We present a model for several early stages of the sensorimotor transformations involved in targeted arm movement. In psychophysical experiments, human subjects pointed to the remembered locations of randomly placed targets in three-dimensional space. They made consistent errors in distance, and from these errors stages in the sensorimotor transformation were deduced. When subjects attempted to move the right index finger to a virtual target they consistently undershot the distance of the more distal targets. Other experiments indicated that the error was (...) in the sensorimotor transformation rather than in the perception of distance. The error was most consistent when evaluated using a spherical coordinate system based at the right shoulder, indicating that the neural representation of target parameters is transformed from a retinocentric representation to a shoulder-centered representation. According to the model, the error in distance results from the neural implementation of a linear approximation in the algorithm to transform shoulder-centered target parameters into a set of arm orientations appropriate for placing the finger on the target. The transformation to final arm orientations places visually derived information into a frame of reference where it can readily be combined with kinesthetically derived information about initial arm orientations. The combination of these representations of initial and final arm orientations could give rise to the representation of movement direction recorded in the motor cortex by Georgopoulos and his colleagues. Later stages, such as the transformation from kinematic to dynamic parameters, or to levels of muscle activation, are beyond the scope of the present model. (shrink)

Many upper limb amputees experience an incessant, post-amputation “phantom limb pain” and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural (...) interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech “rubber hand” illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the “BairClaw” presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden.

Descartes' Meditations is one of the most thoroughly analyzed of all philosophical texts. Nevertheless, central issues in Descartes' thought remain unresolved, particularly the problem of the Cartesian Circle. Most attempts to deal with that problem have weakened the force of Descartes' own doubts or weakened the goals he was seeking. In this book, Stephen I. Wagner gives Descartes' doubts their strongest force and shows how he overcomes those doubts, establishing with metaphysical certainty the existence of a non-deceiving God and (...) the truth of his clear and distinct perceptions. Wagner's innovative and thorough reading of the text clarifies a wide range of other issues that have been left unclear by previous commentaries, including the nature of the cogito discovery and the relationship between Descartes' proofs of God's existence. His book will be of great interest to scholars and upper-level students of Descartes, early modern philosophy and theology. (shrink)

This paper spells out the implications, for Descartes's theory of ideas, of my earlier paper, "Descartes's Wax: Discovering the Nature of Mind." I show that my reading of the wax investigation provides a number of clarifications of Descartes's Meditation III discussion of ideas. My reading of Meditation III provides a ground, internal to the Meditations for Descartes's claims about objective reality, the causal laws, material falsity and the idea of God. I show that Descartes's claims and conclusions regarding these issues (...) is strengthened by the perspective I have provided. (shrink)

THIS PAPER PROVIDES A READING OF DESCARTES' COGITO WHICH RESOLVES THE PROBLEMS ENCOUNTERED BY THE OTHER PREVALENT ANALYSES OF HIS THOUGHT. I FIRST INDICATE THE WAYS IN WHICH THE INFERENTIAL AND PERFORMATIVE VIEWS FAIL TO ADEQUATELY EXPLICATE DESCARTES' OWN STATEMENTS REGARDING THE COGITO. I THEN SET OUT MY "GENERATIVE VIEW" AND SHOW THAT IT PROVIDES A FULLY CONSISTENT READING OF THESE SAME STATEMENTS. I CONCLUDE THAT THE GENERATIVE VIEW MORE ADEQUATELY REPRESENTS DESCARTES' INTENTIONS.

Descartes' procedure in "Meditation II" must be brought into line with his claim that "we must never ask about the existence of anything until we first understand its essence." And Descartes' "Meditation III" claim that he is aware of his mind's power to cause ideas must be grounded in a prior discovery of this power. Both demands are met by reading "Meditation II" as a progressive clarification of the nature of mind, with the investigation of the wax providing the discovery (...) of the mind's generative power. This process of discovery also provides the meanings of "thinking" and "existing" -- as "causing ideas" and "exercising causal power", respectively. Thus the discovery of the mind's nature also grounds the cogito. I provide a close reading of the wax investigation which supports this view. (shrink)

This chapter discusses a re-emerging topic in Cartesian scholarship—mind and body interaction. A number of thinkers, from his contemporaries onward, have maintained that Descartes' account of his two substances rules out the possibility of the interaction that he attempted to defend. Often, however, the ground for asserting this impossibility has been left less than explicit. Recent discussion has attempted to clarify the issue by asking whether there can be specified grounds within Descartes' philosophy which are sufficient to rule out mind–body (...) interaction. There are three elements of Descartes' thinking which might seem to create problems for mind–body interaction—his insistence that mind and body are absolutely distinct substances, his own restrictions on possible causal relations, and his views on the freedom of the will. Recent work has focused on the first two of these issues. The chapter's goal is to suggest that an essential element of Descartes' worldview has been overlooked in this recent discussion, and to show that once it is taken into account many of the apparent difficulties about Cartesian interaction can be resolved.

Transnational corporations have become actors with significant political power and authority which should entail responsibility and liability, specifically direct liability for complicity in human rights violations. Holding TNCs liable for human rights violations is complicated by the discontinuity between the fragmented legal/political structure of the TNC and its integrated strategic reality and the international state system which privileges sovereignty and non-intervention over the protection of individual rights. However, the post-Westphalian transition—the emergence of multiple authorities, increasing ambiguity of borders and jurisdiction (...) and blurring of the line between the public and private spheres—should facilitate imposing direct responsibility on transnational firms. Mechanisms for imposing direct responsibility on TNCs are considered including voluntary agreements and international law. However, I conclude that a hybrid public-private regime which relies on non-hierarchical compliance mechanisms is likely to be both more effective and consistent with the structure of the emerging transnational order.

The question I hope to answer is brief: What does every speaker of a natural language know? My answer is briefer still: Nothing, or at least nothing interesting. Explaining the question, and making the answer plausible, is a longer job.

Moral responsibility and morality lie at the heart of how we view the world. In our daily life, we feel responsibility-related emotions: gratitude, pride, love, forgiveness, resentment, indignation, and shame. We love those who freely and reciprocally love us. Also, we feel that people act rightly or wrongly, make the world better or worse, and are virtuous or vicious. These policies are central to our justifying how we see the world and treat others. In this book, I argue that our (...) views on these matters, except love, are false. (shrink)

This paper has three aims. First, I aim to stress the importance of the issue of the dispositional/categorical distinction in the light of the evident failure of the traditional formulation, which is in terms of conditional entailment. Second, I consider one radical new alternative on offer from Ullin Place: intentionality as the mark of the dispositional. I explain the appeal of physical intentionality, but show it ultimately to be unacceptable. Finally, I suggest what would be a better theory. If we (...) take disposition ascriptions to be functional characterizations of properties, then we can explain all that was appealing about the new alternative without the unacceptable consequences.

Wilfrid Sellars described the moral syllogism that supports the inference “I ought to do x” from “Everyone ought to do x” as a “syntactical disguise” which embodies a “mistake.” He nevertheless regarded this form of reasoning as constitutive of the moral point of view. Durkheim was the source of much of this reasoning, and this context illuminates Sellars’ unusual philosophical reconstruction of the moral point of view in terms of the collective intentions of an ideal community of rational members for (...) which the syllogism is empirically valid. The reconstruction also sheds light on the question of the status of common sense and normativity in Sellars’ naturalistic metaphysics. (shrink)

A theory of laws is developed that takes from E. J. Lowe the claim of natural laws being consistent with certain classes of exceptions. Neither abnormal cases, such as albino ravens, nor miracles falsify covering laws. This suggests that law statements cannot have the form of a universally quantified conditional. Lowe takes it that this is best explained by natural laws having normative force in the same way as moral laws and laws of the land. I argue that there is (...) a non-normative, descriptivist account that also explains the exception cases and which is preferable, given our reservations about normative laws of nature. I also suggest an improved account of miracles within the descriptivist account. (shrink)

This article offers some general criticisms of the idea that any political theory can legitimate public health interventions, and then some particular criticisms of Civic Republicanism as a political theory for public health. Civic Republicanism, I argue, legitimizes liberty-infringing public health interventions by demanding high levels of civic engagement in framing and reviewing them; to demand such engagement in pursuit of such a baseline value as health will leave insufficient civic energy for the pursuit of higher values.

The moral theory justifying punishment will shape the debate over numerous controversial issues such as the moral permissibility of the death penalty, probation, parole, and plea bargaining, as well as issues about conditions in prison and access to educational opportunities in prison. In this essay I argue that the primary goal of the criminal justice system is to inflict suffering on, and only on, those who deserve it. If I am correct, the answer to issues involving the criminal justice system (...) should be answered in large part by considering whether the practice in question furthers the infliction of suffering on, and only on, those who deserve it.

Sport is a producer of both emotional and aesthetic experiences. But how do these relate? Does a spectator’s emotional engagement in sport enhance or hinder it as an aesthetic experience? And does the aesthetic perception of sport enhance or hinder the emotional experiences? These questions will be addressed with particular reference to the distinction that can be drawn between partisan and purist watchers of sport, and making use of thinking in contemporary aesthetics and philosophy of emotion. There are some reasons (...) to think that emotion and aesthetics pull in opposite directions, in both sport and wider life. Does a purist miss out on the essence of sport if they adopt a detached aesthetic attitude? If that were the case, it would suggest that the sports spectator might have to choose between the two: experiencing one or the other but not both at the same time. Emotions and aesthetics would be a trade-off but I argue for some significant exceptions to this conclusion. (shrink)

This paper argues that an instance of trash-talking is permissible if and only if the relevant sports organization’s system of rules permits the expression. The argument for this position rests on the notion that if there is no relevant side-constraint on trash-talking, then if the player commits to a moral boundary on trash-talking then that is the moral boundary on trash-talking. I then argued that there is no relevant side-constraint on trash-talking and that the players commit to the ownership theory (...) as the moral boundary on trash-talking. Hence, the ownership theory is the moral boundary for trash-talking. I then considered a number of objections, the most important of which are that there is a side-constraint against trash-talking because it is degrading, disrespectful, exploitative, or objectifying and that the ownership theory is false because it confuses what is wrong with what is penalized.

In their paper "Why Gibbs Phase Averages Work--The Role of Ergodic Theory" (1980), David Malament and Sandy Zabell attempt to explain why phase averaging over the microcanonical ensemble gives correct predictions for the values of thermodynamic observables, for an ergodic system at equilibrium. Their idea is to bypass the traditional use of limit theorems, by relying on a uniqueness result about the microcanonical measure--namely, that it is uniquely stationary translation-continuous. I argue that their explanation begs questions about the relationship between (...) thermodynamic equilibrium and statistical equilibrium; I argue in addition that any account which supports their view of the relationship between these two notions of equilibrium will likely use the limit theorems in traditional ways, and thereby bypass the explanation they offer.

The work of Michel Foucault is not often considered in animal ethics discussions, but I believe that many of his insights can be fruitfully extended into this area of philosophical inquiry. In this paper, I present the slaughterhouse as a technology of power that is complicit in the domination and objectification of both human and nonhuman animal subjects. I begin by arguing that Foucault’s notion of an “apparatus” is a useful methodological tool for thinking about the constellation of spaces and (...) discourses in which various bodies (both human and nonhuman) find themselves enmeshed. Next, I outline Foucault’s multifaceted conceptualization of “power,” and I consider whether it makes sense to think of other animals as implicated in “power relations” in the various Foucauldian senses. Finally, I analyze a journalistic account of a contemporary slaughterhouse. Here, I argue that a variety of hierarchies (spatial, racial, species, etc.) dovetail to create an environment in which care and concern are virtually impossible. By coupling a Foucauldian analysis with certain insights developed in the bioethical work of Ralph Acampora, I offer a normative critique of an institution that has pernicious effects on both human and nonhuman animals.

What are the objects of the so-called ‘propositional attitudes’ — belief, desire, and the like? One of the best-known accounts holds them to be sentences. According to this account — which I shall call the ‘linguistic theory’ — an analysis of the logical form of a sentence like John believes that the moon is roundwill see the word ‘that’ as a hidden pair of quotation marks: except for niceties of idiom, might be written John believes ‘the moon is round’. asserts (...) that a certain relation, the ‘believes’-relation, holds between John and the sentence ‘the moon is round’.

In this reply, I raise some questions about the account of "normativity" given by Joseph Rouse. I discuss the historical form of disputes over normativity in such thinkers as Kelsen and show that the standard issue with these accounts is over the question of whether there is anything added to the normal stream of explanation by the problem of normativity. I suggest that Rouse’s attempt to avoid the issues that arise with substantive explanatory theories of practices of the kind criticized (...) in The Social Theory of Practices leads to a result that is uninformative, and the strategy raises the question of whether there is anything there to explain and thus whether there is any necessity to appeal to the kind of anomalous explanations the normativist offers. Key Words: Kelsen • normativity • Mauss • naturalism • practices. (shrink)

The ‘cultural turn’ in social thought, and the rise of interpretive modes of social analysis, have raised the issue of how social criticism can legitimately be undertaken given the central role of actors’ understandings in constituting social reality. In this article I examine this issue by exploring debates around Winch’s interpretive approach. I suggest that Winch’s arguments usefully identify problems with external criticism, that is, criticism that attempts to contrast actors’ beliefs with the social world as it really is. However, (...) I also argue that Winch’s Wittgensteinian account of rule-following, on a plausible interpretation, places excessively strong restrictions on the possibility of internal criticism. In order to show the problems with such restrictions, I critically appraise two accounts of social criticism that are compatible with Winch’s arguments, those of Pleasants and Giddens, arguing that neither offers a satisfactory analysis. I then argue that if a viable notion of internal criticism is to be established Winch’s account of rule-following needs to be rejected. Having briefly offered an alternative, I suggest that it allows a more convincing conception of internal criticism, in which the understandings of actors can be criticized on the basis of their internal contradictions. The article then attempts to meet a possible objection to this position: that the logical judgements of contradiction and coherence required for immanent critique are not cross-culturally valid. I claim that such judgements are generally valid, and develop an argument for this position based on a critique of Lukes’s arguments. (shrink)

My aim in this paper is fairly modest. I obviously do not claim that there has never been or could never be an instance of irrational or fallacious appeals to quotations from canonical sources in the marxist tradition. Instead, I claim that the practice of using quotations from canonical sources is not, as such, irrational. If we understand the epistemological infrastructure of the practice -- the rational underpinnings of it -- we can grasp how these citations appeal to the presumptive (...) authoritativeness of formulations that condense or concisely convey the core of insights that emerged from learning processes that the intellectual tradition of marxism has already traversed. The rational underpinnings of the practice include, first, the neo-Hegelian idea that we can justify a view we now hold by rationally reconstructing the insight-motivated learning process from which it emerged, and second, the convention that these rational reconstructions do not have to be elaborated in each insistence, but can be invoked in a short-form way, such as by citing the name of a decision or a concise statement of it (like a short quotation), as is common in the epistemologically similar practice of precedential reasoning in common law juridical justification. No claim is true just because of who made it; but a claim might be presumptively authoritative in cases where it was made at the end of a learning process, which has not been overtaken by a change in the circumstances or further learning.

Nonforcible adult-child sex is thought to be morally wrong in part because it is nonconsensual. In this paper, I argue against this notion. In particular, I reject accounts of the moral wrongfulness of adult-child sex that rest on the absence of consent, concerns about adult exploitation of children, and the existence of a morally primitive duty against such sex.

This paper presents an extension of Putnam's account of how substance terms such as ‘water’ and ‘gold’ function and of how a posteriori necessary truths concerning the underlying microstructures of such kinds may be derived. The paper has three aims. I aim to refute a familiar criticism of Putnam's account: that it presupposes what Salmon calls an ‘irredeemably metaphysical, and philosophically controversial, theory of essentialism’. I show how all of the details of Putnam's account—including those that Salmon believes smuggle in (...) such essentialist commitments—can be squared with a rejection of any such essentialist metaphysics. I aim to reveal why Steward is wrong to suppose that, by helping himself to the claim that ‘H2O’ is a rigid designator of a substance, Kripke, too, presupposes something controversially ‘metaphysical’. I aim to show how my proposed account also sidesteps a variety of objections raised by Needham and others who argue that Kripke's and Putnam's accounts of how ‘water’ and.. (shrink)

The compensatory‐justice justification of affirmative action requires a comparison of the actual world in which the injured person lives with a relevantly similar possible world in which this person lives but where the unjust injuring act never occurred, in order to identify the degree of harm brought about by the unjust injurious act. The problem is that some unjust injuring acts, particularly acts of slavery, led to intercourse and the later creation of the ancestors of many members of minority groups. (...) Hence, there is no possible world in which these individuals exist and in which the injustice, e.g., slavery, did not occur. As a result, the counterfactual test does not allow us to measure or even understand the existence of a compensatable injury to these persons. I provide an inheritance‐based account of compensation that escapes this. (shrink)

I will offer a defence of Anselm's Ontological Argument, building on some suggestions made by Prior. The defence offered avoids one of the objections commonly levelled against the Ontological Argument. I will not consider whether the use of this objection involves a misinterpretation of the argument as put forward by Anselm. It might, for example, be held that the argument of Proslogion 2 is programmatic, and points forward to Prosiogion 3, and arguments given by Anselm in his Reply to Gaunilo. (...) In particular it might be denied that Anselm holds that what is greater about what exists in reality is just that it exists in reality. While what I have to say will start from points made by Prior, I do not intend to suggest that Prior holds that there is a defence possible for Anselm's argument such as I will offer. What I have to say involves emphasizing modal notions, and treating Anselm's argument as a modal argument. Thus it comes down to defending Anselm's argument in Proslogion 3 in preference to the Proslogion 2 argument. (shrink)

The analytic philosophy form of the problem of collective intentionality originated with the claim that individual statements of the form “I intend x” cannot add up to a “we intend x” statement. Analytic philosophers from Wilfrid Sellars on have pursued a strategy that construes these sentences as individual tellings of statements whose form is collective. The point of the strategy is to avoid the problematic idea of a real collective subject. This approach creates unusual epistemic problems. Although“telling” of collective intentions (...) is parallel to the expression of individual intention, one can be deceived about them. I suggest that none of the supposed evidence could solve the problem of deception, because there is no fact of the relevant kind to be deceived about. I also argue that this strategy is unnecessary. Statements like Joe Namath’s “guarantee” of victory in the Superbowl are model non-collective statements which are interchangeable with many supposed collective statements. Yet, no novel mode of “telling” and nothing epistemically anomalous is required by this statement. The statement is merely an individual statement conditional on a variety of facts, which happen to include facts about other people, whose only commitments are epistemic. Sellars’s problem structure is then itself critiqued to suggest that it confuses a grammatical problem with a factual-theoretical problem about the reality of collectivities and the cognitive character of intention attributions, and further confuses collective intentionality with a problem about the nature of morality.

This article evaluates the structural conception of interests developed by Margaret Archer as part of her dualist version of critical realism. It argues that this structural analysis of interests is untenable because, first, Archer’s account of the causal influence of interests on agents is contradictory and, second, Archer fails to offer a defensible account of her claim that interests influence agents by providing reasons for action. These problems are explored in relation to Archer’s theoretical and empirical work. I argue for (...) an alternative account of interests that focuses on agents’ understandings of their interests and problems with these understandings. (shrink)

This Comment argues that Stephen Bush's critique of Georges Bataille's meditative practice fails to recognize how the disruption of the self, and the challenge to goal-oriented activity that comprise the heart of that practice, serve as an ethical limit that protects against sadistic and violent engagement with the world. The ethical disposition fostered by Bataille's practice is a dissolution of the self. In this reply to Kent Brintnall's response to my essay on Georges Bataille and the ethics of ecstasy, (...) I explore two primary questions: whether instrumentalization is inherently violent and non-instrumentalization is inherently non-violent, and whether there is a way to intervene in the world that avoids both "apathetic disengagement" and domination. I endorse the view that instrumentalization can be good as well as bad, and I suggest that it is possible to strive to intervene in the world without striving to master it. I make reference to Sarah Coakley as a Christian theologian who advances particular practices that aim for non-dominating intervention in theworld. (shrink)

Space warfare is warfare that takes place in outer space. It involves ground-to-space, space-to-ground, and space-to-space violence between nations or peoples. The violence can involve kinetic weapons, directed energy weapons, or electronic destruction. International law, specifically, the Outer Space Treaty and SALT I, currently bans weapons of mass destruction from being put into space, although one wonders if one country were to violate the ban whether others would follow suit. In this paper, I argue that that if there is a (...) non-consequentialist morality of space war, then one country can unjustly attack a second country’s space vehicles. This in turn depends on property rights. But there is no adequate theory of property rights with regard to space war. Hence, there is no non-consequentialist morality of a space war. (shrink)

1. IntroductionSuch is the depth and breadth of Peter van Inwagen’s philosophical output, one must pick and choose which topics to cover when editing a book exploring the philosophical themes touched upon in his work. In Being, Freedom and Method,1 John Keller has brought together several excellent philosophers to explore four such themes – being, freedom, method, and God (the last of which doesn’t make it into the title of the book, perhaps because doing so would violate the rule that (...) the title of a work of analytic philosophy must list exactly three things). Keller does a fine job of covering many of the topics that have interested van Inwagen over the years, but he cannot cover them all (I am most sad to see no substantive treatment of van Inwagen’s work on composition and mereology). Van Inwagen, in his afterword, also finds it necessary to pick and choose which papers he responds to – he addresses only seven of the sixteen papers in the book. I too must pick and choose. In what follows, I shall briefly describe the contents of the book, then make more substantive comments on some of the papers (those about which I think I have something interesting to say).

This review article argues that John Kieschnick’s Buddhist Historiography in China (2022) constitutes a landmark in the field. The book covers a large swath of original sources, analyzes authorial strategies, and assesses the place of writing about the Buddhist past within the Sinocentric tradition of court-focused historiography. I point up the strengths of the book, identify its most significant chapters, and probe its interpretation of Buddhist historiography. I also suggest that, by including a broader range of genres within the ambit (...) of Buddhist historiography, future scholarship might add perspectives that diverge from those of the centralized state and the Saṃgha.

I’m going to argue for something that some of you will find repugnant but which I can’t help thinking may be true—namely, that there are no determinate moral truths. As will become apparent, my interest in moral discourse as manifested in this paper derives more than a little from my interest in the theory of meaning. Moral discourse has always presented a puzzle for the theory of meaning and philosophical logic, and I take myself to be following the advice of (...) Bertrand Russell when he recommended testing philosophical theories by their capacity to deal with puzzles, “since these serve much the same purpose as is served by experiments in physical science.” Section (1) offers an epistemological argument for the claim that there are no determinate moral truths. This argument raises further questions, which subsequent sections try to answer. In the course of answering those further questions, another, non-epistemological, argument is offered for the claim that there are no determinate moral truths. In the end, I hope we see not only that there are no determinately true moral propositions, but what it is about moral concepts which makes that so. (shrink)

In this paper, I consider the debate between moral individualists and those whose moral philosophy is influenced by Wittgenstein, and in particular the extent to which its participants appear to be talking past one another. In the hope of illuminating, and perhaps alleviating, this mutual incomprehensibility, I demonstrate the pervasive reliance of these Wittgensteinian opponents of moral individualism upon the moral testimony of others, and the ways in which that reliance reflects a central element of the commitment to which that (...) testimony testifies—the moral significance of being human. I argue that this internal relation between the form and the content of these anti-individualist texts is what makes it so difficult for their opponents to grasp their significance, and at the same time renders them vulnerable to the charge of moralism.
