Self-knowledge: Thomas Aquinas as critic of Augustine?

While Thomas Aquinas follows Aristotle in his doctrine of knowledge of objects, he remains largely faithful to Augustine in his views on self-knowledge. Augustine's theory of se nosse as an immediate, non-discursive self-relatedness founding all modes of reflexive self-attendance lives on in Aquinas' concept of praesentia mentis. The opposition between illumination and abstraction does not obtain here. However, Augustine ascribes a trinitarian structure to se nosse and characterises the intuitive self-consciousness as an image of divine trinity. while Thomas locates the likeness to God in the mind's discursive acts as far as they are directed towards God.
