There are few things more perplexing than the attempt to choose from the all but innumerable books of our own day those which are to be considered as genuine. If we are able to keep vividly in mind what qualities make a thing literature, it is possible to have some not inadequate idea of what contemporary writings most completely fulfill the given conditions. We are able to speak with assurance of the work of a Tennyson or a Browning; and to feel that we have witnessed the birth of classics of the future. Beside these, however, stand the enormous multitude of books which are widely read, much talked about, and voluminously advertised; books which we cannot openly dispraise without the risk of being sneered at as captious or condemned as conceited. There are the poems which publishers inform the public in column-long advertisements, bristling with the testimonials of men and women who make writing their business, are the finest productions since Shakespeare; there are the novels which prove themselves to be works of genius by selling by the hundreds of thousands of copies and very likely being given to the purchasers of six bars of some patent soap; there are the thin and persecuted looking volumes of "prose poems" or rhyming prose which are looked upon by small bands of devoted followers as the morsel of leaven which is to leaven the whole lump; there are, in short, all those perplexing writings which have merit of some kind and in some degree, yet to decide the genuine and lasting merit of which might tax the wisdom and the patience of a Solomon of Solomons. I have already spoken of the effect which temporary qualities are sure to have in determining the success of an author. The history of books is full of instances of works which have in their brief day filled the reading world with noisy admiration, but which have in the end been found destitute of enduring merit. While transient fame is at its height, while enthusiastically injudicious admirers are praising and judiciously enthusiastic publishers are reëchoing their plaudits, it is a well-trained mind that is able to form a sound and rational judgment, and to distinguish between the ephemeral and the abiding. The only hope lies in a careful and discriminating application of standards deduced from the classics. He who desires to judge the books of to-day must depend upon comparison with the books of yesterday. He must be able to feel toward the literature of the past as if it were of the present, and toward that of the present as if it were of the past.
