THE Tale, the Parable, and the Fable are all common and popular modes of conveying instruction. The Tale is a story either founded on facts, or sometimes just a figment of imagination. There are no moral lessons expected to be learned. The Parable is intended to convey secret meanings. Fables are intended to impact human behavior through the stories and the characters. Good and bad characters are clearly demarcated. Aesops fables have become a part of our everyday language. The story of the thirsty crow dropping pebbles in a pitcher to raise up the level of water is one of the first lessons in innovation we learned. The moral of the story is explicitly stated at the end eg "Necessity is the mother of invention" in case of the Crow and the Pitcher story.
