"When a juvenile offender commits a heinous crime, the State can exact forfeiture of some of the most basic liberties, but the State cannot extinguish his life and his potential to attain a mature understanding of his own humanity."

“The remedy for speech that is false is speech that is true. This is the ordinary course in a free society. The response to the unreasoned is the rational; to the uninformed, the enlightened; to the straight-out lie, the simple truth.”

“The Supreme Court of Florida has said that the legislature intended the State's electors to "participat fully in the federal electoral process," as provided in 3 U. S. C. §5. That statute, in turn, requires that any controversy or contest that is designed to lead to a conclusive selection of electors be completed by December 12. That date is upon us, and there is no recount procedure in place under the State Supreme Court's order that comports with minimal constitutional standards. Because it is evident that any recount seeking to meet the December 12 date will be unconstitutional for the reasons we have discussed, we reverse the judgment of the Supreme Court of Florida ordering a recount to proceed. Seven Justices of the Court agree that there are constitutional problems with the recount ordered by the Florida Supreme Court that demand a remedy.”

“At the heart of liberty is the right to define one's own concept of existence, of meaning, of the universe, and of the mystery of human life. … people have organized intimate relationships and made choices that define their views of themselves and their places in society, in reliance on the availability of abortion in the event that contraception should fail…. We conclude the line should be drawn at viability, so that, before that time, the woman has a right to choose to terminate her pregnancy…. there is no line other than viability which is more workable. To be sure, as we have said, there may be some medical developments that affect the precise point of viability, but this is an imprecision within tolerable limits. … A husband has no enforceable right to require a wife to advise him before she exercises her personal choices.”

“We must never lose sight of the fact that the law has a moral foundation, and we must never fail to ask ourselves not only what the law is, but what the law should be.”

“The essence of democracy is that the right to make law rests in the people and flows to the government, not the other way around. Freedom resides first in the people without need of a grant from government.”

“Some kinds of government regulation of private consensual homosexual behavior may face substantial constitutional challenge.”
