Abstract
Human beings have developed an impressive capacity to discriminate: to arrange their perception of the world into precise entities to which they then give names so that they can communicate about them. In achieving this feat they have, however, become very dependent on this ability. Indeed, we may wonder whether it has become counterproductive. In contemporary society everything that is studied, and the methods by which it is studied, are divided into categories. It has now come to a point where, to be considered a person of worth, one must be a specialist.
