How we cite our quotes: All quotations are from Pinocchio.
Quote #1
THE BLUE FAIRY: Prove yourself brave, truthful, and unselfish and someday you will be a real boy.
Pinocchio is built around a very simple proposition—that Pinocchio will become a real human being if he proves himself to have a good heart. Unfortunately for our stringless friend, however, it can be quite hard to stay on the straight and narrow.
Quote #2
THE BLUE FAIRY: You must learn to choose between right and wrong.
PINOCCHIO: Right and wrong? But how will I know?
THE BLUE FAIRY: Your conscience will tell you.
This passage shows how naive Pinocchio is. He's basically a one-day-old baby who was magically granted the power of speech, after all, so he utterly lacks the discipline and judgement needed to tell right from wrong.
Quote #3
JIMINY: A conscience is that still, small voice that people won't listen to. That's just the trouble with the world today.
It's worth noting that Jiminy isn't necessarily being one-hundred-percent sincere here—he's just trying to score himself some brownie points with the lovely Blue Fairy. In fact, this dynamic becomes an important part of Jiminy's own moral growth over the course of the film.
