The Dispossessed (Hainish Cycle, #6)

by Ursula K. Le Guin

“But it’s true, chronosophy does involve ethics. Because our sense of time involves our ability to separate cause and effect, means and end. The baby, again, the animal, they don’t see the difference between what they do now and what will happen because of it. They can’t make a pulley, or a promise. We can. Seeing the difference between now and not now, we can make the connection. And there morality enters in. Responsibility. To say that a good end will follow from a bad means is just like saying that if I pull a rope on this pulley it will lift the weight on that one. To break a promise is to deny the reality of the past; therefore it is to deny the hope of a real future. If time and reason are functions of each other, if we are creatures of time, then we had better know it, and try to make the best of it. To act responsibly.”
