PATRIOTISM, n. Combustible rubbish ready to the torch of any one ambitious to illuminate his name. In Dr. Johnson’s famous dictionary patriotism is defined as the last resort of a scoundrel. With all due respect to an enlightened but inferior lexicographer I beg to submit that it is the first.

Ambrose Bierce (1842-1914?) American writer and journalist

See Johnson. See Bierce's definition of "Patriot."
