Such is the warmth with which both the Ancients and Moderns speak of this divine principle of the art; but, as I have formerly observed, enthusiastic admiration seldom promotes knowledge. Though a Student by such praise may have his attention roused, and a desire excited, of running in this great career, yet it is possible that what has been said to excite may only serve to deter him. He examines his own mind, and perceives there nothing of that divine inspiration with which he is told so many others have been favoured. He never travelled to heaven to gather new ideas; and he finds himself possessed of no other qualifications than what mere common observation and a plain understanding can confer. Thus he becomes gloomy amidst the splendour of figurative declamation, and thinks it hopeless to pursue an object which he supposes out of the reach of human industry. But on this, as upon many other occasions, we ought to distinguish how much is to be given to enthusiasm, and how much to reason. We ought to allow for, and we ought to commend, that strength of vivid expression which is necessary to convey, in its full force, the highest sense of the most complete effect of art; taking care, at the same time, not to lose in terms of vague admiration that solidity and truth of principle upon which alone we can reason, and may be enabled to practise. It is not easy to define in what this great style consists; nor to describe, by words, the proper means of acquiring it, if the mind of the Student should be at all capable of such an acquisition. Could we teach taste or genius by rules, they would be no longer taste and genius. But though there neither are, nor can be, any precise invariable rules for the exercise, or the acquisition, of these great qualities, yet we may truly say, that they always operate in proportion to our attention in observing the works of Nature, to our skill in selecting, and to our care in digesting, methodising, and comparing our observations. There are many beauties in our art that seem, at first, to lie without the reach of precept, and yet may easily be reduced to practical principles. Experience is all in all: but it is not every one who profits by experience; and most people err, not so much from want of capacity to find their object, as from not knowing what object to pursue. This great ideal perfection and beauty are not to be sought in the heavens, but upon the earth. They are about us, and upon every side of us. But the power of discovering what is deformed in Nature, or, in other words, what is particular and uncommon, can be acquired only by experience; and the whole beauty and grandeur of the art consists, in my opinion, in being able to get above all singular forms, local customs, particularities, and details of every kind.
