Where does consciousness come from and how does it work? Is it a purely biological thing? Where does the brain leave off and the mind begin? These questions, once viewed as ethereal and impossible to study empirically, are now being addressed by science in bold and startling new ways.In Consciousness, world-renowned neuropsychiatrist J. Allan Hobson presents a witty and introspective consideration of this mysterious concept, connecting it to specific areas of the brain and their chemical and physical states. Hobson guides (...) his readers through the various states of waking, dreaming, and nonconsciousness using the theories and data of neuroscience, psychiatry, and neurophysiology. Although his ideas are based in science, his imaginative approach keeps us in touch with the mysterious and seductive nature of his subject.Richly woven, with references to literature, philosophy, and the author's personal experiences, Consciousness is a delightful and compact introduction to a concept central to the human experience.

Given classical (2 valued) structures and and a homomorphism h of onto , it is shown how to construct a (non-degenerate) 3-valued counterpart of . Classical sentences that are true in are non-false in . Applications to number theory and type theory (with axiom of infinity) produce finite 3-valued models in which all classically true sentences of these theories are non-false. Connections to relevant logic give absolute consistency proofs for versions of these theories formulated in relevant logic (the proof for (...) number theory was obtained earlier by R. K. Meyer and suggested the present abstract development). (shrink)

An important role of the philosopher is to critically reflect on what is often taken for granted, using the tools of argument and analysis. This article engages with six different papers that offer critical reflections on conventional concepts and beliefs in bioethics regarding informed consent, continuous deep sedation, traditional moral theories underlying bioethical thinking, the definition of mental disease, and codes of ethics for particular medical specialties.

Prominent philosophers have argued that contradictions contain either too much or too little information to be useful. We dispute this with what we call the “Paradox of the Two Firefighters.” Suppose you are awakened in your hotel room by a fire alarm. You open the door. You see three possible ways out: left, right, straight ahead. You see two firefighters. One says there is exactly one safe route and it is to your left. The other says there is exactly one (...) safe route and it is to your right. While the two firemen are giving you contradictory information, they are also both giving you the perhaps useful information that there is a safe way out and it is not straight ahead. We give two analyses. The first uses the “Opinion Tetrahedron,” introduced by Dunn as a generalization of Audun Jøsang’s “Opinion Triangle.” The Opinion Tetrahedron in effect embeds the values of the “Belnap-Dunn 4-valued Logic” into a context of subjective probability generalized to allow for degrees of belief, disbelief, and two kinds of uncertainty—that in which the reasoner has too little information and that in which the reasoner has too much information. Jøsang had only a single value for uncertainty. We also present an alternative solution, again based on subjective probability but of a more standard type. This solution builds upon “linear opinion pooling.” Kiefer had already developed apparatus for assessing risk using expert opinion, and this influences the second solution. Finally, we discuss how these solutions might apply to “Big Data” and the World Wide Web. (shrink)

This paper aims to establish that Sorites reasoning, a fundamental part of Parfit's work, is more destructive that he intends. I establish the form that Parfit's arguments take and then substitute premises whose acceptability to Parfit I show. The new argument demonstrates an eliminativism or immaterialism concerning persons which Parfit must find repugnant.

Cheating and deception are terms often used but rarely defined. They summon up unpleasant connotations; even those deeply involved with cheating and deception rationalize why they have been driven to it. Particularly for Americans and much of Western civilization, official cheating, government duplicity, cheating as policy, and conscious, contrived deception, are all unacceptable except as a last resort in response to threat of extinction. As a distasteful tool, deception is rarely used to achieve national interests, unless in relation to the (...) deployment of military force. As an area of study, it has by and large been ignored.Intrigued by attitudes toward cheating and deception, the authors decided to analyze its roots, structure, and process. They asked fundamental questions: are there categories of deception, general steps in the process of deception, and ways to evaluate its results across time and in different modes? The book that results is a typology of kinds of deception, beginning with military deception, but extending into other categories and stages.In his introduction to this new edition, Bell outlines how the book came to be written, describes the mixed emotions toward the subject displayed by govenmental and nongovernmental funding sources, and speculates about its critical and commercial reception. He discusses widespread new interest in the subject, the research that has been undertaken since this book was first published, and its limitations.This book provides a general overview of this complex subject, creating a framework for analysis of specific instances of cheating or deception. It will be of particular interest to political scientists, those interested in military affairs and strategy, and psychologists. The general reader will find the book written with a light touch, drawing examples of cheating and deception in the pursuit of love and money. The specialist reader will be intrigued by its broad-ranging examples drawn from policy and politics, wars and rumors of wars. (shrink)

First published in 1952, British Empirical Philosophers is a comprehensive picture of one of the most important movements in the history of philosophic thought. In his introduction, Professor A. J. Ayer distinguishes the main problems of empiricism and gives a critical account of the ways in which the philosophers whose writings are included in this volume attempted to solve them. Editors Ayer and Raymond Winch bring together an authoritative abridgement of John Locke’s Essay Concerning Human Understanding ; Bishop George Berkeley’s (...) Principles of Human Knowledge ; almost the entire first book of David Hume’s Treatise Concerning Human Nature ; and extracts from Thomas Reid’s Essay on the Intellectual Powers of Man and John Stuart Mill’s Examination of Sir William Hamilton’s Philosophy.

Isaac Newton's closest approach to a system of the world in the critical period 1681–84 is provided in a set of untitled propositions concerning comets. They drastically revise his position maintained against Flamsteed in 1681 and may signal his adoption of a single comet solution for the appearances of 1680/1. Points of agreement and difference with the key pre-Principia texts of 1684–85 are analysed. He shows substantial control of the phenomena of tails which change very little in mechanical detail throughout (...) his subsequent work. An emerging theory of gravitation brings planets, their satellites, and comets under the same laws of motion, yet retains a celestial vortex and includes a singular proposition in lieu of the usual formulation of Keplers area law. The analysis raises questions on a number of issues of recent Newtonian scholarship ranging from his achievement following his correspondence with Robert Hooke in 1679 to his veneration of the wisdom of the ancients.

ABSTRACT On 19 July 2019, Agnes Heller died whilst swimming in Lake Balaton outside Budapest. With her passing, the culture of humanity lost one of its most remarkable representatives. So too, contemporary critique lost a philosophical sensibility that is, today, within the neoliberal university, increasingly rare. It is this philosophical sensibility with which this essay is concerned. Through a critical reconstruction of Heller’s reading of three key figures from the philosophical tradition (Marx, Pascal and Kierkegaard), this essay both charts the (...) changes and continuities in Heller’s philosophy of concrete subjectivity and makes a case for its continuing relevance to the cultural project of philosophy.

Cognitive science-informed approaches have gained considerable influence in education in the UK and internationally, but not much is known about how teachers perceive cognitive science-informed strategies or enact them within the contexts of their everyday classrooms. In this paper, we discuss the perceptions and experiences of cognitive science-informed strategies of 13 teachers in England. The paper critically explores how the teachers understood and used cognitive science-informed strategies in their teaching, their views of the benefits and challenges for different subjects and (...) groups of learners, and their reflections on supporting factors and barriers for adopting the strategies in their schools. The teachers’ accounts illustrate some of the many complexities of adopting cognitive science-informed approaches in real-life educational settings. Drawing on their narratives, the paper emphasises the importance of acknowledging different contextual dimensions and the dynamic interactions between them to understand when and how teachers enact cognitive science-informed approaches in their classrooms.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.
