THE TALES, The Parables and The Fables are all common and popular modes of conveying instruction. Each is distinguished by its own special characteristics.
The Tale consists simply in the narration of a story either founded on facts or created solely by the imagination and not necessarily associated with the teaching of any moral lesson.
The Parable is the designed use of language purposely intended to convey a hidden and secret meaning other than that contained in the words themselves and which may or may not bear a special reference to the hearer or to the reader.
The Fable partly agrees with and partly differs from both of these. It will contain, like the Tale, a short but real narrative. It will seek, like the Parable, to convey a hidden meaning and that not so much by the use of language, as by the skilful introduction of fictitious characters.
And yet unlike to either Tale or Parable, it will ever keep in view, as its high prerogative and inseparable attribute, the great purpose of instruction and will necessarily seek to inculcate some moral maxim, social duty or political truth. The true Fable, if it rise to its high requirements, ever aims at one great end and purpose representation of human motive and the improvement of human conduct and yet it so conceals its design under the disguise of fictitious characters, by clothing with speech the animals of the field, the birds of the air, the trees of the wood or the beasts of the forest, that the reader shall receive advice without perceiving the presence of the adviser.
Thus the superiority of the counsellor, which often renders counsel unpalatable, is kept out of view and the lesson comes with the greater acceptance when the reader is led, unconsciously to himself, to have his sympathies enlisted on behalf of what is pure, honorable and praiseworthy and to have his indignation excited against what is low, ignoble and unworthy. The true fabulist, therefore, discharges a most important function. He is neither a narrator nor an allegorist. He is a great teacher, a corrector of morals, a censor of vice and a commender of virtue. In this consists the superiority of the Fable over the Tale or the Parable. The fabulist is to create a laugh, but yet, under a merry guise, to convey instruction. Phaedrus, the great imitator of Aesop, plainly indicates this double purpose to be the true office of the writer of fables.
