"Perhaps no man can be a poet, or can even enjoy poetry, without a certain unsoundness of mind,--if anything which gives so much pleasure ought to be called unsoundness. By poetry we mean not, of course, all writing in verse, nor even all good writing in verse. Our definition excludes many metrical compositions which on other grounds deserve the highest praise. By poetry we mean the art of employing words in such a manner as to produce an illusion on the imagination; the art of doing by means of words what the painter does by means of colors. Thus the greatest of poets has described it, in lines universally admired for the vigor and felicity of their diction, and still more valuable on account of the just notion which they convey of the art in which he excelled. "'As imagination bodies forth The forms of things unknown, the poet's pen Turns them to shapes, and gives to airy nothing A local habitation and a name.' "These are the fruits of the 'fine frenzy' which he ascribes to the poet,--a fine frenzy doubtless, but still a frenzy. Truth, indeed, is essential to poetry, but it is the truth of madness. The reasonings are just, but the premises are false. After the first suppositions have been made, everything ought to be consistent; but those first suppositions require a degree of credulity which almost amounts to a partial and temporary derangement of the intellect. Hence, of all people, children are the most imaginative. They abandon themselves without reserve to every illusion. Every image which is strongly presented to their mental eye produces on them the effect of reality. No man, whatever his sensibility may be, is ever affected by Hamlet or Lear as a little girl is affected by the story of poor Red-Riding-Hood. She knows that it is all false, that wolves cannot speak, that there are no wolves in England. Yet in spite of her knowledge she believes; she weeps; she trembles; she dares not go into a dark room, lest she should feel the teeth of the monster at her throat. Such is the despotism of the imagination over uncivilized minds." In other words, such is the despotism of suggestion over the subjective mind. No truer statement of the methods of subjective mental action could be written. "The reasonings are just, but the premises are false," says Macaulay. True, the deductive reasonings of the subjective mind are always just, logical, syllogistically perfect, and are equally so whether the premises are false or true.
