Omniscience: All knowledge. Infinite awareness, understanding, and insight. Someone who (supposedly) possesses omniscience is omniscient. From the Latin "omni-" (all) + "scire" (to know) = to know all.
Medical students and nursing students would do well to recall what Francis Bacon said a while back (about 1615), "By no means trust to your own judgement alone; for no man is omniscient."
