Fabulists as censors have always been not only tolerated, but patronized and encouraged, even in the most despotic countries, and when they have exposed wickedness and folly in high places with an unsparing hand. Æsop among the ancients, and Krilof amongst the moderns, are both striking examples of this. The fables of antiquity may indeed be truly said to have been a natural product of the times in which they were invented. In the early days, when free speech was a perilous exercise, and when to declaim against vice and folly was to court personal risk, the fable was invented, or resorted to, by the moralist as a circuitous method of achieving the end he desired to reach--the lesson he wished to enforce. The entertainment afforded by the fable or apologue took off the keen edge of the reproof; and, whilst the censure conveyed was not less pointed and severe, the device of making the humbler creatures the scapegoat of human weakness or vice mollified its bitterness. The very indirectness of the fable had the effect of making the sinner his own accuser. Whom the cap fitted was at liberty to don it. Phædrus, in the prologue to his third book, thus gives his view of the origin and purpose of fables: 'Here something shortly I would teach Of fables' origin. To reach The potent criminal, a slave To beasts and birds a language gave. Wishing to strike, and yet afraid, Of these his instruments he made: For all that dove or lamb might say, Against them no indictment lay.'[13] The fable saves the self-love of the person to whom it is applicable. It enables him to stand aside, as it were, and become a spectator of the effect produced by his own conduct. In this way he is impressed and humbled without being affronted. When one, even though guilty, is openly and directly reproved for a misdeed, the stigma often raises a rebellious spirit, which either suggests a hundred justifiable reasons for his action or begets a defiant mood, driving him to persist in his evil courses.
