Let us ask now what materials this story possesses, which have so recommended it to the genius of modern Europe for a high dramatic treatment; and for an answer to this question happily we have not far to seek. The moral significance of the legend lies on the surface of the popular chap-book; and the dramatic writer who should have omitted it altogether, would have proved himself unworthy of the noble function which he exercises. 'Tis the world-old story of the pride of knowledge, and the impatience of limitation with which that knowledge is often accompanied. "/Eritis sicut Deus, scientes bonum et malum/." "Ye shall be as gods, knowing good and evil." The desire to be as God, looking into the soul of things, and commanding the mystical machinery of the universe, is the rank outblossoming of an unchastened intellectual ambition, leading naturally to discontent with the common human limits of the knowable, and to a morbid intermeddling with supernatural powers and forces, in order to lift the lofty speculator, out of the vulgar sphere of confined humanity. This kicking against the bars of finite knowledge is of course rebellion against the constitution of things, disownment of the divine authority which imposed these limitations, and alliance with the Evil Spirit, whom popular belief acknowledges as the incarnation of that spirit of impatience, pride, and presumption, out of which this rebellion springs. Here we have the real motive which gives moral dignity and human interest to the legend of Faust. The compact of the Wittenberg doctor with Mephistopheles is only a striking instance of what is constantly taking place in the thinking world before us, especially in these days of curious microscopic prying into the seeds of things, and pretentious parading of all sorts of dogmatic and negative philosophies, ambitiously engaged in the insane attempt to explain the existence of a reasonable world, independent of a reasonable cause. "Knowledge puffeth up, but charity edifieth." It is the greed of knowledge, where knowledge is not possible, and the lack of love and reverence, the indispensable conditions of moral sanity, that in ages of dreamy speculation lead to the practice of magic and necromancy, and in days of nice scientific measurement, to a hollow and heartless atheism, clothing itself in the philosopher's mantle and accepted as wisdom by the unthinking. This aspect of the Faust legend, accordingly, did not escape the notice of Marlow, who has set it forth prominently, if not profoundly, in the opening scene of his drama; a scene which bears, indeed, a striking likeness to the opening scene in Goethe's poem, in the fashion that a rough-hewn Highland hut is the same sort of thing as a neat English cottage, only in a more rude and unscientific style. A secondary element contained in the Faust legend arises out of the reaction which, in certain natures, is apt to plunge disappointed intellectual ambition into a course of sensual indulgence.
