Versification, or the art of modulating his numbers, is indispensably necessary to a poet. Every other power by which the understanding is enlightened, or the imagination enchanted, may be exercised in prose. But the poet has this peculiar superiority, that to all the powers which the perfection of every other composition can require, he adds the faculty of joining music with reason, and of acting at once upon the senses and the passions. I suppose there are few who do not feel themselves touched by poetical melody, and who will not confess that they are more or less moved by the same thoughts, as they are conveyed by different sounds, and more affected by the same words in one order than another. The perception of harmony is, indeed, conferred upon men in degrees very unequal; but there are none who do not perceive it, or to whom a regular series of proportionate sounds cannot give delight. (SAMUEL JOHNSON: _The Rambler_, No. 86.) Various causes might be pointed out why, when the style is manly, and the subject of some importance, words metrically arranged will long continue to impart such a pleasure to mankind as he who proves the extent of that pleasure will be desirous to impart. The end of poetry is to produce excitement in coexistence with an overbalance of pleasure; but, by the supposition, excitement is an unusual and irregular state of the mind; ideas and feelings do not, in that state, succeed each other in accustomed order.... Now the co-presence of something regular, something to which the mind has been accustomed in various moods and in a less excited state, cannot but have great efficacy in tempering and restraining the passion by an intertexture of ordinary feeling, and of feeling not strictly and necessarily connected with the passion. This is unquestionably true; and hence, though the opinion will at first appear paradoxical, from the tendency of metre to divest language, in a certain degree, of its reality, and thus to throw a sort of half-consciousness of unsubstantial existence over the whole composition, there can be little doubt but that more pathetic situations and sentiments--that is, those which have a greater proportion of pain connected with them--may be endured in metrical composition, especially in rime, than in prose.... This opinion may be further illustrated by appealing to the reader's own experience of the reluctance with which he comes to the reperusal of the distressful parts of _Clarissa Harlowe_, or the _Gamester_; while Shakspere's writings, in the most pathetic scenes, never act upon us as pathetic beyond the bounds of pleasure--an effect which, in a much greater degree than might at first be imagined, is to be ascribed to small, but continual and regular impulses of pleasurable surprise from the metrical arrangement.[56] On the other hand (what it must be allowed will much more frequently happen), if the poet's words should be incommensurate with the passion, and inadequate to raise the
