Morais, H. M. _Deism in Eighteenth Century America._ New York: 1934. (If little space is given to the implications of Deism in terms of political, economic, and literary theory, and if the leaders of deistic thought, such as Franklin, Jefferson, and Paine are too lightly dealt with, this work is "substantial, precise, well-documented, modest, cautious, and objective." Has a good bibliography. Reviewed by H. H. Clark, _American Literature_, VI, 467-9, Jan., 1935. See also Morais's "Deism in Revolutionary America, 1763-89," _International Journal of Ethics_, XLII, 434-53, July, 1932.)

Brinton's review, _American Historical Review_, XXXIX, 726-7, 1934.)
