From "A Humble Remonstrance" (a response to Henry James's "The Art of Fiction") in R. L. Stevenson on Fiction:
"... No art — to use the daring phrase of Mr. James — can successfully “compete with life”; and the art that seeks to do so is condemned to perish Montibus Aviis. Life goes before us, infinite in complication; attended by the most various and surprising meteors; appealing at once to the eye, to the ear, to the mind — the seat of wonder, to the touch — so thrillingly delicate, and to the belly — so imperious when starved. It combines and employs in its manifestation the method and material, not of one art only, but of all the arts, Music is but an arbitrary trifling with a few of life’s majestic chords; painting is but a shadow of its pageantry of light and colour; literature does but drily indicate that wealth of incident, of moral obligation, of virtue, vice, action, rapture and agony, with which it teems. To “compete with life,” whose sun we cannot look upon, whose passions and diseases waste and slay us — to compete with the flavour of wine, the beauty of the dawn, the scorching of fire, the bitterness of death and separation — here is, indeed, a projected escalade of heaven; here are, indeed, labours for a Hercules in a dress coat, armed with a pen and a dictionary to depict the passions, armed with a tube of superior flake-white to paint the portrait of the insufferable sun. No art is true in this sense: none can “compete with life”: not even history, built indeed of indisputable facts, but these facts robbed of their vivacity and sting; so that even when we read of the sack of a city or the fall of an empire, we are surprised, and justly commend the author’s talent, if our pulse be quickened. And mark, for a last differentia, that this quickening of the pulse is, in almost every case, purely agreeable; that these phantom reproductions of experience, even at their most acute, convey decided pleasure; while experience itself, in the cockpit of life, can torture and slay.
What, then, is the object, what the method, of an art, and what the source of its power? The whole secret is that no art does “compete with life.” Man’s one method, whether he reasons or creates, is to half-shut his eyes against the dazzle and confusion of reality. The arts, like arithmetic and geometry, turn away their eyes from the gross, coloured and mobile nature at our feet, and regard instead a certain figmentary abstraction. Geometry will tell us of a circle, a thing never seen in nature; asked about a green circle or an iron circle, it lays its hand upon its mouth. So with the arts. Painting, ruefully comparing sunshine and flake-white, gives up truth of colour, as it had already given up relief and movement; and instead of vying with nature, arranges a scheme of harmonious tints. Literature, above all in its most typical mood, the mood of narrative, similarly flees the direct challenge and pursues instead an independent and creative aim. So far as it imitates at all, it imitates not life but speech: not the facts of human destiny, but the emphasis and the suppressions with which the human actor tells of them. The real art that dealt with life directly was that of the first men who told their stories round the savage camp-fire. Our art is occupied, and bound to be occupied, not so much in making stories true as in making them typical; not so much in capturing the lineaments of each fact, as in marshalling all of them towards a common end. For the welter of impressions, all forcible but all discreet, which life presents, it substitutes a certain artificial series of impressions, all indeed most feebly represented, but all aiming at the same effect, all eloquent of the same idea, all chiming together like consonant notes in music or like the graduated tints in a good picture. From all its chapters, from all its pages, from all its sentences, the well-written novel echoes and re-echoes its one creative and controlling thought; to this must every incident and character contribute; the style must have been pitched in unison with this; and if there is anywhere a word that looks another way, the book would be stronger, clearer, and (I had almost said) fuller without it. Life is monstrous, infinite, illogical, abrupt and poignant; a work of art, in comparison, is neat, finite, self-contained, rational, flowing and emasculate. Life imposes by brute energy, like inarticulate thunder; art catches the ear, among the far louder noises of experience, like an air artificially made by a discreet musician. A proposition of geometry does not compete with life; and a proposition of geometry is a fair and luminous parallel for a work of art. Both are reasonable, both untrue to the crude fact; both inhere in nature, neither represents it. The novel, which is a work of art, exists, not by its resemblances to life, which are forced and material, as a shoe must still consist of leather, but by its immeasurable difference from life, which is designed and significant, and is both the method and the meaning of the work..."
