Cavadini on Augustine on eros and marriage

Here's another Augustine-related link. This one is to "The Sacramentality of Marriage in the Fathers," by Notre Dame's John Cavadini. A short excerpt:

To Augustine’s mind, there is something naïve about a view of marriage that treats sexual desire as a relatively uncomplicated eros which education and ascetic living can easily channel into the pleasures of home and family. For Augustine, sexual desire as we know it now is anything but uncomplicated. To people accustomed to thinking that sexual desire and the pleasure it seeks are obvious and uncomplicated goods that contribute, in a straightforwardly positive way to the bonding and happiness of a married couple, Augustine’s views will look pessimistic. Yet Augustine would probably insist that it is simply realistic. Sexual pleasure is not a fixed quantity, unambiguously and obviously good as we experience it in a fallen world.
