he always took a strong intellectual interest in the problems of medieval theology; but he became steadily and quietly independent in his philosophic outlook and indeed rather skeptical of all definite dogmas. Even in his art Chaucer's lack of the highest will-power produced one rather conspicuous formal weakness; of his numerous long poems he really finished scarcely one. For this, however, it is perhaps sufficient excuse that he could write only in intervals hardly snatched from business and sleep. In 'The Canterbury Tales' indeed, the plan is almost impossibly ambitious; the more than twenty stories actually finished, with their eighteen thousand lines, are only a fifth part of the intended number. Even so, several of them do not really belong to the series; composed in stanza forms, they are selected from his earlier poems and here pressed into service, and on the average they are less excellent than those which he wrote for their present places (in the rimed pentameter couplet that he adopted from the French). 2. _His Humor_. In nothing are Chaucer's personality and his poetry more pleasing than in the rich humor which pervades them through and through. Sometimes, as in his treatment of the popular medieval beast-epic material in the Nun's Priest's Tale of the Fox and the Cock, the humor takes the form of boisterous farce; but much more often it is of the finer intellectual sort, the sort which a careless reader may not catch, but which touches with perfect sureness and charming lightness on all the incongruities of life, always, too, in kindly spirit. No foible is too trifling for Chaucer's quiet observation; while if he does not choose to denounce the hypocrisy of the Pardoner and the worldliness of the Monk, he has made their weaknesses sources of amusement (and indeed object-lessons as well) for all the coming generations. 3. _He is one of the greatest of all narrative poets_. Chaucer is an exquisite lyric poet, but only a few of his lyrics have come down to us, and his fame must always rest largely on his narratives. Here, first, he possesses unfailing fluency. It was with rapidity, evidently with ease, and with masterful certainty, that he poured out his long series of vivid and delightful tales. It is true that in his early, imitative, work he shares the medieval faults of wordiness, digression, and abstract symbolism; and, like most medieval writers, he chose rather to reshape material from the great contemporary store than to invent stories of his own. But these are really very minor matters. He has great variety, also, of narrative forms: elaborate allegories; love stories of many kinds; romances, both religious and secular; tales of chivalrous exploit, like that related by the Knight; humorous extravaganzas; and jocose renderings of coarse popular material--something, at least, in virtually every medieval type.
