2. He was ultimately found 'vehemently suspect of heresy' and placed under house arrest for the remainder of his life after being forced to recant his views.
3. The publication of 'Dialogue Concerning the Two Chief World Systems' was pivotal in his trial, as it defended heliocentrism and challenged Aristotelian cosmology.
4. The Galileo Affair highlights the conflict thesis, where science and religion are often seen as being at odds with each other throughout history.
5. In 1992, Pope John Paul II formally acknowledged the Church's errors in handling the Galileo affair, emphasizing the need for dialogue between faith and reason.

Review Questions

• How did the Galileo Affair exemplify the conflict between science and religion during its time?
  • The Galileo Affair exemplified this conflict by showcasing how scientific advancements, particularly heliocentrism, directly challenged long-held religious beliefs endorsed by the Catholic Church. The Church's response to Galileo's findings highlighted their desire to maintain authority over cosmological explanations, leading to a trial that pitted emerging scientific evidence against traditional interpretations of scripture. This case became a symbol of the broader tension between rational inquiry and doctrinal adherence during a pivotal time in history.
• Discuss the significance of the Inquisition's role in Galileo's trial and how it affected future scientific inquiry.
  • The Inquisition's role in Galileo's trial was significant because it represented the institutional power of the Church in regulating thought and suppressing dissenting ideas. By condemning Galileo's work, the Inquisition instilled fear among scientists and thinkers, leading to self-censorship and hesitance in exploring controversial ideas. This suppression had long-lasting effects on scientific inquiry, causing a divide where future scientists often felt pressured to align their findings with religious doctrines to avoid persecution.
• Evaluate how the resolution of the Galileo Affair has influenced contemporary discussions about science and religion.
  • The resolution of the Galileo Affair has significantly influenced contemporary discussions about science and religion by serving as a cautionary tale regarding dogmatism and intellectual freedom. The eventual acknowledgment by Pope John Paul II of the Church's mistakes illustrates a shift towards reconciling faith with scientific understanding. This recognition encourages ongoing dialogue between these two realms today, suggesting that rather than being inherently opposed, science and religion can inform one another when approached with openness and mutual respect.
