 Clarke’s rationalism is tempered by his discussions of faith in reason, especially in his writings against the Deists. Against the Deists, who generally expected all necessary moral and religious truths to be discoverable by reason, Clarke asserted that revealed religion (also called special revelation) provided information necessary for salvation (W 2.666–667). While special revelation involved “supplying the deficiencies” of “right reason,” it could not contradict reason (W 2.669).
