Which of the following refers to the inherent intelligence within a living being?

The term that refers to the inherent intelligence within a living being is Innate Intelligence. This concept is foundational to chiropractic philosophy and emphasizes the natural ability of the body to maintain and regulate itself. Innate Intelligence is understood as the vital force that enables the body to adapt to its environment, heal, and function optimally without external intervention.

In the chiropractic context, this notion underlines the belief that each individual possesses an innate capacity for health and healing, and it is the chiropractor's role to remove interferences to this innate intelligence, typically through spinal adjustments. Other concepts, such as Universal Intelligence, refer to a broader idea that encompasses a universal order and intelligence found throughout all living things, while External and Artificial Intelligence do not relate to the natural biological processes inherent to living organisms. Thus, Innate Intelligence is specifically concerned with the intelligence that exists within each living being, making it the correct choice.
