Freedom to learn is the first necessity of guaranteeing that man himself shall be self-reliant enough to be free.… when the clock of civilization can be turned back by burning libraries, by exiling scientists, artists, musicians, writers and teachers; by disbursing universities, and by censoring news and literature and art; an added burden, an added burden is placed on those countries where the courts of free thought and free learning still burn bright. If the fires of freedom and civil liberties burn low in other lands they must be made brighter in our own.
