Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

First published in 1999, this book brings together the extensive modern evidence for innate imitation in babies. Modern research has shown imitation to be a natural mechanism of learning and communication which deserves to be at centre stage in developmental psychology. Yet the very possibility of imitation in newborn humans has had a controversial history. Defining imitation has proved to be far from straightforward and scientific evidence for its existence in neonates is only now becoming accepted, despite more than a (...) century of enquiry. In this book, some of the world's foremost researchers on imitation and intellectual development review evidence for imitation in newborn babies. They discuss the development of imitation in infancy, in both normal and atypical populations and in comparison with other primate species, stressing the fundamental importance of imitation in human development, as a foundation of communication and a precursor to symbolic processes.

Should we regard Jennifer Lackey’s ‘Creationist Teacher’ as understanding evolution, even though she does not, given her religious convictions, believe its central claims? We think this question raises a range of important and unexplored questions about the relationship between understanding, factivity and belief. Our aim will be to diagnose this case in a principled way, and in doing so, to make some progress toward appreciating what objectual understanding—i.e., understanding a subject matter or body of information—demands of us. Here is the (...) plan. After some ground clearing in §1, §2 outlines and motivates a plausible working model—moderate factivity—for characterising the sense in which objectual understanding should be regarded as factive. §3 shows how the datum that we can understand false theories can, despite initial suggestions to the contrary, be assimilated straightforwardly within the moderate factivity model. §4 highlights how the inverse kind of case to that explored in §3—viz., a variant of Lackey’s creationist teacher case—poses special problems for moderate factivity. With reference to recent work on moral understanding by Hills, §5 proposes a solution to the problem, and §6 attempts to diagnose why it is that we might originally have been led to draw the wrong conclusion.

Protagoras, of all the ancient philosophers, has perhaps attracted the most interest in modern times. His saying ‘Man is the measure of all things’ caused Schiller to adopt him as the patron of the Oxford pragmatists, and has generally earned him the title of the first humanist. Yet the exact delineation of his philosophcal position remains a baffling task. Neumann, writing on Die Problematik des ‘Homo-mensura’ Satzes in 1938,2 concludes that no certainty whatever can be reached on the meaning of (...) the dictum, since ‘man’, ‘measure’, and ‘things’ are all ambiguous, nor can we tell which of the three is the predicate. The time is past when it was believed that a man's philosophy could be understood apart from the events of his life and the circumstances of his age: yet in the case of Protagoras the historical method of approach has hardly been attempted, although the impact of environment was perhaps more decisive in the formation of philosophical concepts in the Greek world than anywhere else. The reality about which the Greek philosopher spoke had three aspects: it was either the one universe of physics, or the political unity, or God. For example, the book of Heracleitus Περ φσεως was divided into three chapters or logoi, About the Whole, a political, and a theological. Neither physics nor theology supplies from its own subject-matter the form in which this reality was described. (shrink)

This volume of collected papers, with the accompanying essays by the editors, is the definitive source book for the work of this important experimental psychologist. Originally published in 1991, it offered previously inaccessible essays by Albert Michotte on phenomenal causality, phenomenal permanence, phenomenal reality, and perception and cognition. Within these four sections are the most significant and representative of the Belgian psychologist's research in the area of experimental phenomenology. Extremely insightful introductions by the editors are included that place the essays (...) in context. Michotte's ideas have played an important role in much research on the development of perception, and his work on social perception continues to be influential in social psychology. The book also includes some lesser-known aspects of his work that are equally important; for example, a remarkable set of articles on pictorial analysis. (shrink)

The achievements of the textile industry in Roman Britain are often underestimated as a result of the meagreness of our available evidence. The Edict on maximum prices issued by Diocletian in A.D. 301 shows that British capes commanded high prices on the markets of the Empire, and that in the late third century A.D. British rugs were the best in the world. In view of the competition from the traditional centres of rug manufacture in the East, this is an astonishing (...) achievement. (shrink)

The received translation and interpretation of many of the technical terms current in the textile industry of the Roman Empire are inaccurate, because lexicographers have either fought shy of being precise, or have thought that they recognized in the ancient world technical processes which originated at a much later date. The evidence is often equivocal or insufficient, but may still yield details that have been overlooked. The textile expression scutulatus, to take an example, deserves more attention than Blümner has devoted (...) to it. When it refers to the appearance of a garment, Lewis and Short, s.v. scutulatus, translate ‘diamond or lozenge-shaped, checkered’. It seems worth while to attempt a more precise translation, and, if possible, to estimate the significance in context of the goods so designated. (shrink)

This book intends to introduce readers to the work of Charles E. Butterworth, and thereby to introduce students to Medieval islamic political philosophy, of which Butterworth is one of the world's most prominent scholars. In a wider sense, the Festschrift introduces its readers to the current debates on Medieval islamic political philosophy, related as they are to the questions of the relationship between islam and Christianity, the Medieval to the Modern world, and reason and revelation. Butterworth's scholarship (...) spans six decades, primarily translating, editing, and interpreting the works of the Muslim political philosopher Alfarabi (d. 950) and Averroes (Ibn Rushd, d. 1198). He began his studies of Muslim political philosophy at a time when the Middle East and islam did not have the political salience they have acquired in more recent years. instead, Butterworth's reason for engaging with islam was rooted in the question of the relationship between reason and revelation. While one possible answer was pursued in the Christian, latin West, the islamic borderlands of Greek, Roman, and Muslim civilization offered another. By exploring Averroes, who provides the possibility of an Aristotelian-Islamic political philosophy, and Alfarabi, who pursues a Platonic-islamic political philosophy, Butterworth showed how islamic civilization provided a viable alternative to the theologico-political question reason v revelation, as well as serving as an inspiration to the latin West.

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

In this article I try to refute the so-called "libertarian" theory of free will, and to examine how our conclusion ought to modify our common attitudes of praise and blame. In attacking the libertarian view, I shall try to show that it cannot be consistently stated. That is, my dscussion will be an "analytic-philosophic" one. I shall neglect what I think is in practice an equally powerful method of attack on the libertarian: a challenge to state his theory in such (...) a way that it will fit in the modern biology and psychology, which are becoming increasingly physicalistic.
