This concern with the basic condition of freedom -- the absence of physical constraint -- is unquestionably necessary, but is not all that is necessary. It is perfectly possible for a man to be out of prison and yet not free -- to be under no physical constraint and yet to be a psychological captive, compelled to think, feel and act as the representatives of the national State, or of some private interest within the nation, want him to think, feel and act.
