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)
Voles are attracting attention because genetic variation at a single locus appears to have a profound impact on a complex social behavior, namely monogamy. After briefly reviewing the state of the most relevant scientific literature, I examine the way that this research gets taken up by the popular media, by scientists, and by the notable philosopher of neuroscience Patricia Churchland and interpreted as having deeply revisionary implications for how we ordinarily understand ourselves as persons. We have all these big (...) questions we would like to resolve about free will, consciousness, our understanding of persons, and the nature of morality and there is a tendency to ask more of neuroscience than it can yet answer. I do not deny that advances in neuroscience may eventually bear on important philosophical issues. However, it is not at all clear that this research has many of the sweeping implications being claimed for it and, in communicating science responsibly to the public, there is reason to be cautious about suggesting that it does.

This review describes central difficulties in the interdisciplinary study of dreaming, summarizes Jouvet's account of his role in the history of modern dream science, queries his positive speculations on the semantics of dreaming, and suggests work for historians of neuroscience.
Are experience and stimulus necessarily alike? Wertheimer spoke of this as an “insidious and insistent belief”. By contrast, Watson devotes an entire book to the defense of the thesis that representation necessarily requires resemblance. I argue that this bold and important thesis is ambiguous between a historical and a systematic reading, and that in either one of these readings the thesis, for different reasons, will be found wanting. Second, a proper evaluation of it in either one of its possible interpretations (...) requires a careful analysis of the notion of resemblance. I proceed to supply some necessary distinctions and argue that, given such an analysis, Watson's thesis may be historically applicable only to ancient and medieval philosophy, while its systematic import is untenable.

This collection of essays by philosophers and educationalists of international reputation, all published here for the first time, celebrates Paul Hirst's professional career. The introductory essay by Robin Barrow and Patricia White outlines Paul Hirst's career and maps the shifts in his thought about education, showing how his views on teacher education, the curriculum and educational aims are interrelated. Contributions from leading names in British and American philosophy of education cover themes ranging from the nature of good teaching to (...) Wittgensteinian aesthetics. The collection concludes with a paper in which Paul Hirst sets out his latest views on the nature of education and its aims. The book also includes a complete bibliography of works by Hirst and a substantial set of references to his writing. (shrink)
This paper replies to an argument due to Greenspan (1980) and to Morton (2002) against the view that emotions are perceptions of values. The argument holds that this view cannot make room for ambivalent emotions both of which are appropriate, such as when it is appropriate to feel fear and attraction towards something. This would make for a contradiction, for appropriate emotions are supposed to present things as they are. The problem, I argue, is that this line of thoughts forgets (...) that things can have positive and negative aspects: something can both be dangerous and attractive, for instance. (shrink)
Any study of the 'Scientific Revolution' and particularly Descartes' role in the debates surrounding the conception of nature (atoms and the void v. plenum theory, the role of mathematics and experiment in natural knowledge, the status and derivation of the laws of nature, the eternality and necessity of eternal truths, etc.) should be placed in the philosophical, scientific, theological, and sociological context of its time. Seventeenth-century debates concerning the nature of the eternal truths such as '2 + 2 = 4' (...) or the law of inertia turn on the question of whether these truths were created along with nature, or were uncreated and subsisting in God's mind. One's answer to that question has direct consequences for conceptions of the necessity/contingency of mathematical and natural knowledge, how knowledge of such truths is accomplished by humans, and what grounds these truths. In this paper, I review the positions of four successors to Descartes' philosophy on the question of the eternal truths to illustrate how in specific ways that question with its theological, metaphysical, modal, and epistemological dimensions concerned the objectivity and certainty of the discoveries of the new science.

I require students to post a short paragraph in response to the question or some posting by a classmate on the question. Students are required to post by 10 a.m. the day before we meet for class on a course website. Week 1: According to Descartes, what role does skepticism play in scientific reasoning? Week 2: Comment on the following: 'But I am supposing this machine to be made by the hands of God, and so I think you may reasonably think it capable of a greater variety of movements than I could possibly imagine in it, and of exhibiting more artistry than I could possibly ascribe to it' [ Treatise on Man ; ATXI 120]. Week 3: What is Descartes' conception of the relation between the metaphysics and physics of nature? Week 4: Critically discuss the positions of Descartes, Malebranche, and Leibniz on what provides the foundation for the certitude of natural knowledge? Week 5: Explain why both Malebranche and Leibniz consider moral sin to be analogous to natural defect? Seminar/Project Idea Hold a debate on the question of the status of the eternal truths. The proposition will be Descartes' position: 'Eternal truths must be both created and necessary if certainty in science is to be possible'. Format: 1. At the beginning of the 5-week module, students will be assigned to one of three roles: Team A, Team B, and judge's panel. Students will be given the debate proposition, but will not be told which team will take the affirmative and which team the negative until the time of the debate. 2. Recommend a variation on the Classic Debate Format to encourage the development of argument: sequence begins with affirmative construction (8 minutes), negative construction (8 minutes), second affirmative construction (8 minutes), second negative construction (8 minutes), first negative rebuttal (4 minutes), first affirmative rebuttal (4 minutes), final negative rebuttal (4 minutes) and final affirmative rebuttal (4 minutes). 3. Judges Panel: will consist of 3–4 judges who will assess the performance of Teams A and B. Judgment should be based on the persuasiveness of the team position. 4. Debate will be held at the end of the fifth week, or semester, whichever makes most sense given the course length and structure.

Gray zones, which develop wherever oppression is severe and lasting, are inhabited by victims of evil who become complicit in perpetrating on others the evils that threaten to engulf themselves. Women, who have inhabited many gray zones, present challenges for feminist theorists, who have long struggled with how resistance is possible under coercive institutions. Building on Primo Levi's reflections on the gray zone in Nazi death camps and ghettos, this essay argues that resistance is sometimes possible, although outsiders are rarely, (...) if ever, in a position to judge when. It also raises questions about the adequacy of ordinary moral concepts to mark the distinctions that would be helpful for thinking about how to respond in a gray zone. (shrink)
Ramsey Eric Ramsey, The Long Path to Nearness: A Contribution to a Corporeal Philosophy of Communication and the Groundwork for an Ethics of Relief (reviewed by Patricia Huntington).
For the last 100 years historians have denigrated the psychology of the Critique of Pure Reason. In opposition, Patricia Kitcher argues that we can only understand the deduction of the categories in terms of Kant's attempt to fathom the psychological prerequisites of thought, and that this investigation illuminates thinking itself. Kant tried to understand the "task environment" of knowledge and thought: Given the data we acquire and the scientific generalizations we make, what basic cognitive capacities are necessary to perform (...) these feats? What do these capacities imply about the inevitable structure of our knowledge? Kitcher specifically considers Kant's claims about the unity of the thinking self; the spatial forms of human perceptions; the relations among mental states necessary for them to have content; the relations between perceptions and judgment; the malleability essential to empirical concepts; the structure of empirical concepts required for inductive inference; and the limits of philosophical insight into psychological processes.

Fox, Patricia Any study of recent publications, the statistics from diocesan websites and the litanies of anecdotal evidence reveals that the Church in Australia is at present being confronted by some very serious pastoral realities.1 In the face of this, I want to suggest that Vatican II's teaching on the call to holiness can open new pathways for the church by offering a significant challenge to the still widespread assumption among Catholics that God's call belongs only to a select (...) few. I want to propose that a restored and renewed theology of vocation needs to be a crucial element within the church's response to the serious pastoral situations confronting us. I will begin with the teaching on the call to holiness in Lumen Gentium, trace some developments towards a renewed pneumatology and theology of vocation that occurred in the wake of the conciliar teaching on holiness, and then consider briefly the creative impact of this on a theology of ministry and ministerial practice. I want to argue that there is an urgent pastoral necessity in this country for the leadership of the church, universal and local, to receive and enact the church's teaching on being called and sent.

As neuroscience uncovers these and other mechanisms regulating choices and social behaviour, we cannot help but wonder whether anyone truly chooses anything (though see "Is the universe deterministic?"). As a result, profound questions about responsibility are inescapable, not just regarding criminal justice, but in the day-to-day business of life. Given that, I suggest that free will, as traditionally understood, needs modification. Because of its importance in society, any description of free will updated to fit what we know about the nervous (...) system must also reflect our social need for a working concept of responsibility. (shrink)
I was led to this clarificatory job initially by some puzzlement from a philosopher's standpoint about just why free will questions should come up particularly in connection with the genome project, as opposed to the many other scientific research programs that presuppose determinism. The philosophic concept of determinism involves explanation of all events, including human action, by prior causal factors--so that whether or not human behavior has a genetic basis, it ultimately gets traced back to _something_ true of the world (...) before our birth. The philosophic problem of free will and determinism arises because this seems to undercut moral responsibility: How can we reasonably be held responsible for something whose causes we couldn't control?

A dialogue between virtue and care ethics is formed as a step towards meeting Pellegrino's challenge to create a more comprehensive moral philosophy. It is also a dialogue between nursing and medicine since each practice draws on the Greek Virtue Tradition and the Judeo-Christian Tradition of care differently. In the Greek Virtue Tradition, the point of scrutiny lies in the inner character of the actor, whereas in the Judeo-Christian Tradition the focus is relational, i.e. how virtues are lived out in (...) specific relationships, particularly unequal relationships where vulnerability of one of the members is an issue. In a care ethic relational qualities such as attunement rather than inner qualities are the point of scrutiny. A dialogue between these two traditions makes it possible to consider the relational virtues and skills of openness and responsiveness that are required for a respectful meeting of the other.

It is now a platitude that sexual objectification is wrong. As is often pointed out, however, some objectification seems morally permissible and even quite appealing—as when lovers are so inflamed by passion that they temporarily fail to attend to the complexity and humanity of their partners. Some, such as Nussbaum, have argued that what renders objectification benign is the right sort of relationship between the participants; symmetry, mutuality, and intimacy render objectification less troubling. On this line of thought, pornography, prostitution, (...) and some kinds of casual sex are inherently morally suspect. I argue against this view: what matters is simply respect for autonomy, and whether the objectification is consensual. Intimacy, I explain, can make objectification more morally worrisome rather than less, and symmetry and mutuality are not relevant. The proper political and social context, however, is crucial, since only in its presence can consent be genuine. I defend the consent account against the objection that there is something paradoxical in consenting to objectification, and I conclude that given the right background conditions, there is nothing wrong with anonymous, one-sided, or just-for-pleasure kinds of sexual objectification.

Philosophy, in its traditional guise, addresses questions where experimental science has not yet nailed down plausible explanatory theories. Thus, the ancient Greeks pondered the nature of life, the sun, and tides, but also how we learn and make decisions. The history of science can be seen as a gradual process whereby speculative philosophy cedes intellectual space to increasingly wellgrounded experimental disciplines—first astronomy, but followed by physics, chemistry, geology, biology, archaeology, and more recently, ethology, psychology, and neuroscience. Science now encompasses plausible (...) theories in many domains, including large-scale theories about the cosmos, life, matter, and energy. The mind’s turn has now come. The classical ‘‘mind’’ questions center on free will, the self, consciousness, how thoughts can have meaning and ‘‘aboutness,’’ and how we learn and use knowledge. All these matters interlace with questions about morality: where values come from, the roles of reason and emotion in choice, and the wherefore of responsibility and punishment. The vintage mind/body problem is a legacy of Descartes: if the mind is a completely nonphysical substance, as he thought, how can it interact causally with the physical brain? Since the weight of evidence indicates that mental processes actually are processes of the brain, Descartes’ problem has disappeared. The classical mind/ body problem has been replaced with a range of questions: what brain mechanisms explain learning, decision making, self-deception, and so on. The replacement for ‘‘the mind-body problem’’ is not a single problem; it is the vast research program of cognitive neuroscience. The dominant methodology of philosophy of mind and morals in the twentieth.. (shrink)
Within the domain of philosophy, it is not unusual to hear the claim that most questions about the nature of consciousness are essentially and absolutely beyond the scope of science, no matter how science may develop in the twenty-first century. Some things, it is pointed out, we shall never _ever_ understand, and consciousness is one of them (Vendler 1994, Swinburne 1994, McGinn 1989, Nagel 1994, Warner 1994). One line of reasoning assumes that consciousness is the manifestation of a distinctly nonphysical (...) thing, and hence has no physical properties that might be explored by techniques suitable to physical things. Dualism, as this view is known, is still to be found among those within the tradition of Kant and Hegel, as well as among some with religious convictions. Surprisingly, however, strenuous foot-dragging is evident even among philosophers of a materialist conviction. Indeed, one might say that it is the philosophical fashion of the 90's to pronounce consciousness unexplainable, and to find the explanatory aspirations of neurobiology to be faintly comic if not rather pitiful. The very word, "reductionism" has come to be used more or less synonymously with "benighted-scientism-run-amok", where scientistm apparently means "applying scientific techniques to domains where they are inapplicable." McGinn, perhaps the most unblushing of the naysayers, insists that we cannot expect even to make any headway on the problem. (p. 114) Ironically perhaps, here we are at a conference in honor of Dr. Herbert Jasper who was a great pioneer in moving neuroscience forward on this problem, and where results will be presented allegedly _showing_ additional progress on the problem. Because I am quite optimistic about future scientific progress on the nature of consciousness, my aim here, as a philosopher, is to address the most popular and influential of the skeptical arguments, and to explain why I find them unconvincing. Thus the overall form of the paper is negative, in the sense that I want to show why a set of naysaying arguments fail. (shrink)
In their historical overview of cognitive science, Bechtel, Abraham- son and Graham (1999) describe the field as expanding in focus be- ginning in the mid-1980s. The field had spent the previous 25 years on internalist, high-level GOFAI (“good old fashioned artificial intelli- gence” [Haugeland 1985]), and was finally moving “outwards into the environment and downards into the brain” (Bechtel et al, 1999, p.75). One important force behind the downward movement was Patricia Churchland’s Neurophilosophy (1986). This book began a movement (...) bearing its name, one that truly came of age in 1999 when Kath- leen Akins won a million-dollar fellowship to begin the McDonnell Project in Philosophy and the Neurosciences. The McDonnell Project put neurophilosophy at the forefront of philosophy of mind and cogni- tive science, yielding proliferating articles, conferences, special journal issues and books. In two major new books, neurophilosophers Patricia Churchland (2002) and John Bickle (2003) clearly feel this newfound prominence: Churchland mocks those who do not apply findings in neuroscience to philosophical problems as “no-brainers”; Bickle mocks anyone with traditional philosophical concerns, including “naturalistic philosophers of mind” and other neurophilosophers.

Intersectionality has attracted substantial scholarly attention in the 1990s. Rather than examining gender, race, class, and nation as distinctive social hierarchies, intersectionality examines how they mutually construct one another. I explore how the traditional family ideal functions as a privileged exemplar of intersectionality in the United States. Each of its six dimensions demonstrates specific connections between family as a gendered system of social organization, racial ideas and practices, and constructions of U.S. national identity.
Philosophers have traditionally tried to understand the emotions and their bearing on rationality and moral motivation by assimilating emotion to other categories such as sensation, judgment, and desire. In recent years, moving away from the Cartesian identification of emotions with particular sensations, many philosophers have embraced "judgmentalism," the view that emotions are essentially evaluative judgments or beliefs, with only an accidental connection to the feelings and impulses we intuitively take as "emotional." Anger, for instance, either is or entails the belief (...) that one has been wronged and that the source of injury or offense deserves punishment. (shrink)
This paper attempts to connect recent cross-disciplinary treatments of the cognitive or rational significance of emotions with work in contemporary philosophy identifying an evaluative propositional content of emotions. An emphasis on the perspectival nature of emotional evaluations allows for a notion of emotional rationality that does not seem to be available on alternative accounts.
One of the main challenges in the philosophy of language is determining the form of knowledge of the rules of language. Michael Dummett has put forth the view that knowledge of the rules of language is a kind of implicit knowledge; some philosophers have mistakenly conceived of this type of knowledge as a kind of knowledge-that . In a recent paper in this journal, Patricia Hanna argues against Dummett’s knowledge-that view and proposes instead a knowledge-how view in which knowledge (...) of the rules of language is a kind of practical knowledge, like an agent’s non-propositional knowledge of counting. In this paper I argue, first, that Hanna misunderstands Dummett’s conception of knowledge of linguistic rules, and, second, that Dummett’s considerations of practical knowledge of language pose a problem for Hanna’s knowledge-how view. At the end of the paper, I briefly sketch an account of practical knowledge of language that meets the requirements set by Dummett. (shrink)
We critically review themushrooming literature addressing the neuralmechanisms of moral cognition (NMMC), reachingthe following broad conclusions: (1) researchmainly focuses on three inter-relatedcategories: the moral emotions, moral socialcognition, and abstract moral reasoning. (2)Research varies in terms of whether it deploysecologically valid or experimentallysimplified conceptions of moral cognition. Themore ecologically valid the experimentalregime, the broader the brain areas involved.(3) Much of the research depends on simplifyingassumptions about the domain of moral reasoningthat are motivated by the need to makeexperimental progress. This is a (...) valuablebeginning, but as more is understood about theneural mechanisms of decision-making, morerealistic conceptions will need to replace thesimplified conceptions. (4) The neuralcorrelates of real-life moral cognition areunlikely to consist in anything remotely like a``moral module'' or a ``morality center.'' Moralrepresentations, deliberations and decisionsare probably highly distributed and notconfined to any particular brainsub-system. Discovering the basic neuralprinciples governing planning, judgment anddecision-making will require vastly more basicresearch in neuroscience, but correlatingactivity in certain brain regions withwell-defined psychological conditions helpsguide neural level research. Progress on socialphenomena will also require theoreticalinnovation in understanding the brain'sdistinctly biological form of computationthat is anchored by emotions, needs, drives,and the instinct for survival.

It turned out that there was no phlogiston, no caloric fluid, and no luminiferous ether. Might it turn out that there are no beliefs and desires? Patricia and Paul Churchland say yes} We say no. In part one we give our positive argument for the existence of beliefs and desires.
The category of emotions covers a disputed territory, but clear examples include fear, anger, joy, pride, sadness, disgust, shame, contempt and the like. Such states are commonly thought of as antithetical to reason, disorienting and distorting practical thought. However, there is also a sense in which emotions are factors in practical reasoning, understood broadly as reasoning that issues in action. At the very least emotions can function as "enabling" causes of rational decision-making (despite the many cases in which they are (...) disabling) insofar as they direct attention toward certain objects of thought and away from others. They serve to heighten memory and to limit the set of salient practical options to a manageable set, suitable for "quick-and-dirty" decision-making. (shrink)
Two very different insights motivate characterizing the brain as a computer. One depends on mathematical theory that defines computability in a highly abstract sense. Here the foundational idea is that of a Turing machine. Not an actual machine, the Turing machine is really a conceptual way of making the point that any well-defined function could be executed, step by step, according to simple 'if-you-are-in-state-P-and-have-input-Q-then-do-R' rules, given enough time (maybe infinite time) [see COMPUTATION]. Insofar as the brain is a device whose (...) input and output can be characterized in terms of some mathematical function -- however complicated -- then in that very abstract sense, it can be mimicked by a Turning machine. Given what is known so far brains do seem to depend on cause-effect operations, and hence brains appear to be, in some formal sense, equivalent to a Turing machine [see CHURCH-TURING THESIS]. On its own, however, this reveals nothing at all of how the mind-brain actually works. The second insight depends on looking at the brain as a biological device that processes information from the environment to build complex representations that enable the brain to make predictions and select advantageous behaviors. Where necessary to avoid ambiguity, we will refer to the first notion of computation as algorithmic computation, and the second as information processing computation. (shrink)
