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)

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 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.

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)

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.

Army Officers face increased moral pressure in modern warfare, where character judgement and ethical judgement are vital. This article reports the results of a study of 242 junior British Army officers using the Army Intermediate Concept Measure, comprising a series of professionally oriented moral dilemmas developed for the UK context. Results are suggestive of appropriate application of Army values to the dilemmas and of ethical reasoning aligning with Army excellence. The sample does slightly less well, however, for justification than for (...) action reasoning, and there are differences following initial training for infantry and artillery officers versus other branches of service. Dilemmas involving anti-torture methods and not covering up soldiers' failings generated best results compared to those requiring balance between compassion and mission, and negotiating personal relationships with military needs. Gender differences favouring women were less than those observed for other professional groups using similar measures. This research further develops a much-needed measure of ethical reasoning among junior Army officers, with potential for use among other ranks. This approach is advocated for other professional groups. (shrink)

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

Names, descriptions, and demonstratives raise well-known logical, ontological, and epistemological problems. Perhaps less well known, amongst philosophers at least, are the ways in which some of these problems not only recur with pronouns but also cross-cut further problems exposed by the study in generative linguistics of morpho-syntactic constraints on interpretation. These problems will be my primary concern here, but I want to address them within a general picture of interpretation that is required if wires are not to be crossed. That (...) picture will be sketched in sections 3 and 4; subsequent sections will focus on pronouns and binding, drawing heavily on what has preceded. (shrink)

Mental causes are threatened from two directions: from below, since they would appear to be screened off by lower-order, e.g., neural states; and from within, since they would also appear to be screened off by intrinsic, e.g., syntactical states. A principle needed to parry the first threat -causes should be proportional to their effects- appears to leave us open to the second; for why should unneeded extrinsic detail be any less offensive to proportionality than excess microstructure? I say that the (...) second threat relies on a perversion of proportionality that would lay waste to all causal relations. (shrink)

Despite holding that all concepts are strictly speaking innate, Leibniz attempts to accommodate the common belief that at least some concepts are adventitious by appealing to his theory of ideal action. The essential idea is that an innate concept can be considered adventitious, in a sense, just in case its ideal cause is to be found outside the mind of the one who possesses the concept. I explore this attempt at accommodation and argue that it fails. [See external link for (...) English draft.]. (shrink)

Introduction: Previous findings that inattention and hyperactive/impulsive symptoms predict later peer problems have been mixed. Utilizing two culturally diverse samples with shared methodologies, we assessed the predictive power of dimensionally measured childhood IA and HI symptoms regarding adolescent peer relationships.Methods: A US-based, clinical sample of 228 girls with and without childhood diagnosed attention-deficit/hyperactivity disorder was assessed and followed 5 years later. A Norwegian, population-based sample of 3,467 children was assessed and followed approximately 4 years later. Both investigations used parent and (...) teacher reports of ADHD symptoms and peer relations. Multivariate regression analyses examined the independent contributions of IA and HI symptoms to later peer problems, adjusting for baseline childhood peer problems. We also examined childhood sex as a potential moderator within the Norwegian sample.Results: Higher levels of childhood HI symptoms, but not IA symptoms, independently predicted adolescent peer problems in the all-female clinical sample. Conversely, higher levels of IA symptoms, but not HI symptoms, independently predicted preadolescent peer problems in the mixed-sex population sample. Results did not differ between informants. Associations between ADHD symptom dimensions and peer problems within the Norwegian sample were not moderated by child sex.Discussion: Differential associations between childhood hyperactive/impulsive and inattention symptoms and adolescent peer problems were found across two diverse samples using a shared methodology. Potential explanations for different findings in the clinical vs. population samples include symptom severity as well as age, sex, and cultural factors. We discuss implications for future research, including the importance of dimensional measures of ADHD-related symptoms and the need for shared methodologies across clinical and normative samples.

I examine the (mediated) correspondence between Spinoza and Robert Boyle concerning the latter’s account of fluidity and his experiments on reconstitution of niter in the light of the epistemology and doctrine of method contained in the Treatise on the Emendation of the Intellect. I argue that both the Treatise and the correspondence reveal that for Spinoza, the proper method of science is not experimental, and that he accepted a powerful under-determination thesis. I argue that, in contrast to modern versions, Spinoza’s (...) form of naturalism was a highly rationalist and anti-empirical one. I conclude with a brief account of the value of experience and experimentation for Spinoza’s scientific method. (shrink)

Philosophical Perspectives on Art presents a series of essays devoted to two of the most fundamental topics in the philosophy of art: the distinctive character of artworks and what is involved in understanding them as art. In Part I, Stephen Davies considers a wide range of questions about the nature and definition of art. Can art be defined, and if so, which definitions are the most plausible? Do we make and consume art because there are evolutionary advantages to doing (...) so? Has art completed the mission that guided its earlier historical development, and if so, what is to become of it now? Should architecture be classified as an art form? -/- Part II turns to the interpretation and appreciation of art. What is the target and purpose of the critic's interpretation? Is interpretation primarily directed at uncovering artists' intended meanings? Can apparently contradictory interpretations of a given piece both be true? Are interpretative evaluations entailed by descriptions of a work's aesthetic and artistic characteristics? In addition to providing fresh answers to these and other central questions in aesthetics, Davies considers the nature and content of metaphor, and the relation between the expressive qualities of a work of art and the emotions of its creator.

Although public law scholars have long addressed the problems of accountability generated by private decision-making and "privatization," they have largely ignored this phenomenon in the immigration context. Our ignorance is increasingly indefensible. Millions of employers - private parties - are required by law to screen their workers for unauthorized immigrants, and growing evidence suggests that they use their screening power to ignore workplace protections and to otherwise exploit these workers. This article is the first attempt to apply the insights generated (...) by the privatization literature to immigration law. It argues that our nation's employers have emerged as private immigration screeners who, like airport inspectors screening for ineligible entrants and law enforcement officers screening for criminal noncitizens, assist the Department of Homeland Security in identifying unauthorized workers for removal. More than just agents of exploitation, reframing employers as private screeners demonstrates that they are also agents of the state. Borrowing analytical concepts developing in the privatization literature, I argue that the high risk of abuse and the lack of readily available mechanisms for reducing that risk raise troubling implications over the kind of power that employers wield as private immigration screeners in the workplace. Reframing our nation's employers as private screeners gives theoretical coherence to the discretionary decision-making authority they actually wield, and explains why they have used that authority to exploit workers - as private parties carrying out public duties, they are incentivized to serve their own interests instead of verifying the immigration status of their workers in good faith. Examining the problem of private immigration screening also forces us to reconsider two aspects about immigration screening generally. First, although immigration law tends to reward unauthorized immigrants who lay low and tends to punish those who draw attention to themselves, I suggest that we ought to rethink this logic at least in the context of the workplace. Because workplace violations committed by employers are typically enforced by private parties, punishing unauthorized immigrants who attempt to assert these rights and thus draw attention to themselves, only encourages workplace violations by employers and fosters a culture of lawlessness. Second, thinking about how decision-making authority within immigration law should be allocated between the public and the private contributes to the current conversation over how similar decision-making authority should be allocated between federal entities and local entities. Although questions of accountability have lingered in the backdrop of the immigration federalism debate, I suggest that scholars would be well served to foreground these questions and answer them head-on.

In what follows I propose to bring out certain methodological properties of projects of modelling the tacit realm that bear on the kinds of modelling done in connection with scientific cognition by computer as well as by ethnomethodological sociologists, both of whom must make some claims about the tacit in the course of their efforts to model cognition. The same issues, I will suggest, bear on the project of a cognitive psychology of science as well.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.4 (2003) 369-372 [Access article in PDF] Unity of Agency and Volition:Some Personal Reflections Stephen Weiner The issues of unity of agency, self-as-narrative, and more generally, volition are highly personal to me. Indeed, I would say I have frequently been obsessed with them. I am 52 years old, and date the onset of my psychiatric symptoms—my long-term misery—very specifically: 11:00 pm Pacific Standard Time, (...) August 28, 1965. At almost precisely that time, I started obsessing that I was homosexual and, in fact, turning into a girl. Within days, derealization followed: for instance, the houses in my neighborhood seemed one-dimensional—they seemed as though they were painted, as though I could stick my hand or an object through them. Colors seemed less bright as well—but I hardly had words for all this at the time: it was an overwhelmingly preverbal feeling, but I found some words for it.I was also depressed, and knew I was depressed—that is, I was worried, had trouble sleeping, and had suicidal thoughts and feelings. Within weeks, I asked my parents if I could see a psychiatrist, and I did. I remember asking my psychiatrist if he ever thought about the possibility that everything might be an illusion, and he quoted the refrain from "Row, Row, Row Your Boat": "merrily, merrily, merrily, merrily, life is but a dream." But just asking him produced a chilling feeling that he did not exist and, largely for this reason, I did not mention unreality feelings again to therapists for another 20 years.So, like Dr. Wells' patient Edward, described by James Phillips (2003), I was in trouble; like Edward, I was starting to construct a narrative. I started feeling that I had "to tell my story" at about this time—before then, I had not felt a need to do that. That may be partly because young children take life for granted (at least, I did), and it may be partly because suffering, by its very nature, demands explanation; both reasons were probably operating—certainly, both my parents told me years later that I had seemed emotionally distressed as a child, and my mother told they would have given me Ritalin if it had been available. So, to other people (my parents and my teachers) I was mentally ill in some sense, and I have some pretty clear memories of what I now recognize as depression, especially in the second and third grades; but I did not think of myself as sick and I did not think of myself as suffering—and I did not experience the duality (at least) of selves that I started to experience almost immediately in August 1965.Phillips further points out that the "future Edward" could look back in his narrative, at a later age, and reconstruct his history either as someone with a continuing mental illness, or as someone who had attained a secure, healthy adulthood and saw his experience as adolescent pain in the service of ultimate adult health and integration. I see my story, I am sorry to report, as [End Page 369] one of unremitting basic pain but with the positive dimension that I was able to go on, obtain a good education, work a good deal in my adult life, and father a child. But my narrative—and am I not, as a highly verbal person, almost constrained to think of my life as a narrative?—has been one, as Phillips (following Kleinman) realizes, of suffering. It is, above all else, an illness narrative. I find the approach of J. Melvin Woody (2003)—of privileging performing and performing arts and spatial metaphors over story—less relevant and true to myself, although I see no reason to argue with Mary's preference for such forms. It may be that the temporal discontinuities she has experienced predispose her to see herself in such terms—may, in fact, necessitate doing so. I am not exactly sure why, but it probably has to do with acting, with trying on and performing one role... (shrink)

I. The Conscious Mind is a hugely likable book. Perceptive, candid, and instructive page by page, the work as a whole sets out a large and uplifting vision with cheeringly un-Dover-Beach-ish implications for “our place in the universe.” A book that you can’t helping wanting to believe as much as you can’t help wanting to believe this one doesn’t come along every day. It is with real regret that I proceed to the story of why belief would not come.
