Forgetting (n.) is a content losing its energic value — not lost, since it may surface decades later in dreams, hypnosis or cryptomnesia.
Forgetting (n.) that is genuine leaves nothing that strives to return — it is complexes, not forgotten ideas, that live latently below the threshold and push to displace the others.
Forgetting (n.) extinguishes nothing: wipe ten years from the memories of a man who lived and a man who read a thousand books, and you can still tell which one read them.
Forgetting (n.) is conscious content sinking back into the unconscious when it loses its intensity; the unconscious is never at rest — a ceaseless welling-up, not an island's stable sea.
Forgetting (n.) may come not from repression above but from attraction below: a not-yet-conscious content pulls related ideas into eclipse — so the vague feeling of having overlooked something is worth a closer look.
Forgetting (n.) is like a searchlight moving on: interest lights a new area and leaves the old in the dark, where it waits, sometimes for years, to rise again.
