As quoted in Charles Evans Hughes (1951) by Merlo J. Pusey, Vol. II, p. 794
Context: We still proclaim the old ideals of liberty but we cannot voice them without anxiety in our hearts. The question is no longer one of establishing democratic institutions but of preserving them. … The arch enemies of society are those who know better but by indirection, misstatement, understatement, and slander, seek to accomplish their concealed purposes or to gain profit of some sort by misleading the public. The antidote for these poisons must be found in the sincere and courageous efforts of those who would preserve their cherished freedom by a wise and responsible use of it. Freedom of expression gives the essential democratic opportunity, but self-restraint is the essential civic discipline.
