"In all these cases, Ideas in the Mind, quickly fade, and often vanish quite out of the Understanding, leaving no more footsteps or remaining Characters of themselves, than Shadows do flying over fields of Corn; and the Mind is as void of them, as if they never had been there."

"As on the land while here the Ocean gains, / In other parts it leaves wide sandy plains; / Thus in the soul while memory prevails, / The solid pow'r of understanding fails; / Where beams of warm imagination play, / The memory's soft figures melt away."

— Pope, Alexander (1688-1744)
