Background Medical Assistance in Dying in Canada came into effect in 2016 with the passing of Bill C-14. As patient interest and requests for MAID continue to evolve in Canada, it is important to understand the attitudes of future providers and the factors that may influence their participation. Attitudes towards physician hastened death in general and the specific provision of MAID are unknown among Canadian residents. This study examined residents’ attitudes towards PHD and MAID, and identified factors that may influence (...) their decision to participate in PHD and provide MAID. Methods A cross-sectional survey was adapted from prior established surveys on MAID to reflect the Canadian setting. All Canadian family medicine programs were invited to participate. The survey was distributed between December 2016 and April 2017. Analysis of the results included descriptive statistics to characterize the survey participants and multivariable logistic regressions to identify factors that may influence residents’ attitudes towards PHD and MAID. Results Overall, 247 residents from 6 family medicine training programs in Canada participated. While residents were most willing to participate in treatment withdrawal, active participation in PHD and MAID by prescription of a lethal drug and lethal injection were less acceptable. Logistic regressions identified religion as a consistent and significant factor impacting residents’ willingness to participate in PHD and MAID. Residents who were not strictly practicing a religion were more likely to be willing to participate in PHD and MAID. Increased clinical exposure to death and dying crudely correlated with increased willingness to participate in PHD and MAID, but when examined in multivariable models, only a few activities had a statistically significant association. Other significant factors included the residents’ sex and location of training. Conclusions Residents are hesitant to provide MAID themselves, with religious faith being a major factor impacting their decision. (shrink)

Human motor learning is governed by a suite of interacting mechanisms each one of which modifies behavior in distinct ways and rely on different neural circuits. In recent years, much attention has been given to one type of motor learning, called motor adaptation. Here, the field has generally focused on the interactions of three mechanisms: sensory prediction error SPE-driven, explicit, and reinforcement learning. Studies of these mechanisms have largely treated them as modular, aiming to model how the outputs of each (...) are combined in the production of overt behavior. However, when examined closely the results of some studies also suggest the existence of additional interactions between the sub-components of each learning mechanism. In this perspective, we propose that these sub-component interactions represent a critical means through which different motor learning mechanisms are combined to produce movement; understanding such interactions is critical to advancing our knowledge of how humans learn new behaviors. We review current literature studying interactions between SPE-driven, explicit, and reinforcement mechanisms of motor learning. We then present evidence of sub-component interactions between SPE-driven and reinforcement learning as well as between SPE-driven and explicit learning from studies of people with cerebellar degeneration. Finally, we discuss the implications of interactions between learning mechanism sub-components for future research in human motor learning. (shrink)

Task-unrelated thought (TUT) occurs frequently in our daily lives and across a range of tasks, but we know little about how this phenomenon arises during and influences the way we communicate. Conversations also provide a novel opportunity to assess the alignment (or divergence) in TUT during dyadic interactions. We conducted a study to determine: (a) the frequency of TUT during conversation as well as how partners align/diverge in their rates of TUT, (b) the subjective and behavioral correlates of TUT and (...) TUT divergence during conversation, and (c) if perceived social group identity impacts TUT and TUT divergence during conversation. We used a minimal groups induction procedure to assign participants (N = 126) to either an ingroup, outgroup, or control condition. We then asked them to converse with one another via a computer-mediated text chat application for 10 min while self-reporting TUTs. On average, participants reported TUT about once every 2 min; however, this rate was lower for participants in the ingroup condition, compared to the control condition. Conversational pairs in the ingroup condition were also aligned more in their rates of TUT compared to the outgroup condition. Finally, we discuss subjective and behavioral correlates of TUT and TUT divergence in conversations, such as valence, turn-taking ratios, and topic shifts. (shrink)

Resumo A problemática na relação entre Filosofia e Cinema dá origem a duas questões: a primeira, sobre as condições que os filmes têm de satisfazer a fim de poderem ser devidamente tratados por uma compreensão filosófica; a segunda, sobre os requisitos, que os discursos sobre os filmes têm de satisfazer, em ordem a serem legitimamente considerados como filosóficos. Respondendo à primeira pergunta, através de uma análise ao debate entre Paisley Livingston e Aaron Smuts, acerca da “Filosofia do Cinema”, será (...) afirmado que, embora os filmes em si mesmos não façam filosofia, é possível fazer filosofia a partir deles, desde que estes expressem ideias estéticas. Respondendo à segunda questão, através da leitura crítica de Days of Being Wild, In the Mood of Love e 2046 de Wong Kar-wai, com referência aos conceitos de Kierkegaard, Girard e Deleuze, será argumentado que uma análise filosófica implica a renovação de conceitos filosóficos centrais e o alargamento da compreensão da natureza das imagens cinematográficas. Palavras-chave : Deleuze, emoção-imagem, filosofia do cinema, Kierkegaard, repetição, Wong Kar-waiThe problem of the relationships between Philosophy and Films raises two questions: first, the conditions that films have to fulfill in order to be rightly concerned by a philosophical understanding; second the requirements that discourses about films have to fulfill in order to be truly considered as philosophical ones. Answering to the first question through a survey of the debate between Paisley Livingston and Aaron Smuts about “Film-Philosophy”, I will affirm that, though films in themselves are not doing philosophy, it is possible to do philosophy out of them provided they express aesthetical ideas. Answering to the second question through a critical reading of Wong Kar-wai’s Days of Being Wild, In the Mood for Love, and 2046 referring to the concepts of Kierkegaard, Girard and Deleuze, I will argue that a philosophical analysis implies to renew core philosophical concepts and to extend our understanding of the nature of cinematographic images.

Fighting ability, although recognized as fundamental to intrasexual competition in many nonhuman species, has received little attention as an explanatory variable in the social sciences. Multiple lines of evidence from archaeology, criminology, anthropology, physiology, and psychology suggest that fighting ability was a crucial aspect of intrasexual competition for ancestral human males, and this has contributed to the evolution of numerous physical and psychological sex differences. Because fighting ability was relevant to many domains of interaction, male psychology should have evolved such (...) that a man’s attitudes and behavioral responses are calibrated according to his formidability. Data are reviewed showing that better fighters feel entitled to better outcomes, set lower thresholds for anger/aggression, have self-favoring political attitudes, and believe more in the utility of warfare. New data are presented showing that among Hollywood actors, those selected for their physical strength (i.e., action stars) are more likely to believe in the utility of warfare. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 8.4 (2001) 317-322 [Access article in PDF] On Wolfgang Blankenburg, Common Sense, and Schizophrenia Aaron L. Mishara Introduction In its increasing openness to neuroscience (Cowan, Harter, and Kandel 2000) and other of its neighboring disciplines, mainstream biological psychiatry has allowed psychopathology, philosophy, and philosophical approaches to psychopathology to play an increased role in current research interests. Given this new openness, and the acknowledgment of (...) the severity of one of psychiatry's most debilitating, costly, and intractable disorders, 1 the translation of W. Blankenburg's 1969 article concerning the psychopathology of common sense does not merely serve historical interest. It is an exceptional example of a not well-known trend in German- and French-speaking psychiatry to apply philosophical phenomenology and existentialism to psychopathological research. This trend, which reached a peak in the late 1950s and was strong well into the 1970s, has dwindling, but nevertheless, current representatives in Heidelberg and Zurich and is scattered in a few other places in Europe, Japan, the United States, and South America. The view of the Zeitgeist—which may sound astonishing, even antiquated to contemporary readers—was highly ambitious: Conceptual approaches, such as philosophical ("transcendental") phenomenology, were expected to supply knowledge about the structure of consciousness and its disturbance in various mental disorders.Following the lead of Binswanger and Szilasi, who viewed schizophrenia as an "experiment of nature" that enables us to view underlying processes otherwise hidden to "natural, everyday consciousness," Blankenburg believed that it may be possible to map the formal properties of the psychopathology of schizophrenia—precisely in the loss of common sense—as a disturbance to the basic organization of conscious experience. Any attempt to summarize this rather abstract and complex approach in a brief commentary would be ill advised. In passing, rather, I will remark that such efforts could have profound relevance to the current research of schizophrenia and its underlying neurobiology. This research has gradually acknowledged the importance of taking the patient's subjective experience of the disorder into account (Mishara, Parnas, and Naudin 1998). In this commentary, I will first give an account of the biographical and clinical reasons that led Blankenburg to turn to the problem of common sense and its relevance for schizophrenia. I will then explore what implications [End Page 317] his work may have for more recent findings concerning schizophrenia. Blankenburg's Intellectual Development Born in 1928, W. Blankenburg, the son of a Lufthansa pilot who pioneered transatlantic commercial flights, began his studies in Freiburg im Breisgau in 1947. While at Freiburg, Blankenburg heard lectures in philosophy given by E. Fink (the former assistant to Husserl) and Max Mueller, and in psychology, by R. Heiss and others. After three years, Blankenburg turned to the study of medicine, producing a dissertation in 1956 on an application of Daseinsanalysis (Heidegger and Binswanger) to a case of paranoid schizophrenia. Binswanger wrote the forward to the publication. Between 1956 and 1958, Blankenburg studied internal medicine in Heidelberg with the accomplished phenomenologist of bodily experience (Leibphaenomenologer) and student of V. von Weizsaecker Herbert Pluegge. He spent one semester in Goettingen where he attended lectures by the ontological philosopher Nicolai Hartmann, who provided for Blankenburg a more useful approach to the problem of nature and natural science than Heidegger's primary emphasis on the question of Being. During his Freiburg years, Blankenburg attended small seminars led by Heidegger in the Schwarzwald forest. (Heidegger had been forbidden to teach after the end of World War II.) Blankenburg recalls that the participants would sit on logs in an open field as if to invoke Heidegger's concept of the clearing (Lichtung) of Being. While not entirely sympathetic with Heidegger's philosophy, Blankenburg learned to carefully "listen"—as Heidegger would repeatedly emphasize—to language, not merely poetic or philosophical language, but the language of the patients he would meet in clinical practice.During this time, Blankenburg heard lectures by W. Szilasi, the philosopher-scientist who held Husserl's and Heidegger's chair in the department of philosophy. Szilasi collaborated with the phenomenological psychiatrist, L. Binswanger. Their effort to apply concepts from Husserl's... (shrink)

This paper is about how to give human-like powers to complete agents. For this the most important design choice concerns the overall architecture. Questions regarding detailed mechanisms, forms of representations, inference capabilities, knowledge etc. are best addressed in the context of a global architecture in which different design decisions need to be linked. Such a design would assemble various kinds of functionality into a complete coherent working system, in which there are many concurrent, partly independent, partly mutually supportive, partly potentially (...) incompatible processes, addressing a multitude of issues on different time scales, including asynchronous, concurrent, motive generators. Designing human like agents is part of the more general problem of understanding design space, niche space and their interrelations, for, in the abstract, there is no one optimal design, as biological diversity on earth shows.

The idea that intentions make the difference between voluntary and non-voluntary behaviors is simple and intuitive. At the same time, we lack an understanding of how voluntary actions actually come about, and the unquestioned appeal to intentions as discrete causes of actions offers little if anything in the way of an answer. We cite evidence suggesting that the origin of actions varies depending on context and effector, and argue that actions emerge from a causal web in the brain, rather than (...) a central origin of intentional action. We argue that this causal web need not be confined to the central nervous system, and that proprioceptive feedback might play a counterintuitive role in the decision process. Finally we argue that the complex and dynamic origins of voluntary action and their interplay with the brain’s propensity to predict the immediate future are better studied using a dynamical systems approach.

In their target article, McKay & Dennett (M&D) conclude that only “positive illusions” are adaptive misbeliefs. Relying on overly strict conceptual schisms (deficit vs. motivational, functional vs. organic, perception vs. belief), they prematurely discount delusions asbiologicallyadaptive. In contrast to their view that “motivation” plays a psychological but not a biological function in a two-factor model of the forming and maintenance of delusions, we propose asingleimpairment in prediction-error–driven (i.e., motivational) learning in three stages in which delusions play a biologically adaptive role.

Readers of Spinoza's philosophy have often been daunted, and sometimes been enchanted, by the geometrical method which he employs in his philosophical masterpiece the Ethics. In Meaning in Spinoza's Method Aaron Garrett examines this method and suggests that its purpose, in Spinoza's view, was not just to present claims and propositions but also in some sense to change the readers and allow them to look at themselves and the world in a different way. His discussion draws not only on (...) Spinoza's works but also on those of the philosophers who influenced Spinoza most strongly, including Hobbes, Descartes, Maimonides and Gersonides. This controversial book will be of interest to historians of philosophy and to anyone interested in the relation between form and content in philosophical works. (shrink)

What is the relation between intelligence and computation? Although the difficulty of defining `intelligence' is widely recognized, many are unaware that it is hard to give a satisfactory definition of `computational' if computation is supposed to provide a non-circular explanation for intelligent abilities. The only well-defined notion of `computation' is what can be generated by a Turing machine or a formally equivalent mechanism. This is not adequate for the key role in explaining the nature of mental processes, because it is (...) too general, as many computations involve nothing mental, nor even processes: they are simply abstract structures. We need to combine the notion of `computation' with that of `machine'. This may still be too restrictive, if some non-computational mechanisms prove to be useful for intelligence. We need a theory-based taxonomy of {\em architectures} and {\em mechanisms} and corresponding process types. Computational machines my turn out to be a sub-class of the machines available for implementing intelligent agents. The more general analysis starts with the notion of a system with independently variable, causally interacting sub-states that have different causal roles, including both `belief-like' and `desire-like' sub-states, and many others. There are many significantly different such architectures. For certain architectures (including simple computers), some sub-states have a semantic interpretation for the system. The relevant concept of semantics is defined partly in terms of a kind of Tarski-like structural correspondence (not to be confused with isomorphism). This always leaves some semantic indeterminacy, which can be reduced by causal loops involving the environment. But the causal links are complex, can share causal pathways, and always leave mental states to some extent semantically indeterminate. (shrink)

Proponents of political liberalism standardly assume that the citizens of an ideal liberal society would be overwhelmingly reasonable. I argue that this assumption violates political liberalism's own constraints of realism—constraints that are necessary to frame the central problem that political liberalism aims to solve, that is, the problem of reasonable pluralism. To be consistent with these constraints, political liberalism must recognize that, as with reasonable pluralism, widespread support for unreasonable moral and political views is an inevitable feature of any liberal (...) society. I call this the fact of unreasonable pluralism. This fact threatens Rawlsian political liberalism's account of stability because an overlapping consensus cannot stably order a society pervaded by unreasonable views. My argument also raises questions about the coherence of Rawls's conception of ideal theory. (shrink)

After outlining an enactive account of fact perception, I consider J. L. Austin's discussion of the argument from illusion. From it I draw the conclusion that when fact perception is primary the objects perceived are those involved in the fact. A consideration of Adelson's checkershadow illusion shows that properties as basic as luminance are perceived in the contexts of facts as well. I thus conclude that when facts are perceived they structure our perception of objects and properties. I then argue (...) that which facts are perceived is determined by contexts which are themselves determined by our interests. Here I appeal to Heidegger's views on everyday coping as a foundational form of intentional directedness. A discussion of Simons and Chabris? gorilla experiment provides contemporary empirical support of the Heideggerian analysis. Finally, I argue that there cannot be context-free perception on the enactive account inasmuch as perception, qua action, is always permeated with the interests of the subject. (shrink)

The work of Hussefl and Freud had common sources in the philosophy, psychology and physiology of the nineteenth century. Herbart, Brentano, Helmholtz, Fechner, Wundt and Mach were among the towering figures in their common background who had influence on their respective work. 1 Although contemporaries who had little concern for the other's professional interest, Husserl and Freud nevertheless struggled with some common problems. One of these is the relationship of sensation to memory and to the experience of time. The concepts (...) of sensation, memory and time were, in fact, artifacts which the empirical methods of nerve-physiology, the psychophysical testing of sensory thresholds, as well as the metaphysics and positivism of the late nineteenth century had left them.

This article argues against the no-self or nonegological account of bodily self-awareness. It proposes an account of consciousness that challenges Miri Albahari's forceful defence of a nonegological view of consciousness, particularly its sharp distinction between subject and self. It contends that the subject of experience is a bodily subject and not merely an embodied one and argues that in order to be a subject of experience even in the minimal sense of witnessing-from-a-perspective, one must be prereflectively aware of oneself as (...) a living body. It also argues in defence of the necessary presence of a minimal bodily sense of self as a constitutive feature of perspectival awareness of the world. (shrink)

Recent advances in the field of statistical learning have established that learners are able to track regularities of multimodal stimuli, yet it is unknown whether the statistical computations are performed on integrated representations or on separate, unimodal representations. In the present study, we investigated the ability of adults to integrate audio and visual input during statistical learning. We presented learners with a speech stream synchronized with a video of a speaker’s face. In the critical condition, the visual (e.g. /gi/) and (...) auditory (e.g. /mi/) signals were occasionally incongruent, which we predicted would produce the McGurk illusion, resulting in the perception of an audiovisual syllable (e.g. /ni/). In this way, we used the McGurk illusion to manipulate the underlying statistical structure of the speech streams, such that perception of these illusory syllables facilitated participants’ ability to segment the speech stream. Our results therefore demonstrate that participants can integrate audio and visual input to perceive the McGurk illusion during statistical learning. We interpret our findings as support for modality-interactive accounts of statistical learning. (shrink)

ABSTRACT Much has been made of the apparent tensions in Nietzsche's ethical and metaethical views. In this essay I examine a kind of value standard available to Nietzsche that is present in his work. I offer an interpretation of honesty as both a Nietzschean virtue and a means of ethical assessment. Despite Nietzsche's well-known criticisms of truth, he upholds honesty as the only remaining virtue of his free spirits. Honesty has been treated in the literature primarily in the contexts of (...) truth or life affirmation, but I argue that we should instead recognize honesty as a virtue within the context of valuing. I defend honesty as a distinct kind of truthfulness and sincerity involving what I call confrontation. The seeds of Nietzsche's mature view are first evident in his work on tragedy, then developed further in Zarathustra, ultimately revealing a constraint on valuing that is essential to Nietzsche's broader normative projects.

In both environmental ethics and bioethics, one central issue is the range of entities that are morally considerable. According to one view on this issue, we ought to extend consideration to any entity that possesses interests. But what kinds of entities possess interests? Some philosophers have argued that only sentient beings can have interests, while others have held that all living organisms possess interests in the fulfillment of their biological functions. Is it true that all living organisms have biological interests? (...) The standard arguments made against biological interests are unsatisfactory. There are two central reasons why we ought to reject the idea of biological interests: a metaphysical reason and a normative reason. First, the idea of biological interests implies a metaphysically mysterious account of the nature of how things come to have value for an entity. Second, as normative interests, the idea of biological interests implies that what is good for human beings is at least partly determined by things that are external to themselves, completely independent of their capacities for desires, conflicting with the individual ideal of self-direction, according to which it is fundamentally desirable that how we ought to live (or what is good for one) is grounded in one’s own capacities for desires. It is still an open possibility that nonsentient entities may be morally considerable in the sense of having intrinsic value. (shrink)

This paper offers an account of Nietzsche's re-evaluation of values that seeks to satisfy two desiderata, both important if Nietzsche's project is to stand a chance of success. The first is that Nietzsche's re-evaluations must be capable of being understood as authoritative by those whose values are subject to re-evaluation. The second is that Nietzsche's project must not falsify the values being re-evaluated, by, for example, misrepresenting intrinsic values as instrumental values. Given this, five possible forms of re-evaluation are distinguished, (...) and, of these, four are argued both to satisfy the specified desiderata and to feature more or less prominently in Nietzsche's later work. The conclusion of the paper is therefore that Nietzsche's project has at least the right general shape to succeed, and that the reasons for this depend upon acknowledging the importance of the desiderata and of the distinctions to which the paper draws attention.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXVI, Number 1, April 2000, pp. 171-177 Hume's Revised Racism Revisited AARON GARRETT John Immerwahr's brief note "Hume's Revised Racism" is doubtless one of the most intriguing recent discussions of Hume and racism.1 Immerwahr presents a thesis as to why Hume revised a footnote originally added to his essay "Of National Characters" (hereafter "ONC") in 1753. In this note I will examine and dispute Immerwahr's (...) thesis, which I believe can be shown to be seriously flawed. It is important to do so, as Immerwahr's note has been quoted a number of times in books and articles on Hume, and his thesis has been taken as gospel without sufficient examination of the grounds for his claims.2 As a consequence, Immerwahr's thesis is in danger of becoming a stubborn belief, even if not properly supportable. The controversy about Hume's racism centers on one infamous footnote added to the essay "Of National Characters" in the 1753-1754 edition of Essays and Treatises on Several Subjects. Why should we care about one footnote? We should care because the footnote seems to go against the image of a philosopher we thought we knew, and whom we likely esteem. In addition, it is shockingly bigoted. It reads in its entirety: I am apt to suspect the negroes, and in general all the other species of men (for there are four or five different kinds) to be naturally inferior to the whites. There never was a civilized nation of any other complexion than white, nor even any individual eminent either in action or speculation. No ingenious manufactures amongst them, no arts, no Aaron Garrett is at the Department of Philosophy, Boston University, 745 Commonwealth Avenue, Boston, MA 02215, USA. e-mail: garrett@bu.edu 172 Aaron Ganett sciences. On the other hand, the most rude and barbarous of the whites, such as the ancient Germans, the present Tartars, have still something eminent about them, in their valour, form of government, or some other particular. Such a uniform and constant difference could not happen, in so many countries and ages, if nature had not made an original distinction betwixt these breeds of men. Not to mention our colonies, there are Negroe slaves dispersed all over Europe, of which none ever discovered any symptom of ingenuity; tho' low people, without education, will start up amongst us, and distinguish themselves in every profession. In Jamaica, indeed, they talk of one negroe as a man of parts and learning; but 'tis likely he is admired for very slender accomplishments, like a parrot, who speaks a few words plainly.3 The footnote was not present in the 1748 edition of the Essays, Moral and Political, or Three Essays, Moral and Political, where ONC first saw light. In the 1768 edition there is one very minor alteration (from "tho' low people" to "though low people"). In the 1770 edition the footnote becomes an endnote, M,4 and there are again a few minor changes (from "betwixt these breeds of men" to "between these breeds of men"; from "of which never discovered" to "of whom never discovered"; for "'tis likely he is admired," read "it is likely he is admired") and one interesting substantive change (for "admired for very slender accomplishments," read "admired for slender accomplishments"). The most important change from the 1753 version of the note is in the 1777 posthumous edition, which Hume had corrected before he died. Hume rewrote the first two lines of 177OM, to read in 1777M: I am apt to suspect the negroes to be naturally inferior to the whites. There scarcely ever was a civilized nation of that complexion, nor even any individual eminent either in action or speculation.5 In "Hume's Revised Racism," Immerwahr argues that it is likely that Hume, after reading James Beattie's "Essay On Truth" and in light of his criticisms, revised the footnote in the 1777 edition of ONC. Immerwahr cites two pieces of evidence, a letter from Hume to Strahan to which he refers but does not quote, and Beattie's criticisms of Hume, which Hume may have read (although how much of it he read...

My favourite leading question when teaching Philosophy of Mind is ‘Could a goldfish long for its mother?’ This introduces the philosophical technique of ‘conceptual analysis’, essential for the study of mind (Sloman 1978, ch. 4). By analysing what we mean by ‘A longs for B’, and similar descriptions of emotional states we see that they inv olve rich cognitive structures and processes, i.e. computations. Anything which could long for its mother, would have to hav e some sort of representation of (...) its mother, would have to believe that she is not in the vicinity, would have to be able to represent the _possibility _of being close to her, would have to desire that possibility, and would have to be to some extent pre-occupied or obsessed with that desire. That is, it should intrude into and interfere with other activities, like admiring the scenery, catching smaller fish, etc. If the desire were there, but could be calmly put aside, whilst other interests were pursued, then it would not be truly a state of longing. It might be a state of preferring. Thus longing involves computational interrupts. The same seems to be true of all emotions. (shrink)

The left ventricular assist device was originally designed to be surgically implanted as a bridge to transplantation for patients with chronic end-stage heart failure. On the basis of the REMATCH trial, the US Food and Drug Administration and the US Centers for Medicare & Medicaid Services approved permanent implantation of the left ventricular assist device as a destination therapy in Medicare beneficiaries who are not candidates for heart transplantation. The use of the left ventricular assist device as a destination therapy (...) raises certain ethical challenges. Left ventricular assist devices can prolong the survival of average recipients compared with optimal medical management of chronic end-stage heart failure. However, the overall quality of life can be adversely affected in some recipients because of serious infections, neurologic complications, and device malfunction. Left ventricular assist devices alter end-of-life trajectories. The caregivers of recipients may experience significant burden (e.g., poor physical health, depression, anxiety, and posttraumatic stress disorder) from destination therapy with left ventricular assist devices. There are also social and financial ramifications for recipients and their families. We advocate early utilization of a palliative care approach and outline prerequisite conditions so that consenting for the use of a left ventricular assist device as a destination therapy is a well informed process. These conditions include: (1) direct participation of a multidisciplinary care team, including palliative care specialists, (2) a concise plan of care for anticipated device-related complications, (3) careful surveillance and counseling for caregiver burden, (4) advance-care planning for anticipated end-of-life trajectories and timing of device deactivation, and (5) a plan to address the long-term financial burden on patients, families, and caregivers. Short-term mechanical circulatory devices (e.g. percutaneous cardiopulmonary bypass, percutaneous ventricular assist devices, etc.) can be initiated in emergency situations as a bridge to permanent implantation of ventricular assist devices in chronic end-stage heart failure. In the absence of first-person (patient) consent, presumed consent or surrogate consent should be used cautiously for the initiation of short-term mechanical circulatory devices in emergency situations as a bridge to permanent implantation of left ventricular assist devices. Future clinical studies of destination therapy with left ventricular assist devices should include measures of recipients' quality of end-of-life care and caregivers' burden. (shrink)

Biographically speaking, this assertion recalls the mythic tale of how Royce received his appointment at Harvard after James “forgot” about Howison.2 Philosophically speaking, however, Howison’s interchange with Royce concerning his philosophical conception of God in the 1895 debate held at Berkeley was a crucial intersection of these two philosophers that set the directions for their future work. It was a chance for Howison to (...) “get it on,” in the words of John McDermott,3 with Royce, in a philosophical bout for the championship title of American Idealism.

While moral arguments for vegetarianism have been explored in great depth, the arguments for veganism seem less clear. Although many animals used for milk and eggs are forced to live miserable lives on factory farms, it’s possible to raise animals as food resources on farms where the animals are treated more humanely and never slaughtered. Under more humane conditions, do we harm animals to use them for food? I argue that, even under humane conditions, using animals for food typically harms (...) animals by restricting their freedom. My argument raises an important question about the extent to which animals are harmed when their freedom is restricted. On one view, it is possible to restrict animals’ freedom without harming them so long as we don’t make them suffer. This view underestimates the value of freedom for animals. Even if animals aren’t made to suffer, restricting their freedom can harm them insofar as it deprives them of freely pursuing their enjoyments in life. My argument has implications for not only the ethics of using animals as food resources but also the ethics of using animals in zoos and circuses. I examine these implications and also consider what we should do with farm animals if we cease using them for food. (shrink)

This paper offers a short and biased overview of the history of discussion and controversy about the role of different forms of representation in intelligent agents. It repeats and extends some of the criticisms of the `logicist' approach to AI that I first made in 1971, while also defending logic for its power and generality. It identifies some common confusions regarding the role of visual or diagrammatic reasoning including confusions based on the fact that different forms of representation may be (...) used at different levels in an implementation hierarchy. This is contrasted with the way in the use of one form of representation (e.g. pictures) can be {\em controlled} using another (e.g. logic, or programs). Finally some questions are asked about the role of metrical information in biological visual systems. (shrink)

As a step towards comprehensive computer models of communication, and effective human machine dialogue, some of the relationships between communication and affect are explored. An outline theory is presented of the architecture that makes various kinds of affective states possible, or even inevitable, in intelligent agents, along with some of the implications of this theory for various communicative processes. The model implies that human beings typically have many different, hierarchically organized, dispositions capable of interacting with new information to produce affective (...) states, distract attention, interrupt ongoing actions, and so on. High "insistence" of motives is defined in relation to a tendency to penetrate an attention filter mechanism, which seems to account for the partial loss of control involved in emotions. One conclusion is that emulating human communicative abilities will not be achieved easily.

It does so through a detailed analysis of canonical texts and recently published primary sources on two crucial concepts in Heidegger’s later thought: _Gelassenheit _and _Gestell_. _Gelassenheit_, translated as ‘releasement’, and _Gestell_, often translated as ‘enframing’ or ‘positionality’, stand as opposing ideas in Heidegger’s work whereby the meditative thinking of _Gelassenheit _counters the dangers of our technological framing of the world in _Gestell_. After opening with (...) a scholarly overview of Heidegger’s philosophy of technology as a whole, this volume focuses on important Heideggerian critiques of science, technology, and modern industrialized society as well as Heidegger’s belief that transformations in our thought processes enable us to resist the restrictive domain of modern techno-scientific practice. Key themes discussed in this collection include: the history, development, and defining features of modern technology; the relationship between scientific theories and their technological instantiations; the nature of human agency and the essence of education in the age of technology; and the ethical, political, and environmental impact of our current techno-scientific customs. With contributions from a number of renowned Heidegger scholars, the original essays in this collection will be of great interest to scholars and students of philosophy, technology studies, the history and philosophy of science, critical theory, environmental studies, education, sociology, and political theory.

Nietzsche's late works are brilliant and uncompromising, and stand as monuments to his lucidity, rigour, and style. This volume combines, for the first time in English, five of these works: The Antichrist, Ecce Homo, Twilight of the Idols, Nietzsche contra Wagner, and The Case of Wagner. Here, Nietzsche takes on some of his greatest adversaries: traditional religion, contemporary culture, and above all his one-time hero, the composer Richard Wagner. His writing is simultaneously critical and creative, putting into practice his alternative (...) philosophical vision, which, after more than a hundred years, still retains its startling novelty and audacity. These new translations aim to capture something of the style and rhythm of the original German, so that the reader can get a sense of Nietzsche as not just a philosopher but also a consummate artist, capable of 'dancing with his pen', and as untimely as he claims to be.
