Four experiments are reported which investigated the types of truth tables that people associate with conditional sentences and the kinds of inferences that they will draw from them. The present studies differed from most previous ones in using different types of content in the conditionals, for example promises and warnings. It was found that the type of content had a strong and consistent effect on both truth tables and inferences. It is suggested that this is because in real life conditionals (...) make probabilistic assertions, and that the strength of the probabilistic link is determined by the situation in which the conditional occurs. The implications of these findings for current theories of reasoning are considered and it is concluded that none of them is entirely satisfactory. It is suggested that more linguistically based theories may prove more successful. (shrink)

Many researchers have suggested that premise interpretation errors can account, at least in part, for errors on categorical syllogisms. However, although it is possible to show that people make such errors in simple inference tasks, the evidence for them is far less clear when actual syllogisms are administered. Part of the problem is due to the lack of clear predictions for the solutions that would be expected when using modified quantifiers, assuming that correct inferences are made from them. This paper (...) presents the expected solutions for Gricean, reversible, and reversible Gricean interpretations, and evaluates these using three datasets (two currently available, and one new). The evidence supported the adoption of reversible and reversible Gricean interpretations, but not Gricean interpretations on their own. These results suggest that the categorical syllogism task tends to induce different quantifier interpretations from those identified in simple inference tasks. (shrink)

Stanovich & West's claim that there are two coherent and conceptually distinct types of thinking, System 1 and System 2, is questioned. Some authors equate System 2 with intelligence whereas other do not; and some authors regard the two types of system as distinct while others regard them as lying on a continuum.

Two studies are reported which demonstrate that analytic responding on everyday reasoning problems can be increased and bias eliminated after training on the law of large numbers. Critical thinking problems involving belief-consistent, neutral, and inconsistent conclusions were presented. Belief bias was eliminated when a written justification of argument strength was elicited. However, belief-based responding was still evident when evaluations of the arguments were elicited using rating scales. This finding demonstrates a dissociation between analytic and belief-based responding as a function of (...) response format. In Experiment 2 an instructional condition designed to foster decontextualised reasoning was included but was ineffective in reducing the degree to which judgements were biased by beliefs. It was concluded that training which makes available the analytic strategies necessary to evaluate a problem has the potential to facilitate performance only if the requested response triggers conscious deliberation of the evidence.

(1994). Inductive reasoning, deductive reasoning and mental models. International Studies in the Philosophy of Science: Vol. 8, No. 1, pp. 65-67. doi: 10.1080/02698599408573483.

The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

The notion of ecological rationality, although plausible, does not readily lead to testable predictions. This is illustrated with respect to heuristics in syllogistic reasoning. Several possible heuristics have been proposed but ecological rationality does not appear to offer a sensible rationale for choosing between these.

Girotto and Legrenzi's 1993 facilitation effect for their SARS version of Wason s THOG problem a disjunctive reasoning task was examined. The effect was not replicated when the standard THOG problem instructions were used in Experiments 1 and 2. However, in Experiment 3 when Girotto and Legrenzi's precise instructions were used, facilitation was observed. Experiment 4 further investigated the role of the type of instructions in the observed facilitation. The results suggest that such facilitation may result from attentional factors rather (...) than the use of a combinatorial analysis in the problem. (shrink)

This essay analyzes the provocative image of the bodhisattva, the saint of the Indian Mahayana Buddhist tradition, descending into the hell realms to work for the benefit of its denizens. Inspired in part by recent attempts to naturalize Buddhist ethics, I argue that taking this ‘mythological’ image seriously, as expressing philosophical insights, helps us better understand the shape of Mahayana value theory. In particular, it expresses a controversial philosophical thesis: the claim that no amount of physical pain can disrupt the (...) flourishing of a fully virtuous person. I reconstruct two related elements of early Buddhist psychology that help us understand this Mahayana position: the distinction between hedonic sensation and virtuous or nonvirtous mental states ; and the claim that humans are massively deluded as to what constitutes well-being. Doing so also lets me emphasize the continuity between early Buddhist and Mahayana traditions in their views on well-being and flourishing. (shrink)

Santideva's 8th century Mahayana Buddhist classic, the Guide to the Practices of Awakening (Bodhicaryavatara), has been a source of philosophical inspiration in the Indian and Tibetan traditions for over a thousand years. Stephen Harris guides us through a philosophical exploration of Santideva's masterpiece, introducing us to his understanding of the compassionate bodhisattva, who vows to liberate the entire universe from suffering. Individual chapters provide studies of the bodhisattva virtues of generosity, patience, compassion, and wisdom, illustrating the role each plays (...) in Santideva's account of well-being and moral development. Harris also provides in-depth analysis of many of Santideva's most influential arguments, demonstrating how he employs reasoning as a method to cultivate moral character. (shrink)

Bioethics is a field of inquiry and as such is fundamentally an epistemic discipline. Knowing how we make moral judgments can bring into relief why certain arguments on various bioethical issues appear plausible to one side and obviously false to the other. Uncertain Bioethicsmakes a significant and distinctive contribution to the bioethics literature by culling the insights from contemporary moral psychology to highlight the epistemic pitfalls and distorting influences on our apprehension of value. Stephen Napier also incorporates research from (...) epistemology addressing pragmatic encroachment and the significance of peer disagreement to justify what he refers to as epistemic diffidence when one is considering harming or killing human beings. Napier extends these developments to the traditional bioethical notion of dignity and argues that beliefs subject to epistemic diffidence should not be acted upon. He proceeds to apply this framework to traditional and developing issues in bioethics including abortion, stem cell research, euthanasia, decision-making for patients in a minimally conscious state, and risky research on competent human subjects. to traditional and developing issues in bioethics including abortion, stem cell research, euthanasia, decision-making for patients in a minimally conscious state, and risky research on competent human subjects.

The Limits of Influence is a detailed examination and defense of the evidence for largescale-psychokinesis . It examines the reasons why experimental evidence has not, and perhaps cannot, convince most skeptics that PK is genuine, and it considers why traditional experimental procedures are important to reveal interesting facts about the phenomena.

The relations among consciousness, brain, behavior, and scientific explanation are explored in the domain of color perception. Current scientific knowledge about color similarity, color composition, dimensional structure, unique colors, and color categories is used to assess Locke.

Why are people interested in money? Specifically, what could be the biological basis for the extraordinary incentive and reinforcing power of money, which seems to be unique to the human species? We identify two ways in which a commodity which is of no biological significance in itself can become a strong motivator. The first is if it is used as a tool, and by a metaphorical extension this is often applied to money: it is used instrumentally, in order to obtain (...) biologically relevant incentives. Second, substances can be strong motivators because they imitate the action of natural incentives but do not produce the fitness gains for which those incentives are instinctively sought. The classic examples of this process are psychoactive drugs, but we argue that the drug concept can also be extended metaphorically to provide an account of money motivation. From a review of theoretical and empirical literature about money, we conclude that (i) there are a number of phenomena that cannot be accounted for by a pure Tool Theory of money motivation; (ii) supplementing Tool Theory with a Drug Theory enables the anomalous phenomena to be explained; and (iii) the human instincts that, according to a Drug Theory, money parasitizes include trading (derived from reciprocal altruism) and object play.

For over thirty years, Stephen Braude has studied the paranormal in everyday life, from extrasensory perception and psychokinesis to mediumship and materialization. _The Gold Leaf Lady and Other Parapsychological Investigations_ is a highly readable and often amusing account of his most memorable encounters with such phenomena. Here Braude recounts in fascinating detail five particular cases—some that challenge our most fundamental scientific beliefs and others that expose our own credulousness. Braude begins with a south Florida woman who can make thin (...) gold-colored foil appear spontaneously on her skin. He then travels to New York and California to test psychokinetic superstars—and frauds—like Joe Nuzum, who claim to move objects using only their minds. Along the way, Braude also investigates the startling allegations of K.R., a policeman in Annapolis who believes he can transfer images from photographs onto other objects—including his own body—and Ted Serios, a deceased Chicago elevator operator who could make a variety of different images appear on Polaroid film. Ultimately, Braude considers his wife’s surprisingly fruitful experiments with astrology, which she has used to guide professional soccer teams to the top of their leagues, as well as his own personal experiences with synchronicity—a phenomenon, he argues, that may need to be explained in terms of a refined, extensive, and dramatic form of psychokinesis. Heady, provocative, and brimming with eye-opening details and suggestions, _The Gold Leaf Lady and Other Parapsychological Investigations_ will intrigue both adherents and detractors of its controversial subject matter alike.

This article explores five important issues relating to the evaluation of ethics education in accounting. The issues that are considered include: (a) reasons for evaluating accounting ethics education (see Caplan, 1980, pp. 133–35); (b) goal setting as a prerequisite to evaluating the outcomes of accounting ethics education (see Caplan, 1980, pp. 135–37); (c) possible broad levels of outcomes of accounting ethics education that can be evaluated; (d) matters relating to accounting ethics education that are in need of evaluation (see Caplan, (...) 1980, p. 136); and (e) possible techniques for measuring outcomes of accounting ethics education (see Caplan, 1980, pp. 144–49). The paper concludes with a discussion of the issues under consideration. (shrink)

This article explores the defense Indian Buddhist texts make in support of their conceptions of lives that are good for an individual. This defense occurs, largely, through their analysis of ordinary experience as being saturated by subtle forms of suffering . I begin by explicating the most influential of the Buddhist taxonomies of suffering: the threefold division into explicit suffering , the suffering of change , and conditioned suffering . Next, I sketch the three theories of welfare that have been (...) most influential in contemporary ethical theory. I then argue that Buddhist texts underdetermine which of these theories would have been accepted by ancient Indian Buddhists. Nevertheless, Buddhist ideas about suffering narrow the shape any acceptable theory of welfare may take. In my conclusion, I argue that this narrowing process itself is enough to reconstruct a philosophical defense of the forms of life endorsed in Buddhist texts. (shrink)

Bergson’s model of time (1889) is perhaps the proto-phenomenological theory. It is part of a larger model of mind (1896) which can be seen in modern light as describing the brain as supporting a modulated wave within a holographic field, specifying the external image of the world, and wherein subject and object are differentiated not in terms of space, but of time. Bergson’s very concrete model is developed and deepened with Gibson’s ecological model of perception. It is applied to the (...) problems of consciousness, direct realism, qualia and illusions. The model implies an entirely different basis for memory and cognition, and a brief overview is given for the basis of direct memory, compositionality and systematicity. (shrink)

In the Philosophy of Sport literature, play has been widely conceived, in whole or part, as an autotelic activity; that is, an activity pursued for intrinsic factors. I examine several versions of the conception of play as an autotelic activity. Given these different accounts, I raise the question whether the concept of autotelic play is tenable. I examine three possibilities: (i) accept the concept of autotelic play and reject the possibility of satisfying the conditions for play activities; (ii) accept the (...) concept and acknowledge that play refers to a range of activities ranging from the purely autotelic to something less; and, (iii) reject the definition of play as an autotelic activity and redefine play. I argue that the third option is the best avenue for constructing a viable account of play. In defending this third option, I argue that play activities are value laden, that the value of play is an empirical matter, and that the effect of motivating reasons on behavior is the basis for determining which motivating reasons count as intrinsic or extrinsic. I conclude that the weight of the arguments suggest we would be well-served to redefine and move beyond the notion of autotelic play. (shrink)

Bergson's 1896 theory of perception/memory assumed a framework anticipating the quantum revolution in physics, the still unrealized implications of this framework contributing to the large neglect of Bergson today. The basics of his model are explored, including the physical concepts he advanced before the crisis in classical physics, his concept of perception as ‘virtual action’ with its relativistic implications, and his unique explication of the subject/object relationship. All form the basis for his solution to the ‘hard’ problem. The relation between (...) Bergson and Gibson as natural complements is also explored, with Bergson providing the framework that explicates Gibson's concept of direct perception, with Gibson's resonance model as a precursor to dynamic systems models of the brain and his reliance on invariance laws defining perceived events providing more detail for the mechanisms Bergson only envisioned from afar, and with Bergson providing the basis for an otherwise missing Gibsonian model of direct memory.

What is art's relationship to play? Those interested in this question tend to look to modern philosophy for answers, but, as this book shows, the question was already debated in antiquity by luminaries like Plato and Aristotle. Over the course of eight chapters, this book contextualizes those debates, and demonstrates their significance for theoretical problems today. Topics include the ancient child psychology at the root of the ancient Greek word for 'play', the numerous toys that have survived from antiquity, and (...) the meaning of play's conceptual opposite, the 'serious'. What emerges is a concept of play markedly different from the one we have inherited from modernity. Play is not a certain set of activities which unleashes a certain feeling of pleasure; it is rather a certain feeling of pleasure that unleashes the activities we think of as 'play'. As such, it offers a new set of theoretical challenges. (shrink)

The popular impression of Epicurean hedonism is that it advocates a life of sensual delights. Scholars know, however, that this impression is mistaken, both because of the overall conceptual structure of Epicurus’ ethics and because Epicurus prominently and repeatedly expressed such ideas as this.

A common approach to explaining the perception of form is through the use of static features. The weakness of this approach points naturally to dynamic definitions of form. Considering dynamical form, however, leads inevitably to the need to explain how events are perceived as time-extended—a problem with primacy over that even of qualia. Optic flow models, energy models, models reliant on a rigidity constraint are examined. The reliance of these models on the instantaneous specification of form at an instant, t, (...) or across a series of such instants forces the consideration of the primary memory supporting both the perception of time-extended events and the time-extension of consciousness. This cannot be reduced to an integration over space and time. The difficulty of defining the basis for this memory is highlighted in considerations of dynamic form in relation to scales of time. Ultimately, the possibility is raised that psychology must follow physics in a more profound approach to time and motion. (shrink)

In their exhaustive study of the cognitive operation of analogy, Hofstadter and Sander arrive at a paradox: the creative and inexhaustible production of analogies in our thought must derive from a “reminding” operation based upon the availability of the detailed totality of our experience. Yet the authors see no way that our experience can be stored in the brain in such detail nor do they see how such detail could be accessed or retrieved such that the innumerable analogical remindings we (...) experience can occur. Analogy creation, then, should not be possible. The intent here is to sharpen and deepen our understanding of the paradox, emphasizing its criticality. It will be shown that the retrieval problem has its origins in the failure of memory theory to recognize the actual dynamic structure of events. This structure is comprised of invariance laws as per J. J. Gibson, and this event “invariance structure” is exactly what supports Hofstadter and Sander’s missing mechanism for analogical reminding. Yet these structures of invariants, existing only over optical flows, auditory flows, haptic flows, etc., are equally difficult to imagine being stored in a static memory, and thus only exacerbate the problem of the storage of experience in the brain. A possible route to the solution of this dilemma, based in the radical model of Bergson, is also sketched. (shrink)

Crimes of Reason brings together expanded and updated versions of some of Braude’s best previously published essays, along with new essays written specifically for this book.

In proposing that their model can operate in the concrete, perceptual world, Rogers & McClelland (R&M) have not done justice to the complexities of the ecological sphere and its invariance laws. The structure of concrete events forces a different framework, both for retrieval of events and concepts defined across events, than that upon which the proposed model, rooted in essence in the verbal learning tradition, implicitly rests.

This paper reconstructs an Indian Buddhist response to the overdemandingness objection, the claim that a moral theory asks too much of its adherents. In the first section, I explain the objection and argue that some Mahāyāna Buddhists, including Śāntideva, face it. In the second section, I survey some possible ways of responding to the objection as a way of situating the Buddhist response alongside contemporary work. In the final section, I draw upon writing by Vasubandhu and Śāntideva in reconstructing a (...) Mahāyāna response to the objection. An essential component of this response is the psychological transformation that the bodhisattva achieves as a result of realizing the nonexistence of the self. This allows him to radically identify his well-being with the well-being of others, thereby lessening the tension between self and others upon which the overdemandingness objection usually depends. Emphasizing the attention Mahāyāna authors pay to lessening moral demandingness in this way increases our appreciation of the philosophical sophistication of their moral thought and highlights an important strategy for responding to the overdemandingness objection that has been underdeveloped in contemporary work.
