Problems of Rationality is the eagerly awaited fourth volume of Donald Davidson 's philosophical writings. From the 1960s until his death in August 2003 Davidson was perhaps the most influential figure in English-language philosophy, and his work has had a profound effect upon the discipline. His unified theory of the interpretation of thought, meaning, and action holds that rationality is a necessary condition for both mind and interpretation. Davidson here develops this theory to illuminate value judgements and how we understand (...) them; to investigate what the conditions are for attributing mental states to an object or creature; and to grapple with the problems presented by thoughts and actions which seem to be irrational. Anyone working on knowledge, mind, and language will find these essays essential reading. (shrink)

Dialetheism is the view that some contradictions are true. This is a view which runs against orthodoxy in logic and metaphysics since Aristotle, and has implications for many of the core notions of philosophy. Doubt Truth to Be a Liar explores these implications for truth, rationality, negation, and the nature of logic, and develops further the defense of dialetheism first mounted in Priest's In Contradiction, a second edition of which is also available.

In this investigation into Frege's philosophical views as a whole, the central focus is on his notion of sense, the conception that has proved most influential in the development of analytical philosophy, and around which the main problems of interpretation revolve.

One of the most important Anglo-American philosophers of our time here joins the current philosophical debate about the nature of truth. William P. Alston formulates and defends a realist conception of truth, which he calls alethic realism. This idea holds that the truth value of a statement depends on whether what the statement is about is as the statement says it is. Michael Dummett and Hilary Putnam are two of the prominent and widely influential contemporary philosophers whose anti-realist ideas Alston (...) attacks. (shrink)

Jennifer Fisher's ON THE PHILOSOPHY OF LOGIC explores questions about logic often overlooked by philosophers. Which of the many different logics available to us is right? How would we know? What makes a logic right in the first place? Is logic really a good guide to human reasoning? An ideal companion text for any course in symbolic logic, this lively and accessible book explains important logical concepts, introduces classical logic and its problems and alternatives, and reveals the rich and interesting (...) philosophical issues that arise in exploring the fundamentals of logic.

Philosophy of religion, in both its analytic and Continental streams, has been undergoing a renewal for some time now, and I seek to explore this transformation in the fortunes of the discipline by looking at how truth – and religious truth in particular – is conceptualised in both strands of philosophy. I begin with an overview of the way in which truth has been commonly understood across nearly all groups within the analytic tradition, and I will underscore the difficulties and (...) shortcomings of the analytic approach by comparing it with a Continental, and specifically Heideggerian, approach. I then proceed to a conception of truth that is even further removed from the analytic tradition, one that is prominent in the theology of Christianity and which identifies truth with Christ. The point of this detour through divergent understandings of truth is to show how philosophy of religion, whether analytic or Continental, remains entrenched in forms of thinking that will need to be overcome if it is to have a credible future.

Volume 1 examines the initial phase of the analytic tradition through the major contributions of three of its four founding giants—Gottlob Frege, Bertrand Russell, and G. E. Moore. Soames describes and analyzes their work in logic, the philosophy of mathematics, epistemology, metaphysics, ethics, and the philosophy of language. He explains how by about 1920 their efforts had made logic, language, and mathematics central to philosophy in an unprecedented way. But although logic, language, and mathematics were now seen as powerful tools (...) to attain traditional ends, they did not yet define philosophy. As volume 1 comes to a close, that was all about to change with the advent of the fourth founding giant, Ludwig Wittgenstein, and the 1922 English publication of his Tractatus, which ushered in a “linguistic turn” in philosophy that was to last for decades.

Substantivism is a general philosophical methodology advocating a substantive approach to philosophical theorizing. In this article, I present an overview of this methodology with a special emphasis on the field of truth. I begin with a framework for understanding what is at stake in the substantivist–deflationist debate and describe the substantivist critique of deflationism. I then proceed to discuss contemporary substantivism as a positive methodology, present examples of recent substantivist theories of truth, delineate several principles of philosophical substantivism, and connect (...) it to contemporary thought about the nature and methods of philosophy. Due to limitations of space, I am unable to discuss all the forms contemporary substantivism has taken. But I try to give a clear sense of the central principles, challenges, and promise of this methodology. (shrink)

Saying that x is ineffable seems to be paradoxical – either I cannot say anything about x, not even that it is ineffable – or I can say that it is ineffable, but then I can say something and it is not ineffable. In this article, I discuss Alston’s version of the paradox and a solution proposed by Hick which employs the concept of formal and substantial predicates. I reject Hick’s proposal and develop a different account based on some passages (...) from Pseudo-Dionysius’ Mystica Theologia. ‘God is ineffable’ is a metalinguistic statement concerning propositions about God: not all propositions about God are expressible in a human language.

Paradoxes are more than just intellectual puzzles - they raise substantive philosophical issues and offer the promise of increased philosophical knowledge. In this introduction to paradox and paradoxes, Doris Olin shows how seductive paradoxes can be, why they confuse and confound, and why they continue to fascinate. Olin examines the nature of paradox, outlining a rigorous definition and providing a clear and incisive statement of what does and does not count as a resolution of a paradox. The view that a (...) statement can be both true and false, that contradictions can be true, is seen to provide a challenge to the account of paradox resolution, and is explored. With this framework in place, the book then turns to an in-depth treatment of the Prediction Paradox, versions of the Preface/Fallibility Paradox, the Lottery Paradox, Newcomb's Problem, the Prisoner's Dilemma and the Sorites Paradox. Each of these paradoxes is shown to have considerable philosophical punch. Olin unpacks the central arguments in a clear and systematic fashion, offers original analyses and solutions, and exposes further unsettling implications for some of our most deep-seated principles and convictions.

What is truth? Michael Lynch defends a bold new answer to this question. Traditional theories of truth hold that truth has only a single uniform nature. All truths are true in the same way. More recent deflationary theories claim that truth has no nature at all; the concept of truth is of no real philosophical importance. In this concise and clearly written book, Lynch argues that we should reject both these extremes and hold that truth is a functional property. To (...) understand truth we must understand what it does, its function in our cognitive economy. Once we understand that, we'll see that this function can be performed in more than one way. And that in turn opens the door to an appealing pluralism: beliefs about the concrete physical world needn't be true in the same way as our thoughts about matters -- like morality -- where the human stain is deepest.

Within each of the major world religions a distinction is drawn between the ultimate ineffable Godhead or Absolute and the immediate object of worship or focus of religious meditation. I examine the notion of ineffability, or transcategoriality, in the influential Christian mystic Pseudo-Dionysius, who reconciles the divine ineffability with the authority of the Bible by holding that the biblical language is metaphorical, its function being to draw us towards the Godhead. If we extend this principle to other faiths we have (...) gone half way towards making the global history of religions intelligible. The other half consists in a recognition of the different human conceptualities and spiritual practices that give concrete form to the divine reality within religious experience. However, William Rowe, and Christopher Insole, have criticized this use of ineffability, and their arguments are responded to here. (shrink)

Human beings are both supremely rational and deeply superstitious, capable of believing just about anything and of questioning just about everything. Indeed, just as our reason demands that we know the truth, our skepticism leads to doubts we can ever really do so. In Walking the Tightrope of Reason, Robert J. Fogelin guides readers through a contradiction that lies at the very heart of philosophical inquiry. Fogelin argues that our rational faculties insist on a purely rational account of the universe, (...) yet at the same time, the inherent limitations of these faculties ensure that we will never fully satisfy that demand. As a result of being driven to this point of paradox, we either comfort ourselves with what Kant called "metaphysical illusions" or adopt a stance of radical skepticism. No middle ground seems possible and, as Fogelin shows, skepticism, even though a healthy dose of it is essential for living a rational life, "has an inherent tendency to become unlimited in its scope, with the result that the edifice of rationality is destroyed." In much Postmodernist thought, for example, skepticism takes the extreme form of absolute relativism, denying the basis for any value distinctions and treating all truth-claims as equally groundless. How reason avoids disgracing itself, walking a fine line between dogmatic belief and self-defeating doubt, is the question Fogelin seeks to answer. Reflecting upon the ancient Greek skeptics as well as such thinkers as Hume, Kant, Wittgenstein, Nietzsche, and Whitman, this book takes readers into--and through--some of philosophy's most troubling paradoxes.

Passages in Leibniz which have been understood to contain his statement of Leibniz law do not in fact contain any statement of that principle. Some of these passages contain a statement of the principle of the identity of indiscernibles, While others contain a statement of a principle about concept identity. The latter principle states that a concept, A, Is identical with a concept, B, If and only if a can be substituted for b in any proposition without change of truth (...) value. (shrink)

Engel argues that, although the minimalist conception of truth is basically right, it does not follow that truth can be eliminated from our philosophical thinking, as is claimed by some radical deflationists. In particular, he shows that some deflationist views have a definitively relativist and "postmodernist" ring and should be rejected. Even if a metaphysically substantive theory of truth has little chance to succeed, he argues, truth plays a central role as a norm or guiding value of our rational inquiries (...) and practices in the philosophy of knowledge and in ethics.

This is a concise, advanced introduction to current philosophical debates about truth. A blend of philosophical and technical material, the book is organized around, but not limited to, the tendency known as deflationism, according to which there is not much to say about the nature of truth. In clear language, Burgess and Burgess cover a wide range of issues, including the nature of truth, the status of truth-value gaps, the relationship between truth and meaning, relativism and pluralism about truth, and (...) semantic paradoxes from Alfred Tarski to Saul Kripke and beyond. Following a brief introduction that reviews the most influential traditional and contemporary theories of truth, short chapters cover Tarski, deflationism, indeterminacy, realism, antirealism, Kripke, and the possible insolubility of semantic paradoxes. The book provides a rich picture of contemporary philosophical theorizing about truth, one that will be essential reading for philosophy students as well as philosophers specializing in other areas.

Gila Sher approaches knowledge from the perspective of the basic human epistemic situation—the situation of limited yet resourceful beings, living in a complex world and aspiring to know it in its full complexity. What principles should guide them? Two fundamental principles of knowledge are epistemic friction and freedom. Knowledge must be substantially constrained by the world (friction), but without active participation of the knower in accessing the world (freedom) theoretical knowledge is impossible. This requires a grounding of all knowledge, empirical (...) and abstract, in both mind and world, but the fall of traditional foundationalism has led many to doubt the viability of this ‘classical’ project. Sher challenges this skepticism, charting a new foundational methodology, foundational holism, that differs from others in being holistic, world-oriented, and universal (i.e., applicable to all fields of knowledge). Using this methodology, Epistemic Friction develops an integrated theory of knowledge, truth, and logic. This includes (i) a dynamic model of knowledge, incorporating some of Quine’s revolutionary ideas while rejecting his narrow empiricism, (ii) a substantivist, non-traditional correspondence theory of truth, and (iii) an outline of a joint grounding of logic in mind and world. The model of knowledge subjects all disciplines to demanding norms of both veridicality and conceptualization. The correspondence theory is robust and universal yet not simplistic or naive, admitting diverse forms of correspondence. Logic’s grounding in the world brings it in line with other disciplines while preserving, and explaining, its strong formality, necessity, generality, and normativity. (shrink)

Presenting a fascinating analysis of the idea of what can't be said, this book ascertains whether the notion of there being a truth, or a state of affairs, or knowledge that can't be expressed linguistically is a coherent notion. The author distinguishes different senses in which it might be said that something can't be said. The first part looks at the question of whether ineffability is a coherent idea. Part two evaluates two families of arguments regarding whether ineffable states of (...) affairs actually exist: the argument from mysticism and the argument from epistemic boundedness. Part three looks more closely at the relation between mystic and non-mystic stances. In the fourth and final part the author distinguishes five qualitatively different types of ineffability. _Ineffability and Philosophy_ is a significant contribution to this area of research and will be essential reading for philosophers and those researching and studying the philosophy of language.

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 and that rational animals are essentially logical animals. In order to do so, he defends the broadly Kantian thesis that all 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. (shrink)

Ineffability—that which cannot be explained in words—lies at the heart of the Christian mystical tradition. It has also been part of every discussion of religious experience since the early twentieth century. Despite this centrality, ineffability is a concept that has largely been ignored by philosophers of religion. In this book, Bennett-Hunter builds on the recent work of David E. Cooper, who argues that the meaning of life can only be understood in terms of an ineffable source on which life depends, (...) and engages with the work of continental philosophers, such as Heidegger, Merleau-Ponty and Karl Jaspers. This is the first book to explore the concept of ineffability within contemporary philosophy of religion and provides a starting point for further scholarly debate. It will be of interest to scholars of philosophy of religion, theology, existentialism and phenomenology. -/- 'Bennett Hunter’s book is a timely contribution to the growing theological and philosophical literature on mystery and ineffability. Written in a lucid and elegant style, the book makes a convincing case for the ineffability of religious experience and explores its relationship to a sense that our lives are answerable to such experience.' — David E. Cooper. -/- 'Philosophers have long concentrated on linguistic forms in a way that has isolated language from the rest of life, and this isolation has increasingly obscured for them the vast range of things that cannot be spoken. Bennett-Hunter is not the first philosopher to try and map this distracted field, but he is remarkable in the width and sympathy of his approach to the highly various thinkers whom he invokes to illuminate it.' — Mary Midgley.

Can it be rational to be religious? Robert Audi gives a persuasive positive answer through an account of rationality and a rich, nuanced understanding of what religious commitment means. It is not just a matter of belief, but of emotions and attitudes such as faith and hope, of one's outlook on the world, and of commitment to live in certain ways.

Logic is essential to correct reasoning and also has important theoretical applications in philosophy, computer science, linguistics, and mathematics. This book provides an exceptionally clear introduction to classical logic, with a unique approach that emphasizes both the hows and whys of logic. Here Nicholas Smith thoroughly covers the formal tools and techniques of logic while also imparting a deeper understanding of their underlying rationales and broader philosophical significance. In addition, this is the only introduction to logic available today that presents (...) all the major forms of proof--trees, natural deduction in all its major variants, axiomatic proofs, and sequent calculus. The book also features numerous exercises, with solutions available on an accompanying website. -/- Logic is the ideal textbook for undergraduates and graduate students seeking a comprehensive and accessible introduction to the subject. -/- Provides an essential introduction to classical logic Emphasizes the how and why of logic Covers both formal and philosophical issues Presents all the major forms of proof--from trees to sequent calculus Features numerous exercises, with solutions available online The ideal textbook for undergraduates and graduate students .

There is a principle in things, about which we cannot be deceived, but must always, on the contrary, recognize the truth – viz. that the same thing cannot at one and the same time be and not be": with these words of the Metaphysics, Aristotle introduced the Law of Non-Contradiction, which was to become the most authoritative principle in the history of Western thought. However, things have recently changed, and nowadays various philosophers, called dialetheists, claim that this Law does not (...) hold unrestrictedly – that in peculiar circumstances the same thing may at the same time be and not be, and contradictions may obtain in the world. This book opens with an examination of the famous logical paradoxes that appear to speak on behalf of contradictions (e.g., the Liar paradox, the set-theoretic paradoxes such as Cantor’s and Russell’s), and of the reasons for the failure of the standard attempts to solve them. It provides, then, an introduction to paraconsistent logics – non-classical logics in which the admission of contradictions does not lead to logical chaos –, and their astonishing applications, going from inconsistent data base management to contradictory arithmetics capable of circumventing Gödel’s celebrated Incompleteness Theorem. The final part of the book discusses the philosophical motivations and difficulties of dialetheism, and shows how to extract from Aristotle’s ancient words a possible reply to the dialetheic challenge. How to Sell a Contradiction will appeal to anyone interested in non-classical logics, analytic metaphysics, and philosophy of mathematics, and especially to those who consider challenging our most entrenched beliefs the main duty of philosophical inquiry.

This book traces the linguistic turns in the history of modern philosophy and the development of the philosophy of language from Locke to Wittgenstein. It examines the contributions of canonical figures such as Leibniz, Mill, Frege, Russell, Wittgenstein, Austin, Quine, and Davidson, as well as those of Condillac, Humboldt, Chomsky, and Derrida. Michael Losonsky argues that the philosophy of language begins with Locke's Essay Concerning Human Understanding. He shows how the history of the philosophy of language in the modern period (...) is marked by a dichotomy between formal and pragmatic perspectives on language and that modern philosophy has not been able to integrate these two aspects of human language. Language as a human activity and language as a syntactic and semantic system remain distinct and competing focal points, although the interplay between these points of view has driven the development of the philosophy of language.

The object of attitudes valorized in the major religious traditions is typically regarded as maximally great. Conceptions of maximal greatness differ but theists believe that a maximally great reality must be a maximally great person or God. Theists largely agree that a maximally great person would be omnipresent, omnipotent, omniscient, and all good. They do not agree on a number of God's other attributes, however. We will illustrate this by examining the debate over God's impassibility in western theism and a (...) dispute over God's relation to the space time world in Indian theism. The entry concludes by examining some concepts of limited deities. (shrink)

The emergence of analytic philosophy has often been seen as inaugurating a linguistic turn in philosophy, a turn with profound anti-metaphysical implications. Metaphysics and epistemology, on this view, were replaced by logic and philosophy of language as forming the basis of philosophy. But if we look at the work of the four founders of analytic philosophy, Frege, Russell, Moore and Wittgenstein, we find metaphysical conceptions at the heart of their endeavours. Frege, for example, regarded numbers and the truth-values as logical (...) objects, and the ontological distinction between concept and object was fundamental to his philosophy. Both Russell and Moore in their early work developed a realist view of propositions, and even when Russell abandoned the metaphysics of propositions in his later work, this was simply replaced by a metaphysics of facts. Wittgenstein, too, in the Tractatus, articulated a raft of theses that seem paradigmatically metaphysical, though their precise status has been controversial. In this paper I outline some of the key metaphysical conceptions of Frege, Russell, Moore and the early Wittgenstein, and explore the connections with their logical views, taking as my main example the problem of relational propositions. I end by addressing the question of the status of the metaphysical statements that Frege and Wittgenstein, in particular, found themselves making. (shrink)
