The sin of all time has been the exercise of assumed powers. This is the essence of tyranny. Liberty is a great lesson to learn. It is a great step to vindicate our own freedom. It is more, far more, to learn to leave others free, and free to do just what we perhaps may deem wholly wrong. We must recognize that others have consciences and judgment and rights as well as we, and religiously abstain from the effort to make them better by the use of any means to which we have no right to resort, and to which we cannot resort without abridging the great doctrine, the charter of all our liberties, the doctrine of Human Rights.
