I have no experience of children’s school sports so I cannot understand the comparison, but I’ve seen dojo teachers treated like feudal lords!I agree with you here. Japanese culture has no problem having two or three belief systems side by side, utilizing whatever aspect of them that fits the situation. I had a Shinto wedding there, which is common, but funerals are usually done in Buddhist fashion. Even Christianity existed alongside these other belief systems.
I think this is stretching things too far. The same argument can be said of a high school football team being the "family" and the coach being the "father." Teams have their own unique little rituals as well. I doubt if any member of a high school football team (including coaches) has a good idea of who Confucius even was, excepting maybe knowing the "Golden Rule" ascribed to him. So, I think this argument falls short, IMO.
While I stated that Confucianism penetrated Japanese culture, in varying degrees depending on class, that does not mean it had any influence on its martial art technical aspects. Perhaps it did encourage a "dojo behavior," but that could also be a case of parallel evolution as in my football example.
Some in MA self-defense do, however, follow a variation of the Golden Rule - "Do unto others before they do unto you," but that's as close to Confucious as they get
But the point is that Confucius didn’t invent these ideas so much as defined and characterised them since he suggested the principles of being a ‘superior man’ with high moral standards and ‘goodness’ are inherent and simply require extracting. This nurturing process included ritual (defined behaviours for a given situation…etiquette, if you will…sounds a bit like reiho, eh?), respecting one’s elders, parents, superiors (sounds like the way we’d treat sensei/some etc). These seniors should display the highest moral standards and thus lead by example: they were respected and followed because they were admired for their model behaviour rather than blindly followed because they were merely older etc. Benevolence (the way we should treat beginners) etc. Transgressions of correct behaviour required punishment but Confucius advocated the use of the absolute minimum disciplining to produce the desired correction….
It all fits so well with what I observe in the world of (proper) martial arts!
