蘇格拉底名言︰「智慧意味著自知無知。」除了無知，還有什麼能促使我們進行探索？
傑斐遜
（Thomas Jefferson）︰無知和自由兼具者，過去沒有，將來也不可能有
If a Nation expects to be ignorant and free in a state of civilization, it expects what never was and never will be... if we are to guard against ignorance and remain free, it is the responsibility of every American to be informed."
-- Thomas Jefferson
