"So for Instance, in Children; they perceive and forget a hundred Things in an Hour; the Brain is so soft that it receives immediately all Impressions like Water or liquid Mud, and retains scarce any of them: All the Traces, Forms or Images which are drawn there, are immediately effaced or closed up again, as though you wrote with your Finger on the Surface of a River or on a Vessel of Oil."
— Watts, Isaac (1674-1748)
