Prisons Without Walls

It is perfectly possible for a man to be out of prison and yet not free—to be under no physical constraint and yet 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 wants him to think, feel and act. To him the walls of his prison are invisible and he believes himself to be free.
