Pleasure principle (psychology)

In Freudian psychology, the pleasure principle is the psychoanalytic concept describing people seeking pleasure and avoiding suffering (pain) in order to satisfy their biological and psychological needs. Furthermore, the counterpart concept, the reality principle, describes people choosing to defer gratification of a desire when circumstantial reality disallows its immediate gratification. In infancy and early childhood, the Id rules behavior by obeying only the pleasure principle. Maturity is learning to endure the pain of deferred gratification, when reality requires it; thus, the psychoanalitic Sigmund Freud proposes that “an ego thus educated has become ‘reasonable’; it no longer lets itself be governed by the pleasure principle, but obeys the reality principle, which also, at bottom, seeks to obtain pleasure, but pleasure which is assured through taking account of reality, even though it is pleasure postponed and diminished”.
