The conflicting claims problem argues that the existence of mutually incompatible truth claims across religious traditions undermines the epistemic justification for any particular religious belief. The argument's inferential structure proceeds from the empirical observation that different religions make contradictory assertions about fundamental matters—the nature of ultimate reality, conditions for salvation, divine attributes, and moral imperatives—to the conclusion that religious diversity constitutes a defeater for confident religious belief. Unlike arguments that directly challenge theism, this formulation operates at the meta-level, questioning whether the fact of pervasive religious disagreement among equally sincere, intelligent, and spiritually devoted individuals should lead to epistemic humility, reduced confidence, or even suspension of judgment regarding religious truth claims.
The philosophical roots of this problem trace to David Hume's "On Miracles" (1748) and his observation that contradictory miracle claims cancel each other out. John Stuart Mill developed similar themes in "Three Essays on Religion" (1874). The contemporary formulation emerged through John Hick's "An Interpretation of Religion" (1989), which argued that conflicting truth claims point toward a pluralistic understanding. Philip Quinn and Kevin Meeker's "The Philosophical Challenge of Religious Diversity" (2000) systematized the epistemological dimensions. Richard Feldman's "Reasonable Religious Disagreements" (2007) applied peer disagreement epistemology to religious contexts. Linda Zagzebski's "Epistemic Authority" (2012) examined how religious disagreement challenges claims to religious knowledge. Recent contributions include John Schellenberg's "Religious Diversity and Religious Skepticism" (2023).
Defenders of particular religious traditions offer several responses. Alvin Plantinga in "Warranted Christian Belief" (2000) argues that if Christianity is true, believers possess a sensus divinitatis that provides warrant despite disagreement. William Lane Craig maintains that the internal witness of the Holy Spirit can override concerns about religious diversity. Islamic philosophers like Abdulkarim Soroush propose that while religious experiences vary culturally, they may point to the same transcendent reality. Critics counter that these responses beg the question by assuming the truth of particular traditions. They argue that invoking special revelation or religious experience fails to address why equally sincere believers in other traditions claim similar epistemic advantages, and that appeals to tradition-specific sources of knowledge cannot adjudicate between competing religious claims without circularity.
The conflicting claims problem differs from related formulations in focusing specifically on epistemic implications rather than soteriological or metaphysical solutions. While exclusivism maintains that one tradition possesses truth despite conflicts, and inclusivism argues that one tradition encompasses others' partial truths, the conflicting claims problem questions whether such positions can be rationally maintained given the symmetry of religious disagreement. Unlike perennialism, which posits an underlying unity beneath surface contradictions, or religious pluralism, which reinterprets contradictions as complementary perspectives, this formulation preserves the genuine incompatibility of religious claims as its starting point, arguing that this incompatibility itself constitutes the core epistemic challenge.
