Imagination is active and acts while “hovering between images,” and when it fixes on a given image, it then becomes understanding. Communication of these images of the understanding is what Coleridge terms 'noetic ideation'. “Communication by the symbolic use of the Understanding is the function of Queen Imagination on behalf of Noetic Ideation.” In contrast, fancy is static and idealising, creating nothing real, but it does, as Colerdige notes, provide a “drapery” for the body of thought. The power of imagination is evident in the relationship of reality between parts and whole, and the ability thereby to associate parts of the same whole (phenomenon) (association by contiguity) that are not ordinarily so associated in time and space (association by continuity), "the perception of similitude in dissimilitude" which "principle is the great spring of the activity of our minds, and their chief feeder." (Wordsworth's Preface to the Lyrical Ballads) Indeed, it is in the ability to see what is similar in what appears dissimilar, and what is dissimilar in what presents as similar (continuity) that resides the creative genius of a man. Art is an artificial arrangement, that is to say, not that of crude nature, but nature re-arranged is “re-presented” to the mind of man so that there is a condensed unity of parts in a given representation (compare Literature with History). It is not an illusion, but a re-creation of nature's innate unity, unconscious and promiscuous, into a new unity. In re-presenting nature, the “poet” is not simply copying or distorting nature. But in order to do so, he "must master the essence, the "natura naturans", which presupposes a bond between nature in the higher sense and the soul of man" or human nature. The wisdom of nature, the primal wisdom, is in man in the form of the body; it is participative, unconscious and instantaneous (instinctual). The wisdom of man has to be produced, re-created and given a conscious value or appraisal. It needs to be made coadunative, compresent by an act of will through objective feeling and noetic ideation. In this regard, the body wisdom (Walter Cannon) is striving to become conscious wisdom "in the human mind above nature."
