This volume collects essays which are thematically connected through the work of Kent Emery Jr., to whom the volume is dedicated. A main focus lies on the attempts to bridge the gap between mysticism and a systematic approach to medieval philosophical thought. The essays address a wide range of topics concerning (a) the nature of the human soul (in philosophical and theological discourse); (b) medieval theories of cognition (natural and supernatural), self-knowledge and knowledge of God; (c) the human soul’s contemplation of, and union with, God; (d) the tradition of “the modes of theology” in the Middle Ages; (e) the relation between philosophy and theology. Various articles are dedicated to major figures of the 13th and 14th century philosophy, others display new material based on critical editions. Contributors are Jan A. Aertsen, Stephen Brown, Bernardo Carlos Bazán, William J. Courtenay, Alfredo Santiago Culleton, Silvia Donati, Bernd Goehring, Guy Guldentops, Daniel Hobbins, Roberto Hofmeister Pich, Georgi Kapriev, Steven P. Marrone, Stephen M. Metzger, Timothy B. Noone, Mikolaj Olszewski, Alessandro Palazzo, Garrett R. Smith, Andreas Speer, Carlos Steel, Loris Sturlese, Chris Schabel, Christian Trottmann, and Gordon A. Wilson.

Mystical Theology and Platonism in the Time of Cusanus engages with the history of mystical theology and Neoplatonic philosophy through the lens of the 15th century philosopher and theologian, Nicholas of Cusa. The volume comprises nineteen essays that break down the barriers between medieval and Renaissance studies, reinterpreting Cusanus’ place in the history of thought by exploring the archive that informed his thinking, while also interrogating his works by exploring them from the standpoint of their later reception by modern philosophers and theologians. The volume also offers tribute to the career of Donald F. Duclow, a leading scholar in the field of Cusanus studies in particular and of the history of mystical theology and Neoplatonic philosophy more generally.

Gerard of Abbeville (d. 1272) was the foremost secular theologian at the University of Paris during the third quarter of the thirteenth century. Significantly, Gerard’s corpus includes the most comprehensive treatment of the nature and extent of human knowledge from the generation before Henry of Ghent. Stephen M. Metzger’s study presents Gerard’s complete theory of human knowledge, which is a hierarchy extending from the knowledge acquired in faith, through scientific thought and culminating in the full vision of God by the blessed in patria. It is the fullest exposition of the life, works and thought of Gerard yet written and is augmented by the presentation for the first time of editions of several disputed questions and other texts.

The thirteenth century was a dynamic period in intellectual history which witnessed the establishment of the first universities, most famously at Paris and Oxford. At these and other major European centres of learning, English-born Franciscans came to hold prominent roles both in the university faculties of the arts and theology and in the local studia across Europe that were primarily responsible for training Franciscans. This volume explores the contributions to scholarship of some of the leading English Franciscans or Franciscan associates from this period, including Roger Bacon, Adam Marsh, John Pecham, Thomas of Yorke, Roger Marston, Robert Grosseteste, Adam of Exeter, Richard Rufus of Cornwall, and Bartholomew of England. Through focussed studies of these figures’ signature ideas, contributions will provide a basis for drawing comparisons between the English Franciscan school and others that existed at the time, most famously at Paris.

Thinking Theologically contains new insights into the place of the divine ideas in the pedagogical design of Aquinas’s Summa Theologiae. It subsequently challenges the false dichotomy between philosophy and theology in the interpretation of Aquinas’s engagement with the doctrine.

The Philosophy and Science of Roger Bacon offers new insights and research perspectives on one of the most intriguing characters of the Middle Ages, Roger Bacon. At the intersections between science and philosophy, the volume analyses central aspects of Bacon’s reflections on how nature and society can be perfected. The volume dives into the intertwining of Bacon’s philosophical stances on nature, substantial change, and hylomorphism with his scientific discussion of music, alchemy, and medicine. The Philosophy and Science of Roger Bacon also investigates Bacon’s projects of education reform and his epistemological and theological ground maintaining that humans and God are bound by wisdom, and therefore science. Finally, the volume examines how Bacon’s doctrines are related to a wider historical context, particularly in consideration of Peter John Olivi, John Pecham, Peter of Ireland, and Robert Grosseteste. The Philosophy and Science of Roger Bacon is a crucial tool for scholars and students working in the history of philosophy and science and also for a broader audience interested in Roger Bacon and his long-lasting contribution to the history of ideas.

Articles 56–59 of Henry of Ghent’s Summa is devoted to the trinitarian properties. Henry was the most important Christian theological thinker in the last quarter of the 13th century and his works were influential not only in his lifetime, but also in the following century and into the Renaissance. Henry’s Quaestiones ordinariae (Summa), articles 56–59 deal with the trinitarian properties and relations, topics of Henry’s lectures at the university in Paris. In these articles, dated around 1286, Henry treats generation, a property unique to the Father, and being generated, a property unique to the Son. The university in Paris distributed articles 56–59 by means of two successive exemplars divided into peciae. Manuscripts copied from each have survived and the text of the critical edition has been established based upon the reconstructed texts of these two exemplars.
