“But if the miracle is not thought as violence, if the opposition between violence and nature is suspended, it is because the Augustinian concept of nature considerably weakens the Aristotelian notion of physis. It is because miracle and nature are both referred back to [Augustine’s] concept of seminal reason, and are only distinguished as the inhabitual and the habitual.”
“In effect, just as the miracle can be called an inhabitual order, in the same way, in the final analysis, order is only a miracle to which one is habituated” (Gwenaëlle Aubry, Genèse du dieu souverain, p. 73, my translation). Augustine’s position is rhetorically more moderate and balanced than those of later occasionalists and theological voluntarists; but Aubry’s point is that when pushed, it leads to the same conclusions. She notes that Augustine’s use of “seminal reasons” is quite different from that of the Stoics; in Augustine, they are referred back directly to the creative power of God.
Augustine never calls God’s will arbitrary; on the contrary, he calls it good and just. But once having put the power of God first in the order of explanation — ahead of goodness and justice — he can only save God’s goodness and justice by invoking mystery, which is to renounce the intelligibility of the good.
