"The primitive man may have taken a pleasure in beating women as well as in drawing animals; all we can say is that the drawings record the one but not the other. It may be true that when the cave-man’s finished jumping on his mother, or his wife as the case may be, he loves to hear the little brook a-gurgling, and also to watch the deer as they come down to drink at the brook. These things are not impossible, but they are irrelevant. The common sense of the child could confine itself to learning from the facts what the facts have to teach; and the pictures in the cave are very nearly all the facts there are. So far as that evidence goes, the child would be justified in assuming that a man had represented animals with rock and red ochre for the same reason as he himself was in the habit of trying to represent animals with charcoal and red chalk. The man had drawn a stag just as the child had drawn a horse; because it was fun."
