Chiropractic purpose
Tone
A central word in D.D. Palmer’s explanation of chiropractic.
The big idea
D.D. places tone at the foundation of chiropractic and connects the surrounding discussion with functions performed with normal vigor. A first reading should keep that wider functional context in view instead of treating tone as only a word about tight muscles.
An everyday illustration
A well-tuned instrument offers an everyday image of condition and function fitting together. It is a reading aid, not a model of a nerve.
An original illustration to help explain the idea, not a quotation or evidence of a biological mechanism.
In the author’s words
“Chiropractic as a science is founded on tone. Its philosophy deals with the knowledge of biological phenomena, that state of a body, or any of its organs or parts, in which the animal and organic functions are performed with normal vigor.”

Read it in context
D.D.’s wording centers tone. Stephenson’s later principles explicitly define coordination. These passages show different emphases; they do not establish that the two words are identical.
