And since these writers, who may, in the slang of the hour, be called "impressionists" in literature, follow their own bad taste in the manufacture of dainty phrases, devoid of all nerve, and generally with some quite commonplace meaning, it is all the more necessary to discriminate carefully between artifice and art. But although they may learn something from Schopenhauer's advice, it is not chiefly to them that it is offered. It is to that great mass of writers, whose business is to fill the columns of the newspapers and the pages of the review, and to produce the ton of novels that appear every year. Now that almost everyone who can hold a pen aspires to be called an author, it is well to emphasize the fact that literature is an art in some respects more important than any other. The problem of this art is the discovery of those qualities of style and treatment which entitled any work to be called good literature. It will be safe to warn the reader at the very outset that, if he wishes to avoid being led astray, he should in his search for these qualities turn to books that have stood the test of time. For such an amount of hasty writing is done in these days that it is really difficult for anyone who reads much of it to avoid contracting its faults, and thus gradually coming to terms of dangerous familiarity with bad methods. This advice will be especially needful if things that have little or no claim to be called literature at all--the newspapers, the monthly magazine, and the last new tale of intrigue or adventure--fill a large measure, if not the whole, of the time given to reading. Nor are those who are sincerely anxious to have the best thought in the best language quite free from danger if they give too much attention to the contemporary authors, even though these seem to think and write excellently. For one generation alone is incompetent to decide upon the merits of any author whatever; and as literature, like all art, is a thing of human invention, so it can be pronounced good only if it obtains lasting admiration, by establishing a permanent appeal to mankind's deepest feeling for truth and beauty. It is in this sense that Schopenhauer is perfectly right in holding that neglect of the ancient classics, which are the best of all models in the art of writing, will infallibly lead to a degeneration of literature. And the method of discovering the best qualities of style, and of forming a theory of writing, is not to follow some trick or mannerism that happens to please for the moment, but to study the way in which great authors have done their best work. It will be said that Schopenhauer tells us nothing we did not know before. Perhaps so; as he himself says, the best things are seldom new. But he puts the old truths in a fresh and forcible way; and no one who knows anything of good literature will deny that these truths are just now of very fit application.
