INTRODUCTION

All art is founded in science, and the science is of little value which does not serve as a foundation to some beneficial art. On the most sublime of all sciences, theology and ethics, is built the most important of all arts, the art of living. The abstract mathematical sciences serve as a groundwork to the arts of the land-measurer and the accountant; and in conjunction with natural philosophy, including geography and astronomy, to those of the architect, the navigator, the dialist, and many others. Of what consequence anatomy is to surgery, and that part of physiology which teaches the laws of gravitation and of motion, is to the artificer, is a matter too obvious to need illustration. The general remark might, if necessary, be exemplified throughout the whole circle of arts, both useful and elegant. Valuable knowledge, therefore, always leads to some practical skill, and is perfected in it. On the other hand, the practical skill loses much of its beauty and extensive utility which does not originate in knowledge. There is, by consequence, a natural relation between the sciences and the arts, like that which subsists between the parent and the offspring.

I acknowledge, indeed, that these are sometimes unnaturally separated; and that by the mere influence of example on the one hand, and imitation on the other, some progress may be made in an art, without the knowledge of the principles from which it sprang. By the help of a few rules, which men are taught to use mechanically, a good practical arithmetician may be formed, who neither knows the reasons on which the rules he works by were first established, nor ever thinks it of any moment to inquire into them. In like manner, we frequently meet with expert artisans, who are ignorant of the six mechanical powers, which, though in the exercise of their profession they daily employ, they do not understand the principles whereby, in any instance, the result of their application is ascertained. The propagation of the arts may therefore be compared more justly to that variety which takes place in the vegetable kingdom, than to the uniformity which obtains universally in the animal world; for, as to the anomalous race of zoophytes, I do not comprehend them in the number. It is not always necessary that the plant spring from the seed, a slip from another plant will often answer the purpose. There is, however, a very considerable difference in the

expectations that may justly be raised from the different methods followed in the acquisition of the art. Improvements, unless in extraordinary instances of genius and sagacity, are not to be expected from those who have acquired all their dexterity from imitation and habit. One who has had an education no better than that of an ordinary mechanic, may prove an excellent manual operator; but it is only in the well-instructed mechanician that you would expect to find a good machinist. The analogy to vegetation above suggested holds here also. The offset is commonly no more than a mere copy of the parent plant. It is from the seed only you can expect, with the aid of proper culture, to produce new varieties, and even to make improvements on The species.

“ Expert men,” says Lord Bacon, can execute and judge of particulars, one by one ; but the general councils, and the plots and marshalling of affairs, come best from those that are learned.”

Indeed, in almost every art, even as used by mere practi. tioners, there are certain rules, as hath been already hinted, which must carefully be followed, and which serve the artist instead of principles. An acquaintance with these is one step, and but one step, towards science. Thus, in the common books of arithmetic, intended solely for practice, the rules laid down for the ordinary operations, as for numeration, or numerical notation, addition, subtraction, multiplication, division, and a few others, which are sufficient for all the purposes of the accountant, serve instead of principles ; and, to a superficial observer, may be thought to supersede the study of anything farther. But their utility reaches a very little way, compared with that which results from the knowledge of the foundations of the art, and of what has been, not unfitly, styled arithmetic universal. It

may be justly said that, without some portion of this knowledge, the practical rules had never been invented. Besides, if by these the particular questions which come exactly within the description of the rule may be solved, by the other such general rules themselves, as serve for the solution of endless particulars, may be discovered.

The case, I own, is somewhat different with those arts which are entirely founded on experiment and observation, and are not derived, like pure mathematics, from abstract and universal axioms. But even in these, when we rise from the individual to the species, from the species to the genus,

and thence to the most extensive orders and classes, we arrive, though in a different way, at the knowledge of general truths, which, in a certain sense, are also scientific, and answer a

knowledge we have thus acquired, but to determine before hand, with sufficient certainty, the success of every new application. In this progress we are like people who, from a low and narrow bottom, where the view is confined to a few acres, gradually ascend a lofty peak or promontory. The prospect perpetually enlarging as we mount; and when we reach the sumit, the boundless horizon, comprehending all the variety of sea and land, hill and valley, town and country, arable and desert, lies under the eye at once.

Those who in medicine have scarcely risen to the discernment of any general principles, and have no other directory but the experiences gained in the first and lowest stage, or, as it were, at the foot of the mountain, are commonly distinguished by the name of empirics. Something similar may be said to obtain in the other liberal arts; for in all of them more enlargement of mind is necessary than is required for the exercise of those called mechanical. The character directly opposite to the empiric is the visionary; for it is not in theology only that there are visionaries. Of the two extremes, I acknowledge that the latter is the worse. The first founds upon facts, but the facts are few, and commonly in his reasonings, through his imperfect knowledge of the subject, misapplied. The second often argues very consequentially from principles, which, having no foundation in nature, may justly be denominated the illegitimate issue of his own imagination. He in this resembles the man of science, that he acts systematically, for there are false as well as true theo. rists, and is influenced by certain general propositions, real or imaginary. But the difference lies here, that in the one they are real, in the other imaginary. The system of the one is reared on the firm basis of experience, the theory of the other is no better than a castle in the air. I mention characters only in the extreme, because in this manner they are best discriminated. In real life, however, any two of these, sometimes all the three, in various proportions, may be found blended in the same person.

The arts are frequently divided into the useful, and the polite, fine, or elegant : for these words are, in this application, used synonymously. This division is not coincident with that into the mechanical and the liberal. Physic, navigation, and the art of war, though properly liberal arts, fall entirely under the denomination of the useful ; whereas painting and sculpture, though requiring a good deal of manual labour, and in that respect more nearly related to the mechanical, belong to the class denominated elegant. The first division arises purely from the consideration of the end to be attained, the second from the consideration of the means to be employed. In respect of the end, an art is either useful or elegant ; in respect of the means, it is either mechanical or liberal. The

true foundation of the former distribution is, that certain arts are manisestly and ultimately calculated for profit or use ; while others, on the contrary, seem to terminate in pleasing. The one supplies a real want, the other only gratifies some mental taste. Yet in strictness, in the execution of tre useful arts, there is often scope for elegance, and the arts called elegant are by no means destitute of use. The principal difference is, that use is the direct and avowed purpose of the former, whereas it is more latently and indirectly effected by the latter. Under this class are commonly included, not only the arts of the painter and the statuary, but those also of the musician and the poet. Eloquence and architecture, by which last term is always understood more than building merely for accommodation, are to be considered as of a mixed na. ture, wherein utility and beauty have almost equal influence.

The elegant arts, as well as the useful, are founded in experience ; but from the difference of their nature, there arises à considerable difference both in their origin and in their growth. Necessity, the mother of invention, drives men, in ihe earliest state of society, to the study and cultivation of the useful arts ; it is always leisure and abundance which lead men to seek gratifications no way conducive to the preserva. tion either of the individual or of the species. The elegant arts, therefore, are doubtless to be considered as the younger sisters. The progress of the former towards perfection is, however, much slower than that of the latter. 'Indeed, with regard to the first, it is impossible to say, as to several arts, what is the perfection of the art ; since we are incapable of conceiving how far the united discernment and industry of men, properly applied, may yet carry them. For some centuries backward, the men of every age have made great and unexpected improvements on the labours of their predeces. sors. And it is very probable that the subsequent age will produce discoveries and acquisitions, which we of this age are as little capable of foreseeing, as those who preceded us in the last century were capable of conjecturing the progress that would be made in the present. The case is not entirely similar in the fine arts. These, though later in their appear. ing, are more rapid in their advancement. There may, indeed, be in these a degree of perfection beyond what we have experienced ; but we have some conception of the very utmost to which it can proceed. For instance, where resemblance is the object, as in a picture or a statue, a perfect conformity to its archetype is a thing at least conceivable. In like manner, the utmost pleasure of which the imagination is susceptible by a poetical narrative or exhibition is a thing, in my judgment, not inconceivable. We Britons, for example, do, by immense degrees, excel the ancient Greeks in the arts of navigation and ship-building; and how much farther we

may still excel them in these, by means of discoveries and improvements yet to be made, it would be the greatest presumption in any man to say. But as it requires not a prophetic spirit to discover, it implies no presumption to affirm, that we shall never excel them so far in poetry and eloquence, if ever in these respects we come to equal them. The same thing might probably be affirmed in regard to painting, sculpture, and music, if we had here as ample a fund of materials for forming a comparison.

But let it be observed, that the remarks now made regard only the advancement of the arts themselves; for though the useful are of slower growth than the other, and their utmost perfection cannot always be so easily ascertained, yet the acquisition of any one of them by a learner, in the perfection which it has reached at the time, is a much easier matter than the acquisition of any of the elegant arts; besides that the latter require much more of a certain happy combination in the original frame of spirit, commonly called genius, than is necessary in the other.

Let it be observed farther, that as the gratification of taste is the immediate object of the fine arts, their effect is in a manner instantaneous, and the quality of any new production in these is immediately judged by everybody; for all have in them some rudiments of taste, though in some they are improved by a good, in others corrupted by a bad education, and in others almost suppressed by a total want of education. In the useful arts, on the contrary, as more time and experience are requisite for discovering the means by which our accommodation is effected, so it generally requires examination, time, and trial, that we may be satisfied of the fitness of the work for the end proposed. In these we are not so near apt to consider ourselves as judges, unless we be either artists, or accustomed to employ and examine the works of artists in that particular profession.

I mentioned some arts that have their fundamental principles in the abstract sciences of geometry and arithmetic, and some in the doctrine of gravitation and motion. There are others, as the medical and chirurgical arts, which require a still broader foundation of science in anatomy, the animal economy, natural history, diseases and remedies. Those arts, which, like poetry, are purely to be ranked among the elegant, as their end is attained by an accommodation to some internal taste, so the springs by which alone they can be regulated must be sought for in the nature of the human mind, and more especially in the principles of the imagination. It is also in the human mind that we must investigate the source of some of the useful arts. Logic, whose end is the discovery of truth, is founded in the doctrine of the understanding ; and ethics, under which may be comprehended
