The traditional verbal/nonverbal dichotomy is inadequate for completely describing cerebral lateralization. Musical functions are not necessarily mediated by the right hemisphere; evidence for a specialist left-hemisphere mechanism dedicated to the encoded speech signal is weakening, and the right hemisphere possesses considerable comprehensional powers. Right-hemisphere processing is often said to be characterized by holistic or gestalt apprehension, and face recognition may be mediated by this hemisphere partly because of these powers, partly because of the right hemisphere's involvement in emotional affect, and (...) possibly through the hypothesized existence of a specialist face processor or processors in the right. The latter hypothesis may, however, suffer the same fate as the one relating to a specialist encodedness processor for speech in the left. Verbal processing is largely the province of the left because of this hemisphere's possession of sequential, analytic, time-dependent mechanisms. Other distinctions are special cases of an analytic/holistic dichotomy. More fundamentally, however, the left hemisphere is characterized by its mediation of discriminations involving duration, temporal order, sequencing, and rhythm, at thesensory level, and especially at themotorlevel. Spatial aspects characterize the right, the mapping of exteroceptive body space, and the positions of fingers, limbs, and perhaps articulators, with respect to actual and target positions. Thus there is a continuum of function between the hemispheres, rather than a rigid dichotomy, the differences being quantitative rather than qualitative, of degree rather than of kind. (shrink)

Religious epistemology is widely regarded as being in a flourishing condition. It is true that some very sharp analytical work on religion has been produced by philosophers in the past few decades. But this work, for various cultural and historical reasons, has been kept within excessively narrow bounds, and the result is that the appearance of flourishing is to a considerable extent illusory. Here I discuss three important ways in which improvements to this situation might be made.

The ArgumentLevi ben Gerson, also known as Gersonides or Leo de Balneolis, was one of the most original Jewish thinkers of the Middle Ages, and he wrote on logic, philosophy, biblical exegesis, mathematics, and astronomy. During the last years of his life he maintained relations with the papal court of Clement VI (1342–52) at Avignon, and collaborated in the translation into Latin of hisSefer Tekhuna(Book of Astronomy). The object of this paper is to establish the main stages of the redaction (...) of the Hebrew and Latin extant versions of his astronomical work. Although Levi declares that the work was finished in 1328,1 argue that this text was the preliminary draft of the preserved one, most of which was composed after 1338. A thorough revision of the work was undertaken at an indeterminate date before 1344. It is also argued that the final form of the work was probably due to the request of solar and lunar tables made to Levi by “great and noble Christians” around 1332. (shrink)

The ArgumentA brief review of the Merton thesis shows that its restriction to England is arbitrary. An example from the historiography of modern physics suggests the possible payoff of an ecumenical Merton thesis and the means to explore it. A summary of the careers of men who practiced science literally in the church – men who built meridian lines in Italian cathedrals – indicates the range of social support of astronomical studies by Catholic institutions in the seventeenth and eighteenth centuries.

Durante los últimos años ha habido un creciente interés por parte de físicos y matemáticos en el estudio de problemas que surgen al tratar de comprender cuestiones de biología. Por otra parte los avances en las técnicas experimentales están permitiendo obtener una gran cantidad de información sobre los mecanismos que emplean las células en su funcionamiento. En este artículo se describen algunas líneas de investigación en matemáticas cuyo estudio ha sido motivado por el estudio de problemas biológicos.

In many places and times, and for many people, God's existence has been rather less than a clear fact. According to the hiddenness argument, this is actually a reason to suppose that it is not a fact at all. The hiddenness argument is a new argument for atheism that has come to prominence in philosophy over the past two decades. J. L. Schellenberg first developed the argument in 1993, and this book offers a short and vigorous statement of its central (...) claims and ideas. Logically sharp but so clear that anyone can understand, the book addresses little-discussed issues such as why it took so long for hiddenness reasoning to emerge in philosophy, and how the hiddenness problem is distinct from the problem of evil. It concludes with the fascinating thought that retiring the last of the personal gods might leave us nearer the beginning of religion than the end. (shrink)

Thucydides describes Antipho as ‘inferior to no one of his time in and more capable than any of initiating ideas and giving expression to them’. What does he mean here by? Does it refer to ability? or does it refer to courage and consistency of principle? and in either case how are we to relate this description of Antipho to Thucydides description of Nicias as less worthy than any other Greek of the historian's day to meet with the misfortunes that (...) he did?

J. L. Ackrill's work on Plato and Aristotle has had a considerable influence upon ancient philosophical studies in the late twentieth century. In his writings the rigour and clarity of contemporary analytic philosophy are brought to bear upon ancient thought; in many cases he has provided thefirst analytic treatment of a key issue. Gathered now in this volume are the best of Ackrill's essays on the two greatest philosophers of antiquity. With philosophical acuity and philological expertise he examines a wide (...) range of texts and topics--from ethics and logic to epistemology andmetaphysics--which continue to be in the focus of debate.

Aristotle is widely regarded as the greatest of all philosophers; indeed, he is traditionally referred to simply as `the philosopher'. Today, after more than two millennia, his arguments and ideas continue to stimulate philosophers and provoke them to controversy. In this book J.L. Ackrill conveys the force and excitement of Aristotle's philosophical investigations, thereby showing why contemporary philosophers still draw from him and return to him. He quotes extensively from Aristotle's works in his own notably clear English translation, and a (...) picture emerges of a lucid, lively, subtle and tough-minded thinker of astonishing range and penetration. Professor Ackrill identifies many striking connections between Aristotle's ideas and ideas in recent philosophy; he also raises philosophical questions of his own, and exemplifies the way in which Aristotle can still be argued with and learned from.
