“More than any other living scholar of medieval philosophy, Gyula Klima has influenced the way we read and understand philosophical texts by showing how the questions they ask can be placed in a modern context without loss or distortion. The key to his approach is a respect for medieval authors coupled with a commitment to regarding their texts as a genuine source of insight on questions in metaphysics, theology, psychology, logic, and the philosophy of language—as opposed to assimilating what they say to modern doctrines, or using medieval discussions as a foil for ‘new and improved’ conceptual schemes.” Jack Zupko, University of Alberta “Gyula Klima is widely recognized as one of the world’s leading experts on thirteenth and fourteenth-century Latin philosophy, with his own, distinctive analytic approach, which brings out both the similarities and differences between medieval and contemporary logic and semantics.” John Marenbon, Trinity College, University of Cambridge “Gyula Klima has been a towering figure in the field of medieval philosophy for decades. His influence comprises not only the scholarly results of his work, but also intense and generous mentorship of students and junior colleagues. This volume is a perfect reflection of the esteem that he enjoys around the world, collecting excellent pieces by established as well as up-and-coming scholars of medieval philosophy.” Catarina Dutilh Novaes, Vrije Universiteit Amsterdam “For four decades now, Gyula Klima has been setting the standard among medievalists for philosophical sophistication and historical rigor. This collection of wide-ranging studies from leading scholars in the field offers a worthy tribute to that legacy.” Robert Pasnau, University of Colorado Boulder Gyula Klima is Professor of Philosophy at Fordham University, and Senior Research Fellow, Consultant, and the Director of Institute for the History of Ideas of the Hungarian Research Institute in Budapest. In 2022, the President of Hungary awarded him the Knight’s Cross of the Hungarian Order of Merit, “in recognition of his outstanding academic career, significant research work and exemplary leadership.” In this volume, colleagues, collaborators, and students celebrate Klima’s project with new essays on Plotinus, Anselm, Aquinas, Buridan, Ockham and others, exploring specific questions in philosophy of mind, philosophy of language, metaphysics, and logic. No contemporary surpasses Kripke and Klima in semantics and metaphysics, but only Gyula Klima’s thought ranges flawlessly over classical philosophy as well. The volume is a fitting tribute to the master. David Twetten, Marquette University

Medieval semantic theories develop out of Aristotle’s On Interpretation, in which he notes that “Spoken sounds are symbols of affections in the soul, and written marks symbols of spoken sounds” (tr. J. L. Ackrill, OUP 1984). The medieval commentary tradition elaborates on Aristotle’s theory in light of various epistemological and metaphysical commitments, including those entailed by the doctrine of the transcendentals that emerges from the tradition in the writings of Philip the Chancellor (d. 1236). Transcendental attributes such as unity, truth and goodness (properties that figure into most if not all accounts of the transcendentals) characterize every being as such, and hence the doctrine of the transcendentals promised some knowledge of God. This hope, together with the general medieval consensus that the cognitive acts by which we grasp extra-mental entities are veridical (i.e., in most cases, these acts represent what the cognizing subject takes them to represent) encouraged medieval thinkers to devote considerable effort to discerning how concepts latch onto reality. Medieval Metaphysics, or Is It “Just Semantics”? follows these attempts as concerns the signification of theological discourse in general and Trinitarian semantics in particular, the proper object of the intellect, and what is signified through quidditative or essential definition.

Contemporary introductions to the theme of self-knowledge too often trace its emergence in the history of philosophy to thinkers such as René Descartes and David Hume. Whereas Descartes conceives of self-knowledge as intimate and first-personal, Hume contends that it is limited to our awareness of our impressions and ideas. In point of fact, self-knowledge is a perennial theme. We may, for instance, trace the lineage of Hume and Descartes on these matters to Aristotle and Plato, respectively. This volume studies philosophical treatments of self-knowledge in the Medieval Latin West. It comprises two sets of papers; the first is taken from an author-meets-critics session on Therese Scarpelli-Cory’s Aquinas on Human Self Knowledge, which advances the thesis that Aquinas’s theory of self-knowledge wherein the intellect grasps itself in its activity bridges the divide between mediated and first-personal self-knowledge. The second set of papers discuss self-knowledge in terms of self-fulfilment. Authors look to Aquinas’s account of how we can know when we have acquired the virtues necessary for human happiness, as well as the medieval traditions of mysticism and theology, which offer accounts of transformative self-knowledge, the fulfilment that this brings to our emotional and physical selves, and the authority to teach and counsel about what this awareness confers.

For medieval thinkers, the distinction between intentional and extra-mental reality does not precipitate a Kantian turn to the subject. Rather, they allow that metaphysics and natural philosophy study things as they are and leave to logic the investigation of things as conceived. Within this broad scheme, there is much room for debate regarding whether and to what extent Aristotle’s categories comprise an accurate picture of what types of things exist. Closely tied to consideration of what types of things exist are questions concerning how language reflects the relations that hold among these things. For instance, both substances and the accidents parasitic on their existence are said to be, but not in the same way. The essays in Categories, and What is Beyond draw on the philosophical traditions of late antiquity and the middle ages to study what types of things there are, the extent to which our knowledge of these entities is accurate, how (and whether) the semantics of analogy are competent to adjust for the difference and diversity found amongst analogates, and some ways in which these considerations bear on our ability to learn and speak of God.

Knowledge, Mental Language, and Free Will traverses the medieval philosophical landscape of metaphysics, logic and natural philosophy. Alexander W. Hall discusses Thomas Aquinas’s interpretation of Aristotle’s doctrine of per se predication as it occurs in the conclusion of scientific demonstrations, i.e., of arguments producing scientific knowledge in the strict sense. Henrik Lagerlund and Catarina Dutilh Novaes take up medieval studies of mental language in the writings of Peter of Ailly and William Ockham. Works in this genre seek to discern what concepts are concepts of, the ontological status of concepts as entities, and how concepts stand for and represent things in the world. Lastly, Walter Redmond comments on and translates the prologue to and first chapter of the Mexican Jesuit Father Matías Blanco’s (d. 1734) The Three-Stranded Cord [Funiculus triplex], where Blanco treats the antinomy between freedom and determination, modal semantics, tense logic and the logical status of counterfactuals in an attempt to reconcile human freedom with God’s causality and omniscience.

Originally published in 1993, Modalities in Medieval Philosophy looks at the idea of modality as multiplicity of reference with respect to alternative domains. The book examines how this emerged in early medieval discussions and addresses how it was originally influenced by the theological conception of God acting by choice. After a discussion of ancient modal paradigms, the author traces the interplay of old and new modal views in medieval logic and semantics, philosophy and theology. A detailed account is given of late medieval discussions of the new modal logic, epistemic logic, and the logic norms. These theories show striking similarities to some basic tenets of contemporary approaches to modal matters. This work will be of considerable interest to historians of philosophy and ideas and philosophers of logic and metaphysics.

This volume is about the most mind-boggling sacrament of the Christian faith, also referred to as the Sacrament of the Altar, the Eucharist: in its Roman Catholic interpretation, the conversion of the substance of the bread and wine into the body and blood of Christ for Holy Communion. The challenge of providing a rational interpretation of this doctrine of faith proved to be one of the most contentious issues in the Western history of ideas, apparently going against self-evident metaphysical principles (requiring accidents existing without a substance, and a body in several places at the same time, etc.), and dividing schools of thought, indeed, eventually, warring religious factions. The volume addresses both the metaphysical, theoretical issues involved in this challenge and the historical, theological developments of how meeting this challenge played out first in the schools and even later in religious schisms, leading to the paradigmatic shift from medieval to modern forms of thought. The essays of the volume derive from the lectures of an eponymous international conference held in Budapest, Hungary, which was also the occasion of founding the Society for the History of European Ideas (SEHI); accordingly, the book is the first volume of the annual Proceedings of the SEHI. This book is aimed just as much at laymen and religious scholars seeking a better understanding of their faith as at anyone seeking this understanding with a non-religious attitude.
