Remember, what we are to think of now is a drawing of a figure or object, represented simply in outline, with no added strokes to suggest light and shade. It may have been done with a pencil or brush, or in one of many other ways; but it is only outline. Now many people think the only purpose of the outline is to enclose the figure, so that we may see what the figure is. They may think the figure is beautiful, because it represents something of which they are fond; the plump body of a baby, for instance. But suppose the figure represents an old worn-out beggar, with long scraggy arms and bare, misshapen feet. Would they see any beauty in it? I expect not.
