What is the theme in Zero: The Biography of a Dangerous Idea by Charles Seife?

Zero and theology is another theme. While Zero: The Biography of a Dangerous Idea is primarily a story of the progress of science and mathematics, it is also a story about theology, particularly a theology of creation and apocalypse. Zero is associated with the idea of a void, the idea of beginning and the idea of death and destruction. As such, zero is bound to evoke theological questions. Seife argues that it was fear of finding particular answers to these questions that prevented the Greeks, Romans and Medieval Roman Catholics from accepting zero.
