When D.D. Palmer described humans as a "dual entity," what two aspects was he referring to?

D.D. Palmer described humans as a "dual entity" primarily in the context of "innate intelligence" and "educated intelligence." Innate intelligence refers to the inherent wisdom and natural ability within each individual to maintain health and well-being, guided by the body’s innate healing processes. This concept emphasizes the body's intrinsic nature to heal itself without external intervention.

Educated intelligence, on the other hand, pertains to the acquired knowledge and experiences that individuals gain throughout their lives. This includes education, culture, and personal development, which can sometimes lead to misunderstandings about health and well-being. The interaction between these two intelligences is vital in chiropractic philosophy, as it underlines the importance of recognizing and fostering the innate abilities of the body while also educating patients about health practices.

The other concepts, while significant in various contexts, do not capture the essence of Palmer's duality as intended in chiropractic philosophy. The body's physical components and mental aspects, as well as consciousness and subconsciousness, can influence health but are not the core of what D.D. Palmer articulated regarding the dual nature of human beings in chiropractic terms.
