That from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth. -  President Abraham Lincoln

A man's country is not a certain area of land, of mountains, rivers, and woods, but it is a principle and patriotism is loyalty to that principle.
