We are all free within our limitations.
If I were a prisoner, shackled to a wall, my mind would still be free to do as it chose.
From 1984: “Freedom is the freedom to say that two plus two equals four.” The protagonist was tortured into relinquishing even this freedom.
If I am chemically depressed or emotionally beaten, I might not be capable of seeing where my freedoms lie. That does not mean they don’t exist. They are there, waiting for us to find them and embrace them again, when and if we are ever capable of doing so.
