Any way, I wouldn't say that aikido is unique in such thoughts. Even Kano sensei has written about the principle of "jita kyoei" (mutual welfare and benefit) for judo. I'm sure that those folks (myself included) who have been on the receiving end of some judo techniques will say that my impact with the earth (oof) sure didn't feel so beneficial to my health! Yet, I can understand how the principle of "jita kyoei" comes through in the actual keiko and the shugyo.
Jita-Kyoei is often taught as a principal part of Judo. This is false.
Jita-kyoei cannot be deduced from the Gokyo-no-waza, shime-waza, kensetsu-waza, and so forth. It is an ethical principal that was smuggled into jacketed wrestling (Judo). To claim that it came from Judo is ridiculous.
I was actually asked to leave one Judo school because when the teacher asked me what I thought Judo was (in front of everyone) I told him, "Judo is jacketed wrestling." The teacher said, "You can't mean that! Tell me that is not what you mean!" I told him, "That is exactly what I mean, and that is exactly what Judo is." The teacher said to me, "But, Beetle, don't you think that Judo can teach people to be better moral people? Don't you think Judo has the potential to bring about world peace?" I tell this nut, "Judo teaches a person how to throw, pin, lock, and strangle another person. These techniques have no bearing on whether I steal a car or pay for it. They neither encourage me to support democracy nor anarchy."
Being a master of Judo does not mean you are a good, peaceful, and moral person. One of the best Judo players I know loves to hang out at strip joints, get drunk, start fights, whip the bouncers when they come to stop the fights, and is often having to be bailed out of jail the next day. He will then go teach his kid's class about how Judo gives the moral strength to do the right thing. He knows that such moral claims attracts more students, and more students mean more money, and more booze, strippers, .....
