(b) The second aspect of externality is the relation it occupies directly in the various material which art employs in the various media of its presentations. The unity here consists in the clear definition and homogeneousness of the material, which ought not to deviate in the direction of a vague characterization and mere confusion, or, speaking generally, give us the impression of dirtiness. This determinacy is also entirely dependent upon the spatial condition, that is to say, upon the purity of its delineation, the distinctness of its rectilinear and circular lines, and so on, no less than upon a consistent definition of Time such as we find in the accurate measure of the musical beat. It depends furthermore on the translucency both of specific tones and colours. In a good picture we shall find that there is nothing unclean or "dirty"[376] in the colours employed, but everything is clear and asserts itself openly for what it is. The directness of its purity is, in fact, that which constitutes the lovely impression of colour upon our sense; and those colours which are most direct in their simplicity, such as a yellow which has no dash of green in it, or a red that is wholly independent of blue or yellow, produce the most emphatic effect. On the other hand, it is obviously more difficult to maintain a harmony of the whole when colours are thus contrasted in all their pristine simplicity. Yet in despite of this these essentially simple colours form the foundation of every true colour scheme, and although it may be impossible to dispense with a considerable use of their compounds, even these should not be allowed to appear in one dead and dull interfusion, but with their simple and luminous derivations shining through them[377]; otherwise instead of the clear lambency of colour we shall get nothing but a muddy residuum. We shall find that the same thing is necessary in the timbre of musical tone. In the case of strings whether of metal or catgut it is the vibration of the material, and, moreover, of a material of definite tension and length, which educes the musical note. If the tension is insufficient, or the length of the string which is struck is not the right one, the tone inevitably loses its clearness of definition, rings false, as we say, owing to the interfusion with it of other tones[378]. We have the same kind of result when a purely mechanical fretting or scraping is suffered to interfere with the purity of the vibratory motion, and so to render the emitted sound confused and harsh. In the same way, it is of the first importance to the art of singing that the human voice should be produced from throat and chest freely and with purest intonation; the voice should be heard without the least indication of its organic instrument, or, as in the case of hoarseness, with an obstructive accompaniment the singer fails to repress. We may conclude, then, that this translucency and purity, free from all admixture with anything foreign to it, and consistent throughout in its clearness, is that which creates the beauty of tone as immediately apprehended by our senses, and which distinguishes it from every kind of mere noise. And we may add further it is this which in human speech conspicuously applies to the articulation of the vowels. A language which enunciates the five vowels with distinction and purity, as is strongly the case in the Italian, is essentially musical and adapted to song. The diphthongs, on the contrary, always produce a confused tone. In literature little attention is paid to the direct reproduction of folk-dialects; we find them rather reduced to the simplest form of expression. In actual speech, however, this clearness of intonation only too often entirely disappears, so that we find, and markedly so in the case of dialects such as the South German, Swabian, and Swiss, men actually speak with an articulation of sound it is quite impossible to write down. We do not regard this, however, to be necessarily a defect in human speech, but rather a reflection of the rawness of the common folk. And here we must close our observations upon that external aspect of art, which, from the fact that it is external, and nothing more, is only capable of receiving an external and abstract unity.

Now according to its more comprehensive definition it is the concrete individuality of the Ideal impregnated with reason, which takes to itself externality as the form of its embodiment, and, moreover, in such a way that the external semblance, which is thus the medium of its expression, is throughout suffused with the mind inherent in this concrete individual form. In consequence of this such modes of relation as uniformity, symmetry, and harmony, or, in other words, the more simple determinations of the sensuous material are no longer adequate. This defect naturally extends our inquiry to that second aspect of the external determination of the Ideal already stated.

2. THE COALESCENCE OF THE CONCRETE IDEAL WITH ITS EXTERNAL REALITY

The fundamental truth which we shall endeavour to substantiate before everything in the matter which now immediately engages our attention is this, that man is under an obligation to make himself at peace and at home in the environment of the world; or, to put it rather differently, his individuality must live itself into Nature and all the conditions of that external world, and by doing so assert its freedom visibly. And, moreover, this must take place in such a way that these two related factors, that is, on the one side, the entirety of his inward life and the character it possesses or displays in all conditions or actions whatsoever, and, on the other, that objective entirety of external existence which confronts him, must wholly lose the appearance of two worlds which are either indifferent to or not homogeneous with[379] each other, and forthwith proclaim themselves as harmoniously related and identical in substance. This externally objective world must, in so far as it is the reality of the Ideal, surrender the semblance of its own objective self-subsistency and stubbornness, in order that its fundamental unity with that to which it supplies the external and particular embodiment may be exhibited in truth.

To establish this unity with more conclusiveness we propose now to examine our subject under three different heads of discussion.

First, we may investigate the same from the point of view that this unity which binds the two factors already defined is merely a bond which possesses no positive reality[380], but is merely a mysterious and secret connection both in its origin and appearance, by virtue of which our humanity is looped together with its environment.

Secondly, however, as a deduction from the fact that it is the concrete spiritual life of man and the individuality which pertains to it which constitutes the point of departure, or rather the essential content of the Ideal, we shall further examine this association, as in truth the creation of human activity itself and only possible as such a creation.

Finally, we shall prove that this unified world created by the human Spirit is itself a complete entirety, which, in the determinate form of its existence, is objectively valid, and in essential relation with which every unit of our common humanity who is actively engaged with the vital concerns of art must infallibly remain.

In opening our discussion of the position we proposed first we would at once point out an important conclusion involved in it. We have here posited that the environment of the Ideal is not directly due to human activity, it can therefore only be regarded in this first step of our inquiry as something external to man, that is to say Nature. How, then, is this something outside man to be exhibited in the ideal work of art? We will discuss this at least in its more general terms, and here, too, draw attention to three aspects of importance.
