The Life of Reason, all five volumes in a single file

According to Wikipedia: "George Santayana (born Jorge Agustín Nicolás Ruiz de Santayana y Borrás in Madrid, December 16, 1863; died September 26, 1952, in Rome) was a Spanish American philosopher, essayist, poet, and novelist. A lifelong Spanish citizen, Santayana was raised and educated in the United States. He wrote in English and is generally considered an American man of letters. However, in his early fifties, Santayana left his position at Harvard and moved to Europe, never to return to the United States. His last will was to be buried in the Spanish Pantheon in Rome. Santayana is perhaps best known today for his remark that "Those who cannot remember the past are condemned to repeat it", and the line "only the dead have seen the end of war"—the latter often falsely attributed to Plato. The philosophical system of Santayana is broadly considered Pragmatist due to having similar concerns as his fellow Harvard University associates William James and Josiah Royce, but he did not accept this label for his writing and eschewed any association with a philosophical school; he declared that he stood in philosophy "exactly where [he stood] in daily life."
