A well-known objection to divine simplicity holds that the doctrine is incompatible with God’s contingent knowledge. I set out the objection and reject two problematic solutions. I then argue that the objection is best answered by adopting an “extrinsic model of divine knowing” according to which God’s contingent knowledge, which varies across worlds, does not involve any intrinsic variation in God. Solutions along these lines have been suggested by others. This paper advances the discussion by developing and offering partial defenses (...) of three such models. (shrink)
