The Enlightenment challenged religious authority, promoting reason and individual rights. Thinkers like Voltaire and Rousseau advocated for religious tolerance and separation of church and state. This period saw a rise in secularism and critiques of religious dogma in literature. Romanticism emerged as a reaction to Enlightenment rationalism, emphasizing emotion and imagination. Romantic writers explored religious themes through nature, mythology, and individual spiritual experiences. They often used biblical allusions and religious symbolism to convey deeper truths about the human condition.
