Though it has been our purpose, throughout this discourse, to direct our inquiries mainly to the essential Elements of the subject, it may not be amiss here to take a brief notice of their collateral product in those mixed modes from which we derive so large a portion of our mental gratification: we allude to the various combinations of the several Ideas, which have just been examined, with each other as well as with their opposites. To this prolific source may be traced much of that many-colored interest which we take in their various forms as presented by the imagination,--in every thing, indeed, which is true, or even partially true, to the great Principle of Harmony, both in nature and in art. It is to these mixed modes more especially, that we owe all that mysterious interest which gives the illusion of life to a work of fiction, and fills us with delight or melts with woe, whether in the happiness or the suffering of some imagined being, uniting goodness with beauty, or virtue with plainness, or uncommon purity and intellect even with deformity; for even that may be so overpowered in the prominent harmony of superior intellect and moral worth, as to be virtually neutralized, at least, to become unobtrusive as a discordant force. Besides, it cannot be expected that _complete_ harmony is ever to be realized in our imperfect state; we should else, perhaps, with such expectation, have no pleasures of the kind we speak of: nor is this necessary, the imagination being always ready to supply deficiencies, whenever the approximation is sufficiently near to call it forth. Nay, if the interest felt be nothing more than mere curiosity, we still refer to this presiding Principle; which is no less essential to a simple combination of events, than to the higher demands of Form or Character. But its presence must be felt, however slightly. Of this we have the evidence in many cases, and, perhaps, most conclusive where the partial harmony is felt to verge on a powerful discord; or where the effort to unite them produces that singular alternation of what is both revolting and pleasing: as in the startling union of evil passions with some noble quality, or with a master intellect. And here we have a solution of that paradoxical feeling of interest and abhorrence, which we experience in such a character as King Richard.
