Since the definition of a concept is formulated in terms of other concepts, it
enables man, not only to identify and retain a concept, but also to establish
the relationships, the hierarchy, the integration of all his concepts and thus
the integration of his knowledge. Definitions preserve, not the chronological
order in which a given man may have learned concepts, but the logical order of
their hierarchical interdependence.
