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.'
