If we were to describe a man as deceitful, drunken, cowardly, dishonest, boastful, unscrupulous, gluttonous, vainglorious, lazy, avaricious, and selfish, we should hardly leave room in him for good qualities. No one would take it as a compliment to be described in this way, and we would avoid a person described in such a fashion. Falstaff was all those things, but probably no character in all literature is better loved. Only Don Quixote can compete; and our love of Falstaff is not despite his roguery but because of it. Certainly we would rather spend an evening in his company than with the totally upright Lord Chief Justice of Part 2 of Henry IV. A world of such rectitude, in which everyone had the justice’s probity, would be better, no doubt: but it would not be much fun.
