 Furthermore, Gellman has added, even if we grant that rock bottom beliefs are at times open to belief assessment, exclusivists need not engage in such assessment in the face of religious diversity unless they find that the awareness of such diversity is causing them to lose significant confidence in their own perspective. In the absence of this type of internal conflict, they “may rationally invoke [their] unreflective religious belief to defeat opposing religious claims, without having to consider the question any further” (Gellman 2000, 403).
