The Joke and Its Relation to the Unconscious by Sigmund Freud

The tormenting of the body by the troubled mind, hysteria is among the most pervasive of human disorders - yet at the same time it is the most elusive. Freud's recognition that hysteria stemmed from traumas in the patient's past transformed the way we think about sexuality. Studies in Hysteria is one of the founding texts of psychoanalysis, revolutionizing our understanding of love, desire and the human psyche.
