Epistemic Principles: A Primer of the Theory of Knowledge presents a compact account of the basic principles of the theory of knowledge. In doing this, Nicholas Rescher aims to fill the current gap in contemporary philosophical theory of knowledge with a comprehensive analysis of epistemological fundamentals. The book is not a mere inventory of such rules and principles, but rather interweaves them into a continuous exposition of basic issues. Written at a user-friendly and accessible level, Epistemic Principles is an essential addition for both advanced undergraduate and graduate courses in epistemology.

It is with great pleasure that we are presenting to the community the second edition of this extraordinary handbook. It has been over 15 years since the publication of the first edition and there have been great changes in the landscape of philosophical logic since then. The first edition has proved invaluable to generations of students and researchers in formal philosophy and language, as well as to consumers of logic in many applied areas. The main logic article in the Encyclopaedia Britannica 1999 has described the first edition as 'the best starting point for exploring any of the topics in logic'. We are confident that the second edition will prove to be just as good The first edition was the second handbook published for the logic commu nity. It followed the North Holland one volume Handbook of Mathematical Logic, published in 1977, edited by the late Jon Barwise. The four volume Handbook of Philosophical Logic, published 1983-1989 came at a fortunate temporal junction at the evolution of logic. This was the time when logic was gaining ground in computer science and artificial intelligence circles. These areas were under increasing commercial pressure to provide devices which help and/or replace the human in his daily activity. This pressure required the use of logic in the modelling of human activity and organisa tion on the one hand and to provide the theoretical basis for the computer program constructs on the other."

This book addresses the logical aspects of the foundations of scientific theories. Even though the relevance of formal methods in the study of scientific theories is now widely recognized and regaining prominence, the issues covered here are still not generally discussed in philosophy of science. The authors focus mainly on the role played by the underlying formal apparatuses employed in the construction of the models of scientific theories, relating the discussion with the so-called semantic approach to scientific theories. The book describes the role played by this metamathematical framework in three main aspects: considerations of formal languages employed to axiomatize scientific theories, the role of the axiomatic method itself, and the way set-theoretical structures, which play the role of the models of theories, are developed. The authors also discuss the differences and philosophical relevance of the two basic ways of aximoatizing a scientific theory, namely Patrick Suppes' set theoretical predicates and the "da Costa and Chuaqui" approach. This book engages with important discussions of the nature of scientific theories and will be a useful resource for researchers and upper-level students working in philosophy of science.

Originally published in 1973, this book shows that methods developed for the semantics of systems of formal logic can be successfully applied to problems about the semantics of natural languages; and, moreover, that such methods can take account of features of natural language which have often been thought incapable of formal treatment, such as vagueness, context dependence and metaphorical meaning. Parts 1 and 2 set out a class of formal languages and their semantics. Parts 3 and 4 show that these formal languages are rich enought to be used in the precise description of natural languages. Appendices describe some of the concepts discussed in the text.

From Concept to Objectivity uncovers the nature and authority of conceptual determination by critically thinking through neglected arguments in Hegel's Science of Logic pivotal for understanding reason and its role in philosophy. Winfield clarifies the logical problems of presuppositionlessness and determinacy that prepare the way for conceiving the concept, examines how universality, particularity, and individuality are determined, investigates how judgment and syllogism are exhaustively differentiated, and, on that basis, explores how objectivity can be categorized without casting thought in irrevocable opposition to reality. Winfield's book will be of interest to readers of Hegel as well as anyone wondering how thought can be objective.

This book advances a reading of Wittgenstein's Tractatus that moves beyond the main interpretative options of the New Wittgenstein debate. It covers Wittgenstein's approach to language and logic, as well as other areas unduly neglected in the literature, such as his treatment of metaphysics, the natural sciences and value. Tejedor re-contextualises Wittgenstein's thinking in these areas, plotting its evolution in his diaries, correspondence and pre-Tractatus texts, and developing a fuller picture of its intellectual background. This broadening of the angle of view is central to the interpretative strategy of her book: only by looking at the Tractatus in this richer light can we address the fundamental questions posed by the New Wittgenstein debate - questions concerning the method of the Tractatus, its approach to nonsense and the continuity in Wittgenstein's philosophy. Wittgenstein's early work remains insightful, thought-inspiring and relevant to contemporary philosophy of language and science, metaphysics and ethics. Tejedor's ground-breaking work ultimately conveys a surprisingly positive message concerning the power for ethical transformation that philosophy can have, when it is understood as an activity aimed at increasing conceptual clarification and awareness.

Originally published in 1966 On the Syllogism and Other Logical Writings assembles for the first time the five celebrated memoirs of Augustus De Morgan on the syllogism. These are collected together with the more condensed accounts of his researches given in his Syllabus of a Proposed System of Logic an article on Logic contributed to the English Cyclopaedia. De Morgan was among the most distinguished of nineteenth century British mathematicians but is chiefly remembered today as one of the founders of modern mathematical logic. His writings on this subject have been little read, however since apart from his Formal Logic, they lie buried for the most part in inaccessible periodicals. De Morgan's own later amendments are inserted in the text and the editorial introduction gives a summary of the whole and traces in some detail the course of the once-famous feud with Sir William Hamilton of Edinburgh.

Bounded Thinking offers a new account of the virtues of limitation management: intellectual virtues of adapting to the fact that we cannot solve many problems that we can easily describe. Adam Morton argues that we do give one another guidance on managing our limitations, but that this has to be in terms of virtues and not of rules, and in terms of success-knowledge and accomplishment-rather than rationality. He establishes a taxonomy of intellectual virtues, which includes 'paradoxical virtues' that sound like vices, such as the virtue of ignoring evidence and the virtue of not thinking too hard. There are also virtues of not planning ahead, in that some forms of such planning require present knowledge of one's future knowledge that is arguably impossible. A person's best response to many problems depends not on the most rationally promising solution to solving them but on the most likely route to success given the profile of intellectual virtues that the person has and lacks. Morton illustrates his argument with discussions of several paradoxes and conundra. He closes the book with a discussion of intelligence and rationality, and argues that both have very limited usefulness in the evaluation of who will make progress on which problems.

The twentieth century witnessed the birth of analytic philosophy. This volume covers some of its key movements and philosophers, including Frege and Wittgenstein's Tractatus.

AS Critical Thinking for AQA is the definitive textbook for students of the current AQA Advanced Subsidiary Level syllabus. Structured very closely around the AQA specification, it covers the two units of the AS level in an exceptionally clear and student-friendly style. The chapters are helpfully subdivided into short digestible passages, and include: intended learning objectives at the beginning of each chapter student exercises at the end of each section with a 'stretching activity' for more advanced learners exam orientated questions key point summaries at the end of each section cross references. In line with the AQA specification, there is a heavy emphasis on more imaginative forms of source material, for example, music, film, artwork, historical documents, adverts, moral dilemmas and scientific debates, as a means of illustrating key points. A great deal of emphasis is also placed on 'live' or 'real' arguments, taking topical examples from the world of science, politics, entertainment and sport. The book is accompanied by a companion website with extensive resources for both instructors and students.

This volume identifies and analyses English words and expressions that are crucial for an adequate reconstruction of argumentative discourse. It provides the analyst of argumentative discussions and texts with a systematic set of instruments for giving a well founded analysis which results in an analytic overview of the elements that are relevant for the evaluation of the argumentation. In the book a systematic connection is made between linguistic insights into the characteristics of argumentative discourse and insights from argumentation theory into the resolution of differences of opinion by means of argumentation.

This book offers readers a collection of 50 short chapter entries on topics in the philosophy of language. Each entry addresses a paradox, a longstanding puzzle, or a major theme that has emerged in the field from the last 150 years, tracing overlap with issues in philosophy of mind, cognitive science, ethics, political philosophy, and literature. Each of the 50 entries is written as a piece that can stand on its own, though useful connections to other entries are mentioned throughout the text. Readers can open the book and start with almost any of the entries, following themes of greatest interest to them. Each entry includes recommendations for further reading on the topic. Philosophy of Language: 50 Puzzles, Paradoxes, and Thought Experiments is useful as a standalone textbook, or can be supplemented by additional readings that instructors choose. The accessible style makes it suitable for introductory level through intermediate undergraduate courses, as well as for independent learners, or even as a reference for more advanced students and researchers. Key Features: Uses a problem-centered approach to philosophy of language (rather than author- or theory-centered) making the text more inviting to first-time students of the subject. Offers stand-alone chapters, allowing students to quickly understand an issue and giving instructors flexibility in assigning readings to match the themes of the course. Provides up-to-date recommended readings at the end of each chapter, or about 500 sources in total, amounting to an extensive review of the literature on each topic.

The author extensively details, analyses and compares key concepts and strategies of fictional worlds theory: a theory which has, over recent years, developed rather rapidly and is connected with leading scholars in the area of literary studies, such as Lubomir Dolezel, Umberto Eco, Thomas Pavel, Ruth Ronen, and Marie-Laure Ryan. The book focuses on theoretical suggestions from which the fictional worlds theory borrows its main ideas, that is, logic, semantics, and linguistics. It also examines areas of literary theoretical investigation, in which the fictional world theory has proven itself to be a significant tool for conducting more detailed research, namely intertextuality, fictional and historical narration.

Patrick Aidan Heelan's The Observable offers the reader a completely articulated development of his 1965 philosophy of quantum physics, Quantum Mechanics and Objectivity. In this previously unpublished study dating back more than a half a century, Heelan brings his background as both a physicist and a philosopher to his reflections on Werner Heisenberg's physical philosophy. Including considerably broader connections to the contributions of Niels Bohr, Wolfgang Pauli, and Albert Einstein, this study also reflects Heelan's experience in Eugene Wigner's laboratory at Princeton along with his reflections on working with Erwin Schroedinger dating from Heelan's years at the Institute for Advanced Cosmology in Dublin. A contribution to continental philosophy of science, the phenomenological and hermeneutic resources applied in this book to the physical and ontological paradoxes of quantum physics, especially in connection with laboratory science and measurement, theory and model making, will enrich students of the history of science as well as those interested in different approaches to the historiography of science. University courses in the philosophy of physics will find this book indispensable as a resource and invaluable for courses in the history of science.

In "God, Mind and Logical Space" Istvan Aranyosi takes the reader on a journey for the mind by revisiting the fundamental questions and the everlasting debates in philosophy of religion, ontology, and the philosophy of mind. The first part deals with issues in ontology, and the author puts forward a radical view according to which all thinkable objects and states of affairs have an equal claim to existence in a way that renders existence a relative notion. In the second part another radical view is argued for, according to which some objects and states of affairs that do not exist in our world are nevertheless present in our surroundings by being real in their consequences. The final part argues that the only way to prove the existence of God is to accept a view called Logical Pantheism, according to which God is identical to Logical Space.

What are reason and rationality? How significant are recent postmodernist and neuroscientific challenges to these longheld notions? Should we abandon a belief in reason and an adherence to rationality? Or can reason and rationality be reformulated and reframed? And what does politics have to do with how we think about reason and why we act more or less rationally? The Politics of Rationality differs from other books with "reason" or "rationality" due to its historical, political, depth-psychological, and multidisciplinary approach to understanding reason through history. Charles P. Webel eloquently clarifies the links among ideas, their creators, the relevant mental processes, and the political cultures within which such important concepts as reasons and rationality take hold. He demonstrates how reason and rationality/irrationality have become what they mean for us today and proposes a way to rethink reason and rationality in light of the withering critiques leveled against them. In doing so, he presents a "history of reason and rationality" by examining the intellectual and political contexts of four representative theorists of reason and rationality-- Plato, Machiavelli, Kant, and Weber-and by addressing contemporary challenges posed by postmodernism, depth psychology, and neurophilosophy.

This book presents an edition of the Questiones super libro De Animalibus Aristotelis, a work by one of the greatest philosophers and physicians of the 13th century, Peter of Spain (later Pope John XXI, 1205-1277). He took as the basis for his work the translation from the Arabic made in Toledo around 1220 by Michael Scotus which included three important Aristotelian treatises. Preceding the critical edition, Dr Navarro offers an introduction to the person and works of Peter of Spain, the intellectual context of the 13th century characterized by Scholasticism and an Aristotelian Renaissance, and a short analysis of the linguistics and form of the Questiones. She also analyses the sources on which Peter drew, Greco-Latin, Arabo-Jewish and, of course, late antique and medieval treatises, showing that the text was not exclusively zoological in nature, but discusses important medical and philosophical topics, illustrating his extensive knowledge of both the Aristotelian corpus and 13th-century medicine. The text (divided into XIX books) is not a mere commentary about animals, but rather, as the title shows, a collection of questions in the Salernitan manner, the use of which was considered most appropriate for analysis and communication in the medieval scientific community to which Peter of Spain belonged. Alongside methodological and zoological problems, Peter of Spain discusses important questions disputed among the scholars of the period, including the location, hierarchy, motion, function and parts of the principal organs, the five senses, and many other medical issues such as reproduction, illnesses, or growth. Finally Dr Navarro includes a glossary that contains proper names (mainly those of the authorities and sources quoted by Petrus Hispanus), animal names (and their parts and substances), and the names of plants, metals, and the like.

Paradoxes from A to Z, Third edition is the essential guide to paradoxes, and takes the reader on a lively tour of puzzles that have taxed thinkers from Zeno to Galileo, and Lewis Carroll to Bertrand Russell. Michael Clark uncovers an array of conundrums, such as Achilles and the Tortoise, Theseus' Ship, and the Prisoner's Dilemma, taking in subjects as diverse as knowledge, science, art and politics. Clark discusses each paradox in non-technical terms, considering its significance and looking at likely solutions. This third edition is revised throughout, and adds nine new paradoxes that have important bearings in areas such as law, logic, ethics and probability. Paradoxes from A to Z, Third edition is an ideal starting point for those interested not just in philosophical puzzles and conundrums, but anyone seeking to hone their thinking skills.

Truth Be Told explains how truth and falsity result from relations that sentences have to the contexts in which they occur and the circumstances at which they are evaluated. It offers a precise conception of truth and a clear diagnosis of the Liar and Grelling paradoxes. Currently, semantic theory employs generalized quantifiers as the extensions of noun phrases in explanations of the composition of truth-values. Generalized quantifiers are direct descendants of the second-level functions to truth-values that Gottlob Frege considered to be the referents of his unrestricted quantifiers. During the past fifty years, Frege's original quantifier referents have been revised and generalized with the result that now every noun phrase, of any type, has a generalized quantifier as its extension. This evolution of noun-phrase extensions from Frege's referents has retained two of the original theory's flaws. First, generalized quantifiers inherit a troublesome intrusion of predicate extensions. Second, the senses of names and deictic terms are still not identified, with the result that their extensions are not sharply distinguished from their referents. Truth Be Told frees semantic theory from these Fregean flaws. Its theory of sense, quantity, and extension yields an intuitive composition of sentence truth-values and secures an accurate understanding of truth. Its final chapter applies the theory in a diagnosis of the Liar and Grelling paradoxes that is immune to the notorious revenge paradoxes. Truth Be Told can be used for courses in philosophy of language, semantics, and the foundations of logic.

This volume responds to the growing interest in finding explanations for why moral claims may lose their validity based on what they ask of their addressees. Two main ideas relate to that question: the moral demandingness objection and the principle "ought implies can." Though both of these ideas can be understood to provide an answer to the same question, they have usually been discussed separately in the philosophical literature. The aim of this collection is to provide a focused and comprehensive discussion of these two ideas and the ways in which they relate to one another, and to take a closer look at the consequences for the limits of moral normativity in general. Chapters engage with contemporary discussions surrounding "ought implies can" as well as current debates on moral demandingness, and argue that applying the moral demandingness objection to the entire range of normative ethical theories also calls for an analysis of its (metaethical) presuppositions. The contributions to this volume are at the leading edge of ethical theory, and have implications for moral theorists, philosophers of action, and those working in metaethics, theoretical ethics and applied ethics.

The subject of the book is a reconsideration of the internalistic model of composition of the Platonic type, more radical than traditional, post-Aristotelian externalistic compositionism, and its application in the field of the ontology of quantum theory. At the centre of quantum ontology is nonseparability. Quantum wholes are atemporal wholes governed by internalistic logic and they are primitive, global physical entities, requiring an extreme relativization of the fundamental notions of mechanics. That ensures quantum theory to be fully consistent with the relativistic causal structure, without any spacelike nonlocality and time asymmetry, and makes the quantum blockworld ontology inevitable. It seems that the more internally relativized physics is, the more Platonic it becomes.
