Book excerpt: The Study of Ambition is the eighty-sixth instalment in the Little Blue Book Series and comprises the first and second discourses of the Pentadoxy, which is itself the fifth disquisition of the Omnidoxy, Astronism’s founding book. This publication firstly introduces the inclusive discipline of xentology which encompasses both the study and philosophisation of ambition and enlightenment. This is followed by an exploration of the concept of ambition from the perspective of Astronism, particularly highlighting the importance of ambition in the Astronist belief system. The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
