George Santayana 
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."
