Final answer:
The pigs in 'Animal Farm' allow Moses to return and feed him because his tales of Sugarcandy Mountain serve to subdue the other animals, thereby helping the pigs maintain control and power.
Step-by-step explanation:
In Animal Farm by George Orwell, the pigs allow Moses the raven to return and even provide him with food although they don't believe in the paradise of Sugarcandy Mountain that he preaches about. This is because Moses, with his tales, serves the purpose of distracting the other animals from the harsh reality of their lives under the pigs' rule. The promise of a better life after death keeps them subdued and less likely to rebel against the current regime.
By providing Moses with sustenance, the pigs ensure he continues to spread these beliefs, which in turn works to maintain the social order on the farm. It is a strategic move by the pigs to retain power and control over the other animals. The allowance of Moses's return illustrates the manipulative nature of the pigs and their use of ideology to manage and manipulate the animal populace.
