It would seem then as if there were a distinction between these two things; that form was on one side of the fence and color on the other. Yet that would contradict our experience; for we know that everything which has a form or shape, visible to the eye, has also color that we can see. And most things that have color are seen to have a shape or form. Not all; for example, when the sky is a cloudless blue, or when we gaze over a distant expanse of sea. Still, as a general experience, color and form are identical. The face of a friend--you recognise it by its color as well as by the form of the features; and, should you have the sorrow of looking upon that face when it is dead, the change in the color would make you recognise the once familiar features as strangely different.
