To return to that which, as the interpreting medium of his thoughts and conceptions, connects the artist with his fellow-men, we remark, that only on the ground of some self-realizing power, like what we have termed Poetic Truth, could what we call the Ideal ever be intelligible.
That some such power is inherent and fundamental in our nature, though differenced in individuals by more or less activity, seems more especially confirmed in this latter branch of the subject, where the phenomena presented are exclusively of the Possible. Indeed, we cannot conceive how without it there could ever be such a thing as true Art; for what might be received as such in one age might also be overruled in the next: as we know to be the case with most things depending on opinion. But, happily for Art, if once established on this immutable base, there it must rest: and rest unchanged, amidst the endless fluctuations of manners, habits, and opinions; for its truth of a thousand years is as the truth of yesterday. Hence the beings described by Homer, Shakspeare, and Milton are as true to us now, as the recent characters of Scott. Nor is it the least characteristic of this important Truth, that the only thing needed for its full reception is simply its presence,--being its own evidence.
How otherwise could such a being as Caliban ever be true to us? We have never seen his race; nay, we knew not that such a creature _could_ exist, until he started upon us from the mind of Shakspeare. Yet who ever stopped to ask if he were a real being? His existence to the mind is instantly felt;--not as a matter of faith, but of fact, and a fact, too, which the imagination cannot get rid of if it would, but which must ever remain there, verifying itself, from the first to the last moment of consciousness. From whatever point we view this singular creature, his reality is felt. His very language, his habits, his feelings, whenever they recur to us, are all issues from a living thing, acting upon us, nay, forcing the mind, in some instances, even to speculate on his nature, till it finds itself classing him in the chain of being as the intermediate link between man and the brute. And this we do, not by an ingenious effort, but almost by involuntary induction; for we perceive speech and intellect, and yet without a soul. What but an intellectual brute could have uttered the imprecations of Caliban? They would not be natural in man, whether savage or civilized. Hear him, in his wrath against Prospero and Miranda:--
