Harlan Fiske Stone on Liberty of ConscienceStone, The Conscientious Objector, 21 Col.Univ.Q. 253, 269 (1919) quoted in United States v. Seeger, 380 U.S. 163 (1965).
Both morals and sound policy require that the state should not violate the conscience of the individual. All our history gives confirmation to the view that liberty of conscience has a moral and social value which makes it worthy of preservation at the hands of the state. So deep in its significance and vital, indeed, is it to the integrity of man’s moral and spiritual nature that nothing short of the self-preservation of the state should warrant its violation; and it may well be questioned whether the state which preserves its life by a settled policy of violation of the conscience of the individual will not in fact ultimately lose it by the process.
