Every patriot believes his country better than any other country... In its active manifestation-it is fond of killing-patriotism would be well enough if it were simply defensive, but it is also aggressive... Patriotism deliberately and with folly aforethought subordinates the interests of a whole to the interests of a part... Patriotism is fierce as a fever, pitiless as the grave and blind as a stone.
