experience. Santayana presents the idea that existence is marked by a chaotic order, which the human mind attempts to make sense of through reflective thought. He introduces the concept of "the Life of Reason" as a synthesis of impulse and thought, emphasizing that true progress must involve a rational understanding coupled with the evaluations of our experiences.
