MEDIEVAL PHILOSOPHY ‘Dr Marenbon’s book is an authoritative, comprehensive, yet accessible survey of medieval philosophy, written by an expert at the height of his critical powers. Not only does the book guide the reader through the diverse issues of medieval philosophy, but provides sagacious instruction and illuminating commentary on the central topics of its chosen period of study.’ Martin Stone, Katholieke Universiteit Leuven, Belgium. ‘Marenbon has managed to write about an enormous array of topics in a lucid and accessible way. His prose is clear without being condescending, informative without being either patronizing or importunate. The beginner will find it approachable and unpretentious.’ Peter King, University of Toronto, Canada This new introduction replaces Marenbon’s best-selling editions Early Medieval Philosophy (1983) and Later Medieval Philosophy (1987) to present a single author- itative and comprehensive study of the period. An entirely new book, written in the light of the scholarship of the last twenty years, it will be the standard companion for all students of medieval philosophy. It gives a lucid and engaging account of the history of philosophy in the Middle Ages, discussing the main writers and ideas, the social and intellectual contexts, and the important concepts used in medieval philosophy. Medieval Philosophy gives a chronological account which: • treats all four main traditions of philosophy that stem from the Greek heritage of late antiquity: Greek Christian philosophy, Latin philosophy, Arabic philos- ophy and Jewish philosophy • provides a series of ‘study’ sections for close attention to arguments and shorter ‘interludes’ that point to the wider questions of the intellectual context • combines philosophical analysis with historical background • includes a helpful detailed guide to further reading and an extensive bibliography All students of medieval philosophy, medieval history, theology or religion will find this necessary reading. John Marenbon is a senior research fellow at Trinity College, Cambridge, UK.

But it owes its origin to a request for one. Would I, asked my publishers, like to up-date my two books so that they could be issued as a single volume? I quickly realized that there was so much I wanted to change, or rather, so little I was willing to retain, that it would be much better to offer an entirely new Introduction. Routledge bravely accepted my proposal, and here now is the book. In its conception of what constitutes medieval philosophy, it could hardly be more different from the two earlier Introductions. They focussed exclusively on the Latin tradition, with Islamic and Jewish material introduced only in so far as it affected the Christian thinkers in the universities. This new book aims to introduce all four main traditions of medieval philosophy that go back to the same roots in late antiquity: the Greek Christian tradition, the Latin tradition, the Arabic tradition and the Jewish tradition (written in Arabic and in Hebrew). Chronologically, the scope may seem at first to be not so different from that of my old books, since the stopping date is 1400, only about seventy-five years later than the improbably early point where Later Medieval Philosophy finished. But, as I argue in my Introduction and in the final, brief chapter, 1400 is a completely arbitrary deadline, and the best approach to the material considered here might be to envisage a period running from c. 200 to c. 1700 – a long Middle Ages so long that it hardly remains the Middle Ages – as a unit for teaching and study. Although, then, this book covers almost all the ground that would be expected of an introduction to medieval philosophy, to me its central point lies more in what it fails, in its present state, to do.
