The cosmology of Johannes Kepler remains a mystery. On the one hand, Kepler’s speculations on spiritual faculties are seen as the remnants of Renaissance philosophy. On the other, his comparison of the cosmos to a clock summons the mechanical metaphor that shaped modern science. This book explores the inseparable connections between Kepler’s vitalistic views and his more enduring accomplishments in astronomy. The key argument is that Kepler’s ‘celestial biology’ served as a bridge between his revolutionary astronomy and other ‘less scientific’ interests, particularly astrology. Kepler's Cosmological Synthesis sheds new light on one of the foundational figures of the Scientific Revolution. By uncovering a new form of coherence in Kepler’s world picture, it traces the unlikely intersections of mechanism and vitalism that transformed the fabric of the heavens.

A committed Lutheran excommunicated from his own church, a friend to Catholics and Calvinists alike, a layman who called himself a “priest of God,” a Copernican in a world where Ptolemy still reigned, a man who argued at the same time for the superiority of one truth and the need for many truths to coexist—German astronomer Johannes Kepler was, to say the least, a complicated figure. With The Pursuit of Harmony, Aviva Rothman offers a new view of him and his achievements, one that presents them as a story of Kepler’s attempts to bring different, even opposing ideas and circumstances into harmony. Harmony, Rothman shows, was both the intellectual bedrock for and the primary goal of Kepler’s disparate endeavors. But it was also an elusive goal amid the deteriorating conditions of his world, as the political order crumbled and religious war raged. In the face of that devastation, Kepler’s hopes for his theories changed: whereas he had originally looked for a unifying approach to truth, he began instead to emphasize harmony as the peaceful coexistence of different views, one that could be fueled by the fundamentally nonpartisan discipline of mathematics.

New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it about In the late fifteenth century, it was believed that the earth stood motionless at the centre of a small, ordered cosmos. Just over two centuries later, everything had changed. Not only was the sun the centre of creation, but the entire practice of science had been revolutionised. This is the story of that astonishing transformation, told through the words of the astronomers and mathematicians at its heart. Bringing together excerpts from the works and letters of Copernicus, Galileo, Kepler, Descartes, Newton and others for the first time, The Dawn of Modern Cosmology is the definitive record of one of the great turning points in human history. Edited with Translations, Notes and an Introduction by Aviva Rothman

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.

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 volume addresses the history and epistemology of early modern cosmology. The authors reconstruct the development of cosmological ideas in the age of ‘scientific revolution’ from Copernicus to Leibniz, taking into account the growth of a unified celestial-and-terrestrial mechanics. The volume investigates how, in the rise of the new science, cosmology displayed deep and multifaceted interrelations between scientific notions (stemming from mechanics, mathematics, geometry, astronomy) and philosophical concepts. These were employed to frame a general picture of the universe, as well as to criticize and interpret scientific notions and observational data. This interdisciplinary work reconstructs a conceptual web pervaded by various intellectual attitudes and drives. It presents an historical–epistemological unified itinerary which includes Copernicus, Kepler, Galileo, Descartes, Huygens, Newton and Leibniz. For each of the scientists and philosophers, a presentation and commentary is made of their cosmological views, and where relevant, outlines of their most relevant physical concepts are given. Furthermore, the authors highlight the philosophical and epistemological implications of their scientific works. This work is helpful both as a synthetic overview of early modern cosmology, and an analytical exposition of the elements that were intertwined in early-modern cosmology. This book addresses historians, philosophers, and scientists and can also be used as a research source book by post-graduate students in epistemology, history of science and history of philosophy.

This book describes how and why the early modern period witnessed the marginalisation of astrology in Western natural philosophy, and the re-adoption of the cosmological view of the existence of a plurality of worlds in the universe, allowing the possibility of extraterrestrial life. Founded in the mid-1990s, the discipline of astrobiology combines the search for extraterrestrial life with the study of terrestrial biology – especially its origins, its evolution and its presence in extreme environments. This book offers a history of astrobiology's attempts to understand the nature of life in a larger cosmological context. Specifically, it describes the shift of early modern cosmology from a paradigm of celestial influence to one of celestial inhabitation. Although these trends are regarded as consequences of Copernican cosmology, and hallmarks of a modern world view, they are usually addressed separately in the historical literature. Unlike others, this book takes a broad approach that examines the relationship of the two. From Influence to Inhabitation will benefit both historians of astrology and historians of the extraterrestrial life debate, an audience which includes researchers and advanced students studying the history and philosophy of astrobiology. It will also appeal to historians of natural philosophy, science, astronomy and theology in the early modern period.

This Encyclopedia offers a fresh, integrated and creative perspective on the formation and foundations of philosophy and science in European modernity. Combining careful contextual reconstruction with arguments from traditional philosophy, the book examines methodological dimensions, breaks down traditional oppositions such as rationalism vs. empiricism, calls attention to gender issues, to ‘insiders and outsiders’, minor figures in philosophy, and underground movements, among many other topics. In addition, and in line with important recent transformations in the fields of history of science and early modern philosophy, the volume recognizes the specificity and significance of early modern science and discusses important developments including issues of historiography (such as historical epistemology), the interplay between the material culture and modes of knowledge, expert knowledge and craft knowledge. This book stands at the crossroads of different disciplines and combines their approaches – particularly the history of science, the history of philosophy, contemporary philosophy of science, and intellectual and cultural history. It brings together over 100 philosophers, historians of science, historians of mathematics, and medicine offering a comprehensive view of early modern philosophy and the sciences. It combines and discusses recent results from two very active fields: early modern philosophy and the history of (early modern) science.

Spanning the course of his career, this book brings new light to Kepler's vitalistic views and their central place in his world picture. It challenges our view of Kepler as a nascent mechanical philosopher who fell back on an older form of physics.

In Measuring Shadows, Raz Chen-Morris demonstrates that a close study of Kepler’s Optics is essential to understanding his astronomical work and his scientific epistemology. He explores Kepler’s radical break from scientific and epistemological traditions and shows how the seventeenth-century astronomer posited new ways to view scientific truth and knowledge. Chen-Morris reveals how Kepler’s ideas about the formation of images on the retina and the geometrics of the camera obscura, as well as his astronomical observations, advanced the argument that physical reality could only be described through artificially produced shadows, reflections, and refractions. Breaking from medieval and Renaissance traditions that insisted upon direct sensory perception, Kepler advocated for instruments as mediators between the eye and physical reality, and for mathematical language to describe motion. It was only through this kind of knowledge, he argued, that observation could produce certainty about the heavens. Not only was this conception of visibility crucial to advancing the early modern understanding of vision and the retina, but it affected how people during that period approached and understood the world around them.
