I feel like I am very very set in my beliefs about freedom. I think we ALWAYS have choices for everything we do. True, there are gatekeepers who may prevent us from carrying out certain choices but the fact of the matter is the choices are THERE. Our freedom may sometimes be limited or restricted (such as a man behind bars)... but in general, humanity exists with free will. It is inherent to how we function in life. 

Maybe I don't fully understand functionalism, but so far I think I have to agree with it. If my MARS identity has a brain that carries out the same functions my EARTH identity's brain did... that doesn't mean it's the same brain. That is, not unless the teletransporter has stored my memories, personality trains, thoughts, beliefs, etc. What do you think?
