The 33 Principles of Chiropractic are chiropractic’s core foundational philosophical tenants which were published by Ralph W. Stephenson, D.C. in his 1927 text, The Chiropractic Textbook.
| The 33 Principles of Chiropractic | |
| 1. The Major Premise | Universal Intelligence is in all matter and continually gives to it all its properties and actions, thus maintaining it in existence. |
| 2. The Chiropractic Meaning of Life | The expression of this intelligence through matter is the Chiropractic meaning of life. |
| 3. The Union of Intelligence and Matter | Life is necessarily the union of intelligence and matter. |
| 4. The Triune of Life | Life is a triunity having three necessary united factors, namely, Intelligence, Force and Matter. |
| 5. The Perfection of the Triune | In order to have 100% Life, there must be 100% Intelligence, 100% Force, 100% Matter. |
| 6. The Principle of Time | There is no process that does not require time. |
| 7. The Amount of Intelligence in Matter | The amount of intelligence for any given amount of matter is 100%, and is always proportional to its requirements. |
| 8. The Function of Intelligence | The function of intelligence is to create force. |
| 9. The Amount of Force Created by Intelligence | The amount of force created by intelligence is always 100%. |
| 10. The Function of Force | The function of force is to unite intelligence and matter. |
| 11. The Character of Universal Forces | The forces of Universal Intelligence are manifested by physical laws; are unswerving and unadapted, and have no solicitude for the structures in which they work. |
| 12. Interference with Transmission of Universal Forces | There can be interference with transmission of universal forces. |
| 13. The Function of Matter | The function of matter is to express force. |
| 14. Universal Life | Force is manifested by motion in matter; all matter has motion, therefore there is universal life in all matter. |
| 15. No Motion without the Effort of Force | Matter can have no motion without the application of force by intelligence. |
| 16. Intelligence in both Organic and Inorganic Matter | Universal Intelligence gives force to both organic and inorganic matter. |
| 17. Cause and Effect | Every effect has a cause and every cause has effects. |
| 18. Evidence of Life | The signs of life are evidence of the intelligence of life. |
| 19. Organic Matter | The material of the body of a “living thing” is organized matter. |
| 20. Innate Intelligence | A “living thing” has an inborn intelligence within its body, called Innate Intelligence. |
| 21. The Mission of Innate Intelligence | The mission of Innate Intelligence is to maintain the material of the body of a “living thing” in active organization. |
| 22. The Amount of Innate Intelligence | There is 100% of Innate Intelligence in every “living thing,” the requisite amount, proportional to its organization. |
| 23. The Function of Innate Intelligence | The function of Innate Intelligence is to adapt universal forces and matter for use in the body, so that all parts of the body will have co-ordinated action for mutual benefit. |
| 24. The Limits of Adaptation | Innate Intelligence adapts forces and matter for the body as long as it can do so without breaking a universal law, or Innate Intelligence is limited by the limitations of matter. |
| 25. The Character of Innate Forces | The forces of Innate Intelligence never injure or destroy the structures in which they work. |
| 26. Comparison of Universal and Innate Forces | In order to carry on the universal cycle of life, Universal forces are destructive, and Innate forces constructive, as regards structural. |
| 27. The Normality of Innate Intelligence | Innate Intelligence is always normal and its function is always normal. |
| 28. The Conductors of Innate Forces | The forces of Innate Intelligence operate through or over the nervous system in animal bodies. |
| 29. Interference with Transmission of Innate Forces | There can be interference with the transmission of Innate forces. |
| 30. The Causes of Dis-ease | Interference with the transmission of Innate forces causes incoordination of dis-ease. |
| 31. Subluxations | Interference with transmission in the body is always directly or indirectly due to subluxations in the spinal column. |
| 32. The Principle of Coordination | Coordination is the principle of harmonious action of all the parts of an organism, in fulfilling their offices and purposes. |
| No. 33. The Law of Demand and Supply | The Law of Demand and Supply is existent in the body in its ideal state; wherein the “clearing house,” is the brain, Innate the virtuous “banker,” brain cells “clerks,” and nerve cells “messengers.” |
