Katz denies that organisms created in a lab as part of a de-extinction attempt will be authentic members of the extinct species, on the basis that they will lack the original species’ defining biological and evolutionary history. Against Katz, I note that an evolutionary lineage is conferred on an organism through its inheriting genes from forebears already possessed of such a lineage, and that de-extinction amounts to a delayed, human-assisted reproductive process, in which genes are inherited from forebears long dead. (...) My conclusion is that de-extinct organisms can perfectly well have an ancient evolutionary history, contrary to what Katz claims. (shrink)

This paper considers the use that Plato makes of the Principle of Non-Contradiction in his engagements with eristic refutations. By examining Plato’s use of the principle in his most detailed engagements with eristic—in the Sophist, the discussion of “agonistic” argumentation in the Theaetetus, and especially the Euthydemus—I aim to show that the pressure exerted on Plato by eristic refutations played a crucial role in his development of the PNC, and that the principle provided him with a much more sophisticated means (...) of demarcating philosophical argumentation from eristic than he is generally thought to have. In particular, I argue that Plato’s qualified formulation of the PNC restricts the class of genuine contradictions in such a way that reveals the contradictions that eristics produce through their refutations to be merely apparent and that Plato consistently appeals to his qualified conception of genuine contradiction in his encounters with eristics in order to demonstrate that their refutations are merely apparent. The paper concludes by suggesting that the conception of genuine contradiction afforded by the PNC did not just provide Plato with a way of demarcating genuine from eristic refutations, but also with an answer to substantive philosophical challenges that eristics raised through their refutations.

Abstract:In this paper, I evaluate the possibility of convergence between animal welfare and environmental ethics. By surveying the most prominent views within each of these respective camps, I argue that animal welfare ethics and ecological theories in environmental ethics are incommensurable in virtue of their respective individualistic and holistic value theories. I conclude by arguing that this conceptual clarification allows us to see that animal welfare ethics can nevertheless be made commensurable with theories in environmental ethics according to which value (...) primarily resides in individuals, rather than in collectives and communities.

The counterfactual account of physical computation is simple and, for the most part, very attractive. However, it is usually thought to trivialize the notion of physical computation insofar as it implies ‘limited pancomputationalism’, this being the doctrine that every deterministic physical system computes some function. Should we bite the bullet and accept limited pancomputationalism, or reject the counterfactual account as untenable? Jack Copeland would have us do neither of the above. He attempts to thread a path between the two horns (...) of the dilemma by buttressing the counterfactual account with extra conditions intended to block certain classes of deterministic physical systems from qualifying as physical computers. His theory is called the ‘algorithm execution account’. Here we show that the algorithm execution account entails limited pancomputationalism, despite Copeland’s argument to the contrary. We suggest, partly on this basis, that the counterfactual account should be accepted as it stands, pancomputationalist warts and all. (shrink)

In European culture the sacred and the secular have existed in a dialectical relationship. Prodi sees the fifteenth-century crisis of Christianity as opening up three paths that eroded this dualism and tended towards modernity: civic-republican religion, sacred monarchy, and the territorial churches. Important counter-forces, which sought to maintain dualism, included the Roman-Tridentine Compromise, and those forms of Radical Christianity which rejected confessionalisation outright. During the Eighteenth Century, all these phenomena tended to contribute to one of two tendencies: towards civic religion, (...) or towards political religion. The former preserved a distinction between conscience and law; the latter comprised a state religion which sought to perfect all of human nature. It was civic religion which become embodied in the early USA, alienating God from worldly power, but leaving him as the guarantor of agreements between humans. Back in Europe, Prodi tracks the relationship between the Catholic Church and the new national states. He then turns to the political religions of the Twentieth Century. Prodi concludes by emphasising that this dualism of sacred and secular power lay at the centre of Western modernity, and expresses his fears about the collapse of civic religion into political religion, especially in the USA.

This book is about the philosophy of de-extinction. -/- CHAPTER 1 introduces the two main philosophical questions that are raised by the prospect of extinct species being brought back from the dead—namely, the ‘Authenticity Question’ and the ‘Ethical Question’. It distinguishes the many different types and methods of de-extinction. Finally, it examines the aims of wildlife conservation with a view to whether they are compatible with de-extinction, or not. -/- CHAPTER 2 examines three prime candidates for de-extinction—namely, the aurochs, the (...) woolly mammoth, and the passenger pigeon. It is about what these animals were like, why people want to resurrect them, and the methods by which their resurrections could be accomplished. -/- CHAPTER 3 is about the authenticity of de-extinct animals. Critics of de-extinction have offered many reasons for thinking that the products of de-extinction will be inauthentic. The bulk of the chapter is taken up with surveying their arguments. We attempt to show that none are convincing, and end the chapter by offering and defending two arguments in favour of the view that authentic de-extinctions are possible. -/- CHAPTER 4 surveys and critically evaluates all the main arguments both for and against de-extinction. It presents a qualified defence of the claim that conservationists should embrace de-extinction. It ends with a list of do’s and don’ts for conservationist de-extinction projects. (shrink)

David Lewis describes, then attempts to refute, a simple anti-Humean theory of desire he calls ‘Desire as Belief’. Lewis’ critics generally accept that his argument is sound and focus instead on trying to show that its implications are less severe than appearances suggest. In this paper I argue that Lewis’ argument is unsound. I show that it rests on an essential assumption that can be straightforwardly proven false using ideas and principles to which Lewis is himself committed.

This paper concerns the three great modal dichotomies: (i) the necessary/contingent dichotomy; (ii) the a priori/empirical dichotomy; and (iii) the analytic/synthetic dichotomy. These can be combined to produce a tri-dichotomy of eight modal categories. The question as to which of the eight categories house statements and which do not is a pivotal battleground in the history of analytic philosophy, with key protagonists including Descartes, Hume, Kant, Kripke, Putnam and Kaplan. All parties to the debate have accepted that some categories are (...) void. This paper defends the contrary view that all eight categories house statements—a position I dub ‘octopropositionalism’. Examples of statements belonging to all eight categories are given. (shrink)

THIS PAPER CONCERNS A CONTROVERSY about priorities between J. D. Forbes, Professor of Natural Philosophy at the University of Edinburgh, and the noted Swiss scientist Louis Agassiz, later to be a distinguished teacher at Harvard. Its origins lie in the visit which Forbes made at Agassiz' invitation to the Unteraar glacier in Switzerland, in the summer of 1841, during which a major topic of interest was their observations of the bandes bleues, markings in the ice previously little discussed. Both men, (...) in independent later publications, were to establish the importance of the bandes in the theory of glacial ice and its movement. The question of credit for the discovery, and priority in its publication, was unclear at the time and has remained so despite bitter debate. Examination of surviving papers in Great Britain and in Switzerland suggests that previous discussions have not closed the question,' and our purpose is to review the evidence and if possible to clarify the issue.

Interpreters of Socrates’ argument at Gorgias 466A4-468E5 that rhetoricians and tyrants have little power because they do almost nothing they want tend either to think that the argument is invalid, or that Socrates relies upon peculiar uses of the terms ‘power’ and ‘want.’ By examining this passage within its larger dialectical context, I show that Socrates’ argument is valid and relies only on his interlocutor’s conventional use of the terms ‘power’ and ‘want.’.

Is the resurrection of an extinct species genuinely possible, or not? Will organisms produced by de-extinction technology be authentic new members of the species that died out, or just convincing fakes? We seek to answer these questions in this chapter. Critics of de-extinction have offered many reasons for thinking that the products of de-extinction will be inauthentic. The bulk of the chapter is taken up with surveying their arguments. We attempt to show that none are convincing. We end the chapter (...) by offering and defending two arguments in favour of the view that authentic de-extinctions are possible. (shrink)

Abstract:The History of Political Thought is a discipline which is very closely aligned with the Anglophone liberal political tradition. It has not, consequently, ever had very much to say about warfare. Richard Tuck's important research marks an exception in this field, but Tuck's work is marked by significant omissions. He defined Catholic scholasticism too narrowly, omitting the Franciscan followers of John Duns Scotus, and excluded Protestant scholasticism (except the work of Hugo Grotius) entirely from consideration. Remedying these omissions leaves us (...) with an early modern theorization of war that appears much less ripe for secularization than scholars have previously supposed. (shrink)

Abstract:Early modern Europeans organized important reflections on the nature of political society and the justice of warfare around their image of the American Indian. But Jewish parents and children, living in Europe at the mercy of Christian societies and states, also provided Europeans with the occasion to reflect on government and holy war. This article will describe the relevance of Christian theology to the experiences of one Roman Jewish family in the 1640s, before reviewing the place of forced baptism in (...) Scotist thinking on politics in Rome, and establishing the connection between these doctrines and holy war. (shrink)

Did early modern European states make themselves sacred? The historian Paolo Prodi insisted that they did, whereas for the philosopher Giorgio Agamben sacred and secular power were so indistinguishable that the question was moot. This group of articles seeks to explain and explore the approaches of these two accomplished Italian scholars to the problem of early modern sacralisation. This introduction reviews the context in which Prodi and Agamben worked, sketches brief biographies, and describes the arguments that they advanced which are (...) most relevant to early modern history. Their work emerged from the debate on secularisation in the German-speaking lands, the confessionalisation thesis as it was advanced by German historians of Reformation, Counter-Reformation, and Catholic Reform, and twentieth-century Catholic thought about the relationship between religion and totalitarian states. Both Prodi and Agamben belonged to traditions that sat at an angle to the liberalism that underpins historical and philosophical thought in the English-speaking world. (shrink)

The media are inextricable from controversy yet "controversy" is an under-theorized term in studies of the media, even though controversies over specific images, from "video nasties" to snapshots from Abu Ghraib, have structured our understanding of the media's power, seductiveness and dangers. This collection offers a series of case studies of recent media controversies and draws on new perspectives in cultural studies to consider a wide variety of types of image, including newspaper cartoons, advertising and fashion photography, music videos, photojournalism, (...) news media, art works, hardcore porn film, anime, horror and exploitation movies, video games, and YouTube reaction videos. In the current climate when images appear to be increasingly controversial, it is important that media controversies are not made the excuse for greater censorship and the demonization of "dangerous" images and the audiences that consume them. The case studies in this book suggest how we might achieve a more subtle understanding of controversial images and negotiate the difficult terrain of the new media landscape. (shrink)

The possibility of aesthetic objectivity is a standard topic within philosophical aesthetics and raises questions that have always been heavily disputed. ‘Endlos umstritten, ewig schön’ will readdress these issues through the most prominent concept within the philosophy of art, namely the concept of beauty, and ask the question: Can artworks be beautiful in themselves or is beauty a subjective reaction of the viewer? For artists since the beginning of the 20th century, the notion of beauty has been associated with frivolity, (...) consumerism and pure pleasure and as a result, challenged and rejected. Thus the term has been replaced in recent aesthetic debates by discourses such as relational aesthetics, art as social space, art as service and poetic knowledge. The exhibition, which will represent current artistic positions from the UK and Germany that challenge both classical and more contemporary conceptions of beauty, will provide the context for an interdisciplinary symposium. Art theorists and philosophers from varying aesthetic traditions have been invited to take part and to discuss the possible relevance beauty could have for the production and reception of contemporary art. In bringing dynamic artists, philosophers and theorists together, we hope to examine this old debate from new and invigorating perspectives. (shrink)

Less discussed than Hume’s skepticism about what grounds there could be for projecting empirical hypotheses is his concern with a skeptical regress that he thought threatened to extinguish any belief when we reflect that our reasoning is not perfect. The root of the problem is the fact that a reflection about our reasoning is itself a piece of reasoning. If each reflection is negative and undermining, does that not give us a diminution of our original belief to nothing? It requires (...) much attention to detail, we argue, to determine whether or not there is a skeptical problem in this neighborhood. Consider that if we subsequently doubt a doubt we had about our reasoning, that would suggest a restoration of some of the force of our original belief. We would then have instead of runaway skepticism an alternating sequence of pieces of skeptical reasoning that cancel each others’ effects on our justification in the original proposition, at least to some degree. We will argue that the outcome of the sequence of reflections Hume is imagining depends on information about a given case that is not known a priori. We conclude this from the fact that under three precise, explanatory, and viable contemporary reconstructions of what this kind of reasoning about reasoning could be like and how it has the potential to affect our original beliefs, a belief-extinguishing regress is not automatic or necessary.

In this book, Matthew Duncombe argues that Plato, Aristotle, certain Stoics, and Sextus Empiricus each held a broadly "constitutive" view of relativity. According to constitutive accounts, a "relative" is constituted by the relation that it bears to its "correlative". Such treatments of relativity sharply contrast with more familiar nonconstitutive accounts, according to which standing in some relation suffices for being a relative. On such a view, versions of which many scholars have assumed to be at work in antiquity, Alcibiades counts (...) as a relative because he is related to Socrates through the "is more beautiful than" relation.

This book brings together scholars from a variety of epistemological perspectives to explore the multiple ways in which sexuality does indeed matter in the arena of public education.

When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven‐ to ten‐year‐olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application. After rating the quality of an initial explanation, children could request and receive additional information or (...) return to the main menu to choose a new animal to explore. Consistent with past research, there were both developmental and IQ‐related differences in how children evaluated explanation quality. But across development, children were more likely to request additional information in response to circular explanations than mechanistic explanations. Importantly, children were also more likely to request additional information in direct response to explanations that they themselves had assigned low ratings, regardless of explanation type. In addition, there was significant variability in both children's explanation evaluation and their exploration, suggesting important directions for future research. The findings support the deprivation theory of curiosity and offer implications for education. (shrink)

In this comprehensive collection of essays, most of which appear for the first time, eminent scholars from many disciplines—philosophy, economics, sociology, political science, demography, theology, history, and social psychology—examine the causes, nature, and consequences of present-day consumption patterns in the United States and throughout the world.

Kant’s position on the problem of free will can be perplexing and frustrating: all the real questions about human agential capacities or even about issues of moral imputability are empirical questions, which have empirical answers. But there remains a metaphysical or transcendental problem about the possibility of freedom, which is forever insoluble. Ian Proops’ discussion in The Fiery Test of Critique is to be commended for displaying the rare virtue of appreciating this last point and presenting Kant’s position about it (...) accurately. The only questionable part has to do with the standard terminology – ‘determinism’, ‘libertarianism’, ‘compatibilism’, and ‘incompatibilism’. I argue that it would be better to say, as Kant does, and Proops also does most of the time, that practical freedom, hence transcendental freedom, must be presupposed whenever we act or even judge, but how freedom is possible is both unknowable and even incomprehensible to us.

Randomized controlled trial trial designs exist on an explanatory-pragmatic spectrum, depending on the degree to which a study aims to address a question of efficacy or effectiveness. As conceptualized by Schwartz and Lellouch in 1967, an explanatory approach to trial design emphasizes hypothesis testing about the mechanisms of action of treatments under ideal conditions, whereas a pragmatic approach emphasizes testing effectiveness of two or more available treatments in real-world conditions. Interest in, and the number of, pragmatic trials has grown substantially (...) in recent years, with increased recognition by funders and stakeholders worldwide of the need for credible evidence to inform clinical decision-making. This increase has been accompanied by the onset of learning healthcare systems, as well as an increasing focus on patient-oriented research. However, pragmatic trials have ethical challenges that have not yet been identified or adequately characterized. The present study aims to explore the views of key stakeholders with respect to ethical issues raised by the design and conduct of pragmatic trials. It is embedded within a large, four-year project that seeks to develop guidance for the ethical design and conduct of pragmatic trials. As a first step, this study will address important gaps in the current empirical literature with respect to identifying a comprehensive range of ethical issues arising from the design and conduct of pragmatic trials. By opening up a broad range of topics for consideration within our parallel ethical analysis, we will extend the current debate, which has largely emphasized issues of consent, to the range of ethical considerations that may flow from specific design choices. Semi-structured interviews with key stakeholders, across multiple jurisdictions, identified based on their known experience and/or expertise with pragmatic trials. We expect that the study outputs will be of interest to a wide range of knowledge users including trialists, ethicists, research ethics committees, journal editors, regulators, healthcare policymakers, research funders and patient groups. All publications will adhere to the Tri-Agency Open Access Policy on Publications. (shrink)

In this article, I explore the impact of disability on one of life’s goods: achievement. Contra Campbell, Nyholm, and Walter, I argue that construing the magnitude of achievements in terms of subjective effort trivializes what it means to achieve. This poses a problem for the authors’ argument that disability, in general, does not reduce access to this good. I draw on an alternative construal of achievement that I have proposed elsewhere in order to show that, indeed, many disabilities do (...) not restrict access to achievement. I defend this argument against an objection that it problematically relativizes the achievements of persons with disability, and I close with general lessons for future work. (shrink)
