What the artist is always looking for is the mode of existence in which soul and body are one and indivisible: in which the outward is expressive of the inward: in which form reveals. Of such modes of existence there are not a few: youth and the arts preoccupied with youth may serve as a model for us at one moment: at another we may like to think that, in its subtlety and sensitiveness of impression, its suggestion of a spirit dwelling in external things and making its raiment of earth and air, of mist and city alike, and in its morbid sympathy of its moods, and tones, and colours, modern landscape art is realizing for us pictorially what was realized in such plastic perfection by the Greeks. - P25
Truth in art is not any correspondence between the essential idea and the accidental existence; it is not the resemblance of shape to shadow, or of the form mirrored in the crystal to the form itself; it is no echo coming from a hollow hill, any more than it is a silver well of water in the valley that shows the moon to the moon and Narcissus to Narcissus. Truth in art is the unity of a thing with itself: the outward rendered expressive of the inward: the soul made incarnate: the body instinct with spirit. - P26
