The subject of this essay is the concept of omnisubjectivity, which is a form of omniscience introduced by Linda Zagzebski. I will analyse the concept in detail, its possible implications, objections and further developments and critically examine these.      Omnisubjectivity is the idea that God has constant access to our consciousness and all our mental states and that God can grasp all conscious creatures’ first-person perspectives at the same time as God has his own first- and third-person perspective. As a model for this Zagzebski uses human empathy, where she means that God has perfect total empathy which implies that God has constant access to all our mental states at the same time as God never forgets that those mental states aren’t God’s own.      Some of the possible implications that I bring up in this essay are that omnisubjectivity can explain how God hears prayers, how God’s love and providence can deepen, how God might or might not be affected by humans’ mental states, especially their failings and immoral actions and thoughts, and how God’s judgement can be perfectly fair. The objections concern Zagzebski’s use of empathy as a model for omnisubjectivity, the definition of perfection, God’s relation to time and what the first-person perspective contributes to. The developments concern Thomas Aquinas thought of God as everything’s first cause and christology.      This essay’s conclusion is that omnisubjectivity is, to a large extent, already a part of omniscience, but that it also contributes with new aspects and opens up for new questions and deepens the meaning of omniscience and God’s relation to his created creatures.
