Stillman Drake investigates whether the trial and condemnation of Galileo were driven by ecclesiastical conflict or by the professional hostility of contemporary Aristotelian philosophers. Drawing on his extensive expertise in the history of science, Drake re-examines the primary source evidence to argue that Galileo’s scientific methodology—focused on mathematical laws rather than Aristotelian causes—created an irreconcilable rift between the emerging field of physics and traditional philosophy.

Experts recognize this text as a significant contribution to the historiography of science, particularly for its focus on the methodological shift in physics. Readers frequently note the academic density of the prose, which assumes a foundational understanding of the period's intellectual climate.
