The Enlightenment valued reason and evidence-based thinking independent of tradition. Voltaire was a key figure who advocated for freedom of thought and religion. Neo-Classicism drew from Greek and Roman art, emphasizing emotionless figures and narratives, as seen in David's Oath of the Horatii. Romanticism valued personal freedoms and feelings over reason, as expressed through Blake's visionary works and Goya's nightmare imagery critiquing the horrors of war.
