The last chapter to Orwell's work is quite effective in bringing out the themes that drive it. The full evolution of how power can be abused by anyone who possesses it is evident. The manner in which the pigs end up consolidating their power and replicate the abuse of control is demonstrative of Orwell's fundamental thesis. In this, politics and political orders are seen as a force that seeks to control and dominate. The last chapter brings this out in how Napoleon changes the farm, including the manner in which the animals interact with one another, the flag of the farm, and even the name, reverting back to the Jones' "Manor Farm." The animals, peering through the glass, cannot tell the difference between the pigs and the humans. It is here where Orwell makes it very clear that the diligence and vigilance of citizens are both needed to ensure that those who rule over individuals do not lose touch with those individuals' need. I think that the last chapter is quite effective in bringing this out and making clear that political orders must be held responsive to its citizens or their rights will face an inevitable violation.
