We examine the notion of conditionals and the role of conditionals in inductive logics and arguments. We identify three mistakes commonly made in the study of, or motivation for, non-classical logics. A nonmonotonic consequence relation based on evidential probability is formulated. With respect to this acceptance relation some rules of inference of System P are unsound, and we propose refinements that hold in our framework.

Henry Kyburg’s lottery paradox (1961, p. 197) arises from considering a fair 1000 ticket lottery that has exactly one winning ticket. If this much is known about the execution of the lottery it is therefore rational to accept that one ticket will win. Suppose that an event is very likely if the probability of its occurring is greater than 0.99. On these grounds it is presumed rational to accept the proposition that ticket 1 of the lottery will not win. Since (...) the lottery is fair, it is rational to accept that ticket 2 won’t win either—indeed, it is rational to accept for any individual ticket i of the lottery that ticket i will not win. However, accepting that ticket 1 won’t win, accepting that ticket 2 won’t win, . . . , and accepting that ticket 1000 won’t win entails that it is rational to accept that no ticket will win, which entails that it is rational to accept the contradictory proposition that one ticket wins and no ticket wins.

I adopt a cladistic view of species, and explore the possibility that there exists an equally valuable cladistic view of organismic traits. This suggestion seems to run counter to the stress on functional views of biological traits in recent work in philosophy and psychology. I show how the tension between these two views can be defused with a multilevel view of biological explanation. Despite the attractions of this compromise, I conclude that we must reject it, and adopt an essentially cladistic (...) conception of biological traits. (shrink)

The widely cited Nuffield Council on Bioethics ‘Intervention Ladder’ structurally embodies the assumption that personal autonomy is maximized by non-intervention. Consequently, the Intervention Ladder encourages an extreme ‘negative liberty’ view of autonomy. Yet there are several alternative accounts of autonomy that are both arguably superior as accounts of autonomy and better suited to the issues facing public health ethics. We propose to replace the one-sided ladder, which has any intervention coming at a cost to autonomy, with a two-sided ‘Balanced Intervention (...) Ladder,’ where intervention can either enhance or diminish autonomy. We show that not only the alternative, richer accounts of autonomy but even Mill’s classic version of negative liberty puts some interventions on the positive side of the ladder. (shrink)

We examined the hypothesis that a tendency to experience the world in terms of a sense of ‘special’ connection is responsible for the self-transcendent value dimension identified by multi-dimensional scaling and constitutes a common factor for different religious and non-religious interpretations of spirituality. Eight different groups were studied including: six different types of faith leaders in India and the UK, people who self-rated as spiritual but not religious, and those self-rating as neither spiritual nor religious. They completed a questionnaire that (...) assessed the strength of their spirituality irrespective of type and the experience of special connection to the following categories: people, nature, places and the universe, with and without using the term spiritual. For all eight samples the different types of connection were highly inter-correlated, and self-perceived spirituality correlated with the sum of connection items irrespective of whether items included the term spiritual or not. Variation between groups in the size of the latter correlation was consistent with different interpretations of spirituality in those groups. Although the meaning of spirituality is socially constructed, variability within faith leader groups suggests that its interpretation is also affected by personality. (shrink)

Philosophers have had an interest in language from the earliest times but the twentieth century, with its so-called 'linguistic turn' in philosophy, has seen a huge expansion of work focused specifically on language and its foundations. No branch of philosophy has been unaffected by this shift of emphasis. It is timely at the end of the century to review and assess the vast range of issues that have been developed and debated in this central area. The distinguished international contributors present (...) a clear, accessible guide to the fundamental questions raised by the philosophers about language. Contributions include Graeme Forbes on necessity, Susan Haack on deviant logics, Paul Horwich on truth, Charles Travis on Wittgenstein, L.J. Cohen on linguistic philosophy, Ruth Kempson on semantics and syntax and Christopher Hookway on ontology, to name but a few. A wide range of topics are covered from the metaphysics and ontology of language, language and mind, truth and meaning, to theories or reference, speech act theory, philosophy of logic and formal semantics. There are also articles on key figures from the twentieth century and earlier. Based on the foundation provided by the award-winning Encyclopedia of Language and Linguistics this single volume provides a collection of articles that will be an invaluable reference tool for all those interested in the area of philosophy of language, and also to those in cognitive science and psychology. All the articles have been thoroughly revised and updated. This volume gives a unique survey of topics that are at the very core of contemporary philosophy. (shrink)

This series provides individual textbooks on early Greek poetry, on Greek drama, on philosophy, history and oratory, and on the literature of the Hellenistic period and of the Empire. A chapter on books and readers in the Greek world concludes Part 4. Each part has its own appendix of authors and works, a list of works cited, and an index.

The period from the eighth to the fifth centuries B.C. was one of extraordinary creativity in the Greek-speaking world. Poetry was a public and popular medium, and its production was closely related to developments in contemporary society. At the time when the city states were acquiring their distinctive institutions epic found the greatest of all its exponents in Homer, and lyric poetry for both solo and choral performance became a genre which attracted poets of the first rank, writers of the (...) quality of Sappho, Alcaeus and Pindar, whose influence on later literature was to be profound. This volume covers the epic tradition, the didactic poems of Hesiod and his imitators, and the wide-ranging work of the iambic, elegiac and lyric poets of what is loosely called the archaic age. The contributors make use of recent papyrus finds to fill out the picture of a cosmopolitan and highly sophisticated literary culture which had not yet found its intellectual centre in Athens.

This volume ranges in time over a very long period and covers the Greeks' most original contributions to intellectual history. It begins and ends with philosophy, but it also includes major sections on historiography and oratory. Although each of these areas had functions which in the modern world would not be considered 'Literary', the ancients made a less sharp distinction between intellectual and artistic production, and the authors included in this volume are some of Europe's most powerful stylists: Plato, Herodotus, (...) Thucydides and Demosthenes. (shrink)

At long last a comprehensive tool in English for a better understanding of the most basic terms in Aristotle's philosophy. A careful comparison of the original Greek, medieval and renaissance Latin translations and a reappraisal of English usage make the work a definitive source for the precise grasp of what has been the historical Aristotle as far as the documents permit one to judge. -- provided by the publisher.

Assuming it rational to treat other persons' probabilities as epistemically significant, how shall their judgements be weighted (Barnes [1998])? Several plausible methods exist, but theorems in classical psychometrics greatly reduce the importance of the problem. If scientists' judgements tend to be positively correlated, the difference between two randomly weighted composites shrinks as the number of judges rises. Since, for reasons such as representative coverage, minimizing bias, and avoiding elitism, we would rarely employ small numbers of judges (e.g. less than 10), (...) the difference between two weighting systems becomes negligible. Suggestions are made for quantifying verisimilitude, identifying 'types' of scientists or theories (taxometrics), inferring latent factors, and estimating reliability of pooled judgements. (shrink)

Digeser contends that our rich and varied practices of friendship multiply and moderate connections to politics. Along the way, she sets forth a series of ideals that appreciates friendship's many forms and its dynamic relationship to individuality, citizenship, political and legal institutions, and international relations.

Originally published in 1950, this book contains an edited version of the French text of Ernest Renan's 1871 work La réforme intellectuelle et morale, in which Renan makes suggestions intended to improve France in the wake of its defeat by Germany in the Franco-Prussian War. Charvet supplies a biographical note at the beginning of the book explaining Renan's life and opinions. This book will be of value to anyone with an interest in French history and the work of Renan.

The global workspace architecture is examined from an evolutionary perspective. It is argued that certain aspects of the theory are difficult to account for in terms of a sequence of evolutionary elaborations. These notably include distinct actors and audience members, and the lingua franca by which they communicate. An alternative metaphor of a ‘global arena’ is suggested, along with speculation on how this bottleneck of behavioural competition may have evolved toward a more sophisticated architecture, perhaps even a theatre . .
