(_γ_) We have, therefore, two distinct spheres of consciousness, that of poetry and prose. In former times, in which there is neither present a deliberate outlook on the world elaborated, in respect to its religious belief and its general knowledge, under the co-ordinated form of scientific ideas and cognition, nor an actual world of human condition regulated conformably to such a standard, poetry is confronted with a lighter task. Prose is not in such a case opposed to it as an essentially independent field of ideal and external existence, which it has first to overcome. Its problem is for the most part simply limited to deepening all that is significant or transparent in the forms of ordinary consciousness. If, on the contrary, the prose of life has already appropriated within its mode of vision the entire content of conscious life, setting its seal on all and every part of it, the art of poetry is forced to undertake the task of melting all down again and re-coining the same anew. In every direction it finds itself involved in difficulties by the unresponsive nature of prosaic existence. It has, in short, not only to wrest itself from the adherence of ordinary consciousness to all that is indifferent and contingent, and to raise the scientific apprehension of the cosmos of fact to the level of reason's profounder penetration, or to translate speculative thought into terms of the imagination, giving a body to the same in the sphere of intelligence itself; it has further to convert in many ways the _mode of expression_ common to the ordinary consciousness into that appropriate to poetry; and, despite of all deliberate intention enforced by such a contrast and such a process, to make it appear as though all such purpose was absent, preserving the original freedom essential to all art. (_c_) We have now summarized in its most general terms that in which the content of poetry consists. We have further distinguished the form of poetry from that of prose. In conclusion, it is of importance to draw attention to the particularization which the art of poetry, to a degree unattained by the other arts, whose development is not nearly so rich in results, admits of. We find, no doubt, architecture illustrated in the arts of very varied peoples, and continuous through many centuries. But of sculpture, at least, it is true that it reaches its culminating point in the ancient world of Greece and Rome, just as painting and music have done more recently in Christendom. The art of poetry celebrates its epochs of brilliancy and bloom among all nations and in all ages almost that present any real artistic activity at all. It embraces the collective Spirit of mankind, and it is differentiated through every kind of variation.
