What went wrong? Does the Galileo affair represent an inevitable conflict between science and religion?
Sometimes in harmony, sometimes in conflict, science and religion interact in diverse and historically contingent ways. The Galileo Affair turns out to be more complicated than a simple conflict of science and religion. It stands as a paradigmatic example of a controversy where novel methodologies challenge established disciplines within an authoritarian social and political context. In a tumultuous time, Galileo challenged the established and reputable domains of physics and theology, both of which underestimated the knowledge claims of the new mathematical science.
“If, against the most manifest and reliable testimony of reason, anything be set up claiming to have the authority of Holy Scriptures, he who does this does it through a misapprehension of what he has read and is setting up against the truth not the real meaning of Scripture, which he has failed to discover, but an opinion of his own; he alleges not what he has found in the Scriptures, but what he has found in himself as their interpreter.” Galileo, Letter to the Grand Duchess Christina (quoting Augustine; 1615), trans. Maurice Finocchiaro
Section 1: The Bible and Science
The religious and political conflicts of the Reformation and Counter-Reformation evoked passionate and widespread controversies over the meaning of the Bible. Would new discoveries in science throw additional fuel on these fires? Both Catholic and Protestant traditions accepted, in principle, the idea that Scripture passages are accommodated to ordinary human understanding. Practical application of this principle, however, was complicated by longstanding traditions of interpretation. Natural philosophers might face mortal hazards when writing about theological topics. Yet in other cases, scriptural passages also prompted, motivated, shaped and helped legitimize scientific inquiry.

Section 2: Galileo and the Church
In the Letter to the Grand Duchess Christina, Galileo argued that the purpose of Scripture is to tell us how to go to heaven, not how the heavens go; Scripture never errs, but its interpreters do err; and read rightly, Scripture and science will never conflict (there is a unity of truth). That which is obscure (figurative language) should be explained by that which is clear (mathematical demonstrations). Nevertheless, Galileo’s Dialogue on the Two Chief Systems of the World overstepped the expected boundaries for a mathematician by arguing that Copernicanism was physically true and certain rather than merely hypothetical, and Galileo was called to trial in 1633.
