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.
For Alfred North Whitehead, a car accident and the exposure of a pyramid to the sun on any given day are equivalent events:
We are accustomed to associate an event with a certain melodramatic quality. If a man is run over that is an event comprised within certain spatio-temporal limits. We are not accustomed to consider the endurance of the Great Pyramid throughout any definite day as an event. But the natural fact which is the Great Pyramid throughout a day, meaning thereby all nature within it, is an event of the same character as the man's accident, meaning thereby all nature with spatio-temporal limitations so as to include the man and the motor during the period when they were in contact.
Apparently architecture does the same job as set design, "it creates units of environment, atmosphere, or events"—whatever you wish to call them—but with more weight, carrying more material, slower. This is why it can raise the curtain more times and repeat "there it is again" for longer. Perhaps for this and other reasons there are periods in the history of architecture in which stage design or the folly, for example, have been an effective field of experimentation for serious architects.
When a client arrives at my studio, my job consists of preparing a "stage" for the length of time he desires, whether it be for a day or years, it is irrelevant in the end. A stage in which he can move under the sun "as if he were at home," though he walks stuttering at first before learning what will come in the script, be it kind or not, and which he will repeat a thousand times until he tires. When he tires, a panel is disassembled to readapt the children's room, the roof is demolished to make a study, the façades are decorated and life continues unperturbed.
