Animal Farm is a satirical novella (which can also be understood as a modern fable or allegory) by George Orwell, ostensibly about a group of animals who oust the humans from the farm on which they live. They run the farm themselves, only to have it degenerate into a brutal tyranny of its own.

Chapter 1

• Man is the only real enemy we have. Remove Man from the scene, and the root cause of hunger and overwork is abolished forever. Man is the only creature that consumes without producing. He does not give milk, he does not lay eggs, he is too weak to pull the plough, he cannot run fast enough to catch rabbits. Yet he is lord of all the animals. He sets them to work, he gives back to them the bare minimum that will prevent them from starving, and the rest he keeps for himself.
• Why then do we continue in this miserable condition? Because nearly the whole of the produce of our labour is stolen from us by human beings.
• Remember, comrades, your resolution must never falter. No argument must lead you astray. Never listen when they tell you that Man and the animals have a common interest, that the prosperity of the one is the prosperity of the others. It is all lies. Man serves the interests of no creature except himself. And among us animals let there be perfect unity, perfect comradeship in the struggle. All men are enemies. All animals are comrades.
• The vote was taken at once, and it was agreed by an overwhelming majority that rats were comrades. There were only four dissentients, the three dogs and the cat, who was afterwards discovered to have voted on both sides.

Chapter 2

THE [ORIGINAL] SEVEN COMMANDMENTS:

1. Whatever goes upon two legs is an enemy.
2. Whatever goes upon four legs, or has wings, is a friend.
3. No animal shall wear clothes.
4. No animal shall sleep in a bed.
5. No animal shall drink alcohol.
6. No animal shall kill any other animal.
7. All animals are created equal.

Chapter 3

• Nobody stole, nobody grumbled over his rations, the quarreling and biting and jealousy which had been normal features of life in the old days had almost disappeared.
• Old Benjamin, the donkey, seemed quite unchanged since the Rebellion. He did his work in the same slow obstinate way as he had done it in Jones's time, never shirking and never volunteering for extra work either. About the Rebellion and its results he would express no opinion. When asked whether he was not happier now that Jones was gone, he would say only "Donkeys live a long time. None of you has ever seen a dead donkey," and the others had to be content with this cryptic answer.
• Four legs good, two legs bad.
• Squealer: "Comrades!" he cried. "You do not imagine, I hope, that we pigs are doing this in a spirit of selfishness and privilege? Many of us actually dislike milk and apples. I dislike them myself. Our sole object in taking these things is to preserve our health. Milk and apples (this has been proved by Science, comrades) contain substances absolutely necessary to the well-being of a pig. We pigs are brainworkers. The whole management and organization of this farm depend on us. Day and night we are watching over your welfare. It is for your sake that we drink that milk and eat those apples."
• Surely, comrades, surely there is no one among you who wants to see Jones come back?
• Now if there was one thing that the animals were completely certain of, it was that they did not want Jones back. When it was put to them in this light, they had no more to say. The importance of keeping the pigs in good health was all too obvious. So it was agreed without further argument that the milk and the windfall apples (and also the main crop of apples when they ripened) should be reserved for the pigs alone.

Chapter 5

• Until now the animals had been about equally divided in their sympathies, but in a moment Snowball’s eloquence had carried them away.
• Squealer: Do not imagine, comrades, that leadership is a pleasure. On the contrary, it is a deep and heavy responsibility. No one believes more firmly than Comrade Napoleon that all animals are equal. He would be only too happy to let you make your decisions for yourselves. But sometimes you might make the wrong decisions, comrades, and then where should we be?

Chapter 6

• Once again the animals were conscious of a vague uneasiness. Never to have any dealings with human beings, never to engage in trade, never to make use of money— had not these been among the earliest resolutions passed at the first triumphant Meeting when Jones was expelled?
• Napoleon: Comrades, do you know who is responsible for this? Do you know the enemy who has come in the night and overthrown our windmill? SNOWBALL!

Chapter 7

• "Ah, that is different!" said Boxer. "If Comrade Napoleon says it, it must be right."
• Animal Farm, Animal Farm,
  Never through me shalt thou come to harm!

Chapter 8

• But when Muriel reads the writing on the barn wall to Clover, interestingly, the words are, "No animal shall kill any other animal without cause."
• At the foot of the end wall of the big barn, where the Seven Commandments were written, there lay a ladder broken in two pieces. Squealer, temporarily stunned, was sprawling beside it, and near at hand there lay a lantern, a paint-brush, and an overturned pot of white paint.
• None of the animals could form any idea as to what this meant, except old Benjamin, who nodded his muzzle with a knowing air, and seemed to understand, but would say nothing.
• Somehow or other, the last two words had slipped out of the animals’ memory. But they saw now that the Commandment had not been violated; for clearly there was good reason for killing the traitors who had leagued themselves with Snowball.

Chapter 10

• Somehow it seemed as though the farm had grown richer without making the animals themselves any richer— except, of course, for the pigs and the dogs.
• Four legs good, two legs better!
• ALL ANIMALS ARE EQUAL
  BUT SOME ANIMALS ARE MORE EQUAL THAN OTHERS.
• The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which.
