I disagree. Just as you wouldn't throw a beginner into the deep end and yell "Now swim!", I don't see why a discussion on baseline skillset should be anything other than baseline principles.
Well, because aikido, specifically, has been mentioned repeatedly and many times the claim has been made that the specific body skills (which have never been specifically named) "are" aiki.
I say I keep my balance and cause the other guy to fall down. That's about as baseline as you can get but the criticism is that I don't explain "how" I do that.
On the other hand, the "explanations" given are not really more precise. So the topic naturally weaves around and I'm not the only one weaving it.
