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 recognize this is a very niche endeavor, but the art and craft of maintaining a homepage, with some of your writing and a page that's about you and whatever else over time, of course always includes addition and deletion, just like a garden — you're snipping the dead blooms. I do this a lot. I'll see something really old on my site, and I go, “you know what, I don't like this anymore,” and I will delete it.
But that's care. Both adding things and deleting things. Basically the sense of looking at something and saying, “is this good? Is this right? Can I make it better? What does this need right now?” Those are all expressions of care. And I think both the relentless abandonment of stuff that doesn't have a billion users by tech companies, and the relentless accretion of garbage on the blockchain, I think they're both kind of the antithesis, honestly, of care.
