"Who Will Guide Us...?"

In a comment on the last post, AF1 made a comment that gets to the core of what I see as a major problem. AF1, this isn't aimed at you, but aimed at an attitude that I see throughout the martial arts world.

That gym is famous for banging it out. In fact if I'm not mistaken it was them who first coined the phrase "alive training."

So if they say it really works, and you say it doesn't work, who are we to believe? Is it possible that there is more than one way to skin a cat?
The point is not whether to believe me or to believe them. Either way, it is an "argument from authority," one of the classical logical fallacies. (Especially annoying, if I am the authority in question.) All it means, whichever you decide, is who you have chosen to do your thinking for you. It has nothing to do with being right.
That's getting really close to the essence of one of the things that has been bothering me. Martial arts, self-defense, whatever label you put on this endeavor is supposed to make you better. Stronger, fitter, and, in my mind at least, smarter and tougher and more independent as well.
That means thinking for yourself. Observing for yourself. And sometimes challenging ideas from people you respect.
So if you want someone to do your thinking for you, go with the other guy. You've already missed the point of everything I have to say. There are lots of people out there actively looking for acolytes and yes-men who will welcome you with open arms.
And, to be glib, when we are talking about knife defense, it's more accurate to say that there is more than one way to fail to skin a cat.
