Trembling Colors

“Random chance was not a sufficient explanation of the Universe---in fact, random chance was not sufficient to explain random chance; the pot could not hold itself.”
― Robert A. Heinlein, Stranger in a Strange Land

“You have to have been out on a long patrol to appreciate this properly. You need to have looked forward to your day of guard duty, for the privilege of standing two hours out of each six with your spine against bulkhead thirty and your ears cocked for just the sound of a female voice. I suppose it's actually easier in the all-stag ships... but I'll take the Rodger Young. It's good to know that the ultimate reason you are fighting actually exists and that they are not just a figment of the imagination.”
― Robert A. Heinlein, Starship Troopers

“The bugs are not like us. The Pseudo-Arachnids aren’t even like spiders. They are arthropods who happen to look like a madman’s conception of a giant intelligent spider, but their organization, psychological and economic, is more like that of ants or termites; they are communal entities, the ultimate dictatorship of the hive.”
― Robert A. Heinlein, Starship Troopers

“There are a dozen different ways of delivering destruction in impersonal wholesale, via ships and missiles of one sort or another, catastrophes so widespread, so unselective, that the war is over because that nation or planet has ceased to exist. What we do is entirely different. We make war as personal as a punch in the nose. We can be selective, applying precisely the required amount of pressure at the specified point at a designated time . . . .
We are the boys who go to a particular place, at H-hour, occupy a designated terrain, stand on it, dig the enemy out of their holes, force them then and there to surrender or die. We're the bloody infantry, the doughboy, the duckfoot, the foot soldier who goes where the enemy is and takes him on in person. We've been doing it, with changes in weapons but very little change in our trade, at least since the time five thousand years ago when the foot sloggers of Sargon the Great forced the Sumerians to cry "Uncle!"
Maybe they'll be able to do without us someday. Maybe some mad enius with myopia, a bulging forehead, and a cybernetic mind will devise a weapon that can go down a hole, pick out the opposition, adn force it to surrender or die--without killing that gang of your own people they've got imprisoned down there. I wouldn't know; I'm not a genius, I'm an M.I. In the meantime, until they build a machine to replace us, my mates can handle that job--and I might be some help on it, too.”
