George Santayana, born Jorge Augustín Nicolás Ruiz de Santayana (1863–1952), was a Spanish-American philosopher, novelist, poet, and essayist. He is best known for his witty aphorisms, especially the phrase, “Those who cannot remember the past are condemned to repeat it.” Santayana was born in Spain, but was raised and educated in the United States. He attended Harvard College and later taught philosophy there. During this time he wrote many of his seminal philosophical works, including The Sense of Beauty, The Life of Reason, and The Realms of Being. In 1912, Santayana moved to Europe, where he devoted his life to writing both fiction and nonfiction.
