A noble sentiment:
“If the history of civilization has any lesson to teach it is this: there is one supreme condition of mental and moral progress which it is completely within the power of man himself to secure, and that is perfect liberty of thought and discussion. The establishment of this liberty may be considered the most valuable achievement of modern civilization, and as a condition of social progress it should be deemed fundamental.”
-J.B. Bury, A History of Freedom of Thought, p. 182.
