Beware the leader who bangs the drums of war in order to whip the citizenry into a patriotic fervor, for patriotism is indeed a double-edged sword. It both emboldens the blood, just as it narrows the mind. And when the drums of war have reached a fever pitch and the blood boils with hate and the mind has closed, the leader will have no need in seizing the rights of the citizenry. Rather, the citizenry, infused with fear and blinded by patriotism, will offer up all of their rights unto the leader and gladly so. How do I know? For this is what I have done. And I am Caesar.
The validity of this quote's origin is questionable, but it's still really interesting, and I think, very true. Of course, the obvious recent example is the "war" on terrorism, which is not a real war, but more of an ideal, much like the failed "war" on drugs (which still costs us billions of dollars a year, and provides another example for the quote). And in both cases, we lost a little more of our freedom.
