Vaughan and Wordsworth stand pre-eminent among our English poets in being almost exclusively occupied with one theme, the mystical interpretation of nature. Both poets are of a meditative, brooding cast of mind; but whereas Wordsworth arrives at his philosophy entirely through personal experience and sensation, Vaughan is more of a mystical philosopher, deeply read in Plato and the mediæval alchemists. The constant comparison of natural with spiritual processes is, on the whole, the most marked feature of Vaughan's poetry. If man will but attend, he seems to say to us, everything will discourse to him of the spirit. He broods on the silk-worm's change into the butterfly (Resurrection and Immortality); he ponders over the mystery of the continuity of life as seen in the plant, dying down and entirely disappearing in winter, and shooting up anew in the spring (The Hidden Flower); or, while wandering by his beloved river Usk, he meditates near the deep pool of a waterfall on its mystical significance as it seems to linger beneath the banks and then to shoot onward in swifter course, and he sees in it an image of life beyond the grave. The seed growing secretly in the earth suggests to him the growth of the soul in the darkness of physical matter; and in Affliction he points out that all nature is governed by a law of periodicity and contrast, night and day, sunshine and shower; and as the beauty of colour can only exist by contrast, so are pain, sickness, and trouble needful for the development of man. These poems are sufficient to illustrate the temper of Vaughan's mind, his keen, reverent observation of nature in all her moods, and his intense interest in the minutest happenings, because they are all manifestations of the one mighty law.

Vaughan appears to have had a more definite belief in pre-existence than Wordsworth, for he refers to it more than once; and The Retreate, which is probably the best known of all his poems and must have furnished some suggestion for the Immortality Ode, is based upon it. Vaughan has occasionally an almost perfect felicity of mystical expression, a power he shares with Donne, Keats, Rossetti, and Wordsworth. His ideas then produce their effect through the medium of art, directly on the feelings. The poem called Quickness is perhaps the best example of this peculiar quality, which cannot be analysed but must simply be felt; or The World, with its magnificent symbol in the opening lines:—

I saw Eternity the other night,
Like a great Ring of pure and endless light,
All calm, as it was bright;
And round beneath it, Time, in hours, days, years,
Driv'n by the spheres,
Like a vast shadow mov'd.[21]

Mysticism is the most salient feature of Wordsworth's poetry, for he was one who saw, whose inward eye was focussed to visions scarce dreamt of by men. It is because of the strangeness and unfamiliarity of his vision that he is a difficult poet to understand, and the key to the understanding of him is a mystic one. People talk of the difficulty of Browning, but he is easy reading compared with a great deal of Wordsworth. It is just the apparent simplicity of Wordsworth's thought which is so misleading. A statement about him of the following kind would be fairly generally accepted as the truth. Wordsworth was a simple-minded poet with a passion for nature, he found great joy and consolation in the contemplation of the beauty of hills and dales and clouds and flowers, and urged others to find this too; he lived, and recommended others to live a quiet retired unexciting kind of life, and he preached a doctrine of simplicity and austerity. Now, except that Wordsworth had a passion for Nature, there is not a single true statement here. Wordsworth was not only a poet, he was also a seer, a mystic and a practical psychologist with an amazingly subtle mind, and an unusual capacity for feeling; he lived a life of excitement and passion, and he preached a doctrine of magnificence and glory. It was not the beauty of Nature which brought him joy and peace, but the life in Nature. He himself had caught a vision of that life, he knew it and felt it, and it transformed the whole of existence for him. He believed that every man could attain this vision which he so fully possessed, and his whole life's work took the form of a minute and careful analysis of the processes of feeling in his own nature, which he left as a guide for those who would tread the same path. It would be correct to say that the whole of his poetry is a series of notes and investigations devoted to the practical and detailed explanation of how he considered this state of vision might be reached. He disdained no experience—however trivial, apparently—the working of the mind of a peasant child or an idiot boy, the effect produced on his own emotions by a flower, a glowworm, a bird's note, a girl's song; he passed by nothing which might help to throw light on this problem. The experience which Wordsworth was so anxious others should share was the following. He found that when his mind was freed from pre-occupation with disturbing objects, petty cares, "little enmities and low desires," that he could then reach a condition of equilibrium, which he describes as a "wise passiveness," or a "happy stillness of the mind." He believed this condition could be deliberately induced by a kind of relaxation of the will, and by a stilling of the busy intellect and striving desires. It is a purifying process, an emptying out of all that is worrying, self-assertive, and self-seeking. If we can habitually train ourselves and attune our minds to this condition, we may at any moment come across something which will arouse our emotions, and it is then, when our emotions—thus purified—are excited to the point of passion, that our vision becomes sufficiently clear to enable us to gain actual experience of the "central peace subsisting for ever at the heart of endless agitation." Once seen, this vision changes for us the whole of life; it reveals unity in what to our every-day sight appears to be diversity, harmony where ordinarily we hear but discord, and joy, overmastering joy, instead of sorrow.

It is a kind of illumination, whereby in a lightning flash we see that the world is quite different from what it ordinarily appears to be, and when it is over—for the experience is but momentary—it is impossible to describe the vision in precise terms, but the effect of it is such as to inspire and guide the whole subsequent life of the seer. Wordsworth several times depicts this "bliss ineffable" when "all his thought were steeped in feeling." The well-known passage in Tintern Abbey already quoted (p. 7) is one of the finest analysis of it left us by any of the seers, and it closely resembles the accounts given by Plotinus and Boehme of similar experiences.

To Wordsworth this vision came through Nature, and for this reason. He believed that all we see round us is alive, beating with the same life which pulsates in us. It is, he says,—

my faith that every flower
Enjoys the air it breathes.

and that if we will but listen and look, we will hear and see and feel this central life. This is the pith of the message we find repeated again and again in various forms throughout Wordsworth's poetry, and perhaps best summed up at the end of the fourth book of the Excursion, a book which should be closely studied by any one who would explore the secret of the poet's outlook upon life. He tells us in the Prelude (Book iii.) that even in boyhood it was by this feeling he "mounted to community with highest truth"—

To every natural form, rock, fruits, or flower,
Even the loose stones that cover the highway,
I gave a moral life: I saw them feel,
Or linked them to some feeling: the great mass
Lay bedded in a quickening soul, and all
That I beheld respired with inward meaning.

Wordsworth, in short, was haunted by the belief that the secret of the universe is written clearly all round us, could we but train and purify our mind and emotions so as to behold it. He believed that we are in something the same attitude towards Nature as an illiterate untrained person might be in the presence of a book containing the philosophy of Hegel. To the educated trained thinker, who by long and arduous discipline has developed his mental powers, that book contains the revelation of the thought of a great mind; whereas to the uneducated person it is merely a bundle of paper with words printed on it. He can handle it, touch it, see it, he can read the words, he can even understand many of them separately, but the essence of the book and its meaning remains closed to him until he can effect some alteration in himself which will enable him to understand it.
