We make three points: (1) Overlooked studies of nonhuman communication originally inspired, but no longer support, the blinkered view of mental continuity that Penn et al. critique. (2) Communicative discontinuities between animals and humans might be rooted in social-cognitive discontinuities, reflecting a common lacuna in Penn et al.'s relational reinterpretation mechanism. (3) However, relational reinterpretation need not be a qualitatively new representational process.

Asperó and Schindler have completely solved the Axiom [Formula: see text] vs. [Formula: see text] problem. They have proved that if [Formula: see text] holds then Axiom [Formula: see text] holds, with no additional assumptions. The key question now concerns the relationship between [Formula: see text] and Axiom [Formula: see text]. This is because the foundational issues raised by the problem of Axiom [Formula: see text] vs. [Formula: see text] arguably persist in the problem of Axiom [Formula: see text] vs. (...) [Formula: see text]. The first of our two main theorems is that Axiom [Formula: see text] is equivalent to Axiom [Formula: see text], and as a corollary we show that Axiom [Formula: see text] fails in all the known models of [Formula: see text]. This suggests that [Formula: see text] actually refutes Axiom [Formula: see text]. Our second main theorem is that the [Formula: see text] Conjecture holds assuming [Formula: see text]. This is the strongest partial result known on this conjecture which is one of the central open problems of [Formula: see text]-theory and [Formula: see text]-logic. These results identify a fundamental asymmetry between the Continuum Hypothesis and any axiom which is both [Formula: see text]-expressible and which implies [Formula: see text], on the basis of generic absoluteness for the simplest of the nontrivial sentences of Third-Order Number Theory. These are the [Formula: see text]-sentences with no parameters. Such sentences are those which simply assert the existence of a set [Formula: see text] for which some property involving only quantification over [Formula: see text] holds. (shrink)

In The Ethics of Discernment, Patrick H. Byrne presents an approach to ethics that builds upon the cognitional theory and the philosophical method of self-appropriation that Bernard Lonergan introduced in his book Insight, as well as upon Lonergan's later writing on ethics and values. Extending Lonergan's method into the realm of ethics, Byrne argues that we can use self-appropriation to come to objective judgements of value. The Ethics of Discernment is an introspective analysis of that process, in which sustained ethical (...) inquiry and attentiveness to feelings as "intentions of value" leads to a rich conception of the good. Written both for those with an interest in Lonergan's philosophy and for those interested in theories of ethics who have only a limited knowledge of Lonergan's work, Byrne's book is the first detailed exposition of an ethical theory based on Lonergan's philosophical method.

Codes of ethics currently offer no guidance to scientists acting in capacity of expert. Yet communicating their expertise is one of the most important activities of scientists. Here I argue that expert communication has a specifically ethical dimension, and that experts must face a fundamental trade-off between "actionability" and "transparency" when communicating. Some recommendations for expert communication are suggested.

In these essays, Hugh J. McCann develops a unified perspective on human action. Written over a period of twenty-five years, the essays provide a comprehensive survey of the major topics in contemporary action theory. In four sections, the book addresses the ontology of action ; the foundations of action ; intention, will, and freedom; and practical rationality. McCann works out a compromise between competing perspectives on the individuation of action ; explores the foundations of action and defends a volitional (...) theory; argues for a libertarian view of both the formation and the execution of intention; and considers the question of consistency in rational intentions, as well as the relationship between practical and theoretical reasoning. -/- Among the original features of McCann's work are his defense of both fine- and coarse-grained actions and his arguments for a noncausal theory of the relation between intention and action. He also suggests that intentions need not be consistent, either with each other or with beliefs about success. And he contends that intention formation is an intrinsically ratiocinative procedure, distinct from reasoning about what action would be best. (shrink)

This book takes a look at American educational history and focuses on the collaboration between teachers, policymakers, philosophers, and activists.

I hold no view as to what actions are basic, but I shall attempt to show in what follows that actions like raising an arm never are. My contention is that these actions involve actions of physical exertion on the part of the agent, the involvement being of a sort generally taken to be excluded by an actions being basic.

Five leading figures in the philosophy of mind and cognitive science debate the central topic of mental representation. Each author's contribution is specially written for this volume, and then collectively discussed by the others. The editor frames the discussions and provides a way into the debates for new readers. An exciting feature of this collection is the transcribed discussion among all the contributors following each exchange. This is the latest thinking on mental representation carefully and critically analysed by the leading (...) thinkers in the field. (shrink)

Biologists explain organisms’ behavior not only as having been programmed by genes and shaped by natural selection, but also as the result of an organism’s agency: the capacity to react to environmental changes in goal-driven ways. The use of such ‘agential explanations’ reopens old questions about how justified it is to ascribe agency to entities like bacteria or plants that obviously lack rationality and even a nervous system. Is organismic agency genuinely ‘real’ or is it just a useful fiction? In (...) this paper we focus on two questions: whether agential explanations are to be interpreted ontically, and whether they can be reduced to non-agential explanations (thereby dispensing with agency). The Kantian approach we identify interprets agential explanations non-ontically, yet holds agency to be indispensable. Attributing agency to organisms is not to be taken literally in the way we attribute physical properties such as mass or acceleration, but nor is it a mere heuristic or predictive tool. Rather, it is an inevitable consequence of our own rational capacity: as long as we are rational agents ourselves, we cannot avoid seeing agency in organisms. (shrink)

ABSTRACT Biomedical experimentation on animals is justified, researchers say, because of its enormous benefits to human beings. Sure, animals suffer and die, but that is morally insignificant since the benefits of research incalculably outweigh the evils. Although this utilitarian claim appears straightforward and relatively uncontroversial, it is neither straightforward nor uncontroversial. This defence of animal experimentation is likely to succeed only by rejecting three widely held moral presumptions. We identify these assumptions and explain their relevance to the justification of animal (...) experimentation. We argue that, even if non‐human animals have considerably less moral worth than humans, experimentation is justified only if the benefits are overwhelming. By building on and expanding on arguments offered in earlier papers, we show that researchers cannot substantiate their claims on behalf of animal research. We conclude that there is currently no acceptable utilitarian defence of animal experimentation. Moreover, it is unlikely that there could be one. Since most apologists of animal experimentation rely on utilitarian justifications of their practice, it appears that biomedical experimentation on animals is not morally justified. (shrink)

It is a little understood fact that the system of formal logic presented in Wittgenstein?s Tractatusprovides the basis for an alternative general semantics for a predicate calculus that is consistent and coherent, essentially independent of the metaphysics of logical atomism, and philosophically illuminating in its own right. The purpose of this paper is threefold: to describe the general characteristics of a Tractarian-style semantics, to defend the Tractatus system against the charge of expressive incompleteness as levelled by Robert Fogelin, and to (...) give a semantics for a formal language that is the Tractarian equivalent of a first-order predicate calculus. Of note in regard to the latter is the fact that a Tractatusstyle truth-definition makes no appeal to the technical trick of defining truth in terms of the satisfaction of predicates by infinite sequences of objects, yet is materially equivalent to the usual Tarski-style truth-definitions.

The first book to explore the philosophical foundations of labour law in detail, including topics such as the meaning of work, the relationship between employee and employer, and the demands of justice in the workplace.

Philosophers of science and metascientists alike typically model scientists’ behavior as driven by credit maximization. In this article I argue that this modeling assumption cannot account for how scientists have a default level of trust in each other’s assertions. The normative implication of this is that science policy should not focus solely on incentive reform.

A model of interreligious theology that seeks to reconcile the ideal of religious tolerance with an acknowledgement of the extent to which religious communities construct identity on the basis of religious differences.

This article examines the emergence of the Nyāya distinction between vāda and jalpa as didactic-scientific and agonistic-sophistical forms of debate, respectively. Looking at the relevant sutras in Gautama’s Nyāya-sūtra (NS 1.2.1-3) in light of the earlier discussion of the types of debate in Caraka Saṃhitā 8, the article argues that certain ambiguities and obscurities in the former text can be explained on the hypothesis that the early Nyāya presupposed an agonistic understanding of vāda similar to what we find in Caraka.

The results of this paper concern the effective cardinal structure of the subsets of [ω1]<ω1, the set of all countable subsets of ω1. The main results include dichotomy theorems and theorems which show that the effective cardinal structure is complicated.

Perceptual learning involves an improvement in perceptual judgment with practice, which is often specific to stimulus or task factors. Perceptual learning has been shown on a range of visual tasks but very little research has explored chromatic perceptual learning. Here, we use two low level perceptual threshold tasks and a supra-threshold target detection task to assess chromatic perceptual learning and category effects. Experiment 1 investigates whether chromatic thresholds reduce as a result of training and at what level of analysis learning (...) effects occur. Experiment 2 explores the effect of category training on chromatic thresholds, whether training of this nature is category specific and whether it can induce categorical responding. Experiment 3 investigates the effect of category training on a higher level, lateralized target detection task, previously found to be sensitive to category effects. The findings indicate that performance on a perceptual threshold task improves following training but improvements do not transfer across retinal location or hue. Therefore, chromatic perceptual learning is category specific and can occur at relatively early stages of visual analysis. Additionally, category training does not induce category effects on a low level perceptual threshold task, as indicated by comparable discrimination thresholds at the newly learned hue boundary and adjacent test points. However, category training does induce category effects on a supra-threshold target detection task. Whilst chromatic perceptual learning is possible, learnt category effects appear to be a product of left hemisphere processing, and may require the input of higher level linguistic coding processes in order to manifest.

I argue that the reference for “God” is determined by the definite description “the being that is worthy of our worship.” I describe two desiderata for rival theories of the reference of “God” to meet: accessibility and scope. I explain the deficiencies of a view where God is dubbed “God” and the name passed down by causal chains and a view where “God” picks out the unique satisfier of a traditional definite description. After articulating the “Worship-Worthiness” view, I show how (...) it best satisfies the desiderata. I then respond to some putative counterexamples to the view. (shrink)

Contemporary argumentation theory has developed an impressive array of norms, goals and virtues applicable to ideal argument. But what is the moral status of these prescriptions? Is an interlocutor who fails to live up to these norms guilty of a moral failing as well as an epistemic or cognitive error? If so, why? In answering these questions, I argue that deliberation’s epistemic and cognitive goods attach to important ethical goods, and that respect for others’ rationality, the ethics of joint action, (...) and the importance of consensus join forces with these goods to provide strong reasons for cleaving to high standards of argument. I sketch an illustrative continuum of argument practices of different deliberative-cum-ethical standards, and consider how one should ethically respond when faced with an interlocutor employing less than ideal standards.

“Meta-argument allegations” consist of protestations that an interlocutor’s speech is wrongfully offensive or will trigger undesirable social consequences. Such protestations are meta-argument in the sense that they do not interrogate the soundness of an opponent’s argumentation, but instead focus on external features of that argument. They are allegations because they imply moral wrongdoing. There is a legitimate place for meta-argument allegations, and the moral and epistemic goods that can come from them will be front of mind for those levelling such (...) allegations. But I argue there is a dark side to such allegations, and their epistemic and moral costs must be seriously weighed. Meta-argument allegations have a concerning capacity to derail discussions about important topics, stymieing argumentational interactions and the goods they provide. Such allegations can license efforts to silence, punish and deter—even as they provoke the original speaker to retaliate in kind. Used liberally, such allegations can escalate conflicts, block open-mindedness, and discourage constructive dialogues. In response, I defend “argumentational tolerance”—a principled wariness in employing meta-argument allegations—as a virtue of ethical argument. (shrink)

The challenge this book addresses is to demonstrate how, in teaching content knowledge, the development of intellectual and moral dispositions as virtues is not merely a good idea, or peripheral to that content, but deeply embedded in the logic of searching for knowledge and truth. It offers a powerful example of how philosophy of education can be brought to bear on real problems of educational research and practice – pointing the reader to re-envision what it means to educate children by (...) developing the person, instead of simply knowledge and skills. Connected intimately to the practice of teaching and teacher education, the book sets forth an alternative theory of education where the developing person is at the center of education set in a moral space and a political order. To this end, a framework of public and personal knowledge forms the content, to which personal dispositions are integral, not peripheral. The book’s pedagogy is invitational, welcoming its readers as companions in inquiry and thought about the moral aspects of what we teach as knowledge. (shrink)

Recent investigations have thrown new light on such topics as the early Greek belief in heliocentricity, the relation between Greek and Babylonian astronomy, the reliability of Ptolemy's Syntaxis, Hipparchus's theory of motion for the sun, Hipparchus's value for the obliquity of the ecliptic, and Eratosthenes' estimate of the size of the earth. Some claims resulting from these investigations are controversial, especially the reevaluation of Ptolemy (though it is notable that no one any longer uses data from the Syntaxis for investigating (...) such things as the spin of the earth). This essay presents the evidence for these claims; it makes no pretense of presenting the evidence against them. (shrink)
