Divine Omniscience: Complete Knowledge or Supreme Knowledge?

One of the divine attributes is omniscience. The standard concept of omniscience is the concept of having complete knowledge: God knows every truth. But there are also other concepts of omniscience that are consistent with having incomplete knowledge. I will propose a new concept of omniscience, namely the concept of having supreme knowledge. It is inspired by how Anselm talks about God's knowledge and it makes good sense of a key premise in an Anselmian argument for omniscience. Moreover, it can be used to escape some of the set-theoretical and logical arguments against divine omniscience.
