What was the cause of this change? That is precisely the point on which, after all the gossip there has been, we are still ignorant. At times Coleridge’s opium excesses were great; but what led to those excesses must not be left out of account. From boyhood he had a tendency to low fever, betrayed by his constant appetite for bathing and swimming, which he indulged even when a physician had opposed it. In 1803, he went to Malta as secretary to the English Governor. His daughter suspects that the source of the evil was there, that for one of his constitution the climate of Malta was deadly. At all events, when he returned, the charm of those five wonderful years had failed at the source.

De Quincey said of him, ‘he wanted better bread than can be made with wheat.’ Lamb said of him that from boyhood he had ‘hungered for eternity’. Henceforth those are the two notes of his life. From this time we must look for no more true literary talent in him. His style becomes greyer and greyer, his thoughts outré, exaggerated, a kind of credulity or superstition exercised upon abstract words. Like Clifford, in Hawthorne’s beautiful romance—the born Epicurean, who by some strange wrong has passed the best of his days in a prison—he is the victim of a division of the will, often showing itself in trivial things: he could never choose on which side of the garden path he would walk. In 1803, he wrote a poem on ‘The Pains of Sleep’. That unrest increased. Mr. Gillman tells us ‘he had long been greatly afflicted with nightmare, and when residing with us was frequently aroused from this painful sleep by any one of the family who might hear him’.

That faintness and continual dissolution had its own consumptive refinements, and even brought, as to the ‘Beautiful Soul’ in Wilhelm Meister, a faint religious ecstasy—that ‘singing in the sails’ which is not of the breeze. Here, again, is a note of Coleridge’s:

‘In looking at objects of nature while I am thinking, as at yonder moon, dim-glimmering through the window-pane, I seem rather to be seeking, as it were asking, a symbolical language for something within me that already and for ever exists, than observing anything new. Even when that latter is the case, yet still I have always an obscure feeling, as if that new phenomenon were the dim awaking of a forgotten or hidden truth of my inner nature.’ Then, ‘while I was preparing the pen to write this remark, I lost the train of thought which had led me to it.’

What a distemper of the eye of the mind! What an almost bodily distemper there is in that!

Coleridge’s intellectual sorrows were many; but he had one singular intellectual happiness. With an inborn taste for transcendental philosophy he lived just at the time when that philosophy took an immense spring in Germany, and connected itself with a brilliant literary movement. He had the luck to light upon it in its freshness, and introduce it to his countrymen. What an opportunity for one reared on the colourless English philosophies, but who feels an irresistible attraction towards metaphysical synthesis! How rare are such occasions of intellectual contentment! This transcendental philosophy, chiefly as systematized by Schelling, Coleridge applies, with an eager, unwearied subtlety, to the questions of theology and art-criticism. It is in his theory of art-criticism that he comes nearest to true and important principles; that is the least fugitive part of his work. Let us take this first; here we shall most clearly apprehend his main principle.

What, then, is the essence of this criticism? On the whole it may be described as an attempt to reclaim the world of art as a world of fixed laws—to show that the creative activity of genius and the simplest act of thought are but higher and lower products of the laws of a universal logic. Criticism, feeling its own unsuccess in dealing with the greater works of art, has sometimes made too much of those dark and capricious suggestions of genius which even the intellect possessed by them is unable to track or recall. It has seemed due to their half-sacred character to look for no link between the process by which they were produced and the slighter processes of the mind. Coleridge assumes that the highest phases of thought must be more, not less, than the lower, subjects of law.

With this interest, in the Biographia Literaria, he refines Schelling’s ‘Philosophy of Nature’ into a theory of art. ‘Es giebt kein Plagiat in der Philosophie’ says Heine, alluding to the charge brought against Schelling of unacknowledged borrowing from Bruno, and certainly that which is common to Coleridge and Schelling is of far earlier origin than the Renaissance. Schellingism, the ‘Philosophy of Nature’, is indeed a constant tradition in the history of thought; it embodies a permanent type of the speculative temper. That mode of conceiving nature as a mirror or reflex of the intelligence of man may be traced up to the first beginnings of Greek speculation. There are two ways of envisaging those aspects of nature which appear to bear the impress of reason or intelligence. There is the deist’s way, which regards them merely as marks of design, which separates the informing mind from nature, as the mechanist from the machine; and there is the pantheistic way, which identifies the two, which regards nature itself as the living energy of an intelligence of the same kind as, but vaster than, the human. Greek philosophy, finding indications of mind everywhere, dwelling exclusively in its observations on that which is general or formal, on that which modern criticism regards as the modification of things by the mind of the observer, adopts the latter, or pantheistic way, through the influence of the previous mythological period. Mythology begins in the early necessities of language, of which it is a kind of accident. But at a later period its essence changes; it becomes what it was not at its birth, the servant of a genuine poetic interest, a kind of vivification of nature. Played upon by those accidents of language, the Greek mind becomes possessed by the conception of nature as living, thinking, almost speaking to the mind of man. This unfixed poetical prepossession, reduced to an abstract form, petrified into an idea, is the conception which gives a unity of aim to Greek philosophy. Step by step it works out the substance of the Hegelian formula: ‘Was ist, das ist vernünftig; was vernünftig ist, das ist’—‘Whatever is, is according to reason; whatever is according to reason, that is.’ A science of which that could be the formula is still but an intellectual aspiration; the formula of true science is different. Experience, which has gradually saddened the earth’s colour, stiffened its motions, withdrawn from it some blithe and debonair presence, has moderated our demands upon science. The positive method makes very little account of marks of intelligence in nature; in its wider view of phenomena it sees that those incidents are a minority, and may rank as happy coincidences; it absorbs them in the simpler conception of law. But the suspicion of a mind latent in nature, struggling for release and intercourse with the intellect of man through true ideas, has never ceased to haunt a certain class of minds. Started again and again in successive periods by enthusiasts on the antique pattern, in each case the thought has seemed paler and more evanescent amidst the growing consistency and sharpness of outline of other and more positive forms of knowledge. Still, wherever a speculative instinct has been united with extreme inwardness of temperament, as in Jakob Böhme, there the old Greek conception, like some seed floating in the air, has taken root and sprung up anew. Coleridge, thrust inward upon himself, driven from ‘life in thought and sensation’ to life in thought only, feels in that dark London school a thread of the Greek mind vibrating strangely in him. At fifteen he is discoursing on Plotinus, and has translated the hymns of Synesius. So in later years he reflects from Schelling the flitting tradition. He conceives a subtle co-ordination between the ideas of the mind and the laws of the natural world. Science is to be attained, not by observation, analysis, generalization, but by the evolution or recovery of those ideas from within, by a sort of ἀνάμνησις, every group of observed facts remaining an enigma until the appropriate idea is struck upon them from the mind of Newton or Cuvier, the genius in whom sympathy with the universal reason is entire. Next he supposes that this reason or intelligence in nature gradually becomes reflective—self-conscious. He fancies he can track through all the simpler orders of life fragments of an eloquent prophecy about the human mind. He regards the whole of nature as a development of higher forms out of the lower, through shade after shade of systematic change. The dim stir of chemical atoms towards the axes of a crystal form, the trance-like life of plants, the animal troubled by strange irritabilities, are stages which anticipate consciousness. All through that increasing stir of life this was forming itself; each stage in its unsatisfied susceptibilities seeming to be drawn out of its own limits by the more pronounced current of life on its confines, the ‘shadow of approaching humanity’ gradually deepening, the latent intelligence working to the surface. At this point the law of development does not lose itself in caprice; rather it becomes more constraining and incisive. From the lowest to the highest acts of intelligence, there is another range of refining shades. Gradually the mind concentrates itself, frees itself from the limits of the particular, the individual, attains a strange power of modifying and centralizing what it receives from without according to an inward ideal. At last, in imaginative genius, ideas become effective; the intelligence of nature, with all its elements connected and justified, is clearly reflected; and the interpretation of its latent purposes is fixed in works of art.

In this fanciful and bizarre attempt to rationalize art, to range it under the dominion of law, there is still a gap to be filled up. What is that common law of the mind, of which a work of art and the slighter acts of thought are alike products? Here Coleridge weaves in Kant’s fine-spun theory of the transformation of sense into perception. What every theory of perception has to explain is that associative power which gathers isolated sensible qualities into the objects of the world about us. Sense, without an associative power, would be only a threadlike stream of colours, sounds, odours—each struck upon one for a moment, and then withdrawn. The basis of this association may be represented as a material one, a kind of many-coloured ‘etching’ on the brain. Hartley has dexterously handled this hypothesis. The charm of his ‘theory of vibrations’ is the vivid image it presents to the fancy. How large an element in a speculative talent is the command of these happy images! Coleridge, by a finer effort of the same kind, a greater delicacy of fancy, detects all sorts of slips, transitions, breaks of continuity in Hartley’s glancing cobweb. Coleridge, with Kant, regards all association as effected by a power within, to which he gives a fanciful Greek name.[39] In an act of perception there is the matter which sense presents, colour, tone, feeling; but also a form or mould, such as space, unity, causation, suggested from within. In these forms we arrest and frame the many attributes of sense. It is like that simple chemical phenomenon where two colourless fluids uniting reflect a full colour. Neither matter nor form can be perceived asunder; they unite into the many-coloured image of life. This theory has not been able to bear a loyal induction. Even if it were true, how little it would tell us; how it attenuates fact! There, again, the charm is all in the clear image; the image of the artist combining a few elementary colours, curves, sounds into a new whole. Well, this power of association, of concentrating many elements of sense in an object of perception, is refined and deepened into the creative acts of imagination.

We of the modern ages have become so familiarized with the greater works of art that we are little sensitive of the act of creation in them; they do not impress us as a new presence in the world. Only sometimes in productions which realize immediately a profound emotion and enforce a change in taste, such as Werther or Emile, we are actual witnesses of the moulding of an unforeseen type by some new principle of association. By imagination, the distinction between which and fancy is so thrust upon his readers, Coleridge means a vigorous act of association, which, by simplifying and restraining their natural expression to an artificial order, refines and perfects the types of human passion. It represents the excitements of the human kind, but reflected in a new manner, ‘excitement itself imitating order.’ ‘Originally the offspring of passion,’ he somewhere says, ‘but now the adopted children of power.’ So far there is nothing new or distinctive; every one who can receive from a poem or picture a total impression will admit so much. What makes the view distinctive in Coleridge are the Schellingistic associations with which he colours it, that faint glamour of the philosophy of nature which was ever influencing his thoughts. That suggested the idea of a subtly winding parallel, a ‘rapport’ in every detail, between the human mind and the world without it, laws of nature being so many transformed ideas. Conversely, the ideas of the human mind would be only transformed laws. Genius would be in a literal sense an exquisitely purged sympathy with nature. Those associative conceptions of the imagination, those unforeseen types of passion, would come, not so much of the artifice and invention of the understanding, as from self-surrender to the suggestions of nature; they would be evolved by the stir of nature itself realizing the highest reach of its latent intelligence; they would have a kind of antecedent necessity to rise at some time to the surface of the human mind.
