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)

Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...) OBO principles were not originally encoded in a precise fashion, and interpretation was subjective. Here we show how we have addressed this by formally encoding the OBO principles as operational rules and implementing a suite of automated validation checks and a dashboard for objectively evaluating each ontology’s compliance with each principle. This entailed a substantial effort to curate metadata across all ontologies and to coordinate with individual stakeholders. We have applied these checks across the full OBO suite of ontologies, revealing areas where individual ontologies require changes to conform to our principles. Our work demonstrates how a sizable federated community can be organized and evaluated on objective criteria that help improve overall quality and interoperability, which is vital for the sustenance of the OBO project and towards the overall goals of making data FAIR.

This essay describes computational semantic networks for a philosophical audience and surveys several approaches to semantic-network semantics. In particular, propositional semantic networks are discussed; it is argued that only a fully intensional, Meinongian semantics is appropriate for them; and several Meinongian systems are presented.

The Doctrine of Double Effect (DDE) is an influential non-consequentialist principle positing a role for intention in affecting the moral permissibility of some actions. In particular, the DDE focuses on the intend/foresee distinction, the core claim being that it is sometimes permissible to bring about as a foreseen but unintended side-effect of one’s action some harm it would have been impermissible to aim at as a means or as an end, all else being equal. This article explores the meaning and (...) application of the DDE along with current debates over the nature of the intend/foresee distinction and its moral significance. How is the line between intended effects and merely foreseen but unintended side-effects to be drawn, and how are problem cases best handled? What is an appropriate methodology for debating the tenability of the DDE? How might the DDE interact with other non-consequentialist principles, and how might it be modified to capture other related factors (resulting perhaps in a Doctrine of Triple Effect) or to avoid certain problem cases? Does the DDE make permissibility turn on the actual intentions of particular agents, as critics such as Thomson and Scanlon assume, or is the role of intention more abstract? (shrink)

It seems impossible to foresee man's future. However, we do see clearly that the past determines our present in many realms : language, concept of the world, religion, science, law. Moreover, certain biological and physiological conditions appear to be so characteristic of the human species that we would not really be concerned with humanity if men managed to free themselves of these conditions.

There are many branches of philosophy called “the philosophy of X,” where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments.

This essay examines the role of non-existent objects in "epistemological ontology" — the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Außersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

Ethical realists hold that our ethical concepts, thoughts, and claims are in the business of representing ethical reality, by representing evaluative or normative properties and facts as aspects of reality, and that such representations are at least sometimes accurate. Non-naturalist realists add the further claim that ethical properties and facts are ultimately non-natural, though they are nonetheless worldly. My aim is threefold: to elucidate the sort of representation involved in ethical evaluation on realist views; to clarify what exactly is represented (...) and how non-naturalism comes into the picture for non-naturalists; and to defend worldly non-naturalism against some objections. The first question addressed is how we should model evaluation on any realist view, which should in turn guide the identification of which properties and facts are credibly regarded as ‘evaluative’ ones. Then the question is: what role might non-natural properties and facts play, and how are they related to what is represented in ethical evaluation? Once that is clear, we will be in a position to answer certain objections to non-naturalist realism from Jackson, Gibbard, Bedke, and Dreier. I argue that the objections all mischaracterize the role played by non-natural properties and facts on plausible versions of non-naturalist realism. (shrink)

Critical Review of Searle's Minds, Brains and Science.

A critical survey of some attempts to define ‘computer’, beginning with some informal ones, then critically evaluating those of three philosophers, and concluding with an examination of whether the brain and the universe are computers.

I begin by distinguishing two general approaches to metaethics and ontology. One in effect puts our experience as engaged ethical agents on hold while independent metaphysical and epistemological inquiries, operating by their own lights, deliver metaethical verdicts on acceptable interpretations of our ethical lives; the other instead keeps engaged ethical experience in focus and allows our reflective interpretation of it to shape our metaphysical and epistemological views, including our ontology. While the former approach often leads to deflationary views, the latter (...) may lead us to enrich our metaethical picture as needed to capture robust objectivity and categorical normative authority for ethics. Assuming, as I have argued elsewhere, that this requires positing irreducibly evaluative or normative properties and facts, the question I take up here is what ontological implications this has. I argue against quietist non-naturalist views, which maintain that positing such properties and facts either has no ontological implications or has only domain-specific ontological implications that likewise imply nothing about what the world contains. Against these views, I advocate a worldly, dual-aspect view, locating irreducibly evaluative or normative properties as features of relevant worldly things. But while I have previously defended this view as a form of non-naturalism, I here explore the possibility of instead seeing it as a new, more expansive form of naturalism—what might be called “Non-Scientistic Naturalism”—inspired by parallel attempts in the philosophy of mind to accommodate irreducibly phenomenal properties within a more expansive physicalism.

The famous ‘trolley problem’ began as a simple variation on an example given in passing by Philippa Foot , involving a runaway trolley that cannot be stopped but can be steered to a path of lesser harm. By switching from the perspective of the driver to that of a bystander, Judith Jarvis Thomson showed how the case raises difficulties for the normative theory Foot meant to be defending, and Thomson compounded the challenge with further variations that created still more puzzles (...) of broader interest. In recent years, her thought experiments have even been co-opted by psychologists engaged in the empirical study of moral judgment . Yet more than thirty years after launching the trolley problem, Thomson has now strikingly reversed course, retracting the very claim she had originally used to raise puzzles for Foot. I shall argue that this reversal is a mistake, leading to a needlessly counterintuitive, contrarian position about damage-control cases. Instead of overturning her earlier position, her new variations merely uncover a surprising insight about the conditions under which one may permissibly sacrifice another for a good end.1. The central case at issue is what Thomson now calls Bystander's Two Options: you are a bystander who sees a runaway trolley headed toward five innocent people who cannot move off the track; you cannot stop the trolley, but you have access to a switch that will divert it onto a side track where one innocent person is trapped. Is it permissible to throw the switch and divert the trolley toward lesser harm? The common answer, and Thomson's earlier one, is that it is: in cases like this, where there is a public threat and we can act on it so …. (shrink)

The differentiation of mammalian neurons during development is a highly complex process involving regulation and coordination of gene expression at multiple steps. The P19 mouse embryonal carcinoma cell line is a suitable model system with which to analyze regulation of neuronal differentiation. These multipotential cells can be maintained and propagated in tissue culture in an undifferentiated state. Exposure of aggregated P19 cells to retinoic acid results in the differentiation of cells with many fundamental phenotypes of mammalian neurons. Undifferentiated P19 cells (...) are amenable to genetic manipulations such as transfection and establishment of stable clonal cell lines expressing introduced genes. Proteins that play a key role in the neuronal differentiation of P19 cells are beginning to be identified. These include retinoic acid receptors, the epidermal growth factor receptor and the transcription factors Oct‐3 and Brn‐2. The biological and technical advantages of this system should facilitate deeper analysis of the activities of proteins that play a role in neuronal differentiation. (shrink)

Ford’s Helen Keller Was Never in a Chinese Room claims that my argument in How Helen Keller Used Syntactic Semantics to Escape from a Chinese Room fails because Searle and I use the terms ‘syntax’ and ‘semantics’ differently, hence are at cross purposes. Ford has misunderstood me; this reply clarifies my theory.

The author identifies the structure of Sharon Street's skeptical challenge to non-naturalist, normative epistemic realism as an argument that NNER is liable to reliability defeat and then argues that Street's argument fails, because it itself is subject to reliability defeat. As the author reconstructs Street's argument, it is an argument that the normative epistemic judgments of the realist could only be probabilistically sensitive to normative epistemic truths by sheer chance. The author then recaps Street's own naturalist translation of normative epistemic (...) judgments into purely descriptive, contingent probability statements, and argues that, on her own terms, the reasoning that leads her to rationally believe in evolutionary theory could only be probabilistically sensitive to the relevant purely descriptive, contingent probabilities by sheer chance. The author's argument is addressed to Street, but it applies to all evolutionary naturalist accounts of epistemic rationality. The author explains how his argument differs from Plantinga's Evolutionary Argument Against Naturalism and shows how it avoids the objections to Plantinga's EAAN. The author closes with the outline of an explanation of how evolution could have made human reasoning probabilistically sensitive to metaphysically necessary normative epistemic standards, even though those standards did not exert and, indeed, could not have exerted any kind of causal influence on the evolutionary process.

Increasingly, medical students are required to face up to ethical issues in their training and practice. At the same time, there is growing interest in philosophy courses in the ethical issues raised by medical practice. This textbook, designed primarily for students of medicine, develops the issues to a philosophical level complex enough to be satisfying to students of philosophy as well as MA students on applied ethics courses. The author advocates an approach to medical ethics which breaks out of the (...) straitjacket of the narrow choice between utilitarian or deontological theory, and contains a valuable discussion of practical wisdom. It maintains a balance between case studies and philosophical arguments - which are developed in a historical context, and will be of interest at all levels of the medical profession. (shrink)

The philosophy of religion as a distinct discipline is an innovation of the last two hundred years, but its central topics--the existence and nature of the divine, humankind's relation to it, the nature of religion and its place in human life--have been with us since the inception of philosophy. Philosophers have long critically examined the truth of (and rational justification for) religious claims, and have explored such philosophically interesting phenomena as faith, religious experience and the distinctive features of religious discourse. (...) The second half of the twentieth-century has been an especially fruitful period, with philosophers using new developments in logic and epistemology to mount both sophisticated defenses of, and attacks on, religious claims. The Oxford Handbook of Philosophy of Religion contains newly commissioned chapters by 21 prominent experts who cover the field in a comprehensive but accessible manner. Each chapter is expository, critical, and representative of a distinctive viewpoint. The Handbook is divided into two sections. The first, "Problems," covers the most frequently discussed topics, among them arguments for God's existence, the problem of evil, and religious epistemology. The second is called "Approaches" and contains four essays assessing the advantages and disadvantages of different methods of practicing philosophy of religion. The Handbook offers contributors of high stature who present substantive and in-depth treatment of the most central topics. It is a must-have reference for anyone with an interest in philosophy and religion. (shrink)

Alexius Meinong developed a notion of defective objects in order to account for various logical and psychological paradoxes. The notion is of historical interest, since it presages recent work on the logical paradoxes by Herzberger and Kripke. But it fails to do the job it was designed for. However, a technique implicit in Meinong's investigation is more successful and can be adapted to resolve a similar paradox discovered by Romane Clark in a revised version of Meinong's Theory of Objects due (...) to Rapaport. One family of paradoxes remains, but it is argued that they are unavoidable and relatively harmless. (shrink)

Andreas Mogensen has recently argued that the current debate over evolutionary debunking in ethics is mired in confusion due to a simple fallacy committed by debunkers and uncritically taken on board by their opponents. I argue that no party to this debate is involved in the type of confusion and fallacy Mogensen has in mind, which he himself notes would be an absurd and outlandish mistake for anyone to make in other domains. Debunkers do plausibly commit an error in their (...) explanatory claims about our moral beliefs, and it is related to an issue Mogensen discusses, but it is not the confusion and fallacy he identifies.

Despite widespread agreement that we have moral responsibilities to future generations, many are reluctant to frame the issues in terms of justice and rights.There are indeed philosophical challenges here, particularly concerning nonoverlapping generations. They can, however, be met. For example, talk of justiceand rights for future generations in connection with climate change is both appropriate and important, although it requires revising some common theoreticalassumptions about the nature of justice and rights. We can, in fact, be bound by the rights of (...) future people, despite the “non-identity problem,” and the force of these rights cannot be diluted by “discounting” future costs. Moreover, a rights-based approach provides an effective answer to political arguments against taking mandatory measures to curb greenhouse gas emissions when these are unpopular with a democratic populace.

In this paper I argue against the view of G.E.L. Owen that the second version of the Third Man Argument is a sound objection to Plato's conception of Forms as paradigms and that Plato knew it. The argument can be formulated so as to be valid, but Plato need not be committed to one of its premises. Forms are self-predicative, but the ground of self-predication is not the same as that of ordinary predication.

This paper seeks to explore the significance of a specific kind of religious experience for the rationality of religious belief. The context for this is a gap between what is often allowed as rational and what is embraced as certain in the life of faith. The claim to certainty at issue is related to the work and experience of the Holy Spirit; this experience has a structure which is explored phenomenologically. Thereafter various ways of cashing in the epistemic value of (...) the purported claim to certainty are examined. (shrink)

Although philosophical theologians have sometimes claimed that human beings are necessarily dependent on God, few have developed the idea with any precision. Jonathan Edwards is a notable exception, providing a detailed and often novel account of humanity’s essential ontological, moral, and soteriological dependence on God.

In the movieRegarding Henry, the main character, Henry Turner, is a lawyer who suffers brain damage as a result of being shot during a robbery. Before being wounded, the Old Henry Turner had been a successful lawyer, admired as a fierce competitor and well-known for his killer instinct. As a result of the injury to his brain, the New Henry Turner loses the personality traits that had made the Old Henry such a formidable adversary.

Part I argues that ontological arguments, like other classical proofs of the existence of God, are parts of larger arguments in which they are embedded. These larger arguments include reasons supporting the proofs’ premises and responses to them, and to the proofs’ claims to validity and non-circularity, since, in the final analysis, our assessment of the proofs will express our best judgment of the cumulative force of all the considerations bearing on their overall adequacy. Part II illustrates these points by (...) examining contemporary defences of, and attacks on, one of the ontological argument’s central premises, namely, that God’s existence is logically possible.

Is 50 considered “old”? When do we stop being considered “young”? If individuals could choose to be any age, what would it be? In a sample of 502,548 internet respondents ranging in age from 10 to 89, we examined age differences in aging perceptions (e.g., how old do you feel?) and estimates of the timing of developmental transitions (e.g., when does someone become an older adult?). We found that older adults reported older perceptions of aging (e.g., choosing to be older, (...) feeling older, being perceived as older), but that these perceptions were increasingly younger than their current age. The age to which individuals hope to live dramatically increased after age 40. We also found that older adults placed the age at which developmental transitions occurred later in the life course. This latter effect was stronger for transitions involving middle-age and older adulthood compared to transitions involving young adulthood. The current study constitutes the largest study to date of age differences in age perceptions and developmental timing estimates and yielded novel insights into how the aging process may affect judgments about the self and others.

Rolston (1988) argues that in order to act ethically in the environment, moral agents must assume that their actions are potentially harmful, and then strive to prove otherwise before implementing that action. In order to determine whether or not an action in the environment is harmful requires the tools of applied epistemology in order to act in accord with Rolston’s ethical prescription. This link between ethics and epistemology demands a closer look at the relationship between confirmation theory, particularly notions of (...) plausibility, in the philosophy of science and environmental ethics. Upon taking this look, I conclude that, at least logically, we are no better off assuming that actions are maximally risky (Rolston) than when we assume minimal risk. “Our vulnerability to error is greatest not from the things that we include in the model, but from the prophecies we leave out entirely.” Francis Bretherton “What is the main epistemic problem concerning science? I take it that it is the explication of how we compare and evaluate theories, as a basis either for theory acceptance or for practical action.” Bas van Fraassen “We face two kinds of ethical difficulties. One is where we know what ought to be done but not how to get the company to do it. The other is where we do not know what is right. We do not know the facts, or how to weigh the facts, especially statistical ones. We do not know the probabilities for development of future technologies. We do not know how to attach values to facts, or how to trade this good off against that one.” Holmes Rolston. (shrink)

The late Hector-Neri Castañeda, the Mahlon Powell Professor of Philosophy at Indiana University, and founding editor of Noûs, has deeply influenced current analytic philosophy with diverse contributions, including guise theory, the theory of indicators and quasi-indicators, and the proposition/practition theory. This volume collects 15 papers--for the most part previously unpublished--in ontology, philosophy of language, cognitive science, and related areas by ex-students of Professor Castañeda, most of whom are now well-known researchers or even distinguished scholars. The authors share the conviction that (...) Castañeda's work must continue to be explored and that his philosophical methodology must continue to be applied in an effort to further illuminate all the issues that he so deeply investigated. The topics covered by the contributions include intensional contexts, possible worlds, quasi-indicators, guise theory, property theory, Russell's substitutional theory of propositions, event theory, the adverbial theory of mental attitudes, existentialist ontology, and Plato's, Leibniz's, Kant's, and Peirce's ontologies. An introduction by the editors relates all these themes to Castañeda's philosophical interests and methodology. (shrink)

Eric Wielenberg and I agree that basic moral truths are necessarily true. But Wielenberg thinks that, because these truths are necessary, they require no explanation, and I do not: some basic moral truths are not self-explanatory. I argue that Wielenberg’s reasons for thinking that my justification of that claim is inadequate are ultimately unconvincing.

Information processing theories of memory and skills can be reformulated in terms of how categories are physically and temporally related, a process called conceptual coordination. Dreaming can then be understood as a story-understanding process in which two mechanisms found in everyday comprehension are missing: conceiving sequences (chunking categories in time as a higher-order categorization) and coordinating across modalities (e.g., relating the sound of a word and the image of its meaning). On this basis, we can readily identify isomorphisms between dream (...) phenomenology and neurophysiology, and explain the function of dreaming as facilitating future coordination of sequential, cross-modal categorization (i.e., REM sleep lowers activation thresholds, “unlearning”).
