I've been reading Expanded Universe, and I was amazed to realize that I had not read it before. I found it most interesting for the stunning prophetic things discussed in pre-1980 essays that directly address the current situation. It got me to thinking that I'd like to start a series of short posts called "Wisdom of Heinlein".
Here's the first: "Liberals are people who know that water flows down hill, but think it will never reach the bottom."
(That pretty much describes every policy agenda of the current US administration.)
