The play of _King Lear_ is based upon a fable and a fairy story. It illustrates the most terrible forms of treachery, that of child against father, and father against child. It is the most affecting and the grandest of the plays. The evil which makes the action springs from two sources, both fatal. One is the blindness or fatuity in Lear, which makes him give away his strength and cast out Cordelia. The other, equally deadly, but more cruel in its results, springs from an unrepented treachery, done long before by Gloucester, when he broke his marriage vows to beget Edmund. Memory of the sweetness of that treachery gives to Gloucester a blindness to the boy's nature, just as a sweetness, or ease, in the treachery of giving up the cares of kingship (against oath and the kingdom's good) helps to blind Lear to the natures of his daughters. The blindness in the one case is sentimental, in the other wilful. Being established, fate makes use of it. One of the chief lessons of the plays is that man is only safe when his mind is perfectly just and calm. Any injustice, trouble or hunger in the mind delivers man to powers who restore calmness and justice by means violent or gentle according to the strength of the disturbing obsession. This play begins at the moment when an established blindness in two men is about to become an instrument of fate for the violent opening of their eyes. The blindness in both cases is against the course of nature. It is unnatural that Lear should give his kingship to women, and that he should curse his youngest child. It is unnatural that Gloucester should make much of a bastard son whom he has hardly seen for nine years. It is deeply unnatural that both Lear and Gloucester should believe evil suddenly of the youngest, best beloved, and most faithful spirits in the play. As the blindness that causes the injustice is great and unnatural, so the working of fate to purge the eyes and restore the balance is violent and unnatural. Every person important to the action is thrust into an unnatural way of life. Goneril and Regan rule their father, commit the most ghastly and beastly cruelty, lust after the same man, and die unnaturally (having betrayed each other), the one by her sister's hand, the other by her own. Lear is driven mad. The King of France is forced to war with his wife's sisters. Edmund betrays his half-brother to ruin and his father to blindness. Cornwall is stabbed by his servant. Edgar kills his half-brother. Gloucester, thrust out blind, dies when he finds that his wronged son loves him. Cordelia, fighting against her own blood, is betrayed to death by one who claims to love her sisters. The honest mild man, Albany, and the honest blunt man, Kent, survive the general ruin. Had Kent been a little milder and Albany a little blunter in the first act, before the fates were given strength, the ruin would not have been. All the unnatural treacherous evil comes to pass, because for a few fatal
