"Liberty is not the right or chance to do what we choose; there is no such liberty as that on earth. No man can do as he chooses....

"What we mean by liberty is civil liberty, or liberty under law; and this means the guarantees of law that a man shall not be interfered with while using his own powers for his own welfare. It is, therefore, a civil and political status...."

      William Graham Sumner, "The Challenge of Facts" (1882).
