Hebert Spencer coined the famous expression �survival of the fittest�.

Spencer�s theory inspired Andrew Carnegie and William Graham Sumner's visions of unbridled and unrepentant capitalism of the United States in late nineteenth-century. Carnegie interpreted Spencer's social theory as justifying merciless economic competition.

Spencer's reputation was not recovered for many years from the interpretative caricatures of many scholars, thus marginalizing him to the hinterlands of intellectual history. Fortunately, recent scholarship has begun restoring and repairing his legacy and theory.

This is a must book for readers who are interested in studying and correctly interpreting Spencer�s theory that can be simply coined by him as �survival of the fittest�.
