This is the immortal justification of the Fable: that we could not teach the plainest truths so simply without turning men into chessmen. We cannot talk of such simple things without using animals that do not talk at all. Suppose, for a moment, that you turn the wolf into a wolfish baron, or the fox into a foxy diplomatist. You will at once remember that even barons are human, you will be unable to forget that even diplomatists are men. You will always be looking for that accidental good-humour that should go with the brutality of any brutal man; for that allowance for all delicate things, including virtue, that should exist in any good diplomatist. Once put a thing on two legs instead of four and pluck it of feathers and you cannot help asking for a human being, either heroic, as in the fairy tales, or un-heroic, as in the modern novels.
