Sometime ago I did an article about Heinlein for a blog (not this one) and tried to boil down the influence Heinlein had on me.
Because I was feeling less than sanguine about it–and also had more time than for this blogging, not being, then, pressed with deadlines–I not only gave it to friends to do first reading on, but I sent it to one of my publishers, Toni Weisskopf at Baen, to look over (a necessity since I’m capable of untold cruelty to the common comma, have an ongoing war with double letters and have written many a disreputable apostrophe–all of which immediately become invisible upon the paper, of course).
I’d made some general pronouncement about what Heinlein believed, and Toni rapped me on the knuckles with the editorial ruler and pointed out that in his long and varied life, Heinlein believed practically everything at one time or another.
She was right. Having read all his works one time or a hundred, I came to the conclusion that you can find in Heinlein anything you want to find.
