1863 – 1952
George Santayana (1863–1952) was a Spanish-American philosopher, poet, and cultural critic who taught at Harvard before retiring to Europe. He developed a naturalistic metaphysics grounded in materialism while maintaining a rich aestheticism, arguing that values and ideals are humanly constructed yet genuinely significant. His work spans epistemology, aesthetics, ontology, and the philosophy of religion.
Developed a systematic naturalist ontology across the four-volume Realms of Being (essence, matter, truth, spirit)
Authored The Sense of Beauty (1896), one of the first systematic treatises on aesthetics in American philosophy
Articulated 'animal faith' as the basis of knowledge in Scepticism and Animal Faith (1923)
Produced The Life of Reason (1905–1906), a naturalistic account of reason across society, religion, art, and science
Coined the aphorism 'Those who cannot remember the past are condemned to repeat it'
