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. _Defects of pure multiplicity._ Sec. 26. This long analysis will be a sufficient illustration of the power of multiplicity in uniformity; we may now proceed to point out the limitations inherent in this form. The most obvious one is that of monotony; a file of soldiers or an iron railing is impressive in its way, but cannot long entertain us, nor hold us with that depth of developing interest, with which we might study a crowd or a forest of trees. The tendency of monotony is double, and in two directions deadens our pleasure. When the repeated impressions are acute, and cannot be forgotten in their endless repetition, their monotony becomes painful. The constant appeal to the same sense, the constant requirement of the same reaction, tires the system, and we long for change as for a relief. If the repeated stimulations are not very acute, we soon become unconscious of them; like the ticking of the clock, they become merely a factor in our bodily one, a cause, as the case may be, of a diffused pleasure or unrest; but they cease to present a distinguishable object.
