What term describes the intelligence that living beings are thought to possess inborn within them?

The term that describes the intelligence believed to be inborn within living beings is "innate." In chiropractic philosophy, particularly as articulated by the founders of the discipline, the concept of innate intelligence refers to the inherent capability of the body to maintain health and facilitate healing. This innate intelligence is thought to be a guiding force that underscores the body's physiological processes, aligning with the belief that the body is self-organizing and self-healing.

In contrast, other terms do not appropriately reflect this concept. "Acquired" refers to intelligence or abilities gained through experience or education rather than being inherent. "Artificial" denotes something created by human effort rather than occurring naturally in living beings. "Collective" pertains to shared intelligence or knowledge of a group, rather than that which is individual and innate to each organism. Therefore, "innate" is the most fitting term to describe this intrinsic intelligence in chiropractic philosophy.
