Scholastic philosophers in the thirteenth and fourteenth centuries advanced original and sophisticated accounts of the nature of cognition and mental representation. This dissertation analyzes some of the debates of that period, beginning with Thomas Aquinas and going on to consider a number of his most penetrating critics: Henry of Ghent , Peter John Olivi , William Ockham , and William Crathorn . The study begins with some of the theoretical foundations of scholastic theories of cognition, such as the nature of cognition, the link between cognition and immateriality, and the sense in which mental representation rests on a similarity between our ideas and the external world. Debate over these issues led later scholastics to give increasing attention to epistemology and the threat of skepticism. Henry of Ghent's epistemological focus led him to formulate an interesting and original argument for the Augustinian theory of divine illumination. Other scholastics--in particular Olivi and Ockham--were similarly concerned that the standard Aristotelian theory of cognition, as formulated by Aquinas, would lead to skepticism. Their response was to reject a central feature of Aquinas's account: that our knowledge of the external world is mediated by internal impressions . Olivi and Ockham eliminate such intermediaries entirely. For them our knowledge of the external world is throughly direct, and they reject the distinction, which I argue is central to Aquinas's account, between acts of cognition and internal objects for those acts. I conclude that the work of Olivi and Ockham is significant primarily because it challenges the picture of mind that comes so naturally to us: that the mind is a repository of images and ideas that are the inner objects of our perceptions and thoughts. ;The dissertation's second volume contains translations of the central texts

The Cambridge History of Medieval Philosophy comprises over fifty specially commissioned essays by experts on the philosophy of this period. Starting in the late eighth century, with the renewal of learning some centuries after the fall of the Roman Empire, a sequence of chapters take the reader through developments in many and varied fields, including logic and language, natural philosophy, ethics, metaphysics, and theology. Close attention is paid to the context of medieval philosophy, with discussions of the rise of the universities and developments in the cultural and linguistic spheres. A striking feature is the continuous coverage of Islamic, Jewish, and Christian material. There are useful biographies of the philosophers, and a comprehensive bibliography. The volume illuminates a rich and remarkable period in the history of philosophy and will be the authoritative source on medieval philosophy for the next generation of scholars and students alike.

The third volume of The Cambridge Translations of Medieval Philosophical Texts will allow scholars and students access in English, to major texts that form the debate over mind and knowledge at the center of medieval philosophy. Beginning with thirteenth-century attempts to classify the soul's powers and to explain the mind's place within the soul, the volume proceeds systematically to consider the scope of human knowledge and the role of divine illumination, intentionality and mental representation, and attempts to identify the object of human knowledge in terms of concepts and propositions. The authors included are Henry of Ghent, Peter John Olivi, William Alnwick, Peter Aureol, William Ockham, William Crathorn, Robert Holcot, Adam Wodeham as well as two anonymous Parisian masters of arts. This volume will be an important resource for scholars and students of medieval philosophy, history, theology and literature
