Abstract
Classical and Post-Classical Philosophy in the Greek tradition played powerful roles in the formation of philosophical, scientific and theological thought by thinkers in the religious and cultural milieux of Judaism, Christianity, and Islam. Yet the scriptures, theologies, and fundamental concerns of these Abrahamic religious traditions reciprocally enriched the development of religious thought and secular philosophy and science by prompting ethical, metaphysical, and epistemological questions that have continued to challenge philosophers and theologians up to the present day. While political conflicts of the twentieth and twenty-first centuries have led to a public emphasis on distinctions and differences between these faiths, the history of philosophy shows that thinkers of each tradition over the centuries share in the common purpose of seeking to conciliate in a variety of ways the principles and insights of religious beliefs with the truths of secular natural reason into a coherent worldview
