The life of a thinking man will probably be divided into two parts -- the first in which he desires to exterminate modern thinkers, and the second in which he desires to watch them exterminating each other. ...

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 insofar 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 anyone else.
