THE LIFE OF REASON is considered to be one of the greatest works by George Santayana. A five-volume study of reason, the work includes Reason in Common Sense, Reason in Society, Reason in Religion, Reason in Art, and Reason in Science. Santayana's philosophy is strongly influenced by the materialism of Democritus and the refined ethics of Aristotle, with a special emphasis on the natural development of ideal ends.
