Scientists often make surprising claims about things that no one can observe. In physics, chemistry, and molecular biology, scientists can at least experiment on those unobservable entities, but what about researchers in fields such as paleobiology and geology who study prehistory, where no such experimentation is possible? Do scientists discover facts about the distant past or do they, in some sense, make prehistory? In this book Derek Turner argues that this problem has surprising and important consequences for the scientific realism (...) debate. His discussion covers some of the main positions in philosophy of science - realism, social constructivism, empiricism, and the natural ontological attitude - and shows how they relate to issues in paleobiology and geology. His original and thought-provoking book will be of wide interest to philosophers and scientists alike. (shrink)

In the wake of the paleobiological revolution of the 1970s and 1980s, paleontologists continue to investigate far-reaching questions about how evolution works. Many of those questions have a philosophical dimension. How is macroevolution related to evolutionary changes within populations? Is evolutionary history contingent? How much can we know about the causes of evolutionary trends? How do paleontologists read the patterns in the fossil record to learn about the underlying evolutionary processes? Derek Turner explores these and other questions, introducing the reader (...) to exciting recent work in the philosophy of paleontology and to theoretical issues including punctuated equilibria and species selection. He also critically examines some of the major accomplishments and arguments of paleontologists of the last 40 years. (shrink)

A closely argued book about what the negative tradition in Western theology involves.

In earlier work, I predicted that we would probably not be able to determine the colors of the dinosaurs. I lost this epistemic bet against science in dramatic fashion when scientists discovered that it is possible to draw inferences about dinosaur coloration based on the microstructure of fossil feathers (Vinther et al., 2008). This paper is an exercise in philosophical error analysis. I examine this episode with two questions in mind. First, does this case lend any support to epistemic optimism (...) about historical science? Second, under what conditions is it rational to make predictions about what questions scientists will or will not be able answer? In reply to the first question, I argue that the recent work on the colors of the dinosaurs matters less to the debate about the epistemology of historical science than it might seem. In reply to the second question, I argue that it is difficult to specify a policy that would rule out the failed bet without also being too conservative. (shrink)

David Lewis defends the thesis of the asymmetry of overdetermination: later affairs are seldom overdetermined by earlier affairs, but earlier affairs are usually overdetermined by later affairs. Recently, Carol Cleland has argued that since the distinctive methodologies of historical science and experimental science exploit different aspects of this asymmetry, the methodology of historical science is just as good, epistemically speaking, as that of experimental science. This paper shows, first, that Cleland's epistemological conclusion does not follow from the thesis of the (...) asymmetry of overdetermination, because overdetermination is compatible with epistemic underdetermination. The paper also shows, contra Cleland, that there is at least one interesting sense in which historical science is epistemically inferior to experimental science, after all, because local underdetermination problems are more widespread in historical than in experimental science.

Argument-giving reasons for a view-is our model of rational dispute resolution. Fogelin suggests that certain "deep" disagreements cannot be resolved in this way because features of their context "undercut the conditions essential to arguing" . In this paper we add some detail to Fogelin's treatment of intractable disagreements. In doing so we distinguish between his relatively modest claim that some disputes cannot be resolved through argument and his more radical claim that such disputes are beyond rational resolution. This distinction, along (...) with some ofthe detail we add to Fogelin's treatment, sheds some useful light on the project of informal logic. (shrink)

The proposition that the existence of God is demonstrable by rational argument is doubted by nearly all philosophical opinion today and is thought by most Christian theologians to be incompatible with Christian faith. This book argues that, on the contrary, there are reasons of faith why in principle the existence of God should be thought rationally demonstrable and that it is worthwhile revisiting the theology of Thomas Aquinas to see why this is so. The book further suggests that philosophical objections (...) to proofs of God's existence rely upon an attenuated and impoverished conception of reason which theologians of all monotheistic traditions might wish to reject. Denys Turner proposes that on a broader and deeper conception of it, human rationality is open to the 'sacramental shape' of creation as such and in its exercise of rational proof of God it in some way participates in that sacramentality of all things.

This paper develops a critical response to John Beatty’s recent (2006) engagement with Stephen Jay Gould’s claim that evolutionary history is contingent. Beatty identifies two senses of contingency in Gould’s work: an unpredictability sense and a causal dependence sense. He denies that Gould associates contingency with stochastic phenomena, such as drift. In reply to Beatty, this paper develops two main claims. The first is an interpretive claim: Gould really thinks of contingency has having to do with stochastic effects at the (...) level of macroevolution, and in particular with unbiased species sorting. This notion of contingency as macro-level stochasticity incorporates both the causal dependence and the unpredictability senses of contingency. The second claim is more substantive: Recent attempts by other scientists to put Gould’s claim to the test fail to engage with the hypothesis that species sorting sometimes resembles a lottery. Gould’s claim that random sorting is a significant macroevolutionary phenomenon remains an intriguing and largely untested live hypothesis about evolution. (shrink)

Eric Katz’s insight about the relationship between causal history and value only generates a principled critique of de-extinction when conjoined with the diminishment claim, or the claim that human involvement in something’s causal history diminishes its value. The diminishment claim is a form of negative anthropocentrism. In addition to thinking about de-extinction as a form of ecological restoration, we could think of it as a form of environmental artwork. This reframing highlights the implausibility of the diminishment claim.

The precautionary principle states, roughly, that it is better to take precautionary measures now than to deal with serious harms to the environment or human health later on. This paper builds on the work of Neil A. Manson in order to show that the precautionary principle, in all of its forms, is fraught with vagueness and ambiguity. We examine the version of the precautionary principle that was formulated at the Wingspread Conference sponsored by the Science and Environmental Health Network in (...) 1998. That version fails to indicate who must bear the cost of precaution; what constitutes a threat of harm; how much precaution is too much; and what should be done when environmental concerns and concern for human health pull in different directions. Whether this vagueness is a strength or weakness of the principle depends on what purpose(s) the precautionary principle is supposed to serve. (shrink)

The practice of paleontology has an aesthetic as well as an epistemic dimension. Paleontology has distinctively aesthetic aims, such as cultivating sense of place and developing a better aesthetic appreciation of fossils. Scientific cognitivists in environmental aesthetics argue that scientific knowledge deepens and enhances our appreciation of nature. Drawing on that tradition, this Element argues that knowledge of something's history makes a difference to how we engage with it aesthetically. This means that investigation of the deep past can contribute to (...) aesthetic aims. Aesthetic engagement with fossils and landscapes is also crucial to explaining paleontology's epistemic successes. (shrink)

One of the first questions that paleontologists ask when they identify a large-scale trend in the fossil record (e.g., size increase, complexity increase) is whether it is passive or driven. In this article, I explore two questions about driven trends: (1) what is the underlying cause or source of the directional bias? and (2) has the strength of the directional bias changed over time? I identify two underdetermination problems that prevent scientists from giving complete answers to these two questions.

This paper offers a paleobiological perspective on the debate concerning the possible use of biotechnology to bring back extinct species. One lesson from paleobiology is that extinction selectivity matters in addition to extinction rates and extinction magnitude. Combining some of Darwin’s insights about artificial selection with the theory of species selection that paleobiologists developed in the 1970s and 1980s provides a useful context for thinking about de-extinction. Using recent work on the prioritization of candidate species for de-extinction as a test (...) case, the paper argues that de-extinction would be a form of artificial species selection in which humans influence which species persist vs. go extinct. This points to a serious gap in our ethical theory: Much work has been done to clarify the value of biological diversity, but we also need theoretical guidance for decisions that amount to species sorting, and that will shape the macroevolutionary future.

Abstract Starting with Ben-Menahem's definition of historical contingency as sensitivity to variations in initial conditions, we suggest that historical events and processes can be thought of as forming a complex landscape of contingency and necessity. We suggest three different ways of extending and elaborating Ben-Menahem's concepts: (1) By supplementing them with a notion of historical disturbance; (2) by pointing out that contingency and necessity are subject to scaling effects; (3) by showing how degrees of contingency/necessity can change over time. We (...) also argue that further development of Sterelny's notion of conditional inevitability leads to our conclusion that the topography of historical contingency is something that can change over time.

Lately there has been a wave of criticism of the concept of living fossils. First, recent research has challenged the status of paradigmatic living fossil taxa, such as coelacanths, cycads, and tuataras. Critics have also complained that the living fossil concept is vague and/or ambiguous, and that it is responsible for misconceptions about evolution. This paper defends a particular phylogenetic conception of living fossils, or taxa that exhibit deep prehistoric morphological stability; contain few extant species; and make a high contribution (...) to phylogenetic diversity. The paper shows how this conception of living fossils can make sense of recent research on contested cases. The phylogenetic living fossil concept has both theoretical and practical importance: theoretical, because it picks out an important explanatory target for evolutionary theory; and practical, because it picks out taxa that we might wish to prioritize for conservation. The best way to defend the concept of living fossils is to get clearer about the reasons for defending living fossil taxa. (shrink)

This paper examines a particularly egregious example of a NIMBY claim and considers three proposals for explaining what about that claim might be ethically problematic: The NIMBY claimant is being selfish or self-serving; The NIMBY claim cannot be morally justified, because respecting everyone's NIMBY claims leaves communities worse off; and if policymakers were to defer to people's NIMBY claims, they would end up perpetuating environmental injustices. We argue that these proposals fail to explain why there is anything wrong with the (...) NIMBY claim per se. (shrink)

In Rock, Bone, and Ruin, Adrian Currie offers an account of how historically oriented researchers in paleontology, archaeology, and the geosciences make the most out of their epistemically unlucky circumstances. He argues that there are three things, in particular, that can help scientists gain traction in unlucky circumstances: methodological omnivory, epistemic scaffolding, and “empirically grounded speculation”. Together, these three aspects of the practice of historical science help explain its successes. I largely agree with Currie’s account of methodological omnivory and epistemic (...) scaffolding, but I want to raise some critical questions about his discussion of speculation. (shrink)

Entrenched biases in favour of large, charismatic mammals, towards predators, towards terrestrial animals and towards species that have cultural importance can influence the selection of candidate species for de-extinction research. Often, the species with the highest existence value will also be the ones that raise the most serious animal welfare concerns.

Within the past ten years, the discussion of the nature of folk psychology and its role in explaining behavior and thought has become central to the philosophy of mind. However, no comprehensive account of the contemporary debate or collection of the works that make up this debate has yet been available. Intending to fill this gap, this volume begins with the crucial background for the contemporary debate and proceeds with a broad range of responses to and developments of these works (...) -- from those who argue that "folk theory" is a misnomer to those who regard folk theory as legitimately explanatory and necessary for any adequate account of human behavior. Intended for courses in the philosophy of mind, psychology, and science, as well as anthropology and social psychology, this anthology is also of great value in courses focusing on folk models, eliminative materialism, explanation, psychological theory, and -- in particular -- intentional psychology. It is accessible to both graduate students and upper-division undergraduate students of philosophy and psychology as well as researchers. As an aid to students, a thorough discussion of the field and the articles in the anthology is provided in the introduction; as an aid to researchers, a complete bibliography is also provided.

This paper develops responses to several critics who commented on an earlier paper that we published in this journal. In that paper, we argued that there is nothing necessarily wrong with NIMBY claims or those who make them. The critics raised some important issues, such as whether “NIMBY” is essentially a pejorative term; the possibility that NIMBY claimants are saying something deep about the noncomparability of places; what exactly it means for policy makers to defer to a NIMBY claim; the (...) relationship between NIMBY and environmental justice claims; and whether there is any principled way to distinguish good from bad NIMBY claims. We explore these issues further, and in the course of responding to the critics, we develop some further reasons for skepticism about the prospects for distinguishing good from bad NIMBY claims in a principled way.

Scientific realism is fundamentally a view about unobservable things, events, processes, and so on, but things can be unobservable either because they are tiny or because they are past. The familiar abductive arguments for scientific realism lend more justification to scientific realism about the tiny than to realism about the past. This paper examines both the “basic” abductive arguments for realism advanced by philosophers such as Ian Hacking and Michael Devitt, as well as Richard Boyd’s version of the inference to (...) the best explanation of the success of science, and shows that these arguments provide less support to historical than to experimental realism. This is because unobservably tiny things can function both as unifiers of the phenomena and as tools for the production of new phenomena, whereas things in the past can only serve as unifiers of the phenomena. The upshot is that realists must not suppose that by presenting arguments for experimental realism they have thereby defended realism in general.Author Keywords: Author Keywords: Realism; Abduction; Historical science; Hacking; Devitt; Boyd.

Negative theology or apophasis - the idea that God is best identified in terms of 'absence', 'otherness', 'difference' - has been influential in modern Christian thought, resonating as it does with secular notions of negation developed in continental philosophy. Apophasis also has a strong intellectual history dating back to the early Church Fathers. Silence and the Word both studies the history of apophasis and examines its relationship with contemporary secular philosophy. Leading Christian thinkers explore in their own way the extent (...) to which the concept of the apophatic illumines some of the deepest doctrinal structures of Christian faith, and of Christian self-understanding both in terms of its historical and contemporary situatedness, showing how a dimension of negativity has characterised not only traditional mysticism but most forms of Christian thought over the years.

The distinction between idiographic science, which aims to reconstruct sequences of particular events, and nomothetic science, which aims to discover laws and regularities, is crucial for understanding the paleobiological revolution of the 1970s and 1980s. Stephen Jay Gould at times seemed conflicted about whether to say (a) that idiographic science is fine as it is or (b) that paleontology would have more credibility if it were more nomothetic. Ironically, one of the lasting results of the paleobiological revolution was a new (...) way of doing historical science that defies categorization as idiographic or nomothetic. Yet the tension between (a) and (b) persists in some recent work in the philosophy of science, with Carol Cleland defending a version of (a) and Dan McShea and Robert Brandon defending a version of (b). In placing Cleland's work into conversation with that of McShea and Brandon, this paper defends a third (c) synthetic approach that emphasizes the blending of idiographic and nomothetic work.

Leaving so few traces of himself behind, Thomas Aquinas seems to defy the efforts of the biographer. Highly visible as a public teacher, preacher, and theologian, he nevertheless has remained nearly invisible as man and saint. What can be discovered about Thomas Aquinas as a whole? In this short, compelling portrait, Denys Turner clears away the haze of time and brings Thomas vividly to life for contemporary readers—those unfamiliar with the saint as well as those well acquainted with his teachings. (...) Building on the best biographical scholarship available today and reading the works of Thomas with piercing acuity, Turner seeks the point at which the man, the mind, and the soul of Thomas Aquinas intersect. Reflecting upon Thomas, a man of Christian Trinitarian faith yet one whose thought is grounded firmly in the body’s interaction with the material world, a thinker at once confident in the powers of human reason and a man of prayer, Turner provides a more detailed human portrait than ever before of one of the most influential philosophers and theologians in all of Western thought.

This paper offers an account of the relationship between inference and explanation in functional morphology which combines Robert Brandon's theory of adaptation explanation with standard accounts of inference to the best explanation. Inferences of function from structure, it is argued, are inferences to the best adaptation explanation. There are, however, three different approaches to the problem of determining which adaptation explanation is the best. The theory of inference to the best adaptation explanation is then applied to a case study from (...) the history of functional morphology: the case of the crested duckbilled dinosaurs. (shrink)

This article reviews the history of international mobility of students from China to other countries over the century and a half from 1870 to the present day. Different motivations, goals, courses, and knowledge are considered, together with how the purposes of individuals have matched national policy. Implications for the future development in a globalized context are briefly considered.

Horseshoe crabs (Limulus polyphemus) have been in decline in Long Island Sound, and recently there has been discussion of whether the state of Connecticut should stop issuing licenses for commercial harvesting. This paper argues that in spite of concerns about the living fossil concept, the fact that the horseshoe crabs are living fossils should count in favor of more stringent protection. The paper distinguishes four different views about the status of the living fossil concept: 1) eliminativism; 2) redefinition; 3) reframing; (...) and 4) conceptual pluralism. Approaches 2–4 all treat the criteria associated with living fossils as picking out distinctive features of evolutionary history. Those distinctive features of evolutionary history link up with conservation values in several ways. More generally, drawing upon relevant work in environmental philosophy, it is argued that evolutionary history is relevant to aesthetic and environmental value. Moreover, eliminativists have trouble rendering intelligible a striking pattern in the recent scientific literature. Researchers undertaking conservation-relevant work frequently highlight the living fossil status of the taxa under study. (shrink)

In the appropriate contexts reasoning is a powerful tool for producing intersubjective agreement about what counts as the best answer to a question that generates inquiry; sometimes employing arguments can lead to agreement about what is the right answer. In this paper we hope to show, however, that unabashed optimism about the power of argument is misplaced. Such optimism rests on an implausible picture of the power of articulation. Sentences cashed out as reasons to believe another sentence is true cannot (...) bridge large gaps in substantive understanding. A failure to realize this fact, moreover, leads to an uncautious and unreflective optimism about the power of argument that ultimately threatens the very reasons-giving process. What is needed, then, is a much more modest sense of the role of argument. (shrink)

In order to defend the regress argument for foundationalism against Post’s objection that relevant forms of inferential justification are not transitive, Lydia McGrew and Timothy McGrew define a relation E of positive evidence, which, they contend, has the following features: It is a necessary condition for any inferential justification; it is transitive and irreflexive; and it enables both a strengthened regress argument proof against Post’s objection and an argument that nothing can ever appear in its own justificational ancestry. In reply, (...) we construct in their own terms both a counterexample to the would-be transitivity of E, and a related objection to their never-in-its-own-ancestry argument. We also rebut their rejection of certain counterexamples to the would-be transitivity of some forms of inferential justification. By doing so, and by questioning their transitivity claim for E, we aim to further the project of undermining the circularity arguments advanced by a zoo of skeptics, relativists, antirealists and internalists against realism and externalism.

Understanding the mechanisms of early embryonic patterning and the timely allocation of specific cells to embryonic regions and fates as well as their development into tissues and organs, is a fundamental problem in Developmental Biology. The classical explanation for this process had been built around the notion of positional information. Accordingly the programmed appearance of sources of Morphogens at localized positions within a field of cells directs their differentiation. Recently, the development of organs and tissues from unpatterned and initially identical (...) stem cells (adult and embryonic) has challenged the need for positional information and even the integrity of the embryo, for pattern formation. Here we review the emerging area of organoid biology from the perspective of Developmental Biology. We argue that the events underlying the development of these systems are not purely linked to “self‐organization,” as often suggested, but rather to a process of genetically encoded self‐assembly where genetic programs encode and control the emergence of biological structures.

The empirical results from recent randomised controlled studies on remote, intercessory prayer remain mixed. Several studies have, however, appeared in prestigious medical journals, and it is believed by many researchers, including apparent sceptics, that it makes sense to study intercessory prayer as if it were just another experimental drug treatment. This assumption is challenged by discussing problems posed by the need to obtain the informed consent of patients participating in the studies; pointing out that if the intercessors are indeed conscientious (...) religious believers, they should subvert the studies by praying for patients randomised to the control groups; and showing that the studies in question are characterised by an internal philosophical tension because the intercessors and the scientists must take incompatible views of what is going on: the intercessors must take a causation-first view, whereas the scientists must take a correlation-first view. It therefore makes no ethical or methodological sense to study remote, intercessory prayer as if it were just another drug. (shrink)

In Ruling Passions, Simon Blackburn contends that we should reject sensibility theory because it serves to support a conservative complacency. Blackburn's strategy is attractive in that it seeks to win this metaethical dispute – which ultimately stems from a deep disagreement over antireductionism – on the basis of an uncontroversial normative consideration. Therefore, Blackburn seems to offer an easy solution to an apparently intractable debate. We will show, however, that Blackburn's argument against sensibility theory does not succeed; it is no (...) more supportive of conservative complacency than Blackburn's noncognitivism. A victory for noncognitivism cannot be so easily won. (shrink)

This article explores the process of university Ethical Review both as lived experience and as part of institutional governance at an English university. The article uses Blackburn's distinction between ethics and Ethics (Ethics?A Very Short Introduction, Oxford University Press, Oxford, 2001) as a framework to examine the themes of ?vulnerability?, ?power? and ?relationships?. These themes are analysed closely both within the institutional and the fieldwork contexts, attempting to include the perspectives of all those involved in the research ethics process. The (...) article does not seek to draw any definitive conclusions but rather to stimulate, and add to the iterative discussion on the process of Ethical Review within institutions. Nonetheless, it does conclude by making some suggestions concerning the way in which the lived experience of ethics could better inform the practice of institutional Ethical Review. (shrink)
