Part 1 uses Collot d’Herbois’ lecture by the same title to develop a basis of understanding of the human constitution in relation to its spiritual, soul, etheric and physical parts. The authors present a conception of pathology from two essential notions: the formation of foreign bodies and the tendency to an illness similar to congenital consumption. They also offer some general elements as to how to conduct a therapy.
Part 2 shows how these elements correspond directly to the conceptions of the human being in health or illness according to the Collot d’Herbois’ approach.
Part 3 demonstrates through analysis of free pictures by the patients in charcoal and in color how we can begin to establish a diagnosis in relation to the two pathological tendencies describes. The the elements of diagnosis and therapy are assembled for the different types of depression related to the cardinal organs.
