Here we are put upon securing for ourselves perfectly clear conceptions as to certain relations between that so-called _poetic_ activity and _scientific_ activity of the human mind which find themselves in a singularly interesting contact in the true and worthy novel which we are going to study. Merely reminding you of the distinction with which every one is more or less familiar theoretically, that that activity which we variously call "poetic," "imaginative," or "creative," _is_ essentially synthetic, is a process of putting together, while the scientific process seems distinctively analytic, or a tearing apart; let us pass from this idea to those applications of the poetic faculty which are made whenever a scientific searcher goes further than the mere collection of facts, to classify them and to effect generalizations. This is an activity of what is well called the scientific imagination. Now what is the difference between a work of the scientific imagination and a work of the poetic imagination? Without going into subtleties, I think the shortest way to gain a perfectly clear working idea of this difference is to confine our attention to the differing results of these activities: the scientific imagination results in a formula, whose paramount purpose is to be as _short_ and as comprehensive as possible; the poetic imagination results in a created form of forms, whose paramount purpose is to be as _beautiful_ and as comprehensive as possible. For example, the well-known formula of evolution: that evolution is a process from the uniform and indefinite to the multiform and definite; that is a result of long efforts of the scientific imagination; while on the other hand Tennyson's _In Memoriam_, in which we have deep matters discussed in the most beautiful words and the most musical forms of verse, is a poetic work. And now if we pass one step farther and consider what would happen if the true scientific activity and the true poetic activity should engage themselves upon one and the same set of facts, we arrive at the novel. The great modern novelist is at once scientific and poetic: and here, it seems to me, in the novel, we have the meeting, the reconciliation, the kiss, of science and poetry. For example: George Eliot, having with those keen eyes of hers collected and analyzed and sorted many facts of British life, binds them together into a true poetic synthesis, in, for instance, _Daniel Deronda_, when instead of giving us the ultimate relations of all her facts in the shape of a formula, like that of evolution, she gives them to us in the beautiful creation of Gwendolen Harleth and all the other striking forms which move through the book as embodiments in flesh and blood of the scientific relations between all her facts.
