The poetic spirit is immortal, nor can it disappear from humanity; it can only disappear with humanity itself, or with the aptitude to be a man, a human being. And actually, though man by the freedom of his imagination and of his understanding departs from simplicity, from truth, from the necessity of nature, not only a road always remains open to him to return to it, but, moreover, a powerful and indestructible instinct, the moral instinct, brings him incessantly back to nature; and it is precisely the poetical faculty that is united to this instinct by the ties of the closest relationship. Thus man does not lose the poetic faculty directly he parts with the simplicity of nature; only this faculty acts out of him in another direction. Even at present nature is the only flame that kindles and warms the poetic soul. From nature alone it obtains all its force; to nature alone it speaks in the artificial culture-seeking man. Any other form of displaying its activity is remote from the poetic spirit. Accordingly it may be remarked that it is incorrect to apply the expression poetic to any of the so-styled productions of wit, though the high credit given to French literature has led people for a long period to class them in that category. I repeat that at present, even in the existing phase of culture, it is still nature that powerfully stirs up the poetic spirit, only its present relation to nature is of a different order from formerly. As long as man dwells in a state of pure nature (I mean pure and not coarse nature), all his being acts at once like a simple sensuous unity, like a harmonious whole. The senses and reason, the receptive faculty and the spontaneously active faculty, have not been as yet separated in their respective functions: _à fortiori_ they are not yet in contradiction with each other. Then the feelings of man are not the formless play of chance; nor are his thoughts an empty play of the imagination, without any value. His feelings proceed from the law of necessity; his _thoughts_ from _reality_. But when man enters the state of civilization, and art has fashioned him, this _sensuous_ harmony which was in him disappears, and henceforth he can only manifest himself as a _moral unity_, that is, as aspiring to unity. The harmony that existed as a _fact_ in the former state, the harmony of feeling and thought, only exists now in an _ideal_ state. It is no longer in him, but out of him; it is a conception of thought which he must begin by realizing in himself; it is no longer a fact, a reality of his life. Well, now let us take the idea of poetry, which is nothing else than _expressing humanity as completely as possible_, and let us apply this idea to these two states. We shall be brought to infer that, on the one hand, in the state of natural simplicity, when all the faculties of man are exerted together, his being still manifests itself in a harmonious unity, where, consequently, the _totality_ of his nature expresses
