Population pressure works much like a rising river. You can put up dikes or levees, but the day comes when the river has to go somewhere. - Robert A. Heinlein

“You put me in mind of a case I ran into in the American West. A respected citizen shot a professional gunthrower in the back. When asked why he didn’t give the other chap a chance to draw, the survivor said, ‘Well, he’s dead and I’m alive and that’s how I wanted it to be.’ Jamie, if you use sportsmanship on a known scamp, you put yourself at a terrible disadvantage.”

You aren't really there at all. There isn't anybody but me — Jane — here alone in the dark. I miss you dreadfully!

What is a “concrete” word? It is a spell-symbol used to tag something you can point to and thereby agree on, e. g., “cat,” “sailboat,” “ice-skating”—agree with such certainty that when you say “sailboat’’ there is no chance whatever that I will think you mean a furry quadruped with retractile claws.
With the spell symbol “God” there is no way to achieve such agreement because there is nothing to point to.
