By academic freedom I understand the right to search for truth and to publish and teach what one holds to be true. This right implies also a duty: one must not conceal any part of what on has recognized to be true. It is evident that any restriction on academic freedom acts in such a way as to hamper the dissemination of knowledge among the people and thereby impedes national judgment and action.

Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.

I would teach peace rather than war, love rather than hate.
