Quote by Charles Hodge

“This is the foundation of the distinction between the scientia necessaria and the scientia libera. God knows Himself by the necessity of his nature; but as everything out of Himself depends for its existence or occurrence upon his will, his knowledge of each thing as an actual occurrence is suspended on his will, and in that sense is free. Creation not being necessary, it depended on the will of God whether the universe as an object of knowledge should exist or not.”
