You must interpret nature with entire simplicity and according to your personal sentiment, altogether detaching yourself from what you know of the old masters or of contemporaries. Only in this way will you do work of real feeling. I know gifted people who will not avail themselves of their power. Such
people seem to me like a billiard-player whose adversary is constantly giving him good openings, but who makes no use of them. I think that if I were playing with that man, I would say, "Very well, then, I will give you no more." If I were to sit in judgment, I would punish the miserable creatures who squander their natural gifts, and I would turn their hearts to work.
Corot.
LXXVII
Sensation is rude and false unless informed by intellection; and, however delicate be the touch in obedience to remote gradation, yet knowledge of the genus necessarily invests the representation with perspicuous and truthful relations that ignorance could not possibly have observed. Hence—Paint what you see; but know what you see.
Only paint what you love in what you see, and discipline yourself to separate this essence from its dumb accompaniments, so that the accents fall upon the points of passion. Let that which must be expressed of the rest be merged, syncopated in the largeness of the modulation.
Boldly dare to omit the impertinent or irrelevant, and let the features of the passion be modulated in fewness.
Not a touch without its meaning or its significance throughout the courses. There is no disgrace, but on the contrary, honour, be the touches never so few, if studied. By determined refusal to touch vaguely,
and with persistence in the slowness of thoughtful work, a noble style may be at length obtained: swift as sublime.
