One more issue involving the title I don't think was mentioned. MONEY.
I'm good at what I do, pay me! Not only that but I'm the only master around.. pay me more. I have certificates
Well, that is one of the advantages of being a Master Craftsman. Master Electricians demand (and receive) more compensation than Apprentice Electricians.
The problem with applying it to martial arts is that, even when there are objective standards for skill and knowledge, they apply
only within that specific branch of that specific martial art. As I wrote regarding Black Belt certifications, what one art's certifying body considers "Master" should be irrelevant to another art, and the more different they are, the less relevant it should be. A Shotokan certifying body has no authority to judge a Tae Kwon Do student's rank, but we might reasonably believe they could have some insight due to strong similarities between the styles. On the other hand, the same Shotokan certifying body has far less insight, but still some, for Boxe Francaise. Finally, one would expect said Shotokan certifying body to have almost no insight on the certifications for Catch as Catch Can wrestling.
In short, while I may be offended by (and grouse about) some organization that certifies a 15 year old kid as a "Master" after studying for 3 years, it's really not my business to judge it (although I admit, being human, I probably will).
There's only four things to do about it.
First, we could have a Universal Certifying Body which all martial arts must submit to. Can you see this ever happening? Me neither? Nor do I think it's a "good idea." It's a horrible idea.
Second, we could do it the way they did it in the old days. If someone pops up claiming to be a "Master" the local Guild representative would send someone (or several) out to "examine" him. Alternately, some other Master would spontaneously decide to go test 'em out. People died.
Third, we could just accept that, barring the two previous options, different organizations are going to decide whatever they want. Live and let live. Yeah, I don't see this happening either. Just goes against human nature.
Finally, we can continue to gripe about it, debating with friends and various interested communities what constitutes as "Master." But, ultimately, acknowledging we are powerless to address the "issue." Yeah, that sounds like what we'll end up continuing to do. Sucks, but at least no one gets killed in challenge matches.
Peace favor your sword,
