I am on the contrary persuaded that by imitation only, variety, and even originality of invention, is produced. I will go further; even genius, at least what generally is so called, is the child of imitation. But as this appears to be contrary to the general opinion, I must explain my position before I enforce it.

Genius is supposed to be a power of producing excellencies which are out of the reach of the rules of art; a power which no precepts can teach, and which no industry can acquire.

This opinion of the impossibility of acquiring those beauties, which stamp the work with the character of genius, supposes that it is something more fixed than in reality it is; and that we always do, and ever did agree in opinion, with respect to what should be considered as the characteristic of genius. But the truth is, that the degree of excellence which proclaims Genius is different, in different times and different places; and what shows it to be so is, that mankind have often changed their opinion upon this matter.

When the Arts were in their infancy the power of merely drawing the likeness of any object was considered as one of its greatest efforts. The common people, ignorant of the principles of art, talk the same language even to this day. But when it was found that every man could be taught to do this, and a great deal more, merely by the observance of certain precepts; the name of Genius then shifted its application, and was given only to him who added the peculiar character of the object he represented; to him who had invention, expression, grace, or dignity; in short, those qualities, or excellencies, the power of producing which could not then be taught by any known and promulgated rules.

We are very sure that the beauty of form, the expression of the passions, the art of composition, even the power of giving a general air of grandeur to a work, is at present very much under the dominion of rules. These excellencies were, heretofore, considered merely as the effect of genius; and justly, if genius is not taken for inspiration, but as the effect of close observation and experience.

He who first made any of these observations, and digested them, so as to form an invariable principle for himself to work by, had that merit, but probably no one went very far at once; and generally, the first who gave the hint, did not know how to pursue it steadily and methodically; at least not in the beginning. He himself worked on it, and improved it; others worked more, and improved further; until the secret was discovered, and the practice made as general as refined practice can be made. How many more principles may be fixed and ascertained we cannot tell; but as criticism is likely to go hand in hand with the art which is its subject, we may venture to say, that as that art shall advance, its powers will be still more and more fixed by rules.

But by whatever strides criticism may gain ground, we need be under no apprehension that invention will ever be annihilated or subdued; or intellectual energy be brought entirely within the restraint of written law. Genius will still have room enough to expatiate, and keep always at the same distance from narrow comprehension and mechanical performance.

What we now call Genius begins, not where rules abstractedly taken end, but where known vulgar and trite rules have no longer any place. It must of necessity be, that even works of Genius, like every other effect, as they must have their cause, must likewise have their rules; it cannot be by chance that excellencies are produced with any constancy or any certainty, for this is not the nature of chance; but the rules by which men of extraordinary parts, and such as are called men of Genius, work, are either such as they discover by their own peculiar observations, or of such a nice texture as not easily to admit being expressed in words; especially as artists are not very frequently skilful in that mode of communicating ideas. Unsubstantial, however, as these rules may seem, and difficult as it may be to convey them in writing, they are still seen and felt in the mind of the artist; and he works from them with as much certainty, as if they were embodied, as I may say, upon paper. It is true, these refined principles cannot be always made palpable, like the more gross rules of art; yet it does not follow, but that the mind may be put in such a train, that it shall perceive, by a kind of scientific sense, that propriety, which words, particularly words of unpractised writers, such as we are, can but very feebly suggest.

Invention is one of the great marks of genius; but if we consult experience, we shall find that it is by being conversant with the inventions of others, that we learn to invent; as by reading the thoughts of others we learn to think.

Whoever has so far formed his taste, as to be able to relish and feel the beauties of the great masters, has gone a great way in his study; for, merely from a consciousness of this relish of the right, the mind swells with an inward pride, and is almost as powerfully affected as if it had itself produced what it admires. Our hearts, frequently warmed in this manner by the contact of those whom we wish to resemble, will undoubtedly catch something of their way of thinking; and we shall receive in our own bosoms some radiation at least of their fire and splendour. That disposition, which is so strong in children, still continues with us, of catching involuntarily the general air and manner of those with whom we are most conversant; with this difference only, that a young mind is naturally pliable and imitative; but in a more advanced state it grows rigid, and must be warmed and softened before it will receive a deep impression.
