Now, the starry heavens are very happily designed to intensify the sensations on which their beauties must rest. In the first place, the continuum of space is broken into points, numerous enough to give the utmost idea of multiplicity and yet so distinct and vivid that it is impossible not to remain aware of their individuality. The variety of local signs, without becoming organized into forms, remains prominent and irreducible. This makes the object infinitely more exciting than a plane surface would be. In the second place, the sensuous contrast of the dark background, — blacker the clearer the night and the more stars we can see, — with the palpitating fire of the stars themselves, could not be exceeded by any possible device. This material beauty adds incalculably, as we have already pointed out, to the inwardness and sublimity of the effect. To realize the great importance of these two elements, we need but to conceive their absence, and observe the change in the dignity of the result.
Fancy a map of the heavens and every star plotted upon it, even those invisible to the naked eye: why would this object, as full of scientific suggestion surely as the reality, leave us so comparatively cold? Quite indifferent it might not leave us, for I have myself watched stellar photographs with almost inexhaustible wonder. The sense of multiplicity is naturally in no way diminished by the representation; but the poignancy of the sensation, the life of the light, are gone; and with the dulled impression the keenness of the emotion disappears. Or imagine the stars, undiminished in number, without losing any of their astronomical significance and divine immutability, marshalled in geometrical patterns; say in a Latin cross, with the words In hoc signo vinces in a scroll around them. The beauty of the illumination would be perhaps increased, and its import, practical, religious, and cosmic, would surely be a little plainer; but where would be the sublimity of the spectacle? Irretrievably lost: and lost because the form of the object would no longer tantalize us with its sheer multiplicity, and with the consequent overpowering sense of suspense and awe.
In a word, the infinity which moves us is the sense of multiplicity in uniformity. Accordingly things which have enough multiplicity, as the lights of a city seen across water, have an effect similar to that of the stars, if less intense; whereas a star, if alone, because the multiplicity is lacking, makes a wholly different impression. The single star is tender, beautiful, and mild; we can compare it to the humblest and sweetest of things:
A violet by a mossy stone
Half hidden from the eye,
Fair as a star when only one
Is shining in the sky.
It is, not only in fact but in nature, an attendant on the moon, associated with the moon, if we may be so prosaic here, not only by contiguity but also by similarity.
Fairer than Phoebe's sapphire-regioned star
Or vesper, amorous glow-worm of the sky.
The same poet can say elsewhere of a passionate lover:
He arose
Ethereal, flushed, and like a throbbing star,
Amid the sapphire heaven's deep repose.
How opposite is all this from the cold glitter, the cruel and mysterious sublimity of the stars when they are many! With these we have no Sapphic associations; they make us think rather of Kant who could hit on nothing else to compare with his categorical imperative, perhaps because he found in both the same baffling incomprehensibility and the same fierce actuality. Such ultimate feelings are sensations of physical tension.
