As originally planned this volume was meant to cover a somewhat wider scope than, in fact, it has turned out to do. When, in rg68, I initially conceived of preparing it, it was proposed to deal with several aspects of early modern scepticism, in addition to the fortuna of the Academica, and to publish various loosely related pieces under the title of 'Studies in the History of Early Modern Scepticism. ' Thereby, I foresaw that I would exhaust my knowledge of the subject and would then be able to turn my attention to other matters. In initiating my research on this topic, however, I soon found that there remained a much greater bulk of material to study than could possibly be dealt with between the covers of the single modest volume which I envisioned. My proposed section on Cicero's Academica was to cover between 50 and 75 pages in the original plan. It soon became apparent, however, especially after Joannes Rosa's hitherto unstudied commentary on Cicero's work was uncovered, that this material would have to be treated at a much greater length than I had foreseen. The present volume is the result of this expanded investigation. The monograph which has come from this alteration in plans has, I think, the virtues of continuity and cohesive ness and one hopes that these advantages offset the benefits of a broader scope which were sacrificed."

Abelard is one of the foremost protagonists of the "twelfth-century Renaissance." He 'picks up the baton' from Boethius resuming the activity of commenting on Aristotle's works. The present book focuses on the logical-grammatical analysis of natural language, which for Abelard is a fragment of "scientific Latin." Tools of modern categorial grammar are employed to clarify many of the problems raised by historiography (such as meaning, abstract entities and universals). Among the merits of the volume is the fact that it has enlightened the radical interplay between the traditions of Aristotle's and Priscian's commentators and, in this context, Abelard's peculiar role in exploring a new field of linguistic inquiry. An ample analysis of grammatical sources and critical literature allows to evaluate the progress which is at the basis of the forthcoming terministic logic. The book is aimed at scholars of medieval philosophy as well as historians of logic and linguistics.

1.1. Why the Ontology 0/ Time? The intention that directs this research consists in an attempt to provide a herme- neutic analysis ofthe drastic changes, which have occurred in 20th century philoso- phy, in identifying the new role ascribed to the subject of time and temporality within the scope ofontology. Afterthe fundamental works ofE. Husserl, M. Heid- egger. P. Rica:ur. and E. Levinas, it has been understood that the traditional issue (which could be traced back to Parmenides) between being and time, between the eternal and the transient (or historical), must once again be re-examined. Time it- self is recognized now as the deepest ground of ontological inquiry, which sets in motion the entire system offundamental philosophical concepts. This does not mean, of course, that our understanding of time did not change in the course of these fundamental transformations. In order to comprehend the new role oftime within "first philosophy," the concept o/time itselfis to be subjected to a careful investigation and interpretation. It is necessary to come back to Aristotle's quest ions in Physics IV: In what sense can we ascribe being to time itself. and what is the "nature" of time as (a) being'! In other words, to understand the role oftime within the scope of ontology means to develop simultaneously the ontology 0/ time. This is what the title ofthis work intends to designate. Moreover, my aim is to dem- onstrate that in a defmite sense the postmodern onto-Iogy is chrono-Iogy.

In January 1998 leading scholars from Europe, the United States, and Israel in the fields of medieval encyclopedias (Arabic, Latin and Hebrew) and medieval Jewish philosophy and science gathered together at Bar-Ilan University in Ramat-Gan, Israel, for an international conference on medieval Hebrew encyclopedias of science and philosophy. The primary purpose of the conference was to explore and define the structure, sources, nature, and characteristics of the medieval Hebrew encyclopedias of science and philosophy. This book, the first to devote itself to the medieval Hebrew encyclopedias of science and philosophy, contains revised versions of the papers that were prepared for this conference. This volume also includes an annotated translation of Moritz Steinschneider's groundbreaking discussion of this subject in his Die hebraeischen Ubersetzungen. The Medieval Hebrew Encyclopedias of Science and Philosophy will be of particular interest to students of medieval philosophy and science, Jewish intellectual history, the history of ideas, and pre-modern Western encyclopedias."

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.

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.

Pauliina Remes and Juha Sihvola In the course of history, philosophers have given an impressive variety of answers to the question, "What is self?" Some of them have even argued that there is no such thing at all. This volume explores the various ways in which selfhood was approached and conceptualised in antiquity. How did the ancients understand what it is that I am, fundamentally, as an acting and affected subject, interpreting the world around me, being distinct from others like and unlike me? The authors hi- light the attempts in ancient philosophical sources to grasp the evasive character of the specifically human presence in the world. They also describe how the ancient philosophers understood human agents as capable of causing changes and being affected in and by the world. Attention will be paid to the various ways in which the ancients conceived of human beings as subjects of reasoning and action, as well as responsible individuals in the moral sphere and in their relations to other people. The themes of persistence, identity, self-examination and self-improvement recur in many of these essays. The articles of the collection combine systematic and historical approaches to ancient sources that range from Socrates to Plotinus and Augustine.

This collection represents the first historical survey focusing on the notion of consciousness. It approaches consciousness through its constitutive aspects, such as subjectivity, reflexivity, intentionality and selfhood. Covering discussions from ancient philosophy all the way to contemporary debates, the book enriches current systematic debates by uncovering historical roots of the notion of consciousness.

Sense perception is one of the classical themes in philosophy. It is traditionally considered a necessary preamble to many important topics, such as the mind-body relationship, consciousness, knowledge, and skepticism. Perception is also a phenomenon which itself raises philosophical questions, such as what is perceptible, what the content of perception is, whether this content is conceptual and how perception is related to epistemic attitudes. While the philosophy of mind and philosophical psychology are the main areas in which perception is dealt with in contemporary philosophy, it is also discussed in the theory of knowledge, cognitive science, philosophical aesthetics and metaphysics. In recent years, the rich tradition of various philosophical theories of perception has been increasingly studied by scholars of the history of philosophy of mind.

The aim of this collection is to shed light on the developments in the theories of sense-perception in medieval Arabic and Latin philosophy, their ancient background and traditional and new themes in early modern thought. Particular attention is paid to the philosophically significant parts of the theories. The articles concentrate on the so-called external senses and related themes. Many of the central ideas are discussed, although the collection is also meant to shed light on less studied subjects.

Thomas Aquinas wrote a text later known as Quaestio de attributis and ordered it inserted in a precise location of his Commentary on the Sentences of Peter Lombard more than a decade after composing this work. Aquinas assigned exceptional importance to this text, in which he confronts the debate on the issue of the divine attributes that swept the most important centres of learning in 13th Century Europe and examines the answers given to the problem by the representatives of the four mainstream schools of his time: the Greek mystic Dionysius Areopagita, the Latin Saint Anselm of Canterbury, the Jewish rabbi Moses Maimonides and the Muslim philosopher Ibn Sina.
This in-depth study of Thomas Aquinas Quaestio de attributis (In I Sent., d. 2, q. 1, a. 3) binds together the findings of previous research on the unique history of this text by reconstructing the historical circumstances surrounding its composition, shows that the Quaestio contains Aquinas final answer to the dispute on the divine attributes, and thoroughly examines his interpretation of Maimonides position on the issue of the knowledge of God by analysing this and other texts related to it chronologically and doctrinally. The examination of the Quaestio reveals the background of Thomas Aquinas renewed interest in Maimonides position on the issue and brings to light elements of Aquinas interpretation that are absent from his earlier references to Maimonides.

Moreover, the chronological and doctrinal connection of the Quaestio de attributis to other Thomistic works with explicit references to Maimonides enables a reconstruction of his comprehensive approach to Maimonides teaching on the possibility and extent of the knowledge of God in the Guide of the Perplexed and highlights the place of Maimonides philosophical teachings in Thomas own thought in issues like "Being" as the proper name of God, the multiplicity of the divine names, the beatific vision in the afterlife, the causes that prevent the instruction of the multitude in divine matters and the role of faith and prophecy in the acquisition of the true knowledge of God in this life.
The last chapter examines the reasons behind Aquinas silencing of Maimonides name when introducing his Five Ways for the knowledge of the existence of God, in spite of the evident relation between these and Maimonides Four Speculations. The study is completed with an extensive appendix that includes the text of the Quaestio de attributis with an English translation and the critical edition of several chapters of the 13th Century Latin translation of the Guide of the Perplexed known as Dux neutrorum."

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.

A number of Jewish philosophers active in Spain and Italy in the second half of the 15th century (Abraham Bibago, Baruch Ibn Ya'ish, Abraham Shalom, Eli Habillo, Judah Messer Leon) wrote Hebrew commentaries and questions on Aristotle. In these works, they reproduced the techniques and terminology of Late-Medieval Latin Scholasticism, and quoted and discussed Latin texts (by Albert the Great, Thomas Aquinas, William of Ockham, John Duns Scotus, and other authors) about logic, physics, metaphysics, and ethics. All of these works are still unpublished, and they have not yet been either studied, or translated in modern languages.

The aim of this book is to give an idea of the extent and character of this hitherto neglected "Hebrew Scholasticism." After a general historical introduction to this phenomenon, and bio-bibliographical surveys of these philosophers, the book gives complete or partial annotated English translations of the most significant Hebrew Scholastical works. It includes also critical editions of some parts of these texts, and a Latin-Hebrew glossary of Scholastical technical terms.

This book deals with the internal senses, the mind/body problem and other problems associated with the concept of mind as it developed from Avicenna to the medical Enlightenment. The book collects essays from scholars in this promising field of research. It brings together scholars working on the same issues in the Arabic, Jewish and Western philosophical traditions. This collection opens up new and interesting perspectives.

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.

This volume explores key aspects of the transmission of learning and the transformation of thought from the late Middle Ages to the early modern period. The topics dealt with include metaphysics as a science, the rise of probabilistic modality, freedom of the human will, as well as the role and validity of logical reasoning in speculative theology. The volume will be of interest to scholars who work on medieval and early modern philosophy, theology, and intellectual history.

This volume provides the first comprehensive treatment of the central topics in the contemporary philosophy of religion from a Thomist point of view. It focuses on central themes, including religious knowledge, language, science, evil, morality, human nature, God and religious diversity. It should prove valuable to students and faculty in philosophy of religion and theology, who are looking for an introduction to the Thomist tradition.

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.

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."

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.

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].

This book examines the potential of conducting studies in comparative hagiology, through parallel literary and historical analyses of spiritual life writings pertaining to distinct religious contexts. In particular, it focuses on a comparative analysis of the early sources on the medieval Christian Saint Francis of Assisi (1182-1226) and the Tibetan Buddhist Milarepa (c. 1052-1135), up to and including the so-called 'standard versions' of their life stories written by Bonaventure of Bagnoregio (1221-1274) and Tsangnyoen Heruka (1452-1507) respectively. The book thus demonstrates how in the social and religious contexts of both 1200s Italy and 1400s Tibet, narratives of the lives, deeds and teachings of two individuals recognized as spiritual champions were seen as the most effective means to promote spiritual, doctrinal and political agendas. Therefore, as well being highly relevant to those studying hagiographical sources, this book will be of interest to scholars working across the fields of religion and the comparative study of religious phenomena, as well as history and literature in the pre-modern period.

Abu'l-Barakat is a renowned philosopher of the Arabic-Jewish milieu who composed in his magnum opus the Kitab al-Mu'tabar, a comprehensive metaphysics which challenged the accepted notions of the traditional metaphysical philosophy. 'Abu'l-Barakat al-Baghdadi's Metaphysical Philosophy' examines the novel philosophical conceptions of the first book of the Metaphysics of the Kitab al-Mu'tabar. The aim is to present a developed conception of Abu'l-Barakat's systematic metaphysics. This is accomplished by following the order of topics discussed, while translating the relevant passages. These different topics comprise stages of cognition that move from an analysis of time, creation and causality to the conception of a higher spiritual realm of mental entities and a conception of God as the First Knower and Teacher. The epistemological and ontological conceptions are analyzed at each culminating stage. 'Abu'l-Barakat al-Baghdadi's Metaphysical Philosophy' analyzes vast portions of the metaphysical study for the first time. The book will thus be a valuable resource for all those seeking an original and broad metaphysics, and for students and scholars of Jewish and Islamic Philosophy. Furthermore, it is of importance for those seeking a metaphysics related to scientific theories and those interested in the history of science and metaphysics.

Abu'l-Barakat is often considered one of the most comprehensive philosophers of the Arabic-Jewish milieu in the medieval age. His extensive and unique philosophical theories, especially his theories in the particular sciences, were seen as a major challenge for the traditional conceptions of the Aristotelian school of thought during and after this period. 'Abu'l-Barakat al-Baghdadi's Scientific Philosophy' explores the core material of Abu'l-Barakat's scientific studies, found in his magnum opus the Kitab al-Mu'tabar. The book then locates these scientific theories within Abu'l-Barakat's philosophy more widely. Whilst providing a comprehensive critique of ancient philosophy, including the work of Aristotle, certain affinities between Abu'l-Barakat's work and that of more modern scientific conceptions are also examined. Containing vast amounts of previously untranslated text, 'Abu'l-Barakat al-Baghdadi's Scientific Philosophy' sheds new light on the philosopher's scientific theories, particularly with regards to his logical conceptions. For this reason, the book will be a valuable resource for students and scholars of Jewish and Islamic Philosophy, whilst the scientific material will appeal to those studying the history of science.

This book presents an edition of the Questiones super libro De Animalibus Aristotelis, a work by one of the greatest philosophers and physicians of the 13th century, Peter of Spain (later Pope John XXI, 1205-1277). He took as the basis for his work the translation from the Arabic made in Toledo around 1220 by Michael Scotus which included three important Aristotelian treatises. Preceding the critical edition, Dr Navarro offers an introduction to the person and works of Peter of Spain, the intellectual context of the 13th century characterized by Scholasticism and an Aristotelian Renaissance, and a short analysis of the linguistics and form of the Questiones. She also analyses the sources on which Peter drew, Greco-Latin, Arabo-Jewish and, of course, late antique and medieval treatises, showing that the text was not exclusively zoological in nature, but discusses important medical and philosophical topics, illustrating his extensive knowledge of both the Aristotelian corpus and 13th-century medicine. The text (divided into XIX books) is not a mere commentary about animals, but rather, as the title shows, a collection of questions in the Salernitan manner, the use of which was considered most appropriate for analysis and communication in the medieval scientific community to which Peter of Spain belonged. Alongside methodological and zoological problems, Peter of Spain discusses important questions disputed among the scholars of the period, including the location, hierarchy, motion, function and parts of the principal organs, the five senses, and many other medical issues such as reproduction, illnesses, or growth. Finally Dr Navarro includes a glossary that contains proper names (mainly those of the authorities and sources quoted by Petrus Hispanus), animal names (and their parts and substances), and the names of plants, metals, and the like.
