The function of free speech under our system of government is to invite dispute. It may indeed best serve its high purpose when in it invites a condition of unrest, creates dissatisfaction with conditions as they are, or even stirs people to anger.

Restriction of free thought and free speech is the most dangerous of all subversions. It is the one un-American act that could most easily defeat us.

Free speech is not to be regulated like diseased cattle and impure butter. The audience that hissed yesterday may applaud today, even for the same performance.

The right to be let alone is indeed the beginning of all freedom.

The function of the prosecutor under the federal Constitution is not to tack as many skins of victims as possible against the wall. His function is to vindicate the rights of the people as expressed in the laws and give those accused of crime a fair trial.

The most important aspect of freedom of speech is freedom to learn. All education is a continuous dialogue - questions and answers that pursue every problem on the horizon. That is the essence of academic freedom.
