In a normal person the motor and sensory nervous systems act as the windows of the individual personality.... [ellipsis in original] The broken, many-stained and pictorial windows through which the light is struggling under disadvantages to harmonize itself with the physical world at large are found in three classes of persons—the mentally deficient, the morally deficient, and the insane. In these, the light is there, but the images, as in a broken cathedral window, are more or less shattered and confused.
Margaret Bancroft (1854–1912), U.S. educator. As quoted in Past and Promise, part 3, by Shirley M. Montgomery (1990).
From an article written in 1904. Bancroft was an early specialist in the education of children with learning disabilities and mental retardation. She co-founded the Bancroft Training School in Haddonfield, New Jersey.
