* "Man is the only creature that consumes without producing." This is a direct metaphor comparing humans to parasites who take from animals without giving anything back.
* "All men are enemies. All animals are comrades." This is a powerful metaphor that sets up the core ideology of the revolution. It creates a clear dichotomy between humans and animals.
* "The life of an animal is misery and slavery: that is the plain truth." This is a metaphor for the harsh realities of animal life under human control. "Misery and slavery" are not literal descriptions, but evoke the feelings of oppression and hardship.
* "No animal has ever seen a field of oats or a pile of turnips that he could not eat." This statement, while not a traditional metaphor, uses the image of food as a symbol of freedom and abundance, contrasting with the scarcity and deprivation of animal life under human rule.
