In this critical edition of Nicole Oresme's 14th-century treatise on atmospheric refraction, Oresme uses optics and infinitesimals to help solve this vexing problem of astronomy, proposing that light travels along a curve through the atmosphere, centuries before Hooke and Newton.
This book offers an entirely new perspective on the alleged incompatibility between Aristotelian philosophy and the mathematical methods and principles that form the basis of modern science. It surveys the tradition of the Oxford Calculators from its beginnings in the fourteenth century until Leibniz and the philosophy of the seventeenth century and explores how their various techniques of quantification expanded the conceptual and methodological limits of Aristotelianism.
Fearful Spirits, Reasoned Follies by Michael D. Bailey Pdf
Superstitions are commonplace in the modern world. Mostly, however, they evoke innocuous images of people reading their horoscopes or avoiding black cats. Certain religious practices might also come to mind-praying to St. Christopher or lighting candles for the dead. Benign as they might seem today, such practices were not always perceived that way. In medieval Europe superstitions were considered serious offenses, violations of essential precepts of Christian doctrine or immutable natural laws. But how and why did this come to be? In Fearful Spirits, Reasoned Follies, Michael D. Bailey explores the thorny concept of superstition as it was understood and debated in the Middle Ages. Bailey begins by tracing Christian thinking about superstition from the patristic period through the early and high Middle Ages. He then turns to the later Middle Ages, a period that witnessed an outpouring of writings devoted to superstition-tracts and treatises with titles such as De superstitionibus and Contra vitia superstitionum. Most were written by theologians and other academics based in Europe's universities and courts, men who were increasingly anxious about the proliferation of suspect beliefs and practices, from elite ritual magic to common healing charms, from astrological divination to the observance of signs and omens. As Bailey shows, however, authorities were far more sophisticated in their reasoning than one might suspect, using accusations of superstition in a calculated way to control the boundaries of legitimate religion and acceptable science. This in turn would lay the conceptual groundwork for future discussions of religion, science, and magic in the early modern world. Indeed, by revealing the extent to which early modern thinkers took up old questions about the operation of natural properties and forces using the vocabulary of science rather than of belief, Bailey exposes the powerful but in many ways false dichotomy between the "superstitious" Middle Ages and "rational" European modernity.

From its inception in Greek antiquity, the science of optics was aimed primarily at explaining sight and accounting for why things look as they do. By the end of the seventeenth century, however, the analytic focus of optics had shifted to light: its fundamental properties and such physical behaviors as reflection, refraction, and diffraction. This dramatic shift—which A. Mark Smith characterizes as the “Keplerian turn”—lies at the heart of this fascinating and pioneering study. Breaking from previous scholarship that sees Johannes Kepler as the culmination of a long-evolving optical tradition that traced back to Greek antiquity via the Muslim Middle Ages, Smith presents Kepler instead as marking a rupture with this tradition, arguing that his theory of retinal imaging, which was published in 1604, was instrumental in prompting the turn from sight to light. Kepler’s new theory of sight, Smith reveals, thus takes on true historical significance: by treating the eye as a mere light-focusing device rather than an image-producing instrument—as traditionally understood—Kepler’s account of retinal imaging helped spur the shift in analytic focus that eventually led to modern optics. A sweeping survey, From Sight to Light is poised to become the standard reference for historians of optics as well as those interested more broadly in the history of science, the history of art, and cultural and intellectual history.
A History of Natural Philosophy by Edward Grant Pdf
Natural philosophy encompassed all natural phenomena of the physical world. It sought to discover the physical causes of all natural effects and was little concerned with mathematics. By contrast, the exact mathematical sciences were narrowly confined to various computations that did not involve physical causes, functioning totally independently of natural philosophy. Although this began slowly to change in the late Middle Ages, a much more thoroughgoing union of natural philosophy and mathematics occurred in the seventeenth century and thereby made the Scientific Revolution possible. The title of Isaac Newton's great work, The Mathematical Principles of Natural Philosophy, perfectly reflects the new relationship. Natural philosophy became the 'Great Mother of the Sciences', which by the nineteenth century had nourished the manifold chemical, physical, and biological sciences to maturity, thus enabling them to leave the 'Great Mother' and emerge as the multiplicity of independent sciences we know today.
These articles discuss the appropriation of Greek science by scholars in the world of medieval Islam. After presenting the historiography of this process, the volume focuses on Ibn al-Haytham, one of the most influential figures of the 11th century, and on his contribution to the science of optics and the psychology of vision. The work then analyzes how Greek thought was developed in the Islamic world, based on studies of Euclid's geomotry and critiques of Ptolemaic astronomy. Finally, some articles consider the history of logic - Aristotelian syllogism and Avicenna's views on the subject matter of logic.
