The philosopher smiled, and owned that this was very interesting, and opened up a fresh field of inquiry. The first question there was whether the imaginative author were not rather to blame for not having gone far enough in the scientific direction in the right scientific fashion than for having taken that course at all. The famous reproach of poetry made by Huxley, that it was mostly "sensual caterwauling," might well have given the singer pause in striking the sympathetic catgut of his lyre: perhaps the strings were metallic; but no matter. The reproach had a justice in it that must have stung, and made the lyrist wish to be an atomic theorist at any cost. In fact, at that very moment science had, as it were, caught the bread out of fiction's mouth, and usurped the highest functions of imagination. In almost every direction of its recent advance it had made believe that such and such a thing was so, and then proceeded to prove it. To this method we owed not only the possession of our present happy abundance of microbes in every sort, but our knowledge of the universe in almost every respect. Science no longer waited for the apple to fall before inferring a law of gravitation, but went about with a stick knocking fruit off every bough in the hope that something suggestive would come of it. On make-believes of all kinds it based the edifices of all kinds of eternal veracities. It behooved poetry, or fiction, which was radically the same, to return to its earliest and simplest devices if it would find itself in the embrace of science, and practise the make-beliefs of its infancy. Out of so many there were chances of some coming true if they were carried far enough and long enough. In fact, the hypothetical method of science had apparently been used in the art of advertising the works in which the appetite of the new reading public was flattered. The publishers had hypothesized from the fact of a population of seventy millions, the existence of an immense body of raw, coarse minds, untouched by taste or intelligence, and boldly addressed the new fiction to it. As in many suppositions of science their guess proved true. Then why, the hardy listener who had spoken before inquired, was not make-believe the right method for the author, if it was the right method for the scientist and the publisher? Why should not the novelist hypothesize cases hitherto unknown to experience, and then go on by persistent study to find them true? It seemed to this inquirer that the mistake of fiction, when it refused longer to be called an art and wished to be known as a science, was in taking up the obsolescent scientific methods, and in accumulating facts, or human documents, and deducing a case from them, instead of boldly supposing a case, as the new science did, and then looking about for occurrences to verify it.
