Can the Mods move the appropriate posts here from 'Do Atheists believe in Logic', please? I contend that omniscience at first appears impossible because the 'knower' could always have an infinite regress of the epistemological nature- basically, always asking the self 'How do I know that I am omniscient? How do i know that there is nothing more to know?' and so on... However, it also seem that would you must have absolute knowledge to know absolutely that something is absolutely impossible. Thus, to 'know' that omniscience is impossible if self-contradictory, since such gnosticism would require omniscience. Thus, while it appears impossible, a gnostic claim of such seems fallacious.
