Social Darwinism in American Thought, 1860-1915

Social Darwinism in American Thought examines the overall influence of Darwin on American social theory and the notable battle waged among thinkers over the implications of evolutionary theory for social thought and political action. Theorists such as Herbert Spencer and William Graham Sumner adopted the idea of the struggle for existence as justification for the evils—as well as the benefits—of laissez-faire modern industrial society. Others, such as William James and John Dewey, argued that human planning was needed to direct social development and improve on the natural order.

Hofstadter''s classic study of the ramifications of Darwinism is a major analysis of the social philosophies that animated intellectual movements of the Gilded Age and the Progressive Era.
