Free Expression Statement adopted by the MIT faculty 12/21/22
The influential 1949 Lewis Report observed that MIT's mission was "to encourage initiative, to promote the spirit of free and objective inquiry, to recognize and provide opportunities for unusual interests and aptitudes," and to develop "individuals who will contribute creatively to our society." With a tradition of celebrating provocative thinking, controversial views, and nonconformity, MIT unequivocally endorses the principles of freedom of expression and academic freedom.
Free expression is a necessary, though not sufficient, condition of a diverse and inclusive community. We cannot have a truly free community of expression if some perspectives can be heard and others cannot. Learning from a diversity of viewpoints, and from the deliberation, debate, and dissent that accompany them, are essential ingredients of academic excellence.
Free expression promotes creativity by affirming the ability to exchange ideas without constraints. It not only facilitates individual autonomy and self-fulfillment, it provides for participation in collective decision-making and is essential to the search for truth and justice. Free expression is enhanced by the doctrine of academic freedom, which protects both intramural and extramural expression without institutional censorship or discipline. Academic freedom promotes scholarly rigor and the testing of ideas by protecting research, publication, and teaching from interference.
