“Aurelia, not all those women are uppity aristocratic bitches. Most of them are normal nice girls trying to survive in shark-infested waters, so if you want to make a difference, why not go in there and change the way things work?" "How?" Marcus smiled deviously. "By unseating the queen bee and changing the rules." "That sounds like a great idea, Colonel. Lead me to the beehive.”

“Let’s say you have an ax. Just a cheap one, from Home Depot. On one bitter winter day, you use said ax to behead a man. Don’t worry, the man was already dead. Or maybe you should worry, because you’re the one who shot him. He had been a big, twitchy guy with veiny skin stretched over swollen biceps, a tattoo of a swastika on his tongue. Teeth filed into razor-sharp fangs-you know the type. And you’re chopping off his head because, even with eight bullet holes in him, you’re pretty sure he’s about to spring back to his feet and eat the look of terror right off your face. On the follow-through of the last swing, though, the handle of the ax snaps in a spray of splinters. You now have a broken ax. So, after a long night of looking for a place to dump the man and his head, you take a trip into town with your ax. You go to the hardware store, explaining away the dark reddish stains on the broken handle as barbecue sauce. You walk out with a brand-new handle for your ax. The repaired ax sits undisturbed in your garage until the spring when, on one rainy morning, you find in your kitchen a creature that appears to be a foot-long slug with a bulging egg sac on its tail. Its jaws bite one of your forks in half with what seems like very little effort. You grab your trusty ax and chop the thing into several pieces. On the last blow, however, the ax strikes a metal leg of the overturned kitchen table and chips out a notch right in the middle of the blade. Of course, a chipped head means yet another trip to the hardware store. They sell you a brand-new head for your ax. As soon as you get home, you meet the reanimated body of the guy you beheaded earlier. He’s also got a new head, stitched on with what looks like plastic weed-trimmer line, and it’s wearing that unique expression of “you’re the man who killed me last winter” resentment that one so rarely encounters in everyday life. You brandish your ax. The guy takes a long look at the weapon with his squishy, rotting eyes and in a gargly voice he screams, “That’s the same ax that beheaded me!” IS HE RIGHT?”

“From a philosophical point of view, Leibniz's most interesting argument was that absolute space conflicted with what he called the principle of the identity of indiscernibles (PII). PII says that if two objects are indiscernible, then they are identical, i.e. they are really one and the same object. What does it mean to call two objects indiscernible? It means that no difference at all can be found between them--they have exactly the same attributes. So if PII is true, then any two genuinely distinct objects must differ in at least one of their attributes--otherwise they would be one, not two. PII is intuitively quite compelling. It certainly is not easy to find an example of two distinct objects that share all their attributes. Even two mass-produced factory goods will normally differ in innumerable ways, even if the differences cannot be detected with the naked eye. Leibniz asks us to imagine two different universes, both containing exactly the same objects. In Universe One, each object occupies a particular location in absolute space.In Universe Two, each object has been shifted to a different location in absolute space, two miles to the east (for example). There would be no way of telling these two universes apart. For we cannot observe the position of an object in absolute space, as Newton himself admitted. All we can observe are the positions of objects relative to each other, and these would remain unchanged--for all objects are shifted by the same amount. No observations or experiments could ever reveal whether we lived in universe One or Two.”

“These bizarre examples attempt to prove one conceptual point or another by deliberately reducing all but one underappreciated feature of some phenomenon to zero, so that what really counts can shine through. The twin earth example sets internal similarity to a maximum (you are whisked off to Twin Earth without being given a chance to register this huge shift) so that external context can be demonstrated to be responsible for whatever our intuition tells us.”
