Did autodidacts found Western Culture?
The first occurrence of the word "autodidact" (αὐτοδίδακτος) is in Homer's Odyssey.
It's book 22, Odysseus has just slaughtered the suitors.
The bard Phemius "who sang for them under compulsion," emerges from hiding to plead for his life.
He makes his case while holding Odysseus by the knees (suppliant style).
His claim to be "self taught" is not a plea for pity ("I couldn't afford an MFA degree!") but rather a suggestion of his divine inspiration.
Telemachus turns to his dad, and backs up Phemius "Leave the bard be, he's one of the good ones".
Phemius lives.
Before universities and degree programs and schools, artists (and intellectuals) were credentialed on competence alone.
You could tell if the Muse was with them or not.
