Magicians use misdirection to prevent you from realizing the methods used to create a magical effect, thereby allowing you to experience an apparently impossible event. Magicians have acquired much knowledge about misdirection, and have suggested several taxonomies of misdirection. These describe many of the fundamental principles in misdirection, focusing on how misdirection is achieved by magicians. In this article we review the strengths and weaknesses of past taxonomies, and argue that a more natural way of making sense of misdirection is (...) to focus on the perceptual and cognitive mechanisms involved. Our psychologically-based taxonomy has three basic categories, corresponding to the types of psychological mechanisms affected: perception, memory, and reasoning. Each of these categories is then divided into subcategories based on the mechanisms that control these effects. This new taxonomy can help organize magicians' knowledge of misdirection in a meaningful way, and facilitate the dialog between magicians and scientists. (shrink)

Our perceptual experience is largely based on prediction, and as such can be influenced by knowledge of forthcoming events. This susceptibility is commonly exploited by magicians. In the Vanishing Ball Illusion, for example, a magician tosses a ball in the air a few times and then pretends to throw the ball again, whilst secretly concealing it in his hand. Most people claim to see the ball moving upwards and then vanishing, even though it did not leave the magician’s hand (Kuhn (...) & Land, 2006; Triplett, 1900). But what exactly can such illusions tell us? We investigated here whether seeing a real action before the pretend one was necessary for the Vanishing Ball Illusion. Participants either saw a real action immediately before the fake one, or only a fake action. Nearly one third of participants experienced the illusion with the fake action alone, while seeing the real action beforehand enhanced this effect even further. Our results therefore suggest that perceptual experience relies both on long-term knowledge of what an action should look like, as well as exemplars from the immediate past. In addition, whilst there was a forward displacement of perceived location in perceptual experience, this was not found for oculomotor responses, consistent with the proposal that two separate systems are involved in visual perception.

The biggest benefit of dual-process theory lies in its role as a benchmark theory that, regardless of its empirical plausibility, serves as a starting point for better and more domain-specific models. In this sense, dual-process theory is the Barbapapa of psychological theory – a blob-shaped creature that can be reshaped and adapted to fit in the context of any human behavior.

When assessing the cost effectiveness of health care programmes, health economists typically presume that distant events should be given less weight than present events. This article examines the moral reasonableness of arguments advanced for positive discounting in cost-effectiveness analysis both from an intergenerational and an intrapersonal perspective and assesses if arguments are equally applicable to health and monetary outcomes. The article concludes that behavioral effects related to time preferences give little or no reason for why society at large should favour (...) the present over the future when making intergenerational choices regarding health. The strongest argument for discounting stems from the combined argument of diminishing marginal utility in the presence of growth. However, this hinges on the assumption of actual growth in the relevant good. Moreover, current modern democracy may be insufficiently sensitive to the concerns of future generations. The second part of the article categorises preference failures (which justify paternalistic responses) into two distinct groups, myopic and acratic. The existence of these types of preference failures makes elicited time preferences of little normative relevance when making decisions regarding the social discount rate, even in an intrapersonal context. As with intergenerational discounting, the combined arguments of growth and diminishing marginal utility offer the strongest arguments for discounting in the intrapersonal context. However, there is no prima facie reason to assume that this argument should apply equally to health and monetary values. To be sure, selecting an approach towards discounting health is a complex matter. However, the life-or-death implications of any approach require that the discussion not be downplayed to merely a technical matter for economists to settle. (shrink)

The recent philosophy of physics is confronted with the new ontology, as it emerges after philosophy proper has fully articulated the linguistic turn. The classical ontologists asserted or denied, controversially, that certain entities "existed." Rather than adding to these controversies, the new ontology uncovers their dialectics. The ontologically problematic entities of physics are of two kinds, represented by forces and particles, respectively. The dialectics has been dominated by eight patterns. Two of these, independence and realism, belong to philosophy proper. The (...) latter is here considered in order to relieve the philosophy of physics of a burden only philosophy proper can bear. That leaves six patterns: concreteness (including the orbit feature), acquaintance, simplicity, significance, process, and model. The paper sketches how each of these may be used and probably has been used, either explicitly or implicitly, in the recent controversies. (shrink)

Positivists and phenomenalists of all sorts maintain, and long have maintained, some variant of the following thesis concerning the existence of physical objects: Such statements as ‘There is now a wall behind my back’ are synonymous with a class of statements of which the following is representative ‘If I shall turn my head, then I shall also have the visual experience called ‘seeing a wall'.’ This amounts to proposing what many of us call a philosophical analysis of ‘exist’ or, more (...) precisely, of one meaning of ‘exist'; for the thesis implies that this verb, in the sense in which we use it when we say ‘This wall exists', is dispensable in the sense of being definable. Realists, who oppose the thesis, hold that ‘exist', in the sense mentioned, is what I would call an undefined descriptive predicate; and then they go on to recommend that instead of defining existence in terms of what we see, we had better say that we shall, if we turn, see a wall because there is a wall. Thus one could say, perhaps, that the realists wish to convert the positivistic position; instead of founding existence upon experience, they want to found experience upon existence. To be sure, this is but a bare and crudely formulated schema of an issue that has been argued for a long time. Also, contemporary analysts for the most part do not discuss the issue directly; they give their attention to preliminary and, therefore, more fundamental questions. Like experienced chess players, who know to which characteristic situations in the middle game certain openings will eventually lead, we try to convince each other of the excellence of our respective openings. There is, in particular, one fundamental or opening move that is now widely discussed and which, I believe, most of us examine with a view to the position in which we shall find ourselves—in the middle game—with respect to the realism issue. I refer to the clarification of the relations between meaning and verification or, to put it the way positivists do, to the formulation of an adequate meaning criterion. Let me indicate the connection between these questions and the crude schema I have given for the realism issue. According to current garden varieties of positivism, a statement is meaningful if it is verifiable by experience. ‘There is a wall behind my back’ is, in this view, meaningful because it is synonymous with a class of statements each of which is verifiable by future experience. More pointedly, the familiar common sense statements about the existence of physical objects are considered as meaningful because they are verifiable. This has again the subjectivistic ring realists dislike so much; so they may again be inclined to convert the positivistic position, if only tentatively and because they feel that a piece of realistic common sense would thus be preserved. But to make the conversion is to say that ‘There is a wall behind my back’ is verifiable because it is meaningful. (shrink)

This article argues that the tradition within the individualism-holism debate of importing arguments from the micro–macro discussion in other disciplines significantly has hampered our understanding of the “individual-social” relationship. While, for example, the “neural-mental” and “atomic-molecular” links represent empirical “gives rise to” relationships, in the social sciences the micro–macro link is a purely analytical “qualifies as” type of relationship. This disanalogy is important, since it has significant implications for the individualism-holism debate: it implies a phenomenally monist social ontology and it (...) disqualifies the notion of social macro causation.

1. In his paper “On Denoting” Russell points out what he calls a puzzle every satisfactory theory of denoting will have to solve. Of the three sentences George IV. wished to know whether Scott was the author of WaverleyScott is the author of WaverleyGeorge IV. wished to know whether Scott was Scott the first two, and, are presumably true, while the third,, is presumably false. The reason given for considering this arrangement of truth values a puzzle is that the ‘is’ (...) in signifies identity; that the proper name ‘Scott’ and the descriptive phrase ‘the author of Waverley’ denote the same object; and that, therefore, if the latter is replaced by the former in the true sentence, the resulting sentence,, should again be true. Yet is false, or, as one also says, the context considered is nonextensional with respect to this replacement. (shrink)

In this article, I examine Reiner Schürmann’s interpretation of Nietzsche’s critique of subjectivity. By focusing on Nietzsche’s reflections on the difference between weight and lightness, I analyze Nietzsche’s critique of the appropriative nature of man and relate it to his understanding of the expropriative tendency in human existence. In the second part of the article, this Nietzschean understanding of subjectivity is developed through Schürmann’s interpretation of Nietzsche. Here, the onus is placed on Schürmann’s understanding of “the will to power.” For (...) Schürmann, the will to power is the completion of man’s appropriative nature at the same time as it is points beyond subjectivity and towards an understanding of man as an expropriative being. The aim of the article is to show up Nietzsche’s importance for Schürmann’s thought and to investigate how his interpretation can shed light on what existence would become if it transcended the limits of the appropriating subject.

The following remarks have been stimulated by Mr. A. J. Ayer's recent essay “The Terminology of Sense Data.” In this paper Mr. Ayer restates several of the points he has made in his book The Foundations of Empirical Knowledge. The context of his argument is that of the traditional distinction between two kinds of things, sense data, percepts, phenomenal or direct given-nesses on the one hand and so-called physical objects on the other. In this context, Mr. Ayer's argument is, to (...) my mind, very admirable; so I do not intend to comment on it. In some other contexts, some of his formulations may, I fear, give rise to misunderstandings; these, naturally, are the points on which I wish to comment. But before specifying them, I had better make sure that we are talking about the same thing by briefly restating several of Mr. Ayer's points. With some of these, if I understand them correctly, I find myself in agreement; the merit of some others I shall presently examine. (shrink)
