Abstract
… there is a continuity of natural ability reaching from one knows not what height, and descending to one can hardly say what depth. I propose … to range men according to their natural abilities, putting them into classes represented by equal degrees of merit, and to show the relative number of individuals included in the several classes … The method I shall employ for discovering all this is an application of the very curious theoretical law of “deviation from an average”.
