This indolence, however, is perhaps more evident in the distribution of the criticism, which, if not careless, is exceedingly capricious. Campbell seems at first to have intended to concentrate this criticism proper in the Introduction (to which nearly the whole of the first volume is allotted), and to make the separate prefaces to the selections mainly biographical. But he does not at all keep to this rule; the main _Introduction_ itself is, if anything, rather too copious at the beginning, while it is compressed and hurried at the end: not a few of the minor pieces and less prominent poets have no criticism at all; while, in the case of those that have it, it is often extremely difficult to discover the principle of its allotment. Yet, on the whole, Campbell ought never to be neglected by the serious student; for even if his criticism were solely directed from an obsolete standpoint, it would be well to go back to it now and then as a half-way house between those about Johnson and those about Coleridge, while as a matter of fact it has really a very fair dose of universal quality.[529] [Sidenote: _Shelley: his_ Defence of Poetry.] There are several critical passages in Shelley’s _Letters_, but, as formally preserved, his criticism is limited to the _Defence of Poetry_, which, despite its small bulk, is of extreme interest.[530] It is almost the only return of its times to that extremely abstract consideration of the matter which we found prevalent in the Renaissance, and which in Shelley’s case, as in the cases of Fracastoro or of Sidney, is undoubtedly inspired by Plato. It seems to have been immediately prompted by some heresies of Peacock’s: but, as was always its author’s habit, in prose as well as in verse, he drifts “away, afar” from what apparently was his starting-point, over a measureless ocean of abstract thinking. He endeavours indeed, at first, to echo the old saws about men “imitating natural objects in the youth of the world” and the like, but he does not in any way keep up the arrangement, and we are almost from the outset in contact with his own ardent imagination—of which quality he at once defines poetry as the expression. Again, the poetic faculty is “the faculty of approximation to the beautiful.” Once more we have the proud claim for poetry that poets are not merely the authors of arts, but the inventors of laws, the teachers of religion. They “participate in the eternal, the infinite, and the one.” They are not necessarily confined to verse, but they will be wise to use it. A poem is the very image of life, expressed in its eternal truth. “Poetry is something divine,” the “centre and circumference of knowledge,” the “perfect and consummate surface and bloom of all things,” the “record of the best and happiest moments of the happiest and best minds.” All which (or all except the crotchet about verse) I for one do most powerfully and potently believe: though if any one says that, as generally with
