Christine Korsgaard claims that an agent is less than fully rational if she allows some attitude to inform her deliberation even though she cannot justify doing so. I argue that there is a middle way, which Korsgaard misses, between the claim that our attitudes neither need nor admit of rational assessment, on the one hand, and Korsgaard's claim that the attitudes which inform our deliberation always require justification, on the other: an agent needs reasons to opt out of her concerns (...) – not reasons to opt into them or to stay in. As long as an agent has no good reason to abandon some concern of hers, she is reasonable to harbour it, and to allow it to inform her view of what reasons she has. A rational agent must therefore have the capacity to form higher-order attitudes toward her concerns; but rationality only requires that she exercise that capacity when she has some good reason to do so.

John McDowell argues that for virtuous agents the requirements of virtue do not outweigh competing considerations, but 'silence' them. He explains this claim in two different ways: a virtuous agent (a) will not be tempted to act in a way which is incompatible with virtue ('motivational silencing'), or (b) will not believe that he has any reason to act in a way which is incompatible with virtue ('rational silencing'). I identify a small class of cases in which alone McDowell's claims (...) about rational silencing are true. He draws his claims from Aristotle's assertion that a life of virtue is 'self-sufficient'. I offer an alternative reading of Aristotle's assertion, which does not imply the truth of McDowell's. But McDowell's claims about motivational silencing are true. (shrink)

What is it to "value" something, in the semi-technical sense of the term that Gary Watson establishes? I argue that valuing something consists in caring about it. Caring involves not only emotional dispositions of the sort that Agnieszka Jaworska has elaborated, but also a distinctive cognitive disposition – namely, a (defeasible) disposition to believe the object cared about to be a source of agent-relative reasons for action and for emotion. Understood in this way, an agent's carings have a stronger claim (...) to "speak for" her as her values than do other attitudes that have been proposed for this role. In particular, an agent's carings establish more robust psychological continuities and cross-temporal connections than do self-governing policies of the sort that Michael Bratman has described; and they forge diachronic coherence not just in her deliberation and action, as self-governing policies do, but also in her cognitive and emotional life. An agent's carings thus help to constitute her identity as a temporally persisting subject . Self-governing policies are at best ersatz -values, which an agent may choose to adopt when she finds that her proper values – her cares – leave her course underdetermined. (shrink)

When a reasonable agent deliberates about what to do, she entertains only a limited range of possible courses of action. A theory of practical reasoning must therefore include an account of deliberative attention: an account that both explains the patterns of deliberative attention that reasonable agents typically display and allows us to see why these patterns of deliberative attention are reasonable. I offer such an account, built around two, central claims. A reasonable agent who cares about some end is disposed (...) to exclude courses of action which she believes to be incompatible with that end from the range of possibilities that she will entertain as options in practical deliberation. As I shall put it, an agent’s cares establish deliberative boundaries for her practical thought. The stability of a deliberative boundary varies with the depth of the care that explains it. These two claims motivate the Boundary-Driven Model of the path that a reasonable agent’s deliberative attention will take in temporally extended deliberation. If we locate the model within a maximizing conception of practical rationality, then boundary-driven deliberation, of the sort that the model describes, can be understood and justified instrumentally, as a heuristic device. But if we suppose that there is no single index of value that successful practical choice maximizes, then boundary-driven deliberation is partly constitutive of reasonableness in practical thought. It allows an agent facing plural and incommensurable values to frame her deliberative problems narrowly enough that, in conjunction with deliberative devices which are not part of the model but which are compatible with it, she may be able to reach a non-arbitrary decision – and so give a determinate, verdictive sense to the phrase “the best course of action available to me” in cases in which a determinate meaning for this phrase would otherwise be lacking.

This essay seeks to explain a morally important class of psychological incapacity—the class of what Bernard Williams has called “incapacities of character.” I argue for two main claims: (1) Caring is the underlying psychological disposition that gives rise to incapacities of character. (2) In competent, rational adults, caring is, in part, a cognitive and deliberative disposition. Caring is a mental state which disposes an agent to believe certain considerations to be good reasons for deliberation and action. And caring is a (...) mental state which structures an agent’s practical deliberation, by establishing presumptive boundaries on the landscape of possibilities over which her deliberative imagination ranges. Incapacities of character are a consequence of the structure which these presumptive boundaries give to an agent’s deliberation. (shrink)

I elucidate a frame of mind that David Wiggins callsrespect for nature, which he understands as a special attitude toward asui generisobject, Natureas such. A person with this frame of mind takes nature to impose defeasible limits on her action, so that there are some courses of action that she will refuse even to entertain, except in circumstances of dire exigency. I defend the reasonableness of respect for nature, drawing upon considerations in Wiggins's work. But I argue that the natural (...) systems that comprise the proper object of respect for nature are notsui generis; they are kindred, for practical reason, to complex social, political, and economic systems that we inhabit. I argue that it is reasonable to treat all such valuable systems with a similar respect, and that this respect is continuous with the respect we owe to persons and to valuable objects more generally. In all of these cases, respect consists, in part, in a disposition to defeasible constraints on practical deliberation. (shrink)

This new selection of Thoreau’s essays traces his trajectory as a writer for the outlets of his day—the periodical press, newspapers, and compendiums—and as a frequent presenter on the local lecture circuit. By arranging the writings chronologically, the volume re-creates the experience of Thoreau’s readers as they followed his developing ideas over time. Jeffrey S. Cramer, award-winning editor of six previous volumes of works by Thoreau, offers the most accurate text available for each essay and provides convenient on-page annotations. (...) He establishes context and guides the reader through unfamiliar allusions and references, plumbing the depths of Thoreau’s writings with unprecedented insight. Among the essays in this book: · The Last Days of John Brown · Resistance to Civil Government [Civil Disobedience] · Thomas Carlyle and His Works · Natural History of Massachusetts · and many more.

Through an analysis of philosophical temperaments, I argue that both William James and Michel Foucault believed the central task of philosophy not only to be the generation of new ideas or ways of thinking, but also to create new temperaments, new ways of inhabiting the world. Though James and Foucault in many ways agree on the ends of philosophy, the methods and strategies that they developed differ according to the problems with which each philosopher was concerned. Although James gives a (...) rich account of what it means to see philosophy as the reconstruction of temperament, Foucault’s genealogical method explains concretely how temperaments might be reconstructed through the use of history. Raising questions of how this work might effectively continue today, I argue that Foucauldians and Jamesians, Continental philosophers and American pragmatists, might find common cause in exploring the production and reconstruction of democratic temperaments in response to social problems.

The change in shape of the C. elegans embryo from an ovoid ball of cells into a worm-shaped larva is driven by three events within the cells of the hypodermis (epidermis): (1) intercalation of two rows of dorsal cells, (2) enclosure of the ventral surface by hypodermis, and (3) elongation of the embryo. While the behavior of the hypodermal cells involved in each of these processes differs dramatically, it is clear that F-actin and microtubules have essential functions in each of (...) these processes, whereas contraction of actomyosin structures appears to be involved specifically in elongation. Molecular analysis of these processes is revealing components specific to C. elegans as well as components found in other systems. Since C. elegans hypodermal cells demonstrate dramatically different behaviors during intercalation, enclosure and elongation, the study of cytoskeletal dynamics in these processes may reveal both unique and conserved activities during distinct epithelial morphogenetic movements.

The ontological question of what there is, from the perspective of common sense, is intricately bound to what can be perceived. The above observation, when combined with the fact that nouns within language can be divided between nouns that admit counting, such as ‘pen’ or ‘human’, and those that do not, such as ‘water’ or ‘gold’, provides the starting point for the following investigation into the foundations of our linguistic and conceptual phenomena. The purpose of this paper is to claim (...) that such phenomena are facilitated by, on the one hand, an intricate cognitive capacity, and on the other by the complex environment within which we live. We are, in a sense, cognitively equipped to perceive discrete instances of matter such as bodies of water. This equipment is related to, but also differs from, that devoted to the perception of objects such as this computer. Behind this difference in cognitive equipment underlies a rich ontology, the beginnings of which lies in the distinction between matter and objects. The following paper is an attempt to make explicit the relationship between matter and objects and also provide a window to our cognition of such entities. (shrink)

This case study details a request from a patient family member who calls our service without an articulated ethical dilemma. The issue that arose involved the conflict between continuing further medical interventions versus transitioning to supportive or palliative care and transferring the patient home. Beyond the resolution of the ethical dilemma, this narrative illustrates an approach to ethics consultation that seeks practical resolution of ethical dilemmas in alignment with patient goals and values. Importantly, the family’s suffering is addressed through a (...) relationship driven, humanistic approach that incorporates elements of compassion, empathy and dialog. (shrink)

The cerebellum has been hypothesized to play a role in a variety of movement timing tasks that involve the processing of temporal information on a variety of timescales. Braitenberg, Heck & Sultan propose a new theory of cerebellar function that is able to account for movement timing on the order of a couple of hundred milliseconds. However, this theory does not account for the rôle the cerebellum plays in the acquisition and retention of adaptively timed discrete movements that are on (...) the order of 200 to 1000 milliseconds, and therefore does not account for the entire temporal range of cerebellar dependent processing.

As spin is a fundamental feature of the universe, preliminary evidence suggests that its study could help in understanding consciousness. Research detailed in this article further develops the author's work in Keen (2005). The findings demonstrate that rotating objects generate fields that are also associated with mind-generated fields. Numerous quantitative properties of these fields generated by rotation are shown to be very different to fields associated with static objects. Dipole antenna radiation patterns are also discovered. The conclusions suggest that vorticity (...) is not only involved in consciousness, but also has wider implications in understanding our universe, and therefore the subject warrants further research.

This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect (...) from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.

Levelt et al. describe a model of speech production in which lemma access is achieved via input from nondecompositional conceptual representations. They claim that existing decompositional theories are unable to account for lexical retrieval because of the so-called hyperonym problem. However, existing decompositional models have solved a formally equivalent problem.

According to Pylyshyn, the early visual system is able to categorize perceptual inputs into shape classes based on visual similarity criteria; it is also suggested that written words may be categorized within early vision. This speculation is contradicted by the fact that visually unrelated exemplars of a given letter (e.g., a/A) or word (e.g., read/READ) map onto common visual categories.

Using a combination of reviewing the extensive relevant literature, the author's original scientific research, and exploring the boundaries of human experiences, this article develops a model for consciousness. As a consequence, consciousness is elevated in the scientific understanding of the structure of the Universe, possibly enabling easier interpretation of such concepts as the anthropic principle and quantum physics. The handling of information is a key, leading to a review of the Information Field theory, together with a preliminary attempt at striking (...) the appropriate balance between mind and matter.

The lattice of r.e. equivalence relations has not been carefully examined even though r.e. equivalence relations have proved useful in logic. A maximal r.e. equivalence relation has the expected lattice theoretic definition. It is proved that, in every pair of r.e. nonrecursive Turing degrees, there exist maximal r.e. equivalence relations which intersect trivially. This is, so far, unique among r.e. submodel lattices.

Understanding a patient’s story is integral to providing ethically supportable and practical recommendations that can improve patient care. Important skills include how to elicit an individual’s story, how to weave different narrative threads together, and how to assist the care team, patients, and caregivers to resolve difficult decisions or moral dilemmas. Narrative approaches to ethics consultation deepen dialogue and stakeholders’ engagement to reveal important values, preferences, and beliefs that may prove critical in resolving care challenges. Recognizing barriers to narrative inquiry, (...) such as patients who are unable or refuse to share their story, is also important. In this article we offer specific steps and guidelines that ethicists can follow to systematically elicit and construct patients’ stories. We provide a case example to illustrate how a narrative approach to ethics consultation illuminates salient ethical issues that may otherwise go unnoticed. We argue that this approach should be part of every consultant’s tool kit. (shrink)

The formal beginning of comedy is firmly dated to the Dionysia of 486 B.C.E.1 For what preceded it there were at least three ancient candidates: phallic processions, Doric comedy and Susarion. Each is supported by visual evidence of the sixth century B.C.E., each explains certain features of Old Comedy, but all have some anomalies as well. Striking is how many forms of performance attested in the sixth century contained comic elements. All these other forms ceased with the introduction of comedies (...) to the Dionysia in 486 B.C.E., which coincides with the ascendancy of the demos; yet it was not until forty years later that comedy becomes unabashedly political.
