My own conclusions on the nature of poetry, in the strictest use of the word, have been in part anticipated in the preceding disquisition on the fancy and imagination. What is poetry? is so nearly the same question with, what is a poem? that the answer to the one is involved in the solution of the other. For it is a distinction resulting from the poetic genius itself, which sustains and modifies the images, thoughts, and emotions of the poet’s own mind. A poet, described in ideal perfection, brings the whole soul of man into activity, with the subordination of its faculties to each other, according to their relative worth and dignity. He diffuses a tone, and spirit of unity, that blends, and (as it were) fuses, each into each, by that synthetic and magical power, to which we have exclusively appropriated the name of imagination. This power, first put in action by the will and understanding, and retained under their irremissive, though gentle and unnoticed, control (laxis effertur habenis [it is carried onwards with loose reins—ed.]) reveals itself in the balance or reconciliation of opposite or discordant qualities: of sameness, with difference; of the general, with the concrete; the idea, with the image; the individual, with the representative; the sense of novelty and freshness, with old and familiar objects; a more than usual state of emotion, with more than usual order; judgment ever awake and steady self-possession, with enthusiasm and feeling profound or vehement; and while it blends and harmonizes the natural and the artificial, still subordinates art to nature; the manner to the matter; and our admiration of the poet to our sympathy with the poetry. “Doubtless,” as Sir John Davies observes of the soul (and his words may with slight alteration be applied, and even more appropriately to the poetic IMAGINATION)
Doubtless this could not be, but that she turns
Bodies to spirit by sublimation strange,
As fire converts to fire the things it burns,
As we our food into our nature change.
From their gross matter she abstracts their forms,
And draws a kind of quintessence from things,
Which to her proper nature she transforms
To bear them light, on her celestial wings.
Thus does she, when from individual states
She doth abstract the universal kinds;
Which then re-clothed in divers names and fates
Steal access through our senses to our minds.
Finally, GOOD SENSE is the BODY of poetic genius, FANCY its DRAPERY, MOTION its LIFE, and IMAGINATION the SOUL that is everywhere, and in each; and forms all into one graceful and intelligent whole.
