If a critic, in despair of giving a serious definition of poetry, should be satisfied with saying that poetry is metrical discourse, he would no doubt be giving an inadequate account of the matter, yet not one of which he need be ashamed or which he should regard as superficial. Although a poem be not made by counting of syllables upon the fingers, yet "numbers" is the most poetical synonym we have for verse, and "measure" the most significant equivalent for beauty, for goodness, and perhaps even for truth. Those early and profound philosophers, the followers of Pythagoras, saw the essence of all things in number, and it was by weight, measure, and number, as we read in the Bible, that the Creator first brought Nature out of the void. Every human architect must do likewise with his edifice; he must mould his bricks or hew his stones into symmetrical solids and lay them over one another in regular strata, like a poet's lines. Measure is a condition of perfection, for perfection requires that order should be pervasive, that not only the whole before us should have a form, but that every part in turn should have a form of its own, and that those parts should be coordinated among themselves as the whole is coordinated with the other parts of some greater cosmos. Leibnitz lighted in his speculations upon a conception of organic nature which may be false as a fact, but which is excellent as an ideal; he tells us that the difference between living and dead matter, between animals and machines, is that the former are composed of parts that are themselves organic, every portion of the body being itself a machine, and every portion of that machine still a machine, and so _ad infinitum_; whereas, in artificial bodies the organization is not in this manner infinitely deep. Fine Art, in this as in all things, imitates the method of Nature and makes its most beautiful works out of materials that are themselves beautiful. So that even if the difference between verse and prose consisted only in measure, that difference would already be analogous to that between jewels and clay. The stuff of language is words, and the sensuous material of words is sound; if language therefore is to be made perfect, its materials must be made beautiful by being themselves subjected to a measure, and endowed with a form. It is true that language is a symbol for intelligence rather than a stimulus to sense, and accordingly the beauties of discourse which commonly attract attention are merely the beauties of the objects and ideas signified; yet the symbols have a sensible reality of their own, a euphony which appeals to our senses if we keep them open. The tongue will choose those forms of utterance which have a natural grace as mere sound and sensation; the memory will retain these catches, and they will pass and repass through the mind until they become types of instinctive speech and standards of pleasing expression.
