“Man is the only real enemy we have”
Context: Old Major addresses the animals in the barn, identifying the source of all their suffering.
Analysis
The absolute noun "only" frames Man as the single root of oppression, creating the simple, binary worldview on which the Rebellion is built. Old Major's rhetoric unites a diverse group of animals against a common enemy, mirroring how Marxist theory rallied the working class. The irony Orwell plants here is that the pigs will later become the very enemy Old Major warns against.

Exam Tip
Use for the origins of revolutionary ideology. Track how "Man" as the enemy is later replaced by the pigs themselves — the abuse continues under new masters.
