God knows all things. . . . The things...

God knows all things. . . . The things he knows are partly divine and immortal, partly perishable and temporal. . . . His knowledge of uncertain things . . . cannot be different from their nature. . . . They are . . . possible in both directions rather than subject to necessity. . . . So contingent things are not inflexibly arranged and determined from the beginning with the sole exception of the very fact, that they must be uncertain.
