In poetry this accuracy, this rigour in unfolding the content as we find it in its simplicity, is not alone the essential principle. On the contrary, though prose is forced to confine its ideas on parallel lines of almost mathematical precision with the nature of its content, poetry introduces us to a different sphere altogether, that is, the _visible appearance_ of the content itself, or other natural phenomena related to it. For it is just this objective reality which in poetry ought to appear, and while unquestionably from one point of view revealing that content, yet at the same time from another it has to liberate itself from the purely abstract content, it being essentially an object of the art to direct attention to its actual existence in the visible world, and to arouse the interest of mind in the forms of life itself. (_c_) If these three essential requirements of poetry are conditioned by an age, in which the accuracy of the prosaic mind is become the ordinary type of conscious life, the art, so far as its figurative characteristics are concerned, is placed in a more difficult position. That is to say, in such an epoch the type of penetration exercised by conscious life is generally a separation of emotion and the ordinary outlook from scientific thought, which either converts the ideal and external material of feeling and perception into a stimulus of knowledge and volition simply, or into a plastic medium subservient to observation and action. In such a sphere poetry calls for energies of more definite purpose in order that it may free itself from the abstraction of the prevailing mental attitude and enter into the world of concrete life. Where, however, such a goal is realized, not only do we find that this breach between thinking, which makes for generalization, and perception and feeling, which grasp the particular, vanishes, but these last-mentioned modes of conscious life are, together with their subject-matter and content, at the same time freed from their exclusive relation of service; and the process culminates in a victorious reconciliation of such modes with what is essential universality. Inasmuch, however, as both the modes of poetic and prosaic thought and general outlook are united in one and the same conscious life, we find in it indications of trouble and derangement, even possibly an actual conflict between the two, one which, as the poetry of our times testifies, only genius of the highest order is able successfully to deal with. Added to this there are other collateral hindrances, which I only propose to define now, and that briefly, in their relation to the figurative aspect already discussed. In other words, if the prosaic intelligence takes the place of that creative imagination which previously obtained, then and in that case the rejuvenescence of the poetic faculty, both in all that is associated with the positive expression of facts and what is metaphorical, readily
