Our amended Constitution is the lodestar for our aspirations. Like every text worth reading, it is not crystalline. The phrasing is broad and the limitations of its provisions are not clearly marked. Its majestic generalities and ennobling pronouncements are both luminous and obscure. This ambiguity of course calls forth interpretation, the interaction of reader and text. The encounter with the Constitutional text has been, in many senses, my life's work.

If we are to be as a shining city upon a hill, it will be because of our ceaseless pursuit of the constitutional ideal of human dignity.

If our free society is to endure, those who govern must recognize human dignity and accept the enforcement of constitutional limitations on their power conceived by the Framers . . . . Such recognition will not come from a technical understanding of the organs of government, or the new forms of wealth they administer. It requires something different, something deeper-a personal confrontation with the wellsprings of our society.

While the machinery of law enforcement and indeed the nature of crime itself have changed dramatically since the Fourth Amendment became part of the Nation's fundamental law in 1791, what the Framers understood then remains true today - that the task of combating crime and convicting the guilty will in every era seem of such critical and pressing concern that we may be lured by the temptations of expediency into forsaking our commitment to protecting individual liberty and privacy.

We current justices read the Constitution in the only way that we can: as 20th-century Americans.

The concept of military necessity is seductively broad, and has a dangerous plasticity. Because they invariably have the visage of overriding importance, there is always a temptation to invoke security "necessities" to justify an encroachment upon civil liberties. For that reason, the military-security argument must be approached with a healthy skepticism.

Death is not only an unusually severe punishment, unusual in its pain, in its finality and in its enormity, but is serves no penal purpose more effectively than a less severe punishment.
