Ah, my friend, I wondered the same thing. I thought it was pretty obvious too, and there really wasn't any argument against it, but it seems the length has come more from misunderstanding (thinking the concept was equal to "know the history or you can't perform the techniques", which it never was, or "knowing the history means you need to be approaching it like a scholar or academic", which, again, was never the case). I'm not sure that this is what JKS had in mind when he split my post and the others to start this thread, though. I get the feeling that he was intending more for a discussion of "the history of my art says x, so we do y", kind of like the brief discussion on stance and terrain a page or so ago. But these threads do have a life of their own, and there was a lot of confusion as to the role of Koryu in the discussion, so that kinda pushed it one way as well. That said, the stance/terrain conversation could start this thread going in another, related direction. That could be interesting. Oh, and that's precisely what I meant in regards to the BJJ as well. No confusion needed.
