Carl Gustav (1875 - 1961), Swiss psychologist and psychiatrist. He differed with Freud in regarding the libido (energy or driving force) a s a will to live rather than a manifestation of the sex instinct, and holding that a neurosis is to be understood more by analysis of the patient's present problem and inadequate "adjustment" than by unearthing childhood fixations and conflicts.
