As objectives become more focused they will become similar in their methods. After all, aren’t we trying to find the best way to accomplish our objective? That is why much of the chiropractic profession wants to appropriate medicine (using chiropractic to address disease). Their objectives are the same. The only problem is that some are not able to give up their traditions in achieving that objective.
Methods should always and usually do, move toward improvement. That is why medicine and its therapies are appropriating “chiropractic”. (using chiropractic adjustments/methods to address disease) and chiropractors want to use drugs. (The discrete use of drugs along with chiropractic would be an improvement in addressing disease.) The $64 question: Where does that leave traditional chiropractic? Is it a difference of objectives or just methods?
