You cannot have good matter with bad style. Examine the point more closely. A man wishes to convey a fine idea to you. He employs a form of words. That form of words is his style. Having read, you say: “Yes, this idea is fine.” The writer has therefore achieved his end. But in what imaginable circumstances can you say: “Yes, this idea is fine, but the style is not fine”? The sole medium of communication between you and the author has been the form of words. The fine idea has reached you. How? In the words, by the words. Hence the fineness must be in the words. You may say, superiorly: “He has expressed himself clumsily, but I can see what he means.” By what light? By something in the words, in the style. That something is fine. Moreover, if the style is clumsy, are you sure that you can see what he means? You cannot be quite sure. And at any rate, you cannot see distinctly. The “matter” is what actually reaches you, and it must necessarily be affected by the style.
Still further to comprehend what style is, let me ask you to think of a writer’s style exactly as you would think of the gestures and manners of an acquaintance. You know the man whose demeanour is “always calm,” but whose passions are strong. How do you know that his passions are strong? Because he “gives them away” by some small, but important, part of his demeanour, such as the twitching of a lip or the whitening of the knuckles caused by clenching the hand. In other words, his demeanour, fundamentally, is not calm. You know the man who is always “smoothly polite and agreeable,” but who affects you unpleasantly.
