1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

What kind of knowledge is medical knowledge? Can medicine be explained scientifically? Is disease a scientific concept, or do explanations of disease depend on values? What is ‘evidence-based’ medicine? Are advances in neuroscience bringing us closer to a scientific understanding of the mind? The nature of medicine raises fundamental questions about explanation, causation, knowledge and ontology – questions that are central to philosophy as well as medicine. In this book Paul R. Thompson and Ross E. G. Upshur introduce (...) the fundamental issues in philosophy of medicine for those coming to the subject for the first time. They introduce and explain the following key topics: Understanding the physician-patient relationship: the phenomenology of the medical encounter. Models and theories in biology and medicine: what role do theories play in medicine? Are they similar to scientific theories? Randomised controlled trials: can scientific experiments be replicated in clinical medicine? What are the philosophical criticisms levelled at RCTs? The concept of evidence in medical research: what do we mean by ‘Evidence-based medicine?’ Should all medicine be based on evidence? Causation in medicine What do advances in neuroscience reveal about the relationship between mind and body? Defining health and disease: are explanations of disease objective or do they depend on values? Evolutionary medicine: what is the role of evolutionary biology in understanding medicine? Is it relevant? Extensive use of empirical examples and case studies is made throughout the book. These include debates about smoking and cancer, the use of placebos in randomised controlled trials and controversies about research into the causes of HIV and autism. This is an indispendable introduction to those teaching philosophy of medicine and philosophy of science. (shrink)

Histone post‐translational modifications (PTMs) alter the chromatin architecture, generating “open” and “closed” states, and these structural changes can modulate gene expression under specific cellular conditions. While methylation and acetylation are the best‐characterized histone PTMs, citrullination by the protein arginine deiminases (PADs) represents another important player in this process. In addition to “fine tuning” chromatin structure at specific loci, histone citrullination can also promote rapid global chromatin decondensation during the formation of extracellular traps (ETs) in immune cells. Recent studies now show (...) that PAD4‐mediated citrullination of histone H1 at promoter elements can also promote localized chromatin decondensation in stem cells, thus regulating the pluripotent state. These observations suggest that PAD‐mediated histone deimination profoundly affects chromatin structure, possibly above and beyond that of other PTMs. Additionally, these recent findings further enhance our understanding of PAD biology and the important contributions that these enzymes play in development, health, and disease.

Humans have been modifying plants and animals for millennia. The dawn of molecular genetics, however, has kindled intense public scrutiny and controversy. Crops, and the food products which include them, have dominated molecular modification in agriculture. Organisations have made unsubstantiated claims and scare mongering is common. In this textbook Paul Thompson presents a clear account of the significant issues - identifying harms and benefits, analysing and managing risk - which lie beneath the cacophony of public controversy. His comprehensive (...) analysis looks especially at genetically modified organisms, and includes an explanation of the scientific background, an analysis of ideological objections, a discussion of legal and ethical concerns, a suggested alternative - organic agriculture - and an examination of the controversy's impact on sub-Saharan African countries. His book will be of interest to students and other readers in philosophy, biology, biotechnology and public policy. (shrink)

Recent interest in the evolution of the social contract is extended by providing a throughly naturalistic, evolutionary account of the biological underpinnings of a social contract theory of morality. This social contract theory of morality provides an evolutionary justification of the primacy of a moral principle of maximisation of the opportunities for evolutionary reproductive success, where maximising opportunities does not entail an obligation on individuals to choose to maximise their ERS. From that primary principle, the moral principles of inclusion, individual (...) sovereignty and equality can be derived. The implications of these principles, within contractevolism, are explored through an examination of patriarchy, individual sovereignty and copulatory choices, and overpopulation and extinction. Contractevolism is grounded in evolutionary dynamics that resulted in humans and human societies. The most important behavioural consequences of evolution to contractevolism are reciprocity, cooperation, empathy, and the most important cognitive consequences are reason and behavioural modification.

Evolution - both the fact that it occurred and the theory describing the mechanisms by which it occurred - is an intrinsic and central component in modern biology. Theodosius Dobzhansky captures this well in the much-quoted title of his 1973 paper 'Nothing in biology makes sense except in the light of evolution'. The correctness of this assertion is even more obvious today: philosophers of biology and biologists agree that the fact of evolution is undeniable and that the theory of evolution (...) explains that fact. Such a theory has far-reaching implications. In this volume, eleven distinguished scholars address the conceptual, metaphysical and epistemological richness of the theory and its ethical and religious impact, exploring topics including DNA barcoding, three grand challenges of human evolution, functionalism, historicity, design, evolution and development, and religion and secular humanism. The volume will be of great interest to those studying philosophy of biology and evolutionary biology. (shrink)

Rolf Gruner has argued that natural selection plus time does not entail, and hence does not explain, evolution. This according to Gruner is the result of the undeniable fact that evolution involves an increase in the complexity of organisms:Since increase in complexity is part of the concept of evolution, evolution is not explained by the theory of natural selection. The Darwinian or Neo-Darwinian affirms the reality of evolution and seems to believe that it can be accounted for in terms of (...) natural selection. But it could be accounted for in this way only if the assumption were justified that generally the more complex organism is better adapted to its environment, and thus stands a better chance to survive and breed, than the less complex organism. And this assumption is not justified. “The more complex, the better adapted” will not do even as a rule of thumb, as most biologists today will be prepared to admit. (shrink)

Among the numerous criticisms of sociobiology is the criticism that it is not genuine science. This paper defends sociobiology against this criticism. There are three aspects to the defense. First, it is argued that the testability criterion of pseudoscience is generally problematic as a criterion and that even if accepted it fails to mark sociobiology as a pseudoscience. Second, it is argued that Thagard's more comprehensive and sophisticated criterion of pseudoscience fails to mark sociobiology as a pseudoscience. Third, a positive (...) case for accepting sociobiology as genuine science is presented. (shrink)

Medical explanations of socially maladaptive behaviors most often involve an appeal to neuro-physiological models. One consequence of the appeal to such models is a lack of attention to the social character of the behaviors. It is, I argue, the social character of the behaviors that, even accepting a neuro-physiological etiology, makes classification and, hence, explanation of these disorders controversial and suspect. At the heart of the problem is the difficulty, resulting from the social aspects of the disorder, in fulfilling the (...) logical conditions of the analogical arguments employed in the explanations. The theoretical points of the paper are illustrated by a discussion of hyperactivity. CiteULike Connotea Del.icio.us What's this? (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

An environmental, climate mitigation rationale for research and development on liquid transportation fuels derived from plants emerged among many scientists and engineers during the last decade. However, between 2006 and 2010, this climate ethic for pursuing biofuel became politically entangled and conceptually confused with rationales for encouraging greater use of plant-based ethanol that were both unconnected to climate ethics and potentially in conflict with the value-commitments providing a mitigation-oriented reason to promote and develop new and expanded sources of biofuel. I (...) argue that the conceptual construct of technological trajectories provides a fecund approach to the ethical evaluation of R&D strategies in the case of plant-based liquid transportation fuels. The idea of a trajectory has a current use in the literature of science studies and aptly summarizes a number of themes that are critical to the evaluation of tools and techniques whose future shape, design, applications and potential consequences are necessarily somewhat speculative. In the case of biofuels, it is the imagined future trajectory that provides the basis for resistance to an emerging technology, rather than the present-day technical capabilities and the unexpected consequences of biofuel development.

This book explores historical and current discussions of the relevance of evolutionary theory to ethics. The historical section conveys the intellectual struggle that took place within the framework of Darwinism from its inception up to the work of G. C. Williams, W. D. Hamilton, R. D. Alexander, A. L. Trivers, E. O. Wilson, R. Dawkins, and others. The contemporary section discusses ethics within the framework of evolutionary theory as enriched by the works of biologists such as those mentioned above. The (...) issue of whether ethical practice and ethical theory can be grounded in the theory of evolution has taken a new and significant direction within the context of sociobiology and is proving to be a challenge to previous thinking. This book conveys that challenge. (shrink)

Scrutiny (1932-1953) was one of the most important critical reviews of the last century. Its editors and contributors included F. R. Leavis, Q. D. Leavis, Denys Thompson, L. C. Knights, D. W. Harding, W. H. Mellers, H. A. Mason, among others. In recasting Scrutiny’s critique of mass culture by way of Alisdair MacIntyre’s After Virtue (1981), I hope to show that the Scrutiny project not only dramatizes the conflicts internal to what MacIntyre calls emotivist culture, but provides a new (...) way of looking at the group’s relation to the culture industry, its purported elitism, and its deep ties with a communitarian rather than socialist politics.

The term “ideology” can cover almost any set of ideas, but its power to bewitch political activists results from its strange logic. It is part philosophy, part science, and part spiritual revelation, all tied together in leading to a remarkable paradox—that the modern Western world, beneath its liberal appearance, is actually the most systematically oppressive system of despotism the world has ever seen. In Alien Powers, Kenneth Minogue takes this complex intellectual construction apart, analyzing its logical, rhetorical, and psychological devices, (...) and thus opening it up to critical analysis. This new, ISI Books’ Background edition of Alien Powers includes a new introduction to the text by Martyn P. Thompson and critical essays on the text by political theorist Paul Gottfried and philosopher Stephen A. Erickson. (shrink)

This study investigates how patterns of media use and exposure to media messages are related to attitudes about artificial intelligence (AI) image generators. In doing so, it builds on theoretical accounts of media framing and public opinion about science and technology topics, including AI. The analyses draw on data from a survey of the US public (N = 1,035) that included an experimental manipulation of exposure to tweets framing AI image generators in terms of real art, artists’ concerns, artists’ outrage, (...) or competing interpretations. The results show that technology news use and science fiction viewing predicted support for AI art but also predicted belief that AI image generators will take jobs and steal art styles from human artists. In addition, the experimental results demonstrate that exposure to specific media messages can influence these responses. The findings carry implications for understanding the future adoption, use, and regulation of AI image generators. (shrink)

There have been a number of attempts to apply mechanism-related concepts to the notion of extended cognition. Such accounts appeal to the idea that extended cognitive routines are realized by mechanisms that transcend some salient border or boundary. The present paper describes some of the challenges confronting the effort to develop a mechanistic account of extended cognition. In particular, it describes five problems that must be resolved if we are to make sense of the idea that extended cognition can be (...) understood via an appeal to extended mechanisms. These problems are intended to guide the philosophical effort to develop a mechanistic account of extended cognition. (shrink)

Invited book review of R. P. Thompson, A remarkable journey: The story of evolution (Reaktion Books, 2015).

This chapter explores the notion of the Web‐extended mind, which is the idea that the technological and informational elements of the Web can sometimes serve as part of the mechanistic substrate that realizes human mental states and processes. It is argued that while current forms of the Web may not be particularly suited to the realization of Web‐extended minds, new forms of user interaction technology as well as new approaches to information representation do provide promising new opportunities for Web‐based forms (...) of cognitive extension. In addition, it is suggested that extended cognitive systems often rely on the emergence of social practices and conventions that shape how a technology is used. Web‐extended minds may thus depend on forms of socio‐technical co‐evolution in which social forces and factors play just as important a role as do the processes of technology design and development.

This chapter reviews the aspects of Mencius that did and did not interest Han-dynasty writers. With the help of digital concordances, it is easy to discover that many of the passages considered crucial today were rarely, if ever, cited in the Han. These include the parable of the infant about to fall into a well (2A.6), the debate with a Mohist named Yi Zhi 夷之 (3A.5), and the concept of liangzhi 良知 (7A.15), which, since Wang Yangming 王陽明 (1472–1528), has been (...) considered a cornerstone of Mencian ethics. The chapter discusses other key passages that are never mentioned in Han sources. Absence of evidence is not evidence of absence, and thus one cannot simply infer that these passages were unknown in the Han dynasty, but it remains significant that they were not regarded as essential to understanding Mencius’s philosophy. The conclusion will explore the differences between Mencius’s reception in the Han dynasty and his Neo-Confucianized reception today. (shrink)

According to the presentist, only the present moment exists and, as time passes, what’s present changes. However some argue that, if only one moment exists, the presentist cannot explain the passage of time. While the presentist historically appeals to surrogates—proxies which exist in the present but play the role of non-existent past times—to evade this sort of worry, the appeal to surrogates has come under renewed attack from Lisa Leininger. But hope is not lost for the presentist. I argue that (...) presentists do have the resources available to address the underlying issue Leininger articulates. Moreover, there’s disagreement amongst presentists about which version of presentism is best. For instance, David Ingram has recently argued that thisness presentism is preferable to other versions of presentism because it’s able to handle certain problems other versions of presentism cannot. However, I argue that this assessment is premature. More specifically, I argue that Ingram’s response to an objection from Lisa Leininger fails to address the core issue she raises. Consequently, I argue that presentists shouldn’t embrace thisness presentism just yet. In this way, my aims here are to: sharpen Leininger’s objection, highlight tenable presentist replies to it, and advance the discussion about which version of presentism should be favoured. (shrink)

As gene editing technologies such as CRISPR have become increasingly prominent, so have media portrayals of them. With this in mind, the present study builds on theoretical accounts of framing effects, cultivation effects, and genre-specific viewing effects to examine how different forms of media use predict attitudes toward applications of gene editing. Specifically, the study tests how news use, overall television viewing, and science fiction viewing are related to such attitudes. The analyses draw on original data from two surveys of (...) the U.S. public, one conducted in 2020 and the other in 2021. The results from both surveys indicate that news use and overall television viewing predict support for uses of gene editing, whereas science fiction viewing is not significantly related to opinion. The findings suggest that media frames and images may carry implications for the trajectory of public opinion about gene editing technologies and, ultimately, the social context for their development and adoption.

In Pagans & Christians in the City, Steven D. Smith argues that in contrast to ancient Rome, ancient Christianity, following Judaism, located the sacred outside the world, desacralizing the cosmos and everything in it—including the political order. It thereby introduced a political dualism and potentially contending allegiances. Although Smith’s argument is right so far as it goes, it underplays the role of Christianity’s immanent dimension in subverting the Roman empire and the sacral pattern of antiquity. This division of authority not (...) only undermined the Roman empire and antique sacral political order more generally—it also subverts the modern state, which, in the work of Hobbes and Rousseau, sought to remarry what Western Christianity divorced.

Many scholars view political contractarianism as a distinctly modern account of the foundations of political order. Ideas such as popular sovereignty, the right of revolution, the necessity of the consent of the governed for rightful political authority, natural equality, and a pre-civil state of nature embody the modern rupture with classical political philosophy and traditional Christian theology. At the headwaters of this modern revolution stands Thomas Hobbes. Since the American founders subscribed to the social contract theory, they are often said (...) to reject classical political philosophy and traditional Christian political theology as well. In America on Trial, Robert Reilly rejects the usual argument. He maintains that the building blocks of the American founding originate in medieval Christian political theology. In this essay, I argue that a morally and metaphysically realist contractarian tradition—one that affirms natural equality, the authority of the society over government, the necessity of consent for legitimate government, the right to resist tyrannical rulers, and the idea of a pre-civil state of nature—predates Hobbes and also that the voluntarist contractarian tradition inaugurated by Hobbes is self-referentially incoherent. A coherent political contractarianism logicially depends on the sort of metaphysics and moral ontology Hobbes rejects. (shrink)

__Augustine and the Cure of Souls __situates Augustine within the ancient philosophical tradition of using words to order emotions. Paul Kolbet uncovers a profound continuity in Augustine's thought, from his earliest pre-baptismal writings to his final acts as bishop, revealing a man deeply indebted to the Roman past and yet distinctly Christian. Rather than supplanting his classical learning, Augustine's Christianity reinvigorated precisely those elements of Roman wisdom that he believed were slipping into decadence. In particular, Kolbet addresses the manner (...) in which Augustine not only used classical rhetorical theory to express his theological vision, but also infused it with theological content. This book offers a fresh reading of Augustine's writings--particularly his numerous, though often neglected, sermons--and provides an accessible point of entry into the great North African bishop's life and thought. "For someone who does not know Augustine well this book will be an excellent introduction to his thought from an absolutely crucial viewpoint. Augustine's preaching, teaching, and attempts to reach the minds and hearts of his congregation have been largely overlooked. This book has the great virtue of demonstrating why these were important." --_Carol Harrison, Durham Universi_ty "In this insightful and lucid study Kolbet leads his readers across the boundaries of ancient philosophy, psychology, rhetoric, and theology. He examines the ancient practice of the 'cure of the soul' and charts its Christian appropriation by Augustine. The volume offers its own medicinal promise--the reordering of our contemporary understanding of early Christianity and its complex association with classical culture." --_John Peter Kenney, St. Michael's College_.

Architecture has become an important discourse for new expressions of post-national identity in general and in particular for the emergence of a `spatial' European identity. No longer tied to the state to the same degree as in the period of nation-building, architecture has become a significant cultural expression of post-national identities within and beyond the nation-state. The article looks at four such discourses, first, taking the Millennium Dome in London and the Reichstag in Berlin, we show that architecture can express (...) in a reflexive way contested and ambiguous national identities; second, the case of architecture in post-communist European societies illustrates the dual identity of architecture as a project of building and of re-building; third, the EU's search for a cultural form is discussed with respect to the architectural designs on the Euro banknotes; and finally the question of architecture as a relation to a lived space is considered with regard to cityscapes as yet another expression of a tendentially spatialized European identity.

Most scholars who write on social contract and classical natural law perceive an irreconcilable tension between them. Social contract theory is widely considered the political-theoretic concomitant of modern philosophy. Against the regnant view, The Social Contract in the Ruins, argues that all attempts to ground political authority and obligation in agreement alone are logically self-defeating. Political authority and obligation require an antecedent moral ground. But this moral ground cannot be constructed by human agreement or created by sheer will-human or divine. (...) All accounts of morality as constructed or made collapse into self-referential incoherence. Only an uncreated, real good can coherently ground political authority and obligation or the proposition that rightful government depends on the consent of the governed. Government by consent requires classical natural law for its very coherence. (shrink)

Nietzsche’s conception of eros and its role in the development of philosophers is similar to the conception of those same topics espoused by Diotima in Plato’s Symposium. Nietzsche and Diotima agree that eros is an insatiable desire to possess the beautiful, that eros aims at immortality through reproduction, and that philosophy requires an ascent beyond sexual desire to “higher” forms of eros, which nevertheless are still modeled on heterosexual reproduction. Understanding these facets of Nietzsche’s view leads to an apparent contradiction (...) in that Nietzsche thinks of philosophy on the model of reproduction and ascribes to the philosopher both the female and the male roles in heterosexual reproduction. I argue that this ambivalence reflects Nietzsche’s view that practicing philosophy requires balancing two conflicting philosophical tendencies: on the one hand, pursuit of truth, which involves dissatisfaction with oneself; on the other hand, creation, which involves acknowledgment of one’s own capacity and value.

Social machines are a prominent focus of attention for those who work in the field of Web and Internet science. Although a number of online systems have been described as social machines, there is, as yet, little consensus as to the precise meaning of the term “social machine.” This presents a problem for the scientific study of social machines, especially when it comes to the provision of a theoretical framework that directs, informs, and explicates the scientific and engineering activities of (...) the social machine community. The present paper outlines an approach to understanding social machines that draws on recent work in the philosophy of science, especially work in so-called mechanical philosophy. This is what might be called a mechanistic view of social machines. According to this view, social machines are systems whose phenomena are explained via an appeal to socio-technical mechanisms. We show how this account is able to accommodate a number of existing attempts to define the social machine concept, thereby yielding an important opportunity for theoretical integration. (shrink)

This book is the authorized political biography of Kenneth Waltz. The theoretical work of Kenneth Neal Waltz (June 8, 1924 - May 12, 2013) during the last half of the twentieth century in international relations theory is known by virtually everyone in this scholarly field. He is among the few likely still to be cited in the last half of the twenty-first century. Then, as now, he no doubt has followers within the realist camp who see him as an earlier (...) luminary as well as his critics drawn to the lightning-rod quality of his work. Paul Viotti identifies the intellectual sources and experiences leading to the ideas that underlie Waltz's theoretical work. Viotti has been granted unfettered access to Waltz's files at Columbia, in his residences in Manhattan and Maine, and in archives at Oberlin, and uses these documents to paint a thorough, insightful biography bolstered by some of Waltz's previously-unexplored work. Through a series of interviews with Waltz about his life-starting with his German great-grandparents' immigration to the US in the 19th century-this biography produces personal insights into the development of his theoretical and policy-based contributions.
