On June 22, 1633, the Roman Catholic Church forced Galileo Galilei to renounce his view that the Earth rotates around the Sun. By doing so, he avoided death and was instead placed on house arrest. The Church opposed the heliocentric model, proposed by Copernicus a century before, because it directly contradicted biblical passages that assumed a geocentric system.
In Ideas of Liberty in Early Modern Europe: From Machiavelli to Milton, Hilary Gatti argues that the early modern period laid the foundations of our modern ideas of liberty, justice, and democracy. The “Galileo affair” is one example of this process that she highlights. Gatti argues that this moment in history has become “the historical pivot around which one of the most heated discussions of our time is developing—that is, how far religious doctrine can, if at all, determine the inquiries of the scientists and the ways in which they are accepted by society and taught in its academies and schools” (104). We see this debate continuing in our own time surrounding the study of the Theory of Evolution in schools.
