In the book the author explains that thinkers throughout human history have tried to find out the ultimate purpose of creation. The Quran explains that God created an ideal world called Paradise. To select ideal human beings to inhabit Paradise, He created the present Earth as a selection ground and settled man here, giving him complete freedom. Here, it is being observed as to who makes proper use of his freedom and who misuses it. At the end of human history, those who have abused their freedom will be rejected, and those who may have exercised it judiciously will be selected by God to be lodged in eternal Paradise. The concept of Paradise is, therefore, a beautiful interpretation of human history.
