Episteme
True knowledge based on demonstration and understanding of causes — as opposed to mere opinion.
The Meaning of Episteme
Episteme was certain, demonstrable knowledge — what Athena possessed when she guided heroes, and what Apollo dispensed through the Oracle at Delphi. It stood above doxa (opinion) and below sophia (divine wisdom). Prometheus gave humanity the capacity for episteme when he stole fire — the ability to know and understand the world. Asclepius achieved such episteme in medicine that he could raise the dead, crossing the boundary between mortal knowledge and divine prerogative. Zeus destroyed him for it — episteme has limits even the gods enforce.

Fun Fact
Foucault's use of "episteme" in The Order of Things became one of the most influential concepts in 20th-century humanities — ironic, given that Aristotle would barely recognise his usage.
