Who wrote "Show me the heart unfettered by foolish dreams…And I'll show you a happy man." ?
It was spoken by George McAllister (=the character name of the Latin teacher "the Realist" in Dead Poets Society).
Some says that it could be Alfred Lord Tennyson, but can someone confirm this and state the precise publication?
Here is the transcript from the film:
McAllister: You take a big risk by encouraging them to be artists, John. When they realize they're not Rembrandts, Shakespeares or Mozarts, they'll hate you for it.
Keating: We're not talking artists, George, we're talking freethinkers.
McAllister: Freethinkers at seventeen?
Keating: Funny — I never pegged you as a cynic.
McAllister: Not a cynic, a realist. "Show me the heart unfettered by foolish dreams, and I'll show you a happy man."
Keating: "But only in their dreams can men be truly free. 'Twas always thus, and always thus will be."
Keating: No, Keating.
