"There lives more faith in honest doubt
Believe me than in half the creeds."
said Tennyson; "honest doubt," hugged with all the certainty of a revelation, is the creed of most of his philosophical poetry, and what is more to the point was the creed of the masses that were beginning to think for themselves, to whose awakening interest his work so strongly appealed. There were no doubt, literary side-currents. Disraeli survived to show that there were still young men who thought Byronically. Rossetti and his school held themselves proudly aloof from the rationalistic and scientific tendencies of the time, and found in the Middle ages, better understood than they had been either by Coleridge or Scott, a refuge from a time of factories and fact. The Oxford movement ministered to the same tendencies in religion and philosophy; but it is the scientific spirit, and all that the scientific spirit implied, its certain doubt, its care for minuteness, and truth of observation, its growing interest in social processes, and the conditions under which life is lived, that is the central fact in Victorian literature.
Tennyson represents more fully than any other poet this essential spirit of the age. If it be true, as has been often asserted, that the spirit of an age is to be found best in the work of lesser men, his complete identity with the thought of his time is in itself evidence of his inferiority to his contemporary, Browning. Comparison between the two men seem inevitable; they were made by readers when In Memoriam and Men and Women came hot from the press, and they have been made ever since. There could, of course, scarcely be two men more dissimilar, Tennyson elaborating and decorating the obvious; Browning delving into the esoteric and the obscure, and bringing up strange and unfamiliar finds; Tennyson in faultless verse registering current newly accepted ways of thought; Browning in advance thinking afresh for himself, occupied ceaselessly in the arduous labour of creating an audience fit to judge him. The age justified the accuracy with which Tennyson mirrored it, by accepting him and rejecting Browning. It is this very accuracy that almost forces us at this time to minimise and dispraise Tennyson's work. We have passed from Victorian certainties, and so he is apt when he writes in the mood of Locksley Hall and the rest, to appear to us a little shallow, a little empty, and a little pretentious.
His earlier poetry, before he took upon himself the burden of the age, is his best work, and it bears strongly marked upon it the influence of Keats. Such a poem for instance as Oenone shows an extraordinarily fine sense of language and melody, and the capacity caught from Keats of conveying a rich and highly coloured pictorial effect. No other poet, save Keats, has had a sense of colour so highly developed as Tennyson's. From his boyhood he was an exceedingly close and sympathetic observer of the outward forms of nature, and he makes a splendid use of what his eyes had taught him in these earlier poems. Later his interest in insects and birds and flowers outran the legitimate opportunity he possessed of using it in poetry. It was his habit, his son tells us, to keep notebooks of things he had observed in his garden or in his walks, and to work them up afterwards into similes for the Princess and the Idylls of the King. Read in the books written by admirers, in which they have been studied and collected (there are several of them) these similes are pleasing enough; in the text where they stand they are apt to have the air of impertinences, beautiful and extravagant impertinences no doubt, but alien to their setting. In one of the Idylls of the King the fall of a drunken knight from his horse is compared to the fall of a jutting edge of cliff and with it a lance-like fir-tree, which Tennyson had observed near his home, and one cannot resist the feeling that the comparison is a thought too great for the thing it was meant to illustrate. So, too, in the Princess when he describes a handwriting,
"In such a hand as when a field of corn
Bows all its ears before the roaring East."
he is using up a sight noted in his walks and transmuted into poetry on a trivial and frivolous occasion. You do not feel, in fact, that the handwriting visualized spontaneously called up the comparison; you are as good as certain that the simile existed waiting for use before the handwriting was thought of.
The accuracy of his observation of nature, his love of birds and larvae is matched by the carefulness with which he embodies, as soon as ever they were made, the discoveries of natural and physical science. Nowadays, possibly because these things have become commonplace to us, we may find him a little school-boy-like in his pride of knowledge. He knows that
"This world was once a fluid haze of light,
Till toward the centre set the starry tides
And eddied wild suns that wheeling cast
The planets."
just as he knows what the catkins on the willows are like, or the names of the butterflies: but he is capable, on occasion of "dragging it in," as in
"The nebulous star we call the sun,
If that hypothesis of theirs be sound."
