The Galileo Affair

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. Thus, Scripture never errs, but its interpreters do; read rightly, Scripture and science will never conflict as 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 more than merely a hypothesis, leading to Galileo being called to trial in 1633
