Theories Of Vision From Al Kindi To Kepler

Kepler's successful solution to the problem of vision early in the seventeenth century was a theoretical triumph as significant as many of the more celebrated developments of the scientific revolution. Yet the full import of Kepler's arguments can be grasped only when they are viewed against the background of ancient, medieval, and Renaissance visual theory. David C. Lindberg provides this background, and in doing so he fills the gap in historical scholarship and constructs a model for tracing the development of scientific ideas. David C. Lindberg is professor and chairman of the department of the history of science at the University of Wisconsin, Madison.

In order to understand "vision", we have to look into concepts of blindness, both diegetically in typical film characters and in the representation of sight or lack thereof. A critical-historical investigation into theories of vision shows that the way we understand visuality today – scientifically and culturally – is very different from pre-modern notions and practices. In this book, Dago Schelin questions categories such as active and passive vision, tactile visuality, as well as blind vision, and discusses them alongside a variety of movies that deal with vision and blindness. Is there a connection between the filmmaker's gaze and an older pre-Keplerian ontology of vision? What is the role of sound in vision? Are our eyes mere camcorders or might they be projectors? These and other questions comprise the fascinating journey on which this study embarks.

"Bold, deeply learned, and important, offering a provocative thesis that is worked out through legal and archival materials and in subtle and original readings of literary texts. Absolutely new in content and significantly innovative in methodology and argument, Stumbling Blocks Before the Blind offers a cultural geography of medieval blindness that invites us to be more discriminating about how we think of geographies of disability today." ---Christopher Baswell, Columbia University "A challenging, interesting, and timely book that is also very well written . . . Wheatley has researched and brought together a leitmotiv that I never would have guessed was so pervasive, so intriguing, so worthy of a book." ---Jody Enders, University of California, Santa Barbara Stumbling Blocks Before the Blind presents the first comprehensive exploration of a disability in the Middle Ages, drawing on the literature, history, art history, and religious discourse of England and France. It relates current theories of disability to the cultural and institutional constructions of blindness in the eleventh through fifteenth centuries, examining the surprising differences in the treatment of blind people and the responses to blindness in these two countries. The book shows that pernicious attitudes about blindness were partially offset by innovations and ameliorations---social; literary; and, to an extent, medical---that began to foster a fuller understanding and acceptance of blindness. A number of practices and institutions in France, both positive and negative---blinding as punishment, the foundation of hospices for the blind, and some medical treatment---resulted in not only attitudes that commodified human sight but also inhumane satire against the blind in French literature, both secular and religious. Anglo-Saxon and later medieval England differed markedly in all three of these areas, and the less prominent position of blind people in society resulted in noticeably fewer cruel representations in literature. This book will interest students of literature, history, art history, and religion because it will provide clear contexts for considering any medieval artifact relating to blindness---a literary text, a historical document, a theological treatise, or a work of art. For some readers, the book will serve as an introduction to the field of disability studies, an area of increasing interest both within and outside of the academy.

Al-Kindi was the first philosopher of the Islamic world. He lived in Iraq and studied in Baghdad, where he became attached to the caliphal court. In due course he would become an important figure at court: a tutor to the caliph's son, and a central figure in the translation movement of the ninth century, which rendered much of Greek philosophy, science, and medicine into Arabic. Al-Kindi's wide-ranging intellectual interests included not only philosophy but also music, astronomy, mathematics, and medicine. Through deep engagement with Greek tradition al-Kindi developed original theories on key issues in the philosophy of religion, metaphysics, physical science, and ethics. He is especially known for his arguments against the world's eternity, and his innovative use of Greek ideas to explore the idea of God's unity and transcendence. Despite al-Kindi's historical and philosophical importance no book has presented a complete, in-depth look at his thought until now. In this accessible introduction to al-Kindi's works, Peter Adamson surveys what is known of his life and examines his method and his attitude towards the Greek tradition, as well as his subtle relationship with the Muslim intellectual culture of his day. Above all the book focuses on explaining and evaluating the ideas found in al-Kindi's wide-ranging philosophical corpus, including works devoted to science and mathematics. Throughout, Adamson writes in language that is both serious and engaging, academic and approachable. This book will be of interest to experts in the field, but it requires no knowledge of Greek or Arabic, and is also aimed at non-experts who are simply interested in one of the greatest of Islamic philosophers.

In this volume of conference papers originally presented at the University of Oklahoma, a distinguished group of scholars examines episodes in the transmission of premodern science and provides new insights into its cultural, philosophical and historical significance.

Drawing on optic theory, ethnography, and the visual cultures of Christianity, this volume explores various discourses of vision in early modern Europe and the colonial Americas.
