This book examines Augustine's intellectual conversion from Platonism to Christianity, as described at Confessions 7.9.13-21.27. It is widely assumed that this occurred in the summer of 386, shortly before Augustine's volitional conversion in the garden at Milan. Brian Dobell argues, however, that Augustine's intellectual conversion did t occur until the mid-390s, and develops this claim by comparing Confessions 7.9.13-21.27 with a number of important passages and themes from Augustine's early writings. He thus invites the reader to consider anew the problem of Augustine's conversion in 386: was it to Platonism or Christianity? His original and important study will be of interest to a wide range of readers in the history of philosophy and the history of theology.
