Philip Pullman makes a strong point about authority 'brain washing' our minds into thinking what is right and wrong. Right now, in the mind of the human being, certain thoughts are not thought, even though it completely free to do so. The mind can begin to function like an actual member of society, so you impose society's rules on your own thoughts, allowing society to control your mind. Maybe the great war at the end is a symbolic fight for free will. How much of what we think is imposed by society? Everything is most likely effected in some way or another. It would be impossible to eliminate the social influence on our thinking, but maybe it is a good idea to think now and then about how much of our thought is socially influenced. It might give us an idea of how much free will we actually possess, maybe a good thing to know.
