The opposite of remembering is usually called forgetting. An important still open question is psychology is ‘learn to forget’, and if not, why not?

The common definitions of the word ‘forget; include ‘to put out of one’s mind’ meaning the active or intentional overlooking of an object, an insult and so on.
