The conjurer juggles with two oranges, and our pleasure in beholding him springs from this, that neither is for an instant overlooked or sacrificed. So with the writer. His pattern, which is to please the supersensual ear, is yet addressed, throughout and first of all, to the demands of logic. Whatever be the obscurities, whatever the intricacies of the argument, the neatness of the fabric must not suffer, or the artist has been proved unequal to his design. And, on the other hand, no form of words must be selected, no knot must be tied among the phrases, unless knot and word be precisely what is wanted to forward and illuminate the argument; for to fail in this is to swindle in the game. The genius of prose rejects the cheville no less emphatically than the laws of verse; and the cheville, I should perhaps explain to some of my readers, is any meaningless or very watered phrase employed to strike a balance in the sound. Pattern and argument live in each other; and it is by the brevity, clearness, charm, or emphasis of the second, that we judge the strength and fitness of the first.
Style is synthetic; and the artist, seeking, so to speak, a peg to plait about, takes up at once two or more elements or two or more views of the subject in hand; combines, implicates, and contrasts them; and while, in one sense, he was merely seeking an occasion for the necessary knot, he will be found, in the other, to have greatly enriched the meaning, or to have transacted the work of two sentences in the space of one.
