If a man is in a cage, but wants to be there, is he then "free", since he is doing what he wants to do? If a man is in a cage but doesn't know it, is he "free" since he is not conscious of any limiting factor? What makes a person free? Is it the ability to do anything, and choosing one course over the rest, or is it just the ability to do what you want to do? Are all the options ever really open to us in the first place, or do we commonly determine our level of "freedom" by how much we like the cage we're in?
