Medicine has amassed huge amounts of knowledge down to very small details; and knowledge of associations, connections, links, cluster differentiations, abnormal proteins, genes, etc. The knowledge is interesting and important; however, putting the knowledge together across medical fields, to understand patterns and seek understanding of causation by thinking about what is known, experience, and observations will provide the greatest benefit to the most patients.

The bias in medicine against ever stating a cause is so strong, that when writing the book the computer kept auto-correcting “cause” to “because”. The obvious dilemma is research studies are not designed to find a cause, researchers are reluctant to state a cause, and practitioners will not act or cannot act to treat a patient until someone authoritative states a cause. Understanding causation can lead to new treatments directed at the causes of chronic disease.
