The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.
The McNamara fallacy, named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.
The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.
There is a Japanese catchphrase, community suru, literally "making" or "doing" community. I will never forget the queasy feeling that came over me when I first heard that term, phrased as if community were a kind of event.
Hold an event, bring people together, get people who might otherwise never meet to interact. It's a wonderful thought. I have nothing against events per se. However, if they are not spontaneous and voluntary, they will not last. That is my objection to the keep-it-lively concept of community. The perception of community as event stems, I think, from a yearning for the festivals and rituals that once flourished in rural communities in Japan. But those events occurred precisely because a community existed, not the other way around.
