The critic's first duty in the presence of an author's collective works is to seek out some key to his method, some utterance of his literary convictions, some indication of his ruling theory. The amount of labour involved in an inquiry of this kind will depend very much upon the author. In some cases the critic will find express declarations; in other cases he will have to content himself with conscientious inductions. In a writer so fond of digressions as George Eliot, he has reason to expect that broad evidences of artistic faith will not be wanting. He finds in _Adam Bede_ the following passage:-- "Paint us an angel if you can, with a floating violet robe and a face paled by the celestial light; paint us yet oftener a Madonna, turning her mild face upward, and opening her arms to welcome the divine glory; but do not impose on us any æsthetic rules which shall banish from the region of art those old women scraping carrots with their work-worn hands,--those heavy clowns taking holiday in a dingy pot-house,--those rounded backs and stupid weather-beaten faces that have bent over the spade and done the rough work of the world,--those homes with their tin cans, their brown pitchers, their rough curs, and their clusters of onions. In this world there are so many of these common, coarse people, who have no picturesque, sentimental wretchedness. It is so needful we should remember their existence, else we may happen to leave them quite out of our religion and philosophy, and frame lofty theories which only fit a world of extremes.... "There are few prophets in the world,--few sublimely beautiful women,--few heroes. I can't afford to give all my love and reverence to such rarities; I want a great deal of those feelings for my every-day fellowmen, especially for the few in the foreground of the great multitude, whose faces I know, whose hands I touch, for whom I have to make way with kindly courtesy.... "I herewith discharge my conscience," our author continues, "and declare that I have had quite enthusiastic movements of admiration toward old gentlemen who spoke the worst English, who were occasionally fretful in their temper, and who had never moved in a higher sphere of influence than that of parish overseer; and that the way in which I have come to the conclusion that human nature is loveable--the way I have learnt something of its deep pathos, its sublime mysteries--has been by living a great deal among people more or less commonplace and vulgar, of whom you would perhaps hear nothing very surprising if you were to inquire about them in the neighbourhoods where they dwelt."
