Against fashion

"...'for art's sake' alone I would not face the toil of writing a single sentence. I know that there are men who, having nothing to say and nothing to write, are nevertheless so in love with oratory and with literature that they delight in repeating as much as they can understand of what others have said or written aforetime. I know that the leisurely tricks which their want of conviction leaves them free to play with the diluted and misapprehended message supply them with a pleasant parlor game which they call style. I can pity their dotage and even sympathize with their fancy. But a true original style is never achieved for its own sake: a man may pay from a shilling to a guinea, according to his means, to see, hear, or read another man's act of genius; but he will not pay with his whole life and soul to become a mere virtuoso in literature, exhibiting an accomplishment which will not even make money for him, like fiddle playing. Effectiveness of assertion is the Alpha and Omega of style. He who has nothing to assert has no style and can have none: he who has something to assert will go as far in power of style as its momentousness and his conviction will carry him....
...All this academic art is far worse than the trade in sham antique furniture; for the man who sells me an oaken chest which he swears was made in the XIII century, though as a matter of fact he made it himself only yesterday, at least does not pretend that there are any modern ideas in it; whereas your academic copier of fossils offer them to you as the latest outpouring of the human spirit, and, worst of all, kidnaps young people as pupils and persuades them that his limitations are rules, his observances dexterities, his timidities good taste, and his emptinesses purities. And when he declares that art should not be didactic, all the people who have nothing to teach and all the people who don't want to learn agree with him emphatically."
Bernard Shaw, Man and Superman
