Watership Down (1972)

• Many human beings say that they enjoy the winter, but what they really enjoy is feeling proof against it. For them there is no winter food problem. They have fires and warm clothes. The winter cannot hurt them and therefore increases their sense of cleverness and security. For birds and animals, as for poor men, winter is another matter. Rabbits, like most wild animals, suffer hardship.

• All the world will be your enemy, Prince with a Thousand Enemies. And whenever they catch you, they will kill you. But first, they must catch you; digger, listener, runner, Prince with the swift warning. Be cunning, and full of tricks, and your people will never be destroyed.

• Look. Look. That's the place for us. High, lonely hills, where the wind and the sound carry, and the ground's as dry as straw in a barn. That's where we ought to be. That's where we have to get to.

• Dangerous thing, a name. Someone might catch hold of you by it, mightn't they?

• When the man was disgraced and told to go away, he was allowed to ask all the animals whether any of them would come with him and share his fortunes and his life. There were only two who agreed to come entirely of their own accord, and they were the dog and the cat. And ever since then, those two have been jealous of each other, and each is for ever trying to make man choose which one he likes best. Every man prefers one or the other.

• I dislike the whole business of experiments on animals, unless there's some very good and altogether exceptional reason in a particular case. The thing that gets me is that it's not possible for the animals to understand why they're being called upon to suffer. They don't suffer for their own good or benefit at all, and I often wonder how far it's for anyone's. They're given no choice, and there's no central authority responsible for deciding whether what's done in this case or that is morally justifiable. These experimental animals are just sentient objects; they're useful because they're able to react; sometimes precisely because they're able to feel fear and pain. And they're used as if they were electric light bulbs or boots. What it comes to is that whereas there used to be human and animal slaves, now there are just animal slaves. They have no legal rights, and no choice in the matter.
