From early manhood to extreme old age 'Faust' was with Goethe, receiving now and again, in Frankfort, in Weimar, in Rome, some[Pg 6391] new accession. We can distinguish the strata or formations of youth, of manhood, and of the closing years. We recognize by their diversities of style those parts which were written when creation was swift and almost involuntary, a passion and a joy, and those parts through which Goethe labored at an old man's pace, accomplishing to-day a hand's-breadth, to-morrow perhaps less, and binding blank pages into his manuscript, that the sight of the gaps might irritate him to produce. What unity can such a work possess, except that which comes from the fact that it all proceeded from a single mind, and that some main threads of thought—for it would be rash to speak of a ground idea—run through the several parts and bind them together? 'Faust' has not the unity of a lake whose circuit the eye can contemplate, a crystal set among the hills. Its unity is that of a river, rising far away in mountain solitudes, winding below many a mirrored cliff, passing the habitations of men, temple and mart, fields of rural toil and fields of war, reaching it may be dull levels, and forgetting the bright speed it had, until at last the dash of waves is heard, and its course is accomplished; but from first to last one stream, proceeding from a single source. Tourists may pick out a picturesque fragment of its wanderings, and this is well; but perhaps it is better to find the poetry of its entire career, from its cloudy cradle to the flats where it loses itself in the ocean.
