Abstract
John Abbruzzese has recently attempted a defense of omniscience against a series of my
attacks. This affords me a welcome occasion to clarify some of the arguments, to pursue some
neglected subtleties, and to re-think some important complications. In the end, however, I must
insist that at least three of four crucial arguments really do show an omniscient being to be
impossible. Abbruzzese sometimes misunderstands the forms of the argument themselves, and
quite generally misunderstands their force.
