The use of neural transplantation to alleviate cognitive deficits is still in its infancy. We have an inadequate understanding of the deficits induced by different types of brain damage and their homologies in animal models against which to assess graft-induced recovery, and of the ways in which graft growth and function are influenced by factors within the host brain and the environment in which the host is operating. Further, use of fetal tissue may only be a transitory phase in the (...) search for appropriate donor sources. Nevertheless, findings from our laboratory and elsewhere have made a prima facie case for successful cognitive reconstruction by graft methods. (shrink)

Cognitive deficits were produced in rats by different methods of damaging the brain: chronic ingestion of alcohol, causing widespread damage to diffuse cholinergic and aminergic projection systems; lesions (by local injection of the excitotoxins, ibotenate, quisqualate, and AMPA) of the nuclei of origin of the forebrain cholinergic projection system (FCPS), which innervates the neocortex and hippocampal formation; transient cerebral ischaemia, producing focal damage especially in the CA1 pyramidal cells of the dorsal hippocampus; and lesions (by local injection of the neurotoxin, (...) colchicine) of the granule cells of the dentate gyrus. Following chronic alcohol or lesions of the FCPS, transplants of cholinergically rich fetal brain tissue into the terminal areas (neocortex and/or hippocampus) restored performance almost to control levels, with a time course consistent with growth of the transplants and integration with host tissue; transplants of cholinergically poor fetal tissue (hippocampus) were without effect, as were transplants of cholinergically rich tissue into the region containing the nuclei of origin of the FCPS. Grafts of primary cells enriched in glia and cultured neuroblastoma cells into the terminal areas of the FCPS were equally effective, suggesting that there are multiple mechanisms by which neural transplants can restore cognitive function following diffuse cholinergic damage. In contrast, after ischaemia- or neurotoxin-induced damage to CA1 or dentate granule cells respectively, cholinergically rich fetal transplants into the damaged hippocampal formation were ineffective in restoring performance. After ischaemic damage, however, performance was restored by suspension grafts of CA1 cells but not by transplants containing CA3 pyramidal cells or granule cells; and after colchicine damage it was restored by solid grafts containing granule but not CA1 pyramidal cells. Furthermore, electrophysiological evidence has demonstrated functional, graft type-specific host-graft functional neuronal connectivity. Thus, restoration of cognitive function by neural transplants is possible after damage to either diffuse (cholinergic) or point-to-point (intrahippocampal) forebrain systems, but the transplant must be appropriate to the damage to be repaired. Because the different types of brain damage studied provide analogues of human alcoholic dementia, Alzheimer's disease, and heart attack, these results are encouraging with regard to the eventual application of neural transplant surgery to the treatment of cognitive deficits in humans.

John Gibbons presents an original account of epistemic normativity. Belief seems to come with a built-in set of standards or norms. One task is to say where these standards come from. But the more basic task is to say what those standards are. In some sense, beliefs are supposed to be true. Perhaps they’re supposed to constitute knowledge. And in some sense, they really ought to be reasonable. Which, if any of these is the fundamental norm of belief? The (...) book argues against the teleological or instrumentalist conception of rationality that sees being reasonable as a means to our more objective aims, either knowledge or truth. And it tries to explain both the norms of knowledge and of truth in terms of the fundamental norm, the one that tells you to be reasonable. The importance of being reasonable is not explained in terms of what it will get you, or what you think it will get you, or what it would get you if only things were different. The requirement to be reasonable comes from the very idea of what a genuine requirement is. That’s where the built-in standards governing belief come from, and that’s what they are. (shrink)

John R. Schneider explores the problem that animal suffering, caused by the inherent nature of Darwinian evolution, poses to belief in theism. Examining the aesthetic aspects of this moral problem, Schneider focuses on the three prevailing approaches to it: that the Fall caused animal suffering in nature (Lapsarian Theodicy), that Darwinian evolution was the only way for God to create an acceptably good and valuable world (Only-Way Theodicy), and that evolution is the source of major, God-justifying beauty (Aesthetic Theodicy). (...) He also uses canonical texts and doctrines from Judaism and Christianity - notably the book of Job, and the doctrines of the incarnation, atonement, and resurrection - to build on insights taken from the non-lapsarian alternative approaches. Schneider thus constructs an original, God-justifying account of God and the evolutionary suffering of animals. His book enables readers to see that the Darwinian configuration of animal suffering unveiled by scientists is not as implausible on Christian theism as commonly supposed. (shrink)

Major shifts in the field of model theory in the twentieth century have seen the development of new tools, methods, and motivations for mathematicians and philosophers. In this book, John T. Baldwin places the revolution in its historical context from the ancient Greeks to the last century, argues for local rather than global foundations for mathematics, and provides philosophical viewpoints on the importance of modern model theory for both understanding and undertaking mathematical practice. The volume also addresses the impact (...) of model theory on contemporary algebraic geometry, number theory, combinatorics, and differential equations. This comprehensive and detailed book will interest logicians and mathematicians as well as those working on the history and philosophy of mathematics. (shrink)

Studies in Empirical Philosophy was published in 1962 shortly after Anderson's death and had been prepared by him to include most of his published articles from the Australasian Journal of Philosophy and Psychology. It also includes a couple of articles written especially for the book. It remains the main published source of material on Anderson's systematic philosophy. John Passmore has kindly granted permission for his introduction to be included in this new release. John Anderson (1893-1962) was Challis Professor (...) of Philosophy at the University of Sydney from 1927 until 1958. He is generally regarded as the most important philosopher to have worked in Australia. His students included not only academic philosophers but also important figures in politics, law and journalism. His impact upon Sydney's social and cultural life was enormous. (shrink)

When and why are coercion, indoctrination, manipulation, deception, and bullshit morally wrongful modes of influence in the context of educating children? Answering this question requires identifying what valid claims different parties have against one another regarding how children are influenced. Most prominently among these, it requires discerning what claims children have regarding whether and how they and their peers are influenced, and against whom they have these claims. The claims they have are grounded in the weighty interests they each equally (...) have in their wellbeing, prospective autonomy and being regarded with equal concern and respect. Plausibly children have valid claims regarding the content and means of influence they themselves are subjected to. For instance, considerations of concern and respect for children confer duties on others enable them to know important information and develop important skills. Children also plausibly have valid claims to be free from certain means of influence including indoctrination. This is because indoctrinatory practices threaten to diminish both their capacity to reason soundly, thereby constituting a wrongful harm, and their opportunities to form judgements and choices in response to relevant evidence and reasons, thereby constituting a wrong of disrespect.

I review recent empirical findings on knowledge attributions in lottery cases and report a new experiment that advances our understanding of the topic. The main novel finding is that people deny knowledge in lottery cases because of an underlying qualitative difference in how they process probabilistic information. “Outside” information is generic and pertains to a base rate within a population. “Inside” information is specific and pertains to a particular item’s propensity. When an agent receives information that 99% of all lottery (...) tickets lose (outside information), people judge that she does not know that her ticket will lose. By contrast, when an agent receives information that her specific ticket is 99% likely to lose (inside information), people judge that she knows that her ticket will lose. Despite this difference in knowledge judgments, people rate the likelihood of her ticket losing the exact same in both cases (i.e. 99%). The results shed light on other factors affecting knowledge judgments in lottery cases, including formulaic expression and participants’ own estimation of whether it is true that the ticket will lose. The results also undermine previous hypotheses offered for knowledge denial in lottery cases, including the hypotheses that people deny knowledge because they either deny justification or acknowledge a chance for error.

John Passmore was a renowned Australian empirical philosopher and historian of ideas. In this book, which was originally published in 1952, Passmore's intention was to disentangle certain main themes in Hume's philosophy and to show how they relate to Hume's main philosophic purpose. Rather than offering a detailed commentary, the text provides an account based on specificity and critical scholarship, seeking to complement the other more comprehensive works on Hume's philosophy that had become available around the same time. This (...) book will be of value to anyone with an interest in perspectives on Hume and Passmore's philosophical approach. (shrink)

In a fair, infinite lottery, it is possible to conclude that drawing a number divisible by four is strictly less likely than drawing an even number; and, with apparently equal cogency, that drawing a number divisible by four is equally as likely as drawing an even number.

Objectivity is a key concept both in how we talk about science in everyday life and in the philosophy of science. This Element explores various ways in which recent philosophers of science have thought about the nature, value and achievability of objectivity. The first section explains the general trend in recent philosophy of science away from a notion of objectivity as a 'view from nowhere' to a focus on the relationship between objectivity and trust. Section 2 discusses the relationship between (...) objectivity and recent arguments attacking the viability or desirability of 'value free' science. Section 3 outlines Longino's influential 'social' account of objectivity, suggesting some worries about drawing too strong a link between epistemic and ethical virtues. Section 4 turns to the value of objectivity, exploring concerns that notions of objectivity are politically problematic, and cautiously advocating in response a view of objectivity in terms of invariance.

_A new theory of how and why we cooperate, drawing from economics, political theory, and philosophy to challenge the conventional wisdom of game theory_ Game theory explains competitive behavior by working from the premise that people are self-interested. People don’t just compete, however; they also cooperate. John Roemer argues that attempts by orthodox game theorists to account for cooperation leave much to be desired. Unlike competing players, cooperating players take those actions that they would like others to take—which Roemer (...) calls “Kantian optimization.” Through rigorous reasoning and modeling, Roemer demonstrates a simpler theory of cooperative behavior than the standard model provides.

John Foster presents a penetrating investigation into the question: what is it to perceive a physical object? Is perceptual contact with a physical object, he asks, something fundamental, or does it break down into further factors? If the latter, what are these factors, and how do they combine to secure the contact? For most of the book, Foster addressed these questions in the framework of a realist view of the physical world. But the arguments which thereby unfold - arguments (...) which undermine direct realism and establish a version of the sense-datum theory - lead to the conclusion that we do no perceive physical objects at all. The only way to avoid this conclusion is by abandoning physical realism for a form of idealism, and this is the option which Foster finally embraces. The Nature of Perception makes an important contrbution to the ongoing debate: it sheds fresh light on the traditional issues, and breathes new life into positions which most current philosophers assumeto be dead.

Ever since humankind raised its head toward the heavens in search of universal understanding and spiritual fulfilment, wars, pogroms, persecution, prejudice, and contempt have been the means of resolving the many and varied disagreements that have arisen over matters religious. In his Letter Concerning Toleration, Locke offers a compelling plea for freedom of conscience and religious expression. He outlines the limits of social and political incursion into the realm of personal belief or non-belief, discusses the dangers of mixing church and (...) state, and strikes hard at those who would use the power of the state to fulfil religious or political goals. Rational persuasion is always to be encouraged in the hope that wayward souls may find a moral direction in life, but the use of force in such matters is unwarranted and unacceptable. Locke also addresses the question of denominational infighting and relations among the major religions. Talk of heresy and schism should be set aside in favour of understanding and co-operation to achieve mutually desirable social ends. (shrink)

In this awaited follow up to his book _Faithful Reason_, the well-known philosopher and Catholic thinker John Haldane brings his unrivalled insight to bear on questions of the existence of God and the nature and destiny of the human soul. His arguments weave elements drawn from philosophy of mind, epistemology and aesthetics, together with recurrent features of human experience to create a structure that simultaneously frames and supports ideas such as that the cosmos is a creation, human beings transcend (...) their material composition, and that human fulfilment lies beyond death. As in many of his other writings this volume blends themes from Aquinas with insights drawn from analytical philosophy and further establishes John Haldane as the leading 'analytical thomist'.

The somewhat superannuated “problem of other minds” has unexpectedly risen from the dead, and, in its current incarnation, concerns the mental states of those who never lived.

According to reliabilist virtue epistemology, or virtue reliabilism, knowledge is true belief that is produced by intellectual excellence (or virtue), where intellectual excellence is understood in terms of reliable, truth-directed cognitive dispositions. This essay explains why virtue reliabilism is a form of epistemological externalism, is a moderately naturalized epistemology, and is distinct from virtue responsibilism. We explain virtue reliabilism’s answers to various forms of skepticism, its solution to the Gettier Problem, and its explanation of the value of knowledge. We also (...) describe several varieties of contemporary virtue reliabilism. Finally, we offer replies to two recently prominent objections to virtue reliabilism: that it is committed to an untenable epistemological individualism, and that there are empirical reasons to doubt whether people generally have the kinds of intellectual abilities that virtue reliabilism requires for knowledge.

I review recent work from armchair and cross-cultural epistemology on whether humans possess a knowledge concept as part of a universal “folk epistemology.” The work from armchair epistemology fails because it mischaracterizes ordinary knowledge judgments. The work from cross-cultural epistemology provides some defeasible evidence for a universal folk epistemology. I argue that recent findings from comparative psychology establish that humans possess a species-typical knowledge concept. More specifically, recent work shows that knowledge attributions are a central part of primate social cognition, (...) used to predict others’ behavior and guide decision-making. The core primate knowledge concept is that of truth detection (across different sensory modalities) and retention (through memory) and may also include rudimentary forms of indirect truth discovery through inference. In virtue of their evolutionary heritage, humans inherited the primate social-cognitive system and thus share this core knowledge concept. (shrink)

'John Toland's Letters to Serena' is one of the most important texts of the early Enlightenment.

Stuhr develops his pragmatism by putting pluralism forward, setting aside absolutism and nihilism, opening new perspectives on democracy, and focusing on love.

Full color illustrations enhance this lyrical commitment to a new version (...) of pragmatism. (shrink)

John Barton is convinced that in many areas of ethical enquiry the Old Testament has much to teach us, and he argues his case in this new book, which developed out of lectures given both in Canada and in Oxford.

By (...) the end of the book it is clear that although the Old Testament comes to us from a remote, alien and apparently unsophisticated context, the powerful minds who worked on its books still have things to say which remain evocative and suggestive for our own moral enquiries.

An understanding of the nature of theology comprises an account of its object, its cognitive principles, its ends and its practitioners. The object of theology is two-fold: principally God the Holy Trinity, and derivatively all things in relation to God. God is considered first absolutely, then relatively; all other things are treated relative to God, under the aspect of creatureliness. The objective cognitive principle of theology is God’s infinite knowledge, of which God communicates a fitting share to creatures; the subjective (...) cognitive principle of theology is the regenerate human intellect. The ends of theology are scientific, contemplative and practical. The practitioners of theology are regenerate persons in the church whose creaturely intellect is instructed by God and all of whose works are accompanied by the practices of religion. (shrink)

The question of whether any of us can truly be held responsible for what we do is an issue that occupied the ancient Greeks and continues to entertain our leading thinkers. Whether we can be held responsible for our health, or lack thereof, has additional layers of complexity because of the way in which what we do over time impacts our health. Those of us who have ever self-deceptively wondered about the apparent shrinking of our belt or at the fact (...) that the stairs seem to have multiplied are familiar with the idea that our health can change gradually over time as a result of successive choices that we have made. While there are one-off behaviours that can have an impact on health, for example, a single exposure to a very high level of radiation, in general, ill health develops over time, within an environment and complex set of interactions with other people. The implications of that complexity are central to this issue’s Feature Article by Brown and Savulescu.1 They note that there is debate over whether responsibility should play a role in the allocation of healthcare, and, rather than taking a view on that issue, make a number of suggestions about how the concept of responsibility used in healthcare can be enriched by attending to the complex relationship between behaviour and health. ….

John Rist surveys the history of ethics from Plato to the present and offers a vigorous defence of an ethical theory based on a revised version of Platonic realism. In a wide-ranging discussion he examines well-known alternatives to Platonism, in particular Epicurus, Hobbes, Hume and Kant as well as contemporary 'practical reasoners', and argues that most post-Enlightenment theories of morality depend on an abandoned Christian metaphysic and are unintelligible without such grounding. He also argues that contemporary choice-based theories, whether (...) they take a strictly ethical or more obviously political form, are ultimately arbitrary in nature. His lively and accessible 2001 study is informed by a powerful sense of philosophical history, and will be of interest to both students and scholars of ethics. (shrink)

The Things in Heaven and Earth develops and applies the American philosophical naturalist tradition of the mid-20th century, specifically the work of three of the most prominent figures of what is called Columbia Naturalism: John Dewey, John Herman Randall Jr., and Justus Buchler. The book argues for the philosophical value and usefulness of this underappreciated tradition for a number of contemporary theoretical and practical issues, such as the modernist/postmodernist divide and debates over philosophical constructivism. Pragmatic naturalism offers a (...) distinctive ontology of constitutive relations. Relying on Buchler's ordinal ontology and on the relationality implicit in Dewey's instrumentalism, the book gives a detailed account of this approach in chapters that deal with issues in systematic ontology, epistemology, constructivism and objectivity, philosophical theology, art, democratic theory, foreign policy, education, humanism, and cosmopolitanism.

The ‘hard’ problem of consciousness is the seemingly intractable one of explaining the properties of consciousness in terms of the properties of physical objects. This is often seen mistakenly as a metaphysical problem, whereby the properties of physical things are of such a nature and so unlike mental properties that it is difficult to understand how the physical could ever explain consciousness. This view of the physical is not however the true reason for the hardness of the problem, rather it (...) is epistemic, that of defining the physical as those features of the world that may be known objectively, coupled with the contention that only those objectively known properties are real. This makes the explanation of subjective consciousness in terms physical properties not just hard but impossible. The answer is to hold that the world is indeed all physical, but have the physical no longer defined as what may be known only objectively, and hold that some physical properties may be known subjectively. This eliminates the hard problem of consciousness as it is no longer required that the explanation of subjective properties of physical things be in terms of the objective properties of physical things.

In 2016, Discourse Studies published a special issue on the ‘epistemics of epistemics’ comprising six papers, all of which took issue with a strand of my research on how knowledge claims are asserted, implemented and contested through facets of turn design and sequence organization. Apparently coordinated through some years of discussion, the critique is nonetheless somewhat confused and confusing. In this article, I take up some of more prominent elements of the critique: my work is ‘cognitivist’ substituting causal psychological analysis (...) for the classic conversation analytic focus on the normative accountability of social action, my work devalues and indeed flouts basic tenets of CA methodology such as the ‘next-turn proof procedure’, my analysis of epistemic stance introduces unwarranted themes of conflict and hostility into CA thinking, various concepts that I have introduced involve the invocation of ‘hidden orders’ of social conduct that is inimical to the traditions of our field and that my work rests on an unwarranted ‘informationism’ – the discredited idea that much of human interaction is driven by a need to traffic in information. In this rebuttal, I refute all of these commentaries and correct many other ancillary mistakes of representation and reasoning that inhabit these papers. (shrink)

A central aim of education has to do with the promotion of the pupil's and other people's well-being. Recent work by John O'Neill locates the strongest justification of the market in an individualistic preference-satisfaction notion of well-being. His own preference for an objective theory of well-being allows us to make a clear separation of educational values from those of the market. Problems in O'Neill's account suggest a third notion of well-being which better supports the separation mentioned.

"Everyone complains about what is lost in translations. This is the first account I have seen of the potentially positive impact of translation, that it represents... a genuinely new contribution." —Drew A. Hyland In his original philosophical exploration of translation, John Sallis shows that translating is much more than a matter of transposing one language into another. At the very heart of language, translation is operative throughout human thought and experience. Sallis approaches translation from four directions: from the dream (...) of nontranslation, or universal translatability; through a scene of translation staged by Shakespeare, in which the entire range of senses of translation is played out; through the question of the force of words; and from the representation of untranslatability in painting and music. Drawing on Jakobson, Gadamer, Benjamin, and Derrida, Sallis shows how the classical concept of translation has undergone mutation and deconstruction. (shrink)

Consistency is one of the key concepts of logic; logicians have put a great deal of effort into proving the consistency of many logics. Understanding what causes inconsistency is also important; some logicians have developed paraconsistent logics that, unlike classical logics, allow some contradictions without making all formulas provable. Another direction of research studies inconsistency by measuring the amount of inconsistency of sets of formulas. While the initial attempt in 1978 was too ambitious in trying to do this for first-order (...) logic, this research got a substantial boost when an inconsistency measure was proposed for propositional logic in 2002. Since then, researchers in logic and artificial intelligence have made many interesting proposals and found related issues. Almost all of this work has been done for propositional logic. The purpose of this paper is to extend inconsistency measures to logics that also contain operators, such as modal operators. We use the terminology “generalized propositional logic” for such logics. We show how to extend propositional inconsistency measures to sets of formulas in any such generalized propositional logic. Examples are used to illustrate how various modal operators, including spatial and tense operators, fit into this framework. We also show that the addition of operators leads to a weak type of inconsistency. In all cases, the calculations for several inconsistency measures are given. (shrink)
