After noting the limitations of an ‘Epistemic’ and a ‘Content’ presupposition made in recent analytical philosophy of religion, this chapter argues that philosophy has a core normative interest in religion as making metaphysical posits that support hopeful and steadfast commitment to ethical ideals. The nub of religious faith is held to be practical commitment to the foundational propositions of such religious worldviews. Philosophy, therefore, needs to seek a theory of permissible faith-commitment to putatively revealed truths for use in assessing particular forms of religious commitment. While philosophy cannot construct an ideal religion, it can, this chapter contends, develop our understanding of the cognitive content that religions need to have in order to play the identified ethical role.
