Indeed, when a child is involved, the keener his use of the reasoning mind becomes the dimmer his mathematical abilities grow. Others, children [or adults] who would be classified as mentally deficient, can tell, or have been able to tell, the day of the week that any given date, past or present, would fall upon. Others have been able, while performing various tasks, to keep a precise count of the moments from any given point in time. There have been children, again, with highly accomplished musical abilities, and great facility with music’s technical aspects—all such accomplishments before the assistance of any kind of advanced education.

Some of those abilities show themselves in those classified as mentally deficient simply because all of the powers of the reasoning mind are not activated. In children under such conditions, the reasoning mind has not yet developed in all of its aspects sufficiently, so that in a certain area direct cognition shines through with its brilliant capacity.
