Theodore Roosevelt Quote
Some reformers may urge that in the ages distant future, patriotism, like the habit of monogamous marriage, will become a needless and obsolete virtue; but just at present the man who loves other countries as much as he does his own is quite as noxious a member of society as the man who loves other women as much as he loves his wife. Love of country is an elemental virtue, like love of home.
