Advertisement to the Reader on the Following Treatise. on marriage and concupiscence. These books are entitled, On Marriage and Concupiscence .
Conjugal chastity makes a good use of the evil of concupiscence in the procreation of children.
My first treatise contained two books. The first of them found its way into the hands of Julianus the Pelagian, who wrote four books in opposition to it. I wrote a second book in answer to these extracts. On revising these two Books, which he addressed to the Count Valerius, Augustin placed them immediately after his reply to the discourse of the Arians, which was affixed to the Proceedings with Emeritus . Now these proceedings are stated to have taken place on the 20th of September, in the year of our Lord 418.
