Novelties in the Heavens
Rhetoric and Science in the Copernican Controversy
Moss describes the nature of dialectical and rhetorical discourse in the period of the Copernican debate to shed new light on the argumentative strategies used by the participants. Against the background of Ptolemy's Almagest, she analyzes the gradual increase of rhetoric beginning with Copernicus's De Revolutionibus and Galileo's Siderius nuncius, through Galileo's debates with the Jesuits Scheiner and Grassi, to the most persuasive work of all, Galileo's Dialogue. The arguments of the Dominicans Bruno and Campanella, the testimony of Johannes Kepler, and the pleas of Scriptural exegetes and the speculations of John Wilkins furnish a counterpoint to the writings of Galileo, the centerpiece of this study.
The author places the controversy within its historical frame, creating a coherent narrative movement. She illuminates the reactions of key ecclesiastical and academic figures figures and the general public to the issues.
Blending history and rhetorical analysis, this first study to look at rhetoric as defined by sixteenth- and seventeenth-century participants is an original contribution to our understanding of the use of persuasion as an instrument of scientific debate.
