A related idea emerges from the suggestion that not only does a perfect being exist necessarily, but it has its various great-making properties of necessity. The suggestion is that a being worthy of worship should not “possess its various excellences in some merely adventitious manner” (Findlay 1948: 180). In that case, another feature of divine knowledge, if God exists necessarily, is being essentially omniscient, that is, being omniscient and not possibly lacking omniscience. Essential omniscience entails infallibility—a being who could not possibly fail to be omniscient could not possibly be mistaken—but the reverse does not hold, for a being who could not possibly believe a falsehood might nevertheless fail to believe all truths. So essential omniscience might be another additional component to the standard account. In an influential article Pike (1965) has argued for the incompatibility of essential omniscience and voluntary human action (see Section 3).
