One must remember that practically all of us have a number of significant learning disabilities. For example, I am grossly unmusical and cannot carry a tune. We happen to live in a society in which the child who has trouble learning to read is in difficulty. Yet we have all seen dyslexic children who have either superior visual-perception or visual-motor skills. My suspicion would be that in an illiterate society such a child would be in little difficulty and might in fact do better because of his superior visual-perception talents, while many of us who function here might do poorly in a society in which a quite different array of talents was needed in order to be successful. As the demands of society change will we acquire a new group of "minimally brain damaged?"
