An emerging class of theories concerning the functional structure of the brain takes the reuse of neural circuitry for various cognitive purposes to be a central organizational principle. According to these theories, it is quite common for neural circuits established for one purpose to be exapted (exploited, recycled, redeployed) during evolution or normal development, and be put to different uses, often without losing their original functions. Neural reuse theories thus differ from the usual understanding of the role of neural plasticity (...) (which is, after all, a kind of reuse) in brain organization along the following lines: According to neural reuse, circuits can continue to acquire new uses after an initial or original function is established; the acquisition of new uses need not involve unusual circumstances such as injury or loss of established function; and the acquisition of a new use need not involve (much) local change to circuit structure (e.g., it might involve only the establishment of functional connections to new neural partners). Thus, neural reuse theories offer a distinct perspective on several topics of general interest, such as: the evolution and development of the brain, including (for instance) the evolutionary-developmental pathway supporting primate tool use and human language; the degree of modularity in brain organization; the degree of localization of cognitive function; and the cortical parcellation problem and the prospects (and proper methods to employ) for function to structure mapping. The idea also has some practical implications in the areas of rehabilitative medicine and machine interface design. (shrink)

A moral-pragmatic argument for a proposition is an argument intended to establish that believing the proposition would be morally beneficial. Since such arguments do not adduce epistemic reasons, i.e., reasons that support the truth of a proposition, they can seem at best to be irrelevant epistemically. At worst, believing on the basis of such reasoning can seem to involve wishful thinking and intellectual dishonesty of a sort that that precludes such beliefs from being epistemically unjustified. Inspired by an argument from (...) William James’ classic, “The Will to Believe”, I argue that there is a way of making sense of moral-pragmatic arguments such that they are epistemically relevant. I develop and argue for a theory of epistemic justification that I dub the “moral encroachment theory” (emphasizing its connection to recent pragmatic encroachment views). According to the theory, moral considerations can raise or lower epistemic standards from where they would be in morally neutral settings. The moral encroachment theory, I contend, denotes a normative property that is at once distinctively epistemic and valuable. The theory also allows a legitimate role for moral-pragmatic reasoning under certain conditions. The upshot is that moral-pragmatic reasoning can be epistemically as well as morally appropriate.

This paper presents an argument for the Principle of Sufficient Reason, the PSR, the principle according to which each thing that exists has an explanation. I begin with several widespread and extremely plausible arguments that I call explicability arguments in which a certain situation is rejected precisely because it would be arbitrary. Building on these plausible cases, I construct a series of explicability arguments that culminates in an explicability argument concerning existence itself. This argument amounts to the claim that the (...) PSR is true. The plausibility of the initial cases in the series provides the basis of an argument for the PSR, an argument that can be rebutted only by drawing a line between the plausible early cases in the series and the apparently unacceptable later cases. I argue that no principled reason for drawing this line has been found and that one cannot draw an unprincipled or arbitrary line without begging the question. The paper concludes that, therefore, this defense of the PSR remains unrebutted and that we have a powerful, new reason to embrace the PSR. (shrink)

Keith has just taken a hallucinogenic drug. A few minutes earlier, he was occupied with the beginning of H.H. Price's well-known book on perception. The combined effect of these activities is that Keith is now hallucinating a ripe tomato. This is not a de re hallucination. There is no particular tomato located elsewhere out of Keith's vision such that he is hallucinating that tomato as being before him. Keith is hallucinating a tomato without there being any particular tomato that he (...) is hallucinating. What is the representational content of Keith‟s experience? (shrink)

The complex systems approach to cognitive science invites a new understanding of extended cognitive systems. According to this understanding, extended cognitive systems are heterogenous, composed of brain, body, and niche, non-linearly coupled to one another. This view of cognitive systems, as non-linearly coupled brain–body–niche systems, promises conceptual and methodological advances. In this article we focus on two of these. First, the fundamental interdependence among brain, body, and niche makes it possible to explain extended cognition without invoking representations or computation. Second, (...) cognition and conscious experience can be understood as a single phenomenon, eliminating fruitless philosophical discussion of qualia and the so-called hard problem of consciousness. What we call “extended phenomenological-cognitive systems” are relational and dynamical entities, with interactions among heterogeneous parts at multiple spatial and temporal scales. (shrink)

Recent years have seen a vigorous revival of interest in relativism - both in support and in opposition. This collection of 21 essays, 16 of which appear in print here for the first time, advances the discussion found in an earlier volume, Relativism: Cognitive and Moral.

The contributions concern relativism in a wide range of practices in the human (...) studies. (shrink)

Predication is an indisputable part of our linguistic behavior. By contrast, the metaphysics of predication has been a matter of dispute ever since antiquity. According to Plato—or at least Platonism, the view that goes by Plato’s name in contemporary philosophy—the truths expressed by predications such as “Socrates is wise” are true because there is a subject of predication (e.g., Socrates), there is an abstract property or universal (e.g., wisdom), and the subject exemplifies the property.1 This view is supposed to be (...) general, applying to all predications, whether the subject of predication is a person, a planet, or a property.2 Despite the controversy surrounding the metaphysics of predication, many theistic philosophers—including the majority of contemporary analytic theists—regard Platonism as extremely attractive. At the same time, however, such philosophers are also commonly attracted to a form of traditional theism that has at its core the thesis that God is an absolutely independent.. (shrink)

Opinion about neonatal male circumcision is deeply divided. Some take it to be a prophylactic measure with unequivocal and significant health benefits, while others consider it a form of child abuse. We argue against both these polar views. In doing so, we discuss whether circumcision constitutes bodily mutilation, whether the absence of the child's informed consent makes it wrong, the nature and strength of the evidence regarding medical harms and benefits, and what moral weight cultural considerations have. We conclude that (...) nontherapeutic circumcision of infant boys is a suitable matter for parental discretion. (shrink)

In this article, I derive a weak version of Kant's categorical imperative within an informal game-theoretic framework. More specifically, I argue that Hobbesian agents would choose what I call the weak principle of universalization, if they had to decide on a rule of conflict resolution in an idealized but empirically defensible hypothetical decision situation. The discussion clarifies (i) the rationality requirements imposed on agents, (ii) the empirical conditions assumed to warrant the conclusion, and (iii) the political institutions that are necessary (...) to implement the derived principle. The analysis demonstrates the moral significance of the weak principle of universalization and its epistemic advantage over the categorical imperative. (shrink)

Individuals have a prima facie right to own firearms. This right is significant in view both of the role that such ownership plays in the lives of firearms enthusiasts and of the self-defense value of firearms. Nor is this right overridden by the social harms of private gun ownership. These harms have been greatly exaggerated and are probably considerably smaller than the benefits of private gun ownership. And I argue that the harms would have to be at least several times (...) greater than the benefits in order to render gun prohibition permissible. (shrink)

The basic idea of rule-utilitarianism is that right action should be defined in terms of what would be required by rules which would maximize either actual or expected utility if those rules gained general acceptance, or perhaps general compliance. Rule-utilitarians face a dilemma. They must characterize 'general acceptance' either as 100% acceptance, or as something less. On the first horn of the dilemma, rule-utilitarianism in vulnerable to the charge of utopianism; on the second, it is open to the charge of (...) arbitrariness and lack of philosophical depth. I press this objection, and develop and defend an alternative version of rule-utilitarianism which can evade the dilemma. I call this new version 'variable-rate rule-utilitarianism'. (shrink)

Human beings are essentially vulnerable in the view that their existence qua humans is not given but construed. This vulnerability receives basic protection from the State, expressed in the form of the universal rights all citizens are meant to enjoy. In addition, many individuals fall prey to destitution and deprivation, requiring social action aimed at recognising the specific harms they suffer and providing remedial assistance to palliate or remove their plights.Citizens receive protection against their biologic vulnerability by means of an (...) in rem right to health [care], which is more an attitude of protection than a specific programme. When individuals become susceptible, that is, biologically weak or diseased, they also increase their predisposition to additional harm, and require social actions to treat their demeaned condition. Such assistance takes the form of positive healthcare rights.Research on human beings has been slow to observe that the subjects recruited are susceptible, especially so if research is done in less developed countries. By mislabelling them as vulnerable – a characteristic they share with all humans – sponsors avoid registering the deprivation these people suffer, and the ethical obligation to offer them remedial help.The distinction between vulnerability and susceptibility also marks the difference between being intact but fragile – vulnerable – and being injured and predisposed to compound additional harm – susceptible. Awareness of this difference should give additional force to the rejection of double standards in research ethics. (shrink)

A great deal of attention has been paid recently to the claim that traditional Frankfurt-type counterexamples to the Principle of Alternative Possibilities (PAP), which depend for their success on the presence of a perfectly reliable indicator (or prior sign ) of what an agent will freely do if left to act on his own, are guilty of begging the question against incompatibilists, since such indicators seem to presuppose a deterministic relation between an agent’s free action and its causal antecedents. Objections (...) of this sort have given rise to considerable efforts to construct alternative Frankfurt-type counterexamples that do not rely on prior signs of this kind and so do not presuppose determinism in a way that incompatibilists should find objectionable. One consequence of this shift in the way Frankfurt-type counterexamples are formulated is that it provides an opportunity for the forceful resurgence of certain versions of the so-called flicker defense of PAP. In this paper I develop two versions of the flicker defense, indicate their advantages over other versions of this strategy, and defend them against objections. Insofar as either of these is successful, it will show not only that PAP has yet to be falsified by any of the modified Frankfurt-type counterexamples currently on offer but that cases of this sort are in principle incapable of falsifying PAP.

Michael Ruse's forthcoming book gives an enjoyable history of teleology in biology, philosophy, and theology. It argues that concepts of cause, final cause, purpose, teleology, function, design, adaptation, contrivance, progress, ends, and value have all been telescoped by most writers in those three disciplines but that these concepts (and especially the concept of design) are nonetheless valid, provided only that we recognize their metaphorical nature. I agree with this basic argument, and Ruse's critiques and historical summaries of these concepts (...) are both useful and delightful. However, I also explore one major and three minor reservations. The minor reservations are that Ruse overdoes the allegation of telescoping, does not adequately explore ways to express teleology more accurately, and erroneously denies the existence of biology–based theologians who make the same point he is making. The major reservation is that, despite all the groundwork he lays, Ruse comes to a conclusion other than the one clearly suggested by his first fourteen chapters. If he followed the evolutionary story just a bit further, to include the evolution of the human brain, he would be in a position to articulate a theologically sophisticated understanding of teleology and avoid an ending that is uncharacteristically tame.

Controversy and activism have long been linked to the subject of primate research. Even in the midst of raging ethical debates surrounding fertility treatments, genetically modified foods and stem-cell research, there has been no reduction in the campaigns of activists worldwide. Plying their trade of intimidation aimed at ending biomedical experimentation in all animals, they have succeeded in creating an environment where research institutions, often painted as guilty until proven innocent, have avoided addressing the issue for fear of becoming targets. (...) One area of intense debate is the use of primates in stroke research. Despite the fact that stroke kills more people each year than AIDS and malaria, and less than 5% of patients are candidates for current therapies, there is significant opposition to primate stroke research. A balanced examination of the ethics of primate stroke research is thus of broad interest to all areas of biomedical research. (shrink)

Since Henry Shue’s classic 1978 paper on torture, the “ticking-bomb case” has seemed to demonstrate that torture is morally justified in some moral emergencies (even if not as an institution). After presenting an analysis of torture as such and an explanation of why it, and anything much like it, is morally wrong, I argue that the ticking-bomb case demonstrates nothing at all—for at least three reasons. First, it is an appeal to intuition. The intuition is not as widely shared as (...) necessary to constitute the required demonstration. Second, the intuition is not as reliable as necessary for such a demonstration. We lack the experience that would vouch for it. And, third, Shue’s own discussion suggests that what we are intuiting (if we share Shue’s intuition) is an excuse rather than a justification. (shrink)

Should the recreational use of drugs such as marijuana, cocaine, heroin, and LSD, be prohibited by law? Prohibitionists answer yes. They usually argue that drug use is extremely harmful both to drug users and to society in general, and possibly even immoral, and they believe that these facts provide sufficient reasons for prohibition. Legalizers answer no. They usually give one or more of three arguments: First, some argue that drug use is not as harmful as prohibitionists believe, and even that (...) it is sometimes beneficial. Second, some argue that drug prohibition “does not work”, i.e., is not very successful in preventing drug use and/or has a number of very bad consequences. Lastly, some argue that drug prohibition is unjust or violates rights. I won’t attempt to discuss all these arguments here. Instead, I will focus on what seem to me the three most prominent arguments in the drug legalization debate: first, the argument that drugs should be outlawed because of the harm they cause to drug users; second, the argument that they should be outlawed because they harm people other than the user; and third, the argument that drugs should be legalized because drug prohibition violates rights. I shall focus on the moral/philosophical issues that these [134] arguments raise, rather than medical or sociological issues. I shall show that the two arguments for prohibition fail, while the third argument, for legalization, succeeds. (shrink)

Recent disclosures regarding the relationship between Heidegger’s thought and his own version of National Socialism have led me to rethink my earlier efforts to portray Heidegger as a forerunner of deep ecology. His political problems have provided ammunition for critics, such as Murray Bookchin, who regard deep ecology as a reactionary movement. In this essay, I argue that, despite some similarities, Heidegger’s thought and deep ecology are in many ways incompatible, in part because deep ecologists—in spite of their criticism of (...) the ecologically destructive character of technological modernity—generally support a “progressive” idea of human evolution.

My title1 is taken from one of the most obscure, and most discussed, sections of an already obscure and much discussed work, the discussion of the self, the world, and solipsism in sections 5.6-5.641 of Ludwig Wittgenstein’s Tractatus Logico- Philosophicus.2 Wittgenstein writes: 5.6 The limits of my language mean the limits of my world. 5.61 Logic fills the world: the limits of the world are also its limits. We cannot therefore say in logic: This and this there is in the (...) world, that there is not. For that would apparently presuppose that we exclude certain possibilities, and this cannot be the case since otherwise logic must get outside the limits of the world: that is. (shrink)

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

In "Metaphysics" Gamma 3 Aristotle declares that the philosopher investigates things that are qua things that are and that he therefore should be able to state the firmest principles of everything. The firmest principle of all is identified as the principle of non-contradiction (PNC). The main focus of Gamma 3 is Aristotle's proof for this identification. This paper begins with remarks about Aristotle's notion of the firmness of a principle and then offers an analysis of the firmness proof for PNC. (...) It focuses on some key assumptions of the proof and on the range and force of the proof. Aristotle closes Gamma 3 with the claim that PNC is ultimate in the sense that all other principles somehow rest on it. This, rather controversial, claim is given a defensible reading and shown to be central to the chapter's effort to establish PNC as the firmest principle of all. As such it completes the firmness proof and is not simply an appended remark. (shrink)

Using Aristotle's well-known sea battle as our example, we offer a precise, intelligible analysis of future contingent assertions in the presence of indeterminism. After explaining our view of the problem, we present a picture of indeterminism in the context of a tree ofbranching histories. There follows a brief description ofthe semantic bases for our double-time-reference theory of future contingents. We then set out our account. Before concluding, we discuss some ramifications of, and alternatives to, a double-time-reference approach to the problem (...) of future contingents. There are some technical ideas at the foundation of our analysis, ideas of which most philosophers are largely ignorant; on our view, in the absence of mastery ofthese ideas it is quite impossible to speak responsibly about either indeterminism or free will.

Benjamin's fragment 'Capitalism as Religion', written in 1921, was only published several decades after his death. Its aim is to show that capitalism is a cultic religion, without mercy or truce, leading humanity to the 'house of despair'. It is an astonishing document, directly based on Max Weber's Protestant Ethic and the Spirit of Capitalism, but – in ways akin to Ernst Bloch or Erich Fromm – transforming Weber's 'value-free' analysis into a ferocious anticapitalist argument, probably inspired by Gustav Landauer's (...) romantic and libertarian socialism. This article analyses Benjamin's fragment and explores its relationship to Weber's thesis, as well as to the tradition of romantic anticapitalism. (shrink)

Does Darwinism generally, and human sociobiology in particular, lead to an unwarranted (and possibly socially offensive) determinism? I argue that one must separate out different senses of determinism, and that once one has done this, a Darwinian approach to human nature can be seen to shed important light on our intuitions about free will, constraint, and control.

Under a grant from the National Science Foundation, the authors (and others) undertook to integrate ethics into graduate engineering classes at three universities—and to assess success in a way allowing comparison across classes (and institutions). This paper describes the attempt to carry out that assessment. Standard methods of assessment turned out to demand too much class time. Under pressure from instructors, the authors developed an alternative method that is both specific in content to individual classes and allows comparison across classes. (...) Results are statistically significant for ethical sensitivity and knowledge. They show measurable improvement in a single semester. (shrink)

Recent discussion in democratic theory has seen a revival of interest in pragmatism. Drawing on the work of C. S. Peirce, Cheryl Misak and Robert Talisse have argued that a form of deliberative democracy is justified as the means for citizens to assure themselves of the truth of their beliefs. In this article, I suggest that the Peircean account of deliberative democracy is conceived too narrowly. It takes its force from seeing citizens as intellectual inquirers, something that I argue is (...) both problematic in itself and relies on a controversial understanding of truth and inquiry. The article goes on to propose reasons for favouring a Deweyan rather than a Peircean account of democracy, one in which deliberation is seen not simply as a matter of arriving at the truth, but as part of a broader view of human flourishing.

The study of quantification in natural language has made remarkable progress. Quantification in natural language has been investigated extensively by philosophers, logicians, and linguists. The result has been an elegant and far-reaching theory. This article presents a survey of some of the important components of this theory. The first section presents the core of the theory of generalized quantifiers. This theory explores the range of expressions of generality in natural language, and studies some of their logical properties. The second section (...) turns to issues of how quantifiers enter into scope relations. Here there is less unanimity than in the theory of generalized quantifiers. Two basic approaches, representative of the main theories in the literature, are sketched and compared. The final section turns briefly to the general question of what a quantifier is. (shrink)

Disgust is often believed to have no special moral relevance. However, there are situations where disgust and similar feelings like revulsion, repugnance, or abhorrence function as the expression of a very strong moral disapproval that cannot fully be captured by argument. I call this kind of disgust moral disgust.Although it is always in principle possible to justify our moral disgust by explaining what it is in a given situation or action that disgusts us, the feeling of disgust often comes first (...) and either draws our attention to the fact that there is something wrong in the first place, or makes us aware that the kind of wrongness we are dealing with surpasses what can be accounted for by established moral theory. In both cases moral disgust serves an important purpose for an adequate moral evaluation of diverse situations and the actions from which they result. (shrink)

Neurotheological approaches provide an important bridge between scientific and religious perspectives. These approaches have, however, generally neglected the implications of a primordial form of spiritual healing—shamanism. Cross‐cultural studies establish the universality of shamanic practices in hunter‐gatherer societies around the world and across time. These universal principles of shamanism reflect underlying neurological processes and provide a basis for an evolutionary theology. The shamanic paradigm involves basic brain processes, neurognostic structures, and innate brain modules. This approach reveals that universals of shamanism such (...) as animism, totemism, soul flight, animal spirits, and death‐and‐rebirth experiences reflect fundamental brain operations and structures of consciousness. The shamanic paradigm can contribute to a reconciliation of scientific and religious perspectives by providing a universalistic biopsychosocial framework that explicates the biological underpinnings of spiritual experiences and practices and provides a basis for neurotheology and evolutionary theology approaches.

Is Leo Strauss truly an intellectual forebear of neoconservatism and a powerful force in shaping Bush administration foreign policy? _The Truth about Leo Strauss_ puts this question to rest, revealing for the first time how the popular media came to perpetuate an oversimplified view of a complex and wide-ranging philosopher. In doing so, it corrects our perception of Strauss, providing the best general introduction available to the political thought of this misunderstood figure. Catherine and Michael Zuckert—both former students of (...) Strauss—guide readers here to a nuanced understanding of how Strauss’s political thought fits into his broader philosophy. Challenging the ideas that Strauss was an inflexible conservative who followed in the footsteps of Nietzsche, Heidegger, and Carl Schmitt, the Zuckerts contend that Strauss’s signature idea was the need for a return to the ancients. Through their work, they conclude that Strauss was a sober defender of liberal democracy, aware of both its strengths and its weaknesses. Balanced and accessible, _The Truth about Leo Strauss_ is a must-read for anyone who wants to more fully comprehend this enigmatic philosopher and his much-disputed legacy. “_The Truth about Leo Strauss_ is the most balanced and insightful book yet written about Strauss’s thought, students, and political influence. It dispels myths promulgated by both friends and foes and persuasively traces the conflicting paths that American thinkers indebted to Strauss have taken.”—William Galston, Brookings Institution.

This paper defends an epistemic conservatism - propositional knowing-that suffices for capturing all the fine details of the knowledge of experienced nurses that depends on the complex ways in which they are embedded in shared fields of activity. I argue against the proliferation of different ways of knowing associated with the work of Dreyfus and Benner. I show how propositional knowledge can capture the detail of the phenomenology that motivates the Dreyfus/Benner proliferation.

The societal and ethical impacts of emerging technological and business systems cannot entirely be foreseen; therefore, management of these innovations will require at least some ethicists to work closely with researchers. This is particularly critical in the development of new systems because the maximum degrees of freedom for changing technological direction occurs at or just after the point of breakthrough; that is also the point where the long-term implications are hardest to visualize. Recent work on shared expertise in Science & (...) Technology Studies (STS) can help create productive collaborations among scientists, engineers, ethicists and other stakeholders as these new systems are designed and implemented. But collaboration across these disciplines will be successful only if scientists, engineers, and ethicists can communicate meaningfully with each other. The establishment of a trading zone coupled with moral imagination present one method for such collaborative communication. (shrink)
