I feel like freedom has been mostly an illusion of it than a real thing as such. However I would like to recall something from George Owen's 1984, where one of the characters tallked about the fact no matter how oppressed we really are from our governments and how little we can do from that oppression, our minds will be a place for us to do anything, to imagine anything we want... until we lose our humanity.
Having values, loving, caring, feeling, reasoning, are all attributes of a human, and as long as we carry them with us, we will always be, in a way, free.
However, that's not a reason enough to let others control our actions.
