Never judge a work of art by its defects.

Never expect justice from a vain man; if he has the negative magnanimity not to disparage you, it is the most you can expect.

He who has no pleasure in looking up, is not fit so much as to look down.

Selfishness in art, as in other things, is sensibility kept at home.

The love of gain never made a painter; but it has marred many.

No man knows himself as an original.

It is a hard matter for a man to lie all over, nature having provided king's evidence in almost every member. The hand will sometimes act as a vane, to show which way the wind blows, even when every feature is set the other way; the knees smite together and sound the alarm of fear under a fierce countenance; the legs shake with anger when all above us calm.
