But, though pugnacity and acquisitiveness have been the real foundation of much miscalled patriotism, better motives are generally mingled with these primitive instincts. It is the subtle blend of noble and ignoble sentiment which makes patriotism such a difficult problem for the moralist. The patriot nearly always believes, or thinks he believes, that he desires the greatness of his country because his country stands for something intrinsically great and valuable. Where this conviction is absent we cannot speak of patriotism, but only of the cohesion of a wolf-pack. The Greeks, who at last perished because they could not combine, had nevertheless a consciousness that they were the trustees of civilisation against barbarism; and in their day of triumph over the Persians they were filled, for a time, with an almost Jewish awe in presence of the righteous judgment of God. The 'Persae' of AEschylus is one of the noblest of patriotic poems. The Romans, a harder and coarser race, had their ideal of _virtus_ and _gravitas_, which included simplicity of life, dignity and self-restraint, honesty and industry, and devotion to the state. They rightly felt that these qualities constituted a vocation to empire. There was much harshness and injustice in Roman imperialism; but what nobler epitaph could even the British empire desire than the tribute of Claudian, when the weary Titan was at last stricken and dying: Haec est, in gremium victos quae sola recepit, humanumque genus communi nomine fovit matris non dominae ritu, civesque vocavit quos domuit, nexuque pio longinqua revinxit?
