I think that the ending of the book helps to illuminate one of Orwell's fundamental themes. The implication in the ending is that those in the position of political power will always act in a manner that consolidates their own political power and their own sense of control. The ending of the book is one in which the animals and the humans are fundamentally no different. This represents itself in a physical manner, in terms of the animals not being able distinguish between both. At the same time, the political leanings of the pigs also resembles the humans in that both seek to control the animals, deny their sense of voice, and create a hierarchy where power and autonomy rests with those in the position of political control. The ending of the book represents a real- life setting where politics is not idealized nor is it a reflection of what can be. Rather, it is a blunt statement of what is and how difficult real, authentic, and transparent political change can be. The ending of the book is a real life one, one in which the animals recognize that their own sense of political autonomy is blunted by the fact that the pigs, like the humans, control each aspect of their state of being.
