Unifying Heaven And Earth Essays In The History Of Early Modern Cosmology

One of the most significant events in the history of Western civilization was the cosmological revolution of the 16th and 17th centuries. Among the most salient factors in this change, described by Alexandre Koyré as the ‘destruction of the cosmos’ inherited from ancient Greece, were Copernican heliocentrism and the substitution of a homogeneous universe for the hierarchical cosmos of the Platonic and Aristotelian tradition. Starting with a new approach to the issue of the presence of Islamic astronomical devices in Copernicus’ work and a thorough reappraisal of the cosmological views of Paracelsus, the book deals mainly with the abolition of cosmological dualism and the ways in which it affected the decline of astrology over the 17th century. Other related topics include planetary order and theories of world harmony, the cause of planetary motion in the Tychonic world system or the discussion on comets in Germany through the first presentation of a manuscript treatise by Michael Maestlin on the great comet of 1618.

This open access book explores commentaries on an influential text of pre-Copernican astronomy in Europe. It features essays that take a close look at key intellectuals and how they engaged with the main ideas of this qualitative introduction to geocentric cosmology. Johannes de Sacrobosco compiled his Tractatus de sphaera during the thirteenth century in the frame of his teaching activities at the then recently founded University of Paris. It soon became a mandatory text all over Europe. As a result, a tradition of commentaries to the text was soon established and flourished until the second half of the 17th century. Here, readers will find an informative overview of these commentaries complete with a rich context. The essays explore the educational and social backgrounds of the writers. They also detail how their careers developed after the publication of their commentaries, the institutions and patrons they were affiliated with, what their agenda was, and whether and how they actually accomplished it. The editor of this collection considers these scientific commentaries as genuine scientific works. The contributors investigate them here not only in reference to the work on which it comments but also, and especially, as independent scientific contributions that are socially, institutionally, and intellectually contextualized around their authors.

This volume considers contingency as a historical category resulting from the combination of various intellectual elements – epistemological, philosophical, material, as well as theological and, broadly speaking, intellectual. With contributions ranging from fields as diverse as the histories of physics, astronomy, astrology, medicine, mechanics, physiology, and natural philosophy, it explores the transformation of the notion of contingency across the late-medieval, Renaissance, and the early modern period. Underpinned by a necessitated vision of nature, seventeenth century mechanism widely identified apparent natural irregularities with the epistemological limits of a certain explanatory framework. However, this picture was preceded by, and in fact emerged from, a widespread characterization of contingency as an ontological trait of nature, typical of late-Scholastic and Renaissance science. On these bases, this volume shows how epistemological categories, which are preconditions of knowledge as “historically-situated a priori” and, seemingly, self-evident, are ultimately rooted in time. Contingency is intrinsic to scientific practice. Whether observing the behaviour of a photon, diagnosing a patient, or calculating the orbit of a distant planet, scientists face the unavoidable challenge of dealing with data that differ from their models and expectations. However, epistemological categories are not fixed in time. Indeed, there is something fundamentally different in the way an Aristotelian natural philosopher defined a wonder or a “monstrous” birth as “contingent”, a modern scientist defines the unexpected result of an experiment, and a quantum physicist the behavior of a photon. Although to each inquirer these instances appeared self-evidently contingent, each also employs the concept differently.

By examining the pressing questions the supernova of 1604 prompted, Kepler’s New Star traces the enduring impact of Kepler and his star on the course of modern science.

What do scientists know about the possibility of life outside our solar system? How does Catholic science fiction imagine such worlds? What are the implications for Catholic thought? This collection brings together leading scientists, philosophers, theologians, and science fiction authors in the Catholic tradition to examine these issues. In the first section, Christian scientists detail the latest scientific findings regarding the possibility of life on exoplanets. The second part brings together leading Catholic science fiction authors who describe how “alien” life forms have been prevalent in the Catholic imagination from the Middle Ages right up to the present day. In the final section, Catholic philosophers and theologians examine the implications of discovering intelligent life elsewhere in the universe. Rather than worrying that the discovery of intelligent extraterrestrials might threaten the dignity of humans or their existence, the contributors here maintain that such creatures should be welcomed as fellow creatures of God and potential subjects of divine salvation.

The early modern era produced the Scientific Revolution, which originated our present understanding of the natural world. Concurrently, philosophers established the conceptual foundations of modernity. This rich and comprehensive volume surveys and illuminates the numerous and complicated interconnections between philosophical and scientific thought as both were radically transformed from the late sixteenth to the mid-eighteenth century. The chapters explore reciprocal influences between philosophy and physics, astronomy, mathematics, medicine, and other disciplines, and show how thinkers responded to an immense range of intellectual, material, and institutional influences. The volume offers a unique perspicuity, viewing the entire landscape of early modern philosophy and science, and also marks an epoch in contemporary scholarship, surveying recent contributions and suggesting future investigations for the next generation of scholars and students.

In 1984, Noel Swerdlow and Otto Neugebauer argued that Nicolaus Copernicus (1473–1543) explained planetary motion by using mathematical devices and astronomical models originally developed by Islamic astronomers in the thirteenth and fourteenth centuries. Was this a parallel development, or did Copernicus somehow learn of the work of his predecessors, and if so, how? And if Copernicus did use material from the Islamic world, how then should we understand the European context of his innovative cosmology? Although Copernicus’s work has been subject to a number of excellent studies, there has been little attention paid to the sources and diverse cultures that might have inspired him. Foregrounding the importance of interactions between Islamic and European astronomers and philosophers, Before Copernicus explores the multi-cultural, multi-religious, and multi-lingual context of learning on the eve of the Copernican revolution, determining the relationship between Copernicus and his predecessors. Essays by Christopher Celenza and Nancy Bisaha delve into the European cultural and intellectual contexts of the fifteenth century, revealing both the profound differences between “them” and “us,” and the nascent attitudes that would mark the turn to modernity. Michael Shank, F. Jamil Ragep, Sally Ragep, and Robert Morrison depict the vibrant and creative work of astronomers in the Christian, Islamic, and Jewish worlds. In other essays, Rivka Feldhay, Raz Chen-Morris, and Edith Sylla demonstrate the importance of shifting outlooks that were critical for the emergence of a new worldview. Highlighting the often-neglected intercultural exchange between Islam and early modern Europe, Before Copernicus reimagines the scientific revolution in a global context.

Magic, Witchcraft, and Ghosts in the Enlightenment argues for the centrality of magical practices and ideas throughout the long eighteenth century. Although the hunt for witches in Europe declined precipitously after 1650, and the intellectual justification for natural magic came under fire by 1700, belief in magic among the general population did not come to a sudden stop. The philosophes continued to take aim at magical practices, alongside religion, as examples of superstitions that an enlightened age needed to put behind them. In addition to a continuity of beliefs and practices, the eighteenth century also saw improvement and innovation in magical ideas, the understanding of ghosts, and attitudes toward witchcraft. The volume takes a broad geographical approach and includes essays focusing on Great Britain (England and Ireland), France, Germany, and Hungary. It also takes a wide approach to the subject and includes essays on astrology, alchemy, witchcraft, cunning folk, ghosts, treasure hunters, and purveyors of magic. With a broad chronological scope that ranges from the end of the seventeenth century to the early nineteenth century, this volume is useful for undergraduates, postgraduates, scholars, and those with a general interest in magic, witchcraft, and spirits in the Enlightenment.
