The eternal struggle in the law between constancy and change is largely a struggle between history and reason, between past reason and present needs. - Felix Frankfurter

[It is anomalous] to hold that in order to convict a man the police cannot extract by force what is in his mind, but can extract what is in his stomach.

One who belongs to the most vilified and persecuted minority in history is not likely to be insensible to the freedoms guaranteed by our Constitution... But as judges we are neither Jew nor Gentile, neither Catholic nor agnostic.

The process of education has naturally enough been the basis of hope for the perdurance of our democracy on the part of all our great leaders, from Thomas Jefferson onwards. To regard teachers—in our entire educational system, from the primary grades to the university—as the priests of our democracy is therefore not to indulge in hyperbole. It is the special task of teachers to foster those habits of open-mindedness and critical inquiry which alone make for responsible citizens, who, in turn, make possible an enlightened and effective public opinion. Teachers must fulfill their function by precept and practice, by the very atmosphere which they generate; they must be exemplars of open-mindedness and free inquiry. They cannot carry out their noble task if the conditions for the practice of a responsible and critical mind are denied to them.
