Schenck v. United States (1919) The most stringent protection of free speech would not protect a man in falsely shouting fire in a theatre and causing a panic… The question in every case is whether the words used are used in such circumstances and are of such a nature as to create a clear and present danger that they will bring about the substantive evils that Congress has a right to prevent.

Meyer v. Nebraska (1923) The challenged statute forbids the teaching in school of any subject except in English. . . Evidently the legislature has attempted materially to interfere with the calling of modern language teachers, with the opportunities of pupils to acquire knowledge, and with the power of parents to control the education of their own. It is said the purpose of the legislation was to promote civic development by inhibiting training and education of the immature in foreign tongues and ideals before they could learn English and acquire American ideals, and "that the English language should be and become the mother tongue of all children reared in this State." It is also affirmed that the foreign born population is very large, that certain communities commonly use foreign words, follow foreign leaders, move in a foreign atmosphere, and that the children are thereby hindered from becoming citizens of the most useful type, and the public safety is imperiled. That the State may do much, go very far, indeed, in order to improve the quality of its citizens, physically, mentally and morally, is clear; but the individual has certain fundamental rights which must be respected. The protection of the Constitution extends to all, to those who speak other languages as well as to those born with English on the tongue.

Gitlow v. New York (1925) For present purposes, we may and do assume that freedom of speech and of the press which are protected by the First Amendment from abridgment by Congress are among the fundamental personal rights and "liberties" protected by the due process clause of the Fourteenth Amendment from impairment by the States . . . That a State in the exercise of its police power may punish those who abuse this freedom by utterances inimical to the public welfare, tending to corrupt public morals, incite to crime, or disturb the public peace, is not open to question . . . And, for yet more imperative reasons, a State may punish utterances endangering the foundations of organized government and threatening its overthrow by unlawful means. These imperil its own existence as a constitutional State.
