Mathematical Theologies uncovers the lost history of Christianity's encounters with Pythagorean religious ideas before the Renaissance. David Albertson shows that the writings of Thierry of Chartres (d. 1157) and Nicholas of Cusa (d. 1464) represent a robust Christian Neopythagoreanism that reconceived the Trinity and the Incarnation within the framework of Greek number theory. Their sophisticated mathematical theologies challenge contemporary assumptions about the relation of religion and modern science. David Albertson surveys the slow formation of Neopythagorean theologies of the divine One from the Old Academy through Middle Platonism into the Middle Ages. Against this backdrop, Thierry of Chartres's writings stand out as the first authentic retrieval and incorporation of Neopythagoreanism within western Christianity. By reading Boethius and Augustine against the grain, Thierry reactivated a suppressed potential in ancient Christian traditions that harmonized the divine Word with notions of divine Number. Despite fame during his lifetime, Thierry's ideas remained well outside the medieval mainstream.Nicholas rediscovered anonymous fragments of Thierry and his medieval readers, and drew on them liberally in his first mystical treatise. Yet tensions among this collection of sources drove Cusanus to try to reconcile their competing understandings of Word and Number. Over three decades Nicholas eventually learned how to articulate traditional Christian dogmas within a Neopythagorean cosmology of mathematized nature - anticipating the situation of modern Christian thought after the seventeenth century. Mathematical Theologies skillfully guides readers through the newest scholarship on Pythagoreanism, the school of Chartres, and Cusanus, while revising some of the categories that have separated those fields in the past.

Does "nature" still exist? Common wisdom now acknowledges the malleability of nature, the complex reality that circumscribes and constitutes the human. Weather patterns, topographical contours, animal populations, and even our own genetic composition-all of which previously marked the boundary of human agency-now appear subject to our intervention. Some thinkers have suggested that nature has disappeared entirely and that we have entered a postnatural era; others note that nature is an ineradicable context for life. Christian theology, in particular, finds itself in an awkward position. Its Western traditions have long relied upon a static "nature" to express the dynamism of "grace," making nature a foundational category within theology itself. This means that any theological inquiry into the changing face of nature must be reflexive and radically interdisciplinary. This book brings leading natural and social scientists into conversation with prominent Christian theologians and ethicists to wrestle collectively with difficult questions. Is nature undergoing fundamental change? What role does nature play in theological ethics? How might ethical deliberation proceed "without nature" in the future? What does the religious drive to transform human nature have to do with the technological quest to transcend human limits? Would the end of nature make grace less comprehensible?
