He is less straightforward than most characters in the novel, and a number of interpretations have been put forward to which social class he represents as regards to the Russian Revolution and the Soviet Union.
He does not use his ability for the benefit of others until the end of the book when Boxer is sent off to the slaughterhouse, and when Clover asks him to read the public display of the Seven Commandments, as they, for the last time in the book, changed; Benjamin reveals that the Commandments now consist entirely of the message "All animals are equal, but some animals are more equal than others".
He is also quite significant in that he is not quite a horse (the working class) and yet definitely not a leader like the pigs, although his intellect is at least equal to theirs, this implies that Benjamin is a symbol of the intelligentsia who during the revolution and its aftermath are very much aware of what is going on, but do nothing about it.
Although he is aware of their mistreatment (especially that of Boxer) and can see how the basic rules of their society are changing, he is unwilling to act on it in any way that would threaten his security.
Orwell became known as "Donkey George" to his friends – a reference to both his gloomy disposition and the character of Benjamin.
