After the surprising publishing success of the so-called New Atheists it has become clear that there is a market for critical discussions about religion. A religion is much more complex than a set of beliefs which cannot be proven, as the New Atheists argue. There is, in fact, much more to religion and much more to the arguments about its truth claims. This book seeks to bring together a range of discussions, both critical and apologetic, each of which examines some part of religion and its functions. Half of the contributors are critical of some element of religion and the other half are apologetic in nature, seeking to defend or extend some particular religious argument. Covering a wide range of topics, including ethics, religious pluralism, the existence of God, and reasonableness of Islam, these pieces have in common arguments that are made in careful and scholarly ways—they represent reasonable perspectives on a wide swath of contemporary religious debates, in contrast to the unreasonableness that creeps into discussions on religion in American society.
