The specimens of natural history are perfect after their kind; the main question with them is, to which kind or species does a given specimen belong? But the poem or the history or the novel is not always perfect after its kind. Their kind is usually obvious at a glance, but their merits or demerits, their relation to the best that has been thought and done in the world, are not so obvious. Hence we praise or blame according as they come up to or fall short of their own ideal. The critic is not so much a botanist naming a new flower, as he is a brother gardener criticising your horticulture, or a brother lawyer criticising your brief. We are all critics in this sense one way or another every day of our lives; we try to get at the real value of whatever is offered us, whether it be lands, houses, goods, friends, stocks, bonds, news, pictures, or books; we criticise the men we deal with and employ in order to find out whom to trust; we must have our wits about us when we go to market or go shopping. The critical habit—sifting, testing, comparing, to get at the true value of things—goes with us through life, or else we come often to grief. The finer the product, or the higher the purpose it serves, the more careful is our investigation.

When we come to literature and art our worldly practical wisdom does not carry very far. It is not now a question of fact or of material values, but of ideal and æsthetic values; it is a question of truth to nature and to life, and of the largest, most vital truth. The mass of readers have little power of divining the good from the bad, the true from the false, in this field. Not the first best, but the second or third best will draw the multitude.

The literary value of a work is more intangible and elusive, harder to define and bring out, than its scientific or moral or other values. It resides in a certain vitality and genuineness of expression; we have a sense of having come face to face with something real and alive in the man, and not, as is so often the case; with something assumed or put on. There is always an original inherent quality and flavor, as in natural products. The language is not the mere garment of the thought, it is the very texture and substance. In all true literature something more than mind and erudition speak,—a man speaks; a vital personality is imminent,—a Charles Lamb, a Wordsworth, a Carlyle, a Huxley, an Emerson, a Thoreau, a Lowell,—all distinct types of intelligence speaking through character.

Self-expression within certain limits is as important in criticism as in any other form of literature.

The French critic Ferdinand Brunetière says that the truly personal way of seeing and feeling, which is a merit of the poet and the novelist, is a fault in the critic, because the critical function is mainly a judicial one.

In every man there is the common humanity, a measure of the pure reason which he shares with all; then there are the race traits, the family traits, the bias of his times, the bent given by his training and surroundings, and his own special stamp and make-up,—what we call his idiosyncrasy. All these things will play a part in his view of any matter. His success as a critic is when his humanity, his pure intelligence, furnishes the light which is only colored or refracted by its passage through these elements. But colored and refracted it will be, and it is this coloring and refraction or stamp of the personal equation that gives value and charm to the man’s work as literature. Reduce criticism to a science, or eliminate the element of impressionism, and the result is no longer literature. The reason may be convinced, but the emotions are untouched.

The one thing that distinguishes all modern literatures from the works of the ancient or classic period is their more permanent subjectivity, and the piercing lyrical note in them.

Self-expression has been the aim of the modern artist in a much fuller sense than it was with the artists of the pagan world. Our religion is a personal and subjective religion,—the kingdom of heaven is within. Christianity turned the thoughts of men upon themselves. Self-examination, self-criticism began. Man became conscious of himself, of his sins, and of his shortcomings, and learned to be more interested in the elements of his own character.

There is probably no greater delusion than that under which the critic labors when he thinks he is trying the new work by the standard of the best that has been thought and achieved in the world. He is trying it by his own conception of that standard; so much of it as is vital in his own mind he can apply, and no more. His own individual taste and judgment are, after all, his tests. The standard of the best is not some rule of thumb or of yardstick that every one can apply; only the best can apply the best.

Impressionism, therefore, is at the bottom of all criticism, in whatever field. The impression which the work makes upon your intelligence, your taste, your judgment, is all that you can finally give.
