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.
In conventional agriculture, vegetation is kept at the weed or herb level using energy to keep it cut, weeded, tilled, fetilised, and even burnt; that is, we are constantly setting the system back and incurring work and energy-costs when we stop natural succession from occurring.
Instead of fighting this process, we can direct and accelerate it to build our own climax species in a shorter time.
