The calculated killing of a human being by the state involves, by its very nature, an absolute denial of the executed person's humanity. The most vile murder does not, in my view, release the state from constitutional restraint on the destruction of human dignity.

Debate on public issues should be uninhibited, robust and wide-open and that...may well include vehement, caustic, and sometimes unpleasantly sharp attacks on government and public officials.

The door of the Free Exercise Clause stands tightly closed against any government regulation of religious beliefs as such. Government may neither compel affirmation of a repugnant belief, nor penalize or discriminate against individuals or groups because they hold views abhorrent to the authorities.

It is tempting to pretend that minorities on death row share a fate in no way connected to our own, that our treatment of them sounds no echoes beyond the chambers in which they die. Such an illusion is ultimately corrosive, for the reverberations of injustice are not so easily confined.

More fundamentally, however, the answer to petitioners' objection is that there can be no impairment of executive power, whether on the state or federal level, where actions pursuant to that power are impermissible under the Constitution. Where there is no power, there can be no impairment of power.

The quest for freedom, dignity, and the rights of man will never end.

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.
