On Power (De Potentia) is one of Aquinas's ''Disputed Questions'' (a systematic series of discussions of specific theological topics). It is a text which anyone with a serious interest in Aquinas's thinking will need to read. There is, however, no English translation of the De Potentia currently in print. A translation was published in 1932 under the auspices of the English Dominicans, but is now only available on a CD of translations of Aquineas coming from the InteLex Corporation. A new translation in book form is therefore highly desirable. However, the De Potentia is a very long work indeed (the 1932 translation fills three volumes), and a full translation would be a difficult publishing proposition as well as a challenge to any translator. Recognizing this fact, while wishing to make a solid English version of the De Potentia available, Fr. Richard Regan has produced this abridgement, which passes over some of the full text while retaining what seems most important when it comes to following the flow of Aquinas's thought.

Keckermann remarked of the sixteenth century, "never from the begin ning of the world was there a period so keen on logic, or in which more books on logic were produced and studies oflogic flourished more abun dantly than the period-in which we live. " 1 But despite the great profusion of books to which he refers, and despite the dominant position occupied by logic in the educational system of the fifteenth, sixteenth and seven teenth centuries, very little work has been done on the logic of the post medieval period. The only complete study is that of Risse, whose account, while historically exhaustive, pays little attention to the actual logical 2 doctrines discussed. Otherwise, one can tum to Vasoli for a study of humanism, to Munoz Delgado for scholastic logic in Spain, and to Gilbert and Randall for scientific method, but this still leaves vast areas untouched. In this book I cannot hope to remedy all the deficiencies of previous studies, for to survey the literature alone would take a life-time. As a result I have limited myself in various ways. In the first place, I con centrate only on those matters which are of particular interest to me, namely theories of meaning and reference, and formal logic."

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."

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.

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.

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."

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."

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.

This is the first great commentary in the Western European tradition of expounding Aristotle's Metaphysics. Dated about 1238, this work by Richard Rufus of Cornwall is a major contribution to the history of Western philosophy and the study of Aristotle. No future account of thirteenth-century metaphysics will be able to ignore its contribution. Rufus addresses questions as diverse as 'what is truth?', 'are there many eternal truths?', 'what is prime matter?', and 'how do corruptible and incorruptible substances differ?'. Rufus' views on the nature of truth were strongly influenced by Anselm, while his treatment of the problem of the eternal truths was influenced by his contemporary, Robert Grosseteste. But his views on prime matter owe more to his reading of Averroes and Averroes' understanding of the Aristotelian tradition, as well as to the influence of Augustine. Even so, while deeply indebted to the Aristotelian tradition, Rufus displays an independence and originality of thought throughout the Scriptum. The Scriptum's exposition of Aristotle and its exciting questions date from about 35 years before Thomas Aquinas wrote his commentary on the Metaphysics. Its publication will prompt a re-evaluation of the development of metaphysics in the Latin West. As the copious notes to this edition indicate, it was a very influential work that had a significant impact on the views of the two most popular early Aristotle commentators, Adam Buckfield and Albert the Great.

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.

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.

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.

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.
