It would be a stultification of the responsibility which the course of constitutional history has cast upon this Court to hold that in order to convict a man the police cannot extract by force what is in his mind, but can extract what is in his stomach.

The mark of a truly civilized man is confidence in the strength and security derived from the inquiring mind.

Ultimately there can be no freedom for self unless it is vouchsafed for others; there can be no security where there is fear, and a democratic society presupposes confidence and candor in the relations of men with one another and eager collaboration for the larger ends of life instead of the pursuit of petty, selfish or vainglorious aims.

Ours is an accusatorial, and not an inquisitorial, system - a system in which the State must establish guilt by evidence independently and freely secured, and may not, by coercion, prove its charge against an accused out of his own mouth.

The real rulers in Washington are invisible, and exercise power from behind the scenes.

Democracy is always a beckoning goal, not a safe harbor. For freedom is an unremitting endeavor, never a final achievement.

The ultimate touchstone of constitutionality is the Constitution itself, and not what we have said about it.
