Augustine wrote his famous Confessions during the early years of his episcopate, specifically, between 397 and 400. This work, ground-breaking in its time, is a piece of introspection and personal reminiscence aimed at glorifying God in gratitude for Augustine's conversion to Christianity. Augustine lays bare his personal journey, which took him from youthful carousal through phases of Manichaean dualism, Stoic speculation, skepticism, and Neo-Platonism, to the discovery of salvation in Jesus Christ. The final three "books" of this work offer Augustine's exegesis of the creation narratives in the Book of Genesis. Vernon J. Bourke (1907–1998) was a Canadian-born American professor, author, and Thomist philosopher.
