Book excerpt: Consequence is at the heart of logic; an account of consequence, of what follows from what, offers a vital tool in the evaluation of arguments. Since philosophy itself proceeds by way of argument and inference, a clear view of what logical consequence amounts to is of central importance to the whole discipline. In this book JC Beall and Greg Restall present and defend what thay call logical pluralism, arguing that the notion of logical consequence doesn't pin down one deductive consequence relation; it allows for many of them. In particular, they argue that broadly classical, intuitionistic, and relevant accounts of deductive logic are genuine logical consequence relations; we should not search for one true logic, since there are many. Their conclusions have profound implications for many linguists as well as for philosophers.

Book Synopsis Varieties of Logic by : Stewart Shapiro
Download or read book Varieties of Logic written by Stewart Shapiro and published by . This book was released on 2014 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Logical pluralism is the view that different logics are equally appropriate, or equally correct. Logical relativism is a pluralism according to which validity and logical consequence are relative to something. In Varieties of Logic, Stewart Shapiro develops several ways in which one can be a pluralist or relativist about logic. One of these is an extended argument that words and phrases like "valid" and "logical consequence" are polysemous or, perhaps better, are cluster concepts. The notions can be sharpened in various ways. This explains away the "debates" in the literature between inferentialists and advocates of a truth-conditional, model-theoretic approach, and between those who advocate higher-order logic and those who insist that logic is first-order. A significant kind of pluralism flows from an orientation toward mathematics that emerged toward the end of the nineteenth century, and continues to dominate the field today. The theme is that consistency is the only legitimate criterion for a theory. Logical pluralism arises when one considers a number of interesting and important mathematical theories that invoke a non-classical logic, and are rendered inconsistent, and trivial, if classical logic is imposed. So validity is relative to a theory or structure. The perspective raises a host of important questions about meaning. The most significant of these concern the semantic content of logical terminology, words like 'or', 'not', and 'for all', as they occur in rigorous mathematical deduction. Does the intuitionistic 'not', for example, have the same meaning as its classical counterpart? Shapiro examines the major arguments on the issue, on both sides, and finds them all wanting. He then articulates and defends a thesis that the question of meaning-shift is itself context-sensitive and, indeed, interest-relative. He relates the issue to some prominent considerations concerning open texture, vagueness, and verbal disputes. Logic is ubiquitous. Whenever there is deductive reasoning, there is logic. So there are questions about logical pluralism that are analogous to standard questions about global relativism. The most pressing of these concerns foundational studies, wherein one compares theories, sometimes with different logics, and where one figures out what follows from what in a given logic. Shapiro shows that the issues are not problematic, and that is usually easy to keep track of the logic being used and the one mentioned.
Book Synopsis Logical Pluralism and Logical Consequence by : Erik Stei
Download or read book Logical Pluralism and Logical Consequence written by Erik Stei and published by Cambridge University Press. This book was released on 2023-03-30 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Logical pluralism is the view that there is more than one correct logic. This is not necessarily a controversial claim but in its most exciting formulations, pluralism extends to logics that have typically been considered rival accounts of logical consequence – to logics, that is, which adopt seemingly contradictory views about basic logical laws or arguments. The logical pluralist challenges the philosophical orthodoxy that an argument is either deductively valid or invalid by claiming that there is more than one way for an argument to be valid. In this book, Erik Stei defends logical monism, provides a detailed analysis of different possible formulations of logical pluralism, and offers an original account of the plurality of correct logics that incorporates the benefits of both pluralist and monist approaches to logical consequence. His book will be valuable for a range of readers in the philosophy of logic.
Book Synopsis Pluralisms in Truth and Logic by : Jeremy Wyatt
Download or read book Pluralisms in Truth and Logic written by Jeremy Wyatt and published by Springer. This book was released on 2018-12-29 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume brings together 18 state-of-the art essays on pluralism about truth and logic. Parts I and II are dedicated to respectively truth pluralism and logical pluralism, and Part III to their interconnections. Some contributors challenge pluralism, arguing that the nature of truth or logic is uniform. The majority of contributors, however, defend pluralism, articulate novel versions of the view, or contribute to fundamental debates internal to the pluralist camp. The volume will be of interest to truth theorists and philosophers of logic, as well as philosophers interested in relativism, contextualism, metaphysics, philosophy of language, semantics, paradox, epistemology, or normativity.
Book Synopsis The Problem of Plurality of Logics by : Pavel Arazim
Download or read book The Problem of Plurality of Logics written by Pavel Arazim and published by Bloomsbury Publishing. This book was released on 2021-08-12 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the foundation of our rationality, logic has traditionally been considered fixed, stable and constant. This conception of the discipline has been challenged recently by the plurality of logics and in this book, Pavel Arazim extends the debate to offer a new view of logic as dynamic and without a definite, specific shape. The Problem of Plurality of Logics examines the origins of our standard view of logic alongside Kant's theories, the holistic view, the issue of logic's pragmatic significance and Robert Brandom's logical expressivism. Arazim then draws on proof-theoretical approaches to present a convincing argument for a dynamic version of logical inferentialism, which opens space for a new freedom to modify our own logic. He explores the scope, possibilities and limits of this freedom in order to highlight the future paths logic could take, as a motivation for further research. Marking a departure from logical monism and also from the recent doctrine of logical pluralism in its various forms, this book addresses current debates concerning the expressive role of logic and contributes to a lively area of discussion in analytic philosophy.
Book Synopsis Rationality and Logic by : Robert Hanna
Download or read book Rationality and Logic written by Robert Hanna and published by MIT Press. This book was released on 2009-01-23 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: An argument that logic is intrinsically psychological and human psychology is intrinsically logical, and that the connection between human rationality and logic is both constitutive and mutual. In Rationality and Logic, Robert Hanna argues that logic is intrinsically psychological and that human psychology is intrinsically logical. He claims that logic is cognitively constructed by rational animals (including humans) and that rational animals are essentially logical animals. In order to do so, he defends the broadly Kantian thesis that all (and only) rational animals possess an innate cognitive "logic faculty." Hanna's claims challenge the conventional philosophical wisdom that sees logic as a fully formal or "topic-neutral" science irreconcilably separate from the species- or individual-specific focus of empirical psychology.Logic and psychology went their separate ways after attacks by Frege and Husserl on logical psychologism—the explanatory reduction of logic to empirical psychology. Hanna argues, however, that—despite the fact that logical psychologism is false—there is an essential link between logic and psychology. Rational human animals constitute the basic class of cognizers or thinkers studied by cognitive psychology; given the connection between rationality and logic that Hanna claims, it follows that the nature of logic is significantly revealed to us by cognitive psychology. Hanna's proposed "logical cognitivism" has two important consequences: the recognition by logically oriented philosophers that psychologists are their colleagues in the metadiscipline of cognitive science; and radical changes in cognitive science itself. Cognitive science, Hanna argues, is not at bottom a natural science; it is both an objective or truth-oriented science and a normative human science, as is logic itself.

Book Synopsis Pragmatism, Pluralism, and the Nature of Philosophy by : Scott F. Aikin
Download or read book Pragmatism, Pluralism, and the Nature of Philosophy written by Scott F. Aikin and published by Routledge. This book was released on 2017-10-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past fifteen years, Aikin and Talisse have been working collaboratively on a new vision of American pragmatism, one which sees pragmatism as a living and developing philosophical idiom that originates in the work of the "classical" pragmatisms of Charles Peirce, William James, and John Dewey, uninterruptedly develops through the later 20th Century pragmatists (C. I. Lewis, Wilfrid Sellars, Nelson Goodman, W. V. O. Quine), and continues through the present day. According to Aikin and Talisse, pragmatism is fundamentally a metaphilosophical proposal – a methodological suggestion for carrying inquiry forward amidst ongoing deep disagreement over the aims, limitations, and possibilities of philosophy. This conception of pragmatism not only runs contrary to the dominant self-understanding among cotemporary philosophers who identify with the classical pragmatists, it also holds important implications for pragmatist philosophy. In particular, Aikin and Talisse show that their version of pragmatism involves distinctive claims about epistemic justification, moral disagreement, democratic citizenship, and the conduct of inquiry. The chapters combine detailed engagements with the history and development of pragmatism with original argumentation aimed at a philosophical audience beyond pragmatism.

Book Synopsis Explanatory Pluralism by : C. Mantzavinos
Download or read book Explanatory Pluralism written by C. Mantzavinos and published by Cambridge University Press. This book was released on 2016-05-26 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explaining phenomena is one of the main activities in which scientists engage. This book proposes a new philosophical theory of scientific explanation by developing and defending the position of explanatory pluralism with the help of the notion of 'explanatory games'. Mantzavinos provides a descriptive account of the explanatory activity of scientists in different domains and shows how they differ from commonsensical explanations offered in everyday life by ordinary people and also from explanations offered in religious contexts. He also shows how an evaluation and a critical appraisal of explanations put forward in different social arenas can take place on the basis of different values. Explanatory Pluralism provides solutions to all important descriptive and normative problems of the philosophical theory of explanation as illustrated in sophisticated case studies from economics and medicine, but also from mythology and religion.

Book Synopsis Evaluating Logical Pluralism by : David Pruitt
Download or read book Evaluating Logical Pluralism written by David Pruitt and published by . This book was released on 2009 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently some philosophers, in particular J.C. Beall and Greg Restall, have defended a view they refer to as 'logical pluralism'. This is the position that there are, in fact, several equally good but distinct logical systems according to which different arguments come out valid and invalid. No one system, they claim, is any more 'correct' than any other. I will have several criticisms of this view. I first argue that the phenomena of logical recapture causes problems for the pluralist. Somewhat roughly a logic is recaptured if, though all its argument forms were not valid in the full language, a restriction on the formulas of the language can render all those argument forms valid. I argue that once we recognize that this is possible the pluralist will require further argument if she is to contend that her account of the validity of the logic in question is superior to the logician who embraces recapture. My second criticism casts doubt on Beall and Restall's view that any time one specifies a set of truth conditions one has established a type of case in which claims may be true as well as a corresponding type of necessity. I will also make some methodological points about how to decide whether logical pluralism is true and which logic or logics are correct. And finally I will concede that a form of logical pluralism slightly different from the one endorsed by Beall and Restall may indeed be true. But ultimately I will have to leave the question of whether this alternative is indeed a legitimate form of logical pluralism to be settled on another occasion.

Book Synopsis An Introduction to the Philosophy of Logic by : Daniel Cohnitz
Download or read book An Introduction to the Philosophy of Logic written by Daniel Cohnitz and published by Cambridge University Press. This book was released on 2019-05-16 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Philosophy of logic is a fundamental part of philosophical study, and one which is increasingly recognized as being immensely important in relation to many issues in metaphysics, metametaphysics, epistemology, philosophy of mathematics, and philosophy of language. This textbook provides a comprehensive and accessible introduction to topics including the objectivity of logical inference rules and its relevance in discussions of epistemological relativism, the revived interest in logical pluralism, the question of logic's metaphysical neutrality, and the demarcation between logic and mathematics. Chapters in the book cover the state of the art in contemporary philosophy of logic, and allow students to understand the philosophical relevance of these debates without having to contend with complex technical arguments. This will be a major new resource for students working on logic, as well as for readers seeking a better understanding of philosophy of logic in its wider context.
Book Synopsis Unity and Plurality by : Massimiliano Carrara
Download or read book Unity and Plurality written by Massimiliano Carrara and published by Oxford University Press. This book was released on 2016 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unity and Plurality presents novel ways of thinking about plurality while casting new light on the interconnections among the logical, philosophical, and linguistic aspects of plurals. The volume brings together new work on the logic and ontology of plurality and on the semantics of plurals in natural language. Plural reference, the view that definite plurals such as 'the students' refer to several entities at once (the individual students), is an approach favoured by logicians and philosophers, who take sentences with plurals ('the students gathered') not to be committed to entities beyond individuals, entities such as classes, sums, or sets. By contrast, linguistic semantics has been dominated by a singularist approach to plurals, taking the semantic value of a definite plural such as 'the students' to be a mereological sum or set. Moreover, semantics has been dominated by a particular ontological view of plurality, that of extensional mereology. This volume aims to build a bridge between the two traditions and to show the fruitfulness of nonstandard mereological approaches. A team of leading experts investigates new perspectives that arise from plural logic and non-standard mereology and explore novel applications to natural language phenomena.
