Can God's nonexistence be established by good, clear, objective evidence? It all depends on what is meant by "God." This book expands the frontiers of philosophy by exploring this nest of issues in more detail than ever before, while presenting a strong case for atheism.

The two major arguments in support of nonexistence, the more established Argument from Evil and the recent Argument from Nonbelief, are explored individually and in parallel development while defending both against the strongest objections.
Included are examinations of the free-will problem, the possibility of an afterlife, arguments by theists, and positive atheism. Drange also discusses specific concepts of the duty e.g. of evangelical and liberal Christianity, and orthodox Judaism to demonstrate how theological and atheological arguments depend upon the conception of God one accepts.
