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.
Photos of the Tanikawa House, designed by architect Kazuo Shinohara.
Built in 1974, this summer house materializes the act of covering a piece of earth, making it an inhabitation only by means of a roof protecting the dirt soil of the ground. The house lies on a slope in a middle of a wood and grows through an exposed timber frame structure which supports a large pitched roof. Under the roof, a minimal section of the house located on a side hosts some specific living functions concentrated on two floors: a bathroom, a kitchen, a bedroom and a staircase. This section lies in parallel to the main “earth room” (or “summer room”) and overlooks it.
