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.
