Life being very short, and the quiet hours of it few, we ought to waste none of them in reading valueless books. - John Ruskin

The entire vitality of art depends upon its being either full of truth, or full of use; and that, however pleasant, wonderful, or impressive it may be in itself, it must yet be of inferior kind, and tend to deeper inferiority, unless it has clearly one of these main objects, — either to state a true thing, or to adorn a serviceable one.

The zealous care with which J. M. W. Turner endeavoured to do his duty, is proved by a large existing series of drawings, exquisitely tinted, and often completely coloured, all by his own hand, of the most difficult perspective subjects—illustrating not only directions of line, but effects of light - with a care and completion which would put the work of any ordinary teacher to utter shame. In teaching generally — he would neither waste time nor spare it - he would look over a student's drawing at the Academy, point to a defective part, make a scratch on the paper at the side, say nothing. If the student saw what was wanted, and did it, Turner was delighted; but if the student could not follow. Turner left him.
