I had one question after last friday's class on freedom.  We heard the argument that we do not have physical freedom because our actions are merely based on what causes them.  Thus, our lives are merely the effects we act out based on the causes from the environment.  My question was if this simplification of life would be detrimental to this argument, in that one of anything does not exist in nature.  I think we talked about this when we discussed trying out one's new sword.  If you break down an atom, there are sub atomic particles.  So if this idea holds true, would that counter attack professor Vaught's argument on physical freedom?  Having one action being caused by one external stimulus from our environment?
