My entire delight was in observing without being myself noticed,- if I could have been invisible, all the better. . . to be in the midst of it, and rejoice and wonder at it, and help it if I could, - happier if it needed no help of mine, - this was the essential love of Nature in me, this the root of all that I have usefully become, and the light of all that I have rightly learned.

Our purity of taste is best tested by its universality, for if we can only admire this thing or that, we maybe use that our cause for liking is of a finite and false nature.

Nothing can be true which is either complete or vacant; every touch is false which does not suggest more than it represents, and every space is false which represents nothing.

The names of great painters are like passing-bells: in the name of Velasquez you hear sounded the fall of Spain; .in the name of Titian, that of Venice; in the name of Leonardo, that of Milan; in the name of Raphael, that of Rome. And there is profound justice in this, for in proportion to the nobleness of the power is the guilt of its use for purposes vain or vile; and hitherto the greater the art, the more surely has it been used, and used solely, for the decoration of pride or the provoking of sensuality.

Humanity and Immortality consist neither in reason, nor in love; not in the body, nor in the animation of the heart of it, nor in the thoughts and stirrings of the brain of it;--but in the dedication of them all to Him who will raise them up at the last day.

You will never love art well until you love what she mirrors better.
