Ideas fade in the Memory.       §4. Concerning the several degrees of lasting, wherewith Ideas are
— 151 —
imprinted on the Memory, we may observe, That some of them have
been produced in the Understanding, by an Object affecting the
Senses once only, and no more than once: Others, that have more
than once offer’d themselves to the Senses, have yet been little
taken notice of; the Mind, either heedless, as in Children, or other-
wise employ’d, as in Men, intent only on one thing, not setting the
stamp deep into it self. And in some, where they are set on with care
and repeated impressions, either through the temper of the Body,
or some other default, the Memory is very weak: 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.
