REDUCTIONISM is a  scientific method of analysis that divides the Whole into Parts.
The primary scientific method of biomedicine for the past 150 years is REDUCTIONISM.

Advantages of REDUCTIONISM: 
by viewing Parts as disconnected, it allows greater focus on an individual Part.  Current biomedicine tends to “assign” Diagnoses to one body organ – rather than seeing systemic disease.

(1) by limiting analysis to individual parts, REDUCTIONISM prevents seeing the connections and flow of SIGNALING throughout the Brain-Body
(2) ignores REGULATION, and therefore prevents biomedicine from understanding what causes disease and what can prevent or cure disease.

The analytic method of REDUCTIONISM leaves biomedicine considering 80% of Disease as “idiopathic” (no known cause) with a scattered approach to prevention and treatment.
