Speech to the American Legion convention, New York City (27 August 1952); as quoted in "Democratic Candidate Adlai Stevenson Defines the Nature of Patriotism" in Lend Me Your Ears : Great Speeches In History (2004) by William Safire, p. 79 - 80
Context: We talk a great deal about patriotism. What do we mean by patriotism in the context of our times? I venture to suggest that what we mean is a sense of national responsibility which will enable America to remain master of her power — to walk with it in serenity and wisdom, with self-respect and the respect of all mankind; a patriotism that puts country ahead of self; a patriotism which is not short, frenzied outbursts of emotion, but the tranquil and steady dedication of a lifetime. The dedication of a lifetime — these are words that are easy to utter, but this is a mighty assignment. For it is often easier to fight for principles than to live up to them.
