Omniscience , mainly in religion, is the capacity to know everything that there is to know. In particular, Hinduism and the Abrahamic religions (Judaism, Christianity, and Islam) believe that there is a divine being who is omniscient. An omniscient point-of-view, in writing, is to know everything that can be known about a character, including past history, thoughts, feelings, etc. In Latin, omnis means "all" and sciens means "knowing".
