“Throughout this book, but especially in its conclusion, Marenbon steps back and reflects upon methodologies of historians of philosophy. [Marenbon] has identified some weighty issues that any historian of philosophy must address, and one would be well advised to read Marenbon’s thoughtful remarks on this subject.” —Vivarium "Abelard in Four Dimensions is an excellent introduction to the study of Peter Abelard. The 'four dimensions' in the title refer to future, past, and present—Abelard's and our own. . . . In his conclusion, Marenbon reflects intelligently on how best to bring medieval thinkers into the contemporary discussion: not by distortion, forcing medieval ideas into 'a conceptual framework where they do not belong,' but by asking ourselves not only how they resemble modern positions, but also how the problems addressed differ from those today's philosophers pose." —The Medieval Review “Much of what is explored here is explored with clarity, care, and judgment. In an important sense Marenbon proves the thesis of the book: that historical understanding and background helpfully informs attempts to see in thinkers from another era versions of contemporary theories and can prevent misreadings of many kinds.” —Journal of the History of Philosophy “In this book, John Marenbon takes on select issues from Abelard’s philosophy and theology that have proven to be problematic. These he submits to close examination, hewing his own path in submitting these topics to careful scrutiny, never coming to easy conclusions, but offering original insights. For audiences responsive to Marenbon’s approach his book offers value.” —Mediaevistik "As a volume of Conway lectures, it is a worthy peer to sit alongside the recent contributions of Rosamund McKitterick, Jonathan Riley Smith, A. C. Spearing, and Barbara Newman. I hope this book will reach a wider audience of medievalists than only philosophers, theologians, and twelfth-century specialists (for whom it will be indispensable), if only for the tentative but convincing answer Marenbon provides to the immediately pressing question of the relevance of medieval studies." —Speculum "Marenbon (Cambridge University), an important scholar of medieval philosophy, here returns to a topic that occupied him some years ago: the philosophy of Peter Abelard. Rather than serving as a general treatment of Abelard's philosophy, this book focuses on four different ways of reading the philosopher: in terms of his predecessors, his contemporaries, and his historical influence, and in terms of contemporary philosophy. This volume . . . will not disappoint. It should prove useful to students of Peter Abelard and of medieval thought more generally." —Choice "This searching, thorough, and original study examines Abelard's past, present, and future, and our present. John Marenbon offers the best enquiry yet made into the sequence of Abelard's writings and their chronology, followed by an incisive and highly illuminating account of the various, successive formulations of his 'unpopular argument' to the effect that God cannot do otherwise than as he does. This is an accomplished work which will be eagerly read and hugely appreciated by students and their teachers on courses of philosophy, theology, and history." —David Luscombe, University of Sheffield
