In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

Wittgenstein's work remains, undeniably, now, that off one of those few philosophers who will be read by all future generations.

The paper is an exercise in descriptive ontology, with specific applications to problems in the geographical sphere. It presents a general typology of spatial boundaries, based in particular on an opposition between bona fide or physical boundaries on the one hand, and fiat or human-demarcation-induced boundaries on the other. Cross-cutting this opposition are further oppositions in the realm of boundaries, for example between: crisp and indeterminate, complete and incomplete, enduring and transient, symmetrical and asymmetrical. The resulting typology generates a corresponding (...) categorization of the different sorts of objects which (complete) boundaries determine or demarcate. The theory is applied first of all in the areas of geography and of administrative and property law. Indications are then given as to how the typology may be applied also in other fields where physical and fiat boundaries are at work, including the field of cognitive linguistics and the related field of the ontology of truth.

As a leading member of the Vienna Circle, Rudolph Carnap's aim was to bring about a "unified science" by applying a method of logical analysis to the empirical data of all the sciences. This work, first published in English in 1934, endeavors to work out a way in which the observation statements required for verification are not private to the observer. The work shows the strong influence of Wittgenstein, Russell, and Frege.

Ludwig Wittgenstein, who died in Cambridge in 1951, is one of the most powerful influences on contemporary philosophy, yet he shunned publicity and was essentially a private man. His friend Norman Malcolm (himself an eminent philosopher) wrote this remarkably vivid personal memoir ofWittgenstein, which was published in 1958 and was immediately recognized as a moving and truthful portrait of this gifted, difficult man.This edition includes also the complete text of the fifty-seven letters which Wittgenstein wrote to Malcolm over a period (...) of eleven years. Apart from the quotations in the Memoir these letters are previously unpublished. They reveal how much friendships mattered to Wittgenstein, and how concerned hewas for the health and well-being of his friends. His human qualities become evident; he advises, warns, jokes. and is grateful and affectionate.The volume also features a concise biographical sketch by another leading philosopher who was a friend of Wittgenstein, Georg Henrik von Wright.Much has been published about Wittgenstein since his death, but nothing brings us closer to the man himself than this modest classic of philosophical biography.

The influence of J. L. Austin on contemporary philosophy was substantial during his lifetime, and has grown greatly since his death, at the height of his powers, in 1960. Philosophical Papers, first published in 1961, was the first of three volumes of Austin's work to be edited by J. O. Urmson and G. J. Warnock. Together with Sense and Sensibilia and How to do things with Words, it has extended Austin's influence far beyond the circle who knew him or read (...) the handful of papers he published in journals.

Renowned moral philosopher Jonathan Glover confronts the brutal history of the twentieth century to unravel the mystery of why so many atrocities occurred. In a new preface, Glover brings the book through the post-September 11 era and into our own time—and asks whether humankind can "weaken the grip war has on us." _Praise for the first edition:_ “It is hard to imagine a more important book. Glover makes an overwhelming case for the need to understand our own inhumanity, and reduce (...) or eliminate the ways in which it can express itself—and he then begins the task himself. _Humanity _is_ _an extraordinary achievement.”—Peter Singer, Princeton University “This is an extraordinary book: brilliant, haunting and uniquely important. Almost 40 years ago a president read a best seller and avoided a holocaust. I like to think that some of the leaders and followers of tomorrow will read _Humanity._”_—_Steven Pinker, _New York Times Book Review_. (shrink)

Events in the history of thought have often moved as elements of drama—now tense, now tragic, now triumphant. And, it would appear, sometimes ludicrous. This latter is the thrust of a parody which Molière visited upon the savants of his day; he pictures a candidate for a medical degree being solemnly asked why opium puts people to sleep. Just as solemnly and sagaciously, the candidate replies..

This book investigates what it means, and whether it is coherent, to say that there is a God.

Richard Swinburne presents a substantially rewritten and updated edition of his most celebrated book. No other work has made a more powerful case for the probability of the existence of God. Swinburne gives a rigorous and penetrating analysis of the most important arguments for theism: the cosmological argument; arguments from the existence of laws of nature and the 'fine-tuning' of the universe; from the occurrence of consciousness and moral awareness; and from miracles and religious experience. He claims that while none (...) of these arguments are deductively valid, they do give inductive support to theism and that, even when the argument from evil is weighed against them, taken together they offer good grounds to support the probability that there is a God. The overall structure of the discussion and its conclusion have been retained for this new edition, but much has been changed in order to strengthen the argumentation and to take account of Swinburne's subsequent work on the nature of consciousness and the problem of evil, and of the latest philosophical and scientific writing, especially in respect of the laws of nature and the argument from fine-tuning. This is now the definitive version of a classic in the philosophy of religion. (shrink)

The authors demonstrate that unselfish behavior is in fact an important feature of both biological and human nature. Their book provides a panoramic view of altruism throughout the animal kingdom--from self-sacrificing parasites to the human capacity for selflessness--even as it explains the evolutionary sense of such behavior.

We take as our starting point a thesis to the effect that, at least for true judgments of many varieties, there are parts of reality which make such judgments are true. We argue that two distinct components are involved in this truthmaker relation. On the one hand is the relation of necessitation, which holds between an object x and a judgment p when the existence of x entails the truth of p. On the other hand is the dual notion of (...) projection, which holds between a judgment p and an object x when the truth of p entails the existence of x. A truthmaker for a judgment p is then a necessitator for p which satisfies the further constraint that it is part of p’s projection. We offer a formal theory of the truthmaker relation thus defined, exploiting ontological tools of basic mereology and the theory of dependence. We then apply the theory to a range of problems connected with generic expressions, ellipsis, vagueness, and indexical and perceptual judgments. (shrink)

Now, back to the picture. On the illusionist reading the spectators have become identical with Philip IV and Maria Ana. Given its position across the room and our position at the front of the scene, we would have to see ourselves in the mirror, but we only see the royal couple. Now what exactly is the painter on the left painting? Well it is obvious that he is painting us, that is, Philip IV and his wife. He looks straight at (...) us, scrutinizing our features, before applying the brush to the canvas. We have plainly caught him in the very act of painting us. But in what sort of picture is he painting us? The standard interpretation is that he is painting a full length portrait of what we see in the mirror. But there is an objection to that interpretation which seems to me fairly convincing. The canvas he is painting on is much too large for any such portrait. The canvas on which he is painting is indeed about as big as the one we are looking at, about 10 feet high and 8 feet wide . I think that the painter is painting the picture we are seeing; that is, he is painting Las Meninas by Velazquez. Although this interpretation seems to me defensible on internal grounds alone, there are certain bits of external evidence: as far as we know, the only portrait Velazquez ever painted of the royal couple is the one we are looking at, Las Meninas. Velazquez is plainly painting us, the royal couple, but there is no other picture in which he did that; and indeed he seldom used such large canvases for interiors. The Spinners is a large-scale interior but most of his big canvases are equestrian portraits of Spanish royalty. John R. Searle, professor of philosophy at the University of California at Berkeley, is the author of Speech Acts, The Campus War, and Expression and Meaning. (shrink)

You face two buttons. Pushing one will destroy Greensboro. Pushing the other will save it. There is no way for you to know which button saves and which destroys. What ought you to do? Answer: You ought to make the correct guess and push the button that saves Greensboro. Second question: Do you have an obligation to push the correct button?

The existing literature treats of several investigations with a certain bearing on the question which is roughly indicated by the title “Imperatives and Logic.” Some of those investigations, however, are entirely outside the scope of the present work.Mally sets himself the task of developing a “Logik des Willens” constituting a parallel to the usual logic, the “Logik des Denkens". In order to emphasize its independence, the author also calls this “Logik des Willens” “Deontik”, and he conceives it as being based (...) on the “Wesensgesetze” of will in the same way as the usual logic is conceived as being based on the “Wesensgesetze” of thought. The author develops a formalistic deductive system on the basis of 5 axioms of demands, including the axiom that there is at least one fact which is unconditionally demanded, and through a lengthy series of theorems he arrives at the sentence that what is unconditionally demanded is identical with what is actually the case: “was sein soll, ist Tatsache”. Similarly, the author develops a system of axioms for “right” volition, including the axiom that right volition is non-contradictory. (shrink)

Of the various accounts of negation that have been offered by logicians in the history of Western logic, that of negation as cancellation is a very distinctive one, quite different from the explosive accounts of modern "classical" and intuitionist logics, and from the accounts offered in standard relevant and paraconsistent logics. Despite its ancient origin, however, a precise understanding of the notion is still wanting. The first half of this paper offers one. Both conceptually and historically, the account of negation (...) as cancellation is intimately connected with connexivist principles such as ¬( ¬). Despite this, standard connexivist logics incorporate quite different accounts of negation. The second half of the paper shows how the cancellation account of negation of the first part gives rise to a semantics for a simple connexivist logic. (shrink)

In Contradiction advocates and defends the view that there are true contradictions, a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in 1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author’s reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the companion (...) volume, Doubt Truth to be a Liar, also published by Oxford University Press in 2006. (shrink)

We have seen that proofs of soundness of (Boolean) DS, EFQ and of ABS — and hence the legitimation of these inferences — can be achieved only be appealing to the very form of reasoning in question. But this by no means implies that we have to fall back on classical reasoning willy-nilly. Many logical theories can provide the relevant boot-strapping. Decision between them has, therefore, to be made on other grounds. The grounds include the many criteria familiar from the (...) philosophy of science: theoretical integrity (e.g., paucity of ad hoc hypotheses), adequacy to the data (explaining the data of inference —all inferences, not just those chosen from consistent domains!) and so on. This paper has not attempted to address these issues in general. All it demonstrates is that the charge that a dialetheist solution to the semantic paradoxes can be maintained only by making some intelligible notion ineffable cannot be made to stick. The dialetheist has a coherent position, endorsing the T-scheme, but rejecting DS, EFQ (even Boolean DS and EFQ) and ABS. And any argument to the effect that the relevant notions are both ineffable and intelligible begs the question. The case against consistent “solutions” to the semantic paradoxes therefore remains intact. (shrink)
