Analytic philosophy is sometimes said to have particularly close connections to logic and to science, and no particularly interesting or close relation to its own history. It is argued here that although the connections to logic and science have been important in the development of analytic philosophy, these connections do not come close to characterizing the nature of analytic philosophy, either as a body of doctrines or as a philosophical method. We will do better to (...) understand analytic philosophy—and its relationship to continental philosophy—if we see it as a historically constructed collection of texts, which define its key problems and concerns. It is true, however, that analytic philosophy has paid little attention to the history of the subject. This is both its strength—since it allows for a distinctive kind of creativity—and its weakness—since ignoring history can encourage a philosophical variety of “normal science.”. (shrink)

Gyorgy Tamas works in the philosophy of logic, that difficult interdisciplin ary region wherein the notion of categories is both basic and subtle. To understand ways of thinking, to understand patterns of whatever is real, to recognize what is possible and to reject the nonsensical and the impossible is to comprehend the categories. This was a in thought and in fact, recurring motive of European thought from the earliest self-aware beginnings, and Tamas knows that history well, as his (...) critical respect demonstrates. Ancient, medieval, and modern thinkers appear in this book, set forth in their own words; and likewise we see that Tamas has built upon the historians and commentators, upon the pioneering historical investigation of the categories by Trendelenburg a century ago and by Bochenski in our days. Tamas has two principal goals here: to investigate the logic, which is to say the structure and the relations, of the philosophical categories; and to set forth the logic of thought which may then be based upon the critically established system of categories obtained by that investigation. Ancillary but of striking value is his style of historical relevance which enables the reader to engage in a discussion that is both analytically sharp and developmentally insightful. Furthermore, Tamas draws upon his contem porary colleagues with similar critical respect: Lukasiewicz, Quine, Patzig, Menne, Tavanets and others. (shrink)

First published in German in 1984 as volume 45 of Martin Heidegger’s collected works, this book is the first English translation of a lecture course he presented at the University of Freiburg in 1937–1938. Heidegger’s task here is to reassert the question of the essence of truth, not as a "problem" or as a matter of "logic," but precisely as a genuine philosophical question, in fact the one basic question of philosophy. Thus, this course is about the essence (...) of truth and the essence of philosophy. On both sides Heidegger draws extensively upon the ancient Greeks, on their understanding of truth as aletheia and their determination of the beginning of philosophy as the disposition of wonder. In addition, these lectures were presented at the time that Heidegger was composing his second magnum opus, Beiträge zur Philosophie, and provide the single best introduction to that complex and crucial text.

Key Terms in Logic offers the ideal introduction to this core area in the study of philosophy, providing detailed summaries of the important concepts in the study of logic and the application of logic to the rest of philosophy. A brief introduction provides context and background, while the following chapters offer detailed definitions of key terms and concepts, introductions to the work of key thinkers and lists of key texts. Designed specifically to meet the needs (...) of students and assuming no prior knowledge of the subject, this is the ideal reference tool for those coming to Logic for the first time. (shrink)

Is logic out of this world? This elusive question reveals a tension in our thinking about the basis of logic: both worldly and unworldly answers get something right and yet they conflict. My aim is to clarify the question and explore a conciliatory answer. I focus on a characterization of unworldliness in terms of ground. This allows for a distinction between proximal and distal unworldliness. That in turn reconfigures our approach to the question. It may now be taken (...) as asking for the proximal or the distal basis of logic. This helps alleviate the tension because the answer for the one needn’t conflict with a different answer for the other. I explore a case study culminating in an illustration of how a logical truth may indeed be proximally worldly but distally unworldly. I conclude by considering some potential extensions. (shrink)

Philosophers of logic are particularly interested in understanding the aims, epistemology, and methodology of logic. This raises the question of how the philosophy of logic should go about these enquires. According to the practice-based approach, the most reliable method we have to investigate the methodology and epistemology of a research field is by considering in detail the activities of its practitioners. This holds just as true for logic as it does for the recognised empirical and (...) abstract sciences. If we wish to systematically understand the aims and epistemology of logic, we are best placed achieving this by looking at what logicians do, rather than reflecting upon the nature of logic itself. In this entry, we outline the motivations for a practice-based approach towards the philosophy of logic and highlight its advantages over more “top-down” approaches, which attempt to infer conclusions about the nature of logic and its methodology on the basis of traditional assumptions about knowledge, metaphysics, or logic itself. We end by addressing several prominent concerns raised against the practice-based approach. (shrink)

Offering a collection of fifteen essays that deal with issues at the intersection of phenomenology, logic, and the philosophy of mathematics, this 2005 book is divided into three parts. Part I contains a general essay on Husserl's conception of science and logic, an essay of mathematics and transcendental phenomenology, and an essay on phenomenology and modern pure geometry. Part II is focused on Kurt Godel's interest in phenomenology. It explores Godel's ideas and also some work of Quine, (...) Penelope Maddy and Roger Penrose. Part III deals with elementary, constructive areas of mathematics. These are areas of mathematics that are closer to their origins in simple cognitive activities and in everyday experience. This part of the book contains essays on intuitionism, Hermann Weyl, the notion of constructive proof, Poincaré and Frege. (shrink)

There has been a long history of tension between feminists and feminist philosophy, on the one hand, and logic, on the other hand. This tension expresses itself in many ways, including claims that logic is a tool of the patriarchy, that logic/rationality/analytical tools in philosophy need to be rejected if women are to fully participate, that women = body and man = mind, that to do feminist philosophy one must do it as a situated, (...) embodied person, not as an impersonal, disembodied mind, that logic is “a masculine subject”. However the tension is expressed, it is women in logic and women logicians who are caught in between. The goal of my paper is to explore a conception of logic that not only is not inconsistent with being a feminist, but is actively welcoming of women as logicians. (shrink)

The beginnings of Indian Philosophy take us very far back to about the middle of the second millennium before christ.

This volume contains the proceedings of DEON2020/2021, the 15th International Conference on Deontic Logic and Normative Systems that was organized by the Munich Center for Mathematical Philosophy at LMU Munich (Germany) on 21st-24th July, 2021. The biennial DEON conferences are designed to promote interdisciplinary cooperation amongst scholars interested in linking the formal-logical study of normative concepts, normative language and normative systems with computer science, artificial intelligence, linguistics, philosophy, organization theory, and law.

"Philosophical logic" describes two distinct areas: the investigation of the fundamental concepts of logic, the formal investigation of alternatives and extensions to classical logic. The first is a philosophical discipline, concerned with notions like truth, propositions, necessity, logical consequence, vagueness, and reasoning. The second is a technical discipline, devoted to developing formal logical systems-modal logics, second-order logics, intuitionistic logics, relevance logics, logics of vagueness and conditionals-and proving things about them. Most texts in philosophical logic focus on (...) one of these areas, but in this book John MacFarlane treats them together in an integrated way, showing how philosophical considerations motivate the technical projects, and how the constraints revealed by the technical projects illuminate the philosophical issues. Topics covered include quantifiers, modal logic, indicative conditionals, model-theoretic and proof-theoretic characterizations of logical consequence, intuitionistic logic, fundamental logical disagreement, relevance logic, the relation of logic and reasoning, and vagueness. Each chapter is organized around suggested readings and includes exercises. Key Features: An integrated treatment of the technical and philosophical issues comprising philosophical logic Written by a leading authority on logicism and logical form and a successful expositor and teacher Designed to serve students taking only one course in logic beyond the introductory level Provides tools and concepts necessary to understand work in many areas of analytic philosophy Includes exercises, suggested readings, and suggestions for further exploration in each chapter.

Modal logic is one of the most widely applied logical formalisms. Systems of modal logic are being used in many disciplines, ranging from artificial intelligence, computer science, mathematics, formal grammar and semantics to philosophy. This volume presents substantial recent advances in the relational and the algorithmic treatment of modal logics. It contains papers from the fifth conference on "Advances in Modal logic," held in Manchester (UK) in September 2004. Written by leading experts in the field, the (...) present book is indispensable for any advanced student and researcher in pure and applied modal logic. (shrink)

The title of this volume -- Logic, God and Metaphysics -- is carefully chosen and, at the same time, descriptive of its main focus. In the twentieth century, the interests of most philosophers and theologians have fallen into only one of the three areas indicated -- logic, god or metaphysics. Since much of Anglo-American philosophy in this century has been analytic and antimetaphysical because of the influence of positivism, there have been few attempts at continuing metaphysical inquiry. (...) In the early part of the century, the logical atomists combined logic and metaphysics by arguing that the structure of reality is mirrored isomorphically in the structure of a formal, logically perfect, truth-functional language, but their effort was short-lived. Alfred North Whitehead and process philosophers have focused upon god and metaphysics but usually by adopting terminology and distinctions which are unique to certain systems -- making rigorous, logical analysis difficult or impossible. The papers included in this volume are illustrative of the application of careful, rigorous logical analysis to do critical philosophy of religion and what has been called constructive metaphysics.

Soft Logic is a fascinating study that links scientific and mathematical reasoning to literature and the arts. In this work, Joseph Grünfeld argues that justification by resemblance is more common in science than is generally recognized. That is, symbolic and metaphorical modes of thinking, which are largely analogical, often play a significant role in the interpretation of formal systems. Noting that twentieth century non-Aristotelian forms of reasoning have greatly expanded our understanding of what constitutes logic, Grünfeld explores a (...) wide range of relevant topics, including reasonableness, metaphor, deconstruction, postmodernism, aesthetics, art, and philosophy. In the process, he identifies the postmodernist implications of modern logic and develops how they may be applied to both science and art. Scholars of philosophy, aesthetics, and art will find this comprehensive and insightful work thought provoking. (shrink)

It is often said that ‘every logical truth is obvious’ (Quine 1970: 82), that the ‘axioms and rules of logic are true in an obvious way’ (Murawski 2014: 87), or that ‘logic is a theory of the obvious’ (Sher 1999: 207). In this chapter, I set out to test empirically how the idea that logic is obvious is reflected in the scholarly work of logicians and philosophers of logic. My approach is data-driven. That is to say, (...) I propose that systematically searching for patterns of usage in databases of scholarly works, such as JSTOR, can provide new insights into the ways in which the idea that logic is obvious is reflected in logical and philosophical practice, i.e., in the arguments that logicians and philosophers of logic actually make in their published work.

Does adherence to the principles of logic commit us to a particular way of viewing the world? Or are there ways of being – ways of behaving in the world, including ways of thinking, feeling, and speaking – that ground the normative constraints that logic imposes? Does the fact that assertions, the traditional elements of logic, are typically made about beings present a problem for metaphysical prospects of making assertions meaningfully about being? Does thinking about being accordingly (...) require revising or restricting logic's reach – and, if so, how is this possible? Or is there something precious about the very idea of thinking the limits of thinking? Contemporary scholars have become increasing sensitive to how Heidegger, much like Wittgenstein, instructively poses such questions. Heidegger on Logic is a collection of new essays by leading scholars who critically ponder the efficacy of his responses to them. (shrink)

After more than a decade teaching ancient Greek history and philosophy at University College, Oxford, British philosopher and political theorist Bernard Bosanquet resigned from his post to spend more time writing. He was particularly interested in contemporary social theory, and was involved with the Charity Organisation Society and the London Ethical Society. Much of his work focused on the place of logic in philosophy, especially its role in metaphysical thought - the area where he is considered to (...) have made his most important intellectual contributions. In 1888 he published this two-volume study of logic, addressing a variety of questions relating to logic, and drawing from the work of Hegel in his examination. In Volume 2, Bosanquet focuses on inference, arguing that it has a similar essence to judgment but is fundamentally different in that it is used to 'mediate' reality. (shrink)

Similar to learning the grammatical structures of a foreign language, one problem that students face in learning logic is that many of the operations and concepts they need to learn require more practice to fully master. To solve this problem, the author proposes the use of “repetitive exercises”, exercises that aim to develop a familiarity with a concept or operation through repeatedly focusing on that concept or operation. According to the author, the best method for implementing these exercises is (...) the use of on-line teaching environments, specifically WebCT, which allows instructors to develop exercises that they deem appropriate and allows for mechanical grading. Finally, the paper provides an overview of why WebCT is preferable to the use of Blackboard, and notes that the major drawback to the online solution is its poor support for the symbols used in propositional and predicate logic.

The early formal logicians (Frege, Russell, Peano et al.) were worried about differentiating logic from psychology. As a result, they interpreted logic in the most abstract way possible: as a theory about inference patterns whose terms lacked descriptive content. Such a theory was also acontextual. What they did not realize was that psychological concepts like expecting someone, doubting, pain etc. each had their own logic, a logic that had two features: it was contextually oriented and its (...) concepts had a restricted sensible application. This is still a recognizable sense of logic but broader in scope than the conceptions that Frege and Russell had in mind. (shrink)

One of Frege’s basic philosophical convictions has been that “a large part of the philosopher’s work consists—or at least should consist—in a fight against language.”. Besides, it is partly to his having yielded too easily to the deceptive suggestions of natural language that he himself attibuted, at the very end of his life, the failure of his attempt at defining numbers in logicist terms Nevertheless, he remained to the end convinced that the hopes raised by logic, one of whose (...) tasks is “to free us of the chains of language”, can only rest, in the last analysis, upon the possibility to trust the bulk of language and to make use of “such an imperfect instrument” to fight from the inside the uncertain fight that the philosopher must embark upon in order to free himself from its dominion and neutralize or eliminate its most damaging imperfections.

Philosophical action theory seems to be in pretty good shape. The same may not be true for the study of human action in economics. Famous is the rant that the study of human action in economics gives reason to tremble for the reputation of the subject. But how does this come about? Since economic action is about action, the broader study must surely have a strong impact on the more specific field. The paper sets out, from the ground up, how (...) an essential concept in economic theory–the concept of competition–can fundamentally benefit from insights derived exclusively from analytical action theory broadly conceived. In doing so, the paper delivers on an old Austrian promise: it is sometimes claimed that Austrian economists understand competition better than most economists. This may be a bold claim, since Austrian economists have neither traced the understanding of subjectivity to its very origin (the theory of intentionality), nor have they traced their sympathy for methodological individualism in relation to market processes to its very ground (the theory of (human) action). This paper aims to fill this gap. Moreover, by grounding an Austrian view of competition in analytic action theory, it succeeds in avoiding the serious problems of the dominant equilibrium approach. By explaining competition as rivalry, the paper draws on the philosophy and logic of human action to bring the (economic) agent back into play. In this way, a case is made for an integrated view of Austrian theory as an amalgam of Austrian economics and analytic action theory. (shrink)

Wolff's German Logic 1713 was a text book for Philosophy Students for many years.

This paper is an amended version of a talk Saul Kripke gave at the Eastern Division meeting of the APA in 1992 (an extended abstract was previously published as Kripke, 1992). It contains philosophical reflections and technical results concerning “Carnapian” quantified modal logic, that is, modal logic with quantification over individual concepts. The paper contains the fullest statement by the author available of (un)axiomatizability results he obtained in the 1970s. (The Editors.).

Johannes Steuchius was a prominent Swedish Lutheran theologian and academic, a descendant of celebrated Lutheran bishops and academics. Born in 1676 in Härnösand in northern Sweden, Steuchius moved with his family to Lund in 1694 when his father, Matthias Steuchius, the renowned academic and theologian, was appointed Bishop of Lund. After completing his studies in logic and metaphysics at Uppsala University, Steuchius was given the opportunity to attend some of Europe’s foremost Protestant academic institutions, a luxury afforded to few. (...) Steuchius’ disputatio uses Arabic logic to present an historical account of the development of philosophical thought in Arabia before and after the emergence of Islam. He first proposes that philosophy drew its origins from the East. His evidence for this claim is that many of the Greek philosophers, considered the forefathers of European philosophy, began cultivating their philosophical thinking as a result of exposure to ancient Eastern philosophy. After the introduction of Greek philosophy, it is agreed that dialectic was among the first of the arts the Arabs practiced. (shrink)

As a work of philosophically grounded literary criticism in the tradition of Stanley Cavell's ordinary language philosophy, Kenneth Dauber's The Logic of Sentiment: Stowe, Hawthorne, and Melville will be an altogether welcomed book among those for whom it is more instructive to think sentimentality alongside literary authors than to merely historicize—to "archeologize" or "genealogize"—it from an all-too-safe critical distance. Though primarily a book on sentiment, its theoretical through line is to think skepticism outside of the epistemological, to think (...) it in "nonepistemological terms". In line with what he elsewhere calls "ordinary language criticism," Dauber throughout the book follows the example of... (shrink)
