The Life of Reason: The Phases of Human Progress

Philosopher George Santayana published The Life of Reason in five volumes between 1905 and 1906. Said to be the most fully-realized articulation of Santayana's moral philosophy, the volumes of this set are Reason in Common Sense, Reason in Society, Reason in Religion, Reason in Art, and Reason in Science; all contained in this edition. Considered by many to be one of the more well-written and poetic works in Western philosophy, The Life of Reason gives us the often-quoted "those who cannot remember the past are condemned to repeat it."
