Thank you for answering my question.
I don't see this global cange when looking at what we can know about the history of aikido.
And I don't "experience" it when practicing with my teacher who has practiced with the late Sugino Yoshio (besides other teachers).
So I don't agree with your statement. Be it sitting over my books or be it practicing on the tatami.
I myself think that the assumption of a global change after WWII just makes it easier for us, to - seemingly! - understand what Ueshiba thaught and did.
Thank you too for responding in clear way.
Herein lies the core of the differences of opinion within Aikido. Herein in my opinion lies the reason that Aikido potentially is different to other martial arts. Herein lies the difference between Ueshibas personal ability and others.
Not trying to convince you but merely stating where I come from.
