If patriotism is good, then Christianity, which gives peace, is an idle dream, and the sooner this teaching is eradicated, the better. But if Christianity really gives peace, and if we really want peace, then patriotism is a leftover from barbarous times, which must not only not be evoked and taught, as we now do, but which must be eradicated by all means of preaching, persuasion, contempt, and ridicule. If Christianity is the truth, and if we wish to live in peace, then we must not only have no sympathy for the power of our country, but must even rejoice in its weakening and contribute to it.
"Patriotism or Peace" by Leo Tolstoy, 1896.
