framework programme and its subsequent evolution during Horizon 2020.

We consider the prospects for RRI within the context of the EC’s Open Science agenda (...) and Horizon Europe programme, before closing with some reflections on the contribution RRI has made to debates concerning the relationship between science, innovation and society over the last decade.

How can one discover the ethical issues associated with nanotechnologies? One heuristic is to tend closely to the ethical reflections of lay publics and the ways in which these are informed by experience with technological innovation, technology governance, and the (broken) promises of visionary science and technology. A close collaboration between social scientists and philosophers took this heuristic to its limits: On the one hand, it achieved remarkably fine–grained insights into public reflection about nanotechnologies. On the other hand, a philosophical (...) analysis of these reflections makes apparent that there is a profound disconnect between the lay ethics rooted in public talk and the ethical and normative commitments that are embedded in nanotechnological research programs and practices. Accordingly, critical engagement with the ways in which ordinary people try to make sense of nanotechnologies constitutes a novel heuristic for the discovery of ethical issues. This introduction and the subsequent four papers show this heuristic at work. (shrink)

Innovation leads to new products, business models and even changes to socio-economic systems. However, it is important that innovation has the ‘right impacts’. Responsible innovation can help to achieve this; however, it is unclear how to introduce responsible innovation to real-world, competitive, industry settings. We explore this challenge in the context of sustainability orientated start-up enterprises, developing innovations within agriculture, food or energy. We develop a tool that provides innovators with a systematic way to identify socio-ethical issues. Using the concept (...) of experiential learning, we track the impact of the tool across 12 cases. For the tool to install responsible innovation, we propose that a full learning cycle must be completed. We find evidence that the tool can enable a full learning cycle and provide a method to identify socio-ethical factors. We contribute by articulating and operationalising an approach to introduce responsible innovation principles into real-world contexts. (shrink)

Philosophical Dilemmas: A Pro and Con Introduction to the Major Questions, 2/e, is a lucidly written and comprehensive introduction to philosophy featuring sixty brief essays arranged in pairs. Each pair answers one of the standard philosophical questions, such as "Does God exist?" or "Is morality relative?," with affirmative and negative responses. Each essay takes a definite stand and promotes it vigorously, creating a sharp contrast between the two positions and giving each abstract theory a more personal and believable "voice." While (...) the essays often employ traditional arguments of great philosophers, they present the ideas in contemporary language with vivid examples. The accessible style and conflicting answers encourage students to examine the different positions and to think carefully about which essay makes the stronger case. While other textbooks present a series of excerpts and theories without attempting to coordinate them into a larger picture, Philosophical Dilemmas teaches students about the process of thinking philosophically and encourages them to construct their own coherent worldviews. This second edition features new sections on race, gender, euthanasia, and Buddhist philosophy, showing students how philosophy applies to issues that they may encounter in their own lives. The text incorporates numerous pedagogical features including a list of historical parallels, key terms, chapter summaries, a glossary, an introduction to each issue, and critical questions following each essay. Brief sections throughout the book describe numerous critical thinking techniques demonstrated by the essays. An annotated bibliography of historical examples for each issue and useful lists of contemporary sources further enhance the text's utility. An Instructor's Manual, including chapter summaries, writing assignments, and test questions, is available. (shrink)

The Vocabulary of Critical Thinkingtakes an innovative, practical, and accessible approach to teaching critical thinking and reasoning skills. With the underlying notion that a good way to practice fundamental reasoning skills is to learn to name them, the text explores one hundred and eight words that are important to know and employ within any discipline. These words are about comparing, generalizing, explaining, inferring, judging sources, evaluating, referring, assuming and creating - actions used to assess relationships and arguments - and the (...) words are grouped according to these and other concepts essential to critical thinking. Featuring five or more words and an introduction on how they are related, each chapter is organized into three parts. Part I includes definitions of the words, brief examples of their use, and matching exercises. To further contextualize the words, Part II, Understanding the Meaning, provides numerous real-world examples, with commentary, of the words in use. Finally, Part III, providing practice of the associated critical thinking skills. Questions also appear throughout the chapters to encourage reflection and to highlight important points. Thirty-five photographs and illustrations additionally enrich the text. The book is an ideal text for critical thinking and reasoning courses as well as a variety of courses that prepare students to succeed. (shrink)

In a recent paper (1994) Wesley Salmon has replied to criticisms (e.g., Dowe 1992c, Kitcher 1989) of his (1984) theory of causality, and has offered a revised theory which, he argues, is not open to those criticisms. The key change concerns the characterization of causal processes, where Salmon has traded "the capacity for mark transmission" for "the transmission of an invariant quantity." Salmon argues against the view presented in Dowe (1992c), namely that the concept of "possession of a conserved quantity" (...) is sufficient to account for the difference between causal and pseudo processes. Here that view is defended, and important questions are raised about the notion of transmission and about gerrymandered aggregates. (shrink)

This book, published in 2000, is a clear account of causation based firmly in contemporary science. Dowe discusses in a systematic way, a positive account of causation: the conserved quantities account of causal processes which he has been developing over the last ten years. The book describes causal processes and interactions in terms of conserved quantities: a causal process is the worldline of an object which possesses a conserved quantity, and a causal interaction involves the exchange of conserved quantities. Further, (...) things that are properly called cause and effect are appropriately connected by a set of causal processes and interactions. The distinction between cause and effect is explained in terms of a version of the fork theory: the direction of a certain kind of ordered pattern of events in the world. This particular version has the virtue that it allows for the possibility of backwards causation, and therefore time travel. (shrink)

Although arguments for and against competing theories of vagueness often appeal to claims about the use of vague predicates by ordinary speakers, such claims are rarely tested. An exception is Bonini et al. (1999), who report empirical results on the use of vague predicates by Italian speakers, and take the results to count in favor of epistemicism. Yet several methodological difficulties mar their experiments; we outline these problems and devise revised experiments that do not show the same results. We then (...) describe three additional empirical studies that investigate further claims in the literature on vagueness: the hypothesis that speakers confuse ‘P’ with ‘definitely P’, the relative persuasiveness of different formulations of the inductive premise of the Sorites, and the interaction of vague predicates with three different forms of negation.

Aristotle holds that individual substances are ontologically independent from nonsubstances and universal substances but that non-substances and universal substances are ontologically dependent on substances. There is then an asymmetry between individual substances and other kinds of beings with respect to ontological dependence. Under what could plausibly be called the standard interpretation, the ontological independence ascribed to individual substances and denied of non-substances and universal substances is a capacity for independent existence. There is, however, a tension between this interpretation and the (...) asymmetry between individual substances and the other kinds of entities with respect to ontological independence. I will propose an alternative interpretation: to weaken the relevant notion of ontological independence from a capacity for independent existence to the independent possession of a certain ontological status.

Causal pluralists hold that that there is not just one determinate kind of causation. Some causal pluralists hold that ‘cause’ is ambiguous among these different kinds. For example, Hall (2004) argues that ‘cause’ is ambiguous between two causal relations, which he labels dependence and production. The view that ‘cause’ is ambiguous, however, wrongly predicts zeugmatic conjunction reduction, and wrongly predicts the behaviour of ellipsis in causal discourse. So ‘cause’ is not ambiguous. If we are to disentangle causal pluralism from the (...) ambiguity claim, we need to consider what other linguistic approaches are available to the causal pluralist. I consider and reject proposals that ‘cause’ is a general term, that the term is an indexical, and that the term conveys different kinds of causation through implicature or presupposition. Finally, I argue that causal pluralism is better handled by treating ‘cause’ as a univocal term within a dynamic interpretation framework. (shrink)

This paper examines and analyzes five definitions of ‘existential risk.’ It tentatively adopts a pluralistic approach according to which the definition that scholars employ should depend upon the particular context of use. More specifically, the notion that existential risks are ‘risks of human extinction or civilizational collapse’ is best when communicating with the public, whereas equating existential risks with a ‘significant loss of expected value’ may be the most effective definition for establishing existential risk studies as a legitimate field of (...) scientific and philosophical inquiry. In making these arguments, the present paper hopes to provide a modicum of clarity to foundational issues relating to the central concept of arguably the most important discussion of our times.

This paper examines Wesley Salmon's "process" theory of causality, arguing in particular that there are four areas of inadequacy. These are that the theory is circular, that it is too vague at a crucial point, that statistical forks do not serve their intended purpose, and that Salmon has not adequately demonstrated that the theory avoids Hume's strictures about "hidden powers". A new theory is suggested, based on "conserved quantities", which fulfills Salmon's broad objectives, and which avoids the problems discussed.

Discussion of the Aristotelian syllogistic over the last sixty years has arguably centered on the question whether syllogisms are inferences or implications. But the significance of this debate at times has been taken to concern whether the syllogistic is a logic or a theory, and how it ought to be represented by modern systems. Largely missing from this discussion has been a study of the few passages in the Prior Analytics where Aristotle provides explicit guidance on how to individuate syllogisms. (...) I argue that syllogisms are individuated by unordered premise pairs and so may be fruitfully thought of as multi-succedent sequents. I conclude by drawing a few consequences for the representation of the syllogistic. (shrink)

Is there grounding in ancient philosophy? To ask a related but different question: is grounding a useful tool for the scholar of ancient philosophy? These questions are difficult, and my goal in this paper is not so much to give definitive answers as to clarify the questions. I hope to direct the student of contemporary metaphysics towards passages where it may be fruitful to look for historical precedent. But I also hope to offer the student of ancient philosophy some guidance (...) on when drawing on the contemporary discussion of grounding may be beneficial. (shrink)

The relation of ontological dependence or grounding, expressed by the terminology of separation and priority in substance, plays a central role in Aristotle’s Categories, Metaphysics, De Anima and elsewhere. The article discusses three current interpretations of this terminology. These are drawn along the lines of, respectively, modal-existential ontological dependence, essential ontological dependence, and grounding or metaphysical explanation. I provide an opinionated introduction to the topic, raising the main interpretative questions, laying out a few of the exegetical and philosophical options that (...) influence one’s reading, and locating questions of Aristotle scholarship within the discussion of ontological dependence and grounding in contemporary metaphysics.

There is, no doubt, a temptation to treat preventions, such as ‘the father’s grabbing the child prevented the accident’, and cases of ‘causation’ by omission, such as ‘the father’s inattention was the cause of the child’s accident’, as cases of genuine causation. I think they are not, and in this paper I defend a theory of what they are. More specifically, the counterfactual theory defended here is that a claim about prevention or ‘causation’ by omission should be understood not as (...) being directly about actual genuine causation but primarily as a counterfactual claim about genuine causation.1 The relation between actual causation and the mere possibility of causation allows my theory to explain both the difference and the similarity between the two notions (causation and prevention/omission). Further, the difference explains certain intuitions we have and the similarity justifies and explains the fact that for practical purposes we usually treat preventions and omissions as if they were genuine causation. Finally, the fact that this counterfactual theory of prevention and omission takes causation as primitive suggests that it is consistent with any theory of causation. This allows us to construct two arguments against what I will call genuinism, the view that cases of prevention and ‘causation’ by omission really are cases of genuine causation. In section II I show that genuinism does not account for the so-called intuition of difference. In section III I outline a number of problems that various theories of causation have with preventions and ‘causation’ by omission. These problems are ipso facto problems for genuinism, whereas I show in section V how the counterfactual theory solves those problems. Further, I answer a genuinist argument based on another type of intuition—the genuinist intuition—by showing why we have that intuition and how it should be handled (section VI). (shrink)

Both literalism, the view that mathematical objects simply exist in the empirical world, and fictionalism, the view that mathematical objects do not exist but are rather harmless fictions, have been both ascribed to Aristotle. The ascription of literalism to Aristotle, however, commits Aristotle to the unattractive view that mathematics studies but a small fragment of the physical world; and there is evidence that Aristotle would deny the literalist position that mathematical objects are perceivable. The ascription of fictionalism also faces a (...) difficult challenge: there is evidence that Aristotle would deny the fictionalist position that mathematics is false. I argue that, in Aristotle's view, the fiction of mathematics is not to treat what does not exist as if existing but to treat mathematical objects with an ontological status they lack. This form of fictionalism is consistent with holding that mathematics is true. (shrink)

Individual substances are the ground of Aristotle’s ontology. Taking a liberal approach to existence, Aristotle accepts among existents entities in such categories other than substance as quality, quantity and relation; and, within each category, individuals and universals. As I will argue, individual substances are ontologically independent from all these other entities, while all other entities are ontologically dependent on individual substances. The association of substance with independence has a long history and several contemporary metaphysicians have pursued the connection. In this (...) chapter, I will discuss the intersection of these notions of substance and ontological dependence in Aristotle. I will canvass a few contemporary formulations of ontological dependence and discuss some of the interpretative difficulties in ascribing any of these formulations to Aristotle’s characterization of individual substances as ontologically independent. My aim is not to resolve fully these difficulties but to locate the topics of substance and independence relative to certain other controversies in Aristotle studies. However, I will sketch a position. In particular, elsewhere I have speculated that Aristotle is both a primitivist and a pluralist with respect to ontological dependence, and I will develop this line of interpretation a bit further later in the chapter.

Gordon Baker in his last decade published a series of papers (now collected inBaker 2004), which are revolutionary in their proposals for understanding of later Wittgenstein. Taking our lead from the first of those papers, on “perspicuous presentations,” we offer new criticisms of ‘elucidatory’ readers of later Wittgenstein, such as Peter Hacker: we argue that their readings fail to connect with the radically therapeutic intent of the ‘perspicuous presentation’ concept, as an achievement‐term, rather than a kind of ‘objective’ mapping of (...) a ‘conceptual landscape.’Baker's Wittgenstein, far from being a ‘language policeman’ of the kind that often fails to influence mainstream philosophy, offers an alternative to the latent scientism of Wittgenstein's influential ‘elucidatory’ readers.

Changing patterns of political participation observed by political scientists over the past half-century undermine traditional democratic theory and practice. The vast majority of democratic theory, and deliberative democratic theory in particular, either implicitly or explicitly assumes the need for widespread citizen participation. It requires that all citizens possess the opportunity to participate and also that they take up this opportunity. But empirical evidence gathered over the past half-century strongly suggests that many citizens do not have a meaningful opportunity to participate (...) in the ways that many democratic theorists require, and do not participate in anything like the numbers that they believe is necessary. This paper outlines some of the profound changes that have been experienced by liberal democratic states in the 20th and early 21st Centuries, changes which are still ongoing, and which have resulted in declines in citizens participation and trust, the marginalisation of citizens from democratic life, and the entrenchment of social and economic inequalities which have damaged democracy. The paper challenges the conventional wisdom in rejecting the idea that the future of democracy lies in encouraging more widespread participation. The paper takes seriously the failure of the strategies adopted by many states to increase participation, especially among the poor, and suggests that instead of requiring more of citizens, we should in fact be requiring less of them. Instead of seeking to encourage more citizen participation, we should acknowledge that citizens will probably not participate in the volume, or in the ways, many democratic theorists would like, and that therefore we need an alternative approach: a regime which can continue to produce democratic outcomes, and which satisfies the requirements of political equality, in the absence of widespread participation by citizens.

1 Context The idea for the current issue of _Philosophia Scientiæ_ emerged from discussions which took place in the Manchester Ethnomethodology Reading Group. This reading group has its origins in Wes Sharrock’s weekly discussion groups, which have taken place in Manchester (UK) since the early 1970s. As the global Covid-19 pandemic hit in early 2020, the reading group moved online, facilitated by Phil Hutchinson and Alex Holder. Being an online reading group opened up participation to people beyond Northwest UK and (...) within weeks the group became global, with the membership including participants logging on from Canada, Czech Republic, Finland, France, Germany, Greece, Hong Kong, Japan, Macau, New Zealand, Spain, Sweden, and the USA.

Although diagnosis is integral to the theory and practice of psychiatry, social scientists have not developed a comprehensive approach to diagnosis. This paper presents a preliminary outline of the issues which a sociology of diagnosis should integrate. These include bias and social control in psychiatric diagnosis, diagnosis as part of a new extension of the biopsychiatric medical model, and flaws in contemporary diagnostic categorization. These issues are then viewed in terms of professional practice styles, diagnostic biases, psychiatry's professional dominance over (...) the mental health field, and psychiatric hegemony over the clinical interaction with patients.

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the (...) view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals. (shrink)

According to Hugh Mellor in Real Time II, assuming the logical independence of causal facts and the ‘law of large numbers’, causal loops are impossible because if they were possible they would produce inconsistent sets of frequencies. I clarify the argument, and argue that it would be preferable to abandon the relevant independence assumption in the case of causal loops.

When Aristotle introduces the perfect moods, he refers back to the dictum de omni et nullo, a semantic condition for universal affirmations and negations. There recently has been renewed interest in the question whether the dictum validates the assertoric syllogistic. I rehearse evidence that Aristotle provides a mereological semantics for universal affirmations and negations, and note that this semantics entails a nonstandard reading of the dictum, under which the dictum, in the presence of a minimal logical apparatus, indeed validates the (...) assertoric syllogistic. I argue that this mereological validation offers advantages over recent discussions in Morison, Malink, Ebert and Vlasits. (shrink)
