Why did the philosophes alienate themselves from the Church?

The philosophes alienated themselves from the Church primarily due to its dogmatic authority and opposition to reason and scientific inquiry. They championed Enlightenment ideals such as rationalism, individualism, and skepticism of traditional beliefs, which often clashed with religious doctrines. Additionally, the Church's historical role in perpetuating social injustices and censorship further fueled their desire to advocate for secularism and reform. As a result, many philosophes sought to promote a worldview based on reason and empirical evidence rather than faith.
