Even for what would be considered average, sane persons, there are restrictions to the range of options they can mentally apply themselves to.
And even severely mentally disturbed people may have moments of lucidity.
In one sense, all of our actions are fettered - because we are not able to provide the options that we choose from.
I think is is consistent with the point I was making about "freedom" in thought and action being a continuum rather than a black and white/on and off light switch of a distinction.
It appears that one big bone of contention in the free will discussion is that in order to rightfully say we have free will, we would have to be able to provide the options we choose from. Which is a line of reasoning that suggests that in order to really have free will, we would need to be omnipotent.
I guess if free only meant making the most informed decision possible. But usually it just means getting to do what you want to do. It doesn't seem to be necessary to know everything in the universe to pick out a shirt that makes you happy.
Why wouldn't Sophie's choice be free? The options as provided by the Nazis may be considered amoral or absurd, but I do not see why they wouldn't be free.
As I recall the choice was "We are going to kill both of your children, unless you pick one to live." Making that choice, isn't exactly the paradigm of freedom. In fact, it is the paradigm of duress. Saying that if you are allowed any choice at all, no matter how limited or how much you wish to avoid the choice, that you are making a free choice is a pretty misleading use of our language. And yes, if she an an AK-47 under her shawl, and the skill to kill absolutely every MF in the room before they could harm her children, she might have had more alternatives, and a freer choice. But it still wouldn't be a situation she would choose while planning a vacation.
