Our Constitution assumes that the common sense of the people and their attachment to our country will enable them, after free discussion, to withstand ideas that are wrong. To say that our patriotism must be protected against false ideas by means other than these is, I think, to make a baseless charge. Unless we can rely on these qualities—if, in short, we begin to punish speech — we cannot honestly proclaim ourselves to be a free Nation and we have lost what the Founders of this land risked their lives and their sacred honor to defend.
