Silly rabbit Your argument is ill-founded.

Have you read (or stumbled into) one too many irrational online debates? Ali Almossawi certainly had, so he wrote An Illustrated Book of Bad Arguments This handy guide is here to bring the internet age a much-needed dose of old-school logic (really old-school, a la Aristotle).

Here are cogent explanations of the straw man fallacy, the slippery slope argument, the ad hominem attack, and other common attempts at reasoning that actually fall short plus a beautifully drawn menagerie of animals who (adorably) commit every logical faux pas. Rabbit thinks a strange light in the sky must be a UFO because no one can prove otherwise (the appeal to ignorance). And Lion doesn t believe that gas emissions harm the planet because, if that were true, he wouldn t like the result (the argument from consequences).

Once you learn to recognize these abuses of reason, they start to crop up everywhere from congressional debate to YouTube comments which makes this geek-chic book a must for anyone in the habit of holding opinions. It s the antidote to fuzzy thinking, with furry animals "

A COMPANION TO WITTGENSTEIN The most comprehensive survey of Wittgenstein's thought yet compiled, this volume of fifty newly commissioned essays by leading interpreters of his philosophy is a keynote addition to the Blackwell Companions to Philosophy series. Full of penetrating insights into the life and work of the most important philosopher of the twentieth century, the collection explores the full range of Wittgenstein's contribution to philosophy. It includes essays on his intellectual development, his work in logic and mathematics, philosophy of language, philosophy of mind and action, epistemology, ethics, philosophy of religion, and much else. As well as examining Wittgenstein's contribution to human understanding in detail, the Companion features vital contextual analysis that traces the relationship between his ideas and those of other philosophers and schools of thought, including the Aristotelian and continental philosophical traditions. Authors also address prominent themes that remain current in today's philosophical debates, explaining Wittgenstein's continuing legacy alongside his historical significance. Essential reading for scholars of philosophy at all levels, A Companion to Wittgenstein combines engaging commentary with unrivaled academic authority.

Logic Works is a critical and extensive introduction to logic. It asks questions about why systems of logic are as they are, how they relate to ordinary language and ordinary reasoning, and what alternatives there might be to classical logical doctrines. The book covers classical first-order logic and alternatives, including intuitionistic, free, and many-valued logic. It also considers how logical analysis can be applied to carefully represent the reasoning employed in academic and scientific work, better understand that reasoning, and identify its hidden premises. Aiming to be as much a reference work and handbook for further, independent study as a course text, it covers more material than is typically covered in an introductory course. It also covers this material at greater length and in more depth with the purpose of making it accessible to those with no prior training in logic or formal systems. Online support material includes a detailed student solutions manual with a running commentary on all starred exercises, and a set of editable slide presentations for course lectures. Key Features Introduces an unusually broad range of topics, allowing instructors to craft courses to meet a range of various objectives Adopts a critical attitude to certain classical doctrines, exposing students to alternative ways to answer philosophical questions about logic Carefully considers the ways natural language both resists and lends itself to formalization Makes objectual semantics for quantified logic easy, with an incremental, rule-governed approach assisted by numerous simple exercises Makes important metatheoretical results accessible to introductory students through a discursive presentation of those results and by using simple case studies

This book offers an array of important perspectives on Kant and nonconceptualism from some of the leading scholars in current Kant studies. As well as discussing the various arguments surrounding Kantian nonconceptualism, the book provides broad insight into the theory of perception, philosophy of mind, philosophy of mathematics, epistemology, and aesthetics. His idealism aside, Kantian nonconceptualism is the most topical contemporary issue in Kant's theoretical philosophy. In this collection of specially commissioned essays, major players in the current debate, including Robert Hanna and Lucy Allais, engage with each other and with the broader literature in the field addressing all the important aspects of Kantian nonconceptualism. Among other topics, the authors analyse the notion of intuition and the conditions of its generation, Kant's theory of space, including his pre-Critical view of space, the relation between nonconceptualism and the Transcendental Deduction, and various challenges to both conceptualist and nonconceptualist interpretations of Kant. Two further chapters explore a prominent Hegelian conceptualist reading of Kant and Kant's nonconceptualist position in the Third Critique. The volume also contains a helpful survey of the recent literature on Kant and nonconceptual content. Kantian Nonconceptualism provides a comprehensive overview of recent perspectives on Kant and nonconceptual content, and will be a key resource for Kant scholars and philosophers interested in the topic of nonconceptualism.

According to Bayesian epistemology, rational learning from experience is consistent learning, that is learning should incorporate new information consistently into one's old system of beliefs. Simon M. Huttegger argues that this core idea can be transferred to situations where the learner's informational inputs are much more limited than Bayesianism assumes, thereby significantly expanding the reach of a Bayesian type of epistemology. What results from this is a unified account of probabilistic learning in the tradition of Richard Jeffrey's 'radical probabilism'. Along the way, Huttegger addresses a number of debates in epistemology and the philosophy of science, including the status of prior probabilities, whether Bayes' rule is the only legitimate form of learning from experience, and whether rational agents can have sustained disagreements. His book will be of interest to students and scholars of epistemology, of game and decision theory, and of cognitive, economic, and computer sciences.

The Concept of Logical Consequence is a critical evaluation of the model-theoretic and proof-theoretic characterizations of logical consequence that proceeds from Alfred Tarski's characterization of the informal concept of logical consequence. This study evaluates and expands upon ideas set forth in Tarski's 1936 article on logical consequence, and appeals to his 1935 article on truth. Classical logic, as well as extensions and deviations are considered. Issues in the philosophy of logic such as the nature of logical constants, the philosophical significance of completeness, and the metaphysical and epistemological implications of logic are discussed in the context of the examination of the concept of logical consequence.

""Thinking about Logic"" is an accessible and thought-provoking collection of classic articles in the philosophy of logic. An ideal companion to any formal logic course or textbook, this volume illuminates how logic relates to perennial philosophical issues about knowledge, meaning, rationality, and reality. The editors have selected each essay for its brevity, clarity, and impact and have included insightful introductions and discussion questions. The puzzles raised will help readers acquire a more thorough understanding of fundamental logic concepts and a firmer command of the connections between formal logic and other areas of philosophical study: epistemology, philosophy of language, philosophy of science, and metaphysics.

Newton's bucket, Einstein's elevator, SchrAdinger's cat a " these are some of the best-known examples of thought experiments in the natural sciences. But what function do these experiments perform? Are they really experiments at all? Can they help us gain a greater understanding of the natural world? How is it possible that we can learn new things just by thinking?

In this revised and updated new edition of his classic text The Laboratory of the Mind, James Robert Brown continues to defend apriorism in the physical world. This edition features two new chapters, one on a oecounter thought experimentsa and another on the development of inertial motion. With plenty of illustrations and updated coverage of the debate between Platonic rationalism and classic empiricism, this is a lively and engaging contribution to the field of philosophy of science.

First published in 1971, Professor Putnam's essay concerns itself with the ontological problem in the philosophy of logic and mathematics - that is, the issue of whether the abstract entities spoken of in logic and mathematics really exist. He also deals with the question of whether or not reference to these abstract entities is really indispensible in logic and whether it is necessary in physical science in general.

This one-volume encyclopedia of logic introduces the central concepts of the field in a series of brief, non-technical, cross-referenced dictionary entries. The 352 alphabetically arranged entries give a clear, basic introduction to a very broad range of logical topics. Entries can be found on deductive systems, such as propositional logic, modal logic, deontic logic, temporal logic, set theory, many-valued logic, mereology, and paraconsistent logic. Similarly, there are entries on topics relating to those previously mentioned such as negation, conditionals, truth tables, and proofs. Historical periods and figures are also covered, including ancient logic, medieval logic, Buddhist logic, Aristotle, Ockham, Boole, Frege, Russell, Goedel, and Quine. There are even entries relating logic to other areas and topics, like biology, computers, ethics, gender, God, psychology, metaphysics, abstract entities, algorithms, the ad hominem fallacy, inductive logic, informal logic, the liar paradox, metalogic, philosophy of logic, and software for learning logic. In addition to the dictionary, there is a substantial chronology listing the main events in the history of logic, an introduction that sketches the central ideas of logic and how it has evolved into what it is today, and an extensive bibliography of related readings. This book is not only useful for specialists but also understandable to students and other beginners in the field.

Timothy Smiley has made ground-breaking contributions to modal logic, free logic, multiple-conclusion logic, and plural logic. He has illuminated Aristotlea (TM)s syllogistic, the ideas of logical form and consequence, and the distinction between assertion and rejection, and has worked to debunk the theory of descriptions. This volume brings together new articles by an international roster of leading logicians and philosophers in order to honour Smileya (TM)s work. Their essays will be of significant interest to those working across the logical spectruma "in philosophy of language, philosophical and mathematical logic, and philosophy of mathematics.

The present volume has its origin in a meeting of philosophers, linguists and cognitive scientists that was held at Umea University, Sweden, September 24-26, 1993. The meeting was organized by the Department of Philosophy in co-opersation with the Department of Linguistics, and it was called UmLLI-93, the Umea Colloquium on Dynamic Approaches in Logic, Language and Information. The papers included here fall into three broad categories. In the first part of the book, Action, are collected papers that concern the formal theory of action, the logic of norms, and the theory of rational decision. The papers in the second part, Belief Change, concern the theory of belief dynamics in the tradition of Alchourron, Gardenfors and Makinson. The third part, Cognition, concerns abstract questions about knowledge and truth as well as more concrete questions about the usefulness and tractability of various graphic representations of information.

The first edition, published by Acumen in 2000, became a prescribed textbook on modal logic courses. The second edition has been fully revised in response to readers' suggestions, including two new chapters on conditional logic, which was not covered in the first edition. "Modal Logics and Philosophy" is a fully comprehensive introduction to modal logics and their application suitable for course use. Unlike most modal logic textbooks, which are both forbidding mathematically and short on philosophical discussion, "Modal Logics and Philosophy" places its emphasis firmly on showing how useful modal logic can be as a tool for formal philosophical analysis. In part 1 of the book, the reader is introduced to some standard systems of modal logic and encouraged through a series of exercises to become proficient in manipulating these logics. The emphasis is on possible world semantics for modal logics and the semantic emphasis is carried into the formal method, Jeffrey-style truth-trees. Standard truth-trees are extended in a simple and transparent way to take possible worlds into account. Part 2 systematically explores the applications of modal logic to philosophical issues such as truth, time, processes, knowledge and belief, obligation and permission.

First Published in 1964, Studies in Metaphilosophy presents and develop the hypothesis about the nature of metaphysical theories. Each study is a fresh attempt to improve our understanding of what a philosophical theory is and what its supporting arguments come to. Author argues that philosophical theories are nothing more substantial than linguistic chimeras and has the important function of pointing up the need for the examination of the whole subject. The volume discusses important themes like concept analysis, systematic doubt, the method of deduction from fact, logical necessitation, the nature of philosophical analysis, the nature of value, the metaphysical concept of space, Moore and philosophical analysis, the hidden structure of philosophical theories, and the relevance of psychoanalysis to philosophy. This volume will be an essential source for scholars and researchers of philosophy, logic, and metaphysics.

This informative book is a necessary companion for anyone seeking to uncover the secret of successful persuasion: to organize, construct, and communicate arguments. It is at once comprehensive and accessible, an authoritative guide to logical thinking and effective communication. First, the text defines the nature and uses of argument, explaining how to read argument carefully. Such analysis then requires the student to reconstruct arguments in his or her own words. Finally, the reader is taught how to create a critical, reasoned response, thus constructing his or her own argument. To increase its accessibility and expand its range of application, "Critical Inquiry" uses (in addition to textual examples) advertisements from print media as "texts" for applying its principles to subjects outside the traditional mode of academic presentation. Throughout, carefully selected reading questions and exercises pace the reader and ensure that the material is securely grasped and successfully applied.

The main purpose of this work is to provide an English translation of and commentary on a recently published Arabic text dealing with con ditional propositions and syllogisms. The text is that of A vicenna (Abu represents his views on the subject as they were held throughout his life.

Real Essentialism presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like - can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. Real Essentialism reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

This volume is a collection of papers presented at the 2007 colloquium on new perspectives on games and interaction at the Royal Dutch Academy of Sciences in Amsterdam. The purpose of the colloquium was to clarify the uses of the concepts of game theory, and to identify promising new directions. This important collection testifies to the growing importance of game theory as a tool to capture the concepts of strategy, interaction, argumentation, communication, cooperation and competition. Also, it provides evidence for the richness of game theory and for its impressive and growing application.

Naturalism, Reference, and Ontology is a collection of twelve original essays honoring Roger F. Gibson, who has been a leading proponent and defender of W. V. Quine's philosophy for nearly thirty years. The essays address a wide range of topics, including normativity and naturalized epistemology, holism, consciousness, the philosophy of logic, perception, value theory, and the arts. The contributors are an international group of prominent philosophers as well as rising scholars including: Robert Barrett, Lars Bergstrom, Richard Creath, David Henderson, Terence Horgan, Ernest Lepore, Pete Mandik, Alex Orenstein, Kenneth Shockley, J. Robert Thompson, Josefa Toribio, Joseph Ullian, Josh Weisberg, and Chase B. Wrenn.

The topic of vagueness re-emerged in the twentieth century from relative obscurity. It deals with the phenomenon in natural language that manifests itself in apparent semantic indeterminacy - the indeterminacy, for example, that arises when asked to draw the line between the tall and non-tall, or the drunk and the sober. An associated paradox emphasises the challenging nature of the phenomenon, presenting one of the most resilient paradoxes of logic. The apparent threat posed for orthodox theories of the semantics and logic of natural language has become the focus of intense philosophical scrutiny amongst philosophers and non-philosophers alike. Vagueness, Logic and Ontology explores various responses to the philosophical problems generated by vagueness and its associated paradox - the sorites paradox. Hyde argues that the theoretical space in which vagueness is sometimes ontologically grounded and modelled by a truth-functional logic affords a coherent response to the problems posed by vagueness. Showing how the concept of vagueness can be applied to the world, Hyde's ontological account proposes a substantial revision of orthodox semantics, metaphysics and logic. This book will be of particular interest to readers in philosophy, linguistics, cognitive science and geographic information systems.

This is the first complete English translation of On the Purity of the Art of Logic, a handbook of logic written in Latin by English philosopher Walter Burley (c. 1275-1344/5). The work circulated in the Middle Ages in two versions, a shorter and a longer one, both translated here by Paul Vincent Spade. The translations arc based on the only complete edition of Burley's treatises, corrected by Spade on the basis of one of the surviving manuscripts. The book also includes an extensive introduction, explanatory notes, a table of corresponding passages between the two versions, a select annotated bibliography, and three indexes.

A contemporary of John Duns Scotus and William of Ockham, Burley was active at the universities of both Paris and Oxford. He became one of the most important figures in the transformation of medieval logic and semantics that took place in the early fourteenth century. Burley used new tools and techniques of logical and semantical analysis, yet in many cases he used them in defense of traditional views, such as a realist metaphysical theory of "universals". On the Purity of the Art of Logic shows both these sides of Burley -- the innovator and the conservative -- as well as some of the ways in which his views corresponded or clashed with those of William of Ockham.

The classical conception of reason (or logos) has been repeatedly attacked in the modern era. Its enemies range from Descartes, who complains that logos is not sufficiently useful or precise, to Derrida who hopes to liberate Western thought from its bondage to "logocentrism." At least since the time of Nietzsche, Plato has been damned as the chief architect of the classical conception of logos. He is accused of overvaluing reason and thereby devaluing the other, more human aspects of life. As it was originally formulated in Nietzsche's The Birth of Tragedy, Plato has been taken to be the arch-enemy of tragedy, which for Nietzsche was the most life-affirming of all the art forms of Greek culture. Originally published in 1990, The Tragedy of Reason defends Plato against his accusers. Employing a mode of exposition which exhibits Plato's position, Roochnik presents the Platonic conception of logos in confrontation with texts by Homer, Hesiod, Heraclitus, Aristotle, Descartes, Porty, and Derrida. In clear language, unencumbered by technical terminology, Roochnik shows that Platonic conception of logos is keenly aware of the strength of its opponents. The result is a presentation of Plato as a "tragic philosopher" whose conception of logos is characterized by an affirmation of its own limits as well as its goodness.
