Anselm attempted to defend against what he saw as partly an assault on faith, with an approach allowing for both faith and reason. The Augustinian solution to the faith/reason problem is to (1) believe, and then (2) seek to understand (''fides quaerens intellectum'').

However, Grabmann's thought was instrumental in the whole modern understanding of scholasticism and the pivotal role of Aquinas.
