We don’t leave Anarres, because we are Anarres. But are we kept here by force? What force—what laws, governments, police? None. Simply our own being, our nature as Odonians. It’s your nature to be Tirin, and my nature to be Shevek, and our common nature to be Odonians, responsible to one another. And that responsibility is our freedom. To avoid it would be to lose our freedom. Would you really like to live in a society where you had no responsibility and no freedom, no choice, only the false option of obedience to the law, or disobedience followed by punishment? Would you really want to go live in a prison?”
