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)

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.

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.

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)

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.

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)

A central theme throughout the impressive series of philosophical books and articles Stephen Toulmin has published since 1948 is the way in which assertions and opinions concerning all sorts of topics, brought up in everyday life or in academic research, can be rationally justified. Is there one universal system of norms, by which all sorts of arguments in all sorts of fields must be judged, or must each sort of argument be judged according to its own norms? In The (...) Uses of Argument Toulmin sets out his views on these questions for the first time. In spite of initial criticisms from logicians and fellow philosophers, The Uses of Argument has been an enduring source of inspiration and discussion to students of argumentation from all kinds of disciplinary background for more than forty years.

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.

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)

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.

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.

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.

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.

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)

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.

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 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.

Stephen Whicher's Freedom and Fate begins with a tribute to Ralph Rusk's monumental biography The Life of Ralph Waldo Emerson, acknowledging its supremacy as a factual telling of Emerson's life that cannot be surpassed. Whicher's book aims to be a complement to the painstakingly researched outer life of Emerson by focusing on the great sage's inner life—not just his intellectual biography but the very nature of his thinking. Whicher stresses the life of "spectator-ship" that the young Emerson, perpetually ill (...) as he turned out to be, was condemned to. His writings, especially his private thoughts recorded in his journals, document the ebb and flow of his spirit, alternatively listless and resolute. (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.

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)

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.

In lieu of an abstract, here is a brief excerpt of the content:Multiple Personality and Moral ResponsibilityStephen E. Braude (bio)AbstractThe philosophical literature on multiple personality has focused primarily on problems about personal identity and psychological explanation. But multiple personality and other dissociative phenomena raise equally important and even more urgent questions about moral responsibility, in particular: In what respect(s) and to what extent should a multiple be held responsible for the actions of his/her alternate personalities? Cases of dreaming help illustrate (...) why attributions of responsibility in cases of dissociation do not turn on putative changes in identity, as some have supposed. Instead, it is argued that traditional criteria of rationality and behavioral control apply also to cases of dissociation. It is noted, however, that one can distinguish different kinds of responsibility in cases of dissociation, and that one is responsible for one’s dreams in a different sense from that in which one is responsible for actions one can control and evaluate. It is also argued that in cases of multiple personality it is important to distinguish control over switching of personalities from an alter’s control over its own behavior. Moreover, the author considers reasons for thinking that amnesia is less relevant to attributions of responsibility than many have supposed.Keywordsdissociation, dreaming, rationality, amnesiaIntroductionThe philosophical literature on MPD/DID 1 has focused primarily on problems about personhood, personal identity, and the nature of psychological explanation. Presumably, that is because multiples appear to be (or to harbor) more than one person or more than one distinct moral or prudential agent. But philosophers have had almost nothing to say about problems of responsibility in these cases—in particular, the question: In what respect(s) and to what extent should a multiple be held responsible for the actions of his/her alternate personalities (or alters)?Unlike questions about personhood and identity, this question is not simply an abstract matter that we may ponder at our leisure. Clinicians treating multiples must decide whether it is appropriate—or even just therapeutically beneficial—to hold their patients (or specific alters) responsible for behaviors which they seem unable to control or remember. Similarly, and with increasing frequency, our courts must decide whether a defendant claiming to be a multiple may be held guilty for the actions of one or more alters. In fact, the legal issues can be quite dramatic, and even bizarre. Consider: What sort of individual is standing trial? An alter or the multiple as a whole? Should courts accept the claim that the subject being questioned on the stand is not the same as the subject who committed the crime? If so, other questions come immediately to mind. For example, would it be appropriate for each alter of a criminal defendant to have separate legal council?Undoubtedly, some will have trouble taking that last question seriously. But no matter how [End Page 37] clear its solution may appear to one’s moral or legal intuitions, those intuitions are seldom as straightforward as they seem. Indeed, one cannot explain or defend them without taking a stand, at least provisionally, on a wide range of thorny philosophical problems. Moreover, the aforementioned questions are merely the tip of the iceberg, and our answers to them have implications extending beyond the courtroom. For example, with regard to forensic contexts Slovenko (1991) asks,Should a search or arrest warrant be issued for each personality? Must a Miranda warning be given to each personality of a suspect with MPD? May the other personalities exclude evidence on the ground that they were not properly read their rights at the time of the arrest? Would each one of the personalities have to waive his or her rights, or would one waiver be sufficient? Does the doctrine of double jeopardy bar the trial of a personality when another has been put to trial? Must each personality testifying at trial be sworn in and administered the oath?(22, 25)These questions have obvious analogues in clinical situations, and also in personal contexts, say, between friends or members of a family, one of whom is a multiple. For example, to what extent should a DID patient be held responsible for the sociopathic (or simply counter-therapeutic) behavior of... (shrink)
