Hello everyone,
 
I've recently became interested in Augustine's contribution to medieval and post-medieval accounts of necessity, in particular through his speculation on God's capacity to have created alternative world-histories. Would anyone know of decent overview of his metaphysics which goes into this area in some depth?
 
P.S. In case it should be mentioned: I am aware of Gareth B Mathews’ small Augustine volume but don’t wholly trust the man, so am thus far avoiding it.
