“Hit it! You have to hit it harder than that. Electrons are timid little things but notional; you have to let them know who’s boss.”

“Consider the black widow spider. It's a timid little beastie, useful and, for my taste, the prettiest of the arachnids, with its shiny, patent-leather finish and its red hourglass trademark. But the poor thing has the fatal misfortune of possessing enormously too much power for its size. So everybody kills it on sight.”

“You can have peace. Or you can have freedom. Don't ever count on having both at once.”

“Have you ever known me to be rude to a lady?" "I have seen you be intentionally rude to a woman. I have never seen you be rude to a lady.”

“There is a misconception, geocentric and anthropomorphic, common to the large majority the the earthbound, which causes them to visualize a planetary system stereoscopically. The mind's eye sees a sun, remote from a backdrop of stars, and surrounded by spinning apples -- the planets. Step out on your balcony and look. Can you tell the planets from the stars? Venus you may pick out with ease, but could you tell it from Canopus, if you had not previously been introduced? That little red speck -- is it Mars, or is it Antares? Blast for Antares, believing it to be a planet, and you will never live to have grandchildren.”

“Let's skip [Mobile Infantry] tradition for a moment. Can you think of anything sillier than being fired out of a spaceship with nothing but mayhem and sudden death at the other end? However, if someone must do this idiotic stunt, do you know a surer way to keep a man keyed up to the point where he is willing than by keeping him constantly reminded that the only good reason why men fight is a living, breathing reality?"In a mixed ship [men and women] the last thing a trooper hears before a drop (maybe the last word he ever hears) is a woman's voice, wishing him luck. If you don't think this is important you've probably resigned from the human race.”

“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.”
