You should set concrete goal and language to coordinate the actions of the many
Concrete language helps people, especially novices, understand new concepts. Abstraction is the luxury of the expert. If you've got to teach an idea to a room full of people, and you aren't certain what they know, concreteness is the only safe language. (…) When Boeing prepared to hunch the design of the 727 passenger plane in the 1960s, its managers set a goal that was deliberately concrete: The 727 must seat 131 passengers,1 fly nonstop from Miami to New York City, and land on Runway 4-22 at La Guardia. (The 4-22 runway was chosen for its length—less than a mile, which was much too short for any of the existing passenger jets.) With a goal this concrete, Boeing effectively coordinated the actions of thousands of experts in various aspects of engineering or manufacturing. Imagine how much harder it would have been to build a 727 whose goal was to be "the best passenger plane in the world".
Yet, certainly, the wise learn many things from their enemies; for caution preserves all things. From a friend you could not learn this, but your foe immediately obliges you to learn it. For example, the states have learned from enemies, and not from friends, to build lofty walls, and to possess ships of war. And this lesson preserves children, house, and possessions.
The present theory then must be considered to be a suggested program or framework for future research and must stand ...
It’s saying no.
That’s your first hint that something’s alive. It says no. That’s how you know a baby is starting to turn into a person. They run around saying no all day, throwing their aliveness at everything to see what it’ll stick to. You can’t say no if you don’t have desires and opinions and wants of your own. You wouldn’t even want to.
No is the heart of thinking.
