The last book of the City of God includes a long chapter which treats the original good, a text which follows other chapters dealing with the original evil. The present article studies this little known chapter, in which Augustine examines «profane» human values: the good as regards the soul, the body and the universe. It then proposes other Augustinian texts concerning the pagans and their salvation and «profane» virtues. Finally it appraises a correspondence between Augustine and Longinianus, a pagan priest in Rome.
