The original ethical idea seems to have been simple enough; the sin of lack of faith in God, which mars an otherwise steadfast character. Feirefis shows, in a concrete form, the contrast sketched in the opening lines of Book I., and Parzival's final conflict with his parti-coloured brother signified the final victory over Doubt which rendered him worthy to win the Grail. The idea of working some such _motif_ into the story may very likely have arisen from a wish to supply a better and more adequate reason for Parzival's interview with the Hermit, an episode which, as the _Parzival_ shows, is capable of far finer treatment than it has received in any other version. (It must not be forgotten that Parzival's passionate outbreak and defiance of God is found nowhere else, and that the duty of trust in God and reliance upon Him in the hour of trouble has been distinctly part of his early teaching, and that there too the 'black and white' contrast has been insisted upon.) The idea thus first suggested, the circumstances of a residence in the East, where such a conflict between light and darkness was actually being carried on, determined the form into which it should be cast. It is extremely difficult to understand how _Wolfram_, if he only possessed the Perceval legend in an incomplete form, conceived the idea of supplementing it in this special manner; but if _Kiot_ be responsible for the first introduction of the religious idea, as he was of the Angevin, the problem becomes perfectly easy, his conception of the struggle in the soul of man was simply a reflection of the struggle as he saw it in the world. (It cannot be too strongly insisted upon, that no princes of the day were more strongly affected by the Crusading spirit, or more closely connected with the East than the Angevin princes; and that to assume on the part of one of their followers the familiarity with Crusading ideas which is here ascribed to 'Kiot' is to do little more than state a commonplace fact of history.) But that the idea of the poem has, in a measure, undergone a change, and that the _Parzival_ in its present shape owes much to the genius of the man who, probably attracted by the ethical turn Kiot had given to the story, took it into his own hands, and, remodelling it, sent it forth to the world a heritage for all generations, may readily be granted. No careful reader of the poem can fail to feel that the interpretation is a double one; that if there are passages which seem to treat of Faith and Doubt only as they affect the position of the soul towards God, there are others which as clearly treat of the same questions as affecting man's relation to his fellow-men; in which faith is interpreted in its widest sense as a loyal fulfilment of _all_ obligations, social as well as religious; and that all this is summed up and expressed in the inculcation of loyalty to the dictates of the knightly order in their highest form.
