Medieval Jewish intellectuals living in Muslim and Christian lands were strongly concerned to recover what they regarded as a 'lost' Jewish philosophical tradition. As part of this project they transmitted and produced many philosophical and scientific works and commentaries, as well as philosophical commentary on scripture, in Judaeo-Arabic and Hebrew, the principal literary languages of medieval Jewry. This volume presents new or revised translations of seven prominent medieval Jewish rationalists: Saadia Gaon, Solomon ibn Gabirol, Moses Maimonides, Isaac Albalag, Moses of Narbonne, Levi Gersonides, Hasdai Crescas and Joseph Albo - including, for the first time in English, the complete Falaquera abridgement of Gabirol's Source of Life. These works range over topics that are both theological (e.g. the creation of the world) and philosophical (e.g. determinism and free choice), but they are characterized by two overarching principles: the unity of truth, and its accessibility to human reason.

1. 1. INTRODUCTORY REMARKS At the end ofthe 19th century, when the discipline called psychology 1 is said to have become "independent" , attention began to be focused towards nominalistic philosophy from a point of view that can be called psychological. At that time, Vienna, the capital of the Austro- Hungarian Dual Monarchy, was a center for several disciplines. It is no wonder that it was there that the research conceming the psychological themes of William Ockham and other nominalists began. Karl Wemer (1821-1888), a Catholic, neo-scholastic scholar, professor of New Testament studies at the Univers?ty of Vienna (1870), and a member ofthe Imperial Academy of Sciences (1874), seems to have planned a history of medieval psychology. However, only fragments of it were printed, among them the following articles: 'Der A verroismus in der christlich-peripatetischen Psychologie des sp?teren Mittelalters' (1881), 'Die nominalisirende Psychologie der Scholastik des sp?teren Mittelalters' (1881) and 'Die augustinische Psychologie in ihrer mittelalterlich-scholastischen Einkleidung und Gestaltung' (1882). 2 Wemer deals especially with Ockham's 1 See Kusch 1995 and 1999. 2 Pluta 1987, 12-13. See Wemer 1881a, 1881b, 1882. (Those three texts were republished in 1964 under the name Psychologie des Mittelalters. ) Prior to those books, Wemer had written about William of Auvergne's, Bonaventure's, John Duns Scotus's and Roger 1 2 CHAPTERONE psychology, among other things, in the second of these articles.

The study features the five most important and most efficacious themes of Western spirituality in their ancient historical origins and in their unfolding up to early modernity: Divine names, Microkosmos-Makrokosmos, theories of creation, the idea of spiritual spaces, and the concepts of eschatological history.

This book presents novel formalizations of three of the most important medieval logical theories: supposition, consequence and obligations. In an additional fourth part, an in-depth analysis of the concept of formalization is presented a crucial concept in the current logical panorama, which as such receives surprisingly little attention.

Although formalizations of medieval logical theories have been proposed earlier in the literature, the formalizations presented here are all based on innovative vantage points: supposition theories as algorithmic hermeneutics, theories of consequence analyzed with tools borrowed from model-theory and two-dimensional semantics, and obligations as logical games. For this reason, this is perhaps the first time that these medieval logical theories are made fully accessible to the modern philosopher and logician who wishes to obtain a better grasp of them, but who has always been held back by the lack of appropriate translations into modern terms.

Moreover, the book offers a reflection on the very nature of logic, a reflection that is prompted by the comparisons between medieval and modern logic, their similarities and dissimilarities. It is thus a contribution not only to the history of logic, but also to the philosophy of logic, the philosophy of language and semantics.

The analysis of medieval logic is also relevant for the modern philosopher and logician in that, being the unifying methodology used across all disciplines at that time, logic really provided unity to science. It thus presents a unified model of scientific investigation, where logic plays the aggregating role.

Theories about the ontological structure of the world have generally been described in informal, intuitive terms. This book offers an account of the general features and methodology of formal ontology. The book defends conceptual realism as the best system to adopt based on a logic of natural kinds. By formally reconstructing an intuitive, informal ontological scheme as a formal ontology we can better determine the consistency and adequacy of that scheme.

Daniel Schwartz examines the views on friendship of the great medieval philosopher Thomas Aquinas. For Aquinas friendship is the ideal type of relationship that rational beings should cultivate. Schwartz argues that Aquinas fundamentally revises some of the main features of Aristotle's paradigmatic account of friendship so as to accommodate the case of friendship between radically unequal beings: man and God. As a result, Aquinas presents a broader view of friendship than Aristotle's, allowing for a higher extent of disagreement. lack of mutual understanding, and inequality between friends.

This book offers a revisionary account of key epistemological concepts and doctrines of St Thomas Aquinas, particularly his concept of scientia (science), and proposes an interpretation of the purpose and composition of Aquinas's most mature and influential work, the Summa theologiae, which presents the scientia of sacred doctrine, i.e. Christian theology. Contrary to the standard interpretation of it as a work for neophytes in theology, Jenkins argues that it is in fact a pedagogical work intended as the culmination of philosophical and theological studies of very gifted students. Jenkins considers our knowledge of the principles of a science. He argues that rational assent to the principles of sacred doctrine, the articles of faith, is due to the influence of grace on one's cognitive powers, because of which one is able immediately to apprehend these propositions as divinely revealed. His study will be of interest to readers in philosophy, theology and medieval studies.

Abelard was one of the greatest thinkers of the twelfth century, a man of towering brilliance and arrogance, but his poetic works written late in life for his wife Heloise and son Astrolabe reveal a different and more humble man. In the Planctus and the Carmen ad Astralabium we see a man newly coming to terms with the life around him, expressing a simple but heartfelt piety, raging against social injustices and the exploitation of the poor, and re-evaluating the importance of rhetoric and education. Most significantly, we find a man struggling to comprehend, through poems written to the wife and child he abandoned, the divine mysteries of love, relationships and family.

Studies of medieval Biblical interpretation usually focus on the printed literature, neglecting the vast majority of relevant works. Timothy Bellamah offers a groundbreaking examination of the exegesis of William of Alton, a thirteenth-century Dominican regent master at Paris whose commentaries have never previously appeared in print.
As a near contemporary of Hugh of St. Cher, Bonaventure, Albert the Great, and Thomas Aquinas, William was an important representative of university exegesis at a time of rapidly changing methods and remarkable intellectual development. His commentaries are valuable resources for understanding Biblical study of the thirteenth century, in the schoolroom and in the pulpit. Yet study of William's work has been impeded by the dubious authenticity of numerous commentaries questionably attributed to him over the centuries.
Bellamah addresses these complex problems by unearthing evidence of authorship in each commentary's style and methodology. This inquiry employs the traits of William's commentaries as criteria for constituting a list of works that can be reliably attributed to him, which, in turn, provides a crucial basis for studying his exegesis. William was a man of his time, but even more than his contemporaries he was deeply interested in history and the literal sense, which he understood to be the intention of Scripture's authors, divine and human. He took a keen interest in Biblical history and put to use a wide array of procedures for textual, linguistic, and rhetorical analysis. At the same time, he remained aware of the spiritual senses and the diverse elements of the exegetical and theological tradition in which he stood.

A celebration of Montaigne, the most enjoyable and yet profound of all Renaissance writers.
In the year 1570, at the age of thirty-seven, Michel de Montaigne gave up his job as a magistrate and retired to his chateau to brood on the deaths of his best friend, his father, his brother, and his firstborn child. But finding his mind agitated, rather than settled, by idleness, Montaigne began to write, giving birth to the "Essays"--a series of reflections on life in all its profundity and triviality. And, gradually, over the course of his writing, Montaigne turned from a philosophy of death to a philosophy of life, finding consolation in the most unlikely places--the touch of a hand, the smell of his doublet, the flavor of his wine, and the playfulness of his cat.

Maimonides' Guide for the Perplexed is one of the most discussed books in Jewish history. Over 800 years after the author's death it remains disputed with readers seeking secret philosophical messages behind its explicit teaching, a quest fueled partly by Maimonides' own statement that certain parts of the Guide are based upon ideas that conflict with other parts. Many who adhere to an 'esoteric' reading of the Guide profess to find these contradictions in Maimonides' metaphysical beliefs. Through close readings of the Guide, this book addresses the major debates surrounding its secret doctrine. It argues that perceived contradictions in Maimonides' accounts of creation and divine attributes can be squared by paying attention to the various ways in which he presented his arguments. Furthermore, it shows how a coherent theological view can emerge from the many layers of the Guide. But Maimonides' clear declaration that certain matters must be hidden from the masses cannot be ignored and the kind of inconsistency that is peculiar to the Guide requires another explanation. It is found in the purpose Maimonides assigns to the Guide scriptural exegesis. Ezekiel's Account of the Chariot, treated in one of the most laconic sections of the Guide, is the subject of the final chapters. They offer a detailed exposition of Maimonides' interpretation, the deepest ''secret of the Torah, '' which, in Maimonides' works, shares its name with metaphysics. By connecting the vision with currents in the wider Islamic world, the chapters show how Maimonides devised a new method of presentation in order to imitate scripture's multi-layered manner of communication. He updated what he took to be the correct interpretation of scripture by writing it in a work appropriate for his own time and to do so he had to keep the Torah's most hidden secrets.

During the seventies, there was a revival of systematic philosophy in general and of ontology in particular. At the same time, especially in Anglo-Saxon thinking, systematic philosophy interacted very creatively with the history of medieval philosophy. It seems to us that the work of John Duns Scotus (1266-1308) could substantially benefit these develop ments. Not only this, but his works cries out to be developed across the whole spectrum of theology -that science which, in the Middle Ages, ruled all others ('regina scientiarum'). This book is the outcome of several years of scholarship and friend ship during which, guided by Dr. A. Vos, we have studied the work of Scotus. Our research group is connected to the Theological Faculty of Utrecht and to the Dutch Franciscan Study Centre (Stichting Francis caans Studiecentrum). This study presents a translation and commentary of Lectura I 39, which, in our view, is noteable as one of the key texts in the history of systematic theology and philosophy. In this book we have used specialist language and argumentation, but at the same time have taken pains to make it useful to a circle of in terested readers wider than simply that of those well-versed in medieval scholasticism. In this way, we hope to present the difficult but instruc tive work of the 'subtle master' ('doctor subtilis') in such a way as to make it attractive to other scholars and students in theology and philoso phy."

The Latin texts collected by Leon Baudry present the late fifteenth century debate at the University of Louvain over the truth-value of proposi tions about future contingent events, a subject of perennial interest in phil osophy. The theologians held fast to divine predetermination, and the Aristotelians in the Arts Faculty supported the doctrine of free choice based on indeterminism. Although the issues in the debate are still argued in philosophy, this rich collection of the theories and arguments has been neglected. Peter de Rivo and Henry de Zomeren, the principal antagonists, are cited in the recent literature, but only on the basis of slight, mostly second-hand information. The full collection of texts has never before been translated into English (or any other modern language), leaving them inaccessible to the majority of students, or any others who are not equipped to work their way through 450 pages of fifteenth-century scholastic Latin. Apart from their philosophical significance, the texts shed light on late scholastic methods in teaching and disputation, on university politics of the period in relation to the Vatican, the Court of the Duke of Burgundy, and the faculties of other great universities, and on legal procedures both secular and ecclesiastical. The human drama that develops as the debate proceeds should hold the interest of even the non-specialist."

Andinmy haste, I said: "Allmenare Liars" 1 -Psalms 116:11 The Original Lie Philosophical analysis often reveals and seldom solves paradoxes. To quote Stephen Read: A paradox arises when an unacceptable conclusion is supported by a plausible argument from apparently acceptable premises. [...] So three di?erent reactions to the paradoxes are possible: to show that the r- soning is fallacious; or that the premises are not true after all; or that 2 the conclusion can in fact be accepted. There are sometimes elaborate ways to endorse a paradoxical conc- sion. One might be prepared to concede that indeed there are a number of grains that make a heap, but no possibility to know this number. However, some paradoxes are more threatening than others; showing the conclusiontobeacceptableisnotaseriousoption,iftheacceptanceleads to triviality. Among semantic paradoxes, the Liar (in any of its versions) 3 o?ers as its conclusion a bullet no one would be willing to bite. One of the most famous versions of the Liar Paradox was proposed by Epimenides, though its attribution to the Cretan poet and philosopher has only a relatively recent history. It seems indeed that Epimenides was mentioned neither in ancient nor in medieval treatments of the Liar 1 Jewish Publication Society translation. 2 Read [1].

the demise of the logical positivism programme. The answers given to these qu- tions have deepened the already existing gap between philosophy and the history and practice of science. While the positivists argued for a spontaneous, steady and continuous growth of scientific knowledge the post-positivists make a strong case for a fundamental discontinuity in the development of science which can only be explained by extrascientific factors. The political, social and cultural environment, the argument goes on, determine both the questions and the terms in which they should be answered. Accordingly, the sociological and historical interpretation - volves in fact two kinds of discontinuity which are closely related: the discontinuity of science as such and the discontinuity of the more inclusive political and social context of its development. More precisely it explains the discontinuity of the former by the discontinuity of the latter subordinating in effect the history of science to the wider political and social history. The underlying idea is that each historical and - cial context generates scientific and philosophical questions of its own. From this point of view the question surrounding the nature of knowledge and its development are entirely new topics typical of the twentieth-century social context reflecting both the level and the scale of the development of science.

This reissue was first published in 1978. Anthony Kenny, one of the most distinguished philosophers in England, explores the notion of responsibility and the precise place of the mental element in criminal actions. Bringing the insights of recent philosophy of mind to bear on contemporary developments in criminal law, he writes with the general reader in mind, no specialist training in philosophy being necessary to appreciate his argument. Kenny shows that abstract distinctions drawn by analytic philosophers are relevant to decisions in matters of life and death, and illustrates the philosophical argument throughout by reference to actual legal cases. The topics he covers are of wide general interest and include: mens rea and mental health, strict liability, freedom and determinism, duress and necessity, intoxication and irresistible impulse, intention and purpose, murder and rape, punishment and deterrence, witchcraft and supernatural beliefs.

Central topics in medieval logic are here treated in a way that is congenial to the modern reader, without compromising historical reliability. The achievements of medieval logic are made available to a wider philosophical public then the medievalists themselves. The three genres of logica moderna arising in a later Middle Ages are covered: obligations, insolubles and consequences - the first time these have been treated in such a unified way. The articles on obligations look at the role of logical consistence in medieval disputation techniques. Those on insolubles concentrate on medieval solutions to the Liar Paradox. There is also a systematic account of how medieval authors described the logical content of an inference, and how they thought that the validity of an inference could be guaranteed.

Modern mechanics was forged in the seventeenth century from materials inherited from Antiquity and transformed in the period from the Middle Ages through to the sixteenth century. These materials were transmitted through a number of textual traditions and within several disciplines and practices, including ancient and medieval natural philosophy, statics, the theory and design of machines, and mathematics.

This volume deals with a variety of moments in the history of mechanics when conflicts arose within one textual tradition, between different traditions, or between textual traditions and the wider world of practice. Its purpose is to show how the accommodations sometimes made in the course of these conflicts ultimately contributed to the emergence of modern mechanics.

The first part of the volume is concerned with ancient mechanics and its transformations in the Middle Ages; the second part with the reappropriation of ancient mechanics and especially with the reception of the Pseudo-Aristotelian Mechanica in the Renaissance; and the third and final part, with early-modern mechanics in specific social, national, and institutional contexts.

Anselm of Canterbury (1033-1109 CE), in his work Proslogion, originated the "ontological argument" for God's existence, famously arguing that "something than which nothing greater can be conceived," which he identifies with God, must actually exist, for otherwise something greater could indeed be conceived. Some commentators have claimed that although Anselm may not have been conscious of the fact, the Proslogion as well as his Reply to Gaunilo contains passages that constitute a second independent proof: a "modal ontological argument" that concerns the supposed logical necessity of God's existence. Other commentators disagree, countering that the alleged second argument does not stand on its own but presupposes the conclusion of the first. Anselm's Other Argument stakes an original claim in this debate, and takes it further. There is a second a priori argument in Anselm (specifically in the Reply), A. D. Smith contends, but it is not the modal argument past scholars have identified. This second argument surfaces in a number of forms, though always turning on certain deep, interrelated metaphysical issues. It is this form of argument that in fact underlies several of the passages which have been misconstrued as statements of the modal argument. In a book that combines historical research with rigorous philosophical analysis, Smith discusses this argument in detail, finally defending a modification of it that is implicit in Anselm. This "other argument" bears a striking resemblance to one that Duns Scotus would later employ.

Adelard of Bath was one of the most colourful personalities of the Middle Ages. He travelled to the Crusader kingdoms, to Sicily and south Italy, and translated texts on astronomy, astrology and magic from Arabic into Latin. He acquired a lasting reputation as a pioneering mathematician, and he was a gifted teacher. He addressed one of these works, on cosmology and the astrolabe, to the future King Henry II, and it is in the context of the education of the nobility that the three works edited in this book are to be viewed. Adelard meant them to be both entertaining and instructive. They deal with all kinds of topics, from the nature of the soul to the cause of earthquakes, from the effects of music to how to train a hawk. A preface provides the results of research on Adelard's life and work.
