When is it time to start a new Martial Art?
I don’t know the answer to that question.
Hopefully in writing this, I come to some clarity on this issue.
A new Martial Art cannot be defined only by techniques
No effective Martial Arts has an entirely unique set of techniques.
As far as grappling arts go, there are many common techniques shared across the spectrum of arts.
A new Martial Art cannot be solely defined by its aim. If that were the case, there would be only one grappling art, one striking art, and one submitting art.
Perhaps a new Martial Art is more defined by its rules. What is allowed and what is not allowed has to shape what is included and what is excluded from the art.
The easiest answer of what defines a Martial Art may be who created or codified the Martial Art: Kano’s Judo, Gracie’s Brazilian Jiu-Jitsu, or Oyama’s Kyokushin.
My guess is that what really defines a Martial Art is its philosophy. There would be no Aikido, no JKD, no SPEAR without the philosophy behind (and now science) it.
It could be a combination of all these elements mentioned and others unmentioned that necessitate the start of a new Martial Arts. Is “Going With” and “Stopping?” enough to merit a new Martial Art? I think so. What about you?
