The word "modem" in the title of this book refers primarily to post-medieval discussions, but it also hints at those medieval mo dal theories which were considered modem in contradistinction to ancient conceptions and which in different ways influenced philosophical discussions during the early modem period. The me dieval developments are investigated in the opening paper, 'The Foundations of Modality and Conceivability in Descartes and His Predecessors', by Lilli Alanen and Simo Knuuttila. Boethius's works from the early sixth century belonged to the sources from which early medieval thinkers obtained their knowledge of ancient thought. They offered extensive discus sions of traditional modal conceptions the basic forms of which were: (1) the paradigm of possibility as a potency striving to realize itself; (2) the "statistical" interpretation of modal no tions where necessity means actuality in all relevant cases or omnitemporal actuality, possibility means actuality in some rel evant cases or sometimes, and impossibility means omnitemporal non-actuality; and (3) the "logical" definition of possibility as something which, being assumed, results in nothing contradic tory. Boethius accepted the Aristotelian view according to which total possibilities in the first sense must prove their met tle through actualization and possibilities in the third sense are assumed to be realized in our actual history. On these presump tions, all of the above-mentioned ancient paradigms imply the Principle of Plenitude according to which no genuine possibility remains unrealized.

The last twenty years have seen remarkable developments in our understanding of how the ancient Greek thinkers handled the general concept of being and its several varieties. The most general examination of the meaning of the Greek verb 'esti'/'einai'/'on' both in common usage and in the philosophical literature has been presented by Charles H. Kahn, most extensively in his 1973 book The Verb 'Be' in Ancient Greek. These discussions are summarized in Kahn's contribution to this volume. By and large, they show that conceptual schemes by means of which philosophers have recently approached Greek thought have not been very well suited to the way the concept of being was actually used by the ancients. For one thing, being in the sense of existence played a very small role in Greek thinking according to Kahn. Even more importantly, Kahn has argued that Frege and Russell's thesis that verbs for being, such as 'esti', are multiply ambiguous is ill suited for the purpose of appreciating the actual conceptual assumptions of the Greek thinkers. Frege and Russell claimed that a verb like 'is' or'esti' is ambiguous between the 'is' of identity, the 'is' of existence, the copulative 'is', and the generic 'is' (the 'is' of class-inclusion). At least a couple of generations of scholars have relied on this thesis and fre quently criticized sundry ancients for confusing these different senses of 'esti' with each other.

Many fourteenth-century logicians took affirmative propositions to maintain that the subject term and the predicate term stand or supposit for the same. This is called the identity theory of predication by historians and praedicatio identica by Paul of Venice and others. The identity theory of predication was an important part of early fourteenth-century Trinitarian discussions as well, but what was called praedicatio identica by Duns Scotus and his followers in this context was something different. After some remarks on Scotus’s view and its background, I shall analyse Adam Wodeham’s explanation of Scotus’s praedicatio identica and how he understood the assumptions pertaining to supposition in the Scotist approach. I also describe Wodeham’s own solution to Trinitarian sophisms, which did not deviate from the identity theory of predication.

In this article, I shall consider medieval discussions of the principles of Aristotelian syllogistic which were called the dictum de omni et nullo and the expository syllogism. I am particularly interested in how theological questions contributed to the introduction of some influential new medieval ideas, such as the extensional sameness of the subject as the basis of predication, the interpretation of the expository syllogism from this point of view, and the explication of the logical subject of universal and particular syllogistic premises with the phrase `Anything/something which is A. . .'. I end with some remarks about the increasing medieval awareness that these developments were beyond Aristotle's purview

The editors comment that the core of this book is formed by the papers presented as a special session at the Ninth International Congress of Medieval Philosophy, honoring Norman Kretzmann’s contribution to the study of medieval philosophy. They decided to publish these papers with other essays devoted to issues in Aquinas’s moral theory specially commissioned from a group of Kretzmann’s colleagues, friends, and former students. The book, consisting of ten essays and a list of Kretzmann’s publications on Aquinas, is dedicated to Kretzmann, who died just months before the volume appeared.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.4 (2001) 587-589 [Access article in PDF] Maarten J. F. M. Hoenen and Paul J. J. M. Bakker, editors. Philosophie und Theologie des ausgehenden Mittelalters: Marsilius von Inghen und das Denken seiner Zeit. Leiden: Brill, 2000. Pp. x + 322. Cloth, $98.00. Albert of Saxony, Nicholas Oresme, and Marsilius of Inghen were among the fourteenth-century Parisian masters of arts who were influenced by Buridan's philosophy and, while continuing as master of arts, simultaneously pursued a degree in theology. Marsilius, born around 1340, was a very popular master in Paris from 1362. In 1366 he began the study of theology. He did not finish his theological studies in Paris, but later at the new university of Heidelberg (1393-4), where he held a chair of theology until his death in 1396.Marsilius wrote a number of treatises on logic, commentaries on Aristotle's works, commentaries on the Bible, a commentary on the Sentences and some tracts on ecclesiastical politics. His works were widely read and he was regarded as a representative of the via moderna and nominalist philosophy in the fifteenth century. Several scholars are currently studying and editing Marsilius's works. The collection of essays Philosophy and Theology in late Middle Ages, edited by Hoenen and Bakker, is a report on this ongoing work. It has been preceded by two similar research reports, Marsilius of Inghen, edited by H. Braakhuis and M. Hoenen (1992), and Marsilius von Inghen, Werk und Wirkung, edited by S. Wielgus (1993). Most of the articles in the present volume deal with special historical and doxographical questions. In this sense the title of the book is somewhat misleading, though the contributions themselves are of high scholarly quality and contain lots of interesting historical details and new research results.The first part involves four papers on late medieval conceptions of the relationship between philosophy and theology. Hoenen describes the increasing separation of theology from logic and philosophy as the context of Marsilius's theological work, using as examples his treatment of the doctrines of divine foreknowledge and creation from nothing. Sigrid Müller argues that those fourteenth-century theologians who were called representatives of nominalistic theology in the fifteenth century, such as William [End Page 587] of Ockham, Gregory of Rimini, and Marsilius Inghen, had a similar view of the relationship between language and reality, though their theological sources and solutions to particular questions varied. Manfred Schulze sheds light on Marsilius's theology by comparing his views on predestination, grace, and the freedom of the will with those of Gregory of Rimini and Gabriel Biel. These papers are preceded by William Courtenay's historically illuminating study of the teachers of theology in Paris during 1362-77.The papers on the relationship between philosophy and theology are learned and useful but somewhat general. What does it mean that philosophy and theology were increasingly separated by authors who after all were keen to make logical and semantic distinctions? Further light might have been shed on this question by concentrating more on the widely discussed controversies about logic and the Trinity which have recently been considered by many scholars. One position was to criticize the special logic of faith and to show that the alleged logical problems in theological doctrines are mainly based on incorrect interpretations of revealed truths. Showing this demanded discussions of logic and semantics in theology, as can also be seen in question nine of the first book of Marsilius of Inghen's Questions on the Sentences.The second part involves papers on specific themes in the works of Marsilius and attempts to identify some anonymous works. Henk Braakhuis deals with Marsilius's view on the question of the different senses of a proposition, which was mentioned in the famous prohibition statute of the Faculty of Arts in Paris in 1340 and was found interesting in many contexts, one of them being Aristotle's theory of sophistic refutations. Braakhuis's paper, which is a valuable contribution to the history of logic, contains...
