The aim of this project was to explore the possibility of constructing a psychologic inference engine that might enhance introspective self-awareness by delivering inferences about a user based on what he said in interactive dialogues about his closest opposite-sex relation. To implement this aim, we developed a computer program (guru) with the capacity to simulate human conversation in colloquial natural language. The psychologic inferences offered represent the authors' simulations of their commonsense psychology responses to expected user-input expressions. The heuristics of (...) the natural language processor and its relation to output responses are described in enough detail for the operations of the implementation to be understood. Evaluation of this new cognitive agent presents, we hope, puzzles for artificial intelligence and cognitive science. (shrink)

This paper is a review of work on Newman's objection to epistemic structural realism (ESR). In Section 2, a brief statement of ESR is provided. In Section 3, Newman's objection and its recent variants are outlined. In Section 4, two responses that argue that the objection can be evaded by abandoning the Ramsey-sentence approach to ESR are considered. In Section 5, three responses that have been put forward specifically to rescue the Ramsey-sentence approach to ESR from the modern versions of (...) the objection are discussed. Finally, in Section 6, three responses are considered that are neutral with respect to one's approach to ESR and all argue (in different ways) that the objection can be evaded by introducing the notion that some relations/structures are privileged over others. It is concluded that none of these suggestions is an adequate response to Newman's objection, which therefore remains a serious problem for ESRists.

While theories of rationality and decision making typically adopt either a single-powertool perspective or a bag-of-tricks mentality, the research program of ecological rationality bridges these with a theoretically-driven account of when different heuristic decision mechanisms will work well. Here we described two ways to study how heuristics match their ecological setting: The bottom-up approach starts with psychologically plausible building blocks that are combined to create simple heuristics that fit specific environments. The top-down approach starts from the statistical problem facing the (...) organism and a set of principles, such as the bias– variance tradeoff, that can explain when and why heuristics work in uncertain environments, and then shows how effective heuristics can be built by biasing and simplifying more complex models. We conclude with challenges these approaches face in developing a psychologically realistic perspective on human rationality. (shrink)

In clinical ethics, there remains a great deal of uncertainty regarding the appropriateness of attempting cardiopulmonary resuscitation (CPR) for certain patients. Although the issue continues to receive ample attention and various frameworks have been proposed for navigating such cases, most discussions draw heavily on the notion of harm as a central consideration. In the following, I use emerging philosophical literature on the notion of harm to argue that the ambiguities and disagreement about harm create important and oft-overlooked challenges for the (...) ethics of CPR. I begin by elucidating the standard account of harm, called the Counterfactual Comparative Account (CCA). I then show that three challenges to the CCA—preemptive harms, the harm of death, and non-experiential harms—are particularly salient when assessing potential harms for candidates of CPR and likely impact-related decision-making and communication. I extend this argument to explore how the ambiguities of harm might extend to other realms of clinical decision-making, such as the use and limitations of life-sustaining treatments. To address these challenges, I propose two strategies for identifying and minimizing the impact of such uncertainty: first, clinicians and ethicists ought to promote pluralistic conversations that account for different understandings of harm; second, they ought to invoke harm-independent considerations when discussing the ethics of CPR in order to reflect the nuances of such conversations. These strategies, coupled with a richer philosophical understanding of harm, promise to help clinicians and ethicists navigate the prevalent and difficult cases involving patient resuscitation and many other harm-based decisions in the clinical setting.

_Purpose:_ In order to develop an evidence-based, sport-specific minimum impairment criteria (MIC) for the sport of vision-impaired (VI) shooting, this study aimed to determine the relative influence of losses in visual acuity (VA) and contrast sensitivity (CS) on shooting performance. Presently, VA but not CS is used to determine eligibility to compete in VI shooting. _Methods:_ Elite able-sighted athletes ( n = 27) shot under standard conditions with their habitual vision, and with their vision impaired by the use of simulation (...) spectacles (filters which reduce both VA and CS) and refractive blur (lenses which reduce VA with less effect on CS). Habitual shooting scores were used to establish a cut-off in order to determine when shooting performance was ‘below expected’ in the presence of vision impairment. Logistic regression and decision tree analyses were then used to assess the relationship between visual function and shooting performance. _Results:_ Mild reductions in VA and/or CS did not alter shooting performance, with greater reductions required for shooting performance to fall below habitual levels (below 87% of normalized performance). Stepwise logistic regression selected CS as the most significant predictor of shooting performance, with VA subsequently improving the validity of the model. In an unconstrained decision tree analysis, CS was selected as the sole criterion (80%) for predicting ‘below expected’ shooting score. _Conclusion:_ Shooting performance is better predicted by losses in CS than by VA. Given that it is not presently tested during classification, the results suggest that CS is an important measure to include in testing for the classification of vision impairment for athletes competing in VI shooting.

For most of the history of metaphysics, the subject has been dominated by the concept of substance. There is an everyday commonsense notion of substance which is perfectly harmless and which I shall defend against attempts to remove it or revise it away. But I deny that substance has to be construed as a primitive even in everyday terms. Borrowing Strawson’s distinction between descriptive and revisionary metaphysics, I press the legitimate claims of revisionary metaphysics and argue that there is no (...) place for a fundamental concept of substance within it, although aspects of the concept are likely to find their place therein.

The relationship of part to whole is one of the most fundamental there is, yet until now there has been no full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. This has far-reaching consequences for our understanding of such classical philosophical (...) concepts as identity, individual, class, substance and accident, matter, form, essence, dependence, and integral whole. It also enables the author to offer new solutions to long-standing problems surrounding these concepts, such as the Ship of Theseus Problem and the issue of mereological essentialism. The author shows by his use of formal techniques that classical philosophical problems are amenable to rigorous treatment, and the book represents a synthesis of issues and methods from the analytical tradition and from the older continental realist tradition of Brentano and the early Husserl.

Drawing on Ciceronian rhetorical tropes, Thomas Aquinas treats the rite of the Eucharist in terms of the classical ars memoriae. The Eucharist, for Aquinas, is the schooling in desire whereby we are trained to order the associations of our memory to their proper objects in terms of their relations to God. He thus conceives of the liturgy of the Mass as rhetoric proper, which truly teaches, moves and delights. Since memory is the condition of all thought, as both Thomas and (...) Augustine claim, the Eucharist is the “site” of all theological production, and therefore the liturgy is the art of memory of which all other similar arts are derivative. (shrink)

How can anyone be rational in a world where knowledge is limited, time is pressing, and deep thought is often an unattainable luxury? Traditional models of unbounded rationality and optimization in cognitive science, economics, and animal behavior have tended to view decision-makers as possessing supernatural powers of reason, limitless knowledge, and endless time. But understanding decisions in the real world requires a more psychologically plausible notion of bounded rationality. In Simple heuristics that make us smart (Gigerenzer et al. 1999), we (...) explore fast and frugal heuristics – simple rules in the mind's adaptive toolbox for making decisions with realistic mental resources. These heuristics can enable both living organisms and artificial systems to make smart choices quickly and with a minimum of information by exploiting the way that information is structured in particular environments. In this précis, we show how simple building blocks that control information search, stop search, and make decisions can be put together to form classes of heuristics, including: ignorance-based and one-reason decision making for choice, elimination models for categorization, and satisficing heuristics for sequential search. These simple heuristics perform comparably to more complex algorithms, particularly when generalizing to new data – that is, simplicity leads to robustness. We present evidence regarding when people use simple heuristics and describe the challenges to be addressed by this research program. Key Words: adaptive toolbox; bounded rationality; decision making; elimination models; environment structure; heuristics; ignorance-based reasoning; limited information search; robustness; satisficing; simplicity.

In his recent work, ‘Sport, Aesthetic Experience, and Art as the Ideal Embodied Metaphor’, Tim L. Elcombe explores links between sport and art from a pragmatically informed conception of aesthetic experience. However, Elcombe's work does not highlight the role of the imagination in the interpretation of the aesthetic something Michael Polanyi claims to be the ‘cornerstone of aesthetic theory’. With the backdrop of an increased interest in the aesthetics, phenomenology, and epistemology of sport, this discussion essay seeks to defend the (...) usefulness and value of definitional demarcation debates between sport and art, to use Polanyi’s distinctions among technical, scientific and artistic problems to support the claim that sport is not art, and to offer an account of how sport contributes in its own way to human flourishing and why it is no less valuable experientially than art.

This paper argues that Badiou's and Lacan's theorizations of ethics offer a way to formulate an ethics of teaching and to explore what such an ethics might look like when teachers encounter events that disrupt their quotidian lives. Relying on the work of Badiou and Lacan, the paper critiques mainstream approaches to the ethics of teaching and sketches an alternative pedagogical ethics.

RAID-II is a high-bandwidth, network-attached storage server designed and implemented at the University of California at Berkeley. In this paper, we measure the performance of RAID-II and evaluate various architectural decisions made during the design process. We first measure the end-to-end performance of the system to be approximately 20 MB/s for both disk array reads and writes. We then perform a bottleneck analysis by examining the performance of each individual subsystem and conclude that the disk subsystem limits performance. By adding (...) a custom interconnect board with a high-speed memory and bus system and parity engine, we are able to achieve a performance speedup of 8 to 15 over a comparative system using only off-the-shelf hardware.

Savage et al. and Mehr et al. provide well-substantiated arguments that the evolution of musicality was shaped by adaptive functions of social bonding and credible signalling. However, they are too quick to dismiss byproduct explanations of music evolution, and to present their theories as complete unitary accounts of the phenomenon.

rené descartes famously and explicitly rejects appeals to final causes in natural philosophy, suggesting that such appeals depend on knowledge of God’s inscrutable ends.For since I now know that my own nature is very weak and limited, whereas the nature of God is immense, incomprehensible and infinite, I also know without more ado that he is capable of countless things whose causes are beyond my knowledge. And for this reason alone I consider the whole kind of causes, customarily sought from (...) an end, to be totally useless in physics; there is considerable rashness in thinking myself capable of investigating God’s ends.1This rejection did not go unnoticed nor without controversy.
