Even in the intercourse of everyday life, faith is a necessity. Now, had the easy-going Christian paused at this stage of the discussion, with line 82, his argument would have had the weight which attaches to an elaboration of the same theory given by Browning elsewhere--in _An Epistle of Karshish_. But even he, upon whom these considerations are forced for what one may well believe to be the first time, finds that any individual proposition requires constant modification, that a doubt will "peep unexpectedly." Thus, though faith, with its attendant uncertainty, may well obtain in the relations between man and man, yet, between the Creator and his creation, is it not possible that more clearly defined regulations shall subsist? (3) The thinker who is anxious to rightly adjust his own position in the world of faith interposes before the argument has passed to its final stage, and points to the conditions prevailing in the world of lower animal life where the entire creation "travails and groans"--reverting again to the assurance which, as the conclusion of the poem is to show, had been indelibly stamped upon his mind by the experience of the Vision--the assurance already referred to in Sections I and II, that could these conditions be changed, then, too, would be altered the character of human life, its purpose--as Browning ever regards it--would be annulled. This is not the place to discuss the question of the probationary character of life and its educative purpose; it is sufficient to recognize that in Nature is discoverable no definite and final answer to the questionings of doubt. Hence, with Section VI, the second speaker shifts his ground; and admitting that this suggested "scientific faith," is impracticable, declares himself none the more prepared, therefore, to yield such faith as may yet be possible to him. All he would ask is that the greater probability may rest upon the side of that creed which he professes. His belief, such as it is, affords him satisfaction, and will continue, so he holds, sufficient for his needs until its "curtain is furled away by death." And he would at once meet the arguments which he sees his companion prepared to advance in favour of asceticism. To give up the world for Eternity is surely an act sufficiently easy of accomplishment, since the renunciation is daily effected for causes of small moment. Whilst the would-be Christian shrinks at prospect of the hardships involved in self-denial, his worldly neighbour is adopting that self-same life of abstention that he may attain an object no more important than that of acquiring a record collection of beetles or of snuff-boxes. In short, in the speaker's own words, by subduing the demands of the flesh, he would be Doing that alone, To gain a palm-branch and a throne, Which fifty people undertake To do, and gladly, for the sake Of giving a Semitic guess, Or playing pawns at blindfold chess. (ll. 165-170.)
