Religious Experience and Religious Lives: An Epistemology defends a moderate approach to religious experiences in which they can contribute to the justification of central religious beliefs, most importantly belief in God. Epistemologists of religion disagree about what evidential value religious experiences have. Some argue that religious experiences have no evidential value while others argue that religious experiences constitute proof of God's existence. However, Walter Scott Stepanenko argues that religious experiences can contribute to these justificatory cases in several distinct ways and that several justificatory cases are philosophically viable. This book contends that this joint justificatory viability is best explained by the diversity and development of religious lives: as religious believers grow in a faith tradition, their access to an evidential base can develop and the contributory work religious experiences provide in defense of religious belief can change. This suggests that various epistemologies of religious experience implicitly emphasize different life stages or different prototypical religious believers and that a fully adequate epistemology of religious experience will be expansive, pluralistic, and responsive to the diversity of religious believers and their development in a religious tradition.
