This foundation, together with physician-based clinical data, of course, has since identified many other causations that, when taken together and counteracted, usually bring about complete disease reversal.
He practiced his own advice, as clearly demonstrated in what amounts to a fantastic tour de force in his The Causation of Rheumatoid Disease and Many Human Cancers, a 350-page book that evaluates disparately named diseases and repeatedly demonstrates how they're related systemically--one arbitrarily classified disease grading nicely and continuously into another category.

If societies and organizations are understood as a complex related network, this sort of downward causation is a network cause, which is a nonlinear complex role of the higher level on the lower level and can never be reduced to the sum of the lower level causations.
However, as we know that causal reductionism tries to eliminate all higher level causations and cross level causation, especially to reduce downward causation to the lower level causation.
It is thus clear that there are various inter-level causations forming a complex causal network in the hierarchical structure of a complex system.
