~ David Souter

We want order and security, and we want liberty. And we want not only liberty but equality as well.

~ David Souter

There can be no stronger claim to a physician's assistance than at the time when death is imminent, a moral judgment implied by the state's own recognition of the legitimacy of medical procedures necessarily hastening the moment of impending death.
