"A painter must compensate the natural deficiencies of his art. He has but one sentence to utter, but one moment to exhibit. He cannot, like the poet or historian, expatiate."

“The art of seeing Nature, or in other words, the art of using Models, is in reality the great object, the point to which all our studies are directed.”

“Invention, strictly speaking, is little more than a new combination of those images which have been previously gathered and deposited in the memory: nothing can come of nothing.”

“A painter must not only be of necessity an imitator of the works of nature...but he must be as necessarily an imitator of the works of other painters: this appears more humiliating, but is equally true; and no man can be an artist, whatever he may suppose, upon any other terms.”

“The true test of all the arts, is not solely whether the production is a true copy of nature, but whether it answers the end of art, which is to produce a pleasing effect upon the mind.”

“If deceiving the eye were the only business of the art, there is no doubt, indeed, but the minute painter would be more apt to succeed; but it is not the eye, it is the mind, which the painter of genius desires to address; nor will he waste a moment upon those smaller objects, which only serve to catch the sense, to divide the attention, and to counteract his great design of speaking to the heart.”

“Could we teach taste or genius by rules, they would be no longer taste and genius.”
