(_αα_) The most obvious reason of this necessity is referable to the fact that Art in general tends instinctively to particularization. The effect of the scientific faculty is that what is particular and singular fails to receive its complete vindication. And this is so not merely because the understanding apprehends the manifold, as such theoretic faculty, starting from its principles of generalization, causing the particular fact thereby to evaporate in its abstract deductions and categories; but also because it makes this manifold subserve ends of purely practical import. Severe adherence to that purely relative value, which strictly belongs to the nature of the process, appears to the understanding as useless and tedious. To the conception and composition of poetry on the contrary every part, every phase in the result must remain of essential interest and vital. It dallies therefore with delight in detail, depicts the same with enthusiasm, and treats every part as an independent whole. However great, therefore, in addition the content may be of a poetical work in its central interest, the organic completeness is equally asserted in subordinate detail, precisely as in the human organism every member, every finger is rounded with exquisite delicacy in its unified completeness, and as a rule, we find in Nature that every particular existence is enclosed within a perfect world of its own. The advance of poetry is therefore more slow than that compatible with the judgments and conclusions of the understanding, where we find that, whether regarded theoretically as science or with reference to practical conduct and action, the main stress is on the final result, this rather than on the path by which it is reached. As for the degree in which poetry approaches realization in its tenderness for such detail we have already pointed out that it is not its vocation to describe with excessive diffuseness what is exterior in the form of its sensuous appearance. If it therefore undertakes extensive descriptions without making them reflect at the same time the claims and interests of soul-life it becomes heavy and tedious. Above all it must take care not to enter into deliberate rivalry with the actual detail, in its exact completeness, presented by natural fact itself. Even painting in this respect should aim at circumspection and restriction. We have therefore here and in the case of poetry a twofold point of view to consider. On the one hand we must remember that the impression is on our mental vision; and on the other the art can only place before the mind the object, which in Nature we can survey and comprehend in a single glance in a series of separate traits. For this reason it is important that poetry does not carry its elaboration of detail so far, that the vision of the whole in its entirety becomes inevitably disturbed, confused, or lost. It is obvious therefore that difficulties of an
