This limitation may have a convenience and a value in the story, it may contribute to the effect. But it need not be forfeited, it is clear, if the first person is changed to the third. The author may use the man's field of vision and keep as faithfully within it as though the man were speaking for himself. In that case he retains this advantage and adds to it another, one that is likely to be very much greater. For now, while the point of view is still fixed in space, still assigned to the man in the book, it is free in _time_; there no longer stretches, between the narrator and the events of which he speaks, a certain tract of time, across which the past must appear in a more or less distant perspective. All the variety obtainable by a shifting relation to the story in time is thus in the author's hand; the safe serenity of a far retrospect, the promising or threatening urgency of the present, every gradation between the two, can be drawn into the whole effect of the book, and all of it without any change of the seeing eye. It is a liberty that may help the story indefinitely, raising this matter into strong relief, throwing that other back into vaguer shade. And next, still keeping mainly and ostensibly to the same point of view, the author has the chance of using a much greater latitude than he need appear to use. The seeing eye is with somebody in the book, but its vision is reinforced; the picture contains more, becomes richer and fuller, because it is the author's as well as his creature's, both at once. Nobody notices, but in fact there are now two brains behind that eye; and one of them is the author's, who adopts and shares the _position_ of his creature, and at the same time supplements his wit. If you analyse the picture that is now presented, you find that it is not all the work of the personage whose vision the author has adopted. There are touches in it that go beyond any sensation of his, and indicate that some one else is looking over his shoulder--seeing things from the same angle, but seeing more, bringing another mind to bear upon the scene. It is an easy and natural extension of the personage's power of observation. The impression of the scene may be deepened as much as need be; it is not confined to the scope of one mind, and yet there is no blurring of the focus by a double point of view. And thus what I have called the sound of the narrator's voice (it is impossible to avoid this mixture of metaphors) is less insistent in oblique narration, even while it seems to be following the very same argument that it would in direct, because another voice is speedily mixed and blended with it.
