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.
I am a sucker for stories in which seeds of cosmic revelation are found hidden inside everyday materials, especially when those materials are architectural in form.
In this case, it was “the imprint of a rare solar storm” that left traces in the rings of trees cut into logs by Vikings and used to build cabins 1,000 years ago on the Atlantic coast of Canada.
…While there is obviously more to say about the science behind this discovery—all of which you can read here—what interests me is simply the idea that astral events, cosmic storms, stellar weather, electromagnetic pulses from space, whatever you want to imagine, leave traces all around us. That in the depths of our buildings, in our walls and floors, even in the wooden dowels of mass-produced furniture, there can be evidence of immensely powerful and beautiful things, and I would like to remember to look for that again. It’s been a miserable couple of years.
