Famous quotes containing the words mental and/or deficiency:
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“All rejection and negation indicates a deficiency in fertility: fundamentally, if only we were good plowland we would allow nothing to go unused, and in every thing, event, and person we would welcome manure, rain, or sunshine.”
—Friedrich Nietzsche (1844–1900)
