Though individual categorization or decision processes have been studied separately in many previous investigations, few studies have investigated how they interact by using a two-stage task of first categorizing and then deciding. To address this issue, we investigated a categorization-decision task in two experiments. In both, participants were shown six faces varying in width, first asked to categorize the faces, and then decide a course of action for each face. Each experiment was designed to include three groups, and for each (...) group, we manipulated the probabilistic contingencies between stimulus, category assignments, and decision consequences. For each group, each participant received three different sequences of category response, category feedback, decision response, and decision feedback. We found that participants were only partially responsive in the appropriate directions to the contingencies assigned to each group. Comparisons of results from different sequences provided evidence for empirical interference effects of categorization on decisions. The empirical interference effect is defined as the difference between the probability of taking a hostile action in decision-alone conditions and the total probability of taking a hostile action in categorization-decision conditions. To test competing accounts for multiple empirical results, including two-stage choice probabilities and empirical interference effects, we compared a quantum cognition model versus a two-stage exemplar categorization model at both aggregate and individual levels. Using a Bayesian information criterion, we found that the quantum model provided an overall better model fit than the exemplar model. Although both models predicted empirical interference effects, the exemplar model was able to generate probabilistic deviation by incorporating category information of the first stage into the feature representation of the subsequent decision stage, while the quantum model produced interference effect by superposition, measurement, and quantum entanglement.

The philosophical papers comprising this volume range from process metaphysics and theology, through the phenomenological study of intentionality, to the foundations of geometry and of the system of real numbers. New light, it is thought, is shed on all these topics, some of them being of the highest interest and under intensive investigation in contemporary philosophical discussion. Metaphysi cians, process theologians, semanticists, theorists of knowledge, phenomenologists, and philosophers of mathematics will thus find in this book, it is hoped, helpful materials (...) and methods. The categoreal scheme of Whitehead's Process and Reality is discussed rather fully from a logical point of view in the first paper [I] in the light of the author's previous work on the logico-metaphysical theory of events. The clarification that results is thought to provide a new depth and precision to the problem of interpreting one of the most difficult books in the recent history of metaphysics and cosmol ogy. A detailed examination of some aspects of Hartshorne's recent Creative Synthesis and Philosophic Method is given in II. This book is perhaps the most significant work on process philosophy since Process and Reality itself, and its logical underpinnings thus merit a full critical discussion. (shrink)

We argue that thoughts are structures of concepts, and that concepts should be individuated by their origins, rather than in terms of their semantic or epistemic properties. Many features of cognition turn on the vehicles of content, thoughts, rather than on the nature of the contents they express. Originalism makes concepts available to explain, with no threat of circularity, puzzling cases concerning thought. In this paper, we mention Hesperus/Phosphorus puzzles, the Evans-Perry example of the ship seen through different windows, and (...) Mates cases, and we believe that there are many additional applications. (shrink)

Are fictional characters such as Sherlock Holmes real? What can fiction tell us about the nature of truth and reality? In this excellent introduction to the problem of fictionalism R. M. Sainsbury covers the following key topics: what is fiction? realism about fictional objects, including the arguments that fictional objects are real but non-existent; real but non-factual; real but non-concrete the relationship between fictional characters and non-actual worlds fictional entities as abstract artefacts fiction and intentionality and the problem of irrealism (...) fictionalism about possible worlds moral fictionalism. R. M. Sainsbury makes extensive use of examples from fiction, such as Sherlock Holmes, Anna Karenina and Madame Bovary and examines the work of philosophers who have made significant contributions to the topic, including Meinong, David Lewis, and Bas Van Fraassen. Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making _Fiction and Fictionalism_ ideal for those coming to the issue for the first time.

Scholars of Plato are divided between those who emphasize the literature of the dialogues and those who emphasize the argument of the dialogues, and between those who see a development in the thought of the dialogues and those who do not. In this important book Russell Dancy focuses on the arguments and defends a developmental picture. He explains the Theory of Forms of the Phaedo and Symposium as an outgrowth of the quest for definitions canvassed in the Socratic dialogues, by (...) constructing a Theory of Definition for the Socratic dialogues based on the refutations of definitions in those dialogues, and showing how that theory is mirrored in the Theory of Forms. His discussion, notable for both its clarity and its meticulous scholarship, ranges in detail over a number of Plato's early and middle dialogues, and will be of interest to readers in Plato studies and in ancient philosophy more generally.

In the early part of the paper, I attempt to explain a dispute between two parties who endorse the compositionality of language but disagree about its implications: Paul Horwich, and Jerry Fodor and Ernest Lepore. In the remainder of the paper, I challenge the thesis on which they are agreed, that compositionality can be taken for granted. I suggest that it is not clear what compositionality involves nor whether it obtains. I consider some kinds of apparent counterexamples, and compositionalist responses (...) to them in terms of covert indexicality and unspecific meanings. I argue that the last option is the best for most of the cases I consider. I conclude by stressing, as against Horwich and Fodor and Lepore, that the appropriate question concerns the extent to which compositionality obtains in a natural language, rather than whether it obtains or not, so that the answer is essentially messy, requiring detailed consideration of a wide range of examples.

This book is divided into three parts: in Part I, R. M. Hare offers a justification for the use of philosophy of language in the treatment of moral questions, together with an overview of his moral philosophy of ‘universal prescriptivism’. The second part, and the core of the book, consists of five chapters originally presented as a lecture series under the title ‘A Taxonomy of Ethical Theories’. Hare identifies descriptivism and non‐descriptivism as the two main positions in modern moral philosophy. (...) The former he divides into Naturalism and Intuitionism, and the latter into Emotivism and Rationalism. Hare argues that all forms of descriptivism tend to lead to Relativism because the truth conditions of moral statements are culturally variant. Of the positions discussed, only Hare's own position, a form of Rationalism, which he calls Universal Prescriptivism, meets all of the requirements that an adequate ethical theory should meet. Part III consists of Hare's previously published essay ‘Could Kant have been a Utilitarian?’ (Utilitas 5, 1993). Here, Hare puts forward the controversial thesis that Kant's moral philosophy is, in its basic principles, compatible with utilitarianism. (shrink)

The paper argues that intensional phenomena can be explained without appealing to "exotic" entities: one that don't exist, are merely possible, or are essentially abstract.

I had a strange dream, or half-waking vision, not long ago. I found myself at the top of a mountain in the mist, feeling very pleased with myself, not just for having climbed the mountain, but for having achieved my life's ambition, to find a way of answering moral questions rationally. But as I was preening myself on this achievement, the mist began to clear, and I saw that I was surrounded on the mountain top by the graves of all (...) those other philosophers, great and small, who had had the same ambition, and thought they had achieved it. And I have come to see, reflecting on my dream, that, ever since, the hard-working philosophical worms have been nibbling away at their systems and showing that the achievement was an illusion. True, their skeletons, indigestible to worms, remained, and were surprisingly similar to one another. But I was led to think again about what one can, and what one cannot, achieve in this direction.

Politics and religion certainly ride together throughout the Dune saga. Rationales were given to support twentieth century dictator ships, whose citizens were encouraged to see their leaders as infallible. In this way, politics in a totalitarian state resembled a religion, with a community of faithful followers and its own special theology to justify the dictator's authority. This chapter, draws parallels between the religious dimensions of politics in Frank Herbert's Dune novels and some philosophers’ views on tyranny and justice here on (...) Earth. Even in democratic countries, leaders still tend to think of themselves as in service to some higher, impersonal standard, like a set of principles, a tradition, a flag, or a constitution. Plato's readers have sometimes described the relation between the higher plane of reality of universals and the world of everyday experience in terms of the relation between heaven and earth in the Abrahamic religions.

Arrian's enthusiasm for Ptolemy's account of Alexander has often been echoed in modern times. With much justification it is generally agreed that Arrian's account of Alexander, through its reliance on the works of Ptolemy and Aristobulus, is our best and, on the whole, most reliable account of Alexander. Recent work, however, has illuminated Ptolemy's weaknesses, and we can no longer regard Ptolemy as utterly reliable in every important respect. His version of the Alexander story is centred on Alexander, therefore Alexander (...) is depicted out of the close context of the Macedonian court. It is only through the information preserved in other writers—traditionally, but undiscriminatingly, considered unreliable—that, for instance, the picture of Alexander's struggle with his Macedonian nobles has begun to emerge. And in matters of this kind Ptolemy's version is so much the court ‘official’ version that it cannot be regarded as trustworthy. (shrink)

In La filosofia dell’arte, Giovanni Gentile assigned a prominent new role to the sentiments. This change struck some critics as a major departure from the earlier, classic accounts of actual idealism, in which Gentile argued that thought and language comprise the entirety of reality. Sentiments do not fit cleanly into a theory so narrowly concerned with thought and thinking. Their introduction, runs the objection, only compounds certain existing ambiguities in Gentile’s conception of the relation between mind and world. This article (...) describes and criticizes Gentile’s attempts to integrate feeling into actual idealism. It is argued that the appearance of feeling in his mature theory does not undermine but instead clarifies his views on the relation between thought and the act of thinking. Yet it also shows the strain under which idealist language was being put by the late 1920s. Gentile’s attempts to lay out a comprehensive and phenomenologically accurate account of how thinkers actually experience... (shrink)

In this article I examine the metaphysical foundations of Guido de Ruggiero’s liberalism and ask what these can tell us about his changing view of Giovanni Gentile's actualism, which was such an influence on de Ruggiero before the First World War. I argue that de Ruggiero’s ‘actualism’ was never the same as Gentile’s, but was drawn from the same intellectual sources; that the actualist conception of free and self-conscious agency runs through both versions of the doctrine, though interpreted in different (...) ways; and finally that the contrasts between de Ruggiero’s and Gentile’s political allegiances result from something other than their differing interpretations of actualism, which serves, in the end, not so much as a theory as a set of basic principles, images and ideals that each philosopher tried to modify and match to the political circumstances in which he found himself.

Originally published in 1958. A study in the logical foundations of modern theoretical semantics, this book is concerned with notions of designation and consistency as well as denotation and truth. It presents several semantical theories, each of which with what were new concepts or treatments from the author. Talking at a time when semantical theory was gained great ground, this book also looks at the methodology of the sciences and the semantics of scientific language alongside analysis of meaning and expression. (...) It is influenced by the writings of Carnap, Church, Frege, Goodman, Quine, Russell and Tarski. (shrink)

Logic ought to guide our thinking. It is better, more rational, more intelligent to think logically than to think illogically. Illogical thought leads to bad judgment and error. In any case, if logic had no role to play as a guide to thought, why should we bother with it?The somewhat naïve opinions of the previous paragraph are subject to attack from many sides. It may be objected that an activity does not count as thinking at all unless it is at (...) least minimally logical, so logic is constitutive of thought rather than a guide to it. Or it may be objected that whereas logic describes a system of timeless relations between propositions, thinking is a dynamic process involving revisions, and so could not use a merely static guide. Or again the objection may be that there is no such thing as logic, only a whole variety of different logics, not all of which could possibly be good guides. (shrink)

This article discusses the definition of slavery as a status in society and a relation to an owner. an imaginary case in which utilitarian arguments could justify slavery. this case, just because it is highly unlikely to occur in the actual world, does not provide an argument against utilitarianism. if it did occur, slavery would be justified in this case, but that is no reason for abandoning our intuitive principle condemning slavery. the adoption of this principle has in the actual (...) world a good utilitarian justification. slavery is wrong because in the world of men as they are it will almost always cause misery.
