In Animal Farm, which of all animals seem to represent the point of view of the author?

I would say that Boxer probably best represents Orwell's point
of view.  I think that this is something that is brought out for a variety of reasons.  The first
is that Orwell's story ends on such a cynical note in that freedom and autonomy are not
recognized through the government.  Collective happiness is not something that is seen through
Napoleon's reign.  In the end, when the other animals cannot recognize the difference between the
humans and the pigs, it helps to bring out the fact that there is an overwhelming lack of faith
in the governmental structure.  With this in mind, I would say that Boxer becomes the ultimate
representation of how Orwell views individuals and their relationship with government.  Boxer has
blind faith in the authority structure.  Never questioning any of its ulterior motives and never
raising any voice of dissent, Boxer continues to "work harder" and do more.  In the end, after
giving everything he has to the machine of government, he is crushed by the weight of that
machine and conveniently "forgotten" so that others can continue to become the grist for
government.  This sad and cynical read is something that Orwell, himself, believed in towards the
end of his life and in the belief that human freedom and expression was not being properly
channelled in both the Communist world and the supposed "liberalized"
West.
