A major representative of the German sociological tradition, Georg Simmel (1858-1918) has influenced social thinkers ranging from the Chicago School to Walter Benjamin. His magnum opus, The Philosophy of Money, published in 1900, is nevertheless a difficult book that has daunted many would-be readers. Gianfranco Poggi makes this important work accessible to a broader range of scholars and students, offering a compact and systematically organized presentation of its main arguments. Simmel's insights about money are as valid today as they were a hundred years ago. Poggi provides a sort of reader's manual to Simmel's work, deepening the reader's understanding of money while at the same time offering a new appreciation of the originality of Simmel's social theory.
