Modern psychology has demonstrated that this is the way in which the creative artistic imagination proceeds. It has proved that a vast portion of all our thinking goes on unconsciously; and that the results may arise into consciousness piecemeal and gradually, checking each other as they come; or that they may come all at once, with all the completeness and definiteness of perceptions presented from without. The former is the case with the critical, and the latter with the artistic intellect. And this we recognize imperfectly when we talk of a genius being "inspired." All of us probably have these two kinds of imagination to a certain extent. It is only given to a few supremely endowed persons like Goethe to possess them both to an eminent degree. Perhaps of no other man can it be said that he was a poet of the first order, and as great a critic as poet. It is therefore apt to be a barren criticism which studies the works of creative geniuses in order to ascertain what theory lies beneath them. How many systems of philosophy, how many subtle speculations, have we not seen fathered upon Dante, Cervantes, Shakespeare, and Goethe! Yet their works are, in a certain sense, greater than any systems. They partake of the infinite complexity and variety of nature, and no more than nature itself can they be narrowed down to the limits of a precise formula. Lessing was wont to disclaim the title of poet; but, as Goethe said, his immortal works refute him. He had not only poetical, but dramatic genius; and his "Emilia Galotti" has kept the stage until to-day. Nevertheless, he knew well what he meant when he said that he was more of a critic than a poet. His genius was mainly of the critical order; and his great work, "Nathan the Wise," was certainly constructed rather than created. It was intended to convey a doctrine, and was carefully shaped for the purpose. And when we have pronounced it the greatest of all poems that have been written for a set purpose, and admit of being expressed in a definite formula, we have classified it with sufficient accuracy. For an analysis of the characters in the poem, nothing can be better than the essay by Kuno Fischer, appended to the present volume. The work of translation has been admirably done; and thanks are due to Miss Frothingham for her reproduction of this beautiful poem. June, 1868. VIII. HISTORICAL DIFFICULTIES.
