New York: 1927. (Contains useful "Critical Essay on Authorities" consulted, pp. 324-56, which serves as a guide for further study of many phases of the social history of the period.) Adams, R. G. _Political Ideas of the American Revolution._ Durham, N. C.: 1922. Andrews, C. M. _The Colonial Background of the American Revolution._ New Haven: 1924. (Stresses economic factors and the need of viewing the subject from the European angle; profitably used as companion study to Beer's _British Colonial Policy_.) Baldwin, Alice M. _The New England Clergy and the American Revolution._ Durham, N. C.: 1928. (Prior to 1763 the clergy popularized "doctrines of natural right, the social contract, and the right of resistance" and principles of American constitutional law.) Beard, C. A. _The Economic Origins of Jeffersonian Democracy._ New York: 1915. (Suggestive, if _other_ factors are not neglected. See C. H. Hull's review in _American Historical Review_, XXII, 401-3.) Becker, Carl. _The Declaration of Independence; A Study in the History of Political Ideas._ New York: 1922. (Excellent survey of natural rights, and the extent to which this concept was influenced by Newtonianism.) Becker, Carl. _The Heavenly City of the Eighteenth-Century Philosophers._ New Haven: 1932. (R. S. Crane observes, after calling attention to certain obscurities and confusions: "The description of the general temper of the 'philosophers,' the characterization of the principal eighteenth-century historians, much at least of the final chapter on the idea of progress--these can be read with general approval for their content and with a satisfaction in Becker's prose style that is unalloyed by considerations of exegesis or terminology" [_Philological Quarterly_, XIII, 104-6].)
