We already have a distinction between the intension and extension of terms. This is not simply the distinction that is operative in philosophy of mind, body, and action. There, the concern is with things, and with a physicalistic or a mentalistic account of them. The physicalist says he supports an ‘extensional’ analysis of things, the mentalist an ‘intensional’. So, the physicalist says that, in the end, only ‘the extensional language of physical science’ will do in ontology. But, associating this physical-mental (...) dichotomy with the intension-extension distinction as applied to terms is misleading. The ontological issue is obscured by the association. An ontologist wants, like Spinoza or Berkeley, to know whetherthingsare extended or not, and in what respects. This question makes central the concept of space, or more generally of ‘field’, ‘domain’. Unfortunately, the same word ‘extension’ is used also for the spread or location of athingin space. To dissociate the extension of a term, a logical notion, from the ontological notion of the spatial status of a thing, I introduce the new word ‘extention’. This coinage correlates, not with the ‘intension’ of terms—the logical correlate of ‘extension’—but with ‘intention’, a word that fortunately already has common currency, and reeks with connotations that have logical ties with ‘consciousness’. So, from here on, we have two dichotomies: intension-extension applying to terms, and intention-extention applying to things. Since terms are things, both sorts of considerations are relevant to them, the logical one and the ontological. Only the latter applies to, say, stones or persons, since these are not linguistic terms. (shrink)

Kripke's own view of the 'inner life' as comprised of '"qualia"' that have no 'natural "external" manifestation' leads him into misinterpreting wittgenstein's denials on this count. so kripke gives wittgenstein's account a paradoxical and sceptical cast which misrepresents it, making it look as if it called for a sceptical solution and a 'warranted assertibility' theory of truth. but wittgenstein was making sport of the 'inner-outer' (subjective-objective) distinction with the rapier of his suggestion that psychological talk is not regulated by the (...) logic of object-designation-and-property talk. a conventional reading can mistake this as a "simple" denial of logic wholesale that jettisons rules, meanings, and their ilk.

This book presents the thesis that appearances should not be viewed simply as functions of a prevailing conceptual system. In addition to making a valuable contribution to the study of the mind/body problem, distinguished between first and second-order extensions, the book provides an excellent evaluation of the philosophy of physicalism and develops an exceptionally sound theory of personhood.

The human body is ?transmogrified? (caricatured) under physicalistic descriptions of it. These imply that it is a contingent fact that rational beings such as human persons have the sort of bodies they do have. (Or, that, say, baboons are not rational creatures.) The human body is ?transfigured? under a description that makes it necessary to the performance of rational functions, including speaking a language. Any view of the matter that excludes this notion, either by reduction to the physicalist treatment or (...) simple denial, is inadequate. (shrink)

By their nature, the most vexing social problems reflect collisions between social and economic interests of parties with highly divergent views and perspectives on the cause and character of what is at issue and the consequences that flow from it. Conflicts around biotechnology applications are good examples of these problems. When considering the potential consequences of proposed biotechnology applications, an enormous range of perspectives arise reflecting the breadth of different and often competing interests with a stake in life's future.This essay (...) starts from an assumption that the traditional tool of cost‐benefit analysis is not adequate for adjudicating competing claims around the introduction of new biotechnology applications. It tends to require implicit simplifying assumptions that reduce or mask true underlying levels of complexity and uncertainty, and the results it produces deliver a definitive and singular answer, as opposed to a multiplicity of outcomes. In this essay, I describe some of the key elements of formal scenario planning to show how CBA could be redeployed as a supporting tool within the broader decision support methodology of formal scenario planning.

Now, if you were asked, "Did you see what is in the picture?" and answered "No," your companion might reasonably say that you did not see the picture after all. This he could say on the strength of the other part of the concept of a picture. To see a picture in this sense is at least to see what it pictures, and this is what is "in" it. Your dog never sees the picture, in this sense. As for you, (...) you normally see, or look for, what is "in" the picture, tending to overlook the picture in the first sense; such that, having noticed what appears in the picture, you would have to go back for another look at it to answer questions about how high above the floor it was hung, what sort of frame it had, how the paint was put on the canvas, etc. (shrink)

Lord Acton, in his letter to the contributors to the Cambridge Modern History, wrote: “By Universal History, I understand that which is distinct from the combined histories of all countries … and is not a burden on the memory but an illumination of the soul.” If we replace “history” by the more general term “knowledge,” we get the statement of an ideal cherished by the great men of every age—those lonely pioneers to whom book-learning is an intellectual gloom more treacherous (...) than the natural gloom of night, since it fools men into thinking that it is a light by which men can see. The pioneers in thought, or indeed in any field, have made a secret treaty with nature. They smile with her at the robed and tassled scholar who, “Bewundrung von Kindern und Affen,” can “lecture plausibly about anything and get himself admired by the less learned.” Those pioneers, those men who—as someone has said—have thought according to no one and have made the human race think according to them, see by an intuitive insight, an illumination of the soul. Einstein, in his prologue to Planck's book Where is Science Going?, writes: “There is only the way of intuition. … The state of mind which furnishes the driving power here resembles that of the devotee or the lover. The long-sustained effort is not inspired by any set plan or purpose. It arises from a hunger of the soul.” We have not quoted a poet, but the greatest of mathematical physicists. (shrink)

Attention has been drawn, particularly since Kant, to propositions which can not have negative instances. They used to be called a priori, axioms, first principles. Today, they are usually called postulates—C. I. Lewis uses both the old and new terminology—because there is a growing recognition of the fact that at least some of them are not “necessary” in the traditional sense. Kant placed a limitation on the apriorism of the continental rationalists. Current epistemologists and logicians have outstripped Kant in the (...) direction signalled by him. Both he and they, however, concur in the opinion that apriori propositions are subject to negation of a sort. The Kantian dinge-an-sich, though they can not contradict these propositions by being negative instances of them, do nevertheless stand to them in the relation of insubordination, thereby exerting on them a “negative action” of a sort. And, according to current views, there are instances which, though they fall outside the range of significance of a proposition or system and hence can not contradict it, do nevertheless tend to bring about a revision of it by a negative action of some sort. The purpose of this brief essay is to coin a convenient name for such instances and to describe certain properties of their peculiar negative action. (shrink)

Picture-theories of visual perception usually maintain that, when something is simply seen, then the seer “has” a picture of the thing, the thing is the primary cause of the picture, the thing in itself is not the primary object of sight, and it is the picture itself that is the primary object of visual awareness.I shall argue in this essay that there are not only proper, but required, senses in which the first three of these propositions are true, but that (...) the fourth is always false or that one never simply sees the picture. Rather, what is thus seen is always in the picture, never the picture itself. The grounds on which I make this complex point will also undo the time-lag argument, at least in the standard interpretation of it associated with the false fourth proposition above. (shrink)

F. H. Bradley’s early essay “My Station and Its Duties” might as well have been entitled “The Philosopher’s Station and Its Duties.” The philosopher takes a god’s-eye view of man as finally realizing himself only in the philosophical consciousness of the Whole. Thus it is the philosopher’s duty to remind man qua man of this Whole as the ultimate determinant of all Duty. But, said Bradley, some-where between this ultimate on the one hand and the very local thing called the (...) family on the other is a man’s profession. This too is an ethereal or spiritual ‘organism’ within the all-inclusive one, with internal requirements of its own more special sort. I focus on this partial thing, attributing more autonomy to it than Bradley’s totalitarian view would tolerate. And the profession I select for anxious consideration is the teacher’s. It is the teacher’s station and its duties that are here my ultimate concern. What these duties have become is a serious matter, owing especially to recent techno-logical developments and what this is doing to people and to the things they live with, in our time. But the panacea I am going to recommend in this connection is rather the opposite of the one suggested by the numerous thinkers who are worried about this. (shrink)

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on twentieth-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A.C. Grayling makes Wittgenstein's thought accessible to the general reader by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

Philosopher Roger Scruton offers a wide-ranging perspective on philosophy, from logic to aesthetics, written in a lively and engaging way that is sure to stimulate debate. Rather than producing a survey of an academic discipline, Scruton reclaims philosophy for worldly concerns.

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof? -/- The answer is an emphatic yes, as I explain in this article. I argue that non-deductive justification is in fact pervasive in mathematics, and that it (...) is in good epistemic standing. (shrink)

Bertrand Russell (1872-1970) is one of the most famous and important philosophers of the twentieth century. In this account of his life and work A.C. Grayling introduces both his technical contributions to logic and philosophy, and his wide-ranging views on education, politics, war, andsexual morality. Russell is credited with being one of the prime movers of Analytic Philosophy, and with having played a part in the revolution in social attitudes witnessed throughout the twentieth-century world. This introduction gives a clear survey (...) of Russell's achievements across their wholerange. (shrink)

The 1981 Dahlem conference was a catalyst for contemporary evolutionary developmental biology (Evo-devo). This introductory chapter rehearses some of the details of the history surrounding the original conference and its associated edited volume, explicates the philosophical problem of conceptual change that provided the rationale for a workshop devoted to evaluating the epistemic revisions and transformations that occurred in the interim, explores conceptual change with respect to the concept of evolutionary novelty, and highlights some of the themes and patterns in the (...) different contributions to the present volume, Conceptual Change in Biology: Scientific and Philosophical Perspectives on Evolution and Development.

'The unconsidered life is not worth living' - Socrates. Thinking about life, what it means and what it holds in store does not have to be a despondent experience, but rather can be enlightening and uplifting. A life truly worth living is one that is informed and considered so a degree of philosophical insight into the inevitabilities of the human condition is inherently important and such an approach will help us to deal with real personal dilemmas. This book is an (...) accessible, lively and thought-provoking series of linked commentaries, based on A. C. Grayling's 'The Last Word' column in the Guardian. Its aim is not to persuade readers to accept one particular philosophical point of view or theory, but to help us consider the wonderful range of insights which can be drawn from an immeasurably rich history of philosophical thought. Concepts covered include courage, love, betrayal, ambition, cruelty, wisdom, passion, beauty and death. This will be a wonderfully stimulating read and act as an invaluable guide as to what is truly important in living life, whether facing success, failure, justice, wrong, love, loss or any of the other profound experience life throws out.

In this benchmark five-volume study, originally published between 1922 and 1955, Surendranath Dasgupta examines the principal schools of thought that define Indian philosophy. A unifying force greater than art, literature, religion, or science, Professor Dasgupta describes philosophy as the most important achievement of Indian thought, arguing that an understanding of its history is necessary to appreciate the significance and potentialities of India's complex culture. Volume I offers an examination of the Vedas and the Brahmanas, the earlier Upanisads, and the six (...) systems of Indian philosophy. (shrink)

"A distinctive voice somewhere between Mark Twain and Michel Montaigne" is how Psychology Today described A.C. Grayling. In Life, Sex, and Ideas: The Good Life Without God, readers have the pleasure of hearing this distinctive voice address some of the most serious topics in philosophy--and in our daily lives--including reflections on guns, anger, conflict, war; monsters, madness, decay; liberty, justice, utopia; suicide, loss, and remembrance. A civilized society, says Grayling, is one which never ceases having a discussion with itself about (...) what human life should best be. In this book, Grayling adds to this discussion a series of short informal essays about ethics, ideas, and culture. A recurring theme is religion, of which he writes "there is no greater social evil." He argues, for instance, that liberal education is better than religion for inculcating moral values. "Education in literature, history, and appreciation of the arts," he says, "opens the possibility for us to live more reflectively and knowledgeably, especially about the nature and variety of human experience. That in turn increases our capacity for understanding others better, so that we can treat them with respect and sympathy, however different their outlook on life." Thought provoking rather than definitive, these essays don't tell readers what to think, but only note what has been thought about how it is best to live. A person who does not think about life, the author reminds us, is like a stranger mapless in a foreign land. These brief and suggestive essays offer us the outlines of a map, with avenues of thought that are a pleasure to wander down. (shrink)
