BTW, note how Ueshiba knew enough to relate these skills to already-existing classics. Should we say that he was slighting Takeda by doing so or should we say that Ueshiba understood that these skills were not new and that they have been around a long time.... and he was just acknowledging the obvious, no slight intended? To put it another way, Ueshiba would have looked ill-informed if he'd actually said that Takeda originated "Aiki". Ueshiba knew better.
Hm, I think that describes Ueshiba's behavior pretty well. It may have been a factor (the major factor?) in his severing ties/"moving on" from Takeda. Why credit him if Takeda didn't even understand the full context?
On the other hand, it seems like it would have been fair to say Takeda showed/taught him aiki, since Ueshiba failed to learn it on his own. Thus there is a legitimate debt there.
