Which of the following best describes D.D. Palmer's philosophy of chiropractic?

D.D. Palmer's philosophy of chiropractic is best characterized by a broader understanding of health and the body that integrates various aspects of human experience, making it align more closely with a postmodern worldview. Postmodernism emphasizes multiple perspectives and often challenges traditional narratives and authority. In the context of chiropractic, this allows for an appreciation of the diverse factors influencing health, including psychological, social, and cultural aspects, rather than solely focusing on mechanical adjustments.

By promoting a holistic view of health, Palmer advocated for considering the body as more than just a physical entity that can be manipulated. His philosophy encouraged practitioners to explore different paths to healing, emphasizing self-healing and the body's innate intelligence. This perspective resonates with postmodern ideas that reject a single, authoritative approach to understanding the world and health.

The other options do not encapsulate Palmer’s philosophy as effectively. While manual manipulation is a significant part of chiropractic practice, Palmer's worldview extended beyond just the physical techniques. Scientific inquiry plays a role in chiropractic, and while its application has evolved over the years, Palmer did not advocate avoiding it outright. Lastly, strictly adhering to historical methods would be contrary to the evolving nature of chiropractic philosophy, which seeks to integrate new findings and understandings rather than remain static.
