Quotation by Margaret Bancroft

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.
