In every kind of Art there is a degree of excellence which may be reached, so to speak, by the mere use of one's own natural talents. But at the same time it is impossible to go beyond that point, unless Art comes to one's aid.
In the presence of Nature even moderate talent is always possessed of insight; hence drawings from Nature that are at all carefully done always give pleasure.
To make many sketches issue at last in a complete work is something that not even the best artists always achieve.
In the sphere of true Art there is no preparatory school, but there is a way of preparation; and the best preparation is the interest of the most insignificant pupil in the work of the master. Colour-grinders have often made excellent painters.
If an artist grasps Nature aright and contrives to give its form a nobler, freer grace, no one will understand the source of his inspiration, and every one will swear that he has taken it from the antique.
