I found this graduation speech by Geoffrey Stone for the University of Chicago Law School and thought I would share it.
His main point is:
Throughout American history, the most intense pressure for the sacrifice of liberty has come in time of war. This is only natural, for in wartime the national security is directly threatened. In such circumstances, it is inevitable that grave questions will arise about whether we can afford our freedoms. The challenge is to decide how much sacrifice of freedom is warranted.
One of the lessons of history is that in time of war we not only compromise our liberties, but we do so excessively and to a degree we almost always come to regret. As Justice Robert Jackson once observed, "it is easy, by giving way to the passion, intolerance, and suspicions of wartime to reduce our liberties to a shadow, often in answer to exaggerated claims of security." If we are to avoid repeating the mistakes of the past, we must understand why this happens.
It's worth reading, as he speaks to the meaning of freedom -- and the role of clear-eyed citizens to defend our freedoms against the reflexive suppression of dissent to policies of an invading President --eloquently and concisely.
