When a significance, which as such co-ordinates a homogeneous complexus of relations, is apprehended exclusively as significance, yet does not receive the form strictly adequate to this content, but is merely invested with the external ornamentation of art, then we have before us the didactic poem. The didactic poem does not figure among the genuine types of art. For in it we find on the one hand a content already completely elaborated under a mode that is thereby necessarily prosaic, while on the other we have the artistic form, which is merely tacked to it in an external way, for this very reason that it had already been accepted by the mind in a form stamped with prose throughout, and is merely exhibited to our common sense or reflective faculties as instruction under this prosaic aspect, that is to say, with an exclusive reference to the significance embodied in its abstract and general terms. Consequently art, in this its external relation to a content so essentially foreign to its real informing process, can only recognize in the didactic poem its external aspects, such as metre, exalted language, episodic matter, images, similes, ebullitions of sentiment, points of acceleration and transition in the march of ideas, aspects in short which do not give us the heart of the content as such, but rather surround it as an incidental accretion, with the object of alleviating and making more enjoyable the serious and dry tone of the didactic material by means of their more inspiriting atmosphere. That which is intrinsically, in the fundamental conception of it, relegated to prose, cannot receive the poet's mintage, though it may be the peg on which he may hang his mantle[120]. Just as we find, for example, that the art of gardening is in great measure a purely external rearrangement of what is already presented us by Nature, but not necessarily of that which is itself a truly lovely locality; or as the art of building ameliorates by its ornament and external decoration a locality which has been expressly devoted to prosaic purposes and affairs.
In this way Greek Philosophy made a start under the mode of the didactic poem. We may even adduce Hesiod as an example, albeit a prosaic treatment of this kind in its strict sense is only fully assured when the understanding is undisputed master of the subject with its train of reflections, consequences, and classifications, and instructs us from this standpoint alone in as pleasing and elegant a way as it can. Lucretius, too, in his relations to the philosophy of Epicurus, and Vergil, with the information he supplies on agriculture, are in part examples of the same type. Despite all their artistic adroitness they are unable to give their versification the genuine spontaneity of the artistic form. In Germany the didactic poem is new out of fashion; in France Delille, in addition to his previous efforts entitled "Les jardins, ou l'art d'embellir les paysages," and his "Homme des champs," has presented his compatriots with a further example of the didactic poem, in which he has treated physical science as compendiously through its forms of magnetism, electricity and the rest.
2. DESCRIPTIVE POETRY
The second type which we have to examine stands out in direct contrast to the previous one. The point of departure here is not from a significance already present before the mind in an independent form of its own, but from external objects simply such as natural localities, buildings, seasons of the year or periods of time, and the modes under which they are presented to sense. But as we found in the didactic poem the content persisted in formless generality so far as its essential character was concerned, so here, if in a converse manner, the external material is independently set forth in the singularity which pertains to it simply as phenomenon without being drawn within the circle of the significances apparent to mind; and it is this particularity which is depicted and described in its external aspect precisely as it appears to the matter-of-fact consciousness. Such a sensuous content has no relation to true art whatever, except under the one feature, namely, that of its external existence; and this can only claim art's recognition in so far as it represents the natural basis of spiritual life and individuality, its actions and events, the facts, that is to say, which constitute an environing world; as merely external form separated by itself from all that pertains to such life it has no such claim.
3. RELATION OF BOTH ASPECTS
On grounds deducible from the above, neither the instructive nor the descriptive type is secured in the exclusive one-sidedness which would obliterate every vestige of art, and we find in the one case that the external reality is brought into appreciable relation with that which is seized by mind as significance, just as conversely in the other the abstract universal is related to its concrete mode of appearance.
(a) We have already explained how this is so in the case of the didactic poem. Without depicting external conditions and particular phenomena, without the episodical narration of mythological and other illustrations we shall rarely find a genuine example of it. By means, however, of a parallel series of this character in which the universal for mind is thus laid alongside of the particular object of sense we have merely a quite collateral relation set up instead of a union carried out in every detail, a parallelogism, moreover, which does not affect the entire content and its all-embracing artistic form, but merely isolated aspects and traits.
(b) Such a modicum of true relation is particularly conspicuous in the case of descriptive poetry, in so far as its delineations are accompanied with such emotions as the sight of natural landscape, the course of the days and seasons, a wooded hill, a lake, a babbling brook, a church, a picturesquely situated village and the poor man's peaceful cottage are likely to arouse. We find consequently in descriptive poetry much as we do in the didactic poem episodes which, although merely accessory, animate us, in particular through the reflection of affecting emotions, such as a tender melancholy or little touches of occasional experience taken from the more homely levels of life. Such an association of spiritual feeling with the external facts of Nature can still only too easily in this type of poetry remain wholly external in its presentation. For the natural or local condition is here assumed to be something which quite independently confronts us. Man no doubt draws near to it; under its influence he entertains this or that feeling, but there is nothing which essentially unites moonlight, forests, valleys, landscape, and so on, with the emotions of the soul they excite. I am not here either the interpreter or the animating focus of Nature, but feel, as each happens to confront me, a wholly indefinite kind of harmonious reciprocity establish itself between the objects I face and the emotional life which they stimulate. Most of all are we Germans devoted to this type of picturesque description, and along with it to every variety of exquisite feeling and heart effervescence such natural scenery can possibly evoke. It is a public high-road over which all may march in line. Even some of the odes of Klopstock are tuned to its key.
(c) But thirdly, if we inquire whether there is not a profounder relation between these opposed aspects of the internal feeling and external object, we shall find our nearest approach to an answer in the ancient epigram.
