Is there a God? is one of those irrepressible questions that has been debated throughout human history, with scholars from opposites camps making the case for or against the existence of God. It is a never-ending debate. This book first examines the theistic arguments developed by Islamic scholar Saïd Nursi in the twentieth century. Although his arguments initially seem to be mere presentations of well-established theistic arguments for Godsuch as teleological and cosmological, and arguments from miracles and moralsit is clear that Nursi takes a fresh approach to these existing philosophical defences. The book then analyses how Nursi tackles certain atheistic argumentssuch as the problem of evil and the possibility of existence without a creatorand criticism leveled against the prophets and the Quran.
