With their website, Investigating Atheism, the University of Cambridge hopes to add some clarity to the subject. Despite the attention recent books on atheism have received, they have had a mixed reception from the religious communities and from fellow atheists and agnostics. The goal of the site is to "set these contemporary "God Wars" in their historical context, and to offer a range of perspectives (from all sides) on the chief issues raised by the new atheists." A good place to start exploring this very well organized website is by looking in the Selected Features box on the right side of the homepage. There, a visitor can get an overview of the issues and the players, by clicking on "Current Controversies", "Atheist Politics", "Atheism and Meaning", "Arguments for Disbelief", and "Links". The "Links" section is divided up between Atheistic/Humanistic and Responses to the Debate. Visitors will find that studying atheism can be more complicated than it seems. The "History" tab points out the difficulty in recounting the history of atheism, because there is disagreement over its beginnings and players. Click on "Demographics" on the left side of the page to read about the obstacles faced when trying to get an accurate count of the number of atheists in the world today. Imperfect data is available, however, and such data suggests between 500 million and 750 million people don't believe in God.
