Where is Psychoanalytic Criticism coming from? And What does that mean?

First introduced to literary studies in the 1920s and 1940s, Freud's psychoanalytic criticism still survives today.

The pleasure principle craves only pleasures, and it desires instantaneous satisfaction of instinctual drives.
