Although recent works on Galileo’s trial have reached new heights of erudition, documentation, and sophistication, they often exhibit inflated complexities, neglect 400 years of historiography, or make little effort to learn from Galileo. This book strives to avoid such lacunae by judiciously comparing and contrasting the two Galileo affairs, that is, the original controversy over the earth’s motion ending with his condemnation by the Inquisition in 1633, and the subsequent controversy over the rightness of that condemnation continuing to our day. The book argues that the Copernican Revolution required that the hypothesis of the earth’s motion be not only constructively supported with new reasons and evidence, but also critically defended from numerous old and new objections. This defense in turn required not only the destructive refutation, but also the appreciative understanding of those objections in all their strength. A major Galilean accomplishment was to elaborate such a reasoned, critical, and fair-minded defense of Copernicanism. Galileo’s trial can be interpreted as a series of ecclesiastic attempts to stop him from so defending Copernicus. And an essential thread of the subsequent controversy has been the emergence of many arguments claiming that his condemnation was right, as well as defenses of Galileo from such criticisms. The book’s particular yet overarching thesis is that today the proper defense of Galileo can and should have the reasoned, critical, and fair-minded character which his own defense of Copernicus had.

In 1633, the Roman Inquisition condemned Galileo as a suspected heretic for defending Copernicus's hypothesis of the earth's motion and denying the scientific authority of Scripture. This book draws upon Maurice A. Finocchiaro's earlier works, especially The Galileo Affair: A Documentary History (1989), to provide a brief, new documentary history of Galileo's trial that is simultaneously the most user-friendly and inclusive available.

Galileo’s Dialogue Concerning the Two Chief World Systems, published in Florence in 1632, was the most proximate cause of his being brought to trial before the Inquisition. Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

In 1633 the Roman Inquisition condemned Galileo as a suspected heretic for defending the astronomical theory that the earth moves, and implicitly assuming the theological principle that Scripture is not scientific authority. This controversial event has sent ripples down the centuries, embodying the struggle between a thinker who came to be regarded as the Father of Modern Science, and an institution that is both one of the world's greatest religions and most ancient organizations. The trial has been cited both as a clear demonstration of the incompatibility between science and religion, and also a stunning exemplar of rationality, scientific method, and critical thinking. Much has been written about Galileo's trial, but most works argue from a particular point of view - that of secular science against the Church, or justifying the religious position. Maurice Finocchiaro aims to provide a balanced historical account that draws out the cultural nuances. Unfolding the intriguing narrative of Galileo's trial, he sets it against its contemporary intellectual and philosophical background. In particular, Finocchiaro focuses on the contemporary arguments and evidence for and against the Earth's motion, which were based on astronomical observation, the physics of motion, philosophical principles about the nature of knowledge, and theological principles about the authority and the interpretation of Scripture. Following both sides of the controversy and its far-reaching philosophical impact, Finocchiaro unravels the complex relationship between science and religion, and demonstrates how Galileo came to be recognised as a model of logical reasoning.

The “Galileo Affair” has been the locus of various and opposing appraisals for centuries: some view it as an historical event emblematic of the obscurantism of the Catholic Church, opposed a priori to the progress of science; others consider it a tragic reciprocal misunderstanding between Galileo, an arrogant and troublesome defender of the Copernican theory, and his theologian adversaries, who were prisoners of a narrow interpretation of scripture. In The Case of Galileo: A Closed Question? Annibale Fantoli presents a wide range of scientific, philosophical, and theological factors that played an important role in Galileo’s trial, all set within the historical progression of Galileo’s writing and personal interactions with his contemporaries. Fantoli traces the growth in Galileo Galilei’s thought and actions as he embraced the new worldview presented in On the Revolutions of the Heavenly Spheres, the epoch-making work of the great Polish astronomer Nicolaus Copernicus. Fantoli delivers a sophisticated analysis of the intellectual milieu of the day, describes the Catholic Church’s condemnation of Copernicanism (1616) and of Galileo (1633), and assesses the church’s slow acceptance of the Copernican worldview. Fantoli criticizes the 1992 treatment by Cardinal Poupard and Pope John Paul II of the reports of the Commission for the Study of the Galileo Case and concludes that the Galileo Affair, far from being a closed question, remains more than ever a challenge to the church as it confronts the wider and more complex intellectual and ethical problems posed by the contemporary progress of science and technology. In clear and accessible prose geared to a wide readership, Fantoli has distilled forty years of scholarly research into a fascinating recounting of one of the most famous cases in the history of science.
