At the end of the Reconstruction, the spread of science and technology, industrialism, urbanization, immigration, and economic depressions eroded Americans' conventional beliefs in individualism and a divinely ordained social system. In The Search for Order, Robert Wiebe shows how, in subsequent years, during theProgressive Era of Theodore Roosevelt and Woodrow Wilson, Americans sought the organizing principles around which a new viable social order could be constructed in the modern world. This subtle and sophisticated study combines the virtues of historical narrative, sociological analysis, and social criticism.
