Disease, through the ages, has been considered as a 'visitation' from afar
to the body or as 'disequilibrium' of an internal order. In practical terms
, these two concepts of disease have generated a nosology, that is a classi
fication of disease states. Genetics, in its dazzling recent advances, has
opened another conceptual framework: disease is an individual event, inasmu
ch as our growing understanding of the genetic 'terrain' makes all subjects
true individuals. Hence, it is time to abandon the old conceptual dichotom
y for a Hegelian synthesis: there are no diseases (either as visitation or
disequilibrium) only diseased individuals. ((C) Academie des sciences / Els
