As WH Auden wrote after Freud's death, "To us he is no more a person / now but a whole climate of opinion."
“More than dead Hitler or Lenin, Roosevelt or Kennedy, more than Picasso, Eliot, or Stravinsky, more than the Beatles or Bob Dylan, Freud's influence on modern culture has been profound and long-lasting.” Phrases we can thank Freud for include: Mommy and daddy issues. Arrested development. Death wishes. Freudian slips. Phallic symbols. Anal retentiveness. Defense mechanisms. Cathartic release. Oedipus complex. Denial. Id, ego and super-ego. Libido. Death wishes. Anal retentiveness. Defence mechanisms. Displacement. Phallic symbols. Projection. Transference. And Freudian slips. Are all in common parlance and started with Freud. It's not just Freud's terminology that persists, he's an adjective in his own right.
[P1] Freud's theories have lent us a huge amount of common sayings.
