The distinction between the accidental surface of things and the significance that may be drawn out of them is exemplified by the difference between accuracy and truth in representation. Accurate drawing is the faithful record of the facts of appearance as offered to the eye. Truth of drawing is the rendering in visible terms of the meaning and spirit of the object, the form which the object takes not simply for the eye but for the mind. A pencil sketch by Millet shows a man carrying in each hand a pail of water. The arms are drawn inaccurately, in that they are made too long. What Millet wanted to express, however, was not the physical shape of the arms, but the feeling of the burden under which the man was bending; and by lengthening the arms he has succeeded in conveying, as mere accuracy could not express it, the sensation of weight and muscular strain. In Hals' picture of the "Jester" the left hand is sketched in with a few swift strokes of the brush. But so, it "keeps its place" in relation to the whole; and it is more nearly right than if it had been made the centre of attention and had been drawn with the most meticulous precision. The hand is not accurate, but it is true. Similarly, size is an affair not of physical extent but of proportion. A figure six inches high may convey the same value as a figure six feet high, if the same proportions are observed. A statue is the presentation, not of the human body, but of the human form, and more than that, of what the form expresses. When I am talking with my friend I am aware of his physical presence detaching itself from the background of the room in which we are. But I feel in him something more. And that something more goes behind the details of his physical aspect. His eyes might be blue instead of brown, his nose crooked rather than straight; he might be maimed and disfigured by some mishap. These accidents would not change for me what is the reality. My friend is not his body, though it is by his body that he exists; the reality of my friend is what he essentially is, what he is of the spirit. A photograph of a man registers certain facts of his appearance at that moment. The eye and the mind of the artist discern the truth which underlies the surface; the artist feels his sitter not as a face and a figure, a mere body, but as a personality; and the portrait expresses a man.
