Book Description
Saving Truth from Paradox is an ambitious investigation into paradoxes of truth and related issues, with occasional forays into notions such as vagueness, the nature of validity, and the Gödel incompleteness theorems. Hartry Field presents a new approach to the paradoxes and provides a systematic and detailed account of the main competing approaches. Part One examines Tarski's, Kripke’s, and Lukasiewicz’s theories of truth, and discusses validity and soundness, and vagueness. Part Two considers a wide range of attempts to resolve the paradoxes within classical logic. In Part Three Field turns to non-classical theories of truth that that restrict excluded middle. He shows that there are theories of this sort in which the conditionals obey many of the classical laws, and that all the semantic paradoxes (not just the simplest ones) can be handled consistently with the naive theory of truth. In Part Four, these theories are extended to the property-theoretic paradoxes and to various other paradoxes, and some issues about the understanding of the notion of validity are addressed. Extended paradoxes, involving the notion of determinate truth, are treated very thoroughly, and a number of different arguments that the theories lead to "revenge problems" are addressed. Finally, Part Five deals with dialetheic approaches to the paradoxes: approaches which, instead of restricting excluded middle, accept certain contradictions but alter classical logic so as to keep them confined to a relatively remote part of the language. Advocates of dialetheic theories have argued them to be better than theories that restrict excluded middle, for instance over issues related to the incompleteness theorems and in avoiding revenge problems. Field argues that dialetheists’ claims on behalf of their theories are quite unfounded, and indeed that on some of these issues all current versions of dialetheism do substantially worse than the best theories that restrict excluded middle.

Book Description
Christians trying to model their lives after Jesus may find that He gets buried under lists, rules, and formulas. Now bestselling author Randy Alcorn offers a simple two-point checklist for Christlikeness based on John 1:14. The test consists of balancing grace and truth, equally and unapologetically. Grace without truth deceives people, and ceases to be grace. Truth without grace crushes people, and ceases to be truth. Alcorn shows the reader how to show the world Jesus -- offering grace instead of the world's apathy and tolerance, offering truth instead of the world's relativism and deception. Grace or Truth…or Both? Truth without grace breeds self-righteousness and crushing legalism. Grace without truth breeds deception and moral compromise. Is it possible to embrace both in balance? Jesus did. Randy Alcorn offers a simple yet profound two-point checklist of Christlikeness. “In the end,” says Alcorn, “we don’t need grace or truth. We need grace and truth. And for people to see Jesus in us, they must see both.”

Book Description
In Truth Without Paradox, David Johnson purports to solve several of the traditional problems of metaphysics, pertaining to truth, logic, similitude, morality, and God. In the first chapter, he argues (in three independent ways) against the general acceptability of the schema 'if p then it is true that p', claiming thereby to resolve the paradoxes of the liar and of the sorites. In the second chapter, he clarifies what was (and what was not) settled by Quine about "truth by convention." In the third chapter, he attempts to shed light on the obscure notion of "sameness," or "uniformity," especially in its application to inductive extrapolation and to the grue paradox. In the fourth chapter, he purports to solve the "Is/Ought" problem of moral philosophy. The fifth and final chapter, which will be of interest to philosophers of religion, contains what the author calls an historical proof of the existence of God, based on (among other things) a resolution of the lottery paradox.

Book Description
The Liar paradox raises foundational questions about logic, language, and truth (and semantic notions in general). A simple Liar sentence like 'This sentence is false' appears to be both true and false if it is either true or false. For if the sentence is true, then what it says is the case; but what it says is that it is false, hence it must be false. On the other hand, if the statement is false, then it is true, since it says (only) that it is false. How, then, should we classify Liar sentences? Are they true or false? A natural suggestion would be that Liars are neither true nor false; that is, they fall into a category beyond truth and falsity. This solution might resolve the initial problem, but it beckons the Liar's revenge. A sentence that says of itself only that it is false or beyond truth and falsity will, in effect, bring back the initial problem. The Liar's revenge is a witness to the hydra-like nature of Liars: in dealing with one Liar you often bring about another. JC Beall presents fourteen new essays and an extensive introduction, which examine the nature of the Liar paradox and its resistance to any attempt to solve it. Written by some of the world's leading experts in the field, the papers in this volume will be an important resource for those working in truth studies, philosophical logic, and philosophy of language, as well as those with an interest in formal semantics and metaphysics.

Book Description
In this rigorous investigation into the logic of truth Anil Gupta and Nuel Belnap explain how the concept of truth works in both ordinary and pathological contexts. The latter include, for instance, contexts that generate Liar Paradox. Their central claim is that truth is a circular concept. In support of this claim they provide a widely applicable theory (the "revision theory") of circular concepts. Under the revision theory, when truth is seen as circular both its ordinary features and its pathological features fall into a simple understandable pattern. The Revision Theory of Truth is unique in placing truth in the context of a general theory of definitions. This theory makes sense of arbitrary systems of mutually interdependent concepts, of which circular concepts, such as truth, are but a special case.

Book Description
The question of truth has never been more urgent than today, when the distortion of facts and the imposition of pseudo-realities in the service of the powerful have become the order of the day. In The Paradox of Being Poul Andersen addresses the concept of truth in Chinese Daoist philosophy and ritual. His approach is unapologetically universalist, and the book may be read as a call for a new way of studying Chinese culture, one that does not shy away from approaching “the other” in terms of an engagement with “our own” philosophical heritage. The basic Chinese word for truth is zhen, which means both true and real, and it bypasses the separation of the two ideas insisted on in much of the Western philosophical tradition. Through wide-ranging research into Daoist ritual, both in history and as it survives in the present day, Andersen shows that the concept of true reality that informs this tradition posits being as a paradox anchored in the inexistent Way (Dao). The preferred way of life suggested by this insight consists in seeking to be an exception to ordinary norms and rules of behavior which nonetheless engages what is common to us all.

Book Description
The problem of truth and the liar paradox is one of the most extensive problems of philosophy. The liar paradox can be avoided by assuming a so-called theory of partial truth instead of a classical theory of truth. Theories of partial truth, however, cannot solve the so-called strengthened liar paradox, which is the problem that many semantic statements about the so-called strengthened liar cannot be true in a theory of partial truth. If such semantic statements were true in the theory, another paradox would emerge. To proponents of contextual accounts, which assume that the concept of truth is context-dependent, the strengthened liar paradox is the core of the liar problem. This book provides an overview of current contextual approaches to the strengthened liar paradox. For this purpose, the author investigates formal theories of truth that result from formal reconstructions of such contextual approaches.

Book Description
Truth is one of the oldest and most central topics in philosophy. Formal theories explore the connections between truth and logic, and they address truth-theoretic paradoxes such as the Liar. Three leading philosopher-logicians now present a concise overview of the main issues and ideas in formal theories of truth. Beall, Glanzberg, and Ripley explain key logical techniques on which such formal theories rely, providing the formal and logical background needed to develop formal theories of truth. They examine the most important truth-theoretic paradoxes, including the Liar paradoxes. They explore approaches that keep principles of truth simple while relying on nonclassical logic; approaches that preserve classical logic but do so by complicating the principles of truth; and approaches based on substructural logics that change the shape of the target consequence relation itself. Finally, inconsistency and revision theories are reviewed, and contrasted with the approaches previously discussed. For any reader who has a basic grounding in logic, this book offers an ideal guide to formal theories of truth.
