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)
“It is easier to discover a deficiency in individuals, in states, and in Providence, than to see their real import and value.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
