Patriotism means to stand by the country. It does not mean to stand by the President or any other public official save exactly to the degree in which he himself stands by the country. It is patriotic to support him in so far as he efficiently serves the country. It is unpatriotic not to oppose him to the exact extent that by inefficiency or otherwise he fails in his duty to stand by the country. In either event it is unpatriotic not to tell the truth — whether about the President or about anyone else — save in the rare cases where this would make known to the enemy information of military value which would otherwise be unknown to him.
From the article entitled “Lincoln and Free Speech” published in Metropolitan Magazine (May 1918, Volume 47, Number 6) written by American statesman and writer Theodore Roosevelt, who served as the 26th President of the United States from 1901 to 1909. A common variant of the quotation appears as “Patriotism means to stand with the country. It does not mean to stand with the President.” Compare this to this related statement by French philosopher Baron de Montesquieu: “If I knew something that would serve my country but would harm mankind, I would never reveal it; for I am a citizen of humanity first and by necessity, and a citizen of France second, and only by accident.”
