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.
Handmade washi (traditional Japanese paper) is replete with appeal. Looking at it, touching it, fills me with an indescribable sense of satisfaction. The more beautiful it is, however, the more difficult it is to put to use. Only a master of calligraphy could possibly add to its beauty; it is exquisite just as it is. This is wonderfully strange, for it is merely a simple material. Yet plain and undecorated as it is, it is alive with nuanced beauty. Good washi makes possible our most ambitious creative dreams.
One can gain a glimpse of the quality of a people’s life by the kind of paper they use for writing letters, for literary works, and for various other tasks. Paper should not be deprecated. To do so is to deprecate beauty itself.
