We continue the work of [14, 3, 1, 19, 16, 4, 12, 11, 20] investigating the strength of set existence axioms needed for separable Banach space theory. We show that the separation theorem for open convex sets is equivalent to WKL 0 over RCA 0 . We show that the separation theorem for separably closed convex sets is equivalent to ACA 0 over RCA 0 . Our strategy for proving these geometrical Hahn-Banach theorems is to reduce to the finite-dimensional case (...) by means of a compactness argument. (shrink)

Despite the growing interest in Aristotelian approaches to contemporary philosophy of science, few metaphysicians have engaged directly with the question of how a neo-Aristotelian metaphysics of nature might change the landscape for theological discussion concerning theology and naturalism, the place of human beings within nature, or the problem of divine causality. The chapters in this volume are collected into three thematic sections: Naturalism and Nature, Mind and Nature, and God and Nature. By pushing the current boundaries of neo-Aristotelian metaphysics to (...) recover the traditional notion of substantial forms in physics, reframe the principle of proportionality in biology, and restore the hierarchy of being familiar to ancient philosophy, this book advances a metaphysically unified framework that accommodates both scientific and theological knowledge, enriching the interaction between science, philosophy and theology. Neo-Aristotelian Metaphysics and the Theology of Nature will be of interest to scholars and advanced students working in metaphysics, philosophy of science, natural theology, philosophical theology, and analytic theology.

The ethical dilemma of large-scale multinational corporations is presented. The list of complaints and issues is summarized. A case is made for the concept of multinationals being inherently beneficial in today's world of high technology and dependence on international trade. The difficulty is extreme power wielded by some groups. It is concluded that a philosophical ideal is for control on size and power as well as international rules to prevent abuses of power. The concern is that today the worthiness of (...) being relatively small is slowly but surely being eroded. (shrink)

This article presents a study of the discourse characteristics of interaction within a virtual community. The data are from the text-based chat forum of an online community of learners and teachers of English. The forum is the meeting place for community members, and is an international site of language use with participants from a range of linguistic backgrounds. Within this context, some pertinent themes are investigated which relate to a relatively recent form of discourse, synchronous text-based computer-mediated communication. The discussion (...) centres on the interplay between the technological attributes of the medium and the linguistic, discourse and sociocultural conditions within which the participants interact. How do these elements combine to shape the discourse? This question is addressed with reference to the cohesive feature of conversational floor. Because there is a lack of coordination of turn transfer in SCMC interaction, conversational floor emerges as an organizing principle in preference to models of conversation based on turn taking.

In a recent series of papers, Timothy Williamson argues that one can reach Edmund Gettier’s conclusion that the justified-true-belief (JTB) theory of knowledge is insufficient for knowledge by constructing Gettier cases in the framework of epistemic logic. In this paper, I argue, however, that Williamson’s Gettier cases in the framework of epistemic logic crucially turn on an assumption that the JTB theorist can plausibly and justifiably reject. In particular, I argue that it is rational for the JTB theorist to reject (...) Williamson’s preferred epistemic accessibility relation in favor of one for which Gettier cases in epistemic logic do not arise. Thus, I conclude that Williamson’s Gettier cases in epistemic logic do not genuinely threaten the tripartite theory of knowledge. (shrink)

In this paper, I develop a serious new dilemma involving necessary truths for safety-based theories of knowledge, a dilemma that I argue safety theorists cannot resolve or avoid by relativizing safety to either the subject’s basis or method of belief formation in close worlds or to a set of related or sufficiently similar propositions. I develop this dilemma primarily in conversation with Duncan Pritchard’s well-known, oft-modeled safety-based theories of knowledge. I show that Pritchard’s well-regarded anti-luck virtue theory of knowledge and (...) his recently proposed (allegedly superior) anti-risk virtue theory of knowledge clearly succumb to the dilemma, and so they are inadequate as they stand. If Pritchard’s safety-based theories of knowledge are shown to be inadequate by the dilemma that is developed in this paper, then a number of other safety-based theories of knowledge (e.g., Beddor and Pavese’s, Luper’s, Dutant’s, early Pritchard’s, and others) look to be in jeopardy in this connection as well.

A familiar anti-sceptical response (à la Sosa) to radical sceptical scenarios employs the safety of knowledge. Radical sceptical scenarios are purported to be too modally remote to really threaten knowledge of ordinary propositions. Why? Because knowledge requires safety, and safety requires the target belief to be true in all nearby possible worlds, but radical sceptical scenarios purportedly take place at distant possible worlds. Hence, the safety theorist claims that radical sceptical scenarios don’t challenge our knowledge of ordinary propositions. But it's (...) alleged by Sosa and others that there's one radical sceptical scenario that can’t be dismissed so easily: the dream scenario. After all, unlike evil demons and brains in vats, ‘dreaming is a daily part of our lives…it is too close for comfort’. In this paper, I sketch an argument to the effect that there's good reason to think that the dream of dream scepticism describes a modally remote possibility, in which case I argue that if the safety-based anti-sceptical response is successful against the evil demon sceptical scenario, the brain in a vat sceptical scenario, and other Cartesian sceptical scenarios in this mould, then it's successful against the dream sceptical scenario as well.

In a recent article, Timothy Hsiao criticizes the basic argument for moral vegetarianism. In this connection, Hsiao offers an interesting, original argument (that I'll christen Hsiao's Argument) with the conclusion that human consumption of meat solely for the purposes of nutrition trumps the welfare interests of nonhuman animals. In this article, however, I'll argue that if Hsiao's Argument isn't to be problematically circular, we have very strong grounds for thinking that it is either unsound or invalid. Toward the end of (...) this article, I'll also show that a slightly modified version of Hsiao's Argument—that I call Hsiao's Argument*—fares no better than Hsiao's Argument. So, the basic argument for moral vegetarianism looks to be in much better shape than Hsiao imagines. (shrink)

In a recent article in this journal, Calum Miller skillfully and creatively argues for the counterintuitive view that there aren’t any good reasons to believe that non-human animals feel pain in a morally relevant sense. By Miller’s lights, such reasons are either weak in their own right or they also favor the view that non-human animals don’t feel morally relevant pain. In this paper, I explain why Miller’s view is mistaken. In particular, I sketch a very reasonable abductive argument for (...) the conclusion that non-human animals feel morally relevant pain. This argument shows that, even in the face of Miller’s moderate skepticism about whether non-human animals feel pain in a morally relevant sense, it’s still more epistemically reasonable to believe that non-human animals feel pain in a morally relevant sense than not. In which case, I conclude that Miller has failed to show that there aren’t any good reasons to believe that non-human animals don’t feel pain in a morally relevant sense that don’t also count in favor of the view that non-human animals don’t feel morally relevant pain.

In a recent article in this journal, Timothy Hsiao argues that spanking a misbehaving child is morally permissible on the grounds that it's what the child deserves. However, in this short article, I argue that Hsiao's argument in this connection is either obviously unsound or invalid.

In a recent paper in this journal, Alex Grzankowski argues, contra Howard Sankey, that to believe that p isn’t to believe that p is true. In this short reply, I’ll agree with Grzankowski that to believe that p isn’t to believe that p is true, and I’ll argue that Sankey’s recent response to Grzankowski is inadequate as it stands. However, it’ll be my contention that Grzankowski’s argument doesn’t demonstrate that believing that p doesn’t require taking it to be the case (...) that p. (shrink)

Despite the challenges associated with virtually mediated communication, remote collaboration is a defining characteristic of online multiplayer gaming communities. Inspired by the teamwork exhibited by players in first-person shooter games, this study investigated the verbal and behavioral coordination of four-player teams playing a cooperative online video game. The game, Desert Herding, involved teams consisting of three ground players and one drone operator tasked to locate, corral, and contain evasive robot agents scattered across a large desert environment. Ground players could move (...) throughout the environment, while the drone operator’s role was akin to that of a “spectator” with a bird’s-eye view, with access to veridical information of the locations of teammates and the to-be-corralled agents. Categorical recurrence quantification analysis was used to measure the communication dynamics of teams as they completed the task. Demands on coordination were manipulated by varying the ground players’ ability to observe the environment with the use of game “fog.” Results show that catRQA was sensitive to changes to task visibility, with reductions in task visibility reorganizing how participants conversed during the game to maintain team situation awareness. The results are discussed in the context of future work that can address how team coordination can be augmented with the inclusion of artificial agents, as synthetic teammates. (shrink)

Readily available data are used to provide relevant decision making information on the highly subjective issue of animal rights. Two examples of alleged crowding; cattle being finished in concrete lots, and broilers in confined operations were evaluated to determine the impact on producers and consumers from increasing space per animal. It is concluded that similar policy changes, such as doubling floor space, can lead to dramatic differences in economic impact depending on the industry affected. It is shown that economic analysis (...) can provide valuable information in estimating the tradeoffs in moral issues. (shrink)

In this paper, I’ll survey a number of closure principles of epistemic justification and find them all wanting. However, it’ll be my contention that there’s a novel closure principle of epistemic justification that has the virtues of its close cousin closure principles, without their vices. This closure principle of epistemic justification can be happily thought of as a multi-premise closure principle and it cannot be used in Cartesian skeptical arguments that employ a closure principle of epistemic justification. In this way, (...) then, it represents marked improvement over other contemporary closure principles of epistemic justification that require both sacrificing multi-premise closure and forcing anti-Cartesian skeptics who reject the closure principle employed in certain Cartesian skeptical arguments to cast aside justification closure.

In a recent exchange in the pages of this journal, John Biro responds to Gabor Forrai’s argument against Biro’s argument that in most, if not all, Gettier cases the belief condition, contra popular opinion, isn’t satisfied. In this note, I’ll argue that Biro’s response to Forrai satisfactorily resolves the first of Forrai’s two central objections to Biro’s argument that the belief condition isn’t satisfied in most, if not all, Gettier cases. But Biro’s response leaves mostly unaddressed the most plausible way (...) of construing Forrai’s second objection. I’ll take up the mantle of successfully defending Biro’s argument from this more plausible construal of Forrai’s second objection. However, even though I’ll argue that Biro’s argument is in good shape with respect to Forrai’s objections, I’ll show that the definition of serious belief that Biro offers us is mistaken. (shrink)

In a recent discussion note in this journal, Moti Mizrahi offers us the following argument for the conclusion that knowledge requires epistemic certainty:1) If S knows that p on the grounds that e, then p cannot be false given e.2) If p cannot be false given e, then e makes p epistemically certain.3) Therefore, if S knows that p on the grounds that e, then e makes p epistemically certain. I’ll argue that premise 2 of Mizrahi’s argument is false, and (...) so Mizrahi’s argument is unsound. (shrink)

Fallibilism is typically taken to face a problem from the apparent infelicity of concessive knowledge attributions. CKAs are of the form: “S knows that p, but it’s possible that q,” where q obviously entails not-p. CKAs sound to the ears of many philosophers as contradictory or infelicitous. But CKAs look to be overt statements of fallibilism, since if S fallibly knows that p, then she can’t properly rule out some possibility in which not-p. Do fallibilists, then, have some way of (...) explaining the seeming infelicity of CKAs that doesn’t impugn the truth of fallibilism? Fallibilists think so. In this connection, there are two well-known responses to the problem: Patrick Rysiew’s pragmatic strategy and Jason Stanley’s semantic strategy. While both strategies have real virtues, there are aspects of each strategy that face certain complications. In this paper, I’ll outline those complications and I’ll develop some remedies to them. The aim of this paper will be to show that the challenge posed by CKAs isn’t a grave problem at all. In particular, I’ll argue that if the semantic strategy fails because CKAs really are overt statements of fallibilism, then there’s good reason to think that the pragmatic strategy succeeds, but if the pragmatic strategy fails because CKAs are obviously false or aren’t overt statements of fallibilism, then the semantic strategy succeeds. Thus, I’ll conclude that the problem for fallibilism posed by CKAs isn’t a grave problem at all. (shrink)

A 1995 study of two important late medieval poems and their philosophical and psychological contexts.

Francis Ingledew's impressive recent article in this journal argues the following: that the Trojan historiography produced by secular clerics for Norman lords and English kings is characterized by the defining features of the Virgilian philosophy of history . Even if the “Book of Troy” is “irreducible … to any single work,” Geoffrey of Monmouth's Historia regum Britanniae may be taken to be exemplary of it, since Geoffrey's “book is the effective mastertext of the new rendering of the historical field.” In (...) this article I set aside my agreement with the broad thrust of Ingledew's argument; instead I want to qualify it in two ways. In the first place, I question whether the template of the Aeneid can be used quite so straightforwardly for Galfridian material. More importantly, I question the notion of one “Troy Book.” There is another version of the “Troy Book,” that of Guido delle Colonne's Historia destructionis Troiae, translations of which constitute a significant body of English vernacular writing in the fourteenth and fifteenth centuries. This tradition is resolutely anti-imperialistic in every way. Even if works in this tradition were written for aristocratic readers, they were pitched from a clerical position that stood opposed to imperial enterprise. I make each of these points by looking back to English narratives in the Guido tradition from the vantage point of Gavin Douglas's early-sixteenth-century translation of the Aeneid, his Eneados.

The chapter examines fifty years of philosophers working on lying - from the 1970s to the current day – focusing on how lying is defined (descriptively and normatively), whether lying involves an intention to deceive (Deceptionists) or not (Non-Deceptionists), why lying is wrong, and whether lying is worse than other forms of deception, including misleading with the truth. Philosophers discussed include Roderick Chisholm and Thomas Feehan, Alan Donagan, Sissela Boy, Charles Fried, David Simpson, David Simpson, Bernard Williams, Paul (...) Faulkner, Thomas Carson, Roy Sorensen, Don Fallis, Jennifer Saul, Andreas Stoke, Jonathan Webber and Clea Rees. (shrink)

This article offers a comprehensive and critical analysis of Eric Heinze’s book Hate Speech and Democratic Citizenship (Oxford University Press, 2016). Heinze’s project is to formulate and defend a more theoretically complex version of the idea (also defended by people like Ronald Dworkin and James Weinstein) that general legal prohibitions on hate speech in public discourse compromises the state’s democratic legitimacy. We offer a detailed synopsis of Heinze’s view, highlighting some of its distinctive qualities and strengths. We then develop (...) a critical response to this view with three main focal points: (1) the characterisation of democratic legitimacy as something distinct from (and whose demands aren’t identical with those of) legitimacy per se; (2) the claim that the requirements of democracy are hypothetical, rather than categorical, imperatives; and relatedly (3) the question of how we should reconcile the requirements of democratic legitimacy with the costs that may follow from prioritising democratic legitimacy. We argue that there are significant difficulties for Heinze’s account on all three fronts. (shrink)

Gangestad & Simpson's model of the evolution of within-sex differences in reproductive strategies requires a degree of female choice that probably did not exist because of male coercion. We argue as well that the tradeoff between current and future reproduction accounts for more of the within-sex differences in reproductive strategies than the “good-genes-good parenting” tradeoff they propose.

Survey of different definitions of lying and deceiving, with an emphasis on the contemporary debate between Thomas Carson, Roy Sorensen, Don Fallis, Jennifer Saul, Paul Faulkner, Jennifer Lackey, David Simpson, Andreas Stokke, Jorg Meibauer, Seana Shiffrin, and James Mahon, among others, over whether lies always aim to deceive. Related questions include whether lies must be assertions, whether lies always breach trust, whether it is possible to lie without using spoken or written language, whether lies must always be false, (...) whether lies that are unsuccessful are still lies, and whether deception must aim at creating false beliefs as opposed to preventing people from acquiring true beliefs.

The relationship between American pragmatism and logical empiricism is complicated at best. The received view is that by around the late 1930s or early 1940s pragmatism had been replaced, supplanted, or eclipsed by the younger and more logic-oriented form of empiricism developed in interwar Vienna. Recently, however, this picture has been challenged, and this paper offers further reasons for thinking that the received view is inadequate. Through a critical examination of William James's Pragmatism and “The Sentiment of Rationality” and (...) Rudolf Carnap's “Elimination of Metaphysics Through Logical Analysis of Language” and other works, the paper builds a case for the existence of a rather striking correspondence between the work of one of pragmatism's most vaunted figures and the thought of logical empiricism's most famous advocate. Not only were both philosophers interested in what might be called metaphilosophy or the psychology of philosophy, both held very similar deflationary views. (shrink)

This article first examines a number of different definitions of lying, from Aldert Vrij, Warren Shibles, Sissela Bok, the Oxford English Dictionary, Linda Coleman and Paul Kay, and Joseph Kupfer. It considers objections to all of them, and then defends Kupfer’s definition, as well as a modified version of his definition, as the best of those so far considered. Next, it examines five other definitions of lying, from Harry G. Frankfurt, Roderick M. Chisholm and Thomas D. Feehan, David Simpson, (...) Thomas Carson, and Don Fallis. It finds reason to reject these definitions, in favor of the two definitions of lying previously defended, namely:(i) To lie (to another person) = df. to make a believed-false statement (to another person) with the intention that that statement be believed to be true (by the other person).(ii) To lie (to another person) = df. to make a believed-false statement (to another person), either with the intention that that statement be believed to be true (by the other person), or with the intention that it be believed (by the other person) that that statement is believed to be true (by the person making the statement), or with both intentions.

This paper is an investigation of the relationship between G\"odel's second incompleteness theorem and the well-foundedness of jump hierarchies. It follows from a classic theorem of Spector's that the relation $\{(A,B) \in \mathbb{R}^2 : \mathcal{O}^A \leq_H B\}$ is well-founded. We provide an alternative proof of this fact that uses G\"odel's second incompleteness theorem instead of the theory of admissible ordinals. We then derive a semantic version of the second incompleteness theorem, originally due to Mummert and Simpson, from this result. (...) Finally, we turn to the calculation of the ranks of reals in this well-founded relation. We prove that, for any $A\in\mathbb{R}$, if the rank of $A$ is $\alpha$, then $\omega_1^A$ is the $(1 + \alpha)^{\text{th}}$ admissible ordinal. It follows, assuming suitable large cardinal hypotheses, that, on a cone, the rank of $X$ is $\omega_1^X$. (shrink)

Normative judgments are typically subject to emotional reasons that cannot be justified by reference to facts alone. As a result, practical disputes sometimes go unsettled in ways that support James Lenman's view of moral inquiry as politics. An important consequence is that reasonableness is often preferable to truth as a criterion of good practical judgment. Although the role of emotions suggests metaethical expressivism as preferable to realism for analysing practical reasoning, reasonableness transforms expressivism from a form of noncognitivism into (...) a theory that recognizes cognitively rich forms of approval and disapproval. Defensible normative intuitions have good justifying reasons even when these reasons permit faultless differences of political opinion and ethical practice. Despite implying deep normative pluralism, however, a cognitivist form of expressivism explains how deliberative agents can construct and maintain reasonable moral communities. (shrink)

This work on the theory of education was first published in 1839. The five writers had been chosen as the winners in a competition for an essay on the 'Expediency and Means of Elevating the Profession of the Educator in Society', organised by the Central Society of Education, founded in 1837 to promote state funding of education, at a time when the 'monitor' system, whereby older children taught younger ones, was seen as an effective method. The journalist John Lalor won (...) first prize with a wide-ranging consideration of all the aspects of education, comparing the status of teachers through history and across several countries, and championing their 'sacred mission'. The runners-up were the writer John A. Heraud, the Unitarian minister Edward Higginson, the lawyer and author James Simpson, and Mrs Sarah Porter, prolific writer on education and sister of the political economist David Ricardo. (shrink)

An important question facing contemporary philosophy of science is whether the natural sciences in terms of their historical records exhibit distinguishing developmental patterns or structures. At least two philosophical stances are possible in answering this question. The first pertains to the plurality of the individual sciences. From this stance, the various sciences are analyzed individually and compared with one another in order to derive potential commonalities, if any, among them. The second stance involves a general philosophy of science in which (...) a thorough theory of the natural sciences is developed. The latter stance strives to account for more than possible commonalities among the sciences but also to provide a broad-spectrum philosophical framework to account for, or to explicate, the nature of science itself and its progress. In this paper, the second stance is taken in which an evolutionary philosophy of science is proposed. To that end, Thomas Kuhn’s evolutionary philosophy of science is initially discussed and critiqued. An evolutionary philosophy of science is then proposed based on a revision of Kuhn’s evolutionary philosophy of science in terms of George Gaylord Simpson’s various tempos and modes for biological evolution. Next, two historical case studies from the biological sciences are reconstructed to illustrate the robustness of the proposed evolutionary philosophy of science for explicating the progress of the natural sciences. A concluding section discusses the proposed evolutionary philosophy of science with respect to providing a broad-spectrum framework or general philosophy of science for understanding the nature and progress of the natural sciences.
